The cutter elements are disposed perpendicular to the surface of the molten solder and partly submerged in the molten solder when the container is closed by the holder. The cutter elements are angularly offset from each other so that each end of the cutter elements lies on a spiral path. The cutter elements are rotated to repeatedly cut the dross into smaller pieces and force the dross as cut into the molten solder. This process removes oxides from the dross, and any free, reclaimed solder is returned to the molten solder.Type: GrantFiled: August 5, 2002Date of Patent: May 10, 2005Assignee: Senju Metal Industry Co., Ltd.Inventor: Shohei Mawatari

Publication number: 20040262436Abstract: A paper shredder cutting tool having multiple cutting edges constructed from a pair of cylindrical rotary cutters, which are each separately mounted on a hexagonal shaft, and a plurality of cutting blades are securely mounted on the shafts. A spacer is configured between each pair of adjacent cutting blades, thus partitioning the cutting blades therebetween, and thereby allowing the cutting blades to be assembled and mounted in an interleaving fashion on the two cylindrical rotary cutters. Moreover, each of the cutting blades is further constructed from a pair of blades. The present invention is characterized in having a plurality of cutting edges circumferentially arranged and minimally separated on each of the pair of blades, thereby forming a compact assembly of blade edges. The paper shredder cutting tool provides capability to feed around twenty sheets of paper or cardboard at one time, thereupon being rapidly shredded into small bits.Type: ApplicationFiled: January 2, 2004Publication date: December 30, 2004Inventor: Emily Lo

Publication number: 20040251356Abstract: An apparatus suitable for treating mineral material, particularly excavated earth, has two rollers that rotate in opposite directions, on which a plurality of elements is disposed, the elements serving to transport and reduce the material in case its particle size is too large. Elements that are designed to exert a notch effect onto particle sizes larger than a minimum size are provided for reducing brittle and large-particle components of the mineral material, in particular. The reduction by means of the notch effect has been proven to save energy and subject machines to low wear. The elements that produce the notch effect can also reduce wood (tree stumps).Type: ApplicationFiled: May 30, 2003Publication date: December 16, 2004Inventor: Hans Jurgen Schenk

Patent number: 6830207Abstract: A comminuting apparatus including a filtering screen member for collecting solids carried by an effluent stream. The filtering screen member has an upstream side and a downstream side. The comminutor apparatus further includes a twin shaft grinder for grinding solids contained in the effluent stream and for cleaning the filtering screen member of solids collected thereon. The comminutor apparatus also includes a mounting member in the form of frame-like structure for mounting the twin shaft grinder at a spaced apart distance from the upstream side of the filtering screen member. Additionally, the comminutor apparatus includes a moving device in the form of a drive motor for moving the twin shaft grinder past the upstream side of the filtering screen member such that the twin shaft grinder is continuously spaced from the filtering screen member during the movement of the twin shaft grinder.Type: GrantFiled: October 8, 2002Date of Patent: December 14, 2004Assignee: Franklin Miller, Inc.Inventors: William B. Galanty, Alexander Vilensky

Patent number: 6827300Abstract: An automatic start mechanism for a shredding apparatus is disclosed. The shredding apparatus includes a shredding mechanism for cutting the paper when the paper passes through a channel, a power source for outputting a motive power for the shredding mechanism, a trigger disposed at an entrance of the channel for arising a move when the paper passing through the channel to be against thereto, a delay unit for producing an against force driven by the power source, a lever connected between the trigger and the delay unit for moving in response to the trigger and the delay unit against, and a switch electrically connected to the power source and contacted to a first portion of the lever. The distance between the first portion of the lever and the trigger is smaller than a distance between the delay unit and the trigger.Type: GrantFiled: November 6, 2001Date of Patent: December 7, 2004Assignee: Primax Electronics, Ltd.Inventor: Pei-Yuan Lee

Patent number: 6820542Abstract: An apparatus 10 for compacting and baling leaves, grass clippings, sticks, pine straw and other debris on lawns, yards, or fields is provided. The apparatus 10 may have diagonal brushes 26 to gather debris for processing though a crusher 28, a conveyor belt 30 to transport the crushed debris, and a baler 32 to compact and bale the debris. The baler 32 may compact the debris by rotating the debris in a continuous band 52, into which baling material 72 may be inserted to bale the debris. Alternatively, the debris may be gathered and feed into a crusher 28 that deposits the crushed debris directly into the baler 32 for compacting and baling. Further still, the apparatus 10 may gather the debris with brushes 26 and feed it onto a conveyor mechanism 30 that then introduces it into a crusher 28. The crushed debris may then be feed into a baling mechanism 32 that compacts and bales the debris for easy removal and disposal.Type: GrantFiled: February 21, 2003Date of Patent: November 23, 2004Inventor: Bobby L.

Patent number: 6802465Abstract: A shredding machine comprises a housing, a shredding mechanism, a motor for operation of the shredding mechanism, a slot through which documentary material is fed for shredding by the mechanism, and an operating member movable from an operative position in which it extends across the slot, to an inoperative position retracted from the slot, in consequence of the feeding of the material into the slot, and returning, in the absence of the material in the slot, to its operative position under the action of a spring. A motor controller includes a microswitch having a plunger which is spring-urged into a projecting position, in which it is open circuit. The spring urges the operating member into its operative position. Thus, when material enters the slot, moving the operating member to its inoperative position, the plunger is depressed to start or permit operation of the shredding mechanism.Type: GrantFiled: June 10, 2002Date of Patent: October 12, 2004Assignee: Acco-Rextel Group Services LimitedInventors: Stuart Leslie Norcott, Paul Arthur Aries

Patent number: 6779747Abstract: A method for shredding a document which renders the information unintelligible and prevents or minimizes reassembly of the shredded document reconstruction of the information contained in the document. The ability to reassembly a shredded document is greatly reduced by shredding each page of the document into segments formed by cuts made in the blank space between characters or images on the page. A cut pattern in which all cuts are made in the blank spaces between characters or images produces pieces or shreds of the document which have no partial or portions of characters or marks which can be matched across adjacent pieces. A document is first scanned to provide an image which can be analyzed by a processor to determine a desired cut pattern for the document. The processor then generates a set of instructions to control and adjust the cutting blades in a shredding device to cut the document in the desired cut pattern.Type: GrantFiled: November 27, 2001Date of Patent: August 24, 2004Assignee: Hewlett-Packard Development Company, LP.Inventors: Brent J.

Publication number: 20040159729Abstract: A vehicle has a housing mounting within it a rotor assembly comprising parallel shafts having intermeshing cutter discs in axially spaced relation thereon. The discs have radial projections with first cutting edges extending axially to face in a rotatively leading direction. Cutter segments carried on the discs project radially outwardly to provide second cutting edges of lesser axial extent facing in the leading direction. A toothed member mechanism carries teeth which project into the axial spaces between the discs and provides axial surfaces for coacting with the first and second cutting edge.Type: ApplicationFiled: February 10, 2004Publication date: August 19, 2004Inventor: James L.
