Abstract

198,322. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. May 27, 1922, [Convention date]. Leading-in wires. - In electric lamps and vacuum tubes wherein leading-in wires 3, 4 for heavy currents are attached to discs 2 sealed within tubular extensions 1 of the glass containers, the discs are made of chromium-iron alloy having a coefficient of expansion approximating to that of the glass. The parts of the conductors near the disc are preferably of nickel.
