Patent number: 9909715Abstract: This invention provides both a pump and a lubrication and cooling system with a pump which includes a pump housing, a rotor, a relief valve and a bypass valve. The relief valve is configured to relieve pump pressure when the pump pressure is indicative of an abnormal restriction of flow. The bypass valve is configured to direct fluid flow from an outlet chamber of the pump to an intake chamber of the pump when pressure in the outlet chamber is at a value associated with a predetermined speed of rotor rotation.Type: GrantFiled: February 6, 2015Date of Patent: March 6, 2018Assignee: Eaton CorporationInventors: Robert B Craft, Paul J. Mason, Jerry J. Brittan

Patent number: 9835047Abstract: A test blade for use in a blade-release test in which the blade is mounted on a rotatable hub and at least a portion of the blade is released therefrom by the action of a controlled explosion. The blade has a root portion for mounting on said rotatable hub and the root portion comprises a radially inner surface having a channel extending at least partly along or proximal the camber line. The channel is for receiving at least one explosive charge and at least one detonator which may be contained within a charge carrier.Type: GrantFiled: April 22, 2015Date of Patent: December 5, 2017Assignee: ROLLS-ROYCE plcInventors: Christopher M Whitehead, Ewan F Thompson, Paul J Mason, Jeremy N Turner

Patent number: 8505388Abstract: An apparatus for simulating stresses experienced by a rotor blade root in a complementary disc fixture, especially in gas turbine engines. The apparatus comprises a mounting member for receiving a blade speciman having a root. The mounting member has an aperture for receiving the root of the blade specimen, and blade contacting regions on either side of said aperture for holding said blade specimen in said aperture. The apparatus further comprises an actuator for applying a tension load to said blade specimen. The blade contacting regions are undercut such that there is a gap between said blade contacting regions and a main body of said mounting member, whereby the blade contacting regions are able to deflect outward into said gap when a tension load is applied to the blade specimen.Type: GrantFiled: February 23, 2010Date of Patent: August 13, 2013Assignee: Rolls-Royce, PLCInventor: Paul J Mason

Patent number: 7077782Abstract: A continuously variable transmission (CVT) is suitable for replacement of a main transmission box of a compound transmission in a light to medium duty electromechanically actuated truck transmission system. For example, one line-haul truck transmission consists of a five-speed main section and an auxiliary deep reduction box to provide 15 forward speed ratios. The replacement of the five-speed main section with a CVT unit enhances the overall operating efficiency of the system. In one form, the CVT includes a pair of rotatable countershafts mounted to pivot relative to one another. Each of countershafts has a greater diameter disk at one end than the other. Positioned between countershafts are a pair of laterally spaced cones that share a common axis; the greater diameter disk ends of the two countershafts bear against one of the intermediately positioned cones, while smaller diameter disk ends of the countershafts bear against the second cone.Type: GrantFiled: April 16, 2004Date of Patent: July 18, 2006Assignee: Eaton CorporationInventors: Paul J. Mason, Mark A. Kanouse

Patent number: 6361473Abstract: A controller-assisted, manually shifted transmission system (10) utilizes a shift inhibit mechanism (48) to inhibit out-of-synchronous shifts and unintended disengagement of ratios. An intent to shift (ITS) and target ratio (GRT) are determined from a shift lever position sensor (46) and a force sensor (50).Type: GrantFiled: April 27, 2000Date of Patent: March 26, 2002Assignee: Eaton CorporationInventors: Paul J.

Patent number: 6105449Abstract: A control for enhanced manual shifting in a computer-assisted (48) vehicular splitter-type compound transmission (16) having a synchronized main section (16A) shifted by a manually operated shift lever (31) and a controller (42). The splitter section (16B) is located at the input end of the transmission, is provided with a three-position (L, H, N) actuator (46), and is commanded to a splitter-neutral position upon sensing an intent for a main section shift to neutral and remains in splitter neutral until the main section is reengaged to reduce the forces required to synchronize the main section.Type: GrantFiled: July 6, 1999Date of Patent: August 22, 2000Assignee: Eaton CorporationInventors: Thomas A. Genise, Paul J. Mason, Thomas R. Bockelmann
