Abstract

Abstract 924,803. Storing liquefied gas. CONCH INTERNATIONAL METHANE Ltd. June 20, 1961, No. 22193/61. Class 8(2). A tank for liquefied gas, e.g. natural gas, nitrogen or helium, comprises a container constructed of dimpled, thin metal sheets surrounded by and supported on load-bearing surfaces which are part of a thermal insulation system, spaces between the outside of the dimples and the load-bearing surfaces being filled with a resilient filler, e.g. polyurethanes and polyvinyl chlorides, particularly of the foamed type, or resin bonded fibres such as glass fibres. As described a prismatic tank has a floor 9 and side walls 7 formed from dimpled stainless steel sheet fixed at 10 and 8, respectively, to plywood panels 5 and 4 which with further plywood panels 6 and 3 are bonded to balsa wood panels 2 and 1 of the insulation system. The corners between the floor and side walls are sealed by gutter-like, transversely corrugated strips 11. The resilient filler is shown as 13 between the floor and side walls 9 and 7 and the plywood panels 6 and 3. The space between the strips 11 and the panels 4 and 5 may also be filled with reslient filler. The metal sheet may, alternatively, be made of aluminium or its alloys or copper or its alloys and the thermal insulation may be quippo, cork, foamed plastics, glass, asbestos, jute fibres, mineral wool or cellular gypsum. The metal sheet may form a barrier round another vessel for the liquefied gas to prevent escape of the gas in case of rupture of that vessel; the dimples on the inside of metal sheet may in this case also be filled with resilient filler. Specifications 919,587, 924,801, 924,802 and 924,804 are referred to.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 117 words
A MEMBRANE TANK FOR CONTAINING FLUIDS AT A TEMPERATURE CONSIDERABLY BELOW AMBIENT TEMPERATURE COMPRISING A CONTAINER CONSTRUCTED OF THIN METAL SHEET PROVIDED WITH THERMAL-STRESS-RELIEVING PROTRUSIONS, AND THUS PRESENTING AN IRREGULAR SURFACE; THERMAL INSULATING MATERIAL HAVING SUBSTANTIALLY NON-RESILIENT LOAD-BEARING SURFACES EXTERNALLY SURROUNDING SAID CONTAINER AND SUPPORTING SAID CONTAINER BY ENGAGEMENT WITH ONLY THOSE PORTIONS OF SAID IRREGULAR SURFACE WHICH PROTRUDE TOWARD SAID INSULATING MATERIAL, SO THAT THERE ARE SPACES IN SOME AREAS BETWEEN THE OUTSIDE OF THE CONTAINER AND THE LOAD-BEARING SURFACES; AND A RESILIENT FILLER SUBSTANTIALLY COMPLETELY OCCUPYING SAID SPACES, SAID FILLER BEING SUFFICIENTLY DEFORMABLE SO AS TO DISTRIBUTE A FLUID LOAD IN SAID TANK, IN A UNIFORM MANNER, FROM SAID METAL SHEET TO SAID LOAD-BEARING SURFACES.
