Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
97 words
A GAS BURNER AND IGNITION SYSTEM, COMPRISING: A GAS BURNER TO BE IGNITED; A GAS CONTROL FOR SAID BURNER; A PIEZOELECTRIC ELEMENT RESPONSIVE TO CHANGES IN COMPRESSIVE FORCES THEREON TO GENERATE VOLTAGES FOR IGNITING SAID BURNER; IGNITER MEANS RESPONSIVE TO VOLTAGES GENERATED BY SAID PIEZOELECTRIC ELEMENT TO IGNITE GAS FROM SAID BURNER; MEANS RESPONSIVE TO HEAT GENERATED BY SAID BURNER DURING A GIVEN PERIOD OF ITS BURNING TO PRODUCE STORED MECHANICAL ENERGY; AND MEANS RESPONSIVE TO A LATER OPERATION OF SAID GAS CONTROL FOR RELEASING SAID STORED ENERGY TO CHANGE SAID COMPRESSIVE FORCES ON SAID PIEZOELECTRIC ELEMENT.
