125-758: An elevator ( American English ) or lift ( Commonwealth English ) is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist , although some pump hydraulic fluid to raise a cylindrical piston like a jack . Elevators are used in agriculture and manufacturing to lift materials. There are various types, like chain and bucket elevators , grain augers , and hay elevators . Modern buildings often have elevators to ensure accessibility, especially where ramps aren't feasible. High-speed elevators are common in skyscrapers . Some elevators can even move horizontally. The earliest known reference to an elevator
250-698: A cot–caught merger , which is rapidly spreading throughout the whole country. However, the South, Inland North, and a Northeastern coastal corridor passing through Rhode Island, New York City, Philadelphia, and Baltimore typically preserve an older cot–caught distinction. For that Northeastern corridor, the realization of the THOUGHT vowel is particularly marked , as depicted in humorous spellings, like in tawk and cawfee ( talk and coffee ), which intend to represent it being tense and diphthongal : [oə] . A split of TRAP into two separate phonemes , using different
375-460: A hydraulic crane . In 1846 his work as an amateur scientist was recognized when he was elected a Fellow of the Royal Society . In 1845 a scheme was set in motion to provide piped water from distant reservoirs to the households of Newcastle. Armstrong was involved in this scheme and he proposed to Newcastle Corporation that the excess water pressure in the lower part of town could be used to power
500-456: A marble quarry. It struck Armstrong that much of the available power was being wasted. When he returned to Newcastle, he designed a rotary engine powered by water, and this was built in the High Bridge works of his friend Henry Watson. Little interest was shown in the engine. Armstrong subsequently developed a piston engine instead of a rotary one and decided that it might be suitable for driving
625-520: A pronunciations for example in gap [æ] versus gas [eə] , further defines New York City as well as Philadelphia–Baltimore accents. Most Americans preserve all historical /r/ sounds, using what is known as a rhotic accent . The only traditional r -dropping (or non-rhoticity) in regional U.S. accents variably appears today in eastern New England , New York City , and some of the former plantation South primarily among older speakers (and, relatedly, some African-American Vernacular English across
750-632: A quayside crane specially adapted by himself. He claimed that his hydraulic crane could unload ships faster and more cheaply than conventional cranes. The Corporation agreed to his suggestion, and the experiment proved so successful that three more hydraulic cranes were installed on the Quayside. The success of his hydraulic crane led Armstrong to consider setting up a business to manufacture cranes and other hydraulic equipment. He therefore resigned from his legal practice. Donkin, his legal colleague, supported him in his career move, providing financial backing for
875-585: A "Chart for determining the number and size of elevators required for office buildings of a given total occupied floor area". In 1920, Howard B. Cook presented a paper titled "Passenger Elevator Service". This paper marked the first time a member of the elevator industry offered a mathematical means of determining elevator service. His formula determined the round trip time (RTT) by finding the single trip time, doubling it, and adding 10 seconds. In 1923, Bassett Jones published an article titled "The Probable Number of Stops Made by an Elevator". He based his equations on
1000-534: A building is at its most busy first thing in the morning; however, in more complicated elevator systems, this model does not work. In 1990, Peters published a paper titled "Lift Traffic Analysis: Formulae for the General Case" in which he developed a new formula which would account for mixed traffic patterns as well as accounting for passenger bunching using Poisson approximation. This new General Analysis equation enabled much more complex systems to be analyzed however
1125-588: A career in the law, and so he was articled to Armorer Donkin , a solicitor friend of his father's. He spent five years in London studying law and returned to Newcastle in 1833. In 1835 he became a partner in Donkin's business and the firm became Donkin, Stable and Armstrong. Armstrong married Margaret Ramshaw in 1835, and they built a house in Jesmond Dene , on the eastern edge of Newcastle. Armstrong worked for eleven years as
1250-475: A cast-iron cylinder fitted with a plunger supporting a very heavy weight. The plunger would slowly be raised, drawing in water, until the downward force of the weight was sufficient to force the water below it into pipes at great pressure. The accumulator was a very significant, if unspectacular, invention, which found many applications in the following years. In 1854, during the Crimean War , Armstrong read about
1375-501: A circuit capable of controlling large currents of several kHz. In 2000, the first vacuum elevator was offered commercially in Argentina. Some people argue that elevators began as simple rope or chain hoists (see Traction elevators below). An elevator is essentially a platform that is either pulled or pushed up by mechanical means. A modern-day elevator consists of a cab (also called a "cabin", "cage", "carriage" or "car") mounted on
SECTION 10
#17328514639791500-616: A complex phenomenon of "both convergence and divergence": some accents are homogenizing and leveling , while others are diversifying and deviating further away from one another. Having been settled longer than the American West Coast, the East Coast has had more time to develop unique accents, and it currently comprises three or four linguistically significant regions, each of which possesses English varieties both different from each other as well as quite internally diverse: New England ,
