Abstract

261,816. British Thomson-Houston Co., Ltd., Whitaker, F. P., Martin, R. I., and Robinson, E. E. July 27, 1925. Coils and conductors. - Magnetic slot wedges are formed of composite material made from laminae of cotton, asbestos &c. bonded with synthetic resin or other binder, magnetic material in powdered or wire form being interposed between the laminae and the whole pressed into the requisite shape. As shown, Fig. 1, the wedge is made from a strip of magnetic cloth 1, and a strip of cotton or other woven fabric 2 bonded with synthetic resin &c., the strips being rolled together and thereafter subjected to heat and pressure.
