Abstract 951,923. Laminates. CONCH INTERNATIONAL METHANE Ltd. Jan. 28, 1963 [March 12, 1962], No. 3468/63. Heading B5N. [Also in Divisions B7 and F4] A container for liquefied gas comprises a rigid shell 13 lined with heat insulating panels 3, 4, the edges of adjacent panels being shaped so that there is a gap between adjacent panels widening in the direction of the inner surface of the panels, the gap being filled with a sealing material 28, e.g. polyvinyl chloride foam compressed to at least 90% of its free volume, and being closed by a thin scab 16, e.g. of plywood or maple glued in position. The panels 4 are formed of a honeycomb core 20 filled with foamed-in-place polyurethane and faced with plywood 21 and 22 which is bonded to the core 20, and the panels 3 are formed of a balsa wood core 23 faced with plywood 24 and 25 bonded to the core 23.
A CONTAINER FOR STORING A LIQUID AT A LOW TEMPERATURE, IN PARTICULAR FOR STORING LIQUEFIED METHANE AT ABOUT ATMOSPHERIC PRESSURE, COMPRISING A RIGID SHELL INTERNALLY LINED WITH HEAT-INSULATING PANELS SPACED FROM THE INNER SURFACE OF THE RIGID SHELL, A TANK LOCATED WITHIN THE HEATINSULATED RIGID SHELL, FIXING STRIPS SECURED TO THE INNER SURFACE OF THE SHELL, THE OUTER EDGE OF EACH PANEL BEING BONDED TO THE INNER SURFACE OF A FIXING STRIP IN SUCH A WAY THAT ADJACENT PANELS ARE INTERCONNECTED BY SAID FIXING STRIP, EACH PANEL BEING MOREOVER KEPT IN PLACE BY STUDS SECURED TO THE INNER SURFACE OF THE SHELL AND LOCATED BETWEEN THE FIXING STRIPS, A GAP WIDENING IN THE DIRECTION OF THE INNER SURFACE OF THE PANELS BEING PRESENT BETWEEN ADJACENT PANELS, SAID GAP BEING FILLED WITH A SEALING MATERIAL AND BEING CLOSED BY A THIN SCAB.
