Abstract
A vibratory system for changing or maintaining a resultant vibratory force supplied to a spring support conveyor trough has a pair of spaced, parallel shafts and phase elements for supplying a resultant to force to the trough. A sensing device generates a signal corresponding to the real time phase angle between the phase elements. This signal is compared to a signal corresponding to the desired phase angle and the real time phase angle is essentially the same as the desired phase angle thereby providing the desired resultant force to the conveyor.
