Abstract:
A reactor includes a housing with an input port for liquid feedstock and an exhaust port for gas produced by a liquid gasification process. The housing includes a pressurized reaction chamber with a pair of spaced apart electrodes having inward free ends immersed in the liquid feedstock. One of the electrodes is mounted on an operable shaft, to move inward and outward relative to the other electrode. A drive mechanism for the operable shaft is located outside the reaction chamber to selectively move the shaft. The reaction chamber is pressurized to increase efficiency of the reactor, and the chamber within which the drive mechanism is located is pressurized to substantially the same pressure as the reaction chamber.
Abstract:
A safe, reduced pressure apparatus for generating water vapor from hydrogen and oxygen and feeding high purity moisture to processes such as semiconductor production. The apparatus eliminates the possibility of the gas igniting by maintaining the internal pressure of the catalytic reactor for generating moisture at a high level while supplying moisture gas from the reactor under reduced pressure. A heat dissipation reactor improvement substantially increases moisture generation without being an enlargement in size by efficient cooling of the reactor alumite-treated fins.
Abstract:
A method and apparatus for applying pressure to at least one reactant for delivery from a storage tank to a gas generating system has at least one pump. An operating medium for applying pressure to the reactants is delivered from the pump to the storage tank via a pipe system. The operating medium itself may also be delivered to a reaction chamber as a reactant of the gas generating system.
Abstract:
The present invention is an oxygen generator including a stabilized bismuth oxide body and a plurality of first and second channels. The first channels receive a first gas containing some oxygen and the second channels are sealed at the input and outlet openings and extend generally in parallel to the first channels. Electrodes are disposed on the channel walls of the first and second channels, the electrode composition includes LXM, wherein L is lanthanum, M is manganate, and X is strontium, calcium, lead or barium. The oxygen generator may further include silver disposed over the LXM which thereby decreases the resistivity of the electrodes without the electromigration of the silver. The silver may be mixed with glass to thereby provide improved adherence of the silver to the LXM. A method of making an oxygen generator includes forming a stabilized bismuth oxide body having channels extending therethrough and forming LXM electrodes in the channels. Forming the LXM electrodes in the channels includes mixing an LXM powder with an organic liquid to form a slurry, applying the slurry to the stabilized bismuth oxide body and firing the body. The method may further include forming a silver layer over the LXM in the channels, thereby forming a multi-layer electrode composition having a low resistivity in which the LXM acts as an electromigration barrier for the silver.
Abstract:
A gas generator for generating gas under pressure. The gas generator comprises a device for providing a first gas including a pressure vessel containing the first gas, the first gas being an oxidizing gas; a device for providing a second gas adapted to be oxidized by the first gas and including a pyrotechnic charge for generating the second gas when ignited. An oxidation zone of the gas generator includes an outlet, the first gas and the second gas being adapted to undergo an oxidation reaction in the oxidation zone for generating the gas under pressure. The first gas and the second gas are directed to the oxidation zone such that the oxidation zone contains a mixture of the first gas and the second gas for the oxidation reaction thereof, the second gas being of a sufficiently elevated temperature to initiate the oxidation reaction in the oxidation zone. A back-up catalytic device ensures initiation of the oxidation reaction of the mixture.
Abstract:
A hydrogen storage device (2) includes a vessel (4) and a hydrogen storage bed (6) disposed in the vessel (4). The hydrogen storage bed (6) includes a polymeric material (8) having a plurality of micropores less than about 1 nm in diameter and at least one hydride forming metal (10) imbedded within the polymeric material (8). The device also includes means for optically and thermally decomposing the metal hydride to release hydrogen and means for conveying hydrogen into and out of the storage device (2). The hydrogen storage bed (6) may be made by distributing a hydride forming metal (10) within the polymeric material (8) while the polymeric material (8) is in an uncured state. A metal hydride may be formed in the presence of hydrogen at a pressure such that the hydrogen bonds to the hydride forming metal (10) to form a metal hydride within the polymeric material (8). The hydrogen pressure may be reduced such that the metal hydride dissociates and any dissolved hydrogen escapes through the polymeric material (8), thereby forming a plurality of micropores less than about 1 nm in diameter. The micropores may be molded into the polymeric material (8) by cooling the polymeric material (8).
Abstract:
A gas generator for inflating an inflatable article such as a safety bag or raft, has a reaction chamber (1) surrounded by a ring-shaped filter chamber (2). First gas exit openings (10 to 15) permit generated gas to flow from the reaction chamber into the filter chamber. Second gas exit openings (22) lead from the filter chamber into the inflatable article. A temperature responsive flow control is provided to make sure that the inflation efficiency or the inflation pressure inside the inflated article is substantially constant and substantially independent of the temperature of the gas generator at which the ignition of a gas generating fuel begins. For this purpose the total cross-sectional flow area of the first gas exit openings and/or the average gas flow path length between the first and second gas exit openings is controlled so that with a rising temperature the flow cross-sectional area and/or average path length is increased while the area and/or path length is decreased in response to a decreasing temperature.
Abstract:
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.
Abstract:
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.
