Abstract: A system and method for electrically controlling a submersible hydro-electric production system for avoiding leakage of oil and contaminants used in the existing hydraulic systems. The system comprises one or more submersible electrical actuators operably connected to a gate operating ring which in turn is connected to a plurality of wicket gates in the turbine. Each submersible electrical actuator comprises an electrical motor connected to a push-pull rod which is configured to transform the rotation movement received at a first end thereof to a linear movement at a telescoping end opposite the first end for rotating the gate operating ring to a desired position. The electrical actuator includes a waterproof structure which houses the electrical motor and the push-pull rod and at the same time allows for a telescoping movement of the push-pull rod for rotating the gate operating ring.

Abstract: System and method for controlling operation of a hydroelectric production system comprising electrical actuators operably connected at opposite positions of a gate operating ring for rotating the wicket gates to a desired position. The system receives a single control signal designed for a hydraulic system comprising hydraulic actuators operably connected to a single fluid reservoir and configured to work in tandem to produce simultaneous and opposite axial movements. The system comprises a control interface adapted to produce new control signals, each new signal being intended to a different electrical actuator to cause the electrical actuators to have axial movements which are identical in speed and in opposite directions to substantially imitate the exact movement of the hydraulic actuators onto the gate operating ring. The system is configured to introduce a dampening effect to reduce sudden acceleration and deceleration which is purposely used in hydraulic systems to overcome friction and static effects.

Abstract: The invention pertains in general to a latching mechanism for maintaining desired friction levels on an optical disc in an optical disc restoration device. In particular the invention pertains to devices, systems and methods for easily maintaining friction levels between pads and an optical disc in an optical disc restoration device for ease of adjusting friction settings during quality control, repair operation or when optimization settings are being set in an optical disc restoration device by a user.