1625-447: A consonant, such as in pearl , car and fort . Non-rhotic American accents, those that do not pronounce ⟨r⟩ except before a vowel, such as some accents of Eastern New England , New York City , and African-Americans , and a specific few (often older ones) spoken by Southerners , are often quickly noticed by General American listeners and perceived as sounding especially ethnic, regional, or antiquated. Rhoticity
1750-505: A diverse set of purposes. In 1823, Burton and Homer, two architects in London , built and operated a novel tourist attraction which they called the "ascending room", which elevated customers to a considerable height in the center of London, providing a panoramic view. Early, crude steam-driven elevators were refined in the ensuing decade. In 1835, an innovative elevator, the Teagle, was developed by
1875-458: A floor at the same time, are usually driven by the same motor. The system increases efficiency in high-rise buildings, and saves space so additional shafts and cars are not required. In 2003, TK Elevator invented a system called TWIN, with two elevator cars independently running in one shaft. In 1901, consulting engineer Charles G. Darrach (1846–1927) proposed the first formula to determine elevator service. In 1908, Reginald P. Bolton published
2000-461: A government committee. The gun proved successful in trials, but the committee thought a higher calibre gun was needed, so Armstrong built an 18-pounder on the same design. After trials, this gun was declared to be superior to all its rivals. Armstrong surrendered the patent for the gun to the British government, rather than profit from its design. As a result he was created a Knight Bachelor and in 1859
2125-586: A merger with the THOUGHT ( caught ) set. Having taken place prior to the unrounding of the cot vowel, it results in lengthening and perhaps raising, merging the more recently separated vowel into the THOUGHT vowel in the following environments: before many instances of /f/ , /θ/ , and particularly /s/ (as in Austria, cloth, cost, loss, off, often, etc.), a few instances before /ŋ/ (as in strong, long, wrong ), and variably by region or speaker in gone , on , and certain other words. Unlike American accents,
2250-431: A mile along the riverside. The population of Elswick, which had been 3,539 in 1851, had increased to 27,800 by 1871. In 1894, Elswick built and installed the steam-driven pumping engines, hydraulic accumulators and hydraulic pumping engines to operate London's Tower Bridge . In 1897 the company merged with the company of Armstrong's old rival, Joseph Whitworth, and became Sir W. G. Armstrong, Whitworth & Co Ltd. Whitworth
2375-636: A nice day , for sure); many are now distinctly old-fashioned (swell, groovy). Some English words now in general use, such as hijacking, disc jockey , boost, bulldoze and jazz , originated as American slang. American English has always shown a marked tendency to use words in different parts of speech and nouns are often used as verbs . Examples of nouns that are now also verbs are interview, advocate, vacuum, lobby, pressure, rear-end, transition, feature, profile, hashtag, head, divorce, loan, estimate, X-ray, spearhead, skyrocket, showcase, bad-mouth, vacation , major, and many others. Compounds coined in
2500-569: A platform within an enclosed space called a shaft or sometimes a "hoistway". In the past, elevator drive mechanisms were powered by steam and water hydraulic pistons or by hand. In a "traction" elevator, cars are pulled up by means of rolling steel ropes over a deeply grooved pulley , commonly called a sheave in the industry. The weight of the car is balanced by a counterweight . Oftentimes two elevators (or sometimes three) are built so that their cars always move synchronously in opposite directions, and are each other's counterweight. The friction between
2625-475: A process of extensive dialect mixture and leveling in which English varieties across the colonies became more homogeneous compared with the varieties in Britain. English thus predominated in the colonies even by the end of the 17th century's first immigration of non-English speakers from Western Europe and Africa. Additionally, firsthand descriptions of a fairly uniform American English (particularly in contrast to

#17328514639792750-657: A series of other vowel shifts in the same region, known by linguists as the " Inland North ". The Inland North shares with the Eastern New England dialect (including Boston accents ) a backer tongue positioning of the GOOSE /u/ vowel (to [u] ) and the MOUTH /aʊ/ vowel (to [ɑʊ~äʊ] ) in comparison to the rest of the country. Ranging from northern New England across the Great Lakes to Minnesota, another Northern regional marker
2875-531: A severe cough, and he had fond memories of the area. In 1863 he bought some land in a steep-sided, narrow valley where the Debdon Burn flows towards the River Coquet near Rothbury. He had the land cleared and supervised the building of a house perched on a ledge of rock, overlooking the burn. He also supervised a programme of planting trees and mosses so as to cover the rocky hillside with vegetation. His new house
3000-570: A small cabinet houses the controller. The equipment is otherwise similar to that of a normal traction or hole-less hydraulic elevator. The world's first machine-room-less elevator, the Kone MonoSpace, was introduced in the year 1996, by Kone . Compared to traditional elevators, it: Its disadvantage was that it could be harder, and significantly more dangerous, to service and maintain. Double-decker elevators are traction elevators with cars that have an upper and lower deck. Both decks, which can serve
3125-540: A solicitor, but during his spare time he showed great interest in engineering, developing the " Armstrong Hydroelectric Machine " between 1840 and 1842. In 1837, he laid the foundations for the engineering and environmental consultancy which is today known as Wardell Armstrong. Armstrong was a very keen angler, and while fishing on the River Dee at Dentdale in the Pennines , he saw a waterwheel in action, supplying power to
