Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
133 words
IN A FLUID STORAGE VESSEL OF THE TYPE IN WHICH AN INSULATION COMPRISING A PLURALITY OF RADIANT HEAT BARRIER LAYERS IS WRAPPED ABOUT AN INNER WALL WHICH DEFINES THE STORAGE VOLUME OF SAID VESSEL AND WHEREIN A SPACE BETWEEN SAID INNER WALL AND AN OUTER WALL IS EVACUATED, THE COMBINATION COMPRISING: CONDUIT MEANS EXTENDING THROUGH SAID VACUUM SPACE FROM SAID INNER WALL TO SAID OUTER WALL; MEANS FOR CONNECTING SAID CONDUIT MEANS TO SAID STORAGE VOLUME; SAID CONDUIT BEING CONTINUOUSLY SPIRALLY WRAPPED BETWEEN SUCCESSIVE RADIANT HEAT BARRIER LAYERS AS SAID CONDUIT APPROACHES SAID OUTER WALL; AND MEANS FOR DIVERTING AT LEAST PART OF THE FLOW OF GAS FROM SAID STORAGE VOLUME TO SAID OUTER WALL AFTER SAID GAS PASSES BETWEEN ONLY THOSE RADIANT HEAT BARRIER LAYERS WHICH ARE NEARER TO SAID INNER WALL.
