Abstract: A well bladder is used to seal wellbores from intrusion. The well bladder is inserted, threaded, or otherwise arranged into the wellbore or an opening into the wellbore, and then expanded against the wellbore to seal against intrusion. The well bladder includes one or more layers, one or more axial sections, and one or more azimuthal sections. For example, the well bladder may be constructed from polyurethane, reinforcement, fabric, rubber, plastic, a composite material, or other flexible material. In a further example, the well bladder may include layers, mesh, fibers, stitching, or other suitable construction. In some embodiments, the well bladder may include a port configured to allow pressurization of the inner volume, a sensor configured to sense one or more properties of the well bladder, or both. A system may be configured to monitor the well bladder over time to ensure that the well bladder maintains the seal.

Abstract: A rod for the suspension system of a motor vehicle such as a bus which maintains fixed points of the chassis and frame or body in a fixed point to point alignment in the vehicle suspension system comprising a rod having openings at each end for an interference fit attachment to predetermined points or dowels, in which the openings are defined by a freely rotating bushing that is surrounded by a concentric cast polyurethane interface that is bonded to an inner concentric circular opening surface at the end of the rod. The rod is a replacement for transit bus torque rods.
