    Abstract: 1,155,116. Liquefied gas storage containers. TECHNIGAZ. 19 Sept., 1966 [22 Sept., 1965], No. 41704/66. Heading F4P. The fluid-tight inner vertical cylindrical shell 13, Fig. 1, of a heat insulated double-walled liquefied gas container and having a top 22 and generally flat bottom 21 is constructed of flexible sheet metal plates welded at their overlapping edges and having a first group of spaced parallel corrugations intersected at right angles by a second group of similar corrugations, and the inner shell is secured at spaced points to the external shell 2 by brackets 47, Fig. 7, extending through the heat insulation 14 between the two shells; the outer cylindrical shell which may be of steel or concrete having a flat bottom 3 resting on a prepared earth base 4. The first group of corrugations 16 of the lateral cylindrical wall 17 of the shell 13 extend continuously and vertically whilst the corrugations 18 of the second group extend round circumference of wall 17. The first group of corrugations of the base 21 comprise alternate radially extending corrugations 23, 23 1 which divide the base into sectors 24 and those sectors on either side of a corrugation 23 1 have further continuous corrugations 25 parallel thereto but of differing lengths and are intersected at right angles by parallel corrugations 26 which form the second group. The roof 22 of shell 13 is similarly constructed and all corrugations project inwardly. The bracket 47 shown in Fig. 7 comprises four radial ribs welded at one end to a steel plate 50 embedded in the concrete wall of shell 2 and secured at the other end of a screw 52 to the shell 13. A modified bracket shown in Fig. 11 comprising a tube 60 welded at its outer end to a steel plate 50 and closed at its inner end by a plate 62 carrying a stud 63 which projects through the shell 13 and secured by a nut 66. The heat insulation 14 comprises panels 58, 59 of rigid expanded polyurethane or expanded polyvinylchloride. A central orifice 28 in the roof of the container is closed by a plate 29 having filler pipes 32 and a manhole 31.
