| 20090000288 | SYSTEM AND METHOD FOR CONVERTING KINETIC ENERGY FROM BROWNIAN MOTION OF GASES OR LIQUIDS TO USEFUL ENERGY, FORCE AND WORK - A system for producing energy includes a solvent chamber, a pressure chamber and a semi-permeable barrier separating the solvent chamber from the pressure chamber. The solvent chamber for holds a solvent, and the pressure chamber hold a solute solution comprising a solute dissolved in a solvent. The semi-permeable barrier is permeable to solvent molecules and impermeable to solute molecules. Solvent molecules effuse across the semi-permeable barrier into the solute solution of the closed pressure chamber to increase the pressure of the pressure chamber, thereby generating energy in the form of hydrostatic pressure. A conversion device may convert the increased pressure in the pressure chamber to energy. The solute solution may be expelled and recycled after use. | 01-01-2009 |
| 20090007555 | Biomimetic Water Membrane Comprising Aquaporins Used in the Production of Salinity Power - The present invention relates to the use of aquaporin containing membranes in the production of salinity power. The membranes are preferably lipid bilayers incorporating reconstituted aquaporin channels, e.g. entrapped between porous support materials, or alternatively enclosing a highly hydrophobic porous support material. Also disclosed is a salinity power plant. | 01-08-2009 |
| 20110296821 | IMPROVING EFFICIENCY OF LIQUID HEAT EXCHANGE IN COMPRESSED-GAS ENERGY STORAGE SYSTEMS - In various embodiments, efficiency of energy storage and recovery systems employing compressed air and liquid heat exchange is improved via control of the system operation and/or the properties of the heat-exchange liquid. | 12-08-2011 |
| 20140047823 | MICROACTUATOR USING BUBBLE GROWTH AND DESTRUCTION - Disclosed is a microactuator using growth and destruction of bubbles including a first chamber provided with a heating plate installed at an exterior of a bottom surface of the first chamber to generate heat, and filled with a first liquid working fluid such that bubbles are caused, by heat, to grow at an interface of a cavity on an inner surface of the first chamber to be heated, a second chamber provided with a heating plate installed at an exterior of a bottom surface of the second chamber to generate heat, and filled with a second liquid working fluid such that bubbles are caused, by heat, to grow at an interface of a cavity on an inner surface of the second chamber to be heated, a connection path to connect the first chamber and the second chamber to each other, the connection path being provided therein with a moving member adapted to isolate the first and second chambers from each other and to move when internal pressure changes according to growth and destruction of the bubbles, a first subline to connect the connection path to the second chamber such that the first working fluid moves the moving member to one side and is guided to the second chamber according to increase in the internal pressure by growth of the bubbles in the first chamber, a second subline to connect the connection path to the first chamber such that the second working fluid moves the moving member to the other side and is guided to the first chamber according to increase in internal pressure by growth of the bubbles in the second chamber, and a plurality of cooling means installed on the first subline and the second subline to destroy bubbles produced in the first and second chambers. | 02-20-2014 |
| 20150082778 | Balanced actuating device for lifting and/or transport apparatus and apparatus comprising the device - A balanced actuating device includes a supporting frame having a support for a load, a guide guiding the support along a drive direction, and a drive moving the support along the guide for a predetermined stroke between a first and a second end position. The drive includes a cylindrical jacket enclosing a first working chamber and housing a drive cylinder exerting a drive force on the support, a compensation cylinder placed externally to the drive cylinder and exerting thereon a compensation force sufficient to balance the external load, and a first supply station of the first chamber ( | 03-26-2015 |
| 20150330261 | Waste Heat Recovery Systems Having Magnetic Liquid Seals - A system including a seal cartridge is provided. The seal cartridge includes a housing defining a passageway that receives a driveshaft. A dry gas seal is circumferentially disposed about the passageway within the housing at a first axial location along the housing. A magnetic liquid seal is circumferentially disposed about the passageway within the housing at a second axial location along the housing. A fluid leakage cavity is formed between the dry gas seal at the first axial location and the magnetic liquid seal at the second axial location. An extraction port is disposed in the housing and enables recovery of a leaked fluid from the fluid leakage cavity. | 11-19-2015 |
| 20150345519 | Magnetohydrodynamic actuator - The present invention is for an apparatus and method for an actuator using an magnetohydrodynamic (MHD) pump to electrically generate a hydraulic pressure and a flow in a liquid metal, thereby causing the liquid metal to act on and extend an expansion member such as extend bellows, membrane, rolling diaphragm, or a piston in a cylinder. The resulting mechanical displacement of the expansion member may be beneficially used to exert a force, pressure, and/or to move elements of a machine. In particular, mechanical displacement (stroke) of the actuator may actuate elements of a humanoid robot, or artificial limb prosthetic, or flight control surfaces of an aircraft. The actuator may be arranged to operate bi-directionally by reversing the polarity of the electric current supplied to the MHD pump. Force exerted by the MHD actuator may be controlled by varying the electric current of the MHD pump drive current. | 12-03-2015 |
