Patent number: 6708412Abstract: A bench plane jointer fence having a fence body secured to the side of any conventional ferromagnetic bench plane by two rare earth magnets mounted in the fence body and by the cooperation between a fence registration surface that bears against the sole of the plane and a repositionable stop screw. The fence is usable to facilitate planing of a workpiece edge square to an adjacent workpiece reference surface and may utilize a one-piece fence body. Planing of a workpiece edge at angles other than square to an adjacent workpiece reference surface is possible by pivoting a lower portion of the fence relative to an upper portion or, in the case of a one-piece fence body, by attachment of an auxiliary fence having a wedge-shaped cross section.Type: GrantFiled: August 22, 2001Date of Patent: March 23, 2004Assignee: Lee Valley Tools, Ltd.Inventors: Terry Ross Saunders, Leonard G.

Patent number: 6677256Abstract: Absorbent structures that form superabsorbent polymers in situ. The structures include an absorbent material and a fibrous material containing an activating agent. The fibrous material releases the activating agent upon stimulation with an activator, which causes the polymer to become a superabsorbent polymer. The absorbent component is desirably a water-swellable, water-insoluble polymer. The absorbent structures form a superabsorbent composition in situ. Methods of making the activating agent containing fibrous material are provided.Type: GrantFiled: December 28, 1999Date of Patent: January 13, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Tong Sun, Werner Lonsky, Yong Li, Jian Qin, Xiaomin Zhang, Jacek Dutkiewicz

Patent number: 6634585Abstract: A highly mobile, compact creel (20) that utilizes frames (22) for holding yarn packages (30) (or bobbins) for feeding yarn (33) to a tufting machine (58). Each frame (22) includes holders (60) affixed to the frame (22) for holding yarn packages (30) facing front (24) and back (26), a header (32) attachable to the frame (22) for directing yarn (33) from the yarn packages (30) to the tufting machine (58), and anti-static flexible tubing (50) for leading yarn (33) from the holders (60) to the header (32). The header (32) provides for aligning all the yarn ends in the same plane to join them to ends already threaded into the tufting machine (58).Type: GrantFiled: July 23, 2001Date of Patent: October 21, 2003Assignee: Interface, Inc.Inventor: William O. Ingram, III

Patent number: 6622443Abstract: A plastic trim strip for use with high pressure plastic laminate (HPL) modules or other decorative modules used on access flooring. The strip is extruded polyvinyl chloride or other polymeric or other material such as decorative metals such as brass or aluminum. The cross sectional shape of the strip is generally rectangular with a rectangular tab that: (1) protrudes from one of the narrow edges of the rectangle, (2) is thinner than the height of the strip and (3) has one surface flush with the bottom of the strip. A portion of the edge of the HPL or other floor covering with which the strip is used, and having the same shape as the tab, is router or otherwise removed from the floor covering. The protruding tab of the trim strip is then “captured” within this rabbet with or without adhesive, thereby securely engaging the trim strip when the floor covering is installed on or bonded to the access flooring structure.Type: GrantFiled: April 11, 2000Date of Patent: September 23, 2003Assignee: Interface, Inc.Inventors: Frank J. Votolato, Victor A. Sainato, Sr.

Patent number: 6607016Abstract: A jig having a guide block and a repositionable clamp for use with a saw for hand cutting tails and pins on the ends of boards to form a dovetail joint. The guide block has four planar sides that are joined to form a substantially square tube, the ends of which define guide faces that form an oblique angle with any plane orthogonal to the planar side of the guide block. A pair of magnets within the body of the guide block, each covered by a low friction pad firmly engage the saw and keep it in contact with the guide faces throughout the cutting operation. The guide block also has two orthogonal wing surfaces for positioning the guide block against a face of a board to orient the guide faces either: (a) square to the end of the board and at an angle to its faces, or (b) square to its faces and at an angle to the end of the board. The repositionable clamp is secured to the guide block for clamping it to the board in either of the two alternative positions.Type: GrantFiled: August 31, 2001Date of Patent: August 19, 2003Assignee: Lee Valley Tools, Ltd.Inventor: Steve K. Jones

Patent number: RE38612Abstract: A router table fence having three nesting aluminum extrusions or spars, two of which lie under a longer third spar. By positioning the inner ends of the two lower spars adjacent to a router cutter protruding through a router table, it is possible to provide a fence, particularly when the lower spars are used with wood facings or sub-fences, that can be adjusted to closely surround the cutter. Lateral movement of the fence assembly adjusts the amount of cutter that contacts a workpiece manipulated past the cutter while contacting the fence. The cross sectional shapes of the spars are identical and are generally square, with structure that permits the upper, longer spar to rest on top of, and be attached in a manner permitting it to slide against, the lower two spars. T-shaped slots in each face of the spars accept fasteners that connect the spars together and also accept fasteners for a variety of accessories, such as hold-down devices and shields.Type: GrantFiled: February 28, 2002Date of Patent: October 5, 2004Assignee: Lee Valley Tools, Ltd.Inventors: Edwin C. Tucker, Michael S. McGuire, Leonard G. Lee, John S. Lynn

Patent number: RE38626Abstract: A video camera mounted on a parking enforcement patrol vehicle and connected to a computer near the operator. The system is driven along a patrol route where parked vehicles are governed by a posted time limit. The system enforces the local parking regulation by automatically determining whether or not each parked car has been parked longer than the posted time limit. Violations are detected by applying a License Plate Recognition algorithm to the images. Each license plate number is time-tagged, geo-referenced and entered into a local database. When the patrol vehicle re-traces the patrol route after the posted parking time limit has expired, the database is searched to flag vehicles that were observed at the same location during the previous circuit and therefore in violation of the parking regulations. When the system detects a parking violation, it prints a parking citation that the operator affixes to the offending parked vehicle.Type: GrantFiled: June 21, 2002Date of Patent: October 19, 2004Assignee: Visionary Technology, Inc.Inventor: Peter J. Kielland
