Title: A probe indicating intermaterial boundaries
Inventor: KAIPIO JARI
IPC: G01F23/263
Filed: 2011-02-25
Abstract: The present invention describes a method, apparatus and computer program for detecting the locations of boundaries between different materials in a desired measurement volume. The apparatus uses at least one measuring probe, the electrodes of which are characterized in that they together form an assembly that differs from a straight line. In addition, a volume at a further distance from the assembly can also be observed by the assembly, so that measurements can be conducted remotely and, on the other hand, the apparatus stays unbroken in diverse measurement situations. By using the EIT-measurement and applying for example a so-called 1D-s-method or methods of machine learning, electrical conductivity distributions in the measured volume are detected. As a result, the locations of the possible boundaries between different materials or for example thicknesses of different material layers are detected.

Title: Anaerobic membrane bioreactor for treating a waste stream
Inventor: EWING JOHN
IPC: C02F3/28
Filed: 2011-04-13
Abstract: A waste stream having anaerobically biodegradable components is fed to an anaerobic reactor where the components react with microorganisms to biodegrade the components and produce biomass and biogas. Mixing occurs in select portions of the anaerobic reactor, particularly the bottom and top portions of the reactor. Relatively heavy solids settle to the bottom and are mixed with the mixed liquor while relatively light or fine solids float to the top portion of the anaerobic reactor where they are mixed with the mixed liquor. This leaves an intermediate or middle portion of the anaerobic reactor where the concentration of solids is relatively lower compared to the concentration of solids in the upper or lower portion of the anaerobic reactor.
