 bürsten   I   noch eine dritte Lamellenbürste p vorgesehen, die mit den beiden   enterez   kurzgeschlossen ist und Strom an einem konzentrisch zur Drehachse in ungefähr de-'gleichen Höhe mit den Schleifbahnen der Wicklungsringe angeordneten Kontaktteller 9 abgibt, von dem er nach einem festen Anschlusspol r fliesst.

   Ausser   de.'Klemme u   sind noch Anschlussklemmen v und w vorgesehen zum Festklemmen und Verbinden der Leitungsenden, wie schematisch in Fig. 4 angedeutete 
PATENT-ANSPRÜCHE :   I.   Regelbarer elektrischer Widerstand mit koaxial ineinander angeordneten Widerstandsspulen, dadurch gekennzeichnet, dass die in bekannter Weise auf Tragkörpern aufgewickelten Spulen an einem gemeinsamen mit unbewickelten Stellen der Tragkörper verbundenen Träger derart befestigt sind, dass zwischen den Spulen ein ringförmiger Hohlraum zum Zwecke der Lüftung verbleibt.

 brush I a third lamellar brush p is also provided, which is short-circuited with the two enterez and delivers current to a contact plate 9 arranged concentrically to the axis of rotation at approximately the same height as the sliding tracks of the winding rings, from which it flows to a fixed connection pole r.

   Besides de.'Klemme u, connection terminals v and w are also provided for clamping and connecting the line ends, as indicated schematically in FIG
PATENT CLAIMS: I. Controllable electrical resistance with coaxially arranged resistance coils, characterized in that the coils, which are wound on support bodies in a known manner, are attached to a common carrier connected to unwound points on the support bodies in such a way that an annular cavity between the coils for the purpose ventilation remains.

2. Regelbarer elektrischer Widerstand nach Anspruch i, dadurch gekennzeichnet, dass die beiden Wicklungsringe unter Zwischenschaltung von Distanzstücken an unbewickelten Stellen durch die gleichen Befestigungsmittel mit dem als Tragbock ausgebildeten gemeinschaftlichen Achsenlager verbunden sind. EMI2.1 Drehachse übereinander angeordneten Stromabnehmer, die über die Wicklungen schleifen, dadurch gekennzeichnet, dass bei Parallelschaltung der Wicklungen ausser den beiden über die Wicklungen schleifenden Stromabnehmern ein dritter, an dem gleichen Tragarm befestigter Stromabnehmer vorgesehen ist, welcher auf einem konzentrisch zur Drehachsr in ungefähr gleicher Höhe mit den Schleifarmen der Wicklungsringe angeordneten Kontaktteller schleift, 2. Adjustable electrical resistance according to claim i, characterized in that the two winding rings are connected with the interposition of spacers at unwound points by the same fastening means with the common axle bearing designed as a support bracket. EMI2.1 Axis of rotation arranged on top of each other pantographs which slide over the windings, characterized in that when the windings are connected in parallel, in addition to the two pantographs which slide over the windings, a third pantograph is provided which is attached to the same support arm and which is located on a concentric to the axis of rotation at approximately the same height grinds the contact plate arranged on the grinding arms of the winding rings,
