Abstract

307,629. Walker, Hunter, & Co., Ltd., and Walker, J. March 12, 1928. Wire resistances, mounted on flat or curved surfaces.-A grooved former 1 for holding heating resistances has two series of coplanar parallel groove 2, 3 therein, the grooves of one series alternating with those of the other. The connecting channels at the ends of the grooves are in two different planes so that the resistance 6 in one series may bridge that in the other without contact.
