A cooling apparatus includes a container filled with a quantity of coolant fluid initially cooled to a solid phase, a cooling loop disposed between a heat load and the container. A pump for circulating a quantity of the same type of coolant fluid in a liquid phase through the cooling loop, a pair of couplings for communicating the liquid phase coolant fluid into the container in a direct interface with the solid phase coolant fluid.

Cooling apparatus and couplings therefor

The invention pertains to a measurement system for simultaneously measuring torque and angular flexure in a pressure suit joint. One end of a joint (11) under test is held rigid. A torque transducer (31) is pivotably supported on the other movable end of the joint. A potentiometer (36) is attached to the transducer (31) by an arm (33). The wiper shaft (37) of the potentiometer is gripped by a reference arm (41) that rotates wiper shaft (37) the same angle as the flexure of joint (11). A signal is generated by the potentiometer (36) which is representative of the joint flexure. A compensation circuit (67) converts the output of the transducer (31) to a signal representative of joint torque.

Pressure suit joint analyzer

An improved cooling and ventilating system for removing metabolic heat, waste gases and water vapor generated by a wearer of an hermetically sealed spacesuit. The cooling system is characterized by a body suit having a first circuit for simultaneously establishing a cooling flow of water through the thorax and head sections of the body suit including circulation patches mounted in the thorax section and head section of the body suit, a second circuit for discharging a flow of gas throughout the spacesuit and a disconnect unit for coupling the circuits with a life support system externally related to the spacesuit.

Cooling system for removing metabolic heat from an hermetically sealed

A separable entry closure assembly for joining axially separable tubular segments of a pressure suit along an angulated zone of separation having a first portion projected transversely beneath the axilla zone of the suit and a second portion projected behind the shoulder zone thereof and characterized by a first endless member of a rigid configuration affixed to one segment of the suit, a second endless member of a rigid configuration affixed to the other segment and mated in hermetically sealed relation with the first endless member, and a releasable 'C' section clamp releasably securing the first endless member to the second endless member.

Spacesuit torso closure

An evaporative refrigerator or cooler comprising a bundle of spaced, porous walled tubes closed at one of their ends and vented to a vacuum at the other end is disclosed. The tube bundle is surrounded by a water jacket having a hot water inlet distribution manifold and a cooled water outlet through a plenum chamber. In operation, hot water is pumped into the jacket to circulate around the tubes, and when this water meets the vacuum existing inside the tubes, it evaporates thereby cooling the water in the jacket. If cooling proceeds to the point where water penetrating or surrounding all or part of the tubes freezes, operation continues with local sublimation of the ice on the tubes while the circulating water attempts to melt the ice. Under some conditions, both sublimation and evaporation may take place simultaneously in different regions of the device.
