Patent number: 8347678Abstract: A rekeyable lock cylinder assembly includes at least one lock cylinder and a mortise lock adapter. Each lock cylinder includes a cylinder body with a longitudinal axis. A locking bar is disposed in the cylinder body for movement transverse to, and rotationally about, the longitudinal axis. A plug assembly having a tool receiving aperture is disposed in the cylinder body and is rotatable about the longitudinal axis. A plurality of pins and a corresponding plurality of racks are disposed in the plug assembly. A first member is moveable in response to application of a force by a tool received through the aperture to simultaneously disengage all of the plurality of racks from the plurality of pins. The mortise lock adapter includes a housing configured for receiving the cylinder body of the lock cylinder. A mortise lock actuator is coupled to the plug assembly of the lock cylinder.Type: GrantFiled: June 11, 2008Date of Patent: January 8, 2013Assignee: Newfrey, LLCInventor: Gerald B. Chong

Patent number: 8336746Abstract: An archery bow carrying apparatus includes a harness configured to be worn by an archer, the harness having a connection member. A loop member fixedly attaches to the bowstring of the bow at a location offset from the nock point. The connection member is configured to be removably engaged with the loop member. During the carrying of the archery bow, the loop member and the connection member bear at least a portion of the weight of the archery bow.Type: GrantFiled: May 13, 2010Date of Patent: December 25, 2012Inventor: Boyd E. Leach

Patent number: 8291735Abstract: A rekeyable lock cylinder includes a lock cylinder body having an interior void and a plug assembly rotatably disposed in the lock cylinder body. The plug assembly includes a plug body having a keyway. A plurality of racks is movably disposed relative to the plug body. A plurality of key followers is positioned across the keyway and is moveably disposed relative to the plug body. Each key follower is configured to engage a respective rack of the plurality of racks. A key follower rotation member is drivably engaged with each key follower of the plurality of key followers. The key follower rotation member is selectively movable to rotate each key follower of the plurality of key followers to thereby disengage each key follower of the plurality of key followers from the respective rack of the plurality of racks to facilitate a keying of the rekeyable lock cylinder.Type: GrantFiled: March 31, 2011Date of Patent: October 23, 2012Assignee: Newfrey, LLCInventor: Gerry Damikolas

Patent number: 8099988Abstract: A rekeyable lock cylinder includes a plug assembly and a lock cylinder. The plug assembly includes a plug body, a plurality of key followers, a plurality of racks, and a rack carrier that carriers the plurality of racks. The rack carrier is moveable relative to the plug body between a proximal end and a distal end. A cam follower extends outwardly from the rack carrier. The lock cylinder body includes a cylinder wall with the plug assembly rotatably disposed therein, and has a cam track configured on the cylinder wall at an interior surface to guide the cam follower of the plug assembly. The cam track has a ramp portion configured to longitudinally displace the cam follower and the rack carrier as the plug assembly is rotated relative to the lock cylinder body to facilitate selective disengagement of the plurality of racks from the plurality of key followers.Type: GrantFiled: August 9, 2010Date of Patent: January 24, 2012Assignee: Newfrey, LLCInventor: Graham J. Wheatland

Patent number: 8044672Abstract: A method is provided for measuring D-Q impedance of a component of a polyphase power grid connected to a grid node, and evaluating the margin of stability at a node using Nyquist diagrams generated from the measured D-Q impedance data. A generator, coupled to the polyphase power grid, is controlled to induce suppressed-carrier stimulus current into the grid node. Circuitry measures response signals of suppressed-carrier form existing within a bus voltage at the grid node and a branch current of the component being measured. The method includes measuring complex voltage components of the response signals contained in the bus voltage and complex current components of the response signals contained in the branch current to form simultaneous equations that are resolved to determine the D-Q impedance parameters Zqq, Zqd, Zdq and Zdd of the measured component.Type: GrantFiled: March 23, 2009Date of Patent: October 25, 2011Inventor: Michael Lamar Williams

Patent number: 8033150Abstract: A rekeyable lock cylinder includes a cylinder body with a longitudinal axis. A plug assembly is disposed in the cylinder body and is rotatable between a first position and a second position, the plug assembly having a lock face with a tool receiving aperture. A plurality of key followers and a corresponding plurality of racks are disposed in the plug assembly. The plurality of racks is selectively engageable with the plurality of key followers. A first member is coupled to the plurality of racks. The first member is moveable in response to application of a force against the first member by a tool received through the tool receiving aperture. The first member is configured to simultaneously disengage all of the plurality of racks from the plurality of key followers in response to the movement of the first member.Type: GrantFiled: October 3, 2008Date of Patent: October 11, 2011Assignee: Newfrey, LLCInventors: Steven Armstrong, Gerald B.

Patent number: 8033488Abstract: An ergonomic portable pill crusher tool includes an elongate handle having a first axis, and a shaft having an offset portion and a work portion. The offset portion is connected to the handle. The offset portion has a second axis arranged to be oblique with respect to the first axis of the handle at a first angle facing a central portion of the handle. The work portion has a third axis arranged to be oblique with respect to the second axis of the offset portion at a second angle facing away from the central portion, such that an extent of the work portion along the third axis is substantially perpendicular to the first axis of the handle at the central portion of the handle. A distal end of the work portion has a tip to facilitate application of a working force to crush the pill(s).Type: GrantFiled: January 14, 2011Date of Patent: October 11, 2011Inventor: Dolores H Grah
