Abstract: An energy storage module (ESM) is provided for connecting to a welding or cutting machine (WCM). The ESM has a controller for connecting to a communication link (CM) to communicate with the WCM when the ESM is connected to the WCM. The ESM also has a battery pack to store electrical energy and output DC electrical power to be used by the WCM, under control of the controller. Electrical input power provided to the WCM from an electrical grid or a renewable energy source during a welding or cutting operation can be supplemented or replaced by the DC electrical power from the ESM. The ESM further has regulation circuitry to regulate the DC electrical power output from the battery pack. The controller controls the regulation circuitry based on identification data received over the CM from the WCM to regulate the DC electrical power to be electrically compatible with the WCM.

Abstract: A swell packer sealing element has a wedge on either or both ends that is driven axially when the packer is at the desired borehole location. The wedge releases an end bond of the sealing element and forces the end of the sealing element out radially against the surrounding borehole wall. The actuator for the wedge also forces out an extrusion barrier at the same time. The packer achieves the ability to handle the design differential pressure with aid of the end wedge even as portions of the packer sealing element beyond the end are still swelling into contact with the surrounding borehole wall whether in cased or open hole.
