| 20100070178 | METHOD AND SYSTEM FOR VEHICLE ORIENTATION MEASUREMENT - The orientation of a self-propelled vehicle or a towed vehicle relative to the direction of travel of the vehicle can be determined by mounting two ground speed sensors on the vehicle. The orientation of the vehicle relative to the direction of travel of the vehicle can be used to correct the error in the location of an implement mounted on the vehicle determined by a GPS system mounted on the vehicle or the vehicle towing the implement due to crabbing of the vehicle as the vehicle travels substantially perpendicular to a significant slope. | 03-18-2010 |

| 20090098001 | SEALING TABS ON ORBITING SCROLL - An improved sealing mechanism for a positive fluid displacement apparatus, where sealing tabs are located on the orbiting scroll. The sealing tabs can be integrally formed with the orbiting scroll or disposed on a piston that is mounted on the orbiting scroll. | 04-16-2009 |
| 20100111740 | SCROLL-TYPE FLUID DISPLACEMENT APPARATUS WITH IMPROVED COOLING SYSTEM - An axial air cooling system for scroll-type positive fluid displacement apparatus provides needed cooling. The system includes an axial fan and centrifugal pump and internal cooling air channels inside parts integrating main housing, base housing and motor housing with their corresponding shell parts by cooling fins. The cooling air channel also includes passages inside the orbiting scroll, shaft central hole and gaps inside stator slots and winding. Heat pipes are installed inside the fixed and orbiting scrolls to conduct heat from inside of the apparatus to the peripheral condenser portion of the heat pipes to be cooled by the cooling air. | 05-06-2010 |
| 20100196183 | SCROLL COMPRESSOR WITH MATERIALS TO ALLOW RUN-IN - A scroll compressor comprises a non-orbiting scroll member having a base and a generally spiral wrap extending from its base, and an orbiting scroll member having a base and a generally spiral wrap extending from its base. The wraps of the non-orbiting and orbiting scroll members interfit to define compression chambers. A drive shaft causes the orbiting scroll member to orbit relative to the non-orbiting scroll member. At least one of the non-orbiting and orbiting scroll operate to move in an axial direction toward the other of the non-orbiting and orbiting scroll members. The scroll compressor supplies a bias force to bias the at least one scroll member toward the other. A first of the non-orbiting and orbiting scroll members have at least a portion of its surface formed of a material that is harder than the material that it will contact on a second of the non-orbiting and orbiting scroll members, such that upon start-up there will be run-in and removal of the material. | 08-05-2010 |
| 20100196184 | SCROLL COMPRESSOR WITH BACK PRESSURE POCKET RECEIVING DISCHARGE PRESSURE FLUID - A face of a base of an orbiting scroll member is aligned with a thrust bearing. The thrust bearing includes a back pressure pocket and a seal for sealing the back pressure pocket to entrap a compressed fluid. There is a tap for tapping fluid at a discharge pressure into said back pressure pocket. | 08-05-2010 |
| 20100202911 | SCROLL-TYPE POSITIVE DISPLACEMENT APPARATUS WITH PLASTIC SCROLLS - At least one of the scroll members is composed of a metallic insert having substantial the same configuration of the scroll member, i.e. an end plate and spiral wraps fixed to and extended from the end plate. The metallic insert has anchor holes and connecting holes for bonding the plastic coating layer on to the metallic insert. The anchor holes also serve as gas escaping passages during injection molding process. The mold has multiple poring gates to minimize the pressure gradients across the spiral wraps during the injection molding process. The metallic insert has also tubers sticking out from the tip of its spiral wraps. The tubers are firmly held by the mold in the injection molding process to prevent movement of the spiral wraps under the pressure from the injected plastic flow. The metallic inserts can be fully or partially coated by the plastic compound such that there is no metallic to metallic contact between the scroll members during operations. | 08-12-2010 |

| 20100158739 | GEAR PUMP WITH SLOTS IN TEETH TO REDUCE CAVITATION - A gear pump comprises a drive gear being mounted for rotation about a first axis and having a plurality of gear teeth at a radially outer location. A driven gear is mounted for rotation about a second axis, and having a plurality of teeth at a radially outer location. The drive gear teeth engage the driven gear teeth at a contact face to cause the driven gear to rotate. Slots are formed in the contact face of one of the drive and driven gear teeth. | 06-24-2010 |

| 20080251006 | Controlled synthesis of nanoparticles using continuous liquid-flow aerosol method - A method and apparatus for producing surface stabilized nanometer-sized particles, the method including the steps of forming the aerosol by mixing reactants, a surface-stabilizing surfactant, and a liquid to form a mixture, forming a mist of droplets of the mixture, heating the droplets to cause a reaction between species of the mixture and collecting the nanometer-sized products. The method for producing various size, shape and size distribution of nanoparticles by changing the ratio of the reagents and the ligands in the mixture of precursors. | 10-16-2008 |
| 20100028249 | Controlled synthesis of nanoparticles using continuous liquid-flow aerosol method - A method and apparatus for producing surface stabilized nanometer-sized particles includes the steps of mixing reactants, a surface-stabilizing surfactant, and a high boiling point liquid to form a mixture, continuously passing the mixture through an ultrasonic spray nozzle to form a mist of droplets of the mixture, injecting the mist directly into a furnace to cause a reaction between species of the mixture, and collecting the nanometer-sized products. The ultrasonic nozzle is positioned directly at one end of the heating furnace, preferably the top end, for travel of the droplets through the furnace. The continuous liquid-flow process, along with certain operating parameters, eliminates the need for dilution of the high boiling point liquid with a low boiling point solvent as in the prior art, significantly increases the yield, improves the quality of the product, and makes the process scalable. | 02-04-2010 |
