Patent CA-2277170-A1 (CA)
Inventor: BOUVYN PATRICK
IPC: G01N21/89
Filed: 1998-01-28
Abstract: The present invention relates to a detector (1) of foreign fibres and to a corresponding detection method, which can be used for detecting foreign fibres and foreign materials in a measurement object (5) in the textile industry, for example in yarns, slithers and unformed fibre bands on, for example, weaving machines, spinning machines, bobbin winding machines, doubling machines, cards, drawing benches and bobbin frames ... The principle of the detection is based on the fact that a measurement object (5) and foreign fibres or materials which are situated in the measurement object (5) absorb the light emitted into the measurement volume (4) by a light source (2) to different extents. All the light in the measurement volume (4), or a representative sample thereof, is measured by photodetectors (3) and converted into a photoelectric signal. Comparison of this signal with a signal measured when the measurement volume (4) was empty provides the absorption of the measurement object (5), from which the level of contamination of the measurement object (5) can be derived by interpretation.

Abstract: A one-trip system for removing casing from a wellhead is described. The string includes a cutting device spaced at the required depth and a grappling device above it at the appropriate location. A swivel tool, such as a marine swivel, is used in conjunction with a seal-pulling assembly so that after cutting the casing, the seal assembly can be pulled without an additional trip into the well. The grappling device or spear can be hydraulically actuated to grab the casing for removal from the wellbore. The spear features a drop-in restrictor which allows sufficient flow during cutting operations with a mechanical cutter without actuating the spear, while at the same time allowing actuation of the spear by circulation after dropping in the restrictor after the casing section has been cut.
Patent CA-2302994-A1 (CA)
Inventor: IVANOV EVGENY V
IPC: G01J3/453
Filed: 2000-03-24
Abstract: Static Fourier transform spectrometers, as well as multichannel dispersive spectrometers, usually have a relatively low value of the product of resolving power and relative free spectral range. This value is limited by the number of pixels in a line of the detector array used in the spectrometer. In this invention, a substantial increase of the SR-factor over the prior art static Fourier spectrometers is provided by means of introducing a stepped retardation in a static double beam Michelson or Mach-Zender interferometer with two-dimensional detector array. The stepped retardation can be introduced into the interferometers by using a stepped-profile reflective (10) or refractive element into one of the interferometer arms. A  two-dimensional interference pattern that contains folded interferograms is formed on the detector plane, captured by the detector array, and digitized by the analog-to-digital converter in the signal processing unit. Then the interferogram, as a function of the light intensity vs.  linearly increasing retardation, can be reconstructed by merging the folded interferograms corresponding to adjacent lines of the interference pattern together, and the original spectrum of the analyzed radiation can be retrieved by applying the Fourier transform to the reconstructed interferogram.

Title: System and method for mobile assisted admission control
Inventor: PERSSON HAKAN
IPC: H04W74/08
Filed: 1998-09-15
Abstract: A system for inhibiting the transmission of an access request message from a mobile station when either the system is incapable of granting access at the class of service desired by the mobile or access by the mobile at that class of service would increase the interference level of the target base station or a neighboring base station past its interference capacity. In one embodiment, each base station broadcasts a maximum data rate access parameter and any mobile receiving that parameter and seeking access at a greater data rate refrains from transmitting an access :request message. In another embodiment, each mobile calculates from its path loss to the base station the power level it must transmit in order to gain access as well as the effect of that transmission on the interference level of both the target base station and neighboring base stations. If transmission at the required power level would increase the interference level of any base station past its maximum capacity, the transmission is inhibited. The system is most effective in CDMA mobile cellular radio systems.

Title: Application of deuterium oxide in producing silicon containing and metal containing materials
Inventor: ZHANG PINGQUING
IPC: C03C3/06
Filed: 2000-05-29
Abstract: Deuterium oxide, D2O, also called heavy water, was used for the hydrolysis of silanes and metal compounds. The D2O-hydrolyzed silanes polycondense much easier than H2O-hydrolyzed silanes, resulting in a fast Si-O-Si network build up. The most important feature of using D2O is that the final materials are 100% of O-H free and the residual O-D bond does not have absorption peak in the range of 1.0 to 1.8 µm, which is crucial in reducing optical loss at the wavelength of 1.3 and, especially, 1.55 µm. O-H free sol-gel materials with low optical loss have been developed based on the process. The application of D2O can be applied in all kinds of hydrolysis involved processes, such as sol-gel process of silanes and metal compounds, and can be extended into other silica and metal oxides deposition processes, such as flame hydrolysis deposition (FHD) and plasma enhanced chemical vapor deposition (PECVD), wherever water is used.
