Abstract: The present invention concerns the down hole motors used in the oil prospecting industry to drive drill bits for drilling the ground at great depths. The down hole motor (1) comprises a drive shaft (5) held in the motor body (3) by an axial thrust bearing (6) and by a radial bearing (7). The radial bearing (7) is a tubular member whose interior surface is coated with an anti-abrasion layer (11) formed by laser-assisted facing directly inside an alloy steel radial bearing body (10). The thickness of the facing layer is then reduced by removing material by means of a cutting tool. This produces a radial bearing (7) that is relatively insensitive to drilling mud and confers great reliability on the down hole motor (1).

Inventor: BRANDENBURGER LARRY B
IPC: C08G63/78
Filed: 2008-02-06
Abstract: Medium and high molecular weight polyester polymers are prepared in syrup form from an ester oligomer. The oligomer is converted to the polymer by polycondensation at atmospheric pressure and elevated temperature in a nonreactive carrier capable of forming an azeotrope with water. The ester oligomerization or polycondensation reactions desirably are monitored using a non-viscometric technique. The process has a rapid cycle time. The syrup contains the polymer and nonreactive carrier, and may more conveniently be used to make initially non-solid products such as polyester coatings than is the case when employing pelletized solid polyester resins.

Inventor: ROGERS PHILLIP L
IPC: G01P3/36
Filed: 2008-04-30
Abstract: A laser Doppler velocimeter is formed using a fiber laser as the lasing medium. Within the velocimeter, all optical signals, transmitted and received, are conveyed by optical fibers. An amplifier amplifies a source laser, which is then transmitted to one or more transceivers. The one or more transceivers, each projecting along a different axis, and each with a single optical fiber input/output interface act as both the transmission device to focus the radiation at a target region, and as the receiving system for collecting reflected radiation. The transceivers each include an amplifier to further amplify the radiation received from the laser source. The one or more transceivers transmit radiation simultaneously to the target region, and may be located remotely from the laser source. The portion of the reflected radiation collected by the receiving system is analyzed to determine the Doppler shift caused by targets at the focal point of the one or more transceivers.

Abstract: In certain embodiments, a method for monitoring, alerting and remedia-tion of systems is provided. The method pro-vides for receiving data from one or more data sources and logging the data. A first metadata fingerprint is created for a particular data source. The first metadata fingerprint is indicative of a first quantity of data output for the particular data source. A second metadata fingerprint is created for the same data source. The second metadata fingerprint is in-dicative of a second quantity of data output for the data source. The second metadata fin-fingerprint is created from data received at a dif-ferent point in time from the first metadata fingerprint. The first metadata fingerprint is compared with the second metadata fingerprint associated with the particular data source. An alert is generated when the com-parison indicates that the first metadata fin-fingerprint does not correspond within a speci-fied tolerance to the second metadata finger-print.
