Meshing Conveyer Trap Or Groove And Ejector Rotor Patents (Class 222/220)
  • Patent number: 8252117
    Abstract: A feed system and related process are configured to continuously feed measured doses of source material to a vapor deposition apparatus wherein the source material is sublimated and deposited as a thin film on a substrate. The system includes a bulk material hopper, and an upper dose cup disposed to receive source material from the hopper. A lower dose cup is disposed in a vacuum lock chamber to receive a measured dose of source material from the upper dose cup. A transfer mechanism is disposed below the vacuum lock chamber to receive the measured dose of source material from the lower dose cup and to transfer the source material to a downstream deposition head while isolating the deposition conditions and sublimated source material within the deposition head.

  • Publication number: 20030234261
    Abstract: The invention relates to a dispensing canister that improves dosing consistency and powder evacuation, particularly when dry powdered beverage-forming or food-forming material having poor intrinsic flowing properties are to be dispensed. The canister includes a reservoir having two terminal walls and two side walls, a rotatable volumetric dosing device longitudinally extending in the reservoir, and a main agitating wheel arranged to gear on the rotatable volumetric dosing device to rotate in the reservoir upon actuation of the rotatable dosing device. The secondary agitating wheel is arranged to gear on the main agitating wheel and the two wheels are vertically offset so that the main wheel is arranged to act in a downward rotation closer to a first terminal wall whereas the secondary wheel is arranged to act in a downward rotation closer to the second terminal wall.

  • Patent number: 6000446
    Abstract: A method including: a particulate material source and receiver, and wherein the source contains a discharge feature; moving material in the source in the direction of a member located at least partially within the source, the member defining an adjustable restriction therein such that the particulate material clogs within the restriction; mechanically agitating the particulate material in the source, at least adjacent to the restriction to thereby unclog the particulate material within the adjustable restriction; and dispensing particulate material through the adjustable restriction, through the discharge feature, and into the receiver.

  • Patent number: 5947169
    Abstract: A method for filling a powder container is provided. The method includes the steps of placing a first powder container to be filled in filling relationship to a discharge feature in the vessel, directing the powder in the vessel toward a member located at least partially within the vessel, the member defining a restriction therein such that the powder clogs within the restriction, mechanically exciting the powder at least adjacent the restriction to improve the flow properties of the powder so as to unclog the powder within the restriction, dispensing powder through the restriction, through the discharge feature and into the first container, stopping the mechanical excitation of the powder so as to clog the restriction with the powder, removing the first container from the vessel, and placing a second container to be filled in filling relationship to the vessel.

  • Patent number: 5007564
    Abstract: A dosing or metering feeding apparatus for precisely feeding a stream of powdered or fine grained loose bulk material includes a cylindrical container (1) for storing the loose material (3). A rotating turntable (4) essentially closing the bottom of the container (1). A discharge groove (6) is located in the turntable around the circumference of the turntable (4), whereby the discharge groove (6) opens radially outwardly. A stripper is arranged to reach into the discharge groove (6) for stripping the dosed material (3) from the discharge groove (6) and for discharging the dosed or metered material. This arrangement provides a clearly defined discharge rate of the loose material. The discharge rate may be simply adjusted to different desired feed rates by varying the rotational speed of the turntable (4). A high dosing or metering precision is achieved.
