Abstract: A combination including a cathode ray tube, magnetic filed producing means and a body of cured polymeric material holding the yoke in a fixed position on the tube. There is a parting layer of thermoplastic material between the cured polymeric body and at least one of the tube or the yoke. The parting layer of thermoplastic material softens at a temperature above the operating temperature of the yoke and below the temperature at which the yoke is damaged.

Abstract: A cathode-ray tube including, on its viewing surface, a glare-reducing coating composed of a lithium silicate material and carbon particles. The novel method comprises: (a) warming the surface of a glass support to about 30 DEG to 100 DEG C, (b) coating the warm surface with an aqueous solution containing about 1 to 10 weight percent of a lithium-stabilized silica sol and a sufficient proportion of carbon particles to produce the desired reduction in light transmission, (c) drying the coating, and then (d) heating the dry coating at about 150 DEG C to 300 DEG C.
