Smooth, conllnuovs, stoploss speed control. , Rqtjal sensitivity over the entire operating range. KJixi: ' IT WORKS. Motor speed is varied by increasing and sting resistance. This is accomplished by raising and lowering >des and the level of current-carrying electrolyte. A pilot ' transmits draft condition to a lifting mechanism which grols electrode position and electrolyte level. A full resistance provided in only 10 inches of electrode travel. The basic pipit of liquid rheostat operation plus the utilisation of spe- p engineered electrodes gives a linear relationship between [or speed and electrode travel over the complete rheostat range, ^ve the rheostat is not mechanically connected to the motor it located to suit the most convenient plant layout.
