  • Patent number: 4657400
    Abstract: A device for mixing, milling or kneading feed materials, such as plastics and fillers, including a pair of spaced apart upper and lower discs defining therebetween a mixing zone. Each disc has an operating surface and is adapted so that by rotation of one of the discs, a relative motion between the two operating surfaces may be maintained. A collecting ring with a groove extending along the inner surface thereof is provided around the periphery of the mixing zone to define an annular passage which is in fluid communication with the mixing zone and which is open at one end and closed at the other end. By rotation of one of the discs, the mixed product is collected in the passage, displaced therethrough and discharged from the open end portion or scraped off at the closed portion for recovery.

  • Patent number: 4624821
    Abstract: A process and apparatus for the blow molding of oriented, hollow containers from tubular parisons in which a tubing of plastic material at a suitable orientation temperature for the material is passed by a puller assembly to a cutter assembly. The free end of the tubing is grasped by a parison transfer assembly, after which parisons are cut from the tubing by the cutter assembly and positioned by the transfer assembly for placement within blow molders. The first of two blow molders moves toward the tubing centerline from a molding position to receive a parison. The parison transfer assembly is extended vertically to place the parison within the molding cavity of the open blow molder. The upper end of the parison is grasped by a tube clamp, and as the parison transfer assembly retracts, the parison is stretched prior to molder closure. The closed blow molder returns to its molding position to complete the blow molding of a finished, oriented container.

  • Patent number: 4614586
    Abstract: A semipermeable membrane having a surface comprised of a poly(arylacetylene) having at least a part of its benzene nuclei introduced with sulfonic acid groups. The poly(arylacetylene) is represented by the following structural formula (I): ##STR1## wherein X stands for Cl, Br or CH.sub.3, R stands for H or CH.sub.3 and n is a positive integer. The semipermeable membrane may be obtained by subjecting a membrane formed of the poly(arylacetylene) of the formula (I) to sulfonation conditions or by sulfonating the poly(arylacetylene) of the formula (I), and forming the sulfonated product into membrane.

  • Patent number: 4586008
    Abstract: A passive integrator capable of correctly providing outputs with risetimes as short as 250 ps. An outer conductor has coaxially mounted therein a short length of an inner conductor so as to constitute a very low impedance transmission line. The short length and low impedance of this transmission line cause it to behave as a capacitor. Electrostatically shielded resistors are connected to both ends thereof by a center conductor. Compensating capacitors coaxially mounted therewith may be employed.

  • Patent number: 4560088
    Abstract: A vending machine having a plurality of helically-wound dispensing coils with merchandise items disposed between adjacent coil convolutions is provided with a coil operating system movable along X-Y axes. A first drive motor rotates a vertically-oriented shaft to reciprocate a traveler movable thereon and supporting a horizontally-disposed member. A second drive motor and a counter-balancing weight, mounted adjacent to the ends of the member, are interconnected by a second shaft rotatably secured to the second motor and the weight. A horizontally-movable traveler carrying a dispensing coil actuator reciprocates along the second shaft. A control unit responds to signals from a coin-operated merchandise selector to move both travelers, vertically and horizontally, respectively, to position the actuator adjacent to the dispensing coil for the selected item. Operation of the actuator motor rotates the coil to dispense the item.

  • Patent number: 4494257
    Abstract: A control device for regulating the skimming flow of surface water from a swimming pool to a perimeter gutter includes a housing disposed in a gutter wall, at the normal level of water in the pool, which defines a flow passage from the pool to a lower gutter trough. A plate pivotally supported within a downwardly-sloped portion of the flow passage reduces flow through the housing in response to increasing levels of water in the trough. The plate closes the flow passage when the water in the trough exceeds a predetermined level to prevent flooding of the gutter and to prevent back flow of water from the gutter to the pool.
