Abstract

386,326. Oil-break switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Prince, D. C. ; 1424, Wendell Avenue, Schenectady, New York, U.S.A.) July 10, 1931, No. 34899/32. Convention date, July 10, 1930. Divided on 386,322. Drawings to Specification. [Class 38 (v).] Arc-rupturing devices; springs, arrangement of; switches, actuating.-The Specification describes an oil or other liquid-blast switch in which a number of series-connected breaks are arranged in an insulator bushing, and means are provided for simultaneously opening all the breaks and for producing a flow of liquid thereacross. The switch is the same as that described and illustrated in Fig. 3 (Cancelled) of Specification 386,322 from which the present Specification is divided.
