Abstract: 481,434. Cathode ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and MYERS, L. M. Aug. 10, 1936, No. 22035. [Class 39 (i)] In a cathode - ray tube, which is provided with an incandescent screen, the heating of the elemental areas of the screen is continued after impingement of the beam on the respective areas by secondary electron bombardment which is initiated by the impingement of the beam on the areas. A tube comprises an electron gun 1, electrostatic or electromagnetic deflecting members 2, 3 and an incandescent screen 5 which is formed by pressing into a fine tungsten mesh a paste which consists of tungsten powder, colloidal graphite and a binder of silicate of potassium or sodium. A highfrequency voltage is applied through a coil 7 between the screen 5 and a tungsten mesh 6 in such manner that secondary electrons released from the screen are accelerated to the mesh to generate further secondary electrons which are in turn accelerated to the screen. The electron multiplication is preferably equal to or less than unity so that the electron bombardment of each element will gradually cease before the main electron beam impinges thereon. A concentrating magnet 8 is provided. In another form, the high-frequency voltage is applied between the screen 5, Fig. 5, and a cylinder 6a and a further cylinder 6b, negatively biassed, is provided. The focusing magnet 8 generates a field which is such that the secondary electrons travel in helices the radii of which is not greater than that of the elements of the screen. The electrodes may be mounted within a tube 9 formed of silica or of the glass known under the Registered Trade Mark " Pyrex " and coated with colloidal graphite ; it is stated to reduce space charge.
