Claim 1
Independent Claim
144 words
IN A PROCESS WHEREIN THE TEMPERATURE OF A FLUID MASS IS AFFECTED BY THE TEMPERATURE OF CONTINUOUSLY ADDED DILUENT AND THE TEMPERATURE OF A HEAT EXCHANGE MEDIUM IN INDIRECT HEAT EXCHANGE THEREWITH, THE IMPROVED METHOD OF CONTROLLING THE TRMPERATURE OF SAID FLUID MASS WHICH COMPRISES SENSING THE TEMPERATURES OF SAID FLUID MASS AND SAID DILUENT, INCREASING THE TEMPERATURE OF SAID DILUENT IN RESPONSE TO A DECREASE IN THE TEMPERATURE OF SAID FLUID MASS AND DECREASING THE TEMPERATURE OF SAID DILUENT IN RESPONSE TO AN INCREASE IN TEMPERATURE OF SAID FLUID MASS, PRODUCING A POTENTIAL PROPORTIONAL TO THE SUM OF A GIVEN DESIRED TEMPERATURE FOR SAID FLUID MASS MINUS SAID TEMPERATURE OF SAID FLUID MASS PLUS SAID TEMPERATURE OF SAID DILUENT MINUS A GIVEN DESIRED TEMPERTURE FOR SAID DILUENT, AND CHANGING THE TEMPERATURE OF SAID HEAT EXCHANGE MEDIUM IN RESPONSE AND PROPORTIONAL TO SAID POTENTIAL.
