The process produces a bushing with its internal surfaces accurately coaxial, and with the external surface accurately formed to the required diameter.Type: GrantFiled: July 2, 2003Date of Patent: January 18, 2005Assignee: Tsubakimoto Chain Co.Inventors: Yusuke Haga, Toru Okabe, Nobuaki Haga

Patent number: 6842983Abstract: A pair of gardening shears includes two expandable handles, each handle being formed of an oval outer tube, an oval inner tube, and a grip rotatably fastened to the lower end of the outer tube. The inner tube is slidably fitted at the lower end into the upper end of the outer tube in conjunction with a locating structure including a threaded rod fastened at the lower end to the grip, an upper arresting block, a lower arresting block, and a spring located between the two arresting blocks, which are actuated by the threaded rod to arrest the inner tube at the time when the grip is turned counterclockwise. The inner tube is relieved of the pressures exerting thereon by the two arresting blocks at the time when the grip is tuned clockwise.Type: GrantFiled: February 10, 2003Date of Patent: January 18, 2005Assignee: Ho Cheng Garden Tools Co., Ltd.Inventor: Sheng-Ming Hsu

Patent number: 6842984Abstract: A spooless trimmer head which utilizes finite lengths of trimmer line inserted through apertures in the trimmer head housing. The lines are thick, strong, long lasting and easily replaced when worn. One end of each line extends from the trimmer head to rotate and cut vegetation. The line includes a collar having a flange formed on an opposite end to retain a distal end of the line in the trimmer head housing. The line is crimped to the collar approximately ? the distance from the collar to the distal end of the line. The crimping location in combination with the position of the flange of the collar reduce the stress and strain on the trimmer line and enhance the longevity of the line.Type: GrantFiled: November 7, 2000Date of Patent: January 18, 2005Assignee: Weed Tiger, Inc.Inventors: Mary Ann Johnson, Richard O. Grant

Patent number: 6842986Abstract: A cutting tool includes an elongate handle to be grasped by a user, and an elongate blade connected to the elongate handle. The elongate blade includes a downwardly sloping proximal portion extending outwardly from an end of the handle, and a linear distal portion extending substantially parallel to and downwardly offset from an axis defined by the elongate handle and ending in a tapered tip. The downwardly sloping proximal portion may have a sharpened lower edge, and the linear offset distal portion may have a sharpened lower edge. In some embodiments, the elongate blade may have a length of less than about twelve inches so that the cutting tool is a knife, and in other embodiments, the elongate blade may have a length of greater than about twelve inches so that the cutting tool is a sword.Type: GrantFiled: November 15, 2002Date of Patent: January 18, 2005Inventor: Christopher A. Holler

Patent number: 6842987Abstract: A brake triggering device with a pivotably mounted trigger arm (1) located in connection to a handheld working tool's, mainly a chain saw's (2), rear handle (3), with a throttle control (4) and a handle opening (5) located below the handle (3), so that the trigger arm (1), when the saw changes inclination in relation to the operator's forearm, e.g. at the event of kickback or fall, is actuated by the operator's hand or arm, whereby the trigger arm (1) via a transfer mechanism actuates a brake (9) so that this stops the movement of the saw chain. The pivot (10) of the trigger arm is located in connection to a front (11) or a bottom (12) side of the handle opening (5).Type: GrantFiled: November 20, 2000Date of Patent: January 18, 2005Assignee: Aktiebolaget ElectroluxInventors: Pär Martinsson, Peter Björkman

Patent number: 6842988Abstract: A locking assembly for a portable, engine-powered, hand tool, such as a clearing saw. To facilitate removal and installation of a rotatable cutting tool (13), a rotatable shaft (11) driving the cutting tool is locked against rotation by a movable locking pin (17) of magnetic material that is secured in a locking position by a magnet (19) carried by a housing of the tool supporting the rotatable shaft.Type: GrantFiled: March 7, 2001Date of Patent: January 18, 2005Assignee: Aktiebolaget ElectroluxInventor: Jörgen Johansson

Patent number: 6842989Abstract: An improved bow sight adjustment mechanism for use with an archery bow is provided. The bow sight adjustment mechanism includes the provision of a dowel pin or similar article disposed between a slide lock and a slide stop to maintain a spaced apart relationship. The dowel pin also extends through the slide with a flexible bushing disposed between the dowel pin and the slide to minimize inadvertent movement of the bow sight adjustment mechanism which could effect the position of the bow sight.Type: GrantFiled: September 9, 2003Date of Patent: January 18, 2005Inventor: Jeffrey J. Wuthrich

Patent number: 6842990Abstract: The invention relates to a device for measuring lateral displacement of a casing in a vertical bore and includes an inclinometer probe, a cable, and a cable reel with electronics mounted in the reel hub. The probe contains two servo-accelerometers, a microprocessor and an electrical circuit. The servo-accelerometers provide analog signals that indicate the inclination angle of the vertical bore hole. The electrical circuit converts the analog signal from each servo-accelerometers to a digital signal which is read by the microprocessor. The microprocessor analyses the data and transmits the digital encoded data over a twisted-pair cable to a digital display unit connected to the cable reel hub. DC power for the probe is provided by the electronics in the reel hub over the same twisted-pair cable.Type: GrantFiled: June 19, 2003Date of Patent: January 18, 2005Inventor: Robert M. Taylor

Patent number: 6842991Abstract: An improved method, system, and device for a compass combining an electronic magnetic compass and an angular velocity sensing gyroscope. One aspect of the invention integrates an angular velocity output signal from an angular velocity sensor or rate gyroscope to determine the angle of motion. An initial magnetic heading is obtained from a geomagnetic sensor and used as a reference for the integrated angular velocity signal. A geomagnetic heading signal is blended with the angular velocity output signal at an adaptive time interval. The adaptive time interval is increased if the reliability of the magnetic field improves and decreased if the reliability of the magnetic field degenerates. Additionally, dynamic calibration of the angular velocity sensor may be performed to correct for gyroscope bias (zero offset), and/or gyroscope scale factor or gain.Type: GrantFiled: July 11, 2003Date of Patent: January 18, 2005Inventors: Robert W. Levi, Robert R. Marshall
