Abstract

285,843. M³ller Akt.-Ges., C. H. F. Feb. 22, 1927, [Convention date]. Vacuum tubes. - A valve has a cathode, an anode, and two or more grids, oxide or other insulating layers being interposed between the wires of separated grids. The wires may be twisted together and the stranded wire wound to a helix. The wires in each grid may have separate leading-in conductors.
