摘要： A hydraulic valve having a body defining an inlet and an outlet. A motor is supported by the body and operates a shaft extending through an interior of the body, the shaft terminating in a gate. A spring is supported within the housing and influences the gate in an open position to permit fluid flow between the inlet and outlet. Upon the occurrence of a pressure differential resulting from a fluid flow through the inlet exceeding a biasing force of the spring, the gate is caused to displace against a valve seat communicating the inlet with the outlet in order to interrupt fluid flow in a standby mode and to define a closed position. The motor operates in a further throttling mode to linearly and incrementally displace the gate between the open and closed positions said outlet and in order to adjust flow through the outlet.

摘要： A motion damping system includes a tank compartmentalized to have a first compartment having a first opening, a second compartment having a second opening, and a third compartment disposed between the first and second compartments. The third compartment is in fluid communication with the first and second openings. A first piston is movably sealed within the first compartment and is in fluid communication with its first opening. A second piston is movably sealed within the second compartment and is in fluid communication with its second opening. A liquid fills the third compartment, a portion of the first compartment up to the first piston, and a portion of the second compartment up to the second piston. A coupling fixedly attached to the first and second pistons moves in correspondence with the first and second pistons. Motion damper(s) coupled to the coupling resist movements of the first and second pistons.

摘要： A method for controlling an inclination of a floating wind turbine platform to optimize power production, or to reduce loads on the turbine, tower, and platform, or both, includes receiving data associated with the inclination of the floating wind turbine platform and wind speed and direction data. An angle of difference between the turbine blade plane and the wind direction is determined, where the angle of difference has a vertical component. A platform ballast system is then caused to distribute ballast to reduce the vertical component to a target angle chosen to optimize power production, or reduce turbine, tower, and platform loads, or both.

摘要： A weight distribution system configured to be integral with a boat or with its structure or hull. The system includes a weight distribution device that translates a cart of weight from one position within a space to another position along a rail. The system is activated by a control that is remote to the system. The system allows for a person to quickly and conveniently alter the weight within the boat to alter, improve or otherwise shape the wake created by the boat.
