Abstract

1424366 Colour picture tubes RCA CORPORATION 17 May 1973 [17 May 1972] 23631/73 Heading H1D A frame for supporting the shadow mask of a colour picture tube comprises four sections 30, 32, 34, 36 each having end portions 46 which, when the sections are assembled to form a rest. angle, overlap the end sections 46 of the two adjacent sections to which they are secured by, for example, spot welding. All the interfaces of the overlapping end sections lie parallel to the screen of the tube and are preferably coplanar. Each section has an L-shaped cross-section.
