Title: Methods and circuits for measuring the conductivity of solutions
Inventor: BLADES FREDERICK K
IPC: G01R27/22
Filed: 1993-07-13
Abstract: Improved circuits for measuring the conductivity of a solution confined between two electrodes in a cell compensate for series capacitance and parallel capacitance between the electrodes. A bipolar square-wave signal is applied to the cell. In one embodiment, the current through the cell is measured by an op-amp in current-to-voltage converter configuration. A feedback resistance employed with the op-amp in a feedback loop is controlled to a low value to ensure that the parallel capacitance is fully charged during an initial portion of each half-cycle of the drive signal. The feedback resistance is then selected so that the gain of the feedback loop is responsive to the range of the resistivity of the solution, and the measurement is made. The period of the bipolar signal is selected responsive to the selected loop gain, to ensure that a filter capacitor across the op-amp is fully charged, and to limit distortion caused by the series capacitance. More particularly, the rate of charge of the series capacitance is proportional to the solution resistance; by varying the period of the drive signal in accordance with the solution resistance, the distortion introduced by the series capacitance remains negligible.        In a further embodiment, charge proportional to the current through the cell is integrated across the op-amp, and the rate of charge is measured by measuring the time required to integrate the current to a predetermined level, and used to determine the resistivity of the solution. In this embodiment, the parallel capacitance is fully charged before each integration period begins.      The voltage developed across the series capacitance is constant and can be compensated mathematically.

Title: Process for bleaching of lignocellulose-containing material
Inventor: ANDERSSON LENNART
IPC: D21C9/153
Filed: 1992-04-27
Abstract: Abstract The present invention relates to a process for deligni-fication and bleaching of chemically digested lignocellulose-containing pulp, where the pulp, from which essentially no magnesium ions have been removed by acid wash, is treated with a complexing agent at a pH in the range from 4 up to 9.0 and at a temperature in the range of from 26 up to about 100°C, whereupon the pulp is bleached with ozone. The initial treat-ment with a complexing agent removes the ions of certain metals detrimental to the subsequent ozone bleaching while retaining in the pulp the desirable ions, primarily of alka-line earth metals. Thereby, the selectivity in the deligni-fication is increased. Subsequently, the pulp is bleached with a peroxide-containing compound in an alkaline solution, to obtain the desired final brightness and completely avoid formation and discharge of chlorinated organic compounds.
