Title: Apparatus for excluding particle contaminants from a gas lift off mechanical seal
Inventor: GRIFFITH DARYL L
IPC: F04D29/08
Filed: 2015-08-14
Abstract: A particulate exclusion mechanism for a gas lift off seal includes a band fixed to the stationary seal face and extending over the lift off region between the stationary and rotating seal faces, thereby forming an annular cavity surrounding the lift off region that traps barrier gas therein as it leaks through the lift off region and inhibits process fluid from entering the annular cavity and reaching the lift off region. The band can be made of a non-abrasive material such as PTFE or PEEK. The band can extend over the rotating seal face, and a portion of the band can be sufficiently flexible to allow the extended end of the band to constrict in diameter and contact the rotating seal face if the process pressure exceeds the barrier gas pressure. The extended end can include a thicker terminating portion that minimizes clearance with the rotating seal face.

Abstract: A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750° F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.

Abstract: A biocompatible, implantable electrode for electrically active medical devices. The implantable medical electrode has a surface geometry which optimizes the electrical performance of the electrode, while mitigating the undesirable effects associated with prior art porous surfaces. The electrode has an optimized surface topography for improved electrical performance. Such a electrode is suitable for devices which may be permanently implanted in the human body as stimulation electrodes, such as pacemakers, or as sensors of medical conditions. Such is achieved by the application of ultrafast high energy pulses to the surface of a solid, monolithic electrode material for the purpose of increasing the surface area and thereby decreasing its after-potential polarization. In addition, the electrode material comprises a biocompatible metal having a minimal or eliminated amount of metal oxides which are detrimental to electrode performance.

Title: Non-contact flow rate measurement of fluid using surface feature image analysis
Inventor: ZHAO LIANG
IPC: E21B21/08
Filed: 2014-02-19
Abstract: Comparative image analysis is utilized to determine the flow rate of fluids, such as, for example, drilling fluid, completion fluid or hydrocarbons. As fluid flows through a conduit or open trough, a flow rate measurement device illuminates the surface of the fluid. Images of common surface features are then acquired at some time interval. Thereafter, the displacement of the common surface features in the images is analyzed to determine the flow rate of the fluid. Thus, non-contact flow rate measurements of opaque and non-opaque fluids are obtained.
