Abstract

608,742. Thermionic valves. PHILIPS LAMPS, Ltd. March 19, 1946, No. 8418. Convention date, Aug. 8, 1941. [Class 39 (i)] The electrode supports 2 of a discharge device are connected to the lead-in wires 5 by one or more flexible connections 4. The thickness of 2 and 4 throughout their length is less than the width of the aperture in the mica 1 through which the support passes, thereby avoiding the necessity of welding to the supports 2 after mounting.
