Abstract

493,602. Cathode-ray tubes. ALLAM, P. S. (Schlesische Spiegelglas-Manufactur C. Tielsch Ges.) March 25, 1938, No. 9220. [Class 39 (i)] The end wall b of a Braun tube is formed separately from the metal or glass body a, is spherical, and ground and polished plane parallel; its curvature may be such that after mounting on the body and evacuation it flexes and is substantially flat. The edge may be ground vertically to the surface as shown at c, or the edge may be made of two surfaces at right-angles as shown at c<1>. The flanged end of the body is shaped to correspond and jointing material may be interposed. Grooves may be formed in the flanged end and /or in the edge of the end wall.
