Abstract: A fabric laminate (10) comprises first and second stretch fabrics (11 and 12) having an intermediate adhesive securement layer (13) between them. The adhesive securement layer (13) is in the form of a regularly repeated pattern which comprises an array of aligned adhesive elements (14) arranged in successive generally horizontally and vertically extending rows. The array of adhesive elements (14) is capable of offering resistance to elongation as the laminate (10) is subjected to distortion, with the pattern having a differential elongation characterized as offering different magnitudes of resistance to elongation when the fabric laminate (10) is subjected to distortion in selected different directions. The adhesive securement layer (13) is predeterminedly oriented in accordance with its differential elongation and the stretch characteristics of fabrics (11, 12) such that the resistance to elongation offered by the laminate (10) is determined by the pattern and orientation of the individual adhesive elements (14) in conjunction with the stretch characteristics of the fabrics (11, 12). The laminate (10) may be employed to reinforce items of clothing, particularly underwear and the like.

Patent CA-2182545-A1 (CA)
Inventor: DOUGLAS JOEL
IPC: C12Q1/54
Filed: 1996-08-01
Abstract: A multilayer reagent test strip measures the concentration of analyte in a liquid sample that is applied to it. The sample is guided to a number of assay areas arrayed along the strip, where the analyte can react with a reagent to cause a color change. Each assay area also includes an inhibitor for the color-change reaction. The inhibitor concentration increases in successive assay areas; thus, the number of areas that change color is a measure of the analyte concentration. The test strip is particularly adapted for measuring glucose in awhole blood sample. In a preferred embodiment, the sample is guided to the assay areas along a path formed by crushing selected areas of a membrane, and the assay areas are uncrushed areas of the membrane.

Title: Production wells having permanent downhole formation evaluation sensors
Inventor: TUBEL PAULO
IPC: E21B47/01
Filed: 1996-09-09
Abstract: A downhole control system for a production well is associated with permanent downhole formation evaluation sensors which remain downhole throughout production operations. These formation evaluation sensors may include, for example, neutron generator, gamma ray detector and resistivity sensors which can, in real time, sense and evaluate formation parameters including important information regarding formulation invading water entering the producing zone. Significantly, this information can be obtained prior to the water actually entering the producing geological formation and therefore corrective action (i.e. closing of a valve or sliding sleeve) can be taken prior to water being produced. This real time acquisition of formation data in the production well constitutes an important advance over current wireline techniques in that the present invention is far less costly and can anticipate and react to potential problems before they occur. In addition, the formation evaluation sensors themselves can be placed much closer to the actual formation (i.e., adjacent the casing or downhole completion tool) then wireline devices which are restricted to the interior of the production tubing.

Title: Method and Apparatus for Connected and Degraded Text Recognition
Inventor: BOSE CHINMOY BHUSAN
IPC: G06K9/62
Filed: 1992-10-26
Abstract: The present invention provides a method and apparatus for enhancing and recognizing connected and degraded text. The enhancement process comprises filtering a scanned image to determine whether a binary image value of an image pixel should be complemented, determining whether complementing the value of thepixel reduces the sharpness of wedge-like figures in the image, and complementing the binary value of the pixel when doing so does not reduce sharpness. The recognition process may comprise determining primitive strokes in a scanned image, segmenting the scanned image into sub-character segments based on the primitive strokes, identifying features which characterize the sub-character segments, andcomparing identified features to stochastic models of known characters and determining an optimum sequence of known characters based on the comparisons through the use of Viterbi scoring and level building procedures.

Title: Method for reducing formation of polychlorinated aromatic compounds during air oxychlorination of c1-c3 hydrocarbons
Inventor: JOHNSTON VICTOR JAMES
IPC: C07C17/152
Filed: 1996-11-19
Abstract: An improved process is disclosed for manufacturing chlorinated hydrocarbon by way of a once-through air-based oxychlorination process which yields reduced levels of environmental toxins such as chlorobenzenes, polychlorinated biphenyls, polychlorinated dibenzodioxins and polychlorinated dibenzofurans. The process involves fixed bed or fluid bed catalyzed oxychlorination of a hydrocarbon reactant containing from 1 to 3 carbon atoms.      The oxychlorination process consists of contacting the hydrocarbon reactant with air or oxygen enriched air and hydrogen chloride in the presence of the oxychlorination catalyst in a heated reaction zone operated at from 150°C to 600°C and recovering chlorinated hydrocarbon from the effluents of the reaction zone. The improvement consists of the use of air which is pretreated before use in the operated oxychlorination process by a means for removal of the aromatic hydrocarbons.
