110 words
THE METHOD OF DETERMINING INCIPIENT AND OPTIMUM REACTION TEMPERATURE OF TEST MATERIALS IN CONTACT WITH A CHEMICALLY REACTIVE GAS, WHICH COMPRISES PROGRESSIVELY CHANGING THE TEMPERATURE OF SAID MATERIALS IN ACCORDANCE WITH A KNOWN FUNCTION OF TIME WHILE CONTINUOUSLY PASSING A MIXTURE OF KNOWN CONSTANT CONSTITUENCY OF SAID REACTIVE GAS AND AN INERT CARRIER GAS OF DIFFERENT THERMAL CONDUCTIVITY FROM SAID REACTIVE GAS THROUGH A REFERENCE GAS THERMAL CONDUCTIVITY DETECTOR, THEN INTO CONTACT WITH SAID TEST MATERIAL, AND FINALLY THROUGH AN EFFLUENT GAS THERMAL CONDUCTIVITY DETECTOR, AND SENSING AND RECORDING THE TEMPERATURE POINTS AT WHICH SIGNIFICANT CHANGES IN CONCENTRATION OF SAID EFFLUENT REACTIVE GAS RELATIVE TO SAID INERT CARRIER GAS OCCUR.
