Abstract

576,204. Cathode-ray tubes. CINEMATELEVISION, Ltd., and LANCE, T. M. C. April 26, 1944, No. 7822. [Class 39 (i)] A cathode-ray tube comprises a metal body with openings to receive a side tube containing the electrodes and a transparent plate through which the image is viewed or projected. In the form shown, 10 represents a lens system for projecting the image on to a viewing system, or the flat glass plate 5 may be replaced by a curved plate co-operating with a concave external mirror and an aspherical correcting plate. The screen 7 may be separate from or mounted on the plate 6 secured to or integral with the metal case 1 and may have a flat or convex surface.
