Abstract

683,103. Electric resistances. AUTOMATIC ELECTRIC LABORATORIES, Inc. March 5, 1951 [March 30, 1950], No. 5321/51. Class 37. A non-linear resistance comprises silicon carbide, a ceramic material and a silicone resin mixed and heated in a reducing atmosphere. The silicon carbide, kaolin and ball clay, are ground and mixed with silicone resin (polyalkyl siloxane resin) and toluol; the mixture is dried, powdered and pressed into discs which are heated to 1350‹ C. in first nitrogen and then hydrogen. Brass coatings are sprayed on each face of the discs, and leads attached by soldering, the final resistance being coated with phenolic varnish.
