17,811. Benitez, C. F. July 28. Distributing by condensers and transformers.- A transformer primary is connected between a condenser and earth by means of a rotary commutator, and the secondary is connected through an arrangement of condensers and transformers to the first condenser. One side of the condenser 1 is connected to a supply main 13 when the switch 14 is closed, and the other side is connected to the primary 3 of a transformer. The other terminal of primary 3 is connected alternately to earth and the condenser 1 through the brushes 38, 18 of the rotary commutator. On the secondary side 4 is an arrangement of condensers 5, 9 and transformers 7, 70. The circuits include rectifiers a .... f and a spark-gap 6. The commutator consists of three insulating - drums, each having a central conducting strip with two oppositely projecting longitudinal strips, those of the centre drum not being in line with the other two. The Specification states that when the switch 14 is closed and the commutator is in the position shown, the condenser 1 is charged and the primary 3 is energized, while on the secondary side a series of high-frequency currents are induced in the transformer 70, which charge the condenser 9 to a high potential. The system being self- working, the switch 14 may be opened. When the commutator is rotated through a quarter of a revolution, the condenser 1 discharges through the primary 3, and the charge on the condenser 9 is increased. The switch is then closed and the commutator rotated again. The condenser 1 is recharged from the condenser 9, and the currents may be employed to energize the transformer 10 and run the motor 12 to drive the commutator &c. The arrangement of transformers 50, 59 and con- denser 54 may be used in place of the high- frequency arrangement already described.
