  • Precision servo control system for a pneumatic actuator
    Patent number: 6705199
    Abstract: A precision servo control system for a pneumatic actuator has a piston positionable over a stroke of the pneumatic actuator using a supply of pressurized gas. A brake and a sensor system are connected to the actuator and to the servo control system. The servo control system operates to initiate the forward thrust from the pressurized gas to move the piston along the stroke. When a braking point along the stroke is determined, the servo control system initiates a reverse thrust from the pressurized gas while maintaining the forward thrust and simultaneously begins to selectively apply the brake to stop the piston within a predetermined tolerance of a desired stopping position.

When a braking point along the stroke is determined, the servo control system initiates a reverse thrust from the pressurized gas while maintaining the forward thrust and simultaneously begins to selectively apply the brake to stop the piston within a predetermined tolerance of a desired stopping position. The precision servo control system is easily programmable in a manner similar to that of a control system for electrical actuators. The precision servo control system can maintain the predetermined tolerance even under changing loads, long stroke lengths or vertically oriented stroke directions.

  • Stabilizer for ball screw actuator
    Patent number: 6418807
    Abstract: A stabilizer for a ball screw actuator of the type having a housing, and externally threaded lead screw and a drive nut movable along the lead screw in which the stabilizer includes a first member rotationally fixed but movable linearly relative to the cylinder housing and a second member rotatable relative to, but linearly fixed, relative to the first member.
