  • Patent number: 8535125
    Abstract: A feed unit for filling a coin module with coins improved in such a way that a plurality of coin modules can be filled or loaded with just one feed unit. The coin feed unit is a coin drum which is rotatable inside a shell. A coin stock compartment is provided into which coins can be filled via a charge aperture. A dispensing compartment is provided inside the coin drum from which coins can be taken out via the discharge aperture. A passage is arranged in such a way that coins get from the stock compartment into the dispensing compartment as the coin drum rotates around a pivot pin.

  • Patent number: 7112120
    Abstract: A particle blast system includes a feeder assembly having a rotor with a plurality of pockets formed in the peripheral surface. The transport gas flowpath includes the pockets, such that substantially all transport gas flows through the pockets. The seal adjacent the peripheral surface is actuated by the transport gas pressure to urge its sealing surface against the rotor's peripheral surface. At start up, there is no substantial pressure between the seal and the rotor, reducing start up torque requirements.

  • Patent number: 6523723
    Abstract: Dosing feeder for a liquid that is in a container (6), comprising a dosing arm (2) that shows at least one dosing cup (2.1) that is open at the top. The dosing arm (2) is arranged in a dosing head (3) that in its turn shows a first duct (4.1) being in connection with the container (6). The dosing head (3) is movable or turnable in relation to the dosing arm (2) so that the dosing cup (2.1) alternately may be brought in connection with the first duct (4.1) for feed of liquid or may release the dosing cup (2.1) so that it gets accessible for the liquid. The dosing arm (2) may be cylinder-shaped, the dosing head (3) being turnable around the dosing arm (2). On filling with liquid into the dosing cup (2.1) the container (6) is above the dosing arm (2), the first duct (4.1) being connected with the dosing cup (2.1.). In position of rest the container (6) is under the dosing arm (2), the second duct (3.2) being connected with the dosing cup (2.1).

  • Patent number: 6382461
    Abstract: A method and device are disclosed for metering a predetermined amount of a particulate substance in a reliable and exact manner. The claimed invention avoids crushing or packing the material to be metered, and can be utilized with fine particulate substances with poor flow properties such as agglomerates as well as with coarser granulates. The substance to be metered is gravity-fed by a tumbling reservoir and inlet through an unbroken and uninterrupted inflow path which comprises two parts, one which is coaxial with the rotational axis, and a second which is inclined relative to the rotational axis. After passage through the inflow path, the substance enters the metering chamber which accurately and uniformly measures the desired quantity of substance, which then exits through the outflow path. The design of the device prevents inaccurate metering through overfilling or premature emptying of the metering chamber.

  • Patent number: 5285828
    Abstract: An apparatus for introducing filler material in a fluid carrier into a measuring chamber in rapid succession is described. The apparatus includes a delivery subsystem for introducing the filler material into the fluid carrier. The delivery subsystem provides the fluid carrier and filler material to a diverter subsystem which separates the stream into two separate streams. The two separate streams are directed into a rotating concentrator subsystem that separates the fluid carrier from the filler material and compresses the filler material. The filler material is further compressed and dewatered in a taper subsystem and drain subsystem. The filler material is then dispensed from the drain subsystem into a measuring chamber where it is cut by a knife plate that includes two blades with overlapping cuts. The apparatus is capable of introducing controlled weights or volumes of filler material into a measuring chamber at high speeds.

  • Patent number: 5259533
    Abstract: A dispenser for smoothly and reliably dispensing flowable or particulate matter such as fish food is provided, in which dynamic gravity of the matter itself is utilized to regulate dispensing of the same in an uncomplicated manner. The dispenser has a container adapted to be mounted upon a rotatable shaft and having a hollow interior with two openings therethrough for communicating with external surroundings. A partition is mounted within the container interior for dividing a portion of the container interior into a plurality of compartments. The partition extends between the openings to limit quantity of matter falling into one of the compartments as the container rotates. A duct is mounted to rotate with the container and communicates with one of these openings. As the container rotates, the partition regulates the quantity of matter falling into the dispensing compartment and directs matter not discharged from the dispensing compartment back into the other compartment.
