Abstract
813,238. Cathode ray tubes. STANDARD TELEPHONES & CABLES Ltd. Aug. 30, 1957 [Sept. 4, 1956], No. 27409/57. Class 39(1). In deflecting-coil arrangements with yokes members of ferromagnetic material, the yoke member 1, Fig. 7 is provided at one or both ends with cut-out portions 7 through which the coil windings 4 are passed so that the front end of the yoke member may be located close to the cone of the tube and windings not participating in the generation of the useful field are screened from the deflection space by the protruding end of the yoke member. The yoke member 1 may be flared at one end, or have a separate flared piece 1a, Fig. 15, to fit over the cone of the tube. The coils may be jacket-core for one direction of deflection and toroidal for the other, and cut-outs for the toroidal coils may be formed from one of the joints separating the parts 1, 1a.
