Abstract
1,053,527. Cathode-ray tubes. ENGLISH ELECTRIC VALVE CO. Ltd. July 31, 1964 [Oct. 11, 1963], No. 40139/63. Heading H1D. In a cathode-ray tube with deflection beam control in which a transverse magnetic field deflects the beam across an apertured electrode, the magnet is shielded from the beam by an electrostatic screen and is positioned at or near the cathode at a region where the beam is substantially at cathode potential so that sensitive control of the beam may be obtained while the magnet can be near earth potential. As shown, two oppositely directed magnetic control fields are produced by flat spiral serially connected coils 5, 6 printed on an insulating sheet 4, the inner side of the sheet carrying an electrostatic screen in the form of a metallic comb-like deposit (not shown).
