An electrical combination including a power tool, charger and an adapter separate from and connectable between the battery and the tool housing or battery charger to support the battery on the tool housing or the battery charger, the adapter having adapter leads for electrically coupling the battery to the power tool or the battery charger, the adapter having a mechanical lockout for allowing an electrical coupling between the adapter and the power tool while preventing an electrical coupling between the adapter and the battery charger.

Adapter for cordless power tools

A fence system capable of serving as a guide rail assembly for a cutting tool is provided. The system comprises a main beam with integrated or removable guide inserts interlocked by mechanical means that provide a spacing system for various handheld plasma torches. The inserts are customizable to fit the profile of various torch bodies and provide a precise preset gap for optimized cutting. The main beam can also incorporate storage of consumable parts for the torch as well as additional guide inserts.

A portable winch assembly includes a winch mechanism connected to a support structure adapted to be manually transportable. A battery pack is releasably coupled to a remote control unit. The remote control unit is operated to control the winch mechanism. The battery pack and the remote control unit can be electrically connected to the winch mechanism by a flexible power cable, or the battery pack can be mounted with the winch mechanism and a wireless remote control unit can be used to operate the winch mechanism.

A microstrip trombone delay line is used to provide a low cost true time delay device. An array of printed trombone lines arranged in a network is used to implement a linear beamformer. The beamformer forms an array that scans signals in one or more dimensions. Each microstrip trombone delay line includes printed traces on a fixed substrate and a printed trombone line on a movable superstrate. The microstrip trombone delay line may have different dimensions to vary the characteristic impendence at either end for impedance matching purposes. Beamformers using microstrip trombone delay lines and scanning in multiple principal planes require few movable parts and only linear actuators.
