| 20110106548 | COMPENSATION DISCRIMINATION DETECTOR - One embodiment of the invention includes a computer-implemented method for detecting compensation discrimination. The method includes determining compensation for an employee in a protected class, and determining median compensation for all comparable employees to the employee in the protected class. The method may then further include analyzing the compensation and the median compensation to determine whether there is a compensation differential that demonstrates discrimination in the compensation for the employee in the protected class. | 05-05-2011 |

| 20100278671 | METHOD AND APPARATUS FOR REDUCING PARTICLES IN A SCREW PUMP LUBRICANT - A screw pump system has a plurality of rotors disposed inside a pump casing. Each rotor comprises a shaft and a set of threads disposed on the shaft configured to mesh with at least one other set of threads. A plurality of bearings are coupled to each end of each of the rotors. A plurality of gears are coupled to an end of each of the rotors. The gears are configured to reduce a size of particulates in a lubrication fluid by flowing the particulates through the rotating gears. The gears may serve as timing gears for the rotors as well as perform pumping of the lubrication fluid. | 11-04-2010 |
| 20100278672 | METHOD AND APPARATUS FOR LUBRICATING A SCREW PUMP SYSTEM - A pump system includes inlet chambers, an outlet chamber, and rotors disposed inside the inlet chambers and the outlet chamber to pump a process fluid from the inlet chambers to the outlet chamber and to direct the process fluid to a separator. A gear chamber is configured to receive a portion of the process fluid from the separator. First and second sets of pump bearings are coupled to the rotors and lubricated by the portion of the process fluid flowing from the gear chamber. A conduit is configured to direct the portion of the process fluid from the pump bearings back to the gear chamber. Some of the portion of the process fluid lubricating the pump bearings is permitted to leak to the inlet chambers. Additional process fluid is continually added to the portion of the process fluid to compensate for fluid leaking to the inlet chambers. | 11-04-2010 |
| 20100278673 | METHOD AND APPARATUS FOR MANAGING FLUID FLOW WITHIN A SCREW PUMP SYSTEM - In a pump system, a process fluid is directed into inlet chambers of a pump casing at an inlet pressure, and a plurality of rotors disposed inside the pump casing are rotated to pump the process fluid from the inlet chambers to an outlet chamber located between the inlet chambers, wherein the process fluid in the outlet chambers is at an outlet pressure. The process fluid is directed from the outlet chamber to a separator configured to separate particulate matter from the process fluid, and a portion of separated process fluid is directed from the separator to a gear chamber of the pump. Pump bearings are lubricated with the portion of separated process fluid from the gear chamber. Some of the portion of the separated process fluid from the pump bearing is leaked to the inlet chambers via rotor shrouds to reduce accumulation of particulate matter in the inlet chambers. | 11-04-2010 |
| 20110103987 | PUMP SYSTEM - The present invention provides a pump system comprising a bearing housing coupled to a pump liner, the pump liner defining a fluid conduit, the pump liner comprising a fluid inlet and a fluid outlet; and at least one rotor having a first rotor portion and a second rotor portion, the first rotor portion being disposed within the fluid conduit and the second rotor portion being disposed within the bearing housing; the first rotor portion comprising a first conveying stage adjacent to the bearing housing, and a second conveying stage adjacent to the first conveying stage, the first and second conveying stages being configured to convey a fluid, the first conveying stage being configured to convey the fluid from the bearing housing into the fluid conduit. The new pump systems rely on a dynamic restriction to reduce the need for mechanical seals between bearing housings and raw process fluid. | 05-05-2011 |

| 20080309019 | SEALING ASSEMBLY FOR ROTARY MACHINES - A sealing assembly is provided. The sealing assembly includes a foil disposed circumferentially around a rotating component and configured to provide primary sealing to the rotating component between high pressure and low pressure sides and a spring system disposed adjacent to the foil. The spring system includes a plurality of features to facilitate foil surface to follow excursions of the rotating component, wherein the plurality of features provide secondary sealing from the high pressure to the low pressure sides between the foil and a stationary component. | 12-18-2008 |
| 20090098003 | MULTIPHASE SCREW PUMP - A twin screw pump includes a pair of rotors disposed inside a casing having an inlet and an outlet. Each rotor includes a set of threads disposed on a portion of an outer surface of a shaft. A first bearing is coupled at a first end of the shaft and a second bearing is coupled at a second end of the shaft. The first and second bearings are not separated by one or more seals. The first and second bearings are configured for being lubricated by the liquid medium of the process fluid when the twin screw pump is in an operational mode. | 04-16-2009 |

| 20090039257 | Electron beam device - An electron beam device has an electron gun for generating an electron beam, an objective lens for focusing the electron beam on an object and at least one detector for detecting electrons emitted by the object or electrons backscattered by the object. Detection of electrons emitted by or backscattered by an object may be simplified and improved using quadrupole devices and certain configurations of these devices provided in the electron beam device. | 02-12-2009 |
| 20090309024 | Electron-beam device and detector system - An electron-beam device having a beam generator for generating an electron beam, an objective lens for focusing the electron beam on an object, and at least one detector for detecting electrons scattered on the object or emitted by the object. Furthermore, a detector system for detecting electrons is described. With an electron-beam device having a detector system according to the present invention, it is possible to make a selection in a simple manner, in particular according to backscattered and secondary electrons. At the same time, as many electrons as possible may be detected using the detector system. For this purpose, the electron-beam device exhibits at least one adjustable diaphragm which is allocated to the detector. The detector system exhibits a detector on which a reflector for reflecting electrons onto the detector is accommodated. | 12-17-2009 |
