Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
91 words
APPARATUS FOR VAPORIZING LIQUID CARBON DIOXIDE COMPRISING, A HEAT EXCHANGER IN COMMUNICATION WITH A LIQUID CARBON DIOXIDE SUPPLY SOURCE, A COIL ADAPTED TO RECEIVE LIQUID CARBON DIOXIDE FROM SAID HEAT EXCHANGER, AUTOMATICALLY CONTROLLED MEANS FOR SUPPLYING HEAT TO SAID COIL TO VAPORIZE SAID LIQUID CARBON DIOXIDE, MEANS FOR PASSING THE VAPORIZED CARBON DIOXIDE FROM SAID COIL THROUGH SAID HEAT EXCHANGER, AND AUTOMATIC VALVE MEANS RESPONSIVE TO CHANGES IN THE TEMPERATURE OF THE CARBON DIOXIDE VAPOR PASSING FROM SAID COIL FOR CONTROLLING THE PASSAGE OF CARBON DIOXIDE VAPOR FROM SAID HEAT EXCHANGER.
Claim 2
Dependent Claim
91 words
APPARATUS FOR VAPORIZING LIQUID CARBON DIOXIDE COMPRISING, A HEAT EXCHANGER IN COMMUNICATION WITH A LIQUID CARBON DIOXIDE SUPPLY SOURCE, A COIL ADAPTED TO RECEIVE LIQUID CARBON DIOXIDE FROM SAID HEAT EXCHANGER, AUTOMATICALLY CONTROLLED MEANS FOR SUPPLYING HEAT TO SAID COIL TO VAPORIZE SAID LIQUID CARBON DIOXIDE, MEANS FOR PASSING THE VAPORIZED CARBON DIOXIDE FROM SAID COIL THROUGH SAID HEAT EXCHANGER, AND AUTOMATIC VALVE MEANS RESPONSIVE TO CHANGES IN THE TEMPERATURE OF THE CARBON DIOXIDE VAPOR PASSING FROM SAID COIL FOR CONTROLLING THE PASSAGE OF CARBON DIOXIDE VAPOR FROM SAID HEAT EXCHANGER.
Claim 3
Dependent Claim
127 words
APPARATUS FOR VAPORIZING LIQUID CARBON DIOXIDE COMPRISING, A HEAT EXCHANGER ADAPTED TO RECEIVE LIQUID CARBON DIOXIDE FROM A SUPPLY SOURCE, HEATING MEANS IN COMMUNICATION WITH SAID HEAT EXCHANGER FOR RECEIVING LIQUID CARBON DIOXIDE FROM THE HEAT EXCHANGER, MEANS FOR SUPPLYING HEAT TO SAID HEATING MEANS, AUTOMATIC MEANS RESPONSIVE TO THE TEMPERATURE OF THE CARBON DIOXIDE AT THE DISCHARGE OF THE HEATING MEANS FOR CONTROLLING THE AMOUNT OF HEAT SUPPLIED TO SAID HEATING MEANS TO COMPLETELY VAPORIZE THE LIQUID CARBON DIOXIDE AND ELEVATE THE TEMPERATURE OF THE RESULTANT VAPOR TO A POINT ABOVE ITS VAPORIZING TEMPERATURE, AND MEANS FOR PASSING THE HEATED CARBON DIOXIDE VAPOR FROM SAID HEATING MEANS THROUGH SAID HEAT EXCHANGER TO LOWER THE TEMPERATURE OF SAID VAPOR AND PARTIALLY VAPORIZE THE ASSOCIATED LIQUID CARBON DIOXIDE.
