Abstract

560,490. Cathode-ray tubes. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Feb. 6, 1942, No. 1619. [Class 39 (i)] Beam deflection valve comprises a single curved reflecting electrode 9 which corrects spherical aberration and two collecting electrodes 12, 13 which may be directly connected to the deflecting electrodes 8 to form a high frequency oscillator. In an arrangement described with reference to Fig. 3 (not shown), the valve may be used as a mixer the incoming signals being applied to a beam control grid, local oscillations to one of the deflecting plates, and the output signal taken from the other deflecting plate. Specification 471,250 is referred to.
