Abstract
403,600. Liquid-break switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Aug. 19, 1933, No. 23186. Convention date, Aug. 20, 1932. [Class 38 (v).] In a water or other liquid break switch of the character disclosed in Specification 402,927, in which the fixed contact is arranged in an extinguishing chamber 1, which opens into or is situated within an outer expansion chamber having its axis arranged at an angle to that of the chamber 1, the expansion chamber is divided into two parts 2, 3 by a partition 4 having a spring or gravity-controlled non-return valve 5 which, so long as the movable contact 6 is within the chamber 2, allows gas and liquid to pass from chamber 2 to chamber 3, so preventing ionisation of the arc path and contamination of the switch surroundings.
