  • System for venting cryogen from a cryostat
    Patent number: 5117640
    Abstract: A system is provided for controllably venting cryogen of extremely low temperature from a cryostat, wherein a conduit formed of selected metal provides a path of flow for the cryogen from the cryostat to an exhaust system. A gauge is coupled to the conduit, along the path of flow, by means of a bushing which thermally isolates the gauge from the metallic conduit, which is at an extremely low temperature. Thus, the gauge, which is used to continually monitor cryogen pressure, does not become unreadable due to icing or frosting as a result of heat loss from the gauge to the conduit. The bushing is formed from a material such as GC-10, and includes an intermediate portion for spacing the bushing away from the metallic conduit, and also for enclosing a dead space which substantially reduces heat transfer directly between the gauge and cryogen in the conduit.
