A fluid pressurization unit compresses a fluid in response to natural wave action on a body of water such as an ocean. The unit comprises a floating component and a piston assembly. The floating component has sufficient buoyancy to float on water waves and has a compression chamber with an inlet valve biased to receive a fluid at an intake pressure. The piston assembly is slidable within the compression chamber and has a piston shaft and a hollow piston head attached to the piston shaft, which defines a piston reservoir therein with an inlet valve in communication with the compression chamber and biased to receive the fluid at an output pressure, and an outlet for discharging fluid pressurized to at least the output pressure from the pressurization unit. The piston assembly is fixable in place relative to the floating component such that relative movement between the floating component and piston assembly compresses fluid from the intake pressure to at least the output pressure. |

103 | PRESSURE EXCHANGER | PCT/US2005/028356 | 2005-08-10 | WO2006020679A3 | 2006-02-23 | HAUGE, Leif |
A pressure exchanger for transferring pressure energy from a relatively high-pressure fluid stream to another relatively low-pressure fluid stream is provided. A ducted rotor is positioned on a central axle between two end covers inside a pressure vessel with a coaxial inlet and outlet pair that is in communication with a pair of low pressure ports having inclination forming an inlet tangential velocity vector in the direction of rotor rotation and an outlet tangential velocity vector in opposite direction imparting a rotational momentum on rotor. A pair of high-pressure ports is adapted for flow without inclination and imparts no momentum to rotor and flow can be varied without impacting the rotor's RPM. The end covers have a sloped surface following a flat sealing area that increases the clearance in the direction of rotation causing increased outflow during depressurization and lower duct pressure before duct is exposed to low pressure port and furthermore causing increased inflow during the pressurization phase before duct is exposed to the high pressure port, which will dissipate pressure energy as opposed to producing cavitation or pressure waves with result wear and noise. |

105 | METHOD AND APPARATUS FOR FILLING A STORAGE VESSEL WITH COMPRESSED GAS | PCT/US2002/026879 | 2002-08-23 | WO2003019016A1 | 2003-03-06 | KRASNOV, Igor |
A storage vessel (63) is filled with compressed gas (20) by filling a first tank (11) with gas from a low pressure gas source (54). Hydraulic fluid (24) is drawn from a reservoir (47) and pumped into the first tank (11) in contact with the gas (20). This causes the gas (20) in the first tank (11) to flow into the storage vessel (63) as it fills with hydraulic fluid (24). At the same time, gas (20) is supplied from the gas source (54) to a second tank (13). Hydraulic fluid (24) previously introduced into the second tank (13) flows out to the reservoir (47) as the second tank (13) fills with gas (20). When the first tank (11) is full of hydraulic fluid (24), a valve (33) switches the cycle so that the hydraulic pump (39) begins pumping hydraulic fluid (24) back into the second tank (13) while the first tank (11) drains. The cycle is repeated until the storage vessel (63) is filled with gas (20) to a desired pressure. |

108 | Castable three-dimensional stationary phase for electric field-driven applications | US10969134 | 2004-10-19 | US07488407B2 | 2009-02-10 | Timothy J. Shepodd; Leroy Whinnery, Jr.; William R. Even, Jr. |
A polymer material useful as the porous dielectric medium for microfluidic devices generally and electrokinetic pumps in particular. The polymer material is produced from an inverse (water-in-oil) emulsion that creates a 3-dimensional network characterized by small pores and high internal volume, characteristics that are particularly desirable for the dielectric medium for electrokinetic pumps. Further, the material can be cast-to-shape inside a microchannel. The use of bifunctional monomers provides for charge density within the polymer structure sufficient to support electroosmotic flow. The 3-dimensional polymeric material can also be covalently bound to the channel walls thereby making it suitable for high-pressure applications. | ||||||

A pump unit (4) comprises a reservoir (20) for containing a liquid, a duct system (30) for conveying the liquid and a pumping section (50) for subjecting the liquid to a pumping force. Initially, in a pump unit according to the state of the art, the duct system is filled with air. This causes problems at the start of the operation of the pump unit, or, in case the applied pumping force is high enough to prevent such problems, this leads to a flow rate of the liquid that is too high. This problem is solved by bringing about an initial filling of at least a portion of a duct (31) for conveying the liquid from the reservoir (20) to the pumping section (50), under the influence of another force than a pumping force, for example under the influence of gravity. | ||||||

Microfluidic channels utilizing magnetohydrodynamics are used to pump very small volumes of solution. The channels have electrodes along the walls of the channel and a current carrying species within the solution carries the current through the solution. The electric field generated by the use of the current carrying species is perpendicular to a magnetic field applied to the channel. The combination of the electric and magnetic fields causes the solution to flow through the channel. | ||||||

The present invention provides a pump for generating an Electroosmotic Flow (EOF) in a solution in a canal, guide, pipe or equivalent. Electroosmotic flow is generated by application of an electric field through a solution in a canal defined by insulating walls. The phenomenon depends on ionisation of sites on the surface so that for electroneutrality there is an excess mobile charge in the solution. The electric field acts on the excess charge in the solution causing the fluid to flow. The quantity and distribution of excess charge in the solution depends on the solution and the surface materials and is related to a parameter, the zeta (z) potential characterising material/solution combinations. | ||||||

The subject invention is related to a gas injection device with back-flow leaking liquid discharge, comprising a chamber, a gas inlet conduit, a gas outlet conduit, and a liquid discharging conduit, wherein the gas outlet conduit and the liquid discharging conduit are provided with a check valve, respectively. When a gas is passed to the chamber through the gas inlet conduit, the check valve of the gas outlet conduit is open for the gas to be passed into a liquid and the check valve of the liquid discharging conduit is closed. While the gas has stopped injecting into the liquid, the check valve of the gas outlet is closed to prevent the liquid from back flow. The small amount of back-flow leaking liquid accumulated in the chamber can open the check valve of the liquid discharging conduit to discharge the leaking liquid from the chamber. | ||||||

According to the invention, a pumping system comprises at least one pump unit (2) with a vacuum pump casing in which there are multiple pumping stages (5, 6, 7, 8, 9) that includes at least one pumped gas treatment system, characterised by the fact that the pumped gas treatment compromises at least one plasma source (15, 16, 26, 27), located inside the vacuum pump casing of the pump unit (2), to generate a plasma that at least partially decomposes certain gases passing through the pump unit (2). This considerably reduces the size of the pumped gas treatment system and improves its efficiency so that a gas pumping and treatment system can be created that is sufficiently small as to allow it to be placed in close proximity to the process chambers. |
