Title: Method and apparatus for leak detection and pipeline temperature modelling method and apparatus
Inventor: BAUMOEL JOSEPH
IPC: G01M3/28
Filed: 1994-05-25
Granted: 2002-11-26
Abstract: A method and apparatus of leak detection for a pipeline.  The method includes dividing the pipeline into a plurality of segments, a first site station provided at the beginning of each segment and a second site station provided at the end of each segment, dividing each segment of the pipeline into a plurality of hypothetical pipeline sections, each section having the same nominal volume, measuring the liquid flow into the first section and determining a volume of liquid that has passed the first site station for a defined period, measuring the temperature of the liquid entering the first section at the first site station, measuring the liquid flow out of the last pipeline section of the segment and determining a volume of liquid that has passed the second site station for the defined period, measuring the temperature of the liquid leaving the last section at the second site station, measuring the temperature of the ambient to the pipeline at the first site station or that representative of the topography of the segment, measuring the temperature of the ambient to the pipeline at the second site station or that representative of the topography of the segment, computing the effect of the measured ambient temperatures at the first and second site stations on the sections intermediate the first and second site stations, computing the change in temperature of each section intermediate the first and second site stations due to conversion of kinetic energy into thermal energy and radiation and conduction of energy to or from the section, computing the change in volume of each section      of pipeline wall and the change in volume of the liquid in each section based on the computed change in temperature of each section, determining the difference in measured volume between the volumes determined that have passed the first and second site stations for the defined period, correcting the difference in measured volume between the first and second site stations by adding or subtracting the change in the liquid and pipeline wall volume of all sections of the segment during the defined time period, comparing the corrected difference in measured volume between the first and second site stations with a threshold level, and generating an alarm signal if the difference exceeds the threshold level.
Patent CA-2125136-C (CA)
Inventor: CHIARI MARCELLA
IPC: C08F220/58
Filed: 1992-08-05
Granted: 2003-12-30
Abstract: Matrices for electrokinetic and chromatographic separations, based on a unique class of mono- and disubstituted (on the amido nitroagen) acrylamides (e.g., acrylamido-N-ethoxy ethanol, acrylamido-N, N-di-ethoxy ethanol) offer the following ad-vantages: a) strong resistance to alkaline hydrolysis (most zone separations occurring at basic pH values); b) a high hydrophilici-ty and c) greater porosity, due to the larger M r value of the monomers. Such matrices can be prepared as 'chemically cross-linked' gels or as 'physical gels', the latter consisting of'strings' of monofunctional monomer in the absence of cross-linker, at concentrations above the entanglement threshold. It is moreover possible to further increment the gel porosity by polym-erizing it in presence of laterally-aggregating agents (e.g., polyethylene glycol of M r 6-20000 Da), thus obtaining matrices which allow better resolution of large M r proteins and of nucleic acid fragments; by polymerizing the matrix in presence of a gradient of the laterally-aggregating agent, it is possible to obtain a porosity gradient even at constant per cent of monom-ers in the gel. Finally, photopolymerization (e.g., with methylene blue and a redox couple, sodium toluenesulfinate and di-phenyliodonium chloride and light), instead with the standard red/ox catalysts, prevents formation of N-oxides of amines present in the polymerizing solution.

Abstract: In a method and a circuit arrangement for driving semiconductor switches in a series circuit, in which a voltage limiting device is assigned to each semiconductor switch, the power losses of the voltage limiting devices are detected by a control equipment for equalizing the voltage distribution across the semiconductor switches. The control equipment generates modified control pulses for each semiconductor switch from a common control pulse on the basis of the detected power losses of the voltage limiting devices.      By this means, the power loss of the voltage limiting devices is controlled to a minimum.

Title: Method to reduce forming fabric edge curl
Inventor: SIMS JOE WILLIE
IPC: D21F1/00
Filed: 1996-02-23
Granted: 2001-01-23
Abstract: A method for reducing or eliminating forming fabric edge curl includes slitting or scoring the knuckles formed by cross-machine direction yarns (14) on the long-shute knuckle side (16) of a papermaker's forming fabric (10). The knuckles are scored or slit to a depth no greater than half the diameter of the cross-machine direction yarns. At least one such slit or score (18) is provided per knuckle (20). The scoring or slitting has the effect of bringing the ratio between the shrink forces acting on the two sides of the forming fabric in the cross-machine direction closer to unity, and, in turn, reduces or eliminates the edge curl resulting from shrinkage in the cross-machine direction.

Abstract: By localizing a point D on an optical axis, a virtual image is determined and compared with a measured virtual image. Using an iterative method, the point D can be shifted until the calculated and measured virtual images coincide and these data can then be used to determine an absolute spatial co-ordinate for a point on the surface. This method can be used, for example, in charting the surface of the cornea of an eye which has a reflecting film of tears.
