Heat transfer method to preclude ice formation on paving

Claim 1

THE METHOD OF MAINTAINING A GROUND SURFACE COVERED BY A SLAB OF PAVING AT A TEMPERATURE TO PRECLUDE THE FORMATION OF ICE THEREON WHICH COMPRISES POSITIONING A PLURALITY OF CLOSED ELONGATED MEMBERS IN A HORIZONTALLY SPACED RELATIONSHIP, EACH HAVING A PORTION EXTENDING IN AN UPRIGHT DIRECTION BELOW SAID SURFACE WITH THE UPPER END ADJACENT TO AND SPACED BELOW, THE PAVING, POSITIONING SUBSTANTIALLY HORIZONTAL CONDENSATION CHAMBERS IN EMBEDDED RELATION IN THE PAVING IN A NETWORK, WITH THE CONDENSATION CHAMBERS EACH BEING ATTACHED TO ONE OF SAID UPRIGHT-EXTENDING PORTIONS TO COMPLETE THE CLOSED ELONGATED MEMBER, EACH OF SAID MEMBERS BEING PARTIALLY FILLED WITH A MEDIUM IN A LIQUID STATE AND CONVERTIBLE INTO A GASEOUS STATE UPON IMPOSITION OF HEAT IN THE RANGE OF AT LEAST SUBSTANTIALLY 45*F. THERETO AND CONVERTIBLE FROM THE GASEOUS STATE TO THE LIQUID STATE UPON IMPOSITION OF COLD IN THE RANGE OF AT LEAST SUBSTANTIALLY 32* F., THERETO, THE LOWER END PORTIONS OF SAID MEMBERS BEING SUBMERGED BELOW SAID SURFACE TO EXTENT SUCH AS TO LIE BELOW THE FROST LINE OF THE SUBTERRANEAN EARTH, THE LIQUID MEDIUM IN THE LOWER END PORTIONS OF SAID MEMBERS BEING SUBJECTED TO THE HEAT OF ADJACENT REGIONS OF THE SUBTERRANEAN EARTH TO THEREBY GASIFY SOME OF SAID MEDIUM AND CAUSE THE MEDIUM CONVERTED TO THE GASEOUS STATE TO BE EVOLVED FROM THE LIQUID MEDIUM AND FLOW INTO THE CONDENSATION CHAMBER OF SAID MEMBERS, THE MEDIUM IN THE GASEOUS STATE WHEN IN THE CONDENSATION CHAMBERS OF SAID MEMBEERS BEING SUBJECTED TO THE COLD OF THE ADJACENT PAVING TO THEREBY CONDENSE THE MEDIUM IN THE GASEOUS STATE AND BE RETURNED TO AND ABSORBED IN THE RESPECTIVE LIQUID MEDIUMS TO HEAT THE PAVING TO THE TEMPERATURE TO PRECLUDE FORMATION OF ICE.

Claim 2

THE METHOD OF MAINTAINING A GROUND SURFACE COVERED BY A SLAB OF PAVING AT A TEMPERATURE TO PRECLUDE THE FORMATION OF ICE THEREON WHICH COMPRISES POSITIONING A PLURALITY OF CLOSED ELONGATED MEMBERS IN A HORIZONTALLY SPACED RELATIONSHIP, EACH HAVING A PORTION EXTENDING IN AN UPRIGHT DIRECTION BELOW SAID SURFACE WITH THE UPPER END ADJACENT TO AND SPACED BELOW, THE PAVING, POSITIONING SUBSTANTIALLY HORIZONTAL CONDENSATION CHAMBERS IN EMBEDDED RELATION IN THE PAVING IN A NETWORK, WITH THE CONDENSATION CHAMBERS EACH BEING ATTACHED TO ONE OF SAID UPRIGHT-EXTENDING PORTIONS TO COMPLETE THE CLOSED ELONGATED MEMBER, EACH OF SAID MEMBERS BEING PARTIALLY FILLED WITH A MEDIUM IN A LIQUID STATE AND CONVERTIBLE INTO A GASEOUS STATE UPON IMPOSITION OF HEAT IN THE RANGE OF AT LEAST SUBSTANTIALLY 45*F. THERETO AND CONVERTIBLE FROM THE GASEOUS STATE TO THE LIQUID STATE UPON IMPOSITION OF COLD IN THE RANGE OF AT LEAST SUBSTANTIALLY 32* F., THERETO, THE LOWER END PORTIONS OF SAID MEMBERS BEING SUBMERGED BELOW SAID SURFACE TO EXTENT SUCH AS TO LIE BELOW THE FROST LINE OF THE SUBTERRANEAN EARTH, THE LIQUID MEDIUM IN THE LOWER END PORTIONS OF SAID MEMBERS BEING SUBJECTED TO THE HEAT OF ADJACENT REGIONS OF THE SUBTERRANEAN EARTH TO THEREBY GASIFY SOME OF SAID MEDIUM AND CAUSE THE MEDIUM CONVERTED TO THE GASEOUS STATE TO BE EVOLVED FROM THE LIQUID MEDIUM AND FLOW INTO THE CONDENSATION CHAMBER OF SAID MEMBERS, THE MEDIUM IN THE GASEOUS STATE WHEN IN THE CONDENSATION CHAMBERS OF SAID MEMBEERS BEING SUBJECTED TO THE COLD OF THE ADJACENT PAVING TO THEREBY CONDENSE THE MEDIUM IN THE GASEOUS STATE AND BE RETURNED TO AND ABSORBED IN THE RESPECTIVE LIQUID MEDIUMS TO HEAT THE PAVING TO THE TEMPERATURE TO PRECLUDE FORMATION OF ICE.
