Abstract

428,358. Valve accessories. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand-Ges. fur Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin) Jan. 28, 1935, No. 2791. Convention date, March 9, 1934. [Class 135] [See also Group XL] In an electrical discharge tube, such as a lamp, in which the filling of common gas is replenished from a reservoir through tubes 2, 10 by the raising of a float 8, by means of a magnet 9, to lower the level of a mercury or oil filling 7 and thus to allow passage of gas through the uncovered portion of a porous carbon plug 5, the liquid filling is replaced by a metal alloy, which is solid at ordinary temperatures, and is melted during operation by a heating element 11. The cone is inserted in a cement 4 and a bismuth-lead alloy, which melts below 100‹ C., may be used.
