Patent number: 11883883Abstract: It has been found that duplex monolithic parts can be manufactured in high volume at low cost by using powder metal technology to mold and sinter an inner component of the part into an outer component of the part. This technique reduces the cost of manufacturing intricate metal products by taking advantage of the attributes of powder metal technology in making the inner component of the part. The outer component of the part can be wrought machined, stamped or forged, or made by double press double sinter or forging a powder metal component of the part. In any case, this technique can beneficially be used in making a wide variety of toroid parts, such as gears, clutches, sprags, bearing races, one-way diodes, and the like.Type: GrantFiled: July 28, 2021Date of Patent: January 30, 2024Assignee: Keystone Powdered Metal CompanyInventors: Gary L.

Publication number: 20190321891Abstract: It has been found that high density articles having improved strength, corrosion resistance, better durability, and decent magnetic characteristics can be manufactured from a ferritic stainless steel powder using a novel method. This technique is especially beneficial in manufacturing parts, such as, reluctor rings, tone wheels, trigger wheels, pump impeller blades, and EGR valves, in large quantities. This method involves (1) compacting the ferritic stainless steel powder in a mold into a green article, (2) sintering the green article at an elevated temperature under vacuum or a reducing atmosphere to produce a sintered article, and (3) forging the sintered article under a reducing or an inert gas atmosphere to a density of greater than 7.5 g/cc in the presence of a graphite free lubricant to produce the high density article.Type: ApplicationFiled: May 10, 2018Publication date: October 24, 2019Applicant: Keystone Powdered Metal CompanyInventors: Gary L.

Patent number: 10443343Abstract: An extrusion ring is attached at a mandrel end to a gage ring as well as a softer ring that is disposed between the extrusion ring and the mandrel. The softer ring acts as an extrusion barrier along the mandrel. On setting the softer ring protects a free end of an extrusion ring from contact with the sealing element by extending axially at least as far as the extrusion ring and preferably further. The sealing element being softer than the adjacent softer ring allows the extrusion ring to push the softer ring out past the end of the extrusion ring and allows the softer ring to fill a void space adjacent the free end of the extrusion ring and to the sealing element. Relative motion between the rings at the attachment location is prevented.Type: GrantFiled: August 10, 2017Date of Patent: October 15, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: James C. Doane, Gary L. Anderson

Patent number: 10329868Abstract: An articulated debris barrier folds on itself to extend radially to span a surrounding annular gap when the tool associated with it is set. The debris barrier can be used with a packer or bridge plug. The set position of the packer or plug is locked and another lock holds the extended position of the debris barrier. The debris barrier lock can be a snap ring that extends into a groove brought into alignment with it during the setting. Alternatively the lock for the debris barrier can be a body lock ring. In either case, release and retrieval of the packer or plug involves undermining of the locking feature for the debris barrier so that the debris barrier can extend while retracting from the borehole wall so that the barrier and the associated packer or plug can be removed together.Type: GrantFiled: August 28, 2015Date of Patent: June 25, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Christopher J. Limb, Frank J. Maenza, Nicholas S. Conner, Robert J. Taylor, Gary L. Anderson
