Abstract

1421296 Electric contact brushes INSTITUT MEKHANIKI METALLOPOLIMERNYKH SISTEM AKADEMII NAUK BELORUSSKOI SSR 7 Feb 1973 6003/73 Heading H2A A brush comprises conducting metal foil laminae 1 and intermediate adhesive layers 2 having a base of polymeric binder material, e.g. a thermo-reactive polymeric resin such as polyvinyl-furfural, epoxide phenol-formaldehyde or furan. Layers 2 may contain dispersed colloidal metal particles for improving the conductivity, and also fluorplast, graphite, molybdenum disulphide, niobium diselenite &c. for improving the frictional characteristics. A brush (Fig. 2, not shown) may also be formed by winding a foil strip (1) and an adhesive (2) into a coil shape, some layers in the coil having lobes (3) for connection to current leads.
