Publication number: 20140328640Abstract: A bi-metal drill bit includes a body defining a cutting end and a shank end. At least a portion of the cutting end is formed of a first metal section and at least a portion of the shank end is formed of a second metal section that is welded to the first metal section. The first metal section has a first metal having a material hardness that is higher than a second material hardness of the second metal section. One of the first and second metal sections is treated either by coating or oxide treating so as to have a recognizable different appearance than the other of the first and second metal sections. A length to diameter ratio of the first metal section has been optimized to allow electrical resistance welding, provide better strength in the rear end after the tip breaks through a workpiece, and to minimize cost.Type: ApplicationFiled: March 12, 2014Publication date: November 6, 2014Applicant: BLACK & DECKER INC.Inventors: Aland SANTAMARINA, Glen V. STEINBRUNNER, David N. JOHNSON

Patent number: 8845203Abstract: A bearing assembly having improved impact Brinell resistance is provided. Due to a controlled gap between a rotating component and a non-rotating component or a vehicle suspension structure, the non-rotating component or the vehicle suspension structure is permitted to share impact loads caused by a sufficient side impact to the rotating component, thus preventing excessive loads from being transmitted to rolling elements, and providing greater resistance against Brinell impact damage that would generate a noise and/or vibration condition in the bearing assembly. The width of the controlled gap and of the area of potential contact between the rotating component and the vehicle suspension structure or the non-rotating component are optimized to increase impact Brinell resistance while avoiding excessive contact between the rotating component and the non-rotating component or the vehicle suspension structure during extreme cornering maneuvers.Type: GrantFiled: November 6, 2008Date of Patent: September 30, 2014Assignee: Kyklos Bearing International, Inc.Inventors: Steven E. Meeker, David N. Johnson, Connie J. Buynacek, Martin P. Grover

Patent number: 6993681Abstract: A method and system for remote administration of clients performing critical processes are disclosed herein. A client management module is used to monitor a subset of processes performed by a client. When the client management module detects that a process of the subset has terminated or become inoperable, the client management module can restart the process, as well as notify a remote system manager. Additionally, the client management module is adapted to monitor the consumption of system resources by one or more processes. Using fuzzy logic to evaluate the system resource consumptions of one or more system resource types, the client management module can select an appropriate action response to improve the performance of the process and/or notify an administrator of a status of the process. The remote system manager is adapted to monitor a connection with the client.Type: GrantFiled: April 15, 2002Date of Patent: January 31, 2006Assignee: General Electric CorporationInventors: Leon E. Haynes, David N. Johnson

Patent number: 6979129Abstract: A self-lubricating connector or roller is formed by molding a laminated bearing insert in-situ within a nylon support or member. The connector provides a one-piece, self-lubricating device to replace conventional multiple-piece bearing assemblies which typically include a nylon member having an integral metallic sleeve rotatably engaged with a conventional needle or journal bearing. An alternate embodiment of the present invention includes a connector fabricated by press-fitting the laminated bearing insert into a member fabricated from a metallic material. The connectors or rollers of the present invention have several advantages over the prior art, including improved concentricity between the load bearing layer and roller, closer tolerances and elimination of parts and assembly steps.Type: GrantFiled: September 16, 2003Date of Patent: December 27, 2005Assignee: Norton Performance Plastics Corp.Inventors: Richard Farbaniec, Robert J.

Patent number: 6622377Abstract: A wheel bearing assembly for supporting a wheel and apportioned vehicle mass is provided. The assembly includes a spindle member defining a rotational axis with a flange for attaching a wheel and a hub assembly. A bearing assembly has inner and outer bearing members in spaced relationship from one another with a plurality of rolling members interposed between the bearing members to permit relative rotation between the bearing members about the rotational axis. The spindle is deformed around the inner bearing member to prevent axial translation between the spindle and the inner bearing member about the rotational axis. An outer surface of the inner bearing member has a geometric feature for receiving a force applied from a tool during the deformation of the spindle thereby reducing radial deflections of the inner bearing member during the process of deforming the spindle.Type: GrantFiled: October 24, 2000Date of Patent: September 23, 2003Assignee: Delphi Technologies, Inc.Inventors: David N. Johnson, Bruce T. Rockwell, Terence Joseph Kehres, David L. Schoewe, Debbie Sue Wadsworth-Dubbert
