  • Patent number: 5023509
    Abstract: A color cathode-ray tube-yoke combination comprises a color cathode-ray tube having a glass envelope and a yoke for producing magnetic fields positioned thereon. At least one semi-flexible corrective magnet is attached to a curved portion of the envelope. The novel corrective magnet is improved over prior corrective magnets by the inclusion therein of at least one portion of reduced thickness which increases the flexibility of the corrective magnet to provide conformity to the curved surface portion of the envelope.

  • Patent number: 4165396
    Abstract: In a method for preparing a luminescent screen which includes depositing a light-absorbing matrix upon a support, depositing a phosphor-particle layer on the matrix and support, and then coating the phosphor-particle layer with a film of organic polymeric material, the steps for salvaging the support and matrix substantially undisturbed, while substantially entirely removing the overlying material. In the method, the overlying material is contacted with an alkaline aqueous solution until the organic polymeric film is at least partially solubilized. Then, the overlying material is substantially entirely flushed away.
