116 او کے A, in this figure, represents any source of alternating current, the potential of which is raised by a transformer of which a is the primary and b the secondary. The ends of the secondary circuit S are connec ted to the terminal plugs K, K, of an apparatus similar to that of Figures 1 and 2, and having segments rotating in synchronism with the alternations of the current source, preferably, as above described, by being mounted on the shaft of the generator, when the conditions so permit. The plugs K, K, are then adjusted radially so as to approach more or less the path of the cuter edges of the segmental disk, and so that during the passage of each segment in front of a plug a spark will pass between them which completes the secondary circuit, S. The box, or the support for the plugs K, is adjusted angularly so as to bring the plugs and segments into proximity at the desired instants with reference to any phase of the current wave in the secondary circuit, and fixed in position in any proper manner. To the plugs K, K, are also connected the terminald of a condenser or condensers L, so that at the instant. of the rupture of the secondary circuit S by the cessation of the sparks the energy accumulated in such circuit will rush into, and charge, the condenser. A path of low self-induction and resistance, including a primary M of a few turns, is provided to receive the discharge of the condenser, when the circuit S is again completed by the passage of sparks, the discharge be ing manifested as a succession of extremely rapid im-4
