Abstract

333,837. Silberstein, I. Dec. 18, 1928, [Convention date]. Resistance coatings.-A layer of carbon &c. is applied to an insulating base, such as a ceramic rod and covered with a layer of artificial resin or other permanent varnish (not wax); the covering layer, carbon layer and insulating base are then all ground away till the required resistance is obtained. In the arrangement shown the coated rod 12 is mounted in end contact 10 in a lathe and current is passed through it and through a galvanometer 8. A helical groove 4 is then cut in it by means of a traversing grinding disc 9 until the resistance reaches the required value.
