Title: Circuit for controlling damp shock loading

Abstract: This is concerned with an electric circuit for controlling or damping the shock loading on the structural components and parts of machinery which are moved by a conventional hydraulic cylinder. It is more specifically concerned with a control circuit to be used with a proportional control valve so that the mass moved by the cylinder will be gradually accelerated and decelerated to avoid abrupt starts and stops.
