Claim 1

A PROCESS FOR REGULATING THE TRANSFER OF HEAT BETWEEN TWO BODIES SO AS TO MAINTAIN PRESELECTED TEMPERATURE CONDITIONS AS BETWEEN THE TWO BODIES BY UTILIZING A THERMOELECTRIC ASSEMBLY HAVING A PLURALITY OF DISSIMILAR THERMOELECTRIC ELEMENTS ELECTRICALLY CONNECTED TO PROVIDE A PLURALITY OF HOT JUNCTIONS IN ONE BODY AND A PLURALITY OF COLD JUNCTIONS IN THE OTHER BODY UPON THE PASSAGE THERETHROUGH OF ELECTRIC CURRENT IN A PREDETERMINED DIRECTION; AND COMPRISING THE STEPS OF DETERMINING A DEVIATION FROM SAID PRESELECTED TEMPERATURE CONDITIONS REQUIRING SUCH A HEAT TRANSFER BETWEEN SAID TWO BODIES SO AS TO RESTORE SAID PRESELECTED TEMPERATURE CONDITIONS, PASSING AN ELECTRIC CURRENT THROUGH THE THERMOELECTRIC ASSEMBLY IN A PREDETERMINED DIRECTION TO EFFECT THE TRANSFER OF HEAT BETWEEN THE BODIES UNTIL SAID PREDETERMINED TEMPERATURE CONDITIONS OF THE BODIES ARE RESTORED WITH THE ELECTRIC CURRENT BEING THAT AT WHICH THE MAXIMUM QUANTITY OF HEAT IS TRANSFERRED BY THE THERMOELECTRIC ASSEMBLY SUBSEQUENTLY PASSING THROUGH THE THERMOELECTRIC ASSEMBLY IN A PREDETERMINED DIRECTION AN ELECTRIC CURRENT AT WHICH THE ASSEMBLY OPERATES MOST EFFICIENTLY, AND STOPPING THE PASSAGE OF ELECTRIC CURRENT THROUGH THE THERMOELECTRI ASSEMBLY WHEN THE PREDETERMINED TEMPERATURE CONDITIONS ARE EXCEEDED BEYOND PREDETERMINED LIMITS.
