Abstract

296,314. Siemens & Halske Akt.-Ges. Aug. 27, 1927, [Convention date]. Vacuum tubes. - The leads 6, 7 for a single elongated hairpin filament cathode 3 are arranged opposite to one another in the envelope and perpendicular to the axis of the tube. The cathode is supported by rigid conductors 4, 5 connected through the fiexible leads 6, 7, with rods 9 which are fixed to glass projections 10 on the envelope 1 by metal parts 12. An anode 2 surrounds the cathode.
