    Abstract: 932,197. Storing liquefied gases. UNION CARBIDE CORPORATION. Dec. 14, 1961 [Dec. 21, 1960], No. 44778/61. Class 8(2). Apparatus for storing a low-boiling-point liquefied gas, e.g. helium, hydrogen, neon, comprises an inner vessel 10 for storing the gas and an outer shell 16 surrounding the inner vessel with an insulation space therebetween, the vessel and shell being e.g. vertically mounted, the gas space of the inner vessel being connected to the atmosphere, and a thermal shield 11, of e.g. metal, disposed around the inner vessel and cooled by the passing vapour e.g. through flattened vapour conduit 21a direct to the bottom of the vessel 10 and through flattened coils 22a of extension vapour conduit 22 which may be attached to the surface of the shield. The insulation space is filled with e.g. alternate parallel layers of a heat reflective foil such as aluminium separated by submicron glass fibre paper or mat, or with equal parts by weight of copper flakes and finely divided silica. The inner vessel is filled, and discharged, through a conduit 31, which is preferably attached to a helical conduit 32 terminating in a valve 33 covered by a cap 34. The conduit 22 may be directed through a re-entrant tube 19 and pass via a safety valve 25 and bursting disc 26 and a hand valve 28 to atmosphere. The shield 11 may be supported by a hollow support member 17 and connecting means 17a, the upper portion of the member 17 being supported by radial curved arms 18. The inner vessel 10 is supported by spacers 12 and 14, of e.g. reinforced plastic such as melamine of epoxy base resin with a reinforcing material such as glass fibres added, which are rigidly attached to the vessel 10 and the shield 11, and the spacers 14 may be radially fixed to a support pin 14a, and a support ring 15 of e.g. austenitic stainless steel. Absorbent material such as silica gel or sodium zeolite A is located in an enclosure 36 attached to the bottom of the vessel 10 to assist in preserving the low vacuum pressure between the vessel 10 and the shield 11. Alternatively, the apparatus may be mounted horizontally and the shield may be laterally supported by the insulation. Specifications 853,584 and 853,585 are referred to.

    Abstract: 864,685. Storing liquefied gases. CONCH INTERNATIONAL METHANE Ltd. June 23, 1959 [July 1, 1958 ; July 7, 1958], No. 21451/59. Class 8(2). A liquefied gas e.g., methane storage tank 14, Fig. 1, is lined with a plurality of downwardly inclined spaced superposed louvres 36 each overlapping the upper end portion of the adjacent lower louvre so as to provide vapour pockets 38 adjacent the vertical wall 16 of the tank which may be of circular or rectangular cross-section having its bottom 18 lined with cork or aerogel heat insulating material 40 in which are embedded metal pans 20 having upturned rims 28 extending between the lowermost louvres 36. Thermal expansion of the louvres is accommodated by a plurality of radially extending circumferentially spaced corrugations. In a modification the lower ends of louvres 36 Fig. 14 have skirts 110 which assisted by baffles 118 serve to support heat insulation material 112 held in porous bags 114.
