ABSTRACT:
A rheostat of the kind that comprises a tank containing electrolyte and at least two electrodes, one electrode being connectable to an electric power supply and the other electrode being connectable to apparatus to be fed by the power supply. The electrodes define therebetween an electrolyte flow path and there is associated with the electrolyte flow path operational pumping apparatus providing for a controlled effective circulation of the electrolyte between the electrodes. The rheostat is particularly usable in conjunction with the starting of squirrel-cage motors.
