Abstract: A dart board assembly for use in an electronic dart game. The assembly includes a frame having an inner end, an outer end, and an axis and including a generally annular central wall defining a bull's-eye. The frame includes a number of radial walls extending away from the central wall and a circular wall, concentric with the central wall, with each of the walls extending between the frame ends and the walls defining the plurality of spaces. A target segment is disposed in each of the spaces and includes a target plate having a great plurality of closely spaced apertures for receiving the pointed shaft of a dart. The plate is shaped to engage an enlarged rib forming a constricted throat of its space to prevent movement of the target out through the outer end of the frame. Each target segment includes at least a pair of space legs extending from the target plate toward the inner end of the frame with each leg being engageable with a pair of the walls forming the frame.

Abstract: An improved process is disclosed for forming a series of electrically conductive path through-holes in a dielectric layer which is sandwiched between two electrically conductive layers by applying pressure to conductive overhangs in a conductive layer through and elastomeric surface.

Abstract: An electrostatic printing process is disclosed wherein a printing roll is formed by forming a latent magnetic image in a magnetic imaging member, decorating the latent magnetic image with a nonconductive magnetic toner to form a toner image, transferring the toner image to a conductive member and temporarily fixing the toner image to the conductive member. The toner image on the conductive member is electrostatically charged, while the charge is dissipated from the remaining area of the conductive member. The charged image of magnetic toner is decorated with an electrostatic toner comprising a colorant and a binder resin to form an electrostatic image which is transferred to a substrate. Pattern change is accomplished by washing off the fused toner from the conductive print roll and forming a new fused toner image on it.

Abstract: Process for preparation of improved surprint multilayer proof using at least three nonplanar nonsilver photoimaged elements, i.e., negative-working photosensitive element which are laminated sequentially to a support having a permeability to air of less than 0.1 cm.sup.3 /second, a peel adhesion value of at least 250 g/inch (98.48/cm) and a total luminous transmission not in excess of 25%, e.g., oriented polyethylene terephthalate film filled with polypropylene and/or with BaSO.sub.4 or TiO.sub.2. The surprints are useful as pre-press proofs.

Abstract: A telemetering system for a data transmission line having a sequence of repeaters controls sequential operation from a centralized single supervisory terminal. The supervisory terminal sends an interrogation signal forward to a first repeater which sends back an answer signal relating to the status of that repeater and also sends the interrogation signal forward to the second repeater. In addition, status answer signals received from said subsequent repeaters in the sequence are transmitted backward through the repeater chain to the supervisory terminal. Thus, each repeater acts on the telemetering channel as a bidirectional repeater, repeating forwardly the interrogation signal and repeating backwardly its answer and the answer of subsequent repeaters in the sequence. Eight status parameters are detected at each repeater and monitored at the supervisory terminal.

Abstract: A process for manufacturing an enriched fructose syrup, which is characterized in that dextrose is crystallized from a relatively high solids feed syrup containing fructose and dextrose and then another relatively dilute (or lower solids) fructose containing diluent syrup is added to enhance separation of the dextrose crystals from the mother liquor.Process can be adjusted to yield dextrose monohydrate or anhydrous alpha dextrose crystalline product in addition to an enriched fructose syrup.

Abstract: A method for determining a parameter that characterizes the cross sectional shape of a running multilobal filament or yarns thereof, by light scattering analysis. The analysis is based on detecting and measuring the intensity of light scattered from the yarn in the plane of the incident beam which is oriented perpendicularly to the longitudinal axis of the yarn. By comparing the intensity of the scattered light with previously measured standard values for the particular yarn geometry being measured, using correlation techniques, the average cross sectional shape parameter can be determined.

Abstract: Certain N,N'-ethylenebisamides and N,N'-diadipamides added to ethylene/vinyl acetate dipolymers, terpolymers of ethylene with carbon monoxide, copolymers of ethylene with methacrylic acid, copolymers of ethylene with methyl methacrylate, and terpolymers of ethylene with n-butyl acrylate and carbon monoxide remarkably reduce the tendency of polymer pellets to block. Free-flowing copolymer pellets can be handled without blocking and moved more quickly through the packing equipment and can be stored for extended periods without blocking. Copolymer pellets containing these additives can be packed into large containers and shipped without blocking. The preferred additive is N,N'-ethylenebisoleamide.
