    Abstract: Escaping gas from the 20 percent valve of a compressed liquid gas tank is fed through a metered opening into an expansion chamber. A temperature sensitive element located within the expansion chamber has a first ambient temperature position and a second lower temperature position. The escaping gas normally has the same temperature position. The escaping gas normally has the same temperature as the ambient; however, as the tank is filled beyond the 80 percent volume position, liquid gas is drawn into the expansion chamber where it immediately expands and vaporizes. The expanding process draws heat from the immediate surroundings, thereby lowering the temperature of the expansion chamber and the temperature sensitive element which assumes the second temperature position. Movement of the temperature sensitive element is coupled with a spring-loaded control valve feeding the compressed liquid gas tank, thereby closing the spring-loaded valve and stopping the filling process.

    Abstract translation: 来自压缩液体气罐的20％阀的逸出气体通过计量开口进入膨胀室。 位于膨胀室内的温度敏感元件具有第一环境温度位置和第二较低温度位置。 逸出的气体通常具有相同的温度位置。 逸出的气体通常具有与环境相同的温度; 然而，当罐被填充超过80％体积位置时，液体气体被抽吸到膨胀室中，在那里它立即膨胀和蒸发。 膨胀过程从周围环境中吸取热量，从而降低膨胀室和承受第二温度位置的温度敏感元件的温度。 温度敏感元件的移动与供给压缩液体气罐的弹簧加载控制阀耦合，从而关闭弹簧加载的阀并停止填充过程。

    Abstract: 938,520. Storing liquefied gases. CONTINENTAL OIL CO. March 7, 1962 [March 20, 1961], No. 8818/62. Class 8(2). [Also in Group XXIX] A reservoir for low temperature liquid gas comprises a container 21 suspended within a depression 17 in the ground above its bottom press means 16 which extend between supports 11 secured on at least two sides of the depression. The container 21 is attached to the crossextending I beams 16 by cables or rods with spring hangers 20 which may be omitted at positions near the centre of the tank which are not greatly affected by expansion. The depression 17 is lined with asphalt, plastic or other impervious material and the space 22 between it and the container 21 is filled with insulating material, loose or in bags. A cover 24 of sheet metal, plastic or other material extends over the beams 16 and its edges dip into a peripheral trough 13 which forms a water-seal. The gas mentioned is meltrane.
