Claim 1
Independent Claim
215 words
A DEVICE FOR THERMOGRAPHIC CALORIMETRY COMPRISING: MEANS FOR CONTINUOUSLY HEATING AND COOLING THE SAMPLE UNDER INVESTIGATION AT A PREDETERMINED RATE; A BLOCK FOR MEASURING THE TEMPERATURE AND SENSING CHANGES IN THE HEAT CONTENT OF SAID SAMPLE, SAID BLOCK BEING PROVIDED WITH A HEAT INSULATING CASING AND DIVIDED BY A HEAT INSULATING PARTITION INTO TWO IDENTICAL CHAMBERS, ONE OF WHICH CONTAINS THE SAMPLE UNDER STUDY AND THE OTHER A STANDARD SOURCE OF HEAT RADIATION, EACH CHAMBER INCLUDING LOWOHMIC RESISTORS ARRANGED IN SPACED RELATION AROUND SAID SAMPLE UNDER INVESTIGATION AND SAID STANDARD SOURCE OF HEAT RADIATION; ALL OF SAID ELEMENTS IN EACH OF SAID CHAMBERS AND SAID MEANS FOR CONTINUOUSLY HEATING AND COOLING SAID SAMPLE UNDER INVESTIGATION AT A PREDETERMINED RATE BEING ARRANGED IN ACCORDANCE WITH THEIR THERMAL AND PHYSICAL PROPERTIES IN SYMMETRIC RELATION ABOUT THE VERTICAL AXIS OF SAID DEVICE, ALL SAID ELEMENTS, SAVE SAID SAMPLE, BEING BALANCED IN ACCORDANCE WITH THEIR THERMAL AND PHYSICAL PROPERTIES SO THAT EACH CHAMBER IS SUPPLIED WITH AN IDENTICAL QUANTITY OF HEAT PER UNIT TIME, MEANS FOR RECORDING TEMPERATURE AND QUANTITY OF HEAT OVER TIME IN DIRECT AND DIFFERENTIAL FORM, THE LATTER SAID MEANS BEING CONNETED WITH SAID LOW-OHMIC RESISTORS, AND MEANS CONNECTED WITH SAID STANDARD SOURCE OF HEAT RADIATION FOR POWERING THE SAME AND MEASURING THE POWER REQUIRED THEREBY.
