Abstract
In using a gas torch it is often necessary to maintain a uniform flame. This can be accomplished by maintaining a constant pressure at the torch tip. A pressure transducer is placed at the output of a generator that produces gas by electrolysis for the torch. The transducer indicates changes in the gas pressure by changing resistance. The transducer is coupled to a resistance-capacitance circuit and forms a variable part of the resistance of the circuit. This circuit, in turn, is coupled to the firing gate of a triac which controls the rate of gas disassociation of the electrolytic solution in the gas generator by varying the amount of current fed to the gas generator. When the pressure at the output of the generator varies, the resistance of the pressure transducer changes thereby changing the RC time constant of the resistance-capacitance circuit. Such a change modifies the firing rate of the triac and, therefore, the rate of gas generation and pressure.
