Abstract

351,367. Transformers ; reactors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London-(Assignees of Unger, M. ; 51, Lincoln Terrace, Pittsfield, Massachusetts, U.S.A.) Oct. 21, 1930, No. 31558. Convention date, Oct. 21, 1929. [Class 38 (ii).] The spacers 14 used for separating the inner laminations of transformer, reactor, and like cores 10 to provide a ventilating duct 12 are held in position by tongues 15 struck up from the metal of the laminations. The tongues may be of tapered form so as to engage securely the spacers when the latter are pressed on.
