Patent number: 10660633Abstract: A suture anchor made of a single length of wire that forms a suture retaining loop having two diverging legs, each having a pointed end. The transverse spacing of the diverging legs is greater than the diameter of the bone tunnel. The suture anchor may be spring loaded and set into the bone tunnel so that the distal points of each diverging leg are below the surface of a bone cortex, the sharp distal points of each diverging leg expand out laterally under pressure and penetrate the bone tunnel wall prohibiting removal of the suture anchor. The diverging legs further penetrate the bone tunnel wall in response to applied withdrawal forces.Type: GrantFiled: March 14, 2013Date of Patent: May 26, 2020Inventors: Edwin D. Vyhmeister, Jeff A.

Publication number: 20160039040Abstract: A method of fusing an edge member to a peripheral portion of the metallic component is disclosed. The method initiates with providing an edge forming apparatus, which includes a manipulator, a heating unit, and at least one set of rollers. The manipulator is capable of receiving the edge member and the metallic component. Thereafter, edge member and the metallic component are positioned on the manipulator. After positioning, the heating unit heats a first portion of the edge member and a first section of the peripheral portion. Thereafter, the manipulator is manipulated to facilitate an engagement between the first portion and the first section, by passing the first portion and the first section through the set of rollers. Afterwards, the first portion of the edge member is fused with the first section of the peripheral portion of the metallic component.Type: ApplicationFiled: October 19, 2015Publication date: February 11, 2016Applicant: Caterpillar Inc.Inventor: JEFF A.

Patent number: 8950367Abstract: A cooling fan shroud comprises multiple, functionally identical sections that form a ring-like structure that completely surrounds the fan when the shroud is installed onto an aperture plate or other structure. The shroud makes the cooling system more efficient by improving air flow at a given fan speed by reducing fan tip clearance, and increasing air flow due through the fan. An alternative, single piece shroud is also provided which can be retrofitted to an existing cooling system.Type: GrantFiled: July 30, 2012Date of Patent: February 10, 2015Assignee: Caterpillar Inc.Inventors: Jeff A.

Patent number: 8915708Abstract: A turbocharger includes a turbine section, a compressor section and a bearing section. A turbine wheel and a compressor wheel are mounted on a shaft and the shaft is rotatably mounted in a bore of a housing. A lubrication system circulates lubricant through the bearing section. First and second spaced apart seals are positioned along the shaft. A recess is positioned between the first seal and the second seal to define an air buffer chamber. The air buffer chamber is provided with pressurized air to discourage lubricant leakage past the first seal.Type: GrantFiled: June 24, 2011Date of Patent: December 23, 2014Assignee: Caterpillar Inc.Inventors: Nan Yang, Jeff A.

Patent number: 8784065Abstract: A frictional welding process for joining a titanium aluminide turbine to a titanium alloy shaft is disclosed. The disclosed process includes preheating the turbine to a designated temperature, providing a specially-designed joining interface geometry at the distal end of the shaft and optimizing the frictional welding parameters. The frictional welding is carried out in multiple steps but, while the shaft is being spun by a rotating chuck, two different pressures and two different time periods are used until the narrower portions of the distal end of the shaft have been fused onto the welding surface of the turbine. Then, an additional forging step with yet another engagement pressure between the shaft and the turbine is carried out without rotation of the shaft.Type: GrantFiled: May 24, 2011Date of Patent: July 22, 2014Assignee: Caterpillar Inc.Inventors: Nan Yang, Jeff A. Jensen, Jesus G. Chapa Cabrera

Patent number: 8082730Abstract: An internal combustion engine system includes an engine having an engine housing. The engine system further includes an exhaust system, and a turbine disposed within the exhaust system. A particulate reduction device is disposed in the exhaust system upstream of the turbine. The particulate reduction device includes an exhaust retarder having a flow property which is based at least in part on a residence requirement for combustion of particulates in exhaust gases passing therethrough. The flow property may be a flow restriction property, and the exhaust retarder may include a flow restricting trapping element configured to trap particulates in the exhaust gases. The flow restricting trapping element defines a combustion efficacy to exhaust mass flow and temperature coefficient for the particulate reduction device which is based at least in part on a combustion initiating residence requirement for particulates passing through the particulate reduction device.Type: GrantFiled: May 20, 2008Date of Patent: December 27, 2011Assignee: Caterpillar Inc.Inventors: Nan Yang, Jeff A.