3250-514: A survey, completed in 2003, polling English speakers across the United States about their specific everyday word choices, hoping to identify regionalisms. The study found that most Americans prefer the term sub for a long sandwich, soda (but pop in the Great Lakes region and generic coke in the South) for a sweet and bubbly soft drink , you or you guys for the plural of you (but y'all in
3375-453: A variation of American English in these islands. In 2021, about 245 million Americans, aged 5 or above, spoke English at home: a majority of the United States total population of roughly 330 million people. The United States has never had an official language at the federal level, but English is commonly used at the federal level and in states without an official language. 32 of the 50 states, in some cases as part of what has been called
3500-420: A variety of factors. Hydraulic elevators are cheaper, but installing cylinders greater than a certain length becomes impractical for very-high lift hoistways. For buildings of much over seven floors, traction elevators must be employed instead. Hydraulic elevators are usually slower than traction elevators. Elevators are a candidate for mass customization . There are economies to be made from mass production of
3625-642: Is also associated with the United States, perhaps mostly in the Midwest and the South. American accents that have not undergone the cot–caught merger (the lexical sets LOT and THOUGHT ) have instead retained a LOT – CLOTH split : a 17th-century distinction in which certain words (labeled as the CLOTH lexical set ) separated away from the LOT set. The split, which has now reversed in most British English, simultaneously shifts this relatively recent CLOTH set into
3750-637: Is also home to a creole language known commonly as Hawaiian Pidgin , and some Hawaii residents speak English with a Pidgin-influenced accent. American English also gave rise to some dialects outside the country, for example, Philippine English , beginning during the American occupation of the Philippines and subsequently the Insular Government of the Philippine Islands ; Thomasites first established
3875-526: Is common in most American accents despite being now rare in England because, during the 17th-century British colonization, nearly all dialects of English were rhotic, and most North American English simply remained that way. The preservation of rhoticity in North America was also supported by continuing waves of rhotic-accented Scotch-Irish immigrants, most intensely during the 18th century (and moderately during

4000-512: Is in the works of the Roman architect Vitruvius , who reported that Archimedes ( c. 287 BC – c. 212 BC ) built his first elevator probably in 236 BC. Sources from later periods mention elevators as cabs on a hemp rope, powered by people or animals. The Roman Colosseum , completed in 80 AD, had roughly 25 elevators that were used for raising animals up to the floor. Each elevator could carry about 600 pounds (270 kg) (roughly
4125-478: Is no evidence that Armstrong agonised over his decision to go into armament production. He once said: "If I thought that war would be fomented, or the interests of humanity suffer, by what I have done, I would greatly regret it. I have no such apprehension." He also said: "It is our province, as engineers to make the forces of matter obedient to the will of man; those who use the means we supply must be responsible for their legitimate application." Armstrong advocated

William Armstrong, 1st Baron Armstrong William George Armstrong, 1st Baron Armstrong , CB FRS (26 November 1810 – 27 December 1900) was an English engineer and industrialist who founded the Armstrong Whitworth manufacturing concern on Tyneside . He was also an eminent scientist, inventor and philanthropist. In collaboration with
4500-635: Is the set of varieties of the English language native to the United States. English is the most widely spoken language in the United States ; the de facto common language used in government, education, and commerce; and an official language in 32 of the 50 U.S. states . Since the late 20th century, American English has become the most influential form of English worldwide. Varieties of American English include many patterns of pronunciation, vocabulary, grammar and particularly spelling that are unified nationwide but distinct from other English dialects around
4625-463: Is the variable fronting of /ɑ/ before /r/ , for example, appearing four times in the stereotypical Boston shibboleth Park the car in Harvard Yard . Several other phenomena serve to distinguish regional U.S. accents. Boston , Pittsburgh , Upper Midwestern , and Western U.S. accents have fully completed a merger of the LOT vowel with the THOUGHT vowel ( /ɑ/ and /ɔ/ , respectively):
4750-591: The Austro-Hungarian Navy . The first battleship produced at Elswick was HMS Victoria , launched in 1887. The ship was originally to be named Renown , but the name was changed in honour of the Queen's Golden Jubilee. Armstrong drove the first and last rivets. The ship was ill-fated, as she was involved in a collision with HMS Camperdown just six years later in 1893 and sank with the loss of 358 men, including Vice-Admiral Sir George Tryon . An important customer of
4875-644: The Château de Versailles in 1743. Ancient and medieval elevators used drive systems based on hoists and windlasses . The invention of a system based on the screw drive was perhaps the most important step in elevator technology since ancient times, leading to the creation of modern passenger elevators. The first screw-drive elevator was built by Ivan Kulibin and installed in the Winter Palace in 1793, although there may have been an earlier design by Leonardo da Vinci . Several years later, another of Kulibin's elevators

As of the 20th century, the middle and eastern Great Lakes area , Chicago being the largest city with these speakers, also ushered in certain unique features, including the fronting of the LOT /ɑ/ vowel in the mouth toward [a] and tensing of the TRAP /æ/ vowel wholesale to [eə] . These sound changes have triggered

