Claim 1
Independent Claim
193 words
THE METHOD OF EXPANDING AN EXPANSIBLE CHAMBER UNDER PRESSURE COMPRISING ALTERNATELY INJECTING LIQUEFIED GAS IN ITS VAPOR PHASE AND ITS LIQUID PHASE AT A CONSTANT VOLUME OF FLOW THEREOF INTO A CONFINED SPACE ADJACENT TO SAID CHAMBER AND IN COMMUNICATION THEREWITH, REDUCING THE PRESSURE IN THE CHAMBER BY ASPIRATING FLUID FROM SAID CHAMBER BY THE FLOW OF VAPOR PHASE GAS INJECTED INTO SAID CONFINED SPACE, HALTING SAID ASPIRATION AND SAID REDUCTION OF PRESSURE BY THE INJECTION OF LIQUID PHASE GAS INTO SAID CONFINED SPACE FOR THE ABSORPTION OF LATENT HEAT OF VAPORIZATION FROM THE WALLS OF SAID SPACE TO VAPORIZE SAID INJECTED LIQUID PHASE GAS IN SAID SPACE TO INCREASE THE RESULTANT AMOUNT OF VAPOR AND THE PRESSURE EXERTIBLE THEREBY IN SAID CHAMBER ABOVE THAT INDUCED BY SAID INJECTION OF VAPOR PHASE GAS ALONE, AND VENTING VAPOR FROM SAID SPACE AT SUBSTANTIALLY CONSTANT VOLUME OF FLOW EQUAL TO THE VOLUME OF FLOW OF VAPOR INJECTED INTO SAID SPACE TO ACCUMULATE IN SAID SPACE AND CHAMBER FOR BRIEF PERIODS OF TIME PORTIONS OF SAID INCREASED AMOUNTS OF VAPOR DURING LIQUID PHASE INJECTION TO DEVELOP A PRESSURE INCREASE IN SAID SPACE FOR EXPANDING SAID CHAMBER.
