Abstract: An electronic controller (16) controls the operation of an electrochemical oxygen generating system (14) producing a desired gas. The product gas is fed to a storage unit (12) or a regulator (28) and pulsing valve (28) controlling the gas flow to a user. A two-stage system (180) combines a low pressure 100 and a high pressure (150) gas generating subsystems. The low pressure subsystem (100) uses IMAT's (106) to pump oxygen from ambient air to generate a low-pressure. The high pressure subsystem (150) uses IMAT's (160) to pump oxygen to high-pressure oxygen storage devices (194).

Abstract: A gas generation method and apparatus, capable of use in an aircraft, generates oxygen with at least one On Board Oxygen Generating System (OBOGS) and generates an inert gas with at least one On Board Inert Gas Generating System (OBIGGS) and selectively supplies an auxiliary supply of inert gas utilizing a waste gas output of the at least one OBOGS. The inert gas can include nitrogen. An auxiliary source of oxygen can also be provided. Control valves can be used to selectively supply the waste gas output of the at least one OBOGS to the atmosphere or to either of two locations. The oxygen can be used in a passenger compartment of the aircraft and the inert gas used in either a fuel tank or cargo bay of the aircraft.

Abstract: The present invention relates generally to on board inert gas generating systems, and more particularly, to an on board inert gas generating system having a fast warm up feature. Even more particularly, the present invention relates to a method and apparatus for quickly warming up a permeable membrane air separation system.

Abstract: An anti-G system is used to combat the push-pull effect experienced by airmen during and after a transition from a period of low or negative G force levels to high G force levels. The anti-G system includes an anti-G controller configured to receive signals indicative of airman acceleration and anti-G garment pressure. The anti-G controller is coupled to a valve controller controlling fill and vent valves controlling the pressure level in the anti-G garment. As the anti-G controller receives acceleration signals indicating G force levels over time, the controller calculates whether the anti-G garment pressure should be increased or decreased and transmits signals to the valve controller to increase or decrease anti-G garment pressure. Increasing the anti-G garment pressure compensates for the airman's loss of tolerance to high G levels immediately after exposure to a period of low or negative G levels.

Abstract: This invention relates to devices for separating oxygen from more complex gasses such as air which contains oxygen, and delivering the separated-oxygen at an elevated pressure for use immediately, or for storage and use later. More particularly, the invention relates to solid state electrochemical devices for separating oxygen from more complex gasses to produce the desired oxygen and delivering the oxygen at elevated pressures up to and exceeding 2000 psig.

Abstract: A ceramic oxygen generator is described which is capable of modular construction to permit the oxygen generation capacity to be expanded. An ionically conducted ceramic electrolyte is formed into a series of rows and columns of tubes on a tube support member and like electrolyte bodies can be connected together to form a manifold therebetween for oxygen produced in the interiors of the rubes. An electrical connection between tubes is formed such that the anodes and cathodes of tubes in a column are connected in parallel while the tubes in the row are, respectively, connected anode to cathode to form a series connection.

Abstract: A pneumatic terminal block assembly worn by a Pilot couples breathing gas from a regulator to the pilot's breathing mask. An emergency breathing gas supply attached to the pilot's seat remains with the pilot during ejection and supplies high pressure breathing gas to an emergency regulator which is part of the terminal block assembly. The emergency regulator on the terminal block is coupled to the emergency breathing gas supply by a small diameter high pressure hose which is not susceptible to tearing or kinking during ejection caused by the blast of oncoming air.

Abstract: An injector mechanism uses breathing system gas to entrain cabin air to demist and defog the hood and visor of an aircrew chemical and biological warfare ("CBW") suit. The injector includes a needle valve for flow rate adjustment and an aneroid for altitude compensation. The CBW filter is downstream of the negative pressure produced by the injector to purify any ambient air drawn into the system at the negative pressure region. Positive pressure in the system downstream of the CBW filter prevents inward leakage and contamination of the demist and defog gas stream.

Abstract: A high altitude G-valve produces a pressure signal in response to altitude and G-load without a connection to an external altitude sensing device. Bleed path pressure regulation by an aneroid valve and a G-sensing valve control a pilot valve which in turn controls a main valve. The main valve provides regulated air to the G-valve outlet in response to the pilot valve. A manually actuated button simulates a high-G load on the G-sensing valve to test the operation of the device.
