Patent CA-2293623-A1 (CA)
Inventor: JANSSEN WIM
IPC: D21H17/52
Filed: 1998-06-10
Abstract: The invention relates to a method for producing paper, mat, laminate or similar material web using a binder feeding mechanism and by subsequent hardening.      In this method, a water-dilutable acrylate in the form of a binder is fed to the material web at the binder feeding mechanism. The material web is then hardened by an electron beam, after the water content has been evaporated off. After feeding the binder, or after the impregnation process, the material web containing the noncrosslinked acrylate is dried and the water is evaporated from the binder, preferably an emulsion.      The material web is then printed and crosslinkage or polymerization begun. After printing, a varnish is applied that is capable of being hardened by an electron-beam. The material or paper web can be pressure-impregnated with the acrylate.

Title: Measurement-while-drilling assembly using gyroscopic devices and methods of bias removal
Inventor: NOY KOEN ANTONIE
IPC: E21B47/022
Filed: 1998-12-04
Abstract: This invention provides a measurement-while-drilling (MWD) downhole assembly for use in drilling boreholes which utilizes gyroscopes, magnetometers and accelerometers for determining the borehole inclination and azimuth during the drilling of the borehole. The downhole assembly includes at least one gyroscope that is rotatably mounted in a tool housing to provide signals relating to the earth's rotation. A device in the tool can rotate the gyroscope and other sensors on the tool at any desired degree. A processor in the tool combines measurements from the sensors taken at a plurality of positions at the same depth to determine the systematic bias in the sensors before further processing. Accelerometers in the MWD tool provide gravity measurements from which the toolface and inclination are determined. The unbiased gyroscopic measurements are used in conjunction with the tool face and inclination measurements to determine the azimuth and tool face with respect to true north. Three axially spaced apart magnetometers may be used to correct for local magnetic disturbances. Additionally, when measurements are made with magnetic, accelerometer and gyrospic measurements along three different axes, the unbiased measurements may be combined to provide an improved determination of the tool orientation.
