Abstract: The invention concerns a method for an improved oxygen delignification of cellulose pulp with a medium consistency, 8-16%. By pressurisation to a high pressure, greater than 15.0 bar, and by repeated mixing while maintaining the pressure, the fraction of dissolved oxygen can be kept at a high level throughout the complete process, such that a fraction as large as just over 20% of the total amount of oxygen added can be dissolved in the fluid phase, and such that the amount of oxygen in the fluid phase can be maintained at a high level throughout the complete high pressure section. The pressurisation takes place, according to the invention, by at least two pumps arranged in series, where the first pump is an MC pump with a fluidiser and with means of deairing, while subsequent pumps are either MC pumps without deairing or centrifugal pumps, where these subsequent pumps have a pumping efficiency that is at least 10%-20%, higher than that of the first pump. This ensures that the amount of oxygen that is dissolved in the fluid phase and that penetrates the cellulose fibres can be maintained at an optimal high value throughout the process, to give an improved delignification of the cellulose and that pressurisation can take place in an optimal manner.

Abstract: A method for compensating the drift of an element for position measurement mounted on an object, including at least one gyro for measuring rotation of the object about an axis and at least one accelerometer for measuring two mutually perpendicular components of the acceleration of gravity as a consequence of the orientation of the object relative to the acceleration of gravity along two mutually perpendicular directions, which together correspond to the rotation of the object about the axis. The output signal from the accelerometer and the output signal from the gyro are low-pass filtered. These two signals are compared and the output signal from the gyro is compensated using an output signal from the accelerometer so that the deviation of the output signal of the gyro because of drift is decreased or eliminated. The thus produced, compensated signal constitutes an output signal from the gyro.

Abstract: A filtering system for the treatment of radioactive fluids, comprising filters with interchangeable filtering elements, positioned within a casing. The casing has a cover and the filter assembly is housed inside a radiation shielding chamber provided with an access opening. At least one opening is provided in the chamber wall opposite the filter which is closed with a removable filter casing cover. The casing cover is shaped to be received in the shielding chamber opening and when in position seals the casing. The cover is also designed to be received by a shielded cask for the transportation of the said filtering element when the spent element is removed and replaced. The filter element is suspended from the cover and hence is removed from the casing simultaneous with the removal of the cover. In the method according to this invention, removal of spent elements is effected without subjecting personnel to high radiation dosage since the filter elements are shielded at all times during removal.

Abstract: In a method of measuring the amount of moisture or water in materials, in particular foods, the material is subjected to the action of a liquiform, organic, hydrophilic water extraction agent and the water content of the extract is determined by mixing the extract and a colour reagent consisting of a transitional metal salt whose metal ion in the presence of anions and the solvent in the extract absorbs a first wavelength of electromagnetic radiation and in the presence of water in addition absorbs a second wavelength of electromagnetic radiation. A decrease in solvent concentration in relation to the anion concentration brings about reduced absorption of the first wavelength. A sample of the reagent- treated extract at a predetermined, substantially constant temperature is transilluminated with electromagnetic radiation of the first wavelength, and an optical characteristic of the sample is measured and related to predetermined data which correlate different water contents in the extraction agent with said optical characteristic. The transitional metal salt may be a cobalt salt, and the first wavelength may be 655 nm. Extracts of chloride-containing sample materials are preferably saturated with chloride before measurement of the optical property or magnitude.

Abstract: The protective arrangement is for a series condenser battery (C1-C5) in a high voltage mains (L), and comprises a voltage-dependent resistance (R1) in parallel with the condenser, a triggered spark gap (G1,G2) parallel to the resistance and shunting it when overload occurs, and an energy absorption detector (CU) which to prevent resistance overload produces a trigger signal for the spark gap. A pulse transformer (TR) produces the high voltage trigger pulses, and the low voltage side of the transformers is in series with a normally open coupling component (T1,T2) connected to a unit (C5) in the condenser battery (C1-C5). The signal from the detector for triggering the spark gap is fed to the coupling component to close it. A sensor (IT)probes the current through the resistance, and provides a signal (i) to the energy absorption detector corresponding to the current, dependent upon wictwhich the detector provides a spark gap trigger signal.
