A METHOD FOR THE CONTINUOUS REGULATION OF THE DISTANCE BETWEEN THE ANODE AND MERCURY CATHODE OF ELECTROLYTIC MERCURY CELLS USED IN THE ELECTROLYSIS OF BRINE, EACH OF SAID MERCURY CELLS HAVING SWITCHING MEANS AND CIRCUIT MEANS CONNECTING THE CATHODE OF EACH MERCURY CELL WITH THE ANODE OF THE NEXT MERCURY CELL, THE STEPS COMPRISING: (A) DISCONNECTING SAID SWITCHING MEANS TO DISCONTINUE THE ELECTROLYSIS; (B) CONNECTING MEASURING INSTRUMENT MEANS IN SERIES WITH THE ANODE TO BE REGULATED AND THE MERCURY CATHODE WITH WHICH SAID ANODE COOPERATES TO PRODUCE AN ELECTROLYSIS; (C) ADVANCING SAID ANODE TO BE REGULATED TOWARD SAID MERCURY CATHODE; (D) HALTING THE ADVANCE OF SAID ANODE WHEN SAID MEASURING INSTRUMENT MEANS ADAPTED TO INDICATE VOLTAGE AND CURRENT INDICATES A SUDDEN DECREASE; AND (E) RETRACTING SAID ANODE FROM A POINT IN SPACE AT WHICH IS TWAS HALTED A PREDETERMINED DISTANCE SAID DISTANCE BEING CHOSEN FOR PRODUCUNG OPTIMUM CONDITIONS FOR MAXIMUM ELECTROLYSIS PRODUCTION.
