Abstract

617,834. Insulators. BULLERS, Ltd., and PERRINS, G. Oct. 11, 1946, No. 30365. Drawings to Specification. [Class 36] An electric insulator has two conductive coatings provided on the surface, one having a positive temperature coefficient of resistance and the other a negative temperature coefficient of resistance, the coatings being so arranged as to provide between them a resistance, the value of which is independent of temperature changes. The coatings may be in the form of conductive bands extending over the surface of the insulator between the metal electrodes, as described in Specification 617,833. Specification 527,357 also is referred to.
