Abstract: An extraction electrode arm includes first and second ends spaced apart along a longitudinal axis and first and second sides spaced apart along a lateral axis. The arm also includes first and second surfaces apart, extending longitudinally between the first and second ends and laterally between the first and second sides. The arm further includes a base portion extending from the first end toward the second end and extending between the first and second sides, an end portion longitudinally spaced apart from the base portion and extending to the second end, and a diagonal shank portion extending between the base portion and the end portion and extending laterally from a first diagonal surface region on the first side to a second diagonal surface region on the second side. The diagonal shank portion has a shank thickness that extends laterally between the first and second diagonal surface regions.

Abstract: A connecting device for detachably connecting electrical connections, for example between a rechargeable battery and an electrical power tool or a rechargeable battery and a charging device. The connecting device includes a carrier unit and at least one receptacle connectable to the carrier unit. A receptacle as part of and for connection to a connecting device. A carrier unit as part of a connecting device and for accommodating at least one receptacle.

Abstract: A hand-held machine tool has an integrated tool or a tool holder to receive a tool. An electric motor drives the tool or the tool holder. A battery pack for supplying power to the electric motor can be pushed into a guide in a first direction. Electrical contacts are disposed in a contact holder being offset with respect to each other in a second direction. A mounting for the contact holder holds the contact holder so that it can move in the first direction-and in a third direction with respect to the mounting. The first direction, second direction and third direction are orthogonal to each other in pairs. A spring acts upon the contact holder with a force opposite to the first direction. An end face oriented opposite to the first direction is provided with a centerer which cooperates with a centering support on the battery pack in order to prevent a relative movement between the end face and the battery pack in the third direction.

Abstract: A communication network has a plurality of mutually connected network nodes in which in each case network data relating to the network topology of the entire communication network are maintained. Depending on the network data, routing tables for connection paths to all remaining network nodes are created. If an event that influences the network topology of the communication network occurs, on the one hand the network data maintained therein are updated by the network node detecting the event. On the other hand, a broadest message corresponding to the event is transmitted to the other network nodes, following the reception of which the respective network nodes update the network data maintained therein.
