Abstract
601,022. Cathode-ray tubes. GENERAL ELECTRIC CO., Ltd., and HILL, R. T. J. Nov. 22, 1944, No. 23189. [Class 39 (i)] A cathode-ray tube of the kind having means for forming a circular trace has the central portion of the end wall inwardly cupped ; the inner surface of this cup is coated with an electrically conducting material such as graphite to provide the deflecting electrode, and the fluorescent screen occupies the annular portion of the end wall surrounding the cup. In a modification, the cup is formed wholly of metal, sealed into an annular glass end wall.
