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 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.
