Abstract

555,327. Resistors. ABBEY, A. (Ohio Carbon Co.). Feb. 12, 1942, No. 1882. [Class 37] [Also in Group XI] A resistor mounted in a lamp cap consists of a carbon resistance in the form of an annulus 30, with a terminal connection consisting of a wire 33 embedded in the annulus or wound round it and held in place by a conducting cement consisting of graphite and water soluble resin which sets on heating.
