  • Patent number: 10642189
    Abstract: A developer container unit to be mounted in an image forming apparatus that performs an image forming operation comprises a frame and a sealing unit. The frame is provided with a developer containing chamber containing developer and an opening for discharging the developer from the developer containing chamber. The sealing unit includes a shaft member rotatable about a rotational axis and a sealing portion attached to the shaft member and compressed by the shaft member and the frame to seal the opening. The sealing unit is rotatable to a close position at which the sealing portion seals the opening, a first open position at which the opening is open, and a second open position at which the opening is open. The sealing unit agitates the developer by executing a reciprocating motion between the first and second open positions during the image forming operation.

  • Patent number: 8960505
    Abstract: The device for the quantitatively regulated delivery of bulk product includes a supply tank for the bulk product and a slider element, which forms the boundary of an outlet gap on one side. The slider element comprises on its front end an elastic, U-shaped loop, the upper part of which is fixed in position, whereas a rear portion of the lower part of the loop is connected to a linear drive. The linear drive can be used both to adjust the width of the outlet gap by translational movement of the lower section of the loop and to produce a small-amplitude back-and-forth movement of the lower section of the loop. In this way, it is possible to release bulk product of various shapes and sizes reliably and without damage in a quantitatively regulated manner.

Each pump includes a reciprocably movable pump piston, which can “float” upwardly during a filling stroke, as each pump is filled with product delivered thereto under pressure. The pump pistons can move upwardly independently, until each reaches a predetermined position, corresponding to the quantity of product with which each container is to be filled. After all of the pistons reach their respective predetermined positions, valves of the pumps are simultaneously operated, and the pistons simultaneously stroked so that respective containers are filled with the flowable product.

The disposable nozzle assembly is further provided with a modified luerlock fitting having an internal hollow stem that mates with the tapered nozzle of a standard adhesive syringe in a manner which prevents the entrapment of an air bubble in the fluid path when an empty syringe is replaced.

  • Patent number: 5353959
    Abstract: A system and apparatus for producing seasoned food products where seasoning is performed at individual packaging lines. The product is conveyed from the preparation area to a packaging area in an unseasoned condition. Upon reaching the packaging lines, which are disposed in packaging departments in the packaging area, the product can be selectively seasoned independent of other packaging lines. After seasoning, the product is packaged and prepared for delivery. At each packaging line, a volumetric feeder includes a feed head that cooperates with a tumbler having helical flights to produce continuous controlled product portions. A seasoning dispenser is positionable within the tumbler and can be adjusted to dispense a given weight of seasoning at a given rate, based on the amount of product passing through the tumbler, to obtain consistent seasoning levels and coverage.

  • Patent number: 5341962
    Abstract: A feeder for discharging a load of material includes a hopper, a swing arm pivoting between raised and lowered positions in the hopper, and a ram mounted on the free end of the swing arm. The ram is moved by the swing arm back and forth on a curved floor in a trapezoidally shaped trough underneath the hopper to push material in the trough out of the hopper through a discharge outlet. A shutoff valve at the discharge outlet prevents backflow of discharged material into the trough.

  • Patent number: 5289954
    Abstract: A device for metered removal of flowable solid material comprises at least one delivery opening for the flowable solid material and an essentially horizontal intermediate storage floor for receiving the flowable solid material, arranged below said delivery opening. A collecting space for the flowable solid material is defined between the intermediate storage floor and the delivery opening. A lateral opening is positioned in the intermediate storage floor adjacent to the delivery opening. At least one removal rake with at least one blade is inserted into the collecting space and movable relative to the intermediate storage floor transverse to a delivery direction of the delivery opening for pushing the flowable solid material collected under the delivery opening into the lateral opening. A pivoting parallelogram-shaped rod arrangement with upper pivoting axes that are arranged in a common horizontal plane is provided for pivotably supporting the removal rake.

  • Patent number: 5020698
    Abstract: An ice-cream ejector for ejecting ice-cream filled with solid ingredients into an edible cone from a cup having a lower outlet. The cup is supported on a sliding shelf. A piston is pressed downwardly into the cup by a hand lever to press the ice cream out. The piston is quickly removable from the ejector for cleaning. A flexible resilient header extends across the underside of the piston and is removable for cleaning. A disposable piston cover of wax paper clings to the piston header as the piston retracts. The piston has an inclined wall portion guiding the piston into alignment with the cup during piston entry. Visibility of the outlet during cone-filling is increased by a notch in the shelf and by having the cup outlet below the shelf.

  • Patent number: 4972977
    Abstract: The present invention comprises a spray bottle in which the pressure resulting from the gripping force applied by the user is amplified and this increased pressure used in generating a spray such as an aerosol or fluid stream. In its preferred embodiment, the invention includes a high pressure chamber and a corresponding piston which is operative for driving fluid out of this chamber at high pressure through a spray nozzle and a low pressure chamber and a corresponding piston which is acted upon the hydraulic pressure within the bottle resulting from the gripping force. The low pressure chamber and piston are of larger size than the high pressure chamber and piston. The pistons are rigidly connected so that the force created by the pressure acting on the piston in the low pressure chamber is transmitted to the piston in the high pressure chamber where it is applied over a more limited area thereby generating greater hydraulic pressure for use in forming the spray.

  • Patent number: 4921133
    Abstract: A pump/dispenser, ratioing/mixer dispenser apparatus and a method and apparatus for precision vacuum degassed dispensing of work liquids are presented. The pump/dispenser is a positive displacement high precision piston/cylinder constant flush type with piston smaller than chamber. The piston is advanced along its stroke in tiny repeatable adjustably programmable steps, the infinitely adjustable precision ratioing programmable mixing being provided when two such pumps are used. The vacuum degassed work liquids dispensing system features the creation and maintenance of a positive absolute pressure on the work liquid(s) when exiting the degassing chamber(s) to the dispensing outlet(s) whether moved along the flow path through the precision dispensing pump(s) or other types of pump(s). Available softwear and adjustable programmable precision hardwear of the system may be provided by a widely available personal computer. Further degassing is provided by dispensing in a vacuum.
