Abstract

927,025. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 14, 1961 [Nov. 17, 1960; Nov. 1, 1961], No. 40708/61. Class 39 (1). [Also in Group XL (c)] The hood 1 surrounding the deflection coils of a television display tube is formed from synthetic resin in which is included in an annular zone 9 material such as barium ferrite so that by magnetization of selected parts of this zone some of the correction magnets 3 and the adjustable magnets 7 may be dispensed with.
