    Abstract: 967,753. Storing liquefied gas. GAZ DE FRANCE. July 26, 1961 [Aug. 10, 1960], No. 27165/61. Heading F4P. A liquefied gas storage chamber 3 is excavated from a pit 2 dug in the ground and water is injected around the chamber during the filling thereof with liquefied gas to form about the chamber a layer of frozen water or of a watersoaked and frozen material. An inspection plate 5 is supported in a circular recess 4 in the pit 2 and piping 6, 7 and 8 for removing fluid from the chamber extends through the plate 5. Holes 9, 10, 11 and 12 are provided for injecting the water; the lower ends of the holes may lie close to the pit 2 and the chamber 3. Heat probes 13, 14 and 15 may be provided so that the temperature of the ground may be taken. A layer of sand or loose rocks or stones is disposed on the'plate 5, and this layer may be sprinkled with water so that it will freeze and form a fluid-tight seal. The water is preferably injected when the chamber walls are at a temperature below 32‹ F.
