Patent CA-2306807-A1 (CA)
Inventor: MCFARLAND ERIC
IPC: G01N35/10
Filed: 1999-08-12
Abstract: Devices and methods for controlling and monitoring the progress and properties of multiple reactions are disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injecting liquids into the vessels at a pressure different than ambient pressure. In situ monitoring of individual reaction mixtures provides feedback for process controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight. Computer-based methods are disclosed for process monitoring and control, and for data display and analysis.

Abstract: A beam steerer (10) for steering a microwave beam (27) comprises a body (12) of magnetic material having an aperture (15) and magnetic coils (24, 26) for applying a gradient of magnetisation across the aperture (15). Tapered slots extending from the magnetic coils (24, 26) towards a central region of the aperture (15) are filled with a material (32, 34) having a lower magnetic permeability than the magnetic material of the body (12). Lower reluctance paths available through the central region of the aperture (15) allow more magnetic flux from the magnetic coils (24, 26) to penetrate through the central region than would be the case in a body of uniform material composition.

IPC: G01V1/38
Filed: 2000-05-23
Abstract: A planned survey comprises several lines of receivers, preferably bottom-fixed or otherwise maintaining a fixed position, in the survey area. The survey area is divided into a number of "bins" of a convenient shape and size, such as squares with a side equal to half the receiver spacing (when the receivers are equally spaced on the receiver lines). The data from the suite of shot and receiver positions are analyzed and all shot-receiver pairs that have a common sort point (CSP) are assigned to the spatial bin in which the CSP is located. The CSP maybe a common mid-point (CMP). The data within each bin are analyzed to give a figure of merit of the adequacy of the sampling for each bin. These figures of merit are displayed in a color display that makes the inadequacies of the sampling apparent, making it possible to modify the planned acquisition geometry prior to the actual deployment of the receiver lines. Alternatively, a figure of merit is determined for the overall survey. To facilitate the evaluation, a neural net may be trained to evaluate the survey based upon the figure of merit.

Title: Mass spectrometer with multiple capacitively coupled mass analysis stages
Inventor: VANDERMEY JOHN
IPC: H01J49/42
Filed: 2000-07-13
Abstract: A mass spectroscopy apparatus having two quadrupole mass analyzer stages is disclosed. Both stages are configured to transmit ions of the same mass to charge ratio and they are operated in series to provide a tandem mass analyzer having greater resolution than either stage has separately. The poles of the two quadrupoles are positioned axially and close together to minimize ion loss between the two stages.      The RF component of the potential across the two stages are kept in phase such that some poles of the first stage are always 180° out of phase with some poles of the other stage. Capacitors are provided to couple the out of phase poles of the two stages to one another, thereby compensating for a stray capacitance which arises between the in phase poles of the two stages.

Filed: 1999-02-19
Abstract: Bead transporter chucks for selective pick up and discharging of polymer beads for chemical synthesis or analysis, whereby repulsive field conductors are arranged around bead electrodes used for selectively attracting and retaining beads. Problems of bead control are addressed by adding repulsive fields to help guide and direct beads to desired or designated bead collection zones.  The repulsive electrodes create non-uniform electric fields that control, focus, and deflect charged beads in the vicinity of the bead collection zone, helping prevent multiple bead retention at intended bead collection zones. For better bead control, and allowing manipulation of beads with higher charge/mass ratios, dielectric material may be positioned around the bead electrode and between the bead electrode and the repulsive field conductor.  Multiple bead electrodes may be provided to form two or more bead collection zones, and these may be selectively addressed and controlled (e.g., x-y addressing) for individual and selective control of the bead collection zones.  Methods and applied voltages are given for using the bead transporter chuck to transport and dispense beads.

Title: Methods and apparatus for derivative-based optimization of wireless network performance
Inventor: HAMPEL KARL GEORG
IPC: H04B7/26
Filed: 2000-10-24
Abstract: Improved techniques for optimizing performance of a wireless network. In an illustrative embodiment, a derivative-based optimization process is applied to optimize an objective function of a network performance metric with respect to a number of network tuning parameter variables. The optimization may be based on first or higher order derivatives of the objective function with respect to the selected network parameter variables. The objective function may include, e.g., one or more of a maximization of network coverage, a maximization of network capacity, and a minimization of network resources. Additional network parameters which are not variables in optimization process serve as constraints to the optimization process. Advantageously, the invention substantially improves the process of designing, adjusting and optimizing the performance of wireless networks.

Abstract: Improvements in dispenser valve heads which may be connected to soft drink bottles or the like, wherein a valve body is obtained, a liquid circulation channel being provided between the spout and the fishing tube, said channel having a check valve. The rod of said valve is actuated by a command means whose the articulated arm is foldable over the valve body, having folding stops and having a strap provided with a retainer. Folding stops of the valve body and corresponding recesses of the articulated arm prevent that the latter being lowered by any accidental pressure, in which case the valve rod would be displaced and an unwanted release of liquid would be produced. For delivering the carbonated liquid it is first necessary to release the folding strap. In this way the articulated arm may be unfolded until it displaces through the command channel existing on the head walls.

Abstract: The present invention concerns fusion of Fc domains with biologically active  peptides and a process for preparing pharmaceutical agents using biologicall y active peptides. In this invention, pharmacologically active compounds are prepared by a process comprising: a) selecting at least one peptide that modulates the activity of a protein of interest; and b) preparing a pharmacologic agent comprising an Fc domain covalently linked to at least on e amino acid of the selected peptide. Linkage to the vehicle increases the hal f- life of the peptide, which otherwise would be quickly degraded in vivo. The preferred vehicle is an Fc domain. The peptide is preferably selected by pha ge display, E. coli display, ribosome display, RNA-peptide screening, or chemic al- peptide screening.

Abstract: An apparatus for sensing rotary position that is particularly suited for electrical rotary actuators. The sensing apparatus comprises a magnet and a hall effect detector, both of which are arranged along the axis of rotation. The hall effect detector senses the angle of the return loop of magnetic flux lines from the north to the south pole of the magnet. When the magnet rotates relative to the hall effect detector, the angle of the magnetic flux lines changes which is detected by the hall effect detector.  The arrangement of the magnet and the hall effect detector on the shaft axis of a rotary actuator avoids the magnetic flux line interference that is naturally produced by electrical actuators.
