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.

Abstract: A reciprocating pump piston includes a piston rod which is adapted to be disposed within a cylinder. A piston hub is secured to the piston rod and is adapted to be reciprocated thereby within the cylinder. The hub includes a flange portion having a cylindrical outer periphery of slightly smaller diameter than the inner diameter of the cylinder and a generally cylindrical body portion having a diameter smaller than the flange portion. An annular piston seal ring is disposed about the hub body portion. The seal ring includes an inner leg disposed in mating relation with the body portion and an outer leg defining an annular sealing lip which yields radially inward upon insertion of the hub into an associated pump cylinder. Yielding of the outer leg is to a predetermined extent sufficient to block dislodgement of the inner leg from mounted association with the hub body portion. Also provided is an annular anti-extrusion member disposed around the hub body portion intermediate the seal ring and the hub flange portion. The hub body portion includes a circumferential groove adjacent the forward end thereof, and the seal ring inner leg includes portions which closely fit into the groove.

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: Improvement is provided in the appearance of a color picture type cathode-ray tube including rectangular faceplate with an exterior surface having curvature along both the minor (Y-Y) and major (X-X) axes. At least in the center portion of the faceplate, the curvature along the minor axis is at least 10 percent greater than the curvature along the major axis. Points on the exterior surface near the ends of the major axis, at the edges of the screen, lie in a first plane (P1) perpendicular to the central axis (Z-Z) of the tube; points on the exterior surface near the ends of the minor axis, at the edges of the screen, lie in a second plane (P2) which is spaced from and parallel to the first plane; and points on the exterior surface near the ends of the diagonals of the rectangular faceplate, at the edges of the screen, lie in a third plane (P3) which is spaced from and parallel to the first plane. The three planes are spaced from the center portion of the faceplate in the order of second plane, first plane and third plane. Further relative dimensions are detailed.

Abstract: The present invention is an improvement in a method of screening a line screen slit mask color picture tube. Such method includes coating a faceplate panel of the tube with a photosensitive material, inserting a slit shadow mask into the panel and exposing the photosensitive material by passing light from a line light source through the slits of the mask. The improvement comprises positioning a generally cylindrical shaped lens between the line light source and the faceplate panel during exposure of the photosensitive material. The longitudinal axis of the lens is oriented perpendicular to the longitudinal axis of the line light source. Because of the presence of the lens, the images of the line light source projected through the slits of the mask onto the photosensitive material at locations off the major and minor axes of the panel are rotated toward parallelism with the minor axis thereby resulting in exposure of straight smooth lines on the photosensitive material.
