Abstract

357,002. Leading - in wires for electric-discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Nov. 14, 1930, No. 343348. Convention date, May 31. [Class 39 (ii).] The leading-in wires for the electrodes of an electric discharge tube are sealed into ferrochromium tubes 10 which are sealed through glass bushes 11 into a ferrochromium disc 2. The wires are separated from the tubes 10 for the greater part of their length to increase the cooling effect.
