Abstract: An improved gas separation vessel apparatus is provided. The gas separation vessel apparatus is adapted to separate oxygen and other process gases, and it employs both vertically-, or alternatively, horizontally-positioned vessels. The gas separation vessels disclosed contain removable radial-flow bed cartridge-type adsorbent subassemblies, which may be replaced, substituted, or serviced with minimal system down time.

Abstract: A power cogeneration system employing a partially-open gaseous fluid cycle method and apparatus devices for oxy-fuel combustion conversion of a given hydrocarbon composition fuel's heat-value energy into mechanical or electrical power energy, and transferred useful heat energy, with accompanying large reductions of consumed fuel and undesirable exhaust emissions.

Abstract: A partially open fired heater regenerative cycle, wherein the fired industrial type heater cycle's heat transfer fluid replaces the air predominant nitrogen heat transfer fluid employed in a conventional air/fuel combustion heater, is disclosed. The heater cycle's method and apparatus are susceptible to providing a significant percent mass flow reduction of fugitive nitrogen oxide and carbon monoxide mass flow emissions as emitted by current art Low-NO.sub.x art heaters on a rated per million Btu per hour basis, and is further capable of developing exceptionally high steady-state heat transfer system cycle thermal efficiencies.

Abstract: A system to produce a densified fluid, and more particularly a densified propellant to be used in a launch vehicle. The system includes a vessel containing a first fluid and an injection nozzle to inject a cooling fluid into the vessel. The first fluid in the vessel has a freezing temperature greater than the boiling point of the second fluid that is injected into it. The second fluid is injected into the first fluid and evaporates therefrom to cool the first fluid. An anti-icing chamber is placed around the injection nozzle and a third fluid is provided to the anti-icing chamber to form an interface which does not allow the first fluid to contact the injection nozzle. In this way, the second fluid can be substantially continuously provided through the injection nozzle to the first fluid to cool the first fluid. A heat exchanger can then be provided in the vessel to cool an additional material.

Abstract: A fuel preheater for liquid fuel having a multi-pass heat exchanger for said fuel, heated by an electrical resistance heater provided with a sensor adjacent the device designed to burn the fuel, the sensor controlling the flow of electrical current to said heater. The heat exchanger is preferably made from extruded stock and a material having good heat conductivity. If the device burning the fuel is a water cooled device, a separate heat exchanger using such heated water may be placed in series with the preheater in order to augment it.
