The Thompson Trophy race was one of the National Air Races of the heyday of early airplane racing in the 1930s. Established in 1929, the last race was held in 1961. The race was 10 miles (16 km) long with 50-foot-high (15 m) pylons marking the turns, and emphasized low altitude flying and maneuverability at high speeds. As the race was flown around a closed course, crowds in the grandstands could easily see much of the spectacle.

76-439: There were two series of Thompson races. The first series followed the award of a "Thompson Cup" in the 1929 National Air Races to the winner of the "International Land Plane Free-For-All" (that is, the unlimited class race). Thompson Products (a predecessor to TRW ) decided to sponsor a trophy to be awarded for the next ten years for unlimited class racing (though a stipulation was eventually added excluding women pilots). The trophy

152-453: A gas chromatograph-mass spectrometer (GC-MS) and a combined biological instrument. TRW designed and built the following space observatories : The teams developing the following observatories continued their work as part of Northrop Grumman Aerospace Systems: TRW Systems Group designed and manufactured the Vela series of nuclear detection satellites which monitored the 1963 establishment of

228-621: A TRW subsidiary, was a record label active from the mid-1950s to the early 1960s. Christopher John Boyce was a TRW employee convicted of selling security secrets to the Soviet Union via the Soviet embassy in Mexico City in the mid-1970s. Boyce and his accomplice, Andrew Daulton Lee , were the subjects of the best-selling 1979 Robert Lindsey book The Falcon and the Snowman , and the 1985 film of

304-467: A US$ 5.9 billion hostile bid for TRW. Northrop Grumman, BAE Systems , and General Dynamics contended for the company with Northrop's increased bid of US$ 7.8 billion ultimately being accepted on July 1, 2002. Soon afterward, the automotive assets of LucasVarity and TRW's own automotive group were sold to The Blackstone Group as TRW Automotive . A portion of TRW's Lyndhurst campus was developed as Legacy Village . The headquarters building became home to

380-443: A corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. The poppet valve was invented in 1833 by American E.A.G. Young of

456-603: A division of Ramo-Wooldridge Corp., designed and produced the identical payloads for Pioneer 0 , Pioneer 1 and Pioneer 2 . These were intended to orbit and photograph the Moon , but launch vehicle problems prevented this. NASA launched Pioneer 1 as its first spacecraft on 11 October 1958. It set a distance record from Earth, and provided data on the extent of Earth's radiation belts . Pioneer 10 and 11 were nearly identical spacecraft, designed and fabricated by TRW Systems Group. They were optimized for ruggedness since they were

532-414: A former Apple program manager, publicized concerns that the site had not been properly tested since 2015 after receiving an email from Apple notifying employees of forthcoming vapor intrusion testing. An EPA study in 2019 had confirmed the previous remedies effective, but Gjøvik told TechCrunch cracks in the floor were exposing employees to carcinogenic fumes. She filed a whistleblower complaint with

608-716: A mysterious apparent nuclear test now called the Vela incident . First launched in 1970, the company built all twenty-three reconnaissance satellites in the Defense Support Program (DSP), which are the principal components of the Satellite Early Warning System currently used by the United States. These are operated by the Air Force Space Command , and they detect missile or spacecraft launches and nuclear explosions using sensors that detect

684-469: A pulsed flow control is wanted. The pulse can be controlled by a combination of differential pressure and spring load as required. Presta and Schrader valves used on pneumatic tyres are examples of poppet valves. The Presta valve has no spring and relies on a pressure differential for opening and closing while being inflated. Poppet valves are employed extensively in the launching of torpedoes from submarines . Many systems use compressed air to expel

760-529: A valve gear for double-beat poppet valves in 1842. Criticism was reported in the journal Science in 1889 of equilibrium poppet valves (called by the article the "double or balanced or American puppet valve") in use for paddle steamer engines, that by its nature it must leak 15 percent. Poppet valves have been used on steam locomotives , often in conjunction with Lentz or Caprotti valve gear . British examples include: Sentinel Waggon Works used poppet valves in their steam wagons and steam locomotives. Reversing

836-415: Is a valve typically used to control the timing and quantity of petrol (gas) or vapour flow into or out of an engine, but with many other applications. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against

