    Abstract: The method includes supporting a panel of a cathode-ray tube in a given position, placing on the inner surface of the faceplate a flexible spacer having a predetermined thickness related to the desired spacing q between an aperture mask to be assembled with the panel and the faceplate, and then, placing the mask against the flexible spacer. The spacer is forced against the inner surface of the faceplate and the mask is forced against the spacer. The mask, frame and frame supports are assembled and detachably mounted on the studs of the panel. In a particular form of the method, the mask is detachably mounted in the panel by welding the support members to the frame and by welding the mask to the frame while maintaining the mask conformed to the desired contour at the desired spacing q.

    Abstract: A cathode-ray tube includes a rectangular faceplate which has an exterior surface having curvature along both the minor and major axes. The exterior surface of the faceplate includes a rectangular contour near its periphery which substantially lies in a plane which is perpendicular to the central longitudinal axis of the tube.

    Abstract: An improvement is made in a color picture tube that includes an evacuated envelope having a rectangualr faceplate panel with major and minor axes, wherein a central longitudinal axis of the tube passes through the center of the faceplate perpendicular to the major and minor axes. The faceplate panel includes a shadow mask welded at various points including its corners to a peripheral frame mounted therein. The frame is L-shaped having a first flange approximately paralleling the central longitudinal axis and a second flange extending toward and approximately perpendicular to the central longitudinal axis. The tube improvement comprises the frame having truncated corners wherein the first flange at each of the frame corners is straight, flat and acutely angled with respect to both the major axis and the minor axis. A peripheral portion of the shadow mask conforms to the shape of the first flange and is telescoped thereon. The corner welds attaching the shadow mask to the frame are located approximately at the centers of the straight and flat portions of the truncated corners.

    Abstract: In the novel method, the widths of the parallel luminescent stripes of a luminescent viewing screen are scanned by a beam of ultraviolet light whereby the stripes are excited to emit light along the path of scan. The emissions of the light in an identifying spectral band are sensed with respect to the position of the light beam on the screen and converted to a train of electrical signals. Then, the average width of the stripes identified by the spectral band is calculated from the distance over which the intensities of the signals are continuously above an assigned value.
