Patent CA-2369256-A1 (CA)
Inventor: BALCERZAK ROBERT J
IPC: E01C9/00
Filed: 2002-01-24
Abstract: The invention provides extruded polyvinylchloride curbing for use in defining and setting the edges of an area covered with paving stones, such as interlocking concrete paving stones. The curbing is buried in the ground and the paving stones abut a vertical leg of the L-shaped curbing, thereby defining the edge. The vertical leg of the curbing is integrally formed with a base leg at right angles thereto, the base leg having a raised, longitudinally extending ridge therein. A third leg extends longitudinally of the curbing and is attached to the vertical leg by a living hinge close to the upper edge thereof. The third leg exhibits a degree of flexibility and is provided with a latching lip along the free edge thereof, which lip is engageable with a corresponding flange along the upper inner edge of the ridge. When the third leg is engaged with the flange the curbing exhibits substantially greater rigidity than when it is not engaged. The curbing may be provided with cut-outs in the base leg, spaced apart along the length thereof to allow the curbing to define arcuate edges for the laid paving stones. The third leg can be cut transversely, or longitudinally along the living hinge, to aid in defining the arcuate edge. Flanges or walls along the free edges of the vertical and base legs can be interlocked together when one length of curbing is inverted relative to another length, for storage or transportation of the curbing.

Title: Multi-frequency electromagnetic wave resistivity tool with improved calibration measurement
Inventor: BARTEL ROGER
IPC: G01V3/30
Filed: 2000-08-03
Abstract: A resistivity tool for use in an LWD system includes an asymmetric transmitter design with multiple transmitters capable of generating EM signals at multiple frequencies. A pair of receivers (R1, R2) are positioned at one end of the transmitter array to detect the EM signals after they have traversed the region in the vicinity of the borehole. A calibrating transmitter (Tc) is positioned between the receivers (R1, R2), which can be used in two different modes of operation. In a first mode, the calibrating transmitter (Tc) is used to calibrate the receivers (R1, R2) for thermal drift. In this calibration mode, an attenuation correction and phase shift correction can be calculated to correct for thermal drift of the receivers while the resistivity tool is in the borehole. Thus, the thermal drift of the receivers can be re-calibrated as often as desired while the tool is in the well. In a second mode of operation, the calibrating receiver may be used to measure the resistivity of the drilling mud in the borehole.
