摘要： A skew detection and correction system, and method of correcting skew, in a conveyor system having an endless web that is propelled in a longitudinal direction, includes providing a skew detector and determining if at least some of the cross members of the web are non-perpendicular to the longitudinal direction and providing a differential lubricant application. The lubricant applicator is responsive to the skew detector and applies a relatively greater amount of lubricant to one lateral side of the web than to the other side of the web. This causes the side of the web receiving less lubricant to stretch more than the other side to reduce the difference in the amount of stretch.

摘要： A nuclear magnetic resonance (NMR) system, and related method, develops two or more regression equations or models for a particular polymer property of interest (e.g., melt index or MI) during a calibration procedure using known samples of a material. The polymer material can be, for example, a plastic (e.g., polyethylene, polypropylene, or polystyrene) or a rubber (e.g., ethylene propylene rubber). Regression models for one or more discrete (i.e., two-valued) variables also are developed during calibration, and these models allow a prediction to be made about which of the two or more property (e.g., MI) models should be used for any particular sample of unknown material. The prediction obtained from the discrete variable model indicates which of the two or more models will produce the most accurate estimation of the property of interest for the unknown sample. The best model is thus selected, and then it is used to estimate the property of interest.

摘要： A pulsed nmr analysis system for polymers materials extracted from industrial processes at a mobility enhancing temperature (at or above glass transition temperature for amorphous polymers, at the crystalline transition temperature for crystalline and semi-crystalline polymers). The sample is measured via nmr techniques and results correlated to viscosity and melt index or melt flow (which are related to average molecular weights). The nmr system (in or out of resonance) includes: sample throughput system (P, LI, V1, V2) and user system controls (104) to establish digitized free induction decay curves (C), from which components functions are determined using linear or non-linear regression techniques to correlate the curve components to the target nuclei and to flow rates in plastics. Substantial improvement of correlation of nmr derived constants and equations of a free induction decay curve with the foregoing polymer properties is obtained via (1) conducting the nmr process at a mobility enhancing temperature (normally elevated compared to the industrial process temperature of the industrial process) and (2) holding temperature substantially constant at such elevated temperature.

摘要： Apparatus and process for measuring mass flow of a slurry mixture of two components of materials, such as a flow of catalyst solid particles (the first component) or droplets in a fluid carrier (the second component). The slurry mixture is added to a process stream (10) or batch reactor. The flow velocity and the volume fraction of one component are measured and combined with the known specific gravity, of the component being measured, and the physical dimensions of the pipe, in which the slurry mixture is flowing, to determine the mass flow of the component. The flow velocity is measured by correlating signals at two separated locations along the flow path, and the volume fraction is measured by combining the known dielectric constants of each of the materials in the mixture and the measured capacitance of the mixture. The capacitance is measured from electrodes which may be isolated from the flowing materials in some applications, but not isolated from the flowing materials in other applications. The temperature (9) and pressure (11) are compensated in the final calculation, and the mass flow result is used to control, via feedback, the amount of such materials delivered. Also, a subtraction technique to remove interfering power line noise is implemented to improve sensitivity.

摘要： A method for producing a gas and a liquid in a subterranean well includes the step directing a gas flow in a well annulus through one or more baffle plates to separate at least some of the liquid from the gas. The method can also include the steps of directing the separated liquid down the annulus towards a producing formation of the well, dehydrating the gas flow proximate to a surface of the well, and then directing the dehydrated gas flow to the surface. A system for performing the method includes a set of baffle plates located proximate to the producing formation configured to provide a tortuous path for the gas flow through the annulus, and a single baffle plate located proximate to the surface configured to dehydrate the gas flow. In addition to separating the liquid from the gas flow, the set of baffle plates maintains a single phase wet gas above the baffle plates, and a liquid phase below the baffle plates.

摘要： An on-line nuclear magnetic resonance (NMR) system, and related methods, are useful for predicting one or more properties of interest of a polymer. In one embodiment, a neural network is used to develop a model which correlates process variables in addition to manipulated NMR output to predict a polymer property of interest. In another embodiment, a partial least square regression technique is used to develop a model of enhanced accuracy. Either the neural network technique or the partial least square regression technique may be used in conjunction with a described multi-model or best-model-selection scheme according to the invention. The polymer can be a plastic such as polyethylene, polypropylene, or polystyrene, or a rubber such as ethylene propylene rubber.

摘要： A method is provided for maintaining threaded joints of a tool string to prevent jamming of the threads by rotation of a tool string required during movement of the tool string through a generally horizontal production portion and a curved bore portion of the well. Each thread joint is formed by use of an externally threaded pin and box configuration with the external diameter of the box substantially exceeding the external diameter of the pin. The cooperating threads are configured so that limited relative axial movement produces locking of cooperating threads against realtive rotation after full engagement. Relative axial movement is produced during makeup of the tool string by rotating a sleeve threadably mounted on the exterior of the pin and engagable to produce axial movement. The sleeve has an external diameter less than the box to prevent frictional engagement of the sleeve with the bore wall of the curved bore portion of the well.
