Temperature measuring systems

Claim 1

AN ELECTRICAL ARRANGEMENT FOR PROVIDING A CONTINUOUS MEASUREMENT INDICATION REPRESENTING THE CONTINOUSLY VARIABLE SOLUTION VALUE S OF AN EQUATION OF THE GENERAL FORM S=X$N(Y) WHERE X AND Y ARE VARIABLE TEMPERATURE VALUES AND N IS A CONSTANT, SAID ARRANGEMENT COMPRISING A FIRST THERMOCOUPLE DEVICE FOR SUBJECTION TO TEMPERATURE X AT A FIRST PHYSICAL POSITION, SAID FIRST THERMOCOUPLE DEVICE HAVING A FIRST THERMOJUNCTION BETWEEN AN ELEMENT OF A FIRST MATERIAL AND AN ELEMENT OF A SECOND MATERIAL, A SECOND THERMOCOUPLE DEVICE FOR SUBJECTION TO TEMPERATURE Y AT A SECOND PHYSCIAL POSITION DIFFERENT FROM SAID FIRST PHYSICAL POSITION, SAID SECOND THERMOCOUPLE DEVICE HAVING A SECOND THERMOJUNCTION BETWEEN AN ELEMENT OF SAID FIRST MATERIAL AND AN ELEMENT OF A THIRD MATERIAL AND A THIRD THERMOJUNCTION BETWEEN AN ELEMENT OF SAID SECOND MATERIAL AND AN ELEMENT OF A FOURTH MATERIAL, A FIRST CONNECTING LEAD BETWEEN SAID FIRST MATERIAL ELEMENT OF SAID FIRST THERMOJUNCTION AND SAID FIRST MATERIAL ELEMENT OF SAID SECOND THERMOJUNCTION, SAID CONNECTING LEAD BEING WHOLLY OF SAID FIRST MATERIAL, A SECOND CONNECTING LEAD BETWEEN SAID SECOND MATERIAL ELEMENT OF SAID FIRST THERMOJUNCTION AND SAID SECOND MATERIAL ELEMENT OF SAID THIRD THERMOJUNCTION, SAID SECOND CONNECTING LEAD BEING WHOLLY OF SAID SECOND MATERIAL, AN ELECTRIC CURRENT OPERATED DEVICE HAVING FIRST AND SECOND INPUT TERMINALS, A THIRD CONNECTING LEAD BETWEEN SAID THIRD MATERIAL ELEMENT OF SAID SECOND THERMOJUNCTION AND SAID FIRST INPUT TERMINAL OF SAID CURRENT OPERATED DEVICE, SAID THIRD CONNECTING LEAD BEING WHOLLY OF SAID THIRD MATERIAL AND A FOURTH CONNECTING LEAD BETWEEN SAID FOURTH MATERIAL ELEMENT OF SAID THIRD THERMOCOUPLED DEVICE AND SAID SECOND INPUT THERMINAL OF SAID CURRENT OPERATED DEVICE, SAID FOURTH CONNECTING LEAD BEING WHOLLY OF SAID FOURTH MATERIAL, SAID FIRST, SECOND, THIRD AND FOURTH MATERIAL BEING SO CHOSEN THAT THE THERMOELECTRIC POWER OF SAID FIRST AND THIRD MATERIALS IS P TIMES THE THERMOELECTRIC POWER OF SAID FIRST AND SECOND MATERIALS AND THE THERMOELECTRIC POWER OF SAID FOURTH AND SECOND MATERIALS IS Q TIMES THE THERMOELECTRIC POWER OF SAID FIRST AND SECOND MATERIALS WHERE THE SUM OF SAID FACTORS P AND Q IS EQUAL TO SAID FACTOR N.
