Gas-Operated - Wikipedia, the free encyclopedia The piston is forced backwards by the gas, and is connected to the breech of the gun, which is unlocked by the backwards motion induced by the piston when the round leaves the barrel. The M16 uses direct impingement, which is a version of gas operation without a piston. Usually, the speed at which the weapon fires is determined by a regulator, which controls the gas flow to the piston. en.wikipedia.org /wiki/Gas-actuated   (235 words)

Gas The word "gas" was probably made by a Flemish chemist as a re-spelling of his pronunciation of the Greek word chaos. The kinetic energy in a gas is the second greatest of the states of matter (after plasma). Because of this increased kinetic energy, gas atoms and molecules tend to bounce off of one another, more so as the kinetic energy is increased. hallencyclopedia.com /Gas   (373 words)

Gas-operated premixing burner - Patent 5482457 The invention relates to a gas-operated premixing burner for the combustion chamber of, for example, a gas turbine in which, within a premixing space, the fuel injected by means of a plurality of nozzles is intensively mixed with the combustion air prior to ignition, the nozzles being arranged around a burner axis. In a gas-operated premixing burner for the combustion chamber of a gas turbine, the fuel injected within a premixing space (21) by means of a plurality of nozzles (17) is intensively mixed with the combustion air prior to ignition. For this purpose, gas inlet openings 17 in the form of nozzles, distributed in the longitudinal direction, are provided in the region of the tangential slots in the walls of the two partial bodies. www.freepatentsonline.com /5482457.html   (1937 words)

Gas-delayed blowback - Wikipedia, the free encyclopedia Gas-delayed blowback (also called gas-retarded blowback) is a firearm operating principle (not to be confused with gas-operated). Gas-delayed blowback is one of the rarer operating principles. However, propellant gases are vented from the barrel into a cylinder with a piston that delays the opening of the bolt. en.wikipedia.org /wiki/Gas-delayed_blowback   (105 words)

Liquid gas-operated lighter, particularly pocket lighter - Patent 4496309 However, due to the temperature dependency of the vapor pressure, the amount of gas discharged inevitably increases and, thus, the flame height increases with rising temperature, wherein the flame height must meet the legal requirements even in the case of the maximum vapor pressure to be expected during practical use. The space of the gas passage 17 is not even filled with liquid gas because, if the valve--as usual--has been closed while the lighter is still in the vertical position, no liquid gas can reach the passage even when the lighter is subsequently carried in the pocket in any possible position. At a gas vapor pressure of 1 to 6 bars, the fuel amount flowing through is essentially linear to the pressure. www.freepatentsonline.com /4496309.html   (4754 words)

American Hunter, The: Which semi-auto shotgun is best? But in the case of the gas-operated shotguns, part of the carbon and other debris are injected through the gas ports, and the action opens much quicker, permitting far more dirt to enter the action. As the expanding gas enters the cylinder it forces the piston to the rear, which, by means of a linkage or rod, causes the breechbolt to unlock and move to the rear. The high-pressure gas is directed through these ports into a cylinder with a moving piston. www.findarticles.com /p/articles/mi_qa3730/is_200009/ai_n8922851   (1476 words)

The Humphrey gas operated water pump at Barmera South Australia By means of an interlocking apparatus operated by pressures within the combustion head, the exhaust and scavenge air valves were released when the explosion occurred and the gas mixture valves were locked in the closed position. The gas mixture valves alone being free to operate, a new charge of inflammable gas and a small amount of air is admitted into the combustion chamber, which mingling with the scavenge air taken in on the previous stroke, forms a fresh combustion mix. The gas for the Cobdogla Pumps was originally supplied by two updraft producers with scrubbing and tar extracting plant and the fuel used being mallee, box and redgum wood, which was supplied from the extensive wood stacks situated to the North in 6 ft lengths. freeenergy2000.tripod.com /humphreypump.htm   (2006 words)

PRESS RELEASE Aspen Acquires New Gas Production / Announces Earnings During the last 3 years, Aspen participated in the drilling of 15 operated wells, 12 of which were completed as gas wells and 3 dry holes which were plugged and abandoned, a success rate of 80%. The acquisition consists of 4 operated gas wells and 1 non-operated gas well located in various fields in the vicinity of Aspen's existing operations. Because of gas discoveries and acquisitions made during the previous twelve months and favorable gas prices, which averaged $4.82 per MMBTU during the quarter ended September 30, 2003 and are currently approximately $6.00 per MMBTU, Aspen expects positive earnings for the current fiscal year. www.marketwire.com /mw/release_html_b1?release_id=60987   (860 words)

49637.010712&ELEMENT_SET=DECL Case 3821 Method of producing gas-operated vehicle safety devices and the pyrotechnic gas- generating substances produced using the method The pyrotechnic gas-generating substance in an airbag device is intended to quickly fill the cloth bag with gas so that it provides a shock absorbent protection between the passenger and the interior of the vehicle. An example of a gas-generating substance with a suitable combustion rate for certain gas operated vehicle safety devices is one containing approximately 70% by weight guanidine dinitromethane as fuel and approximately 30% by weight potassium dinitromethane as oxygen generator. The gas generated in all such vehicle safety applications shall not therefore contain hot solid particles which could burn through the main system components, the gas filled cloth bags and injure passengers or place the entire function of the safety device at risk. www.wipo.int /cgi-pct/guest/getbykey5?KEY=01/49637.010712&ELEMENT_SET=DECL   (1622 words)

A Brief History of the Manufactured Gas Industry in the United States How many operated at a given time is difficult to say--a handful of commercial plants operated in 1816, nearly 400 in 1860. By the late 1950s only a few plants operated, largely supplying feedstocks to a chemical industry that was ever increasingly relying upon the petroleum industry for its raw materials. The numbers are more difficult to discern in later years, but there is a substantial decline in the number of manufactured gas plants in operation as the century progressed. www.heritageresearch.com /manufactured_gas_D.htm   (317 words)

Principles of Firearms -- Operating Systems -- Gas Perhaps the cleanest solution to gas operation (pun?) is the tappet which localizes gas and propellant residue in the tappet/cylinder area and away from the rest of the system. The gas piston on the AK has sharp forward edges which in theory scrape burnt propellant buildup off the walls of the gas cylinder and vent it out the relief ports. Because gas residue can potentially jam the system and be difficult to dislodge, most gas operating systems are claimed to posses self-cleaning or non-user-maintenance parts. www.rkba.org /guns/principles/operating-systems/gas.html   (1095 words)

USATODAY.com - Calif. clears plan to run telecoms in gas pipelines Gas distributionlines typically run down the center of a street, with smaller "service" lines branching off to individual homes and other buildings. Southern California Gas operates 34,400 miles of distribution gas lines and San Diego Gas and Electric 4,000 in a area extending from about Fresno in California's Central Valley south to the California-Mexico border. Mike Hale, director of gas distribution for the utilities, said the CPUC's decision covered the entire service area but set up an initial three-year trial period that limits the miles for fiber optic lines while the utilities and regulators study the service and costs. www.usatoday.com /tech/news/techinnovations/2003-10-03-fiber-plus-gas-joke-here_x.htm   (451 words)

gas-operated relay - G - Transpower Internet Buchholz is used as a generic name for this type of gas relay. It will also collect gas from incipient fault or air from within the transformer and initially give an alarm, and, if it continues, a trip. A surge of oil or gas from an explosive fault will give a trip, removing the transformer from service. www.transpower.co.nz /?id=1707   (91 words)

Stun-ning Sales: The Airsoft Gun & Ammo Store - About Airsoft Products Guns are available in three types: spring operated, gas operated and battery operated.
