    Abstract: 924,755. Storing liquefied gas. UNION CARBIDE CORPORATION. June 2, 1961 [June 9, 1960], No. 19917/61. Class 8(2). An apparatus for storing and dispensing liquefied gas comprises an inner vessel 10 surrounded by an outer shell 15 within which the vessel 10 is supported by two axially aligned cylinders 20, 21 each extending across an insulation space 18 between the vessel 10 and the shell 15 and having one end disposed in a socket 22 or 23 and the other end disposed within one of the ends of a metal tube 26. The insulation space 18 is preferably subject to a low vacuum pressure and filled with insulating powder of small particle size and containing a pacifying material in the form of metal flakes. Alternatively, the space 18 may be filled with multiple alternate layers of fibre mat and polished metal foil wrapped about the inner vessel 10. The cylinder 20 is fixed in the socket 22 and the adjacent end of the tube 26, the other cylinder 21 not being so fixed to allow for expansion and contraction. The cylinders 20 and 21 are preferably made from reinforced plastic material, e.g. a glass reinforced epoxy resin. The tube 26 is filled with an absorbent material such as silica gel or certain molecular sieve calcium zeolites retained by screens 35 and in communication with the insulation space 18 through holes 29 in the cylinders 20 and 21, for example, so that when subject to the stored gas temperature the absorbent material will absorb traces of gas or vapours from the insulation space. Conduits 30 and 32 are provided for filling and emptying the vessel 10, the conduits being coiled or looped within the insulation space 18 to reduce heat conduction along the conduits. The cylinders 20, 21 may be filled with porous insulating material such as glass wool, glass fibre packing or alternate disks of metal foil and glass fibre mat. The outer shell 15 is mounted on a skid frame 37 connected to the shell through rubber shock mountings 40. The inner vessel and outer shell may be spherical. In a second embodiment, Fig. 3, an inner vessel 110 is supported within an outer shell 115 by cylinders 120, 121. The cylinder 120 has one end secured in a socket 122 provided with a removable cover 50 for renewing absorbent material 127 which is contained in a tubular chamber 54, the latter being welded to a tube 51 within which is secured the other end of the cylinder 120. The cylinder 121 has one end secured in a socket 123 and the other end slidably carried in a tube 60 through which pass filling and emptying conduits 65, 66. The outer shell 115 is mounted on a wheeled carriage. Liquid gas is normally delivered from the vessel 10 under its own vapour pressure but the gas may be put under pressure by external means, e.g. a supply of the same gas as that being stored.
