Abstract
Abstract 1,036,144. Liquefied gas containers. CONCH INTERNATIONAL METHANE Ltd. May 6, 1963, No. 17834/63. Addition to 981,732. Heading F4P. An extensible sheet of material 1, Fig. 1 (not shown), e.g. stainless steel having an area 6 bounded by non-intersecting corrugations 2-5 extending linearly beyond the enclosed area 6 as claimed in parent Specification 981,732, is thermally insulated by load-bearing material 10, e.g. blocks of open-cell polyvinyl chloride contained in one or more evacuated chambers bounded by the sheet of material 1 and by a further sheet or sheets of material each having a base and spacing walls secured to the sheet 1. Said further sheets form trays 8, 9 having bases 8b, 9b, Fig. 2 (not shown) and sides 8a, 8c, 9a, 9c. Fibre glass and polyurethane foam may constitute the insulation media.
