Abstract: A system and method are disclosed for processing an oxygen-containing gas for use in a chemical process producing a generally inert gas. A fluid handling rotor is carried by a rotary shaft for effecting a pressure change in the oxygen-containing gas. A housing surrounds the rotor and the adjacent portion of the shaft. A bearing, axially spaced from the rotor, supports the shaft in the housing for rotation. Lubricant is injected into the bearing and is caused to flow through the bearing and axially toward the rotor. A seal surrounds the shaft intermediate the rotor and the bearing and seals between the shaft and housing. A generally inert seal gas is extracted from the products of the chemical process and injected into the seal under a pressure greater than the pressures within the housing on either side of and immediately adjacent the seal.

Abstract: Apparatus and system for producing coal gas from coal, air and water. Pulverized coal is introduced into a rising stream of air and steam in a retort to constitute a fluidized or entrained bed. The coal reacts with the steam and air to form a gas consisting of hydrogen, carbon monoxide, carbon dioxide, nitrogen, methane and higher hydrocarbons. In some cases the air may be eliminated to produce nitrogen-free gas. In other instances, the production of methane and higher hydrocarbons may be suppressed to produce a gas consisting primarily of hydrogen and carbon monoxide. The retort is constructed so that product gas and air may be burned in an annular space surrounding the central reaction column to produce hot flue gas. Steam tubes may be disposed in the annular space so that the steam and air introduced to the central reaction chamber may be super-heated by the hot flue gas. A further annular space or "wet wall" may be provided surrounding the first annular space through which the intake water is passed, so that the intake water may be brought to a boiling point and converted to steam prior to its being introduced into the steam superheating tubes. This construction causes the walls to the retort to be maintained at a higher temperature than the reaction inside the column, so that all the heat radiated from the walls of the reaction column is directed inwardly, and no heat is lost through the walls. The product gas from the retort is then cooled and passed through a water spray which cools the gas to nearly room temperature, and removes all the fly ash and other particulate matter from the gas.

Abstract: A hypersonic ram jet engine is provided which may be of the hydrogen fueled type and in which static and acceleration thrusts are provided as inherent features of the engine to accelerate the aircraft to speeds at which the ram jet engine can operate efficiently. The static and acceleration thrust is provided by the ram jet engine itself; this being achieved by injecting a secondary airflow into the engine at high pressure by the use of the engine''s liquid hydrogen fuel to condense secondary air, as will be described.

Abstract: An aircraft pitch control system which includes a movable tail composed of a powered stabilizer which is angularly movable about a first axis, and elevators mounted on the rear end of the stabilizer which are angularly rotatable about a second axis displaced from the first axis. The stabilizer is controlled by an electric, pneumatic or hydraulically powered actuator, and the elevators are controlled manually through appropriate cables or mechanical linkage. The stabilizer actuator is controlled by movements of the elevators through an appropriate servo mechanism, so that angular movement of the stabilizer follows angular movement of the elevators. In the event of failure of the stabilizer actuator, the stabilizer is locked in a selected position by an automatic lock, and the pitch of the aircraft is controlled manually by the elevators alone.
