Patent number: 6779251Abstract: An assembly method for a vehicle anti-theft key having an embedded resistor pellet is provided. The resistor pellet includes a flange at one end which abuts one side of the key blade when the opposed end of the pellet is inserted into a through opening formed in the shank portion of the key blade. With the resistor pellet loosely positioned within the through opening, a second flange is attached to the end of the pellet that was inserted through the through opening, thereby capturing the pellet within the through opening by the two opposed flanges. In one embodiment, the second flange is formed in place by employing a polymeric molding process, such as a thermoforming injection molding process. A handle for the key is efficiently formed substantially simultaneously with the second flange using the same polymeric molding process.Type: GrantFiled: October 29, 2001Date of Patent: August 24, 2004Assignee: Hurd CorporationInventors: David C. Banks, Charles C. Edwards

Publication number: 20030132831Abstract: The design of a vehicle anti-theft key with transponder enhances manufacturability and protects the transponder from damage due to mechanical shock. The key includes a shank, a transponder, a shuttle, and a head. A transponder recess formed in the shuttle is sized to tightly receive the transponder, and a shank recess formed in the shuttle is configured to receive one end of the key shank. The key is assembled by inserting the transponder in the transponder recess and the key shank in the shank recess. A key head is then positioned about the shuttle, transponder, and shank end, preferably by means of a polymeric molding process. The transponder recess and shank recess are configured to ensure proper positioning of the transponder and key shank in their respective recesses.Type: ApplicationFiled: January 16, 2002Publication date: July 17, 2003Inventors: David C.

Patent number: 5122146Abstract: Fracture reduction tool is disclosed for use with a guide wire for reducing a bone fracture. The guide wire is of a uniform diameter and has a beaded end for placement into the medullary canal. The tool includes an elongated hollow shaft which can be passed into the medullary canal of the fractured bone through an entry hole prepared in the bone. The shaft has a bore along its length through which the guide wire can selectively pass. The shaft and/or the guide wire can be manipulated into and within the respective medullary canal portions of the fractured bone by translational and/or rotational movements so as to reduce the fracture. The tool also includes a measurement sleeve which moves over the shaft and provides a determination of the length of a nail to be inserted into the medullary canal of the reduced bone. A handle for the proximal end of the shaft allows for ease in manipulation of the shaft and guide wire.Type: GrantFiled: February 4, 1988Date of Patent: June 16, 1992Assignee: Pfizer Hospital Products Group, Inc.Inventors: Michael W.

Patent number: 5001914Abstract: A pick-resistant lock having a housing and a keyway cylinder rotatably mounted within the housing includes a plurality of tumblers and a lock bar associated with the cylinder to render picking of the lock difficult by conventional techniques. The housing has a cylinder-accepting bore provided with a pair of locking grooves arranged so as to face one another. The tumblers and lock bar are movable into and out of locking relationship with a corresponding one of the locking grooves and along parallel paths when the cylinder is positioned in a lock mode position. Springs mounted within the cylinder urge the lock bar and tumblers against one another and toward positions out of the locking grooves while maintaining the lock bar in a locked relationship within its corresponding locking groove so that the cylinder is prevented from rotating.Type: GrantFiled: July 24, 1990Date of Patent: March 26, 1991Assignee: Hurd Lock and Manufacturing Co., Inc.Inventor: Charles C.

Patent number: 4567884Abstract: This invention provides a spinal hook comprising a body having a rod receiving bore therethrough, a connecting portion and a shoe portion, the connecting portion extending along a plane approximately normal to the axis of the base and the shoe portion extending in a plane from the connecting portion and terminating in a tip on one end and joined to the connecting portion on the other end. Preferably, the side of the body facing the shoe portion has a convex curved outer surface to allow a closer fit to a vertebra to which the hook is attached. In preferred embodiments of the invention, the tip of the shoe is disposed closer to the body than the remainder of the shoe by either forming an acute angle between the shoe and the connecting portion or bending the tip of the shoe. The shoe may be tapered in both width and thickness and the connecting portion may be tapered in width from the body to the shoe to provide better fit between the hook and the vertebrae.Type: GrantFiled: December 1, 1982Date of Patent: February 4, 1986Inventor: Charles C.