American English speakers have integrated traditionally non-English terms and expressions into the mainstream cultural lexicon; for instance, en masse , from French ; cookie , from Dutch ; kindergarten from German , and rodeo from Spanish . Landscape features are often loanwords from French or Spanish, and

AmE almost always uses -ize in words like realize . BrE prefers -ise , but also uses -ize on occasion (see: Oxford spelling ). There are a few differences in punctuation rules. British English is more tolerant of run-on sentences , called " comma splices " in American English, and American English prefers that periods and commas be placed inside closing quotation marks even in cases in which British rules would place them outside. American English also favors
5500-591: The "standing rope control" for an elevator in 1850. In 1852, Elisha Otis introduced the safety elevator, which prevented the fall of the cab if the cable broke. He demonstrated it at the New York exposition in the Crystal Palace in a dramatic, death-defying presentation in 1854, and the first such passenger elevator was installed at 488 Broadway in New York City on 23 March 1857. The first elevator shaft preceded

Industry and material innovations from the 19th century onwards provide distinctive new words, phrases, and idioms through railroading (see further at rail terminology ) and transportation terminology, ranging from types of roads ( dirt roads , freeways ) to infrastructure ( parking lot , overpass , rest area ), to automotive terminology often now standard in English internationally. Already existing English words—such as store , shop , lumber —underwent shifts in meaning; others remained in
5750-534: The 20th century. The use of English in the United States is a result of British colonization of the Americas . The first wave of English-speaking settlers arrived in North America during the early 17th century, followed by further migrations in the 18th and 19th centuries. During the 17th and 18th centuries, dialects from many different regions of England and the British Isles existed in every American colony, allowing

However, while individuals usually use one or the other, both forms will be widely understood and mostly used alongside each other within the two systems. While written American English is largely standardized across the country and spoken American English dialects are highly mutually intelligible, there are still several recognizable regional and ethnic accents and lexical distinctions. The regional sounds of present-day American English are reportedly engaged in

His last great project, begun in 1894, was the purchase and restoration of the huge Bamburgh Castle on the Northumberland coast, which remains in the hands of the Armstrong family. His wife, Margaret, died in September 1893, at their house in Jesmond. Armstrong died at Cragside on 27 December 1900, aged ninety. He was buried in Rothbury churchyard, alongside his wife. The couple had no children, and Armstrong's heir
6125-816: The Dene. Armstrong entertained several eminent guests at Cragside, including the Shah of Persia , the King of Siam , the prime minister of China and the Prince and Princess of Wales . In 1873 he served as High Sheriff of Northumberland . He was President of the North of England Institute of Mining and Mechanical Engineers from 1872 to 1875. He was elected as the president of the Institution of Civil Engineers in December 1881 and served in that capacity for
6250-408: The Dene. In 1860 he paid local architect John Dobson to design a Banqueting Hall overlooking the Dene, which still survives, though it is now roofless. His house close to Newcastle was convenient for his practice as a solicitor and his work as an industrialist, but when he had more spare time he longed for a house in the country. He had often visited Rothbury as a child, when he was afflicted by

It was claimed that every Japanese gun used in the battle had been provided by Elswick. Elswick was the only factory in the world that could build a battleship and arm it completely. The Elswick works continued to prosper, and by 1870 stretched for three-quarters of
6750-565: The Inland North. Rather than one particular accent, General American is best defined as an umbrella covering an American accent that does not incorporate features associated with some particular region, ethnicity, or socioeconomic group. Typical General American features include rhoticity , the father–bother merger , Mary–marry–merry merger , pre-nasal "short a " tensing , and other particular vowel sounds . General American features are embraced most by Americans who are highly educated or in

In this method, a virtual version of a building is created on a computer, modeling passengers and elevators as realistically as possible, and random numbers are used to model probability rather than mathematical equations and percentage probability. American English American English , sometimes called United States English or U.S. English ,
9000-499: The car does not reach maximum rated speed or acceleration, and added the functionality of express zones. This equation is now referred to as the 'Up peak Calculation' as it uses the assumption that all the passengers are coming into the building from the ground floor (incoming traffic) and that there are no passengers traveling from a higher floor to the ground floor (outgoing traffic) and no passengers traveling from one internal floor to another (interfloor traffic). This model works well if
9125-512: The company Frost and Stutt in England . It was belt-driven and used a counterweight for extra power. In 1845, Neapolitan architect Gaetano Genovese installed the "Flying chair", an elevator ahead of its time in the Royal Palace of Caserta . It was covered with chestnut wood outside and with maple wood inside. It included a light, two benches, and a hand-operated signal, and could be activated from
9250-483: The company produced 45 cranes and two years later, 75. It averaged 100 cranes per year for the rest of the century. In 1850 over 300 men were employed at the works, but by 1863 this had risen to 3,800. The company soon branched out into bridge building, one of the first orders being for the Inverness Bridge, completed in 1855. Armstrong was responsible for developing the hydraulic accumulator . Where water pressure
