Patent number: 8083071Abstract: A classifier includes a central particle inlet, an inclined feed surface, and a classification surface. A plurality of particle feeding vanes are positioned above the feed surface, and the plurality of particle feeding vanes rotate above the feed surface. A plurality of classification vanes are positioned above the classification surface, and the plurality of classification vanes rotate above the classification surface. Particles enter the classifier through the inlet near an axis of rotation and flow radially outward on the feed surface to the classification surface.Type: GrantFiled: July 16, 2007Date of Patent: December 27, 2011Assignee: University of Florida Research Foundation, Inc.Inventors: Spyros A. Svoronos, Dongchul Lee, Hassan El-Sayed El-Shall

Patent number: 8002117Abstract: A method and apparatus for sorting a gas-driven stream of generally flat and light-weight articles of varying dimensions execute a, preferably optical, inspection and upon so finding a non-conforming article remove the latter from the stream. In particular, the inspection and the sorting are executed during a substantially straight movement of the articles. The removing is executed through gas driving in a direction substantially transverse to the straight movement. Advantageously, the inspection is preceded by orienting the articles through a centrifugal force that orients said articles against an inclined wall in a transition to the vertical movement. Also airflow means (83,84) can be used to confine the articles in a thin layer.Type: GrantFiled: October 19, 2005Date of Patent: August 23, 2011Assignee: Comas, S.p.A.Inventors: Thomas Marinus Antonius Van de Laak, Mario Martin, Robertus Cornelis Van Hoek

Patent number: 7975852Abstract: Centrifugal device (1) of the rotating bowl type for supplying preforms (2b), which are horizontally-laid and aligned, from preforms (2a) received in bulk, comprising a rotating transport ring (3) delimited by a lateral guide (12) and a central rotary disc (6) in the same direction as the ring and with an axis (8) inclined relative to that of the ring; a mobile member (15) mounted on the lateral guide occupies, as a result of the actuating means (18), an operational position in which the preforms (2c) are forced to leave the ring; detection means (19) upstream of the mobile member detect an undesirable preform (2c) on the ring and control actuating means for bringing the mobile member into its operational position for the ejection of the undesirable preform.Type: GrantFiled: October 23, 2007Date of Patent: July 12, 2011Assignee: Sidel ParticipationsInventors: Alain Charpentier, Daniel Diesnis

Patent number: 7413084Abstract: The present invention is directed to a system and method for continuously or substantially continuously separating particulate matter based on particle size and/or density of the matter. The system includes a separation chamber having a bottom portion disposed within a cavity of a rotatable bowl having fluid therein, preferably water. The internal cavity of the separation chamber is maintained under negative pressure such that fluid is drawn through the separation chamber at a predetermined velocity to separate the solids. Larger, dewatered and/or denser solids are directed to the cavity of the rotatable bowl and can be removed by rotation of the bowl while the smaller and/or less dense solids and fluid travel up through the separation chamber.Type: GrantFiled: October 19, 2005Date of Patent: August 19, 2008Inventor: Paul C. Wegner

Patent number: 7384503Abstract: A method and system for determining trace oversize contaminant particles in a paper-making pulp employs a screen assembly having a screen housing with a screen mounted therein, and ports for introduction of aqueous pulp and rinsing and flushing fluids, and for withdrawal of screened aqueous pulp, the screen housing has no port designated for the sole purpose of removing accumulated contaminant particles from the screen housing; instead the port employed for introduction of aqueous pulp and which may also be employed for introduction of rinsing fluid to the housing, is employed as the flushing port for removal of contaminant particles.Type: GrantFiled: June 1, 2004Date of Patent: June 10, 2008Assignee: FPInnovationsInventors: John David Hoffmann, James Allen Olson

Publication number: 20040026301Abstract: The invention relates to the field of machines for directing and aligning plastic containers and particularly relates to an universal device for automatically adjusting vertically directing and aligning means in dependence on said containers size. The orienting means are formed by a plurality of cradles (5) and the aligning means are formed by a corresponding plurality of discharge channels (6), both means are provided with movable parts (10) and (35) respectively adjustable in dependence on plastic containers size. The device provides at least one control member (7) located on the machine outer stationary cylindrical wall (3) and adapted to engage movable parts (10) and (35) of cradles and discharge channels respectively while the inner hopper holding bulk plastic containers rotates.Type: ApplicationFiled: May 1, 2003Publication date: February 12, 2004Inventor: Mario Lanfranchi

Patent number: 5135113Abstract: A device for sorting tablets by capacitive measurement, including a disk rotating between capacitor plates, a tablet fielding device for sequentially metering a series of tablets onto the disk, an arcuate guide assembly for guiding the tablets along a guide path as the disk rotates, and a deflector assembly for deflecting the tablets along one of the possible paths, as a consequence of the capacitance measurement.Type: GrantFiled: April 1, 1991Date of Patent: August 4, 1992Assignee: Modern Controls, Inc.Inventors: Daniel W. Mayer, Steven W. Broders

Patent number: 4126226Abstract: The separator comprises a housing with a charging apparatus arranged above an apparatus for delivering and preparing the ore in a layer one grain thick. The apparatus for delivering is made as a bowl provided with a drive for rotation. Enveloping the bowl is a vertical partition dividing the interior of the housing into annular compartments for receiving the products of separation. Disposed above the bowl is a horizontal light-insulating partition on which X-ray tubes, photocells and air ejectors are mounted. The horizontal partition is formed with an opening to receive the charging apparatus and with slots for the passage of X-ray radiation, X-ray luminescence and air pulses.Type: GrantFiled: December 28, 1976Date of Patent: November 21, 1978Inventors: Mark B.
