Abstract: An assembly for use in propelling electrode darts toward a distant target is deployed in an electrical discharge weapon. The assembly comprises a cartridge having a u-shaped channel terminating in apertures through which wire-tethered darts are propelled. Propulsion is achieved relatively efficiently using the sudden release of compressed gas from a sealed storage tank in response to penetration by a conical penetrator forced by an electrically-induced ignition of a pyrotechnic material to accelerate toward and penetrate the tank at an axial surface. The conical shape of the penetrator and the axial penetration of the tank produces a precisely symmetric rush of gas into a relatively confined volume including the dart channel to propel the darts toward the target in an efficient manner. Paper stickers may cover the dart exit apertures to permit initial pressure buildup before the darts penetrate the stickers as they are propelled toward the target.

Abstract: A unitary projectile for an immobilization weapon and tethered by two electrical wires, has a plurality of electrical contacts including several contacts dispersed in a spaced pattern around the projectile after target impact. The pattern of several contacts substantially increases the probability that if the projectile hits the target, an immobilization circuit through the target will be completed. The deployment of the contacts occurs as a result of the sudden deceleration of the projectile when it impacts the target. This simplifies the deployment as well as the projectile configuration and likely reduces the risk of misactivation or an ill-timed activation of the second contacts. In a preferred version of the disclosed embodiments, there are preferably four contacts dispersed in a symmetrical arrangement around the projectile.

Abstract: A system for standardized printing of CRT screens is disclosed. A preferred embodiment utilizes a standardized photoexposure stencil made without the use of a shadow mask aperture pattern and projection printing. The stencil is then placed in proximity to the screening surface during exposure. Front panel and mask support topography preparation methods and apparatus are disclosed, as are means and methods for compensating for variations among panel assemblies utilized in standardized printing of the screens. The system thereby produces high resolution screens which may accept interchangeable shadow masks.

Abstract: A surface discharge-type plasma display panel having a glass plate including an X-electrode base that is positioned on the glass plate, a plurality of X-electrodes that are inserted vertically into the glass plate, and Y-electrodes that are each arranged around the corresponding X-electrodes in the shape of a "C" or an "O". This structure reduces the possibility of a dielectric breakdown.

Abstract: In recovering flat glass faceplates used in color cathode ray tubes (CRTs) where the CRT is rejected during manufacture, the faceplate is cleaned for re-use with a high pressure vapor blast incorporation small particles in a slurry form. The particles may be comprised of small plastic beads or pellets, with walnut shells reduced to particle size on the order of 40-100 mesh and pressures in the range of 20-30 p.s.i. used in a preferred embodiment.

Abstract: An apparatus is disclosed for curing a defect in a grille formed on an interior face of a color cathode ray tube panel. The apparatus includes a support structure including a first rail member onto which is mounted a camera including a magnifying lens for viewing on a display monitor the grille of the panel. The panel is seated on a positioning apparatus which allows the panel to be adjusted such that the defect to be removed is centered on cross-hairs located on the monitor. The support structure includes a second rail member to which is mounted a laser apparatus which produces a beam of laser energy to remove the defect from the grille.

Abstract: A color plasma display panel making use of a multiple layer substrate includes a glass plate arranged with an inverse frusto-conical discharge space, an anode formed on the upper surface of the glass plate in the inner central part of the discharge space, a thin glass plate provided with a circular hole through which the discharge space extends in its position on the glass plate, three cathodes formed annularly in the inner surface of the thin glass plate at a regular angle with the anode as the center, an insulation substrate provided with a circular hole through which the discharge space extends on the thin glass plate and a front glass substrate arranged on said insulation substrate so that a R, G, B fluorescent substance may be formed at the bottom to confront with the three cathodes.

Abstract: The present invention relates to an apparatus for nonpressurized infusion brewing of a beverage, and especially tea brewed freshly from tea leaves, primarily adapted for use in vending machines. The apparatus includes a novel brew assembly comprising a frame, a carriage reciprocable along the frame between a brew position and discharge position. The carriage is driven between the brew position and discharge position by a motor driven crank pin mounted on a crank arm in which the crank pin is slidable in a transverse slot formed in the carriage. The carriage carries a brew cavity having an open top and bottom with externally extending guide pins mounted on opposed side walls. The brew cavity is mounted within the carriage and is normally biased towards a lower position.

Abstract: This disclosure depicts method and apparatus useful in fabricating a screen of a color cathode ray tube of the slot mask, stripe-screen type and more particularly method and apparatus for exposing a photosensitive coating on the concave inner surface of the faceplate of such a tube through a slot mask serving as an exposure master. Latent screen stripe images are formed whose width increases with increasing radial distance along the screen "pitch" axis perpendicular to the screen stripe images.

Abstract: This disclosure depicts method and apparatus for screening slot-mask, stripe screen type color cathode ray tubes particularly method and apparatus for improving screen stripe uniformity and edge definition. The method involves supporting a curved, approximately rectangular faceplate which has on its concave inner surface a photosensitive coating and which has supported adjacent its inner surface an exposure mask defining an array of columns of spaced slots oriented parallel to the minor axis of the faceplate. A line source of radiation actinic to said coating is supported on or near a central axis of the faceplate. The disclosed method includes producing a virtual image of the line source which appears, when viewed from off-axis points on the faceplate, to be rotated in a direction effective to decrease an unwanted rotational displacement of the mask slot images induced by the relative geometry of the line source, the mask slots and the faceplate inner surface.

Abstract: Apparatus for use in a lighthouse station for automatically maintaining the output of the light source at a predetermined level comprises a chamber for supporting a cathode ray tube face panel and a source of actinic energy located in the chamber. An adjustable controller is employed for energizing the source. A light translator in the form of a quartz rod is disposed adjacent the energy source for monitoring its output. A light responsive device, coupled to the light translator, derives a control signal representative of the instantaneous energy level of the light source. Finally, means responsive to the control signal serves to actuate the controller to maintain the output of the source at a predetermined level.
