947,059. Carrying liquefied gases. W. J. GEBIEN. April 25, 1960 [April 30, 1959], No. 14432/60. Heading B7A. [Also in Division F4] A liquid methane storage receptacle 88 operating at substantially atmospheric pressure and constructed of balsa wood 92 lined with redwood 90 is buoyantly supported within a steel tank 86 charged with liquid, e.g. crankcase oil, crude petroleum, palm oil and the like from a reservoir and standpipe unit 96. The oil serves to seep into cracks developing in the receptacle walls and congeal therein, /thus forming a seal against the escape of liquefied gas. In a modification the ship's hull may serve as the oil storage tank and the gas storage receptacle 88a, Fig. 9 (not shown), may be rigidly supported by positioners 106, 108, 110 and 112. |
