Abstract
444,633. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and WIENECKE, B., 73, Honowerstrasse, Malusdorf, both in Berlin. Sept. 24, 1934, No. 27324. Convention date, Sept. 23, 1933. [Class 39 (i)] The cathode, a concentrating electrode which surrounds the cathode, the anode, and additional electrodes such as further anodes and deflecting plates, consist of conical tubes, or are mounted by means of conical tubes, all of said tubes being of the same shape so that they may be mounted one within the other with the interposition of insulating material. A cathode 1 consists of a platinum band provided with a spot of electron-emitting oxide and is mounted within a cup-shaped member 4 through wires 2, insulating tubes 3 and a plate 4<1> welded thereto. The wires 2 and the tubes 3 have a triangular or square cross-section to prevent their rotation. A Wehnelt cylinder 5 and an anode 8, in the form of conical tubes, and deflecting plates, mounted on tubes 11, 12, are registered with respect to each other by means of conical insulating tubes 6, 7, 9, 10, 13. The electrodes are secured together by means of bolts 15, an extension of which may be used for mounting the structure on the pinch. The insulating tubes may consist of glass, quartz, mica, porcelain, steatite, aluminium oxide, e.g. sintered corundum, magnesium oxide, beryllium oxide, zirconium oxide, or powdered mica mixed with an organic binder. The tubes may be glazed and may be provided with ribs or grooves to increase their insulation and to facilitate the degassing process. An indirectly - heated cathode may be used.
