| 20120040439 | Use of Prokaryote Viruses to Remediate Bio-Fouling - This invention provides a process for control in oil and gas wells and related facilities of prokaryote caused souring, fouling and corrosion by reduction of problematic prokaryotes with naturally occurring lysing organisms, particularly sulfate-reducing prokaryotes by proliferating suitable virulent lysing organisms under conditions in which problematic prokaryotes thrive, including in a gas production wellbore. The process provides in situ proliferation of virulent lysing organism in a wellbore by providing both virulent lysing organisms and their host prokaryotes to selectively grow an effective control amount and concentrations of lysing organisms in a well formation. | 02-16-2012 |

| 20090123258 | Tire lifting and mounting tool - The present invention, a tire mounting device, is a lifting and transporting device for the facilitating the removing and replacing of a tire. The tire mounting device comprises a cross assembly, handle assembly, left fork assembly, and right fork assembly. The handle assembly is perpendicularly rigidly attached to the cross assembly. The left fork assembly and right fork assembly are rigidly attached to opposing ends of cross assembly which extends horizontally. An obtuse angle is disposed in an intermediate position with each fork assembly. Tire supports the underside of each fork assembly to allow for the transporting the tire upon the tire mounting device. | 05-14-2009 |

| 20080247876 | Soft In-Plane Tiltrotor Hub - A rotor hub assembly for a rotary-wing aircraft has a central member and a plurality of blade grips adapted for attaching rotor blades to the central member. The blade grips are pivotally attached to the central member and are capable of pivoting about a pivot axis generally normal to a plane of rotation of the blades. The pivoting allows for in-plane motion of the blades relative to the central member. A damper is operably connected to each blade grip for damping the in-plane motion of the associated blade, each damper being selectively switchable between at least two spring rates. | 10-09-2008 |
| 20090179107 | Yoke with Notched Arm Roots - A yoke for a rotary wing aircraft rotor system has a plurality of arms, each arm having a root. Each root has a notched portion configured to allow passage of a portion of a blade-pitch control system through the notched portion. | 07-16-2009 |
| 20090325718 | Constant Velocity Joint for Tiltrotor Hubs - A constant-velocity joint is configured for use with a rotary-wing aircraft having at least one engine. A driver is coupled to an output shaft of the engine, the driver being rotatable about an axis. A yoke is at least partially rotatable relative to the driver about a first center of rotation, the center of rotation being located on the axis. A plurality of upright links couple the yoke to the driver, each link being translatable relative to the yoke, the driver, or both. Each link is also rotatable relative to the yoke, the driver, or both, about a second center of rotation. | 12-31-2009 |

| 20110274550 | Yoke and Bearing Fitting Assembly for Rotors - A yoke and bearing fitting assembly for a multi-blade aircraft rotor is disclosed. The assembly has a yoke having arms extending generally radially from a central portion of the yoke, the arms each having opposing surfaces. An aperture is formed in each arm and extends between the surfaces. A bearing fitting has a body configured for insertion into the aperture of the yoke and has two rims protruding from a periphery of the body, the body also having a bearing mount adapted for mounting a pitch change bearing assembly to the yoke. Each rim abuts one of the surfaces of the associated yoke arm when the bearing fitting is installed within the aperture, so as to create clamping forces between the rims and the arm and the arm. The bearing fitting transmits forces from the pitch bearing assembly into the yoke. | 11-10-2011 |

| 20100009764 | Rotary-Wing Aircraft Torque Coupling with Pad Bearings - A torque coupling for a rotor head of a rotary-wing aircraft is configured for rotation with a mast and for causing rotation of an attached yoke. The coupling has trunnions that rotate with the mast and extend generally radially. Pad-bearing assemblies each have a central member coupled to one of the trunnions with a laminated spherical bearing and have laminated pad bearings affixed to opposing sides of the central member. The laminated bearings have alternating rigid and elastomeric layers. A bearing mount is affixed to each pad bearing and is connected to a yoke for rotating the yoke with the mast. The pad-bearing assemblies allow for relative motion between each central member and the associated trunnion and between each central member and the bearing mounts through elastic shear deformation, and this allows for gimballing of the attached yoke relative to the mast. | 01-14-2010 |
| 20110116936 | Method of Making a Rotor Yoke and Rotor Yoke Thereof - A method of making a rotor yoke includes preparing a cured composite rotor yoke preform on a single-sided curing tool and machining at least one portion of the cured rotor yoke preform to form a rotor yoke. In one embodiment, preparing the cured composite rotor yoke is accomplished by applying successive layers of uncured polymeric composite material to a single-sided tool in a configuration to produce an uncured rotor yoke preform; disposing a semi-rigid caul to an untooled side of the uncured rotor yoke preform; enclosing the uncured rotor yoke preform and the semi-rigid caul by substantially hermetically sealing a vacuum bag to the tool; substantially evacuating a volume defined by the vacuum bag and the tool of air; and heating the uncured rotor yoke preform, sometimes under pressure, to form the cured composite rotor yoke preform. | 05-19-2011 |
