Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
180 words
A PRESSURE-OPERATED ELECTROLYZER APPARATUS COMPRISING A PLURALITY OF PRESSURE-RESISTING CELLS, EACH CELL BEING SEPARATED BY A DIAPHRAGM INTO AN ANODE CHAMBER AND A CATHODE CHAMBER; RECEPTACLE MEANS DEFINING TWO GAS CHAMBERS ADAPTED TO BE PARTIALLY FILLED WITH A LIQUID, A TUBE SYSTEM INTERCONNECTING THE LOWER PORTIONS OF SAID CHAMBERS, A FIRST GAS DELIVERY TUBE SYSTEM FOR DELIVERING GAS FROM SAID ANODE CHAMBERS TO ONE OF SAID GAS CHAMBERS, AND A SECOND GAS DELIVERY TUBE SYSTEM FOR DELIVERING GAS FROM SAID CATHODE CHAMBERS TO THE OTHER OF SAID GAS CHAMBERS; A ONE WAY GAS OUTLET VALVE CONNECTED TO ONE OF SAID GAS CHAMBERS ABOVE SAID INTERCONNECTING TUBE SYSTEM BIASED TO RELEASE GAS THEREFROM AT PRESSURES EXCEEDING A PREDETERMINED VALVE, AND AN INDEPENDENT SECOND GAS OUTLET VALVE CONNECTED TO THE OTHER OF SAID GAS CHAMBERS ABOVE SAID INTERCONNECTING TUBE SYSTEM; AND LIQUID LEVEL ACTUATED MEANS FOR CLOSING SAID SECOND VALVE WHEN THE LIQUID LEVEL WITHIN ITS ASSOCIATED GAS CHAMBER EXCEEDS A PREDETERMINED VALUE AND OPENING SAID SECOND VALVE WHEN THE LIQUID LEVEL WITHIN ITS ASSOCIATED GAS CHAMBER FALLS BELOW A PREDETERMINED VALUE.
