Abstract 981,732. Extensible metal sheets. CONCH INTERNATIONAL METHANE Ltd. Dec. 11, 1962 [July 27, 1962], No. 28880/62. Heading E1K. [Also in Divisions B3, B7 and F4] An extensible sheet more particularly for containers for storage of liquid gas has an enclosed area 6 bounded by corrugations 1-4 which do not intersect and extend beyond the enclosed area. The corrugations may be of symmetrical or unsymmetrical V-section and extend to the edge of the sheet. There are four corrugations at right angles to one another which form a square area. Sheets with triangular and hexagonal areas are described. In Fig. 5 opposed corrugations 42, 44 and 43, 45 have their crests offset in opposite directions and the enclosed area is in the plane of the crests. Fig. 3 (not shown) is similar to Fig. 5 but the corrugations are not normal to the sides of the square enclosed area. When the sheets are welded together to form a container corrugations meeting at the corners of the container are joined together. A container for storage of liquid gas (see Division F4) in a ship (see Division B7) is described and a method of construction (see Division B3).
A EXTENSIBLE UNITARY, CONTINUOUS, FLUID IMPERMEABLE SHEET INCLUDING AN ENCLOSED AREA BOUNDED ENTIRELY BY NON-INTERSECTING BUT METERING CORRUGATIONS IN THE SHEET, WHICH CORRUGATIONS EXTEND LINEARLY BEYOND THE ENCLOSED AREA, AND WHICH CORRUGATIONS ARE CAPABLE OF FLEXING IN RESPONSE TO THERMAL EXPANSION AND CONTRACTION OF THE SHEET; A SUPPORTING STRUCTURE FOR SAID SHEET, SPACED FROM
