Claim 1
Independent Claim
145 words
THE COMBINATION OF MEANS FOR MAINTAINING AT A CONSTANT TEMPERATURE A COMPOUND WHICH GENERATES A GAS PRESSURE UPON ITS THERMAL DECOMPOSITION, A GASUGE INCLUDING AN ELEMENT MOVABLE UPON A DIFFERENCE IN PRESSURES APPLIED TO ITS OPPOSED SURFACES, A MIRROR MOVABLE WITH SAID ELEMENT, MEANS FOR APPLYING SAID GENERATED GAS PRESSURE TO ONE OF SAID SURFACES, MEANS FOR DIRECTING A LIGHT BEAM TO SAID MIRROR, A SCALE, A PAIR OF PHOTOELECTRIC CELLS SUPPORTED BY AND MOVABLE ALONG SAID SCALE SAID PHOTOELECTRIC CELLS BEING SPACED APART AND SO LOCATED THAT THE LIGHT BEAM REFLECTED FROM SAID MIRROR STRIKES ONE OF SAID CELL WHEN THE PRESSURE AT THE OPPOSED SURFACES OF SAID ELEMENT ARE EQUAL AND MOVES TOWARD THE OTHER OF SAID CELLS AS THE DIFFERENCE BETWEEN SAID PRESSURE INCREASES, A SOURCE OF GAS PRESSURE, AND VALUE MEANS ACTUATED WHEN SAID REFLECTED BEAM REACHES SAID OTHER CELL TO
