Claims (1)

PATENT-ANSPRÜCHE : 1. Mit einem leitenden Überzug oder einer Metallisierung für Stromanschlusszwecke zu versehende Kolbenstäbe oder-körper für elektrotechnische Verwendungen, dadurch gekennzeichnet, dass diese an Stirnflächen eine gerauhte, gegebenenfalls in eine glatte Fläche übergehende Oberfläche aufweisen, auf welche die leitende Verkleidung oder Metallisierung aufgebracht wird. PATENT CLAIMS: 1. Piston rods or bodies for electrotechnical uses to be provided with a conductive coating or metallization for power connection purposes, characterized in that they have a roughened surface on their end faces, possibly merging into a smooth surface, on which the conductive lining or metallization is applied. 2. Verfahren zur Herstellung von Kohlenstäben u. dgl. nach Anspruch 1, dadurch gekennzeichnet, dass ein aus noch weicher Kohle erzeugter Formkörper vor dem Erhärten an einer oder mehreren Stellen seiner Länge Kerben erhält und nach dem Erhärten an diesen Stellen gebrochen wird, um rauhe Bruch- flächen zu ergeben, welche in beliebiger Weise mit einem leitenden Überzug od. dgl. versehen werden. EMI2.1 2. Process for the production of carbon rods u. The like. According to claim 1, characterized in that a molded body produced from still soft coal receives notches at one or more points along its length before hardening and is broken at these points after hardening in order to produce rough fracture surfaces, which in any desired Way with a conductive coating or the like. Be provided. EMI2.1
