Abstract

233,838. British Thomson-Houston Co., Ltd., and Whitaker, F. P. March 28, 1924. Coils and conductors.-Laminated magnetic slot-closing wedges are built of punchings made from a composite sheet comprising a strip of non-magnetic material and a strip of magnetic material secured edge to edge, each separate lamina comprising a magnetic sheet part b and a non-magnetic sheet part c. The laminae are perforated and strung on one or more insulating-rods e and are clamped thereon between thickened end-plates by ferrules. The magnetic portion b does not quite bridge the slot, the edge-to-edge joint being diagonal as shown.
