5591. Benitez, C. F. April 14. [Addition to 17,811/14.] Supplying by arrangements of transformers and condensers.-In a modification of the system for generating electric cur- rents described in the parent Specification, vapour converters are dispensed with. In the arrangement shown, three pairs of condensers, 1, A, C and three transformers 2, 5, 25 are used, together with a commutator 38 for completing the circuits in the required order. The condensers 1 are first charged from an external source through the connector 13, which is then turned out of the vertical position so as to disconnect the condensers from the source. On moving the commutator into the position shown, the condensers are discharged through the primary of transformer 5, the secondary of which charges condensers A, C. On moving the commutator through a third of a revolution the condensers C are discharged through the primary of the trans- former 2, the secondary of which is connected to the inner coatings of the condensers A, the outer coatings of which are at this moment connected to the inner coatings of condensers 1. On moving the commutator again through a third of a revolution, the condensers A discharge through the primary of transformer 25, the secondary of which recharges condensers 1, the surplus energy being utilized through another transformer 30 for driving a motor 35 which turns the commutator and for other purposes. In a modification, the condensers A, C are permanently connected together and are charged, as before, from a condenser 1 through a transformer. The condensers A, C are then discharged through the primary of trans- former 25, the secondary of which recharges condenser 1 and furnishes surplus energy to a transformer 30.
