Abstract

541,596. Cathode-ray tubes. BAIRD TELEVISION, Ltd., HAMBURGER, G. L., and PEIRCE, H. S. June 21, 1940, No. 10696. [Class 39 (i)] Magnetic deflecting means for electron discharge tubes consist of a pair of substantially elliptical coils 5, 6 wound progressively from a single wire and disposed with their major axes at an angle to one another, and their minor axes coincident, parallel, or at a slight angle. The coils are preferably interwound either layer by layer, or turn by turn. For deflection in two directions, two pairs of coils are used, preferably one within the other and formed into a single structure. Specifications 528,801 and 530,523 are referred to.
