Claim 1

APPARATUS FOR AUTOMATIC IGNITION OF EXCESS GAS IN A FLASRE PIPE FOR A MAIN GAS PIPE FEEDING GAS FROM A GAS PRODUCER TO A COKE OVEN BATTERY TO UNDERFIRE THE SAME, COMPRISING: A MAIN GAS PIPE FOR OFF-FLOW OF GAS FROM A GAS PRODUCER TO A COKE OVEN; A FLARE PIPE AND OPEN WARDLY TO A HIGH LEVEL ABOVE THE MAIN GAS PIPE AND OPEN TO THE ATMOSPHERE AT ITS UPPER PART FOR DISCHARGE OF EXCESS GAS FROM THE MAIN GAS PIPE INTO THE ATMOSPHERE; TWO IMMERSION BELLS FIXEDLY CONNECTED TOGETHER FOR MOVEMENT IN UNISON, WITH ONE BELL OPERATIVELY ASSOCIATED WITH SAID MAIN GAS PIPE AND BEING OPERABLE BY THE GAS PRESSURE IN THE MAIN GAS PIPE TO RAISE AND LOWER THE TWO BELLS IN UNISON IN RESPONSE TO CHANGES IN PRESSURE OF THE GAS IN THE MAIN GAS PIPE, AND THE OTHER BELL OPERATIVELY ASSOCIATED WITH SAID MAIN GAS PIPE AND OPENING AND CLOSING A COMMUNICATION BETWEEN THE LOWER PART OF THE FLARE PIPE AND THE MAIN GAS PIPE IN CORRESPONDENCE WITH THE MOVEMENT OF THE FIRST BELL IN RESPONSE TO CHANGES OF GAS PRESSURE IN THE MAIN GAS PIPE; AN ELECTRICAL RESISTANCE IGNITION DEVICE AT THE UPPER PART OF THE FLARE PIPE WHERE IT IS OPEN FOR DISCHARGE OF EXCESS GAS TO THE ATMOSPHERE; ELECTRICAL CIRCUIT MEANS INCLUDING SWITCHING MEANS FOR IMPAIRING HEAT TO SAID IGNITION DEVICE FOR EFFECTION IGNITION THEREBY; AND MECHANICAL ACTUATING MEANS OPERATIVELY ASSOCIATED WITH THE SWITCHING MEANS AND WITH THE TWO BELLS FOR OPERATION THEREBY FOR CLOSING THE SWITCHING MEANS AND ENERGIZING THE CIRCUIT MEANS IN RESPONSE TO A PREDETERMINED GAS PRESSURE IN SAID MAIN GAS PIPE, TO SET THE ELECTRICAL CIRCUIT MEANS INTO OPERATION TO IGNITE THE FLARE PIPE DURING PASSAGE OF GAS THERETHROUGH FROM THE MAIN GAS PIPE BY WAY OF SAID OTHER BELL; CHARACTERIZED BY SAID FLARE PIPE BEING FREE OF OBSTRUCTION TO GAS FLOW FROM THE UPPER PART OF THE FLARE PIPE, WHERE IT IS OPEN TO DISCHARGE TO THE ATMOSPHERE, DOWN TO THE REGION AT WHICH THE OTHER BELL OPENS AND CLOSES THE AFORESAID COMMUNICATION BETWEEN THE FLARE PIPE AND THE MAIN GAS PIPE, AND BY SAID CIRCUIT MEANS INCLUDING A TIME DELAY MEANS FOR DELAYING THE TIME THAT THE CIRCUIT MEANS IS SET INTO OPERATION AFTER THE INITIAL ACTUATING OF THE ACTUATING MEANS, FOR DELAYING THE OPERATION OF TH IGNITION DEVICE UNTIL A TIME AFTER THE ENTRY OF THE GAS INTO THE FLARE PIPE, FOR SCAVENGING THE SAME TO PREVENT EXPLOSIONS THEREIN, AND SAID CIRCUIT MEANS ALSO INCLUDING A SEPARATE ELECTRICAL CIRCUIT INCLUDING ELECTRICAL TIME DELAY MEANS FOR AUTOMATICALLY INTERRUPTING THE OPERATION OF THE CIRCUIT MEANS AFTER IT HAS IMPARTED IGNITING HEAT TO THE IGNITION DEVICE FOR INTERRUPTION OF THE IGNITION, AFTER THE IGNITION OF THE FLARE PIPE HAS TAKEN PLACE.
