Abstract: A handheld pole sander is provided including an elongate body having two ends, the elongate body including a first pole and a second pole made partially of electrically conductive material and capable of sliding in and out of each other in a telescopic manner the first pole and second pole are made from electrically conductive material. An electric motor electrically controlled by control electronics is provided, and a sanding head is attached via a pivot mechanism to a first end of the elongate body. At least one seal is located between overlapping parts of the first pole and second pole. The seal includes an electrically conductive material and provides an electrical connection between the first pole and second pole. Alternatively, at least one electrical contact is provided between the first pole and second pole to provide an electrical connection between the first pole and second pole.

Abstract: A kitchen appliance for food processing, which has a drive shaft, a working part, preferably having a blade, which is provided on the drive shaft, a protective hood having multiple cut-outs in the circumferential direction, which protective hood surrounds the working part and has an opening in the axial direction of the drive shaft, and a preferably cylindrical accessory element. The accessory element has an outer body having a first axial end face and a second, opposite axial end face, and the protective hood, by cooperation with the accessory element, defines a cavity for processing foods which is closed in the circumferential direction of the protective hood. The outer body further has multiple, protrusions projecting inwards in the radial direction, which protrusions can be operatively connected to the cut-outs in the protective hood.
