Abstract: The combination includes a cathode-ray tube in operational relationship with a magnetic deflection yoke. A platform is rigidly adhered to fixed areas on the external surface of the tube with a hardened adhesive material. The hardened adhesive material provides the sole support for the platform and a yoke mounted thereto. The novel method includes positioning a platform against a tube and injecting a first hardenable liquid adhesive material between at least portions of the positioned platform and the tube. The first adhesive material is permitted to harden and to fix the platform on the tube. A housing for a magnetic deflection yoke with the yoke therein is positioned adjacent the fixed platform, and the position of the housing is adjusted with respect to the fixed platform to obtain a desired operational relationship of the yoke and the tube. The housing with yoke therein is then mounted to the platform in the desired operational relationship.

Abstract: An internal magnetic shield of generally truncated pyramidal shape conforming generally to the inner wall of the funnel of a rectangular shadow mask type color picture tube is made up of four pre-annealed trapezoidal pieces of magnetic sheet metal assembled and attached together by overlapping flanges integral with the non-parallel sides of the pieces. The larger end of the shield is attached to the shadow mask frame by integral flanges on the long sides of the trapezoidal pieces. The sheet metal of the shield is annealed either before or after being formed into the trapezoidal pieces, but before assembly and attachment of the pieces together.
