Patent number: 5460727Abstract: A novel waste water clarifier system for use in long settling basins utilizes a novel high strength-to-low mass ratio chain loop system of non-metallic material in a low friction drive and support system in which roller contact is facilitated at all points of wear. The chain links are formed of multiple layers of fiber reinforced resin tapes laminated together within a desired cross-sectional area and incorporating interior bushings for link interconnections into a chain loop. All rotary and linear wear mechanisms are low friction, rolling contact devices, incorporated in or arranged with the necessary flights and shafts. Both long life and protection against equipment malfunction are enhanced by the low mass, low drag components together with the high safety margins in the chain loops.Type: GrantFiled: June 27, 1994Date of Patent: October 24, 1995Assignee: Oritex CorporationInventor: Arthur L. Davis

Patent number: 5431272Abstract: To move or remove a workpiece from a worktable, as for example a finished workpiece from a work station, an elongate conveyer member, once it has been positioned so that at least a portion thereof is superposed over the finished workpiece, is lowered to contact at least one portion of the finished workpiece. Upon contact, the conveyer member is activated to convey the workpiece away from the work station, and if desired, automatically convey the workpiece to a storage bin or pallet.Type: GrantFiled: January 21, 1993Date of Patent: July 11, 1995Assignee: Finn-Power International, Inc.Inventor: Mikko Lindstrom

Patent number: 5317941Abstract: An overwidth slitting method slits a metal strip into two lengthwise pieces while trimming the side edges from the strip. The metal strip is placed on parallel spaced apart conveyors adjacent a slitter for conveying the strip to the slitter. The conveyors are raised above a plurality of vacuum cups which are disposed between the conveyors and are spaced along the length of the strip. The raised metal strip is aligned with respect to the slitter and the raised conveyors are lowered to a position where the bottom surface of the aligned strip engages the vacuum cups between the conveyors. A vacuum is applied to the vacuum cups for holding the strip in alignment relative to the slitter and then the metal strip is advanced on the conveyors into the slitter while sequentially releasing the vacuum from each vacuum cup engaged with the bottom surface of the metal strip as it advances. The advancing metal strip is simultaneously slit into two lengthwise pieces while the side edges are trimmed therefrom.Type: GrantFiled: March 31, 1993Date of Patent: June 7, 1994Assignee: Westinghouse Electric Corp.Inventors: Gary J. Williams, Todd E. Stokes, Joseph A. Leigh, James L. Maag

Patent number: 5186596Abstract: A longitudinal extensible platform comprises a plurality of framed sections hingedly joined together. Each framed section comprises a first set of ground engaging rollers and a second set of load engaging rollers extending transversely of the framed section. A drive is mounted below the surface of the loading dock for driving an endless chain. The extensible platform is drivingly engaged to the endless chain and adapted for longitudinal movement therealong. The extensible platform has a platen at a forward end hingedly engaging the first framed section. The extensible platform is provided with a driven pusher assembly mounted thereon. The pusher assembly extending upwardly for abutting with the load resting on the extensible platform.Type: GrantFiled: October 4, 1991Date of Patent: February 16, 1993Inventors: Paul Boucher, Mario Boucher, John Ford, Gregg Stephenson

Patent number: 5180049Abstract: A metal sheet is supported and transported in relation to a punching and/or shearing station, by supporting the sheet on upwardly projecting flexible bristles, the tips of which define a supporting plane. The bristles have their bases embedded in strips that are removably jammed in grooves defined in a stationary base structure. A conveyor, arranged beside the supporting plane includes a driven, endless belt. The belt has transversally extending bristle bars mounted to it so that, in its carrying run, its upwardly projecting bristles have tips which are effectively coplanar with the stationary supporting surface.Type: GrantFiled: October 21, 1991Date of Patent: January 19, 1993Assignee: Salvagnini S.p.A.Inventor: Guido Salvagnini

Patent number: 5147047Abstract: A method and apparatus for inspecting cylindrically configured pellets for surface defects is disclosed. At least one axially extending linear portion of the peripheral surface of the pellet is optically sensed. A set of discrete digital values representative of the optically sensed linear portion of the pellet surface is generated and the set of digital values is compared to a predetermined standard. Groups of digital values representative of adjacent locations on the surface of the pellet having values greater or less than the predetermined standard are identified. The area of adjacent digital values having a value above the standard, and the area of adjacent digital values having a value below the standard are calculated and compared to a predetermined area. The pellet is rejected when the calculated area exceeds a predetermined area.Type: GrantFiled: January 14, 1991Date of Patent: September 15, 1992Assignee: Westinghouse Electric Corp.Inventors: Hassan J. Ahmed, John M. Beatty, Ralph W. Kugler

Patent number: 5131241Abstract: A method and an automatic plate freezer for freezing food products in boxes or trays, or in containers of low mechanical strength and therefore being deformable, or of nonparallelepiped shape.Such boxes or containers are frozen in a plate freezer within which a moisture-free atmosphere is maintained together with dehumidified cold air circulation. Jets of dehumidified cold air are fed under the base of the containers in the container loading/discharge station to form an air cushion between the upper surface of the plate at rest in the station and the base of the containers, which can thus be easily thrust forward directly by other successively loaded containers insofar as the resistance to the movement of the containers along the plate is very low.Type: GrantFiled: April 8, 1991Date of Patent: July 21, 1992Assignee: Stal Samifi S.p.A.Inventor: Guido Battistella
