    PATENT-ANSPRÜCHE:  
1. Dreischenklige Drosselspule bzw. Transformator mit durch   Gleichstrom   oder Wechselstrom niedriger Frequenz veränderlicher Induktanz bei der im Kreise des Gleichstromes bzw. des Wechselstromes niedriger Frequenz ein   grosser induktiver   Widerstand eingeschaltet ist. dadurch gekennzeichnet, dass zum Zwecke der Vermeidung   unerwünschter Spannungen   in der Gleiehstromwicklung (g) bzw. zum Schutz der Gleiehstromapparate eine Kurzschlusswirkung (k) so angeordnet ist. dass sie etwa den gleichen Kraftfluss wie die Gleichstromwicklung umfasst.

    PATENT CLAIMS:
1. Three-legged choke coil or transformer with inductance which can be changed by direct current or alternating current of low frequency, in which a large inductive resistance is switched on in the circuit of direct current or alternating current of low frequency. characterized in that a short-circuit effect (k) is arranged in order to avoid undesired stresses in the DC winding (g) or to protect the DC devices. that it includes approximately the same power flow as the DC winding.
