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.