9375-485: The components, but each building comes with its own requirements like different number of floors, dimensions of the well and usage patterns. Elevator doors prevent riders from falling into, entering, or tampering with anything in the shaft. The most common configuration is to have two panels that meet in the middle and slide open laterally. These are known as "center-opening". In a cascading telescopic configuration (potentially allowing wider entryways within limited space),
9500-406: The country), though the vowel-consonant cluster found in "bird", "work", "hurt", "learn", etc. usually retains its r pronunciation, even in these non-rhotic American accents. Non-rhoticity among such speakers is presumed to have arisen from their upper classes' close historical contact with England, imitating London's r -dropping, a feature that has continued to gain prestige throughout England from
9625-466: The daughter of Addison Potter. Armstrong was educated at the Royal Grammar School, Newcastle upon Tyne , until he was sixteen, when he was sent to Bishop Auckland Grammar School . While there, he often visited the nearby engineering works of William Ramshaw. During his visits he met his future wife, Ramshaw's daughter Margaret, six years his senior. Armstrong's father was set on his following
9750-449: The development of insulated gate bipolar transistors (IGBTs) at the end of the 1980s. The IGBT realized increased switching frequency and reduced magnetic noise in the motor, eliminating the need for a filter circuit and allowing a more compact system. The IGBT also allowed the development of a small, highly integrated, highly sophisticated all-digital control device, consisting of a high-speed processor, specially customized gate arrays, and
9875-453: The difficulties the British Army experienced in manoeuvring its heavy field guns. He decided to design a lighter, more mobile field gun, with greater range and accuracy. He built a breech-loading gun with a strong, rifled barrel made from wrought iron wrapped around a steel inner lining, designed to fire a shell rather than a ball . In 1855 he had a five-pounder ready for inspection by
10000-614: The diverse regional dialects of British English) became common after the mid-18th century, while at the same time speakers' identification with this new variety increased. Since the 18th century, American English has developed into some new varieties, including regional dialects that retain minor influences from waves of immigrant speakers of diverse languages, primarily European languages. Some racial and regional variation in American English reflects these groups' geographic settlement, their de jure or de facto segregation, and patterns in their resettlement. This can be seen, for example, in
10125-409: The doors roll on independent tracks so that while open, they are tucked behind one another, and while closed, they form cascading layers on one side. This can be configured so that two sets of such cascading doors operate like the center opening doors described above, allowing for a very wide elevator cab. In less expensive installations the elevator can also use one large "slab" door: a single panel door
10250-742: The double quotation mark ("like this") over the single ('as here'). Vocabulary differences vary by region. For example, autumn is used more commonly in the United Kingdom, whereas fall is more common in American English. Some other differences include: aerial (United Kingdom) vs. antenna, biscuit (United Kingdom) vs. cookie/cracker, car park (United Kingdom) vs. parking lot, caravan (United Kingdom) vs. trailer, city centre (United Kingdom) vs. downtown, flat (United Kingdom) vs. apartment, fringe (United Kingdom) vs. bangs, and holiday (United Kingdom) vs. vacation. AmE sometimes favors words that are morphologically more complex, whereas BrE uses clipped forms, such as AmE transportation and BrE transport or where
10375-400: The earlier steam-driven elevators, exploiting Pascal's law to provide much greater force. A water pump supplied a variable level of water pressure to a plunger encased inside a vertical cylinder, allowing the platform, carrying a heavy load, to be raised and lowered. Counterweights and balances were also used to increase lifting power. Henry Waterman of New York is credited with inventing
10500-799: The elevator car approaches and leaves them. In 1874, J. W. Meaker patented a method permitting elevator doors to open and close safely. The first electric elevator was built by Werner von Siemens in 1880 in Germany. Inventor Anton Freissler further developed von Siemens' ideas and created a successful elevator enterprise in Austria-Hungary. The safety and speed of electric elevators were significantly enhanced by Frank Sprague , who added floor control, automatic operation, acceleration control, and further safety devices. His elevator ran faster and with larger loads than hydraulic or steam elevators. 584 of Sprague's elevators were installed before he sold his company to
10625-643: The elevator shaft when the car was not being entered or exited. In 1891, American inventors Joseph Kelly and William L. Woods co-patented a novel way to guard elevator shafts against accident, by way of hatches that would automatically open and close as the car passed through them. The first elevator in India was installed at the Raj Bhavan in Kolkata by Otis in 1892. By 1900, completely automated elevators were available, but passengers were reluctant to use them. Their adoption
10750-481: The equations had now become so complex that it was almost impossible to do manually and it became necessary to use software to run the calculations. The GA formula was extended even further in 1996 to account for double deck elevators. RTT calculations establish an elevator system's handling capacity by using a set of repeatable calculations which, for a given set of inputs, always produce the same answer. It works well for simple systems; but as systems get more complex,
