  • Patent number: 8651326
    Abstract: A singulating and counting device includes a bulk housing for storing a plurality of substantially identical articles, an exit channel, and in the exit channel, forwardly- and rearwardly-directed jet apertures, each of which is fluidly connected to a positive pressure source. A forwardly-directed jet generated by the positive pressure source through the forward jet aperture can accelerate singulated articles in the exit channel, thereby increasing the interval between individual articles and rendering them more easily and accurately counted. A rearwardly-directed jet generated by the positive pressure source through the rearwardly-directed jet aperture can cause articles in the exit channel to return to the housing.

  • Patent number: 8649898
    Abstract: Methods, apparatus, software and systems are disclosed for improved processing of mailpieces in order to reduce expensive manual steps. Shiny mail, i.e., mailpieces having glossy surfaces that sometimes interfere with printing of barcodes and or ID Tags may lead to rejects. In some embodiments, shiny mailpieces are identified, and at least one new (non-shiny) label is over-labeled in the POSTNET clear zone (108), the ID Tag zone (202), or both. In one embodiment, a specially-configured Reject Encoding Machine (REM) (1142) is employed to label or over-label a POSTNET clear zone (1110), resolve the destination address (1112) if possible, and print the barcode (1114) in a single operation. Thereafter, the mailpiece may be transferred from the REM into a downstream DBCS (1144), thereby re-introducing the mailpiece into the automated mail stream rather than being relegated to a manual stream.

  • Patent number: 8618432
    Abstract: A separation system includes an air separator that, in one embodiment, primarily receives Municipal Solid Waste (MSW) containing a mixture of relatively light MSW recyclable materials such as plastic, paper, cardboard, plastic containers, and/or metal containers and relatively heavy MSW such as textiles, food waste, yard debris, etc. The air separator blows the relatively light MSW recyclable materials up though a chamber and onto a first conveyor while the other relatively heavy MSW material drops down a chute onto a second conveyor. A separation screen receives the relatively light MSW recyclable materials from the air separator and separates the relatively flat fiber and plastic film materials from the other paper, plastic and metal containers. In another separation stage, an electrostatic emitter is positioned adjacent to a conveyor for applying an electrostatic charge to the fiber and plastic materials.

  • Patent number: 8584896
    Abstract: By either rotating a folded clip within a dispenser, or by folding the clip into a J-shape instead of a U-shape and then placing the clip into a dispenser, more sheets can be placed into the dispenser without causing an increase in dispensing problems. Alternatively, fewer dispensing problems result if the same number of sheets is placed into the dispenser. In one embodiment, the dispenser was an upright facial tissue carton and the clip was an interfolded stack of facial tissues.

  • Patent number: 8505738
    Abstract: A mobile material screening apparatus (100) for separating bulk particulate material into groups of particles of differing sizes comprises a support chassis (2), a horizontal screen box (3) housed within the support chassis (2) and an additional inclined pre-screening module (50) which is adapted to be demountably attached to the support chassis (2). The mobile screening apparatus (100) comprises five outputs. Foldable conveyors (7a, 8, 9, 910, 920) can be deployed outwardly from and stowed inwardly against the material screening apparatus. The provision of an inclined pre-screening module (50) provides relief to the horizontal screen box (3) by first removing the larger sized particles from the bulk material which can be returned to a crusher for recycling and serves also to increase the total number of grades of material separated by the screening apparatus.

  • Patent number: 8490252
    Abstract: In one embodiment, a system for removing a plastic wrap from a cylindrical module includes a conveyor transporting the cylindrical module toward a disperser with the cylindrical axis of the module parallel to the direction of conveyor movement. In another embodiment, the disperser is a travelling head disperser thereby providing relative movement between the modules and the disperser. The direction of the wrap around the module is determined and the cover is removed during rotation of the module, either by unwrapping the plastic or by slitting the plastic and then rotating the module. The equipment used to handle a cylindrical module is moved out of the path of movement of a conventional rectangular module so an installation can handle both rectangular and wrapped cylindrical modules.

  • Patent number: 8469198
    Abstract: A screen basket with replaceable profiled bars and method of making such screen basket are described herein. The screen basket includes profiled bars evenly spaced circumferentially to form a plurality of continuous slots that covers the whole basket length. The profiled bars are fixed in place by a backing structure, including support rings. In pulp and paper industry, this type of basket is mainly used for pulp screening and is commonly referred to as wedge wire basket. As opposed to conventional wedge wire baskets, in which the profiled bars are permanently joined to the rings, the present invention allows replacing the profiled bars when required and to fully re-use the main structural elements. This is achieved with an assembly that allows to insert the profiled bars, preferably consecutively sled into each aligned ring grooves in a vertical movement. The ring grooves are profiled such that there is sufficient clearance for sliding in the profiled bars.
