Patent number: 6669410Abstract: A high pressure transfer device has a rotor mounted in a housing for rotation with respect to inlet and outlet ports and having through going pockets. The pockets have interior surface configurations substantially devoid of nooks, crannies, and related flow restrictions. This can be accomplished by providing inserts in the pockets, or by constructing the pockets so that there are substantially smooth interior wall tubes extending from one end of the rotor and the other and cooperating with an inlet and an outlet at the same time. Using the high pressure transfer device to feed wood chips or the like in a slurry using a high pressure transfer pump can result in flow through the rotor pockets that is more uniform by at least 5% compared to in conventional high pressure transfer devices.Type: GrantFiled: February 3, 2003Date of Patent: December 30, 2003Assignee: Andritz Inc.Inventor: J. Robert Prough

Patent number: 6345936Abstract: An ejector for providing motive gas for conveying particulate solids from a solids supply vessel through a conveying pipeline includes a gas introduction stage and a solids introduction stage. The gas introduction stage includes a fluids mixing chamber having a principal inlet port for connecting to a source of high-pressure compressed gas, an outlet port connected to the solids introduction stage, and a secondary inlet port that is open to the atmosphere or other low-pressure gas source. The solids introduction stage includes a fluids/solids mixing chamber having an, inlet port connected to the gas introduction stage, an outlet port for connecting to a pipeline, and a material receiving port for connecting to a vessel outlet. As the compressed gas enters the gas introduction stage, the high velocity gas induces atmospheric air or other low-pressure gas from the secondary inlet port, thus increasing the mass flow into the solids introduction stage.Type: GrantFiled: January 25, 1999Date of Patent: February 12, 2002Assignee: The Young Industries, Inc.Inventor: John W.

Patent number: 6216876Abstract: The invention is an adjustable portable vacuum assisted device for collecting dense matter, such as nuts, while separating and ingesting less dense matter in the same original environment as the nuts, such as leaves or other lawn refuse. The source of vacuum may be the inlet side of a lawn blower. In the invention, ambient forces, such as gravity and turbulence disengage dense solids in a gaseous stream from less dense matter in the gaseous stream induced by the vacuum means without operational malfunction caused by clogging or jamming of the device. Disengaged dense matter is collected within a collection chamber while less dense matter is ingested through and discharged by the vacuum means.Type: GrantFiled: August 20, 1998Date of Patent: April 17, 2001Inventor: Henry M. Quillian, III

Patent number: 6203250Abstract: An apparatus for feeding semiconductor chips has a structural body having grooves which serve respectively as parallel feed paths for semiconductor chips, the feed paths corresponding to respective quality levels of the semiconductor chips, the structural body being made of partially stabilized zirconia. A stopper mechanism for temporarily stopping semiconductor chips fed along the feed paths comprises piezoelectric bodies disposed in the feed paths in front of terminal walls of the feed paths. A counter mechanism for counting semiconductor chips fed along the feed paths have electrodes disposed in the feed paths near the terminal walls. The apparatus serves as a feed system for floating articles with ejected air and feeding the floated articles, and lends itself to being automatized.Type: GrantFiled: December 15, 1998Date of Patent: March 20, 2001Assignee: NGK Insulators, Ltd.Inventors: Yukihisa Takeuchi, Hiroyuki Tsuji, Takao Ohnishi

Patent number: 6193074Abstract: A conveyor for the sorting of mixed cargo, especially of packages, small packets, containers and pieces of luggage, includes Carts (5) coupled to each other and each movable along Running Rails (9) and having an Undercarriage (6). Support Elements (12) are arranged on the Undercarriage (6) and spaced apart from each other in the Direction of Motion (F). A Tilting Axle (4) is mounted on the Support Elements (12) and runs in the Direction of Motion (F) for supporting through a Lever (13) a Carrying Tray (3) that can be swiveled out of a transport position that is generally horizontal into a tilted position for the lateral delivery of Mixed Cargo (2) into a predetermined target station. A Sliding Element (16) is connected in a movable fashion with the end of the Lever (13) turned away from the Carrying Tray (3) and guided between and at the Support Elements (12) crosswise to the Direction of Motion (F), for carrying out the tilting movement.Type: GrantFiled: November 4, 1998Date of Patent: February 27, 2001Assignee: Mannesmann AGInventors: Ingolf Baum, Heinrich Droste, Holger Humburg

Patent number: 6109426Abstract: A bottle conveyor to maintain positive control over the orientation of bottles includes guides above and below a collar around the neck of the bottles on either side of the neck. The guides may be endless belts and/or fixed guides. Endless belts may also advance the bottles and may be driven at the same or different speeds to prevent or induce rotation in the bottles as desired. The distance between guides may be adjusted to adapt the conveying system to bottles having various collar thicknesses and neck diameters and to regulate the amount of allowable swing.Type: GrantFiled: November 13, 1996Date of Patent: August 29, 2000Assignee: Simplimatic Engineering CompanyInventor: Carroll B. Messer, III

Patent number: 6095338Abstract: A sieve screen utilizes a frame to support a plurality of profiled screen wires. These screen wires are arranged on the frame in a symmetrical manner about a center line which is transverse or normal to the direction of flow of material to be separated. The sieve screen can be inverted and rotated to extend its life after the profile screen wires initially situated above the transverse central line have lost their separatory effectiveness.Type: GrantFiled: May 20, 1998Date of Patent: August 1, 2000Assignee: Conn-Weld Industries, Inc.Inventors: Michael S. Connolly, Stephen R. Andretich

Patent number: 6003679Abstract: A sieving device includes a sieve having a base, a drum and a main rim. A screen assembly having a mesh screen and a screen frame extending around a periphery of the mesh screen is resiliently mounted within the main rim. A low frequency vibrational drive vibrates the sieve at low frequencies. An ultrasonic vibrational probe rests on the screen frame free of rigid attachment thereto and vibrates the mesh screen around a periphery thereof. The ultrasonic vibrational drive includes an ultrasonic processor which drives the ultrasonic probe. A probe tip of the probe extends through a side wall of the main rim and rests on a top surface of the screen frame vibrating the screen from the periphery of the screen inwardly to sieve a particulate material. An alternative embodiment has a tab which extends outwardly from the screen frame. The probe tip extends through the sidewall of the main rim and through a sidewall of the drum to abut the tab.Type: GrantFiled: May 7, 1997Date of Patent: December 21, 1999Inventors: Victor William Maroscher, Dennis Keith Ulrich, Frederick T.

Patent number: 5967330Abstract: The present invention relates to an improved method of removing and transporting empty, recyclable, aluminum and plastic beverage containers returned to redemption centers without requiring the redemption centers to sort the containers by distributor and then separate the containers into like materials for removal. The present invention also illuminates the burden imposed on the distributors from having to pick up the containers from the redemption centers, then shred or bale the materials, and then sell the materials to recyclers. The invention comprises the steps of collecting and depositing the aluminum and plastic containers into a single holding bin at the redemption center's facilities. Using a blower such as a centrifugal fan and chute to blow the contents of the holding bin into a transporter such as a semi-trailer or compactor. Transporting the transporter to a separating facility which automatically separates the aluminum and plastic containers into like materials.Type: GrantFiled: October 26, 1998Date of Patent: October 19, 1999Assignee: MidAmerica Recycling CompanyInventor: Jeffrey J.
