123 Microfluidic pump driven by thermoacoustic effect US10726670 2003-12-04 US20050047924A1 2005-03-03 Ya-Wen Chou; Meen-Dau Hoo; Chih-Chieh Lin
A microfluidic pump driven by thermoacoustic effect is mainly composed of a thermoacoustic device, a fluid-storing tank, and at least one microchannel, etc., wherein the thermoacoustic device may convert thermal energy into acoustic energy. Pressure fluctuation and velocity fluctuation with high frequency are generated by the acoustic wave. According to the high amplitude pressure fluctuation, the microfluid with high moving velocity emitted through microchannels. Since there is no movable part arranged in the thermo-acoustic generator. In the meantime, it indirectly drives the working fluid located in the fluid-storing tank by the manner of indirect contact. So the present invention may be applied in the non-conductive fluid so as to greatly extend its field of application. Moreover, the characteristics of the fluid won't be influenced by the heating process as well. The present invention is indeed a microfluid-driving device that has inventiveness and high application value.
124 Optical interference display panel and manufacturing method thereof US10807128 2004-03-24 US20050042117A1 2005-02-24 Wen-Jian Lin
A first electrode and a sacrificial layer are sequentially formed on a substrate, and then first openings for forming supports inside are formed in the first electrode and the sacrificial layer. The supports are formed in the first openings, and then a second electrode is formed on the sacrificial layer and the supports, thus forming a micro electro mechanical system structure. Afterward, an adhesive is used to adhere and fix a protection structure to the substrate for forming a chamber to enclose the micro electro mechanical system structure, and at least one second opening is preserved on sidewalls of the chamber. A release etch process is subsequently employed to remove the sacrificial layer through the second opening in order to form cavities in an optical interference reflection structure. Finally, the second opening is closed to seal the optical interference reflection structure between the substrate and the protection structure.

127 Method for improving the performance of electrokinetic micropumps US10891527 2004-07-14 US20050002795A1 2005-01-06 Brian Kirby
A method for improving the pumping performance of an electrokinetic pump. The addition of zwitterions to the pump fluid or electrolyte of an electrokinetic pump (EKP) has been found to improve the pumping performance by increasing the maximum pressure and flow rate generated and increasing the efficiency for a given applied voltage. Zwitterions comprise a class of molecules that contain separated positive and negative charge centers within the molecule, are substantially electrically neutral, and generally exhibit a large inherent dipole moment (≈20-25 D) as a consequence of charge separation within the structure of the molecule. The addition of the zwitterion trimethyl ammonium propane sulfonate to an EKP electrolyte has resulted in a 3-fold increase in pump efficiency and a 2.5-fold increase in generated pressure for a given applied voltage.

131 Electrochemically driven heat pump US703865 1985-02-21 US4593534A 1986-06-10 David P. Bloomfield
A refrigeration cycle or heat pump employing an electrochemical compressor. The cycle uses a working fluid at least one component of which is electrochemically active. Another component of the working fluid is condensable. In one embodiment, the electrochemically active component is hydrogen and the condensable component is water. The electrochemical compressor raises the pressure of the working fluid and delivers it to a condenser where the condensable component is precipitated by heat exchange with a sink fluid. The working fluid is then reduced in pressure in a thermal expansion valve. Subsequently, the low pressure working fluid is delivered to an evaporator where the condensed phase of the working fluid is boiled by heat exchange with a source fluid. The evaporator effluent working fluid may be partially in the gas phase and partially in the liquid phase when it is returned from the evaporator to the electrochemical compressor. In the process, heat energy is transported from the evaporator to the condenser and consequently, from the heat source at low temperature to the heat sink at high temperature.

133 Water displacement mercury pump US602243 1984-04-20 US4534709A 1985-08-13 Marshall G. Nielsen
A water displacement mercury pump has a fluid inlet conduit and diffuser, a valve, a pressure cannister, and a fluid outlet conduit. The valve has a valve head which seats in an opening in the cannister. The entire assembly is readily insertable into a process vessel which produces mercury as a product. As the mercury settles, it flows into the opening in the cannister displacing lighter material. When the valve is in a closed position, the pressure cannister is sealed except for the fluid inlet conduit and the fluid outlet conduit. Introduction of a lighter fluid into the cannister will act to displace a heavier fluid from the cannister via the fluid outlet conduit. The entire pump assembly penetrates only a top wall of the process vessel, and not the sides or the bottom wall of the process vessel. This insures a leak-proof environment and is especially suitable for processing of hazardous materials.

135 Gas compression system US121666 1980-02-15 US4311025A 1982-01-19 Warren Rice
A multiple disk compressor has a through flow of a two-phase medium consisting of gas bubbles entrained in a non-miscible liquid carrier and causes an almost isothermal compression of the gaseous phase of the medium. Because of the larger density at a given tip speed, much higher pressure ratio is obtained in a single stage than can be obtained in a conventional compressor having a throughflow of gas only. The liquid carrier, after separation from the compressed gaseous medium, provides heat to a heat exchanger before being reduced in pressure and returned to the compressor. The separated gaseous medium under pressure is withdrawn as the useful product. Where the compressor is a part of a refrigeration system and the gaseous medium is a refrigerant, the compressed gaseous medium, which is transformed to a liquid state by the compressor, flows through an expansion valve to reduce its pressure and temperature, an evaporator to cool a medium, such as air, and is returned to the compressor for re-entrainment in the liquid carrier.

140 Hydrogas lift system US32502873 1973-01-19 US3814545A 1974-06-04 WATERS W
A power fluid is pumped downwardly through a power fluid tube toward the bottom of a well. The power fluid, due to pressure placed on the power oil fluid by a surface pump, forces the production fluid through a check valve and upwardly through a production fluid tube to the surface of the wall. Compressed gas is used to withdraw the power fluid from the power fluid tube so that the production fluid may again rise to the level of the production fluid tube and the pumping cycle is thereafter repeated. The power oil may also be removed by swabbing, rod pump, rotary pump, or any other form of artificial lift which may be applicable to the well.
