Abstract: A life support system for an undersea habitat which derives oxygen directly from the sea without connection to shore or supply ships. Dissolved gases, including oxygen and nitrogen, are derived by liquid-to-liquid extraction from a stream of sea water. The gas-loaded solvent is first stripped of nitrogen, and then oxygen, in successive rectification processes, the oxygen passing into the habitat. Exhaust gas from the habitat is partially purified by passing it through fresh solvent, for absorption of carbon dioxide, after which it is recirculated in the habitat. The solvent, containing essentially nitrogen and carbon dioxide, is again contacted by gas-stripped sea water, which reabsorbs the carbon dioxide and nitrogen, and returns to the sea.

Abstract: Heat for maintaining operating pressure in a single phase cryogenic fluid at or above the critical pressure is provided by controllably circulating a portion of the warmed delivery fluid in heat exchange with the storage fluid. The circulated delivery fluid is reheated and recombined with the remainder of the delivery fluid. A regulator device having a double acting valve element movable between two opposite positions controls flows respectively to a pressurizing heat exchanger coil and to a bypass leading directly to delivery.
