Abstract 989,599. Storing liquefied gases. LINDE'S EISMASCHINEN A.G. GES FUR. Nov. 1, 1963 [Nov. 2, 1962], No. 43163/63. Heading F4P. A storage container 1 for liquefied gas has composite walls of welded construction formed from at least two parallel aluminium, aluminium alloy or synthetic weldable material sheets, spaced apart by a distance of from 20- 300 mm. and connected by rib-like spacing members 3 interposed between the sheets at regular intervals. The composite walls, Fig. 1, are formed from a plurality of extruded sections 2 connected together by butt-welds 4, each section consisting of parallel flanges joined together by at least one spacing member 3. The edges of the inner sheets are connected by strips 5 arranged at 45 degrees and the outer sheets by rounded strips 6, the strips 5, 6 being connected by longitudinal members 7, alternatively (Fig. 7, not shown) the edges and corners may be constructed from extruded sections. The container has a dome 11 for vaporized gas and is reinforced by cross-walls 8, 9. The outer sheets may be provided with a layer of heat-insulating material or a vacuum jacket (not shown). In an alternative construction (Fig. 6) the walls comprise three parallel sheets 20, 25, 21 separated by perpendicularly arranged corrugated sheets 26 roller welded, spot welded or soldered thereto. The cells formed within the composite walls between adjacent spring members are sealed individually or in groups, each cell or group of cells being provided with a connection for inert gas.
A RECEPTACLE FOR THE TRANSPORTATION AND STORAGE OF LOW-BOILING-POINT LIQUEFIED GASES INCLUDING METHANE AND THE LIKE, COMPRISING: A UNITARY LIQUID-TIGHT CONTAINER OF GENERALLY PRISMATIC CONFIGURATION HAVING A PLURALITY OF WALLS EACH CONSTITUTED OF AT LEAST TWO SPACED-APART PARALLEL METALLIC WALL MEMBERS, AND A PLURALITY OF METALLIC WEBS RIGIDLY SECURED TO SAID MEMBERS AND SPANNING THE SPACE BETWEEN THEM WHILE SUBDIVIDING SAID SPACE INTO A MULTIPLICITY OF INDIVIDUAL FLUID-TIGHT CELLS COLLECTIVELY EXTENDING OVER SUBSTANTIALLY ALL OF THE WALLS OF SAID CONTAINER; A RESPECTIVE PIPE CONNECTION COMMUNICATING WITH EACH OF SAID CELLS FOR INTRODUCING AN INERT GAS INTO EACH OF SAID CELLS; AND A LAYER OF THERMALLY INSULATING MATERIAL OVERLYING THE OUTERMOST ONE OF SAID WALL MEMBERS OF EACH OF SAID WALLS FOR PREVENTING THE TRANSFER OF HEAT TO SAID WALLS AND BY SAID WALLS TO THE CONTENTS OF SAID UNITARY CONTAINER.
