Abstract: The vent line of a space-borne solid subliming cooler is formed to provide a heat radiator which radiates much of the heat losses otherwise parasitically conducted back to the cooler thereby permitting the use of certain high heat capacity cryogens at operating and working temperatures requiring very low operating vapor pressures but without as much parasitic heat conduction loss as is associated with conventionally vented solid subliming coolers.

Abstract: A support for a cryogen container, particularly adapted for use in spacecraft, provides a dual support. One portion of the structure supports the container in the absence of acceleration force, and the other portion of the structure supports the container in the presence of acceleration forces. The support includes a first connector means and second connector means. A first support extends between the first and second connector means. The first support is constructed of high-strength metal and is adapted at its ends for structural engagement and support of said first and second connector means. A second support also extends between said first and second connector means. The second support is constructed of material having low thermal conductivity, has a degree of elasticity, and provides support of said first connector means from said second connector means in the presence of normal forces imposed by the container and its contents.
