Abstract
773,384. Mountings for cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 3, 1955 [March 6, 1954], No. 6310/55. Class 40(7) A rectangular screen metal cone cathoderay tube is supported in a cabinet by means of a ring shaped rigid frame which surrounds the conical part of the tube adjacent the image screen and which is itself surrounded and supported by a ring shaped supporting member secured to the cabinet. The latter member comprises a mask 9 (formed of insulating material) inside which the frame 17 (formed of metal or of insulating material), which grips the cone of the tube only at the positions 11a, Fig. 1, is adjustably retained (1) by means of screws 21 passing through elongated slots in the flat portion 15 of mask 9 (as shown in Fig. 2); (2) by means of screws 25 bearing against an abutment in the mask 9 the tube being urged towards the mask by means of a resilient member 27 or (3) by means of screws 29 threaded into an abutment in the mask. In the embodiments of Figs. 2 and 3 the' tube is screwed to the frame by means of hooks 19 and an elastic cord or tube 23 provides a dust-tight seal and in the embodiment of Fig. 4 a further elastic member 33 is provided between the tube screen and the edge of the mask.
