Abstract
23,049. Bosch, R., [Firm of]. June 2, [Convention date]. Current detector.-The existence of a current in the ignition circuit of an internal-combustion engine is indicated by an electro-magnetic buzzer in series with the ignition coil B. The armature O of the buzzer, when attracted by the magnet c, short-circuits the magnet winding, so that the coil circuit is not opened by the action of the buzzer.
