Filed:

Feb 28, 2001

Appl. No.:

09/796004

Inventors:

Felix Alba - Murray UT, US

Assignee:

Felix Alba Consultants, Inc. - Murray UT

International Classification:

G06F 7/48
G06G 9/45
G06G 7/60
G06F 17/50

US Classification:

703 2, 703 1, 703 5, 703 6, 703 22

Abstract:

This invention relates to a method and apparatus for the fundamental prediction, analysis, and parametric studies of the interaction of multiply scattered waves of any nature (acoustic, electromagnetic, elastic) with particulate composites (solid or fluid particulate phases included in a solid or fluid phase). It comprises of: a) a Prediction Engine to predict the composite physical attributes from those of the constituent phases, b) an Inversion Engine to estimate a subset of the attributes of the constituent phases and composite from the rest of those attributes, and c) an ergonomic Graphical Interface to enable the user to easily set up complex simulation experiments for the analysis, and synthesis of real systems in which generic waves interact with composites. The Prediction Engine is suitable for integration into existing acoustic or optical particle size analyzers to thereby extending their concentration ranges by at least two orders of magnitude.

International Classification:

G01N 1502

US Classification:

73 6141

Abstract:

The present invention relates to method and apparatus for determining the size distribution and concentration of particles in suspensions, emulsions or aerosols utilizing ultrasonic excitation. The invention is applicable over a wide range of particle sizes (0. 01 to 1,000 microns) and concentrations (0. 1% to 70% by volume). The present invention is particularly useful for industrial on-line measurement and control of highly concentrated slurries. The method comprises the steps of directing ultrasonic waves through the suspension at selected discrete frequencies over a selected frequency range and measuring the attenuation of the ultrasonic waves passing through the suspension for each of the selected discrete frequencies to thereby obtain a measured attenuation spectrum for the suspension over the selected frequency range. The method further comprises the steps of calculating a set of attenuation spectra for the ultrasonic waves passing through the suspension over the selected frequency range using a set of original values of particle size distribution and concentration and comparing the measured attenuation spectrum with the calculated attenuation spectra to derive an approximate match between at least one of the calculated spectra and the measured spectrum within a selected error range. The method further comprises the step of selecting the size distribution and concentration of the particles used to calculate the attenuation spectra to thereby derive a new set of values of particle size distribution and concentration corresponding to the measured attenuation spectrum.

Abstract:

Technology is described for an electromagnetic apparatus and system that sorts different electrically conductive metals. In one example, an electrodynamic sorting circuit includes a wire-wound, gapped, core (WWGC) and a capacitor bank. The WWGC includes a magnetic core including a gap, and an electrical conductor coiled around the magnetic core. A current in the electrical conductor is configured to generate a magnetic field in the magnetic core and the gap. The capacitor bank is coupled in series with the electrical conductor of the WWGC. Various other circuitries, systems, devices, components, and methods are also disclosed.
