Patent number: 9316055Abstract: In one aspect, a drill bit is disclosed that in one embodiment may include a bit body, a rotating cutter on the bit body, and a metallic seal between the bit body and the rotating cutter that includes a first seal member, a second seal member having a first end in sealing contact with the first seal member, a second end fixed relative to the first end and a bias member between the first end and the second end that adjusts the load on the first seal member in response to external load applied on the drill bit.Type: GrantFiled: May 3, 2013Date of Patent: April 19, 2016Assignee: BAKER HUGHES INCORPORATEDInventors: Chih Lin, Aaron J. Dick, Jon D. Schroder, Anton F. Zahradnik, Alejandro Flores, Robert D. Bradshaw

Patent number: 8978786Abstract: An earth boring drill bit designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg from a plurality of pre-manufactured legs; selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having a slot for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.Type: GrantFiled: November 4, 2010Date of Patent: March 17, 2015Assignee: Baker Hughes IncorporatedInventors: Don Q. Nguyen, Anton F. Zahradnik, Rudolf C. Pessier, Mark P. Blackman, Robert D. Bradshaw, Scott A. Young, Ronny D. McCormick, Shyam Anandampillai, Michael S. Damschen, Robert J. Buske

Patent number: 8769132Abstract: A system for implementing a failover policy includes a cluster infrastructure for managing a plurality of nodes, a high availability infrastructure for providing group and cluster membership services, and a high availability script execution component operative to receive a failover script and at least one failover attribute and operative to produce a failover domain. In addition, a method for determining a target node for a failover comprises executing a failover script that produces a failover domain, the failover domain having an ordered list of nodes, receiving a failover attribute and based on the failover attribute and failover domain, selecting a node upon which to locate a resource.Type: GrantFiled: September 27, 2010Date of Patent: July 1, 2014Assignee: Sony Computer Entertainment America LLCInventors: Padmanabhan Sreenivasan, Ajit Dandapani, Michael Nishimoto, Ira Pramanick, Manish Verma, Robert D. Bradshaw, Jr., Luca Castellano, Raghu Mallena

Patent number: 8307920Abstract: An earth boring drill bit that includes a cutting cone with a cutting disk. Compacts are inserted within the disk having a chisel shaped end set flush with the cutting disk periphery. The compact crests and cutting disk periphery form a generally seamless cutting surface. The cutting cone can further include cutting teeth thereon also having flush mounted compacts. The compacts can be made from a material such as cemented carbide, hardfacing, tungsten, tungsten alloys, tungsten carbide and the cutter made from steel.Type: GrantFiled: August 13, 2009Date of Patent: November 13, 2012Assignee: Baker Hughes IncorporatedInventors: Robert J. Buske, James L. Overstreet, Thomas M. Stefanik, Shyam Anandampillai, Robert D. Bradshaw

Publication number: 20110290560Abstract: A drill bit with a bit body having a central bore in communication with a plurality of nozzles for directing drilling fluid; a plurality of cutters defining a cutting face of the bit; and a passageway extending from the central bore toward the cutting face, such that excessive wear of the cutting face opens the passageway to allow the drilling fluid to flow therethrough, thereby reducing a surface pressure of the drilling fluid and indicating excessive wear of the bit. The passageway may extend to adjacent, or within one half inch or three inches of, the cutting face, such that excessive wear opens the passageway to the cutting face. In some cases, the passageway may actually extend through the cutting face with a plug inserted into the passageway at the cutting face to prevent the drilling fluid from exiting the passageway absent wear of the bit.Type: ApplicationFiled: June 1, 2010Publication date: December 1, 2011Applicant: BAKER HUGHES INCORPORATEDInventors: Robert J. Buske, Mark Philip Blackman, John F. Bradford, Michael S. Damschen, Robert D. Bradshaw, Rudolf C. Pessier

Publication number: 20010011265Abstract: A method and apparatus are provided for dynamically organizing and tracking website content during its deployment. Organizing and tracking may be done internally to a website development system during development and externally to outside destinations such as production servers that provide access to websites via the Internet or intranet. The method of internal deployment includes the process of deploying data among workstations, storage areas, such as a backing store, staging areas, editing areas and other internal areas during the development of website content. According to the invention, a tracking system is able to track such changes as the content is being created, including information regarding their source and history. The method of external deployment includes different schemes for deploying the finished website content to one or more destinations, such as production servers, including a method for tracking the external deployments as to what content is sent, to where and by whom.Type: ApplicationFiled: November 29, 2000Publication date: August 2, 2001Inventors: William G. Cuan, Kevin Cochrane, Gajanana Hedge, Britt H. Park, Robert D. Bradshaw, Jr., James H. Koh
