Abstract

411,738. Making dynamo &c. cores. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Wry, T. A. ; 409, Broadway, Lynn, Massachusetts, U.S.A.) Oct. 20, 1933, No. 29080. Convention date, Oct. 26, 1932. [Class 83 (ii).] Cores for dynamoelectric machines are made from a strip S of magnetic material by severing along lines 8, 9, Fig. 2, to form overhanging teeth 5 with coil slots between the teeth, separating the strips and bending edgewise to helical form and annealing. Specifications 406,951 and 412,472 are referred to.
