Abstract

416,564. Oil-break switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Dec. 17, 1932, No. 35844. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 19, 1933]. [Class 38 (v).] Covers.-To prevent eddy-currents and consequent heating from being set up in the casings a of switches in the neighbourhood of the bushing insulators b<2>-d<2>, the latter are provided with flanged supports e of good conducting material such as bronze, and the supports e are interconnected by bars f secured by bolts g of good conducting material. Bars f are preferably arranged on both sides of the cover.
