Abstract
Abstract AN INSULATION PROVIDES A GAS INSULATING LAYER BETWEEN THE WALLS OF A CONTAINER AND LIQUID HAVING A LOW BOILING TEMPERATURE IN THE CONTAINER. THE INSULATION COMPRISES A PLURALITY OF PANELS MOUNTED ON THE WALLS OF THE CONTAINER. EACH OF THE PANELS COMPRISES A HONEYCOMB STRUCTURE DEFINING A PLURALITY OF CELLS FOR MAINTAINING A GAS COLUMM BETWEEN A PLURALITY OF CELLS FOR MAINTAINING AND THE LIQU ID. A COVERING CLOSES THE END OF THE CELLS ADJACENT THE LIQUID AND HAS AN OPENING THEREIN FOR PROVIDING A STABLE CAPILLARY GAS-LIQUID INTERFACE THEREIN BETWEEN GAS IN THE CELL AND LIQUID IN THE CONTAINER. MEANS IS PROVIDED FOR SECURING THE PANELS TO THE CONTAINER FOR PROVIDING A SEAL THEREBETWEEN TO BLOCK THE FLOW OF THE LIQUID BETWEEN THE PANELS AND INTO CONTACT WITH THE WALLS OF THE CONTAINER. A RIGHT ANGLE JOINT IN THE INSULATION IS PROVIDED AT RIGHT ANGLES OF THE CONTAINER AND WHICH EFFECTIBVELY BLOCKS FLOW OF LIQUID INTO CONTACT WITH THE CONTAINER WALLS THEREAT. D R A W I N G
