Abstract

1335785 Thermal relays; demagnetizing cathode-ray tube apparatus STANDARD TELEPHONES & CABLES Ltd 25 July 1972 34637/72 Headings H3B and H4T [Also in Division H1] A CRT is demagnetized or an electric motor is started by a circuit comprising three thermistors in good thermal contact with one another, one thermistor A having a negative temperature coefficient and the other two thermistors B, C having positive temperature coefficients. When energized a heavy current initially flows through the load but as the thermistors heat up this is gradually reduced to a very low level.
