摘要

Improvement introduced in the equipment of inversion and of regulation of the amplitude of the oscillations of an installation of sonerºa electrical of bells characterized of a part by the fact of attacking directly by the tree of the electric motor of accionamiento of the oscillations of the bell and by mediation of a special coupling mounted on said shaft the inverter device of the electrical connections automatically ensuring the change of direction of rotation of said motor and to perform on the other hand the combination of the electrostatic drive of the switch that ensures the investment with a regulating member of the amplitude of the oscillations assuring in each one of the directions of march the control of the excitation circuit of said electrodes within the limits of adjustable amplitude by interposition of appropriate means.