912-451: Is also found in household cleaners. As a result of pipe and tank degradation, the tanks leaked into the ground, resulting in contaminated soil and groundwater. TCE was later determined to be toxic to humans at high concentrations. In 2013, The Atlantic referred to the site as a "paved-over environmental disaster zone". In the 1980s, the US introduced the federal Superfund program to clean up

988-617: Is enough. The TRW-6425 design was later bought from Oerlikon -Bührle, it was improved and manufactured as the Oerlikon KBA 25 mm. The Ramo-Wooldridge Corp formed Pacific Semiconductors in June 1954, under the leadership of Harper North who had been head of electronics R+D at Hughes Aircraft Company . The funding for this endeavor from Thompson Products was about ten times their initial investment in Ramo-Wooldridge. The original goal

1064-530: The Cleveland Cap Screw Company , founded by David Kurtz and four other Cleveland residents. Their initial products were bolts with heads electrically welded to the shafts. In 1904, a welder named Charles E. Thompson adapted their process to making automobile engine valves and by 1915, the company was the largest valve producer in the United States . Charles Thompson was named general manager of

1140-528: The Gemini missions. The company served the U.S. Air Force as systems engineers on all subsequent ICBM development efforts but TRW never produced any missile hardware because of the conflict of interest . In 1960, Congress spurred the formation of the non-profit Aerospace Corporation to provide systems engineering support to the U.S. government but TRW continued to guide the ICBM efforts. TRW originated in 1901 with

1216-597: The Newcastle and Frenchtown Railroad . Young had patented his idea, but the Patent Office fire of 1836 destroyed all records of it. The word poppet shares etymology with " puppet ": it is from the Middle English popet ("youth" or "doll"), from Middle French poupette , which is a diminutive of poupée . The use of the word poppet to describe a valve comes from the same word applied to marionettes , which, like

1292-624: The Occupational Safety and Health Administration against Apple, which was investigated and dismissed. A site evaluation by the EPA done in August 2021 found that the likelihood for vapor intrusion was low and not expected. Based on field testing done between April 24, 2023 and May 5, 2023, the EPA concluded that vapor intrusion was being prevented. Poppet valve#Internal combustion engine A poppet valve (also sometimes called mushroom valve )

1368-556: The United States Air Force . With continued backing from Thompson Products, Ramo-Wooldridge diversified into computers and electronic components , founding Pacific Semiconductors in 1954. They also produced scientific spacecraft such as Pioneer 1 . Thompson Products and Ramo-Wooldridge merged in October 1958 to form Thompson Ramo Wooldridge Inc., unofficially known as "TRW". In February 1959, Jimmy Doolittle became chairman of

1444-610: The infrared emissions from these intense sources of heat. During Desert Storm , for example, DSP satellites were able to detect the launches of Iraqi Scud missiles and provide timely warnings to civilians and military forces in Israel and Saudi Arabia . The initial seven Tracking and Data Relay Satellite System (TDRSS) were built by TRW to improve communication coverage for the Space Shuttle , International Space Station (ISS), and U.S. military satellites. When first launched in 1983,

1520-534: The Cleveland Clinic Wellness Institute. The TRW headquarters building was demolished in 2023. Bill Gates , the founder of Microsoft , says that he got "his first big break" at age fifteen, debugging energy-grid control software for TRW. "It was kind of scary", Gates said, realizing the things the program was going to help operate. "This thing needs to work". TRW Inc. was active in the development of missile systems and spacecraft, notably,

1596-509: The EPA had not been properly monitoring the site and notififying residents of a possible health issue. The EPA litigated with the responsible parties in order update its notification and testing measures to warn residents about possible exposure as early as possible and keeping people away from any unsafe areas. As of 2016 , the site is owned by GI Partners, an investment company, and has been leased by Apple Inc. since 2015 for research and development as of 2021 . The octagonal glass building

1672-413: The EPA, and geologist Michael Calhoun. In 2014 and 2015, a newly required vapor intrusion test of the surrounding residential area, including homes, apartment buildings, and four schools, showed unacceptable levels of TCE. A 2011 study had revealed TCE caused birth defects and cancer by all pathways of exposure. In 2014, the region's congressional representative Anna Eshoo expressed concerns that

1748-619: The Earth's water cycle in the oceans, lakes, atmosphere, polar ice caps , and vegetation . TRW designed and built the descent engine or (LMDE) for the Apollo lunar lander . Due to the need for a soft landing on the Moon, it was the first throttleable engine for crewed space flight . This, and the requirements for high thrust , low weight , and crushability (in case of landing on a large rock), earned surprising praise from NASA's history pages, considering

