Title: Flocculation magnetic separator
Inventor: TERUI SHIGEKI
IPC: C02F1/52
Filed: 2012-01-26
Abstract: Provided is a flocculation magnetic separator which reduces the used amounts of magnetic powder as well as the collected flocs thus recovered, without using a chemical such as hydrochloric acid.  The flocculation magnetic separator comprises a return and addition unit (18) which returns the collected flocs discharged from a magnetic separation unit (16) to a raw water supply pipe (12) at an upstream position of a rapid stirring tank (26) and at an upstream position where a flocculant is added. This process for returning the collected flocs to the raw water supply pipe (12) enables the collected flocs to be recycled without using a chemical such as hydrochloric acid. Further, this process also enables the magnetic powder contained in the collected flocs to be recycled, resulting in the reduction of the used amounts of brand-new magnetic powder.

Patent CA-2833316-A1 (CA)
Inventor: EICK PETER M
IPC: G01V1/37
Filed: 2012-05-11
Abstract: The invention relates to processing seismic data that includes signals from at least two sources and typically three or four sources where source separation is necessary for geophysical analysis. Specifically, the present invention is a process for correcting data prior to inversion where the correction is provided to correct for the filtering effect of the earth. The earth is a non homogenous seismic propagator that causes distortions of wavelets of seismic energy related to the source and receiver azimuth and offset that makes the identification of source specific data within the composite data harder to identify. Computing an earth response and correcting for the effects of the earth on the wavelets provides for more resolution and more clarity in the resulting data and better geophysical interpretation.

Abstract: A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas. A method of forming a multi-ply tissue involves conveying a base sheet through a nip between an impression roll and a pattern roll to produce an embossed base sheet having a back side possessing projections, applying adhesive to the back side of the embossed base sheet at spaced apart locations, and applying a flat backing sheet to the back side of the embossed base sheet so that the backing sheet adheres to the back side of the embossed base sheet at said spaced apart locations. A method of producing an embossed tissue involves successively conveying a base sheet through a nip between a first impression roll and a pattern roll, and conveying the base sheet through another nip between the pattern roll and a second impression roll, wherein the second impression roll is made of rubber having a lower hardness than the rubber from which the first impression roll is made.

Title: Broken rotor bar detection based on current signature analysis of an electric machine
Inventor: NETI PRABHAKAR
IPC: G01R31/34
Filed: 2014-03-27
Abstract: A method for detection of rotor bar faults in an electric machine is provided. The method includes acquiring electrical signals from the electric machine that are representative of the operative condition of the machine. The symmetrical components from the electrical signals are eliminated by squaring an instantaneous value of each data point from the electrical signals and summing the squared values. The method further includes the step of eliminating discontinuities in the electrical signals by applying a window function to compute weighted representation of the squared values. Furthermore, the method includes the step of normalizing the weighted representation to obtain spectral information. The faults in the rotor bar are detected by analyzing the spectral information obtained after normalization.
