Publication number: 20090053060Abstract: Wind turbines or generators are provided with a larger operating range, and made more efficient through the use of controlling the Bernoulli Effect on air foil blades. The control is effected through the use of rotating bands arranged over at least part of the surface of the blades. The direction of the moving bands is reversible so as to increase or decrease the lift provided by the Bernoulli Effect. In the present invention, greater torque can be developed on the wind generator without increasing the wind speed.Type: ApplicationFiled: June 5, 2008Publication date: February 26, 2009Inventor: Theodore M.

Patent number: 6774992Abstract: The invention relates to the use of ratios, products and non-linear functions of adsorption, emission or scattering of light as variables in standard regression and chemometric techniques to predict a characteristic or property of a solid or liquid. The use of one or more non-linear functions within a relationship between measured spectral properties and characteristic properties of solutions and solids provides an improved means to determine a property when the intensities represent or relate to components that are colinear or interelated due to restraints associated with composition, chemical processes, or molecular structure. The invention relates to the use of ratios of Raman peak intensities to predict the properties of a solution or a solid such as pulp that is processed with the solution. The intensity of the Raman shifted light is used to create Raman peak intensity ratios. These Raman intensities are related to the concentration of species dissolved in the liquid.Type: GrantFiled: February 7, 2000Date of Patent: August 10, 2004Assignee: Alberta Research Council Inc.Inventors: Theodore M.

Publication number: 20040084570Abstract: The invention utilizes a computer-controlled moving band, typically on an airplane, to increase the apparent speed and therefore the lift of any body moving through a fluid. The invention will allow greater precision of control. One benefit is that take-offs and landings can be carried at reduced speeds and with greater loads. This control will also adjust boundary layer to adjust drag thereby allowing more flexibility in wing design.Type: ApplicationFiled: October 30, 2002Publication date: May 6, 2004Inventor: Theodore M.

Patent number: 6643016Abstract: A spectrometer or multiple wavelength absorbance detection method and apparatus providing improved accuracy for an array of measurements at different wavelengths. The spectrometer utilizes a multiple wavelength illumination system with an array of independent detectors with different pathlength cells, where each cell is illuminated with predominately monochromatic light after separation by a light dispersing element. Each sample cell has an optical pathlength, optics and photodetection device that are optimized for its particular wavelength to accurately measure absorbance through an expected substance.Type: GrantFiled: May 2, 2001Date of Patent: November 4, 2003Assignee: Alberta Research Council Inc.Inventors: Theodore M.

Patent number: 6474354Abstract: A method and apparatus for determining and controlling a property of colloidal substances that undergo at least one of a temperature dependent phase transition and a temperature dependent adsorption-desorption process is disclosed. The colloidal particles are characterized by performing successive measurements of light attenuation or emission by a colloidal mixture at two or more temperatures and at one or more wavelength. The difference or ratio of the measurements at two or more temperatures provides a measure of the colloidal stability with respect to temperature. The amount of certain organic colloids that are unstable to temperature variation may be determined from the magnitude of the measurement change. This method may be specifically applied to determining the tackiness and propensity to deposit of colloidal pitch or wood resin in pulp or paper process water as an indication of the effectiveness of a chemical control program.Type: GrantFiled: June 11, 2001Date of Patent: November 5, 2002Assignee: Alberta Research Council Inc.Inventors: Theodore M.

Patent number: 6263725Abstract: A method and apparatus are for characterizing colloids by successive measurements of light attenuation or emission of a colloidal mixture at two or more temperatures and at one or more wavelengths. The difference or ratio of the measurements at two or more temperatures provides a measure of the colloidal stability with respect to temperature. The amount of certain organic colloids that are unstable to temperature variation may be determined from the magnitude of the measurement change. In appropriate mixtures, this method provides a means to distinguish components of colloidal substances based. This method may be specifically applied to determining the stability and concentration of colloidal pitch or wood resin in a pulp or paper process water. In this context it may be used to distinguishing colloidal pitch or wood resin from talc, clay, carbon black, or other fillers.Type: GrantFiled: September 18, 1998Date of Patent: July 24, 2001Assignee: Alberta Research Council Inc.Inventors: Theodore M.

Patent number: 6134952Abstract: On-line measurements of an amount of dissolved solids in a liquid sample are determined by using both conductivity and UV measurements. More particularly, an amount of dissolved solids in a pulp and paper mill process water or effluent is determined by irradiating at least a portion of a liquid sample with ultraviolet light and subsequently measuring an absorption of the light by the liquid sample. Furthermore the conductivity of the liquid sample is measured and subsequently a computation is from a first relationship between the measured absorption of the first wavelength by the liquid sample and the measured conductivity of the liquid sample using a suitably programmed processor.Type: GrantFiled: September 18, 1998Date of Patent: October 24, 2000Assignee: Alberta Research Council Inc.Inventors: Theodore M.

Patent number: 6023065Abstract: A method and an apparatus for monitoring and controlling a characteristic of process waters or effluents from wood pulp bleaching, pulping and paper making processes utilizing a bleaching agent such as hydrogen peroxide (H.sub.2 O.sub.2), Na.sub.2 S.sub.2 O.sub.4, ClO.sub.2, Cl.sub.2 or O.sub.3 or a pulp delignification process utilizing a delignification agent such as NaOH, Na.sub.2 S, O.sub.2, Na.sub.2 SO.sub.3, and enzymes including ligninase, xylanase, mannanase, laccase, and peroxidase are disclosed. This is done by obtaining at least three measurements of ultraviolet-visible light from the effluent by taking a first measurement measured at a first wavelength, a second measurement measured at a second wavelength, and a third measurement at a third wavelength, formulating two ratios from the three measurements and using the ratios for computing an empirical value of the characteristic of the effluent.Type: GrantFiled: March 10, 1997Date of Patent: February 8, 2000Assignee: Alberta Research CouncilInventor: Theodore M.
