The splash surface is sized to substantially correspond with the circular path defined by the rotatable spray head whereby pressurized fluid passing through the belt is continuously redirected against the opposing side of the conveyor belt upon contact with the splash surface.Type: GrantFiled: June 27, 2003Date of Patent: May 16, 2006Assignee: Tarpaulin.Com, Inc.Inventor: Kevin V. Gray

Patent number: 6983510Abstract: Systems and methods for cleaning belts used to move fiber optics are disclosed. In general, the system includes wheels that can be arranged to receive a fiber optic belt. The belt can be arranged between a contact plate and a brush. Movement is provided to both the belt and brush and a frictional force is created between the surface of the belt to be cleaned and the brush. This contact and friction cleans the residue from the belt.Type: GrantFiled: September 20, 2002Date of Patent: January 10, 2006Inventor: Herbert Ray Hudgins

Patent number: 6971503Abstract: A conveyor belt cleaning apparatus includes a debris-removal stage, a washing stage, a rinsing stage, and a water removal stage all positioned in a multi-chambered drawer with each of the four stages is provided with an isolated bin within that drawer. The various stages within the conveyor belt cleaning apparatus provide for the continuous or on-demand cleaning of a conveyor belt in order to remove any debris and fluids from the belt thereby providing a clean belt surface for use by the grocery store customer. The device may be installed as a new element in a check stand, or it may be retrofitted to an existing check stand.Type: GrantFiled: November 26, 2003Date of Patent: December 6, 2005Inventor: Cynthia Thompson

Patent number: 6945383Abstract: A solvent dispensing mechanism is fluidically coupled to create a substantially uniform wet region of a belt surface scrubber. Mechanisms for selectively engaging and disengaging the scrubber ensure free belt travel during flexible material transport and the cleaning of both surfaces during cleaning cycles. The system includes consumable piece-part elements for refurbishing and remanufacturing.Type: GrantFiled: January 9, 2003Date of Patent: September 20, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventor: Le Pham

Patent number: 6938754Abstract: A self cleaning conveyor roller for supporting a conveyor media carrying contaminant materials. The conveyor roller consists of a drum defining a support surface, having a generally cylindrical shape, and being adapted to be supported for rotation, for supporting a conveyor media. The conveyor roller has a plurality of abutments on the support surface, raised above the support surface, and defining a series of spaced apart conveyor media support ridges lying on a circular configuration, concentric with the drum. The abutments are arranged in generally chevron shapes, around the drum. During rotation of the conveyor roller the abutments cause any debris or contaminants between the roller and the conveyor media to be guided out of the conveyor system. Also disclosed is a method of cleaning a conveyor roller.Type: GrantFiled: February 26, 2003Date of Patent: September 6, 2005Assignee: Van der Graaf Inc.Inventor: Alexander D Kanaris

Patent number: 6851545Abstract: The conveyor system includes a conveyor bed mounted on a frame and an endless conveyor belt moving between upper and lower flight pads relative to the conveyor bed. A separate drive unit for the belts includes an enclosed housing having an opening therein through which the conveyor bed passes. The housing contains a belt drive mechanism including a plurality of belt pulleys engaged with the belt for receiving the conveyor belt from one of the upper and lower flight pads, applying motor power to the belt, and returning it to the other of the flight pads. The enclosure also includes a UV irradiation light source interposed in the path of travel of the belt through the housing for disinfecting the surfaces of the belt and the interior of the housing as the belt passes therethrough.Type: GrantFiled: March 23, 2004Date of Patent: February 8, 2005Assignee: Caddy CorporationInventor: Thomas Eric Carter

Patent number: 6695121Abstract: A dustproof linear actuator has: a housing with a slit extending axially; a linear guide device disposed in the housing; a carriage mounted in the housing and axially movable along the slit by the linear guide device, the carriage including a workpiece mounting table protruding from the housing through the slit; a linear drive device disposed in the housing for moving the carriage axially; a pair of pulleys disposed in an axial end of the housing; and a sealing band mounted around the pulleys within the housing movably for closing the slit, the sealing band including first and second ends which are fastened to first and second ends of the carriage, respectively, to form a circulative loop. Further, the dustproof linear actuator has an air venting device for venting air existing in the housing close to the axial end toward an outside of the housing so that the dustproof linear actuator can remarkably prevents the dust particles from leaking out of the housing by reducing the pressure inside the actuator.Type: GrantFiled: February 26, 2003Date of Patent: February 24, 2004Assignee: NSK Ltd.Inventors: Sosuke Kawashima, Nobuhito Saji