1824-553: The Indianapolis 500 twenty-seven times, more than any other engine design. During the period leading up to World War II , through the end of the Korean war , Thompson Products was a key manufacturer of component parts for aircraft engines, including cylinder valves . The TAPCO plant, owned by the U.S. government but operated by Thompson Products, extended for almost a mile along Cleveland's Euclid Avenue. It employed over 16,000 workers at

1900-456: The RW-300 for sales in 1959, one of the first "all-transistor" computers with a power supply that used vacuum tubes . The computer was targeted at industrial control applications, with 1024 analog inputs multiplexed to a 1.9K sample/s 10-bit analog-to-digital converter which was transparent to the programmer. It weighed about 600 lb (270 kg). The real-time operating system

1976-700: The TDRS satellites were the largest, most sophisticated communications satellites built at the time. The seventh vehicle in the series was ordered as a replacement when TDRS-B was lost in the Challenger accident . Launched in 2002, TRW produced the Aqua spacecraft based on their modular standardized satellite bus . A joint project of the U.S. Global Change Research Program ( NASA ), Japan Aerospace Exploration Agency ( JAXA ), and National Institute for Space Research (INPE), Brazil , Aqua delivers 750 Gigabytes per day detailing

2052-463: The advent of the turbojet , complicated matters. It was decided to establish a new series, with "R" (piston engine) and "J" (jet-powered) divisions. The "R" class was for civilian competition; the "J" division was for military pilots and was administered by the United States Air Force . Roscoe Turner , the last winner of the pre-war trophy, refused to relinquish it, but the original molds were located, and two additional casts were made, differing only in

2128-415: The air. Jared Blumenfeld, the former EPA director, said that TCE released in the air after the cleanup efforts reduces the concentrations to levels that eliminate health risks. Blumenfeld said that airborne TCE is not ideal, but the cleanup has reduced the toxins by 90% as of 2013 , according to Max Shahbacian, the project's lead at California State Water Resources Control Board before it was transferred to

2204-523: The board of Space Technology Laboratories (STL), the division which continued to support the Air Force ICBM efforts. Other aerospace companies believed TRW's Air Force advisory role granted it unfair access to their technologies and in September 1959, Congress issued a report recommending that STL be converted to a non-profit organization. With nearly half of STL's employees, The Aerospace Corporation

2280-437: The budget cuts, forcing responsible parties to pay for the cleanup. Scott Pruitt, Trump's head of the EPA threatened to cut budgets again for the enforcement. In 2019, the EPA and Philips Semiconductors agreed to a consent decree, with Northrop Grumman as a signatory, to fund the remaining cleanup and monitoring of the site, along with two nearby sites collectively known as the "Triple Site". In March 2021, Ashley Gjøvik ,

2432-615: The company, which became Thompson Products in 1926. Their experimental hollow sodium -cooled valves aided Charles Lindbergh 's solo flight across the Atlantic. In 1937, Thompson Motor Products bought J.A. Drake and Sons (JADSON). The company made high-performance valves that were used in many racing engines of the day, including the Miller Offy . Dale Drake (son of J.A. Drake) bought the Offy engine design with his partner Louis Meyer in 1946 and won

2508-630: The complexity of the lunar missions: "The lunar module descent engine probably was the biggest challenge and the most outstanding technical development of Apollo". This engine was used on Apollo 13 to achieve free return trajectory and make a minor course correction after damage to the Service Module . After the Apollo program Moon landings, the LMDE was further developed into the TRW TR-201 engine. This engine

2584-454: The country's toxic waste sites. The site TRW (now Northrop Grumman) is responsible for is called the ' TRW Microwave site '. The United States Environmental Protection Agency (EPA) worked with TRW to treat the water with ultraviolet light and oxygenation and excavate the contaminated soil. In 1994, a public health study determined that the groundwater was still unacceptably contaminated, which can cause vapor intrusion . The EPA says

2660-416: The cylinder. Use of automatic valves simplified the mechanism, but valve float limited the speed at which the engine could run, and by about 1905 mechanically operated inlet valves were increasingly adopted for vehicle engines. Mechanical operation is usually by pressing on the end of the valve stem, with a spring generally being used to return the valve to the closed position. At high engine speeds ( RPM ),

