Abstract
1,086,869. Cathode-ray tubes. SYLVANIA ELECTRIC PRODUCTS Inc. June 29, 1965 [June 29, 1964] No. 27552/65. Heading H1D. A cathode-ray tube has a cylindrical or partcylindrical sleeve 29 surrounding the tube neck and provided with cut-outs 31, 33, 35 so as to serve as a template for locating spaced magnetic elements 23, 25, 27 in correct relationship with the electron gun or, in alternative embodiments, the elements may be located by markings on the envelope or by tapes or bands. The sleeve may be a slip-fit on the neck of the tube or attached to it by adhesive; the sleeve is referenced with respect to the tube base 17 and may be integral with it. The sleeve or tapes may be of plastic, paper, glass, cellulose or synthetic fibres. Additional cut-outs 37 are provided to facilitate heat radiation from the interior of the tube or to afford a view of the gun structure. For a colour tube the magnetic elements may comprise deflection yoke, dynamic convergence system, purity magnet structure and a blue lateral magnet assembly.
