    摘要： A solid state switching circuit for an electromagnetic pump is disclosed herein. The circuit comprises a Darlington amplifier controlling the current flow through the pump's solenoid in response to the state of a piston position sensitive electrical switch, a Zener diode and capacitance in the base circuit of the Darlington amplifier in parallel with the electrical switch and an inductive clamp circuit in parallel with the pump's solenoid coil.

    摘要： A variable frequency electrical power supply circuit includes a power circuit that provides a drive signal to energize a load and a control circuit that controls application of the drive signal to the load. The load may be an electro-magnetic or electromechanical device, such as a solenoid to provide in response to the drive signal a motive force to a mechanical apparatus for causing resonant vibratory motion therein. The power supply circuit may be self tuning to the resonant frequency of the mechanical apparatus or may be manually tunable.

    摘要： A vibrator comprises a vibratory unit composed of resilient sheet material and having two main vibratory arms disposed in spaced parallel relationship and interconnected at their ends by two connecting end portions. A pair of central vibratory arms extend inwardly from each connecting end portion in a direction towards each other and the central arms and the main arms all lie in a common plane. The vibratory system comprises the vibrator in combination with a driving magnet connected to one of the central arms thereof and a driving coil coacting with the driving magnet to alternately drive same to effect flexural vibration of the central arm accompanied by vibration of the main vibratory arms. A driven magnet is connected to either the same central arm or the other central arm of the vibrator and coacts with a magnetic follower wheel to rotationally drive the follower wheel in an intermittent manner in accordance with the vibratory motion of the main vibratory arms.