2736-526: The early development of the U.S. ICBM program under the leadership of the Teapot Committee led by John von Neumann . TRW pioneered systems engineering, creating the ubiquitous N chart and the modern functional flow block diagram . It served as the primary source of systems engineering for the United States Air Force ballistic missile programs. Space Technology Laboratories (STL), then

2812-463: The early stage of American research, TRW was one of the companies involved in the development of automatic guns of the Bushmaster program, where, under the leadership of engineer Eugene Stoner , the author of the famous M16 rifle, a 25 mm automatic cannon was developed under the internal designation TRW model 6425 , an ordinary system with automatic gas venting and locking the barrel with a rotary bolt

2888-468: The exhaust valve remains beside the cylinder in an upside down orientation. These designs were largely replaced by the overhead valve (OHV) engine between 1904 until late-1960s/early-to-mid 1970s, whereby the intake and exhaust valves are both located directly above the cylinder (with the camshaft located at the bottom of the engine). In turn, OHV engines were largely replaced by the overhead camshaft (OHC) engines between 1950s until 1980s. The location of

2964-497: The financial support of Thompson Products. The detonation of a thermonuclear bomb by the Soviet Union spurred Trevor Gardner to form the Teapot Committee in October 1953. Chaired by John von Neumann , its purpose was to study the development of ballistic missiles , including ICBMs. Ramo and Wooldridge were committee members, and Ramo-Wooldridge Corp. became the lead contractor of the resulting ICBM development effort, reporting to

3040-411: The first man-made objects to pass through the asteroid belt and Jupiter's radiation belt. Simplicity, redundancy , and use of proven components were essential. As NASA's first all-atomic powered spacecraft, these used plutonium-238 units developed by Teledyne Isotopes . Pioneer 10 carried eleven instruments and Pioneer 11 carried twelve for investigating Jupiter and Saturn , respectively. Data

3116-401: The force required to open them. This has led to the development of the balanced poppet or double beat valve , in which two valve plugs ride on a common stem, with the pressure on one plug largely balancing the pressure on the other. In these valves, the force needed to open the valve is determined by the pressure and the difference between the areas of the two valve openings. Sickels patented

3192-519: The founding of corporations like SpaceX . In 1953, the company was recruited to lead the development of the United States' first ICBM . Starting with the initial design by Convair , the multi-corporate team launched Atlas in 1957. It flew its full range in 1958 and was then adapted to fly the Mercury astronauts into orbit. TRW also led development of the Titan missile, which was later adapted to fly

3268-409: The hot valve head to the stem where it may be conducted to the cylinder head. Common in second world war piston engines, now only found in high performance engines. Early engines in the 1890s and 1900s used an "automatic" intake valve, which was opened by the vacuum in the combustion chamber and closed by a light spring. The exhaust valve had to be mechanically driven to open it against the pressure in

3344-500: The legend engraved at the base and by placards identifying the division. Division "R" races were held from 1946 to 1949; Division "J" races (also known as "Military Speed Dashes") were held from 1951 to 1961, except 1952 and 1960. This award -related article is a stub .

It

3420-500: The nuclear Partial Test Ban Treaty . Subsequently, they produced the Advanced Vela series, first launched in 1967, which could detect nuclear air bursts using instruments actually called bhangmeters . It had the first dual-spin attitude control system with the total system momentum controlled to zero. The Vela and Advanced Vela satellites were the first to alert astronomers to the presence of gamma-ray bursts . They also reported

3496-565: The peak of WW II production. As jet aircraft replaced piston-engined aircraft, Thompson Products became a major manufacturer of turbine blades for jet engines. In 1950, Simon Ramo and Dean Wooldridge while working for Hughes Aircraft , led the development of the Falcon radar-guided missile , among other projects. They grew frustrated with Howard Hughes ' management, and formed the Ramo-Wooldridge Corporation in September 1953, with

3572-547: The plane of the port. The main advantage of the poppet valve is that it has no movement on the seat, thus requiring no lubrication. In most cases it is beneficial to have a "balanced poppet" in a direct-acting valve. Less force is needed to move the poppet because all forces on the poppet are nullified by equal and opposite forces. The solenoid coil has to counteract only the spring force. Poppet valves are best known for their use in internal combustion and steam engines, but are used in general pneumatic and hydraulic circuits where

