Abstract
1381337 Measuring temperature electrically to monitor chemical reaction McNEIL CORP 20 April 1972 [26 April 1971] 50012/73 Divided out of 1381336 Heading G1N Apparatus monitoring vulcanizing processes in tire moulds M includes means for inserting an electrically responsive temperature sensing element e.g. a thermistor into each of the moulds and into contact with the tire material a constant voltage being maintained across the element whereby the current passed by the element is indicative of the rate of curing of the tire. Each thermistor is inserted into a mould by an air cylinder C, which preferably embeds the thermistor in the tire material. Each thermistor is fed with a constant direct voltage of +1 volt and provides a current representative of material temperature to respective amplifiers 131, 132 from which signals are passed to log amplifiers 133, 134 and after scaling in amplifiers 137, 138 to antilog amplifiers 139, 140. Comparator 106 acts with logic circuits to select the signal representative of the lower temperature which is passed to output lead 112 and whereby, it is stated, it is assured that a tire in a twin mould press will not be undercured.
