Abstract 842,719. Storing gases under pressure. LORENTZEN, H. L. Sept. 13, 1956 [Sept. 16, 1955], No. 28051/56. Class 8(2). A container for a liquefied gas such as methane is insulated by vapour formed from the liquid in passages 3 formed between lamellae 2, of metal, synthetic resin, paper or a woven material with a dark rough surface, stuck to the inner surface of the container wall 1. The axes of the passages 3 may be perpendicular to the wall 1 or oblique as shown and the passages are small in order to hinder the formation of convection currents and may be of circular, square or hexagonal cross-section. In Fig. 2, lamellae are shown which are so corrugated and joined that the main passages 3 are of circular section. Rectangular units of insulation or hexagonal units with frames 5, Fig. 4, may be formed. The passages may have constrictions or be covered with a net. Local groups of cells may intercommunicate. Specification 789,755 is referred to.
