Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A METHOD OF REGULATING THE HEATING VALVE OF A FUEL GAS A HIGH HEATING VALUE WHICH COMPRISES BURNING A PORTION OF A FUEL GAS IN AN INTERNAL COMBUSTION ENGINE IN THE PRESENCE OF INSUFFICIENT OXYGEN TO FULLY BURN THE FUEL GAS TO GENERATE POWER AND PRODUCE AN EXHAUST GAS OF LOW HEATING VALUE, MIXING THE EXHAUST GAS WITH SAID FUEL GAS TO PRODUCE A MIXED GAS HAVING A HEATING VALUE INTERMEDIATE THE HEATING VALUES OF SAID FUEL GAS AND SAID EXHAUST GAS, CONTINUOUSLY DETERMINING THE HEATING VALUE OF THE MIXED GAS AND REGULATING THE SPEED OF SAID ENGINE TO PRODUCE EXHAUST GAS AT AN INCREASED RATE WHEN THE HEATING VALUE OF THE MIXED GAS EXCEEDS A PREDETERMINED VALUE AND AT A DECREASED RATE WHEN THE HEATING VALUE OF THE GAS IS LESS THAN SAID PREDETERMINED VALUE.
Claim 2
Independent Claim

Claim 3
Independent Claim
223 words
A SYSTEM FOR REGULATING THE HEATING VALUE OF A FUEL GAS TO MAINTAIN ITS HEATING VALUE SUBSTANTIALLY CONSTANT, COMPRISING CONDUIT MEANS FOR A FLOWING STREAM OF FUEL GAS UNDER PRESSURE, AN ENGINE OPERABLE ON SAID FUEL GAS, MEANS FOR SUPPLYING FUEL GAS FROM SAID CONDUIT TO SAID ENGINE, MEANS FOR SUPPLYING AN OXYGEN-CONTAINING GAS UNDER PRESSURE TO SAID ENGINE AT A RATE SUFFICIENT TO SUPPORT COMBUSTION OF THE FUEL GAS IN THE ENGINE BUT INSUFFICIENT TO BURN THE FUEL GAS COMPLETELY, WHEREBY SAID ENGINE PRODUCES POWER AND EXHAUST GAS OF LOW HEATING VALUE, MEANS FOR CONDUCTING SAID EXHAUST GAS FROM SAID ENGINE TO THE CONDUIT MEANS TO MIX WITH THE FUEL GAS THEREIN, MEANS COMMUNICATING WITH SAID CONDUIT DOWNSTREAM OF SAID ENGINE FOR DETERMINING THE HEATING VALUE OF THE MIXED GAS IN SAID CONDUIT MEANS, AND MEANS RESPONSIVE T O THE MEANS FOR DETERMINING THE HEATING VALUE OF THE GAS AND TO VARIATION OF THE HEATING VALUE OF THE MIXED GASES FROM A PREDETERMINED VALUE FOR INCREASING THE SPEED OF THE ENGINE TO INCREASE THE RATE OF PRODUCTION OF THE EXHAUST GAS WHEN THE HEATING VALUE AND DECREASING THE EXCEEDS SAID PREDETERMINED VALUE AND DECREASING THE SPEEDS OF SAID ENGINE TO DECREASE THE RATE OF PRODUCTION OF THE EXHAUST GAS WHEN THE HEATING VALUE OF THE GAS IS LESS THAN SAID PREDETERMINED VALUE.
