Title: Apparatus and method for particle comminution
Inventor: BRENHOLDT IRVING R
IPC: D21G9/00
Filed: 1996-05-21
Abstract: An apparatus and method are provided in which direct ohmic connection (G) is made to a comminution device (GD) (e.g., a wood chip or pulp refiner) to obtain transient voltages, existing on the refining elements, that are directly related to fiber impacts. These voltages, existing on the refining elements, that are directly related to fiber impacts. These voltages are characterized by severity (S) (i.e., magnitude), rate (N), rise time (RT) and polarity (+/-P). The characteristics of these voltages taken separately and/or in mathematical combinations predict the properties of refined wood chips and pulps, i.e., freeness, tensile strength, tear, burst, breaking length and fiber length. Signal characteristics further track refiner plate wear and detect the occurrence of "critical gap" (F) as well as the onset of plate clash.

Patent CA-2230564-A1 (CA)
Inventor: HAVERKAMP RICHARD GERARD
IPC: C25C3/20
Filed: 1996-08-28
Abstract: This invention provides apparatus and a method for measuring the concentration of alumina in a molten electrolyte in a smelter. A test anode (101) (a mimic of the actual cell anode) supplied from a computer-controlled voltage source (303) with several to about (100) rapid cyclic voltammetry sweeps seeks the voltage at which the anode effect occurs, as sensed by current measurement (305). In order to derive a measurement the voltage is compared within the computer (301) to previous measurements made from a calibration set of alumina samples in known concentrations. Brief rapid cycles and an improved electrode configuration help to provide results from the invention which are reproducible and accurate, and in addition the test electrode has a long life.
