A battery-powered tool comprising a control circuit, a rechargeable battery connected to the control circuit and configured to provide electrical power to the tool, the battery having a nominal battery voltage, and a receiver circuit connected to the control circuit and configured to be electromagnetically coupled to a transmitter coil structure located external to the tool. The receiver circuit comprises a receiver coil structure having a longitudinal axis that is configured to direct flux induced by the transmitter coil in a transverse direction such that an output voltage of the receiver circuit is provided to the control circuit for charging of the battery, the output voltage being larger than the nominal battery voltage.

The present invention is a handrail catch basket designed for working on the opposite side of a handrail. During operation, the basket is placed under a drop hazard that is being worked on and is placed so as to capture objects that may drop inadvertently. The basket has a chamber to contain tools, and a 360-degree trough around the main chamber to contain the parts or tools, if inadvertently angled while removing. The basket may also have ready anchor points to attach tethers, and stabilizer brackets that will hold onto a handrail and keep it from tipping during use. The base is a strainer which allows water to run through to keep the parts wet which helps reduce radioactive contamination from spreading.

A tensioning device for tensioning a workpiece includes a main body having a chamber, a fluid inlet providing fluid communication between a fluid source and the chamber, a puller member supported in the main body and configured to engage the workpiece, and a piston positioned in the chamber and coupled to the puller member. Movement of the piston moves the puller member along a piston axis in at least a first direction. The tensioning device further includes a sensor coupled to the piston and operative to measure a displacement of the piston and/or the puller member in a direction parallel to the piston axis. The sensor generates a signal indicative of the displacement.