3648-544: The poppet valve which sits inside the combustion chamber is a flat disk, while the other side tapers from the disk shape to a thin cylindrical rod called a "valve stem". In a typical modern mass-production engines, the valves are solid and made from steel alloys . However some engines use hollow valves filled with sodium , to improve heat transfer . Many modern engines use an aluminium cylinder head. Although this provides better heat transfer, it requires steel valve seat inserts to be used; in older cast iron cylinder heads,

3724-404: The poppet valve, move bodily in response to remote motion transmitted linearly. In the past, "puppet valve" was a synonym for poppet valve ; however, this usage of "puppet" is now obsolete. The poppet valve is different from both slide and oscillating valves. Instead of sliding or rocking over a seat to uncover a port, the poppet valve lifts from the seat with a movement perpendicular to

3800-448: The production of computers and monitors . Thompson Ramo Wooldridge officially became TRW Inc. in July 1965. Free of anti-competitive restrictions short of ICBM hardware, STL was renamed TRW Systems Group that same month. In 1968, the company entered the credit reporting industry by purchasing Credit Data Corporation and renaming it TRW Information Systems and Services Inc. The Credit Data group

3952-492: The site has institutional controls to protect people from contact with affected water. Drinking water in the area comes from Hetch Hetchy and municipal wells. In the 2000s, a bioremediation method developed by Stanford University using bacteria in molasses to naturally breakdown the TCE into harmless sub-compounds was implemented. Other measures included engineering vapor pathways to avoid direct human contact by releasing it into

4028-449: The throttle is abruptly closed. Historically, valves had two major issues, both of which have been solved by improvements in modern metallurgy . The first was that in early internal combustion engines, high wear rates of valves meant that a valve job to regrind the valves was required at regular intervals. Secondly, lead additives had been used in petrol (gasoline) since the 1920s, to prevent engine knocking and provide lubrication for

4104-669: The time the book was written, TRW was in the business of credit reporting. However, there is no TRW building in Delaware , where the demolition purportedly happens. TRW equipment/boxes can be seen stored and being unloaded in the film Close Encounters of the Third Kind during scenes filmed at Devils Tower. In the 1960s and 1970s, TRW stored trichloroethylene (TCE), a critical chemical for cooling and degreasing computer chips , in tanks deep underground in Sunnyvale, California for later use. TCE

4180-417: The torpedo from the tube , and the poppet valve recovers a large quantity of this air (along with a significant amount of seawater) in order to reduce the tell-tale cloud of bubbles that might otherwise betray the boat's submerged position. Poppet valves are used in most piston engines to control the flow of intake and exhaust gasses through the cylinder head and into the combustion chamber . The side of

4256-432: The twisting path of the intake and exhaust gasses had major drawbacks for the airflow, which limited engine RPM and could cause the engine block to overheat under sustained heavy load. The flathead design evolved into intake over exhaust (IOE) engine , used in many early motorcycles and several cars. In an IOE engine, the intake valves were located directly above the cylinder (like the later overhead valve engines ), however

4332-466: The valve seats are often part of the cylinder head. A gap of 0.4–0.6 mm (0.016–0.024 in) is present around the valve stem, therefore a valve stem oil seal is used to prevent oil being drawn into the intake manifold and combustion chamber. Typically, a rubber lip-type seal is used. A common symptom of worn valve guides and/or defective oil seals is a puff of blue smoke from the exhaust pipe at times of increased intake manifold vacuum , such as when

4408-466: The valves is broadly the same between OHV and OHC engines, however OHC engines saw the camshaft located to the top of the engine with the valves and OHC engines often have more valves per cylinder. Most OHC engines have an extra intake and an extra exhaust valve per cylinder (four-valve cylinder head), compared with the design of two valves per cylinder used by most OHV engines. However some OHC engines have used three or five valves per cylinder. James Watt

4484-454: The valves, via several intermediate mechanisms (such as pushrods , roller rockers and valve lifters ). The shape of the cams on the camshaft influence the valve lift and determine the timing of when the valves open. Early flathead engines (also called L-head engines ) saw the valves located beside to the cylinder(s), in an "upside down" orientation parallel to the cylinder. Although this design made for simplified and cheap construction,

