Abstract: A multi-layered patch including a backing layer, an outer layer, polymer adhesive layers that include a polymer foam and a solvent, and a heating layer that includes a polymer substrate, a heating element and a sensor, and methods of making and using the multi-layered patch.

Abstract: A system for repairing a pipe including a tool, a programmable logic controller and a patch. The tool includes a clamp base having an opening, a first jaw coupled to the clamp base with a first linkage, a second jaw coupled to the clamp base with a second linkage, an operating mechanism carried by the clamp base and operably coupled to the first and second jaws via one or more adjusting links and a junction box carried by the clamp base and operably connected to the controller, wherein the one or more adjusting links are coupled at a first end to either or both of the first and second jaws and at a second end to the operating mechanism, and wherein the first and second jaws are adapted to move, under force of the adjusting links. Methods of repairing pipes are disclosed.

Abstract: A multi-layered composite includes a polymer adhesive layer and a polymer support film layer that becomes intimately incorporated with the polymer adhesive layer upon application of heat.

Abstract: A tool for use on a generally tubular workpiece includes a clamp base having an opening, a first jaw coupled to the clamp base with a first linkage and a second jaw coupled to the clamp base with a second linkage, a translation mechanism disposed on or within the clamp base operatively coupled to the first and second jaws via one or more adjusting links, whereby the first and second jaws are adapted to move, under a force communicated by the adjusting links and the linkages, within the opening between an open position in which the respective bottom ends of the first and second jaws are spaced apart to a closed position in which the respective bottom ends of the first and second jaws are abutting.

Abstract: A tool for gripping, clamping or holding an object, wherein the tool has a handle portion, a linkage portion and a working portion, and wherein the working portion includes two workpiece contacting surfaces, at least one of the surfaces shaped to generally conform to at least a portion of the outer surface of a workpiece to be clamped, gripped or held. In some embodiments, at least one of the workpiece contacting surfaces is adapted to provide a treatment to a workpiece being clamped, gripped or held.
