Improvements in Transforming Continuous Electric Currents

12,820. M³ller, A., and Tudor, H. May 24. Distributing; transformers.-Relates to the transformation of continuous current by means of secondary batteries. The batteries are divided into groups, which are connected to the sections of a commutator, and an equalizing-battery is placed in shunt with the generator or translator. Fig. 1 shows an arrangement for transforming the low - tension current from a generator G provided with an equalizing-battery b. The conductors a, a are connected to the brushes c, c' of a commutator U driven by a motor M. The secondary battery B is divided into groups k .. k , which are connected to the sections f .. f of the inner ring of the commutator. A high-tension current is thus obtained in the conductors e, e . To obtain a low-tension current for the consumers, a similar arrangement of apparatus is employed, but the lamps &c. take the place of the generator G. To prevent sparking at the commutator, a separate contact-breaker F, Fig. 3, is employed. It comprises a disc S fitted with segments corresponding to the contacts of the commutator. Methods of arranging both batteries in groups to obtain any desired ratio of transformation are also described.
