摘要： A non-welded pyrotechnic gas-generating inflator apparatus which comprises: a domed diffuser member, open at one end; a closure plate member sealing the open end of the diffuser member, the members being mechanically sealed by rolling a peripheral lip portion of the diffuser member over the outer circumference edge of the closure plate member at an angle of about 180 degrees to a remaining lateral wall portion of the diffuser member, and inserting a locking ring member against a bottom surface of the closure member within the periphery of the rolled lip, the locking ring being configured to engage an inner terminal edge portion of the lip, thereby forming a sealed inflator housing; a sufficient amount of a combustible gas generant material within said housing to produce, upon the combustion thereof, a volume of a gaseous product sufficient to substantially inflate an automobile air bag within about 30-60 milliseconds; a combustion initiating device positioned within the housing adjacent the gas generant and a filter assembly for filtering the combustion product prior to its discharge from the inflator, the filter assembly circumferentially surrounding the gas generant within the housing. In fabricating the inflator, the filter assembly is simply lowered into position within the diffuser and the propellant is lowered into the filter cavity. Subsequently, the closure member is mated to the open end of the diffuser and the lip of the diffuser is rolled over the outer edge of the closure by a rotating mechanical head in the area where they overlap to form a seal therebetween.

摘要： A gas generator to produce formaldehyde gas in enclosed spaces such as animal houses or for conveying such gas to inaccessible areas through a flexible hose which includes a base and hood mounted thereon. The base is in the form of an open topped container having a heating element oriented under the bottom wall thereof and in heat exchange relation to water and paraformaldehyde flakes or formalgen powder in shallow compartments interiorly of the container for producing formaldehyde gas and water vapor that is heated above ambient temperature. The container includes air inlet slots adjacent to but below the open top and below the lower edge of the hood which is supported on supporting ledge structures on the interior of the container whereby air is entrained into the upwardly moving gas and water vapor for mixing therewith and assisting in disseminating the gas into all areas of the enclosed space when the gas, moisture and air mixture is discharged from an opening in the upper end of the hood.

摘要： A replaceable cartridge-type oxygen generator is described including a quick-opening pressure casing containing a chemical oxygen-generating cartridge having a severable hermetically-sealed container and an ignition device, the casing further including an actuating device capable of actuating the ignition device only when the cartridge is disposed within the casing and the casing is closed. The casing further includes a high-volume vent automatically effective in case of the sudden build-up of a high pressure, such as may be caused by the ignition of a contaminant. Also described is an oxygen supply system including a plurality of such generators connected to an outlet manifold having pressure sensing means controlling the ignition of the cartridges.

摘要： The disclosed gas flow sensor has an orifice connected in an oxygen conduit and a pressure switch connected to the conduit by having a pressure chamber communicating with the conduit. The chamber terminates at a diaphram which is operatively coupled to a normally open microswitch by a spring loaded rod. As the flow rate of oxygen flowing through the conduit drops below a permissible minimum magnitude, back pressure on the orifice decreases so as to close the microswitch to provide a control signal. A bypass valve is connected across the orifice to prevent the oxygen pressure within the conduit from excessively increasing.

摘要： Three chlorate candles are connected to a common conduit to which a normally open pressure switch is connected on the downstream side. The switch closes in response to a flow rate less than its predetermined minimum magnitude of oxygen from each candle flowing through the conduit. The pressure switch and one thermal switch for each candle except the last one are serially interconnected across a DC source through a resistor. When that candle first ignited is weakened in generation of oxygen, the next candle is ignited with the closure of the two serially connected switches and through the resulting heating of the associated resistor. The third candle is similarly ignited.

摘要： An oxygen generator for welding, cutting and brazing work includes a gas-tight container and a cartridge holder for cartridges giving off oxygen when burned. The gas-tight container is constructed as a pressure tank and envelops the cartridge holder in such a way so as to leave a storage volume which is capable of accommodating the amount of oxygen given off by burning at least one cartridge without exceeding the pressure limits of the pressure tank.

摘要： A gas generator for an inflatable life raft having a gas-generating chamber filled with a gas-generating composition which generates gas by chemical reaction, either a chemical cooling chamber or a physical cooling-and-filtering chamber or both, a gas passage in communication with a safety valve, and an ignition device which provides rotational friction between a friction means and a frictional igniting agent. The gas generator has the advantages that it is not influenced by the environmental temperature, a gas temperature drop due to adiabatic gas expansion accompanying the gas discharge does not occur and therefore the generated gas can very reliably be discharged, the gas is fully cleaned, troubles due to abnormality of the gas-generating composition can be avoided, and it can be made light and small.
