Patent CA-2321225-A1 (CA)
Inventor: FLAKS JASON S
IPC: G10L21/0208
Filed: 2000-09-27
Abstract: A method and apparatus for the real-time creation of an output audio signal from an input signal with an unwanted or noise portion. The system detects the unwanted portion of the input signal by utilizing an adaptive detection filter and reduces the unwanted portion of the input signal. The reduction of the unwanted portion is performed by compression of the unwanted signal, subtraction of the unwanted portion of the signal, or eliminating the output signal until the unwanted portion is no longer detected. The system is specifically designed to find a high frequency and high amplitude sound such as a sibilant.

Filed: 1999-03-03
Abstract: An MWD method and apparatus for determining parameters of interest in a formation has a sensor assembly mounted on a slidable sleeve slidably coupled to a longitudinal member, such as a section of drill pipe. When the sensor assembly is held in a non-rotating position, for instance for obtaining the measurements, the longitudinal member is tree to rotate and continue drilling the borehole, wherein downhole measurements can be obtained with substantially no sensor movement or vibration. This is particularly useful in making NMR measurements due to their susceptibility to errors caused by tool vibration. In addition. the substantially non-rotating arrangement of sensors makes it possible to efficiently cam out VSPs, reverse VSPs and looking ahead of the drill bit. A clamping device is used, for instance, to hold the sensor assembly in the non-rotating position. The sensor assembly of the present invention can include any of a variety of sensors and/or transmitters for determining a plurality of parameters of interest including, for example, nuclear magnetic resonance measurements.

Title: Method and apparatus to tension hot strip during coiling
Inventor: BRASHEAR JOSEPH OSCAR
IPC: B21B39/00
Filed: 1999-03-17
Abstract: The present invention is to tension and guide hot strip for coiling in a hot strip mill, the hot strip mill includes a runout table with driven rollers (18, 20) for delivering hot strip from a train of finishing mill stands (10, 12, 14, 16) along a pass line of a runout table to a coiler (24). The coiler having driven mandrel (44) for coiling strip thereon and pinch rolls (26, 28) having an operative position to direct the leading end of strip from the runout table to the toiler and tension the deflected leading end portion of strip during the formation of initial convolutions of coiled strip on the driven mandrel. Gag roll assembly (22) includes gag rolls (66, 68) upstream of the pinch rolls at the runout table for tensioning strip conveyed by the runout table after a trailing strip end emerges from the train of finishing mill stands. An actuator (62) for moves the gag roll assembly from an inoperative position remote to the pass line on the runout table into an operative position wherein strip is deflected from the pass line sufficiently to partly wrap about a roll face surface of the gag roll thereby tensioning the strip during coiling. The gag rolls are driven by motors (74) to maintain a synchronous speed relation between the roll surface of the gag rolls and the speed of the strip to avoid scratching or marking of the strip.

Abstract: The pixel clock of a raster output scanning (ROS) system modulates an emitted light beam to provide pixel placement along a scan line. A method calculates the pixel clock frequency shifts to correct non-linearity of the scan line in a ROS. A  data smoothing polynomial is calculated for the non-linearity of the pixels along the scan line. The needed frequency shift based on the polynomial to the first or higher orders is calculated and stored in a frequency shift look-up table. The calculated frequency shift from the frequency shift lookup table modifies the nominal pixel clock frequency to correct for the measured scan linearity of the ROS by modulation of the light beam.
