Compressed gas circuit breaker with closed gas circuit

Claim 1

IN AN ELECTRICAL CIRCUIT BREAKER SYSTEM OPERATING ON A CLOSED GAS CIRCUIT THE COMBINATION COMPRISING A CIRCUIT BREAKER HAVING SEPARATE HIGH PRESSURE AND LOW PRESSURE GAS CHAMBERS BETWEEN WHICH THE GAS FLOWS WHEN THE CIRCUIT BREAKER CONTACTS ARE OPENED, A DOUBLE GAS RESERVOIR HAVING A HIGH PRESSURE AND LOW PRESSURE GAS CHAMBERS, A COMPRESSOR CONNECTED BETWEEN SAID HIGH AND LOW PRESSURE CHAMBERS OF SAID DOUBLE RESERVOIR, PIPE LINES CONNECTING SAID HIGH AND LOW PRESSURE CAMBERS OF SAID RESERVOIR WITH SAID HIGH AND LOW PRESSURE CHAMBERS OF SAID CIRCUIT BREAKER, TRANSFER VALVE MEANS IN SAID PIPE LINES FOR CONTROLLING GAS FLOW BETWEEN SAID RESERVOIR CHAMBERS AND SAID CIRCUIT BREAKER CHAMBERS, PIPE LINE MEANS DIRECTLY INTERCONNECTING SAID HIGH AND LOW PRESSURE CHAMBERS OF SAID CIRCUIT BREAKER, SWITCH CHAMBER INTERCONNECTING VALVE MEANS INTERPOSED IN AND CONTROLLING GAS FLOW THROUGH SAID PIPE LINE MEANS WHICH DIRECTLY INTERCONNECTED SAID HIGH AND LOW PRESSURE CHAMBERS OF SAID CIRCUIT BREAKER, A PRESSURE DIFFERENCE IN GAS PRESSURE IN SAID HIGH VARIABLE WITH THE DIFFERENCE IN GAS PRESSURE IN SAID HIGH AND LOW PRESSURE CHAMBERS OF SAID CIRCUIT BREAKER, AND MEANS RESPONSIVE TO THE OUTPUT FROM SAID PRESSURE DIFFERENCE RESPONSIVE FOR CONTROLLING OPERATION OF SAID TRANSFER VALVE MEANS AND SAID SWITCH CHAMBER INTERCONNECTING VALVE MEANS SUCH THAT WHEN SAID PRESSURE DIFFERENCE DECREASES, SAID TRANSFER VALVE MEANS OPEN TEMPORARILY TO ESTABLISH GAS FLOW FROM SAID DOUBLE RESERVOIR THROUGH SAID PIPE LINES TO SAID HIGH AND LOW PRESSURE CHAMBERS OF SAID CIRCUIT BREAKER, AND WHEN SAID PRESSURE DIFFERENCE INCREASES, SAID SWITCH CHAMBER INTERCONNECTING VALVE MEANS IS OPENED TEMPORARILY TO ESTABLISH DIRECT COMMUNICATION BETWEEN SAID HIGH AND LOW PRESSURE CHAMBERS OF SAID CIRCUIT BREAKER.
