Abstract: In a diver heating system of the type in which a fluid being circulated in he circulation passage of the diver's clothing is heated by the controlled combustion of a reducing metal in an oxygen atmosphere, a temperature control system in which a gas flow control valve controls the oxygen flow to the reaction to automatically maintain a preset temperature of the circulating fluid and a gas shut-off valve serves as a backup to quickly shut-off the oxygen flow if the temperature of the circulating fluid exceeds a preset value. In both the gas flow control valve and the gas shut-off valve, the heated water is fed through a heat exchanger where it is in thermal contact with a thermofluid so that heat is transferred between the two fluids. The change in volume of the thermofluid with temperature is coupled to a motion bellows which operates to control the flow of oxygen through an orifice.

Abstract: Supercorroding magnesium alloys that operate like galvanic cells and react apidly and predictably with seawater to produce heat and hydrogen gas. The alloys are formed by a mechanical process that bonds magnesium and noble metal powder particles together in a strong electrical and mechanical bond. The alloy powders can be compacted and sintered to form barstock, etc., suitable for making self-destructing corroding links.

Abstract: Supercorroding magnesium alloys that react rapidly and predictably with seawater to produce heat and hydrogen gas. The alloys are formed by a mechanical process that bonds magnesium and noble metal powder particles together. The alloy powders can be sintered to form barstock, etc., suitable for self-contained corroding links.

Abstract: An electro-mechanical, low backlash cable connector having a plurality of ring washers disposed within a connector housing. A plurality of spacer washers disposed between each pair of spring washers imparts independent operation to each spring washer and translates shear forces from the entering cable to the connector housing. Both the spring washers and the spacer washers are disposed at an inward angle from the connector housing opening. Such angular disposition allows a cable to freely enter the connector housing. However, upon attempting to withdraw the cable, the spring washers bite into the cable thereby preventing its egress.
