Abstract: 970,152. Storing liquefied gases. UNION CARBIDE CORPORATION. Sept. 12, 1963 [Oct. 24, 1962], No. 35907/63. Heading F4P. A rectangular low temperature storage container comprises an outer jacket 12 composed of a solid core 21 of heatinsulating material encased in outer and inner stainless steel sheets 22a, 22b separated by an evacuable insulation space 20 from an inner vessel 14 suspended by a neck tube 16 secured to the top portion of the inner metallic sheet 22b, the neck tube being fitted with a heat insulated rectangular cover 62 (Fig. 2). The walls of the inner vessel 14 are made of relatively flexible metal sheeting reinforced by a plurality of metal partitions 30 intersecting each other to thereby divide the inner vessel 14 into a plurality of compartments closed by a sliding cover or covers 34, 36. Each wall of the outer jacket 12 is provided with bevelled edges 24a, 24b by which it is welded to an adjacent wall. The evacuable space 20 contains alternate layers of heat insulation material 56, e.g. glass wool or fibre glass sandwiched between metal, metal oxide or metal coated material. The solid core 21 of the -outer jacket 12 is preferably made of plywood, plain wood, compressed fibreboard laminate or a metallic honeycomb structure. The neck tube 16 is comprised of metal or reinforced fibrous laminate impregnated with a phenolic or an epoxy resin. The cover 62 may be vacuum insulated or comprise, as shown, a top metal sheet 64 bonded to a laminate of layers of polyurethane foam 66 alternating with aluminium sheets. To maintain the vacuum in the space 20 an absorbent 70 may be provided.
