Abstract
479,045. Variable resistances. STEATITMAGNESIA AKT.-GES. July 29, 1936, Nos. 21036 and 21037. Convention dates, July 29, 1935 and Aug. 1, 1935. [Class 37] On the reverse side of the base-plate carrying the variable resistor there is provided a series resistance in curved or zigzag form and consisting of finely divided material suspended in a binder which can be hardened, this resistance being fixed in value for the purpose of giving well-defined initial and final values to the total resistance. The main resistance track b is secured by rivets c and one end is provided with a layer i of precious metal burnt or sprayed thereon. The series resistance g may be extended by a pin h joining it with the terminal connector e<2>. The slide on the main resistor b is provided with a contact track d. Fig. 3 shows stop mechanism which is metallic, the contact part r being insulated at q from the stop arm o which engages the fixed stop l, preferably over a surface contact. Fig. 6 shows a form of contact l<1> adjustable in lugs t struck up from the base-plate. The Specification as open to inspection under Sect. 91 comprises also a resistor, Fig. 7 (Cancelled), having a high-resistance layer v and a layer w having a relatively low ohmic value, the boundary between the two layers being shaped as shown to produce a smoother variation of resistance. More than two layers may be provided. This subject-matter does not appear in the Specification as accepted.
