Patent number: 5480268Abstract: A rotary airlock feeder is connected to transfer particulate material between a storage bin and a pneumatic convey line. The pneumatic convey line includes a pressure reducing orifice plate which produces a pressure differential in the convey line between the upstream and downstream sides of the orifice plate. Air from the upstream side flows into respective specially designed end plates of the feeder and the pressure differential between opposite sides of the orifice assures a steady purge air flow circumferentially around a pair of rotary shrouds and into the feeder. This steady air flow prevents particulate material or debris from entering cavities between the shrouds and the end plates and between the rotary shrouds and the housing walls and thus prevents such material from reaching the seals, shaft area, and bearings of the feeder and protects the rotary shrouds from premature abrasive wear.Type: GrantFiled: May 9, 1995Date of Patent: January 2, 1996Assignee: Smoot CompanyInventor: David K.

Patent number: 5114053Abstract: A rotary feeder for granulated bulk material includes a housing with a rotor by which the bulk material is transported from the supply well to the discharge well via a plurality of compartments. Arranged at the inner wall of the housing is a pocket-like recess which is defined by a pre-stripping edge and by a V-shaped stripping edge extending from the pre-stripping edge. The pocket-like recess is V-shaped, with its tip pointing in rotational direction of the rotor. A deflector partly fills the recess to substantially free the tip of the recess from bulk material grains and includes a tip pointing opposite to the rotational direction of the rotor, sides converging in this tip and ending at a distance from the stripping edge by about the means grain diameter of the bulk material, and a base extending in the generated cylindrical surface defined by the radial end faces of the rotor.Type: GrantFiled: November 29, 1990Date of Patent: May 19, 1992Assignee: Waeschle Maschinenfabrik GmbHInventor: Walter Beirle

Patent number: 5072687Abstract: Several embodiments of apparatus for producing disposable absorbent personal articles are disclosed. According to one embodiment, apparatus is disclosed for depositing superabsorbent polymer powder on a portion of a fluff mat in a given concentration greater than zero and a second, different concentration of superabsorbent polymer powder on another portion of a fluff layer, so that there is a heavier concentration of super absorbent polymer in a target area than in areas adjacent the target area. Such apparatus has a dosing cylinder with a discontinuous outer cylindrical surface which has a pattern of first dosing depressions adjacent to a pattern of second dosing depressions. The dosing cylinder is rotated through a polymer powder hopper and powder received in the first and second depressions is sequentially discharged from the hopper and deposited on a fluff substrate in alternating areas of high powder concentration and low powder concentration.Type: GrantFiled: August 13, 1990Date of Patent: December 17, 1991Assignees: James G. Mitchell, Winalee G. MitchellInventors: Winalee G. Mitchell, James Mitchell, Michael Plotka, Gary Van Streader, Thomas Krassow

Patent number: 5065905Abstract: An apparatus for storing, transporting and dispensing hardware to workers at workstations on an assembly line. Specifically, this invention relates to a transportable rotatable dispensing apparatus. Thus, the apparatus can be loaded with supplies, hardware or articles, then transported to a multiplicity of workstations for workers to use in an assembly of a product. The apparatus has a base support and at least one storage unit mounted on top of the support. The storage unit is made up of a number of containers rotatably mounted on the support. Each container has a discharging device which is operator actuated. The discharged articles will drop into a chute that directs the articles to a receiving device mounted on the support. On top of the storage unit is a covering that has a loading device for allowing the containers to be loaded with articles.Type: GrantFiled: May 23, 1990Date of Patent: November 19, 1991Assignee: Xerox CorporationInventors: James A. Eddy, Alan N. Keller
