Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
107 words
THE METHOD OF VAPORIZING A CYOGENIC LIQUID SELECTED FROM THE CLASS CONSISTING OF LIQUID OXYGEN, LIQUID NITROGEN, LIQUEFIED NATURAL GAS AND LIQUID METHANE, FOR UTILIZATION IN A GAS DISTRIBUTION SYSTEM WHICH COMPRISES PASSING THE CRYOGENIC LIQUID THROUGH A CONFINED PATH, HEATING SAID PATH BY PASSING WATER THEREOVER TO FORM A RELATIVELY THICK ICE CAKE ON SAID PATH, AND THEREAFTER SUBSTANTIALLY CONTINUOUSLY ADDING FURTHER HEAT AT A CONTROLLED RATE TO SAID CRYOGENIC LIQUID BY PASSING WATER OVER THE ICE CAKE WITHOUT SUBSTANTIAL FORMATION OF FURTHER ICE, SAID ICE CAKE BEING PROPORTIONED IN THICKNESS TO THE HEAT ABSORPTION RATE AND TEMPERATURE DIFFERENTIAL BETWEEN THE CRYOGENIC LIQUID AND WATER STREAM.
