Abstract
388,620. High-tension switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Soc. Generale de Constructions Electriques et Mecaniques Alsthom; 146, Avenue des Champs Elysees, Paris.) May 30, 1932, No. 15318. Convention date, May 29, 1931. [Class 38 (v).] Arc-rupturing devices.-On separation of a hollow cylindrical movable contact 3 from a fixed contact 4 within a chamber 2 that is closed by an insulating plate 7, the are formed vaporizes some of the oil, water, or other liquid within the chamber 2. Only when the contact 3 is sufficiently withdrawn to expose the outlets 9 above the guide 8 does the pressure in the chamber cause a stream of vapour and liquid to pass through the bore of the movable contact and extinguish the arc.
