  • Patent number: 10443597
    Abstract: A gear pump includes a drive gear with drive gear teeth and a driven gear with driven gear teeth. The drive gear is rotatably disposed about a drive gear axis. The driven gear is rotatably disposed about a driven gear axis and is intermeshed with the drive gear such that a plurality of driven gear teeth are in sliding contact with a plurality of the driven gear teeth. One or more of the drive gear teeth or the driven gear teeth define within the tooth interior a cavity. The cavity is in fluid communication through an orifice with an inter-tooth volume defined between the contacting drive gear teeth and driven gear teeth such that fluid flows through the orifice to reduce cavitation within fluid confined within the inter-tooth volume.

  • Patent number: 7287673
    Abstract: The present invention refers to a refill container unit for an automatic dosing device. The purpose of the automatic dosing device is to control the dosing of stored material kept inside the container unit. The object of the container unit according to the invention is to achieve an agitating and transporting, cleanable and switchable storing arrangement for the automatic dosing unit. The refill container unit therefore comprises an agitating part (14) enclosed by a receptacle (1). The agitating part (14) agitates and feeds the material. Shaped as a pot containing the material, the agitating part (14) can also be lifted out of the receptacle (1) and cleaned or replaced by another pot. As an alternative the whole refill container unit can be replaced.

  • Patent number: 7275664
    Abstract: Disclosed is a self-aligning auger drive assembly. The assembly includes a hopper with an auger supported therein. A shaft is connected to and extends from the auger externally from the hopper. A coupling is associated with the shaft and is operatively associated with a biasing device which creates an engaging force to promote engagement of the coupling with a motor assembly driver. A portion of the coupling defines a recess which receives at least a portion of the driver as the driver is rotated.

  • Patent number: 7219517
    Abstract: A washing machine having a detergent supply device which is easily installed in a cabinet of the washing machine, and is not exposed to the outside of the cabinet. The detergent supply device includes a detergent container and a handle, and is seated in a reception chamber defined at an upper portion of the cabinet. Locking slots are formed on side mounting parts of the handle, and locking projections are provided on opposite sidewalls of the reception chamber, so as to have the locking projections be inserted into the locking slots where the handle is downwardly rotated. A cover is hinged to an upper portion of the reception chamber so as not to expose the detergent supply device to the outside. At least one hook is provided on a front end of the cover, and at least one hook hole is formed on a front portion of the reception chamber to engage with the hook, so as to have the cover openably cover the upper portion of the reception chamber.

  • Patent number: 7188754
    Abstract: The present invention refers to an automatic dosing device. The purpose of the device is to store and dose material, kept inside a container part, and to make it possible for an operator to refill the container with material. The automatic dosing device therefore comprises a refilling container (1), a dosing screw (5), a control system, a driving motor and a guiding mechanism (14–16, 19). The container (1) stores the material, the screw (5) doses it out of the container (1), the system controls the dosing and the mechanism (14–16, 19) guides the container between an inner position where the device can dose material and an outer position where an operator is allowed to refill it with material. The automatic dosing device could preferably be used with a laundry washing machine but there is also possibilities to use the automatic dosing device in another machine that requires an easy handle automatic dosing device.

  • Patent number: 6945287
    Abstract: A backflow blocker prevents backflow of gas to a lower pressure first stage of a system for processing particles from a downstream higher pressure second stage of the system. The blocker comprises an upright duct connecting the first stage to the second stage. The duct is at least partly filled with a column of particles passing from the first stage to the second stage. By properly selecting the duct dimensions and by controlling the flow rate of particles into and from the duct, the velocity of downwardly moving particles in the duct can be made to exceed the velocity at which the gasses flow through the particles in the duct. This prevents gasses from flowing from the lower pressure downstream stage to the higher pressure upstream stage.

  • Patent number: 6932245
    Abstract: A dispensing canister and method for reducing dose fluctuation and improving evacuation in the dispensing of a pulverulent material such as beverage-forming or food-forming powder. The dispensing canister has a reservoir having an inlet and an outlet and defining a volume for retaining the pulverulent material therein, a dosing member operatively associated with the reservoir outlet for receiving and dispensing the pulverulent material; and an agitator wheel located in the reservoir and arranged to periodically rotate to assist in dislodging pulverulent material in the reservoir so that it can move to the dosing member. The agitator wheel preferably includes agitating members for transversing a significant portion of the volume of the reservoir to contact and dislodge pulverulent material therein.

  • Patent number: 6688496
    Abstract: The invention relates to a dosing device containing a supply container (8), a dosing container (30) and a discharge device (12). A separate vertical stirring section (22, 22A) is provided in each container, namely the supply container (8) and the dosing container (30). The vertical stirring section 22A located in the supply container (8) is provided with a drive unit (1) which is also used to drive the lower stirrring section (22) of the dosing container (30). The dosing container (30) can be removed horizontally, sideways. The two stirring sections (22) and (22A) have coupling elements (16, 25) with which they are detachably or releasably interconnected. A coupling arm (25) is provided to this purpose with driving pins (16) which engage in the rotating area of the driven upper stirring section (22A) so that the two stirring sections can be coupled and one stirring section can drive the other stirring section.

  • Patent number: 6571990
    Abstract: A method and apparatus for adjustably directing granular material through a container. The apparatus includes a converging transition portion defining an input opening that converges to an output opening having a first transverse opening dimension (x1). The apparatus further includes an elongated chimney portion coupled to the converging transition portion and having a second transverse opening dimension (x2), where the first transverse opening dimension (x1) is smaller than the second transverse opening dimension (x2). This configuration reduces the outlet pressure created in the converging transition portion as the granular material passes through the container to minimize bridging of the granular material within the container.

    Abstract: A bulk-solid metering system has a support structure. A feed hopper is mounted with respect to the structure and has an upper edge. In the improvement, the structure includes an upper member and the upper edge is below such upper member. The structure defines a lateral opening sized and shaped to permit the feed hopper to be withdrawn laterally through the opening. The feed hopper includes a spout extending therefrom. In a highly preferred embodiment, the lateral opening is positioned to permit withdrawal of the feed hopper in a direction away from the spout. The feed hopper is configured to promote very good mass flow as well as to permit agitation in that, in one embodiment, it has a body made of flexible material. There is a hopper upper flange and the spout is spaced below such flange. The body has a first cross-sectional shape, e.g., circular, adjacent to the upper flange and has a second cross-sectional shape, e.g., ellipse-like, intermediate the upper flange and the spout.
