Title: Method and apparatus for extending flow range of a downhole turbine
Inventor: MORIARTY KEITH
IPC: E21B4/02
Filed: 2007-02-16
Granted: 2012-08-28
Abstract: The present invention provides means to extend the flow rate range over which a downhole turbine 70 will return a power output sufficient to meet the minimum downhole power requirements. In one embodiment, the present invention relates to an arrangement of axial vanes 77 that are situated such that the rotation of the rotor 76 generates an increasing drag force, thereby extending the upper limit of the flow rate range. In another embodiment, the present invention relates to an arrangement of restriction assemblies 75 that can be used to maximize the fluid velocity relative to the fluid flow rate past the stator 74 to achieve the necessary speed and power to rotate rotor 76, thereby extending the lower limit of the flow rate range. In another embodiment, the axial vanes 77 and restriction assemblies 75 are used in combination to further extend both the upper and lower limits of the flow rate range of the downhole turbine 70.

Abstract: A system and method is provided for quickly tracking a physical phenomena represented within the three-dimensional volume data set. A plurality of planes may be successively displayed in the three-dimensional volume data set from which points are digitized related to the structure of interest to create a spline curve on each plane. The area between the spline curves (1914, 1916, 1918, 1920) is interpolated to produce a surface (1912) representative of the structure of interest, which may for example be a fault plane described by the three-dimensional volume data set. In this manner, the user can more easily and effectively visualize and interpret the features and physical parameters that are inherent in the three-dimensional volume data set.

Title: Measurement of wheel and/or axle load of road vehicles
Inventor: BERGAN TERRANCE ARTHUR
IPC: G01G3/14
Filed: 2008-11-25
Granted: 2013-02-26
Abstract: The present invention provides an improved weigh-in-motion scale. A slight increase in the thickness of a an upper, flexibly-deformable metal plate in a thin, flexibly-deformable plate system coupled with a change in the transverse locations of the load cells provides the improved weigh-in-motion scale, which is capable of weighing substantially heavier loads than previously known weigh-in-motion scales. In use, as weight is applied to the weigh-in-motion scale, the upper flexibly-deformable metal plate elastically bends. The strain gauges thus provide a changing resistive value proportional to the bending of the flexible element and the weight applied, to generate signals to the Wheatstone bridge circuit, which then provides output signals from the Wheatstone bridge circuit, which are proportional to the force applied to the upper flexibly-deformable metal plate.
