Abstract

788,177. Temperature-sensitive resistors. SOC. LE CARBONE LORRAINE, and MILLET, J. March 10, 1955 [March 18, 1954], No. 7058/55. Class 37. [Also in Group XXXVII] A switch contact comprises mixture of silver and a thermistor material consisting of 45 per cent each of cobalt and manganese oxides and 10 per cent of nickel oxide, the silver forming from 65 to 90 per cent of the whole.
