Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
138 words
AN ELECTRICAL TRANSFORMER COMPRISING, A TANK HAVING A LIQUID ELECTRICAL INSULATING DIELECTRIC DISPOSED THEREIN, A PLURALITY OF ELECTRICAL WINDINGS DISPOSED IN INDUCTIVE RELATION WITH A MAGNETIC CORE AND POSITIONED WITHIN SAID TANK, A PLURALITY OF THERMOELECTRIC COOLING DEVICES EACH HAVING A COLD PORTION AND A HOT PORTION WHEN AN ELECTRIC CURRENT FLOWS THERETHROUGH, SAID PLURALITY OF THERMEOELECTRIC DEVICES BEING ASSOCIATED WITH SAID TANK, WITH THEIR COLD PORTIONS BEING IN HEAT INDUCTIVE RELATION WITH SAID INSULATING DIELECTRIC AND THEIR HOT PORTIONS BEING DISPOSED TO RADIATE HEAT TO THE AIR SURROUNDING SAID TANK, A RECTIFIER DISPOSED WITHIN SAID TANK, AND MEANS CONNECTING SAID PLURALITY OF THERMOELECTRIC DEVICES, ONE OF SAID PLURALITY OF ELECTRICAL WINDINGS, AND SAID RECTIFIER IN ELECTRIC CIRCUIT RELATION SUCH THAT ELECTRIC CURRENT WILL FLOW THROUGH SAID THERMOELECTRIC DEVICES WHEN SAID TRANSFORMER IS ENERGIZED WITH AN ELECTRIC POTENTIAL.