10875-489: The first book devoted to this subject, Elevator Service . The summation of his work was a massive fold-out chart (placed at the back of his book) that allowed users to determine the number of express and local elevators needed for a given building to meet a desired interval of service. In 1912, commercial engineer Edmund F. Tweedy and electrical engineer Arthur Williams co-authored a book titled Commercial Engineering for Central Stations . He followed Bolton's lead and developed
11000-449: The first elevator by four years. Construction for Peter Cooper 's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper thought it was the most efficient design. Otis later designed a special elevator for the building. Peter Ellis , an English architect, installed
11125-564: The first elevators that could be described as paternoster elevators in Oriel Chambers in Liverpool in 1868. The Equitable Life Building , completed in 1870 in New York City, is thought to be the first office building with passenger elevators. In 1872, American inventor James Wayland patented a novel method of securing elevator shafts with doors that are automatically opened and closed as
11250-510: The following two centuries) when this ethnic group eventually made up one-seventh of the colonial population. Scotch-Irish settlers spread from Delaware and Pennsylvania throughout the larger Mid-Atlantic region, the inland regions of both the South and North, and throughout the West: American dialect areas that were all uninfluenced by upper-class non-rhoticity and that consequently have remained consistently rhotic. While non-rhoticity spread on
11375-476: The head of his company, he became less involved in its day-to-day running. He appointed several very able men to senior positions and they continued his work. When he married, he acquired a house called Jesmond Dean (sic), which is now demolished, and not to be confused with the nearby Jesmond Dene House . Armstrong's house was to the west of Jesmond Dene , Newcastle, and thus not far from his birthplace, and he began to landscape and improve land that he bought within
11500-939: The hospital , BrE to hospital ; contrast, however, AmE actress Elizabeth Taylor , BrE the actress Elizabeth Taylor ). Often, these differences are a matter of relative preferences rather than absolute rules; and most are not stable since the two varieties are constantly influencing each other, and American English is not a standardized set of dialects. Differences in orthography are also minor. The main differences are that American English usually uses spellings such as flavor for British flavour , fiber for fibre , defense for defence , analyze for analyse , license for licence , catalog for catalogue and traveling for travelling . Noah Webster popularized such spellings in America, but he did not invent most of them. Rather, "he chose already existing options on such grounds as simplicity, analogy or etymology." Other differences are due to
11625-507: The house in which he was born no longer exists, an inscribed granite tablet marks the site where it stood. At that time the area, next to the Pandon Dene , was rural. His father, also called William , was a corn merchant on the Newcastle quayside, who rose through the ranks of Newcastle society to become mayor of the town in 1850. An elder sister, Anne, born in 1802, was named after his mother,
11750-656: The influence of 18th-century Protestant Ulster Scots immigrants (known in the U.S. as the Scotch-Irish ) in Appalachia developing Appalachian English and the 20th-century Great Migration bringing African-American Vernacular English to the Great Lakes urban centers. Any phonologically unmarked North American accent falls under an umbrella known as General American. This section mostly refers to such General American features. Studies on historical usage of English in both
11875-444: The inventor Joseph Swan . As Armstrong spent less and less time at the Elswick works, he spent more and more time at Cragside, and it became his main home. In 1869 he commissioned the celebrated architect Richard Norman Shaw to enlarge and improve the house, and this was done over a period of 15 years. In 1883 Armstrong gave Jesmond Dene , together with its banqueting hall to the city of Newcastle. He retained his house next to
12000-438: The late 18th century onwards, but which has conversely lost prestige in the U.S. since at least the early 20th century. Non-rhoticity makes a word like car sound like cah or source like sauce . New York City and Southern accents are the most prominent regional accents of the country, as well as the most stigmatized and socially disfavored. Southern speech, strongest in southern Appalachia and certain areas of Texas,
12125-427: The mid-nineteenth century onwards, so they "are now more different from each other than they were 50 or 100 years ago", while other accents, like of New York City and Boston, have remained stable in that same time-frame. However, a General American sound system also has some debated degree of influence nationwide, for example, gradually beginning to oust the regional accent in urban areas of the South and at least some in
12250-617: The most formal contexts, and regional accents with the most General American native features include North Midland, Western New England, and Western accents. Although no longer region-specific, African-American Vernacular English , which remains the native variety of most working- and middle-class African Americans , has a close relationship to Southern dialects and has greatly influenced everyday speech of many Americans, including hip hop culture . Hispanic and Latino Americans have also developed native-speaker varieties of English. The best-studied Latino Englishes are Chicano English , spoken in
12375-470: The new venture. In 1847 the firm of W. G. Armstrong & Company bought 5.5 acres (22,000 m ) of land alongside the river at Elswick , near Newcastle, and began to build a factory there. The new company received orders for hydraulic cranes from Edinburgh and Northern Railways and from Liverpool Docks , as well as for hydraulic machinery for dock gates in Grimsby . The company soon began to expand. In 1850
