    Abstract: An integrated membrane-type tank container for cryogenic liquids, supported within a rigid outer shell, is made up of a multiplicity of panels in the form of shallow boxes of thin, flexible metal sheet material filled with load-bearing insulation, and sealingly connected together by edge extensions of their front and back faces respectively to provide inner and outer impervious membrane walls, which walls are attached to a support framework carried by the rigid outer shell. The edge extensions of adjacent panels are welded together through metal strips folded to provide expansion joints and the shallow boxes are attached to the framework through these strips. The framework is provided with brackets for adjusting the spacing of individual frame members from the outer rigid shell to facilitate even alignment of the shallow boxes.

    Abstract translation: 用于低温液体的集成的膜式容器容器，其被支撑在刚性外壳内，由多个薄板形式的薄的薄的柔性金属板材料形成，填充有承载绝缘体，并密封地连接在一起 通过它们的前表面和后表面的边缘延伸部分以提供内部和外部不可渗透的膜壁，该壁附接到由刚性外壳承载的支撑框架。 相邻面板的边缘延伸部通过折叠的金属条焊接在一起，以提供伸缩接头，浅层通过这些条连接到框架上。 该框架设置有用于调节单个框架构件与外部刚性壳体的间隔的支架，以便于浅盒子的均匀对准。

    Abstract: 1,141,219. Cold separation of gas mixtures. CONCH INTERNATIONAL METHANE Ltd. 8 Aug., 1967 [17 Aug., 1966], No. 36252/67. Heading F4P. Natural hydrocarbon gas is supplied to a distribution system at a controlled B.T.U. value by liquefying a feed stream 2 at a pressure higher than the distribution pressure in indirect heat exchangers 5, 6, 7 cooled by an external refrigerant, diverting through a line 23 a minor portion of the high pressure L.N.G. leaving exchanger 7, expanding it at a valve 24 into a vessel 27 to produce flash gas and liquid heavy hydrocarbons, expanding at valves 42, 46, 51 the remainder of the L.N.G. into a storage vessel 52 maintained at about atmospheric pressure expanding at a valve 31 the hydrocarbon liquid withdrawn from vessel 27 and adding it to boil-off gas withdrawn by a pump 53 from vessel 52 at a rate controlled by a calorimeter 34a and passing the mixture so formed through a line 47a and a compressor 48 to an outlet line 33 leading to the distribution system. L.N.G. leaving expansion valve 42 is joined by flash gas from chamber 27 and is further cooled in an exchanger 21 traversed by a reverse flow of said boil-off gas and heavy hydrocarbon liquid and also by a reverse flow of a minor portion of L.N.G. withdrawn from the outlet line of exchanger 21 and expanded at a valve 43. The main body of L.N.G. is still further cooled in an exchanger 10 traversed by a reverse flow of a minor portion of L.N.G. leaving expansion valve 46. The two reverse flows of expanded L.N.G. are warmed in exchangers 5, 6, 7 and are fed to the outlet line 33. The external refrigerant for cooling exchanger 5, 6, 7 is circulated in a closed cycle comprising a surge tank 9, expansion valves 11, 21, 22 in series and a three stage compressor to which refrigerant vapour leaving exchangers 5, 6, 7 is fed and which delivers to the tank 9. A portion of liquid refrigerant is withdrawn from exchanger 6 and is used to heat a coil 36 in flash vessel 27; the so-cooled refrigerant being returned to exchanger 7.
