Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
135 words
A ONE-WAY HEAT FLOW PANEL IN WHICH HEAT FLOW IS CONTROLLED BY A VARIATION OF THE EMISSIVITY OF AN INNER SURFACE, SAID PANEL COMPRISING IN COMBINATION A SUPPORTING EDGE STRUCTURE AND TWO OPPOSING SHEETS MOUNTED ON THE EDGE STRUCTURE TO FORM A SEALED ENCLOSURE, THE FIRST OF SAID SHEETS HAVING A HIGHLY-POLISHED METALLIC INNER SURFACE HAVING AN EMISSIVITY LOWER THAN ABOUT 0.5, THE SECOND OF SAID SHEETS HAVING AN INNER SURFACE HAVING AN EMISSIVITY HIGHER THAN THAT OF THE INNER SURFACE OF SAID FIRST SHEET, SAID ENCLOSURE CONTAINING A SMALL AMOUNT LESS THAN 1% BY VOLUME OF SAID ENCLOSURE OF INERT LIQUID BOILING IN THE RANGE OF 80*-120*C., WHEREBY SAID LIQUID DEPOSITS ON SAID POLISHED METALLIC INNER SURFACE WHEN SAID SURFACE IS COOLER THAN THE SURFACE ON THE OPPOSING SHEET, THUS INCREASING THE EMISSIVITY THEREOF.
