Abstract

990,023. Electric heating resistances. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 29, 1962 [March 13, 1961], No. 9087/61. Heading H5H. [Also in Division HI] An electric heating resistance element comprises a path of resistive material, e.g. 80/20 nickel-chromium, deposited as by flame-spraying on a heat-resistant insulating, e.g. ceramic, layer formed on a metal base plate. Insulating layers and resistance elements may be formed on both sides of the plate, the elements being separate or connected in series or parallel.
