20090309355 | DOUBLE COVER-CENTER CUSHION DECOUPLER - A sealed coupling for connecting two pipe ends include two operating covers for respective connection to respective pipe ends, and elongated bellows having respective ends and a damping element supported by respective rims of said covers, said damping element disposed radially outwardly of said bellows and oriented centrally of said respective bellows ends for dissipating forces on said coupling uniformly across said bellows. | 12-17-2009 |
20090285626 | FLEXIBLE ELEMENT WITH INTEGRAL OUTER SHIELD AND/OR INNER LINER - A flexible bellows used in a pipe coupling includes composite convolutions having integral extensions forming one or both of an outer shield or inner liner to enhance performance of the coupling. Embodiments incorporate dampers, hangers and convolution modifications. Various embodiments are disclosed. | 11-19-2009 |
20090284006 | SEALED FLEXIBLE COUPLING WITH TORSION ACCEPTANCE - A coupling has respective support elements extending respectively from each coupling end toward the other, but not directly connected to each other. Radially oriented ends of these elements define a pocket capturing a cushion therein. A non-metallic bellows operably covers the coupling. An optional thermal shield is disposed between the bellows and the support element. | 11-19-2009 |
20090283357 | ADJUSTABLE TUBULAR NVH DAMPER AND TORSION ABSORBER - Respectively tapered and threaded pipe ends are rotated respective to each other to connect the pipe ends and progressively compress a yieldable damper sleeve therebetween as the pipes are rotated. NVH and torsional forces from one pipe end to another are suppressed. | 11-19-2009 |