12500-568: The next year. He was conferred with Honorary Membership of the Institution of Engineers and Shipbuilders in Scotland in 1884. In 1886, he was persuaded to stand as a Unionist Liberal candidate for Newcastle , but was unsuccessful, coming third in the election. That same year he was presented with the Freedom of the City of Newcastle . In 1887 he was raised to the peerage as Baron Armstrong , of Cragside in
12625-425: The old Woolwich Arsenal up to date so that it could build guns designed at Elswick. However, just when it looked as if the new gun was about to become a great success, a great deal of opposition to the gun arose, both inside the army and from rival arms manufacturers, particularly Joseph Whitworth of Manchester . Stories were publicised that the new gun was too difficult to use, that it was too expensive, that it
12750-457: The outside, without any effort by the occupants. Traction was controlled by a motor mechanic utilizing a system of toothed wheels. A safety system was designed to take effect if the cords broke, consisting of a beam pushed outwards by a steel spring. The hydraulic crane was invented by Sir William Armstrong in 1846, primarily for use at the Tyneside docks for loading cargo. They quickly supplanted
12875-402: The past forms of a few verbs (for example, AmE/BrE: learned / learnt , burned / burnt , snuck/sneaked , dove/dived ) although the purportedly "British" forms can occasionally be seen in American English writing as well; different prepositions and adverbs in certain contexts (for example, AmE in school, BrE at school ); and whether or not a definite article is used, in very few cases (AmE to
13000-575: The ropes and the pulley furnishes the traction which gives this type of elevator its name. Hydraulic elevators use the principles of hydraulics (in the sense of hydraulic power ) to pressurize an above-ground or in-ground piston to raise and lower the car (see Hydraulic elevators below). Roped hydraulics use a combination of both ropes and hydraulic power to raise and lower cars. Recent innovations include permanent magnet motors, machine room-less rail mounted gearless machines, and microprocessor controls. The technology used in new installations depends on
13125-411: The theory of probabilities and found a reasonably accurate method of calculating the average stop count. The equation in this article assumed a consistent population on every floor. He went on to write an updated version of his equations in 1926 which accounted for variable population on each floor. Jones credited David Lindquist for the development of the equation but provides no indication as to when it
13250-570: The traditional standard accent of (southern) England, Received Pronunciation (RP), has evolved a trap–bath split . Moreover, American accents preserve /h/ at the start of syllables, while perhaps a majority of the regional dialects of England participate in /h/ dropping , particularly in informal contexts. However, General American is also innovative in a number of its own ways: The process of coining new lexical items started as soon as English-speaking British-American colonists began borrowing names for unfamiliar flora, fauna, and topography from
13375-400: The use of renewable energy . Stating that coal "was used wastefully and extravagantly in all its applications", he predicted in 1863 that Britain would cease to produce coal within two centuries. As well as advocating the use of hydroelectricity , he also supported solar power , stating that the amount of solar energy received by an area of 1 acre (4,000 m ) in the tropics would "exert
13500-417: The verb-and-preposition combination: stopover, lineup, tryout, spin-off, shootout , holdup, hideout, comeback, makeover , and many more. Some prepositional and phrasal verbs are in fact of American origin ( win out, hold up, back up/off/down/out, face up to and many others). Noun endings such as -ee (retiree), -ery (bakery), -ster (gangster) and -cian (beautician) are also particularly productive in
13625-561: The weight of two lions) 23 feet (7.0 m) up when powered by up to eight men. In 1000, the Book of Secrets by Ibn Khalaf al-Muradi in Islamic Spain described the use of an elevator-like lifting device to raise a large battering ram to destroy a fortress. In the 17th century, prototypes of elevators were installed in the palace buildings of England and France. Louis XV of France had a so-called 'flying chair' built for one of his mistresses at
13750-403: The width of the doorway that opens to the left or right laterally. These are known as "single slide" doors. Some buildings have elevators with the single door on the shaftway, and double cascading doors on the cab. Elevators that do not require separate machine rooms are designed so that most of their power and control components fit within the hoistway (the shaft containing the elevator car), and
13875-772: The word corn , used in England to refer to wheat (or any cereal), came to denote the maize plant, the most important crop in the U.S. Most Mexican Spanish contributions came after the War of 1812 , with the opening of the West, like ranch (now a common house style ). Due to Mexican culinary influence, many Spanish words are incorporated in general use when talking about certain popular dishes: cilantro (instead of coriander), queso, tacos, quesadillas, enchiladas, tostadas, fajitas, burritos, and guacamole. These words usually lack an English equivalent and are found in popular restaurants. New forms of dwelling created new terms ( lot , waterfront) and types of homes like log cabin , adobe in
14000-609: The world. Any American or Canadian accent perceived as lacking noticeably local, ethnic, or cultural markers is known in linguistics as General American ; it covers a fairly uniform accent continuum native to certain regions of the U.S. but especially associated with broadcast mass media and highly educated speech. However, historical and present linguistic evidence does not support the notion of there being one single mainstream American accent . The sound of American English continues to evolve, with some local accents disappearing, but several larger regional accents having emerged in
