20060293106 - Double inserted u-joint seal: The present invention relates to a seal used in a U-joint assembly. A compressible annular seal has two annular legs radially spaced apart with a rigid insert at least partially disposed within each leg to provide a desired loading. The inner leg creates a first loading against the relatively stationary... Agent: Freudenberg-nok General Partnership Legal Department

20060293107 - U-joint seal spring system: A U-joint system that advantageously allows for limited relative movement between the cups and the trunnions while avoiding excessive vibration. The U-joint system utilizes a biasing member, exhibiting either or both spring and damping characteristics, that is preloaded to create a desired axial stiffness between the cups and trunnions. The... Agent: Freudenberg-nok General Partnership Legal Department

20060293108 - Solid prop rod of folding type seat: A sold prop rod for a folding-type seat includes a prop rod body having an end portion, a lock nut coupled to the end portion, a housing engaged with the lock nut, and a rotating member disposed between the end portion of the rod body and the lock nut to... Agent: Gardner Carton & Douglas LLP Attn: Patent Docket Dept.

20060287115 - Torsional vibration dampener: A torsional vibration dampener for dampening torsional vibrations of a rotationally driven shaft. A hub is axially connected to the shaft, and a rotationally symmetrical body of inertia that acts as a vibrational mass is connected to the hub by a rubber elastic ring. The body of inertia comprises a... Agent: Robert W. Becker & Associates Suite B

20060287116 - Drive shaft coupling: Disclosed is a torque-transmitting coupling assembly and method, as well as flexible surgical reamers having such assemblies. The reamers employ a fitting with radially flexible member, e.g., a split collet or a super-elastic collar that receives an elongated tubular shaft of super-elastic alloy. A compression sleeve is applied to the... Agent: Moetteli & Associates Sarl

20060281562 - Shaft-hub connection: A shaft-hub connection for transferring a torque between a shaft (1) and a hub (3) with the aid of at least one drive element (2). To enable a torque transfer which is practically resistant to wear, even under the effect of transversal forces, the contact surface between the shaft and... Agent: Davidson, Davidson & Kappel, LLC

20060281563 - Coupling device for coupling rotatable bodies and transmission system including a coupling device: A coupling device including first and second rotatable bodies (1, 3), a plurality of engagement members (27,28) for selectively coupling the first and second rotatable bodies together to transfer drive between the rotatable bodies, and a guard device (2) for preventing the engagement members from coupling the rotatable bodies in... Agent: Knobbe Martens Olson & Bear LLP

20060281564 - Tripot joint retainer: A stroking constant velocity universal joint assembly is provided including a drive member having a plurality of circumferentially spaced rotatable drive elements, and a drive housing disposed about the drive elements. The drive housing has an inner wall formed with a plurality of circumferentially spaced drive channels. The drive channels... Agent: Delphi Technologies, Inc.

20060281565 - Constant velocity joint having fixed center and crossed grooves: A constant velocity counter track joint having an outer joint part with outer ball tracks having first tracks opening toward the aperture end and second tracks opening toward the attaching end. The center line of the second tracks, in departs, radially inwardly, a first reference radius centered in the point... Agent: Artz & Artz, P.C.
