MEANS FOR CLOSING FIELD CIRCUITS OF ROTARY CON-VERTERS; William B. Potter. Schenectady. N. Y. App. filed Sept, 17,1903. By means of a polarized armature the proper polarity of the arma-ture brushes at the instant the field is connected to them, is ensured andby a proper adjustment of a spring the voltage at which the field circuitwill be closed can be adjusted, thus the danger arising from closing a fieldcircuit at the wrong instant is avoided.
