Abstract

663,737. Electromagnets. BRITISH THOMSON-HOUSTON CO., Ltd. March 5, 1948 [March 5, 1947], No. 6926/48. Class 35. Pole shaders in a laminated magnetic structure consist in substantially filling a pair of spaced-apart slots formed in said magnetic structure and transverse to the laminations with molten solder 7 so as to form with the laminations soldered joints of low resistance. Figs. 1, 2 show a plunger-type and a clappertype electromagnetic devices in which the pair of spaced-apart slots are filled with a highlyconducting material 7 which may be either molten solder or conducting bars and molten solder. Specification 290,208, [Class 35], is referred to.
