| 201 | DOUBLE-SCREW LIQUID PUMP | US13885158 | 2010-11-30 | US20130236334A1 | 2013-09-12 | Yan Tang |
| A double-screw liquid pump is provided, which is applicable to an Organic Rankin Cycle (ORC). The double-screw liquid pump includes a semi-sealed or fully sealed shell, and the shell includes a first cavity and a second cavity isolated from each other. A motor is disposed in the first cavity, and a main body part of a double-screw is disposed in the second cavity. At least one rotor of the double-screw is fixedly connected to a rotor of the motor, and the double-screw rotates through driving of the motor. A liquid refrigerant injection inlet and a refrigerant outlet are disposed on the first cavity, and the motor is cooled through evaporation of a liquid refrigerant; a liquid inlet and a liquid outlet are disposed on the second cavity. In the double-screw liquid pump applied to the ORC provided in the present invention, since a resistance torque of the female rotor is very small, the liquid pump does not wear even when the liquid viscosity is very low, contributing to good reliability, and thereby improving power generation efficiency of the ORC. In addition, the semi-sealed or fully sealed shell can effectively prevent leakage of the refrigerant. | ||||||

| A blending pump assembly for accurately maintaining the proper ratio of two fluid components. Flow of a first fluid is utilized to drive a fluid motor, which in turn drives a pumping mechanism to inject a proportional amount of a second fluid into the flow of the first fluid. The fluid motor and pump are sized so that a predetermined ratio between the two fluids is maintained regardless of changes in pressure and flow rate of such first fluid. | ||||||
| 203 | ENHANCEMENT OF SURFACE-ACTIVE SOLID-PHASE HETEROGENEOUS CATALYSTS | US13219293 | 2011-08-26 | US20120197056A1 | 2012-08-02 | Mitchell A. Cotter |
| Surface-active solid-phase catalyst activity may be substantially improved by creating deliberate repetitive surface-to-surface contact between portions of the active surfaces of catalyst objects. While they are immersed in reactant material such contact between portions of the active surfaces of catalyst objects can substantially activate the surfaces of many heterogeneous catalysts. Examples are given of such action employing a multitude of predetermined shapes, supported catalyst structures, etc. agitated or otherwise brought into contact to produce numerous surface collisions. One embodiment employs a gear pump mechanism with catalytically active-surfaced gear teeth to create the repetitive transient contacting action during pumping of a flow of reactant. The invention is applicable to many other forms for creating transient catalytic surface contacting action. Optionally catalytic output of such systems may be significantly further improved by employing radiant energy or vibration. | ||||||

| A pump is formed by a housing (10) having an inlet (11) for connection to a source of fluid and an outlet (12) for pumped fluid. A rotor (15) is rotatable within the housing and the inlet (11) and the outlet (12) are spaced apart around the path of the rotor (15) in the housing. The rotor (15) has surfaces (16a, 16b, 16c, 16d) that form, with the housing (10), closed chambers (18a, 18b, 18c, 18d) which travel around the housing (10) to convey fluid from the inlet (11) to the outlet (12). The housing (10) carries a seal (14) that is located between the inlet (11) and the outlet (12) in the direction of travel of the rotor (15). The seal (14) co-operates with the rotor surfaces (16a, 16b, 16c, 16d) as the surfaces (16a, 16b, 16c, 16d) pass between the outlet (12) and the inlet (11) to prevent the formation of a chamber during said passage and so prevent fluid flow from the outlet (12) to the inlet (11). Such a pump is easily and cheaply produced and is particularly useful in medical applications. | ||||||

| A portable fluid transfer method and apparatus for moving a fluid from a source to a destination.

| 212 | Rotary kinetic tangential pump | US10804709 | 2004-03-22 | US07125224B2 | 2006-10-24 | Charles Dow Raymond |
| A kinetic pump has a tangential axially inner inlet means and a tangential discharge and with a rotor having vanes forming fluid channels to move fluid from inlet to discharge. The volute is eliminated or restricted only to the discharge port sector, and the vanes, hence fluid channels, are oriented so as to be tangent to the inlet port axial cylindrical fluid entry zone. The removal of the volute makes the pump to be positive displacement, since the fluid is contained within the chambers enclosed by vanes, except for when passing the discharge port. The tangential orientation of the vanes allows the fluid, driven by atmospheric pressure to enter the chambers and fill the chambers both by the NPSH and by centrifugal force. The boundaries to the chambers are the fluid passages, and at the axial inner chamber surface by a cylindrical isobar formed by the divergent centrifugal force field, and at the axially outer surface, by an isobar corresponding to the outer distance from the axis at the tangential discharge port. This allows the pump to be filled by NPSH and gain rotational energy from the rotor, resulting in a focused tangential discharge of high velocity. | ||||||

| 214 | Devices Employing Colloidal-Sized Particles | US10711767 | 2004-10-04 | US20050175478A1 | 2005-08-11 | David Marr; Tieying Gong; John Oakey; Alexander Terray |
| The present invention relates to the use colloidal particles to realize photonic and microfluidic devices. In particular embodiments, colloidal particles are used to realize microfluidic a two-way valve, three-way valve, check valve, three-dimensional valve, peristalsis pump, rotary pump, vane pump, and two-lobe gear pump. In certain embodiments, actuation of an active element in the microfluidic structure is accomplished by electrophoresis, the use of an optical trap or “tweezer”, or the application of an electric field or magnetic field. In other embodiments, the application of an electrical field to colloidal particles that are substantially constrained to two dimensional movement is used to realize wave guides, filters and switches for optical signals. | ||||||
| 215 | Metering pump for liquid products | US10258632 | 2000-05-08 | US06857860B1 | 2005-02-22 | Philippe Zimmermann; Joseph Ruegg |
| The invention concerns a metering gear pump comprising a set of gears supported and guided solely by the inner peripheral surface of the lobe of the chamber wherein they are housed. They do not comprise any shaft to act as support or guide, thereby enabling to reduce significantly useless spaced difficult to rinse when changing the product to be pumped. For the same purpose, the driving shaft is flexibly connected to the driving gear. Such arrangement provides the advantage of requiring only one single packing seal. Such a pump, connected to a drive motor and an encoder delivering a signal proportional to the number of pump cycles, enables to provide an accurate metering pump for numerous uses. | ||||||
| 216 | Rotary variable expansible chamber-kinetic hybrid pump | US10279799 | 2002-10-25 | US06824369B2 | 2004-11-30 | Charles Dow Raymond |
| This invention concerns pumping fluids to both high pressures and high flow rates and thus has a very high power density. The technology pertains to both fluid power and to fluid transfer and is adaptable to a wide scope of use. The concept is a very simple rotary variable displacement expansible chamber pump which can also be a rotary kinetic pump and thus is a hybrid. At a positive displacement setting, the pump primes by positive displacement, then as the rotational speed increases; the pump gains a kinetic pumping component, then as head pressure increases the pump again becomes positive displacement. At a zero displacement setting, the pump is purely a rotary kinetic pump. The variable displacement feature allows both performance and efficiency. The porting allows very high rotational speeds and flow rates near to centrifugal designs. When set at zero displacement, the device has features both of positive displacement fan (gear pump) and kinetic (centrifugal pump). The pump is vibration free and silent. Fields of use are fluid power, where the power density is higher, and fluid transfer where high flow rates at higher pressures are required. The concept marries rotary positive displacement to rotary kinetic in pumps. | ||||||
