	A Gas Springs Informational Page, About Industrial Springs.
		Gas springs may be referred to as gas props, shocks, dampers, struts or lifts, and they utilize compressed, high-pressure gas to exert a force for extension.
		Gas springs are being used in automobiles to better continuously position the trunks and hoods, and some have started using fl nitrate instead of chrome or stainless steel because it is more corrosive-resistant than chrome and less expensive than stainless steel.
		Locking gas springs use a mechanism that allows the rod to be locked at any time by the actuation of a plunger extending from the rod: when the plunger is released the rod locks its position, when the plunger is pushed down the rod moves normally.

	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.
		Usually, the speed at which the weapon fires is determined by a regulator, which controls the gas flow to the piston.
		The M-16 uses direct impingement, which is a version of gas operation without a piston.

	Gas actuated
		Gas actuated refers to a particular system for implementing automatic re-loading for guns, the others being recoil actuated[?] and blowback.
		In a gas actuated system some of the expanding gases from the round being fired are routed from behind the muzzle to the piston.
		The piston 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.

	Gas primed powder actuated tool - US Patent 5842623 (Site not responding. Last check: 2007-10-26)
		The combustible gas is lead-free such that the operator and the environment are not exposed to dangerous lead residue during use.
		Since the quantity of gas required is considerably less than that required with a pneumatically actuated tool, temperature increase in the tool chamber during extended use is minimized reducing the need for external cooling.
		The removal of gas 62 from the pressurized cylinder 60 to the powder actuated tool reduces the pressure in the pressurized cylinder 60 causing a portion of the compressed liquid to boil, increasing the volume of gas and returning the pressure to equilibrium.

	Stirling cycle heat engines - United States Patent RE29,518
		As the actuating shaft 15 is attached to the vessel 3 the two move in a reciprocating manner as one.
		The helium gas is caused to move between chambers H, C, by way of the annular gap 2 in a reciprocating manner by oscillation of the displacer piston member 4 and with a cyclic change of temperature and pressure.
		The gas pressures in each of the chambers H, C, are always substantially equal and rise and fall together as the gas is alternately heated and cooled.

	Single control for gas actuated fire extinguishers - Patent 4224994
		A small portion of the gas released from the first gas cartridge is responsible for the activation of a second cylinder-piston device associated with a second gas cartridge to cause the release of gas.
		Activation of the discharge mechanism requires that the piston of the housing cylinder-piston associated with the first gas cartridge is motivated such that the piston rod punctures the diaphragm of the first gas cartridge, whereafter the release of gas is conducted to an associated extinguishing tank to cause the release of extinguishing chemical therefrom.
		A portion of the gas from the first gas cartridge is delivered to a first cylinder chamber of the second cylinder-piston to cause the contained piston to puncture the diaphragm of the second gas cartridge.

	Automatically controlled cleaning fluid circuit for a foam generating apparatus and method - Patent 4073664
		An electrical proximity switch 84, which actuates upon the detection of the presence and absence of metal, is mounted on the inside of the tank to sense the presence or absence of the foam gun head 82.
		Thus, the circuit to the valve actuator 180 of the gas purge valve 30 is open, the valve actuator 180 is not energized, and the valve 30 remains in its normal closed position.
		When the purging gas for the foam gun head 82 is provided from the nitrogen storage tank 2 used to pressurize the reactant storage tanks 4 and 6, the pressure of the gas flowing to the foam gun head 82 is reduced from the pressure flowing to the storage tanks 4 and 6.

	Gas Pistols
		The gas is either injected into a reservoir chamber within the gun or attached to an exterior assembly containing the gas canister and an expansion tank.
		Activated by the trigger, gas is released at a valve atop the reservoir or from the expansion tank, depending on the design.
		Essentially, the Blowback effect is created by directing the gas to an interior chamber within the slide of the AirSoft gun, causing it to move rearwards from the expanding gas, hence the "Blowback" action.

	Magnetostrictive Heat Switch for Cryogenic Use
		A magnetostrictively actuated heat switch has been proposed for use in a variety of cryogenic equipment, including adiabatic-demagnetization refrigerators, calorimeters, and cool-ers for high-performance infrared cameras.
		In the case of externally mechanically actuated switches, the mechanical connections between the switches and the outside environment are heat-conduction paths, along which heat leaks into the affected cryogenic chambers.
		The use of a polycrystalline form of this alloy would eliminate the need for a return spring that must be used with the single-crystal form of the alloy, enabling a reduction in the weight and complexity of the switch.

		Farting, also known as flatulence, is the act of passing intestinal gas from the anus.
		Intestinal gas comes from several sources: air we swallow, gas that seeps into our intestines from our blood, gas produced by chemical reactions in our guts, and gas produced by bacteria living in our guts.
		However, the farter probably smells it last because the fart is propelled away from the body in the opposite direction of the farter's nose.
