Containers for cryogenic liquids and gases

Abstract

Abstract 953,272. Storing liquefied gases. BENDIX CORPORATION. July 5, 1962 [July 13, 1961], No. 25869/62. Heading F4P. A container 10 for gases, particularly liquefied gases such as oxygen or hydrogen, comprises an inner vessel 16 surrounded by but spaced from an outer vessel 11, the inner vessel being mounted within the outer vessel by a pair of conduits 25, 29, each carrying a plurality of heat insulating spacers 30, 31 and 32, the latter having dimensions such that at ambient temperature they engage both vessels whereas when the inner vessel contains the gas and is cooled thereby the area of engagement of the spacers is reduced or some of the latter are disengaged from at least one of the vessels. The conduits provide communication between the outside of the container and the inner vessel 16 and the space between the vessels is evacuated or contains insulation material. The spacers are preferably made of plastic materials such as trifluorochloroethylene and tetrafluoroethylene and the vessels 16 and 11 are made of stainless steel. The spacers are retained by rings 35 fastened to the conduits 25, 29 and the conduit 29 is extended by a tube 36 providing communication to the bottom of the inner vessel. The conduits 25, 29 may extend vertically.
