Abstract
Method of making a cathode ray tube with a glass ampoule comprising a neck, a glass cone, and a glass window sealed thereto, ampoule that is surrounded on an area adjacent to the image area by a rigid strip that substantially does not exert pressure on the ampoule, the space between the strip and the ampoule being filled with a solid filler, characterized in that the strip comprises a single profiled metal ring, one end of which is adapted to the shape of the image area of the tube but whose opening is larger than the image area actually used, while the other wider end is continuous in a substantially cylindrical part whose opening is larger than the larger cross-section of the ampoule, which band is carried around the ampoule from the side of the window and placed, together with the ampoule, in the cupped cavity of a matrix, being surrounded the part of the window that must remain uncovered erta by a sealing ring present in the cavity of the matrix, while the blister rests on the edge of the smallest opening of the belt, after which a filling is poured into the space between the belt and the matrix and, if desirable in the space between the belt and the blister until the filling inside and outside the belt is approximately flush with the upper surface of the matrix and, after the filling has partially hardened, the remaining space between the blister and the belt is completely filled with a filling material.
