Apparatuses For Generation Of Mechanical Vibrations
(AREA)
Abstract
Improvements in electric clocks, characterized essentially by the fact of comprising a vibrating rod with an adjustable counterweight at its free end, constituted by a nut, which moves at said end to allow, at will, the variation of the oscillations, including the rod, fixed and transverse to it a magnet bar, which is introduced by its ends in two coils, in one of which, when the magnet moves, a very small electromotive force is induced directed to a transistor, which acts on a battery electrical, emitting this one impulse of current to the other coil, acting of motor coil, on the magnet, keeping the oscillations at a constant frequency.
