Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
160 words
IN AN IMPROVED VESSEL FOR BULK TRANSPORTATION OF LIQUID SUCH AS METHANE WHICH BOIL AT TEMPERATURE SUBSTANTIALLY BELOW O*F., WHICH VESSEL INCLUDES A INSULATED TANK SURROUNDED BY THERMAL INSULATION SPACE BOUNDED BY AN INNER LINER IMPERVIOUS TO SAID LIQUID AND OUTER SHELL SPACED FROM SAID LINER, SAID SHELL AND LINER CONSTITUTING BOUNDARIES AND BEING SUBJECT TO RELATIVE MOVEMENT TO VARY THE INSULATION SPACE VOLUME, THE COMBINATION WHICH COMPRISES A MULTIPLE LAYER INSULATION IN SAID SPACE BETWEEN SAID SHELL AND LINER WITH A RESILIENT FIBROUS INNER INSULATION MATERIAL LAYER NEXT TO SAID LINER AND SURROUNDED BY AN OUTER BODY OF RELATIVELY NON-RESILIENT INSULATING MATERIAL WHICH HAS A TENDENCY TO SETTLE BY GRAVITY ON RELATIVE MOVEMENT OF SAID BOUNDARIES, AND PLURAL MEANS AFFIXED TO ONE OF SAID BOUNDARIES PROJECTING INTO THE SPACE OCCUPIED BY SAID RELATIVELY NON-RESILIENT MATERIAL TO INHIBIT SAID SETTING BY GRAVITY, THE QUANTITY OF NON-RESILIENT MATERIAL BEING SUFFICIENT TO APPLY AN ELASTIC COMPRESSION FORCE TO THE RESILIENT FIBROUS MATERIAL.
