    Abstract: A variable-frequency feeder control using a single oscillator to develop signals for moving materials in either one of two directions. An output signal from the oscillator is applied to a first timing circuit which develops signal pulses for driving a horizontal electromagnetic drive coil. The first timing circuit controls the duration of the signal pulses which determine the amplitude of power to drive the horizontal coil. The output signal from the oscillator is applied to a second timing circuit which developes a phase shifted signal to control the phase between the power applied to the horizontal coil and the power applied to a vertical drive coil. A third timing circuit uses the phase shifted signal to develop signal pulses for driving the vertical coil and controls the duration of the drive pulses.

    Abstract: A vibratory amplitude controller for vibratory mechanisms such as a vibratory feeder having in addition to a parts container, an electromagnetic drive unit operated from an A.C. current source for imparting oscillatory motion to the parts container. The controller includes a sensing means for sampling the electromagnetic drive unit current during a specific predetermined interval each A.C. current cycle to produce a vibratory amplitude representing signal. Means responsive to the vibratory amplitude representing signal controls the amount of power delivered from the A.C. current source to the electromagnetic dive unit to maintain a desired vibratory amplitude under varying load and A.C. line voltage conditions.

    Abstract: A control system is disclosed for use with a device, such as a vibratory bowl feeder, having a bowl or other member mounted for vibratory motion and including an electromagnetic driver for vibratorily driving the part. The control system includes a detector for detecting the vibratory frequency of the part, which tends to vibrate at its resonant frequency, and causes energizing pulses of power to be supplied to the driver supplied at a frequency equal to the detected frequency. Thus, the driving frequency is made equal to the resonant frequency and follows changes in such frequency to obtain maximum performance. The power to the drivers is also switched so that during alternate pulses the current flows through the driver coil in opposite directions to inhibit buildup of residual magnetism in the coil core. The control system uses a phase-locked loop circuit and other parts comprised of components most of which are available as standard integrated circuits. A means for selectively varying the amplitude of member vibration is also included in the control system.

    Abstract: A method of draining parts emerging from hot galvanizing baths using a range of vibration excitation frequencies capable of covering the fundamental frequencies of the parts to be drained. Three different methods are disclosed. According to a first method the vibrations are obtaining by exciting with a narrow band white noise the support for the parts to be drained. According to a second method, the vibrations are produced from a single exciter fed with narrow band white noise and energizing vibrators through the medium of amplifiers. According to a third method, the vibrations are produced by a number of small vibrators each of which furnishes one of the frequencies of the chosen spectrum, whereby said vibrators jointly synthesize the narrow band white noise. Three different means are disclosed for producing vibrations, one where the vibrators are mounted on a false lifting beam, the second where the vibrators are mounted on the lifting beam, and the third where the vibrators are enclosed in a container placed between the lifting beam and the hoisting means.
