Abstract
527,893. Cathode-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 22, 1939, No. 12193. Convention date, April 25, 1938. [Class 39 (i)] In order to diminish the effect of one pair of deflecting plates in a cathode-ray tube on deflection produced by the other pair of plates one plate of a pair is provided on the edge nearest the other pair with two projections extending towards and overlapping the other plate of the pair and enclosing the ray. The projections 14, 15 are, as shown, preferably attached to a plate of the pair more remote from the cathode and their dimensions in the axial direction of the tube are small compared with those of the plates. When one plate 12 of the pair is at constant potential and the other, 13, at a varying potential, the projections should be on the plate 13. The projections may be in one piece with the plate, or welded thereto, or formed as clips.
