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). |
