Abstract

378,535. High-tension switches. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION, WHITNEY, W. B., WEDMORE, E. B., and CASSIE, A. M., 36, Kingsway, London. May 9, 1931, No. 20433/32. Divided on 378,493. Drawings to Specification. [Class 38 (v).] Relates to oil or gas break switches in which a blast of fluid is forced across the arc at break by a piston or equivalent pumping member. The description is substantially the same as that of Fig. 1 of Specification 378,493. Specifications 278,764 and 330,616, [both in Class 38 (v), Electric switches &c.], are referred to.
