Title: Innovations of Alain André Roche
Introduction
Alain André Roche is a notable inventor based in Montreal, Canada. He has made significant contributions to the field of pulp and paper technology, holding 2 patents that showcase his innovative approaches to refining processes.
Latest Patents
One of his latest patents is a "Method of refining wood chips or pulp in a high consistency conical disc refiner." This method aims to improve pulp quality at high production rates on conical disc refiners. It allows for a reduction in refining intensity by increasing fiber residence time while avoiding plate plugging issues typically associated with high discharge consistency. The method involves increasing inlet consistency through in-feed dilution and flat zone dilution, while maintaining a fixed optimum discharge consistency by adding dilution water within the conical zone. This results in increased residence time and decreased refining intensity.
Another significant patent is for a "Diagnostic for poorly tuned control loops." This invention provides a method and apparatus for automatically diagnosing poor performance in control loops. It determines if malfunctions are primarily due to poorly adjusted controller tuning parameters. The method leverages the amplification of disturbances in a narrow frequency range around the resonant frequency, measuring errors over time to analyze power spectral density and derive diagnostic values.
