Abstract
426,039. Liquid - seal valves. LEHMANN, W., 52, Westfõlishestrasse, Halensee, Berlin. Sept. 6, 1934, No. 25691. Convention date, Sept. 26, 1933. [Class 135] [See also Group XL] Gas from a reservoir 22 is fed to a mercury - vapour electric discharge device through a valve controlled by a coil 28 itself controlled by a vacuum meter. A porous plug 24 covered by mercury in a U-tube 26 is exposed to allow the passage of gas when the iron core 27 is raised by the coil 28.