4560-462: The valves. Modern materials for the valves (such as stainless steel) and valve seats (such as stellite ) allowed for leaded petrol to be phased out in many industrialised countries by the mid-1990s. Exhaust valves are subject to very high temperatures and in extreme high performance applications may be sodium cooled. The valve is hollow and filled with sodium, which melts at a relatively low temperature and, in its liquid state, convects heat away from

4636-405: The weight of the valvetrain means the valve spring cannot close the valve as quickly enough, leading to valve float or valve bounce . Desmodromic valves use a second rocker arm to mechanically close the valves (instead of using valve springs) and are sometimes used to avoid valve float in engines that operate at high RPM. In most mass-produced engines, the camshaft (s) control the opening of

They produced some of the first commercially available digital signal processing ICs including the TDC1008 multiplier-accumulator . They also made the first 8-bit flash ADC IC, the TDC1007, resulting in an Emmy Award for analog/digital video conversion technology. TRW also pioneered gallium arsenide (GaAs) chip applications for local multipoint distribution service (LMDS) systems, radios, and satellite communications. Bel Canto Stereophonic Recordings,

4940-634: Was achieved by a simple sliding camshaft system. Many locomotives in France, particularly those rebuilt to the designs of Andre Chapelon, such as the SNCF 240P , used Lentz oscillating-cam poppet valves, which were operated by the Walschaert valve gear the locomotives were already equipped with. The poppet valve was also used on the American Pennsylvania Railroad 's T1 duplex locomotives , although

5016-429: Was designed by Walter Sinz and is now at Air and Space Museum . Sinz also made a pair of 10-foot-tall (3.0 m) models of the trophy for promotional purposes. Races were held for the next ten years, ending in September 1939. Further races in this series were precluded by the onset of war. After World War II the original trophy was (according to stipulation) retired. Also, advances in airplane technology, especially

5092-471: Was formed in 1970 to compete with Dun & Bradstreet , from the combination of TRWISS and ESL Incorporated to specialize in technical strategic reconnaissance .

In 1965, engineers Don Nelson and Dick Pick at TRW developed the Generalized Information Retrieval Language and System, for use by the U.S. Army to control the inventory of Cheyenne helicopter parts. This developed into the Pick Database Management System which is still in use as of 2016. TRW LSI Products, Inc.

5472-524: Was to produce the recently invented transistor for commercial sales. In 1957, Howard Sachar and Sanford "Sandy" Barnes invented the Varicap electronic component (also known as the varactor diode) at Pacific Semiconductors. This device reduced the physical size of radio tuners and eliminated the need for moving mechanical parts. This simplified the implementation of remote control TV tuners. Sachar and Barnes were awarded an Emmy in 2007. The company manufactured

5548-568: Was transmitted back to Earth at 8 watts , 128 bytes/s at Jupiter, and 1 byte/s from further out. Pioneer 10 was the first man-made object to pass the planetary orbits and its last telemetry was received in 2002, thirty years after launch. TRW Systems Group designed and built the instrument package which performed the Martian biological experiments , searching for life aboard the two Viking Landers launched in 1975. The 15.5 kg (34 lb) system performed four experiments on Martian soil using

5624-608: Was used in the second stage Delta-P of the Delta launch vehicle for 77 launches between 1972–1988. At the turn of 1964-65, the United States started the ambitious Bushmaster program to create small-caliber assault guns for arming promising infantry fighting vehicles (IFVs) of the American Army. The result of this program was the creation of a whole series of automatic cannons with an external automatic drive in caliber from 25 to 40 mm, which received their own general name Bushmaster . At

5700-528: Was using poppet valves to control the flow of steam into the cylinders of his beam engines in the 1770s. A sectional illustration of Watt's beam engine of 1774 using the device is found in Thurston 1878:98, and Lardner (1840) provides an illustrated description of Watt's use of the poppet valve. When used in high-pressure applications, for example, as admission valves on steam engines, the same pressure that helps seal poppet valves also contributes significantly to

5776-625: Was written by John Neblett, and was the intellectual precursor of the RSX-11 operating system for the PDP-11 . The TRW-130 computer was introduced in 1961, and designated the AN/UYK-1 by the U.S. Navy as part of its pre-GPS TRANSIT (NAVSAT) satellite-based location system . It used Doppler shifts to compute a location in about 15 minutes, and had rounded corners to allow installation in submarines. The Transistor Transistor Logic (TTL) logic gate, which
