Abstract
1,012,670. Colour television tubes. RADIO CORPORATION OF AMERICA. June 24, 1963 [July 10, 1962], No. 25113/63; Heading H1D. A magnet holder for the beam convergence system of a three-gun colour television picture tube comprises a circular array of plastic magnet holding sections 12, Fig. 1, joined together by plastic, resilient spring-like sections 14. Each section 12 has holes 34 for receiving the legs of a U-shaped magnetic core 46 which carries the vertical and horizontal dynamic convergence coils 48, 50. The core 46 is held in position by a spring clip 56 engaging the inturned lips 42 of arms 40 of the section 12 at its ends. An extension 62, Fig. 2, of the spring clip 56 has spring arms embracing an H-shaped plastic beam 54 in which are mounted, at its lower end, one or two rod-shaped permanent magnets 52, 52<SP>1</SP> for providing static convergence.