14125-557: Was President of the Literary and Philosophical Society of Newcastle upon Tyne from 1860 until his death, as well as twice president of the Institution of Mechanical Engineers . Armstrong gave £11,500 towards the building of Newcastle's Hancock Natural History Museum , which was completed in 1882. This sum is equivalent to over £555,000 in 2010. Lord Armstrong's generosity extended beyond his death. In 1901 his heir, William Watson-Armstrong gave £100,000 (equivalent to £13,712,955 in 2023), for
14250-414: Was aided by a 1945 elevator operator strike in New York City, and the addition of an emergency stop button, emergency telephone, and a soothing explanatory automated voice. An inverter-controlled gearless drive system is applied in high-speed elevators worldwide. The Toshiba company continued research on thyristors for use in inverter control and dramatically enhanced their switching capacity, resulting in
14375-448: Was by this time dead. Armstrong gathered many excellent engineers at Elswick. Notable among them were Andrew Noble and George Wightwick Rendel , whose design of gun-mountings and hydraulic control of gun-turrets were adopted worldwide. Rendel introduced the cruiser as a naval vessel. There was great rivalry and dislike between Noble and Rendel, which became open after Armstrong's death. From 1863 onwards, although Armstrong remained
14500-466: Was called Cragside , and over the years Armstrong added to the Cragside estate. Eventually the estate was 1,729 acres (7.00 km ) and had seven million trees planted, together with five artificial lakes and 31 miles (50 km) of carriage drives. The lakes were used to generate hydro-electricity, and the house was the first in the world to be lit by hydro-electricity, using incandescent lamps provided by
14625-518: Was dangerous to use, that it frequently needed repair and so on. All of this smacked of a concerted campaign against Armstrong. Armstrong was able to refute all of these claims in front of various government committees, but he found the constant criticism very wearying and depressing. In 1862 the government decided to stop ordering the new gun and return to muzzle loaders. Also, because of a drop in demand, future orders for guns would be supplied from Woolwich, leaving Elswick without new business. Compensation
14750-488: Was eventually agreed with the government for the loss of business to the company, which went on legitimately to sell its products to foreign powers. Speculation that guns were sold to both sides in the American Civil War was unfounded. In 1864 the two companies, W. G. Armstrong & Company and Elswick Ordnance Company merged to form Sir W. G. Armstrong & Company. Armstrong had resigned from his employment with
14875-446: Was first proposed. Although the equations were there, elevator traffic analysis was still a very specialist task that could only be done by world experts. That was until 1967 when Strakosch wrote an eight step method for finding the efficiency of a system in "Vertical transportation: Elevators and Escalators". In 1975, Barney and Dos Santos developed and published the "Round Trip Time (RTT) formula", which followed Strakosch's work. This
15000-512: Was his great-nephew William Watson-Armstrong . He was succeeded as chairman of the company by his one-time protégé, Andrew Noble . Such was Armstrong's fame as a gun-maker that he is thought to be a possible model for George Bernard Shaw 's arms magnate in Major Barbara . The title character in Iain Pears ' historical-mystery novel Stone's Fall also has similarities to Armstrong. There
15125-594: Was installed in the Arkhangelskoye near Moscow . The development of elevators was led by the need for movement of raw materials, including coal and lumber , from hillsides. The technology developed by these industries, and the introduction of steel beam construction, worked together to provide the passenger and freight elevators in use today. Starting in coal mines, elevators in the mid-19th century operated with steam power , and were used for moving goods in bulk in mines and factories. These devices were soon applied to
15250-515: Was not available on site for the use of hydraulic cranes, Armstrong often built high water towers to provide a supply of water at pressure – for instance, the Grimsby Dock Tower . However, when supplying cranes for use at New Holland on the Humber Estuary , he was unable to do this because the foundations consisted of sand. After much careful thought he produced the weighted accumulator ,
15375-520: Was presented to Queen Victoria . Armstrong became employed as Engineer of Rifled Ordnance to the War Department . In order to avoid a conflict of interests if his own company were to manufacture armaments, Armstrong created a separate company, called Elswick Ordnance Company , in which he had no financial involvement. The new company agreed to manufacture armaments for the British government and no other. Under his new position, Armstrong worked to bring
15500-491: Was the first formulized mathematical model and is the simplest form that is still used by traffic analyzers today. Modification and improvements have been made to this equation over the years, most significantly in 2000 when Peters published "Improvements to the Up Peak Round Trip Time Calculation" which improved the accuracy of the flight time calculation, making allowances for short elevator journeys when
15625-469: Was written by Noah Webster in 1828, codifying several of these spellings. Differences in grammar are relatively minor, and do not normally affect mutual intelligibility; these include: typically a lack of differentiation between adjectives and adverbs, employing the equivalent adjectives as adverbs he ran quick / he ran quickly ; different use of some auxiliary verbs ; formal (rather than notional) agreement with collective nouns ; different preferences for
