| 154 | PROCESS FOR THE PRODUCTION OF HYDRAULIC ENERGY AND PRODUCTION OF POTABLE WATER BY DIRECT OSMOSIS | US13681740 | 2012-11-20 | US20130160435A1 | 2013-06-27 | Antonio ORDONEZ FERNANDEZ |
| The present invention relates to a process for the production of hydraulic energy by direct osmosis from two saline solutions having different concentrations made to pass through one or more modules of semipermeable membranes having a double inlet and outlet port, originally designed to execute the process of inverse osmosis, without a requirement to realise any technical modification to said modules of membranes. In this manner, an osmotic potential is produced in the membranes creating a current of solution having a pressure sufficient to produce hydraulic energy. A further object of the present invention is the installation designed to produce hydraulic energy according to the stated procedure and the use thereof, together with a desalination plant and a tertiary waste water treatment plant comprising the installation to produce hydraulic energy. | ||||||

| 160 | Fluid Linkage for Mechanical Linkage Replacement and Servocontrol | US11306469 | 2005-12-29 | US20070163259A1 | 2007-07-19 | Timothy Webster |
| A fluid linkage allows for coordinated movement of mechanical components separated by a distance. In applications where accurate coordination is required, a mechanism called a limit-switch valve (180) is activated at specific actuator positions. The limit-switch valves are able to detect fluid loss in the fluid linkage between the actuators and compensate for this fluid loss. A volume displacement servomechanism is created by connecting pressure actuators (360, 361) of a fluid control valve (120) to a control actuator (133). A basic position feedback servomechanism is created by connecting pressure actuators (362, 363) of a fluid control valve (150) to a control actuator (135) and a feedback actuator (145). The fluid control valve (150) controls the servomotor actuator (146) to which the feedback actuator (145) is attached. A position tactile feedback servomechanism allows an operator to perceive the load on the servomotor actuator (146) by its reflection on the control actuator (135). This tactile feedback is created by connecting tactile feedback actuators (364, 365) to the fluid servomotor (146). Accurate servo action is achieved through the use of limit-switch valves. The fluid linkage and limit-switch valve are extremely useful in self-leveling, steering linkage replacement, aerodynamic control surface servomechanisms, and many more applications. | ||||||
