| 20100086416 | THERMO-PNEUMATIC PERISTALTIC PUMP - A thermo-pneumatic peristaltic pump. A heating base board includes at least one heater. A membrane disposition board is disposed on the heating base board and includes at least one membrane chamber. The membrane chamber includes a first chamber body and a second chamber body. The first chamber body connects to the second chamber body and covers the heater. A fluidic receiving board is disposed on the membrane disposition board and includes at least one fluidic chamber, a fluidic inlet, and a fluidic outlet. The fluidic chamber is connected between the fluidic inlet and the fluidic outlet and is disposed on the second chamber body of the membrane chamber. | 04-08-2010 |

| 20110158827 | Wave Driven Air Compressor - A vertical wave powered air compressor where different parts of the structure are at different depths (and hence static pressures). A plurality of compression stages are stacked one below the other. Each level has two or more chambers. The chambers have a series of check valves or water seals between them. Each passing wave raises and lowers the entire stack. As the stack moves downward, increased water pressure causes water to enter the first chambers at each level compressing the air inside. As the stack returns upward, the decreased water pressure causes water to leave the first chambers allowing the air therein to expand. However, the check valves prevent the air in the second chambers from expanding or escaping back into the first chambers. Another set of check valves allow the air in the second chambers, as it expands, to be forced downward into the next lower first chamber. With each upward and downward movement of the stack, as waves pass, a quantity of air moves downward from stage to stage until, at the bottom, the lowest stage discharges compressed air into a return pipe. The apparatus can be submerged in storms by simply reducing the take off pressure. The compressed air has the temperature of the water and can be used for refrigeration if expanded. | 06-30-2011 |
| 20120114506 | Wave Chamber for a Wave Power Plant, and Method for Producing the Same - The invention concerns a wave chamber for a wave power plant having a water inlet opening situated below the water level and an outlet leading to a ventilation channel, in which an air turbine is installed; whereas the wave chamber contains a free-standing stack of a plurality of chamber segments resting on the bottom of the body of water, which are braced vertically by a large number of traction elements. | 05-10-2012 |

| 20120134851 | COMPRESSOR COMPRISING A PISTON DUMMY - A compressor comprising a liquid acting as piston that is displaceable in the piston compartment is described. | 05-31-2012 |
| 417102000 | Plural chambers | 1 |
| 20100034671 | PISTONLESS COMPRESSOR - The invention relates to a compressor ( | 02-11-2010 |
| 417103000 | Plural chambers | 1 |
| 20080298979 | Engine - An engine having at least one displacer cylinder in which a liquid, in particular an ionic liquid, is arranged and which can be connected to a feed passage and a discharge passage for a medium, is disclosed. The liquid is operatively connected to a displacer device. The displacer cylinder is arranged in a cylindrical drum, rotatably mounted about an axis of rotation, at an angle to the axis of rotation of the cylindrical drum. In an embodiment, the displacer cylinder is arranged perpendicularly to the axis of rotation of the cylindrical drum, and the displacer cylinder is designed as a radial bore arranged in the cylindrical drum. | 12-04-2008 |
