Abstract
682,887. Electric resistances. BRITISH THOMSON-HOUSTON CO., Ltd. July 10, 1950 [July 22, 1949], No. 17214/50. Class 37. An electric resistance comprises a mixture of metal sulphides including molybdenum sulphide and at least one sulphide of a metal in Group II of the Periodic Table. The materials are finely grounded, pressed and preferably sintered. The resistance has a negative temperature coefficient. Free sulphur may be added. The leads may be of platinum, molybdenum, chromium, nickel and in use they combine with the sulphur to form a thin film of sulphide; to prevent asymmetry of resistance developing, the resistance is subjected to a heavy direct current, first in one direction and then in the other to form stable sulphide films on both electrodes. Preferably the molybdenum sulphide forms 0.03 to 10 per cent by weight of the composition and cadmium, calcium or zinc sulphide forms 3 to 98 per cent. A powdered metal may be added. The resistance may be enclosed in a glass envelope or may be constituted by a cylindrical metal cup 14 containing the mixture 15 into which extends a lead 16.
