Abstract
612,742. Electric heating resistances. PHILIPS LAMPS, Ltd. May 31, 1946, No. 16549. Convention date, Feb. 20, 1942. [Class 39 (iii)] [Also in Group XXXVI] A layer of lustrous carbon is deposited on refractory insulating tubular bodies 6, more particularly in the manufacture of electrical resistances, by passing the tubular bodies 6 in succession through a cool-walled chamber 1 filled with a neutral gas and into which a cool gaseous carbon compound is introduced, the said bodies being simultaneously heated from within to the temperature necessary for the separation and deposition of carbon thereupon. The tubular bodies 6 slide on an electrically conducting rod 9, which has a contracted part 10 for ' localized heating and extends through the chamber 1 from an inlet pipe 4 to an outlet pipe 5. The pipes 4 and 5 are furnished with lateral branches 7 and 8 through which the neutral gas, e.g. nitrogen, is introduced into the chamber 1. A carbon layer having a resistance of approximately 2,400 ohms is stated to be deposited on a tubular body having an external diameter of 4 mms. and a length of 25 mms. by passing the body through nitrogen containing ¢ per cent of C2H2 and heating the body to a temperature of 1100‹ C. for one minute.
