Abstract
175,258. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Feb. 9, 1921, [Convention date]. Vacuum tubes.-A tube, for use as a relay or amplifier, and containing a rare gas in which a glow discharge is produced only at the cathode, has one or more control electrodes mounted in close proximity to the anode and maintained at a relatively small negative potential with regard to the anode. Argon, neon or other rare gases or mixtures thereof may be used as the filling. The anode and control electrode may each consist of a coil of iron wire of the same diameter, in the common axis of which the cathode, in the form of a pin or small plate of magnesium, is arranged. The potential between the anode and cathode may be 120 volts, and the potential of the control electrode may be 20 volts or less below that of the anode.
