  • Patent number: 7534966
    Abstract: A printed circuit board (PCB) edge connection structure formed by a first PCB having one or more electronic components and printed circuitry provided thereon and a second PCB, having one or more edge contact pads provided thereon, attached to the first PCB and covering an area on the first PCB into which a portion of the printed circuitry extends. The resulting structure maximizes the utilization of the surface area on the first PCB for printed circuitry, thus, reducing the overall size of the end product.

  • Patent number: 4767694
    Abstract: The invention relates to a method of preparing a varnish blanket. Instead of a proof being used for pre-location of required varnish-free zones on a blanket for blanked-out in-line varnishing in rotary presses, the zones required not to be varnished are transferred by means of a reference copy, and after physico-chemical pretreatment adapted to the surface properties of the blanket, to a blanket stuck to a support plate. In addition to polyvinyl alcohol copying layers or coatings sensitized by bichromate, wipe-on copying layers sensitized by diazo salts are suitable, a positive or negative original being copied by direct contact in known manner onto a blanket thus pretreated. The zones required not to be varnished can therefore be preformed by cutting out the top layer of the blanket.

  • Patent number: 4576904
    Abstract: More effective camouflage patterns are generated by use of certain known tographic and photooptical contrasting procedures to obtain more desirable positive high contrast images representative of the natural background areas in which military equipment is intended to operate. Generating and using such camouflage patterns constitute a unique and novel use of such images which have predetermined color tones or values assigned to varying degrees of light, intermediate and dark contrast areas. The patterns may be applied onto the equipment in any of several conventionally known manners, thereby enabling otherwise artistically unskilled field soldiers to more effectively camouflage their equipment.

  • Patent number: 4478639
    Abstract: An apparatus and method of producing a parallax stereogram, i.e., free vision stereogram, and particularly for the accurate registration of a plurality of film images in order to ensure stereographic reproduction. The images on a film strip are optically viewed to establish homologous points for each film frame image. In one embodiment two images are optically superimposed to establish a stereo base distance. Each film frame is marked in accordance with the homologous points or stereo base distance. The marking may be mechanical or optically generated. Each film frame is thereafter aligned or sensed while in an enlarger, the marks establishing the accurate registration of eaach frame. Each film frame is exposed onto a photosensitive material using a movable line grid. A lenticular screen is superimposed over the developed picture to form the stereoscopic photograph.

  • Patent number: 4361634
    Abstract: A multilayer printed circuit board structure and a method for generating artwork masters for the manufacture thereof. The multilayer board comprises universal internal layers of predefined circuit patterns. The internal layers include power and ground planes, and for boards having high component and circuit density, one or two signal crossover layers with short, equal-length runs oriented transversely to the runs of an adjacent outermost signal layer. Electrical interconnections between layers of the circuit board are effected by interlayer conductors such as pins or plated-through holes at predefined locations. The artwork masters for the outermost layers are generated utilizing two degrees of layout precision. A universal layout master having interconnection pads and parallel circuit runs extending across the entire surface of the board is first prepared using a high degree of precision.
