Abstract: The present invention relates to preventing and/or treating urologic diseases and symptoms in humans or domestic animals. The present invention relates also to preventing and/or treating pain in the pelvic area. The invention relates to use of a heteropolysaccharide composition isolated from ligneous plants and comprising hemicelluloses, mainly glucomannans, but also xylans and pectic polysaccharides, as well as fractions, subgroups or mixtures of these, as pharmaceutical preparations, food additives and food products.

Abstract: A hydrophobisation composition, which includes a hydrophobisation extract obtained by extracting outer bark of birch in an organic and/or polar solvent and which includes at least 30 weight-% betulinol. Also disclosed is a method for hydrophobisation of a surface, which includes steps of applying a layer of hydrophobisation composition containing betulinol on a surface of a substrate, and drying and heat-treating the layer of hydrophobisation composition. A substrate having a surface which is hydrophobised by using the method is also disclosed.

Abstract: The use of i) finely divided knotwood, or ii) an extract, obtained by extracting knotwood with a polar solvent and recovering the extract, as an antioxidative agent. A fraction of the extract may also be used as an antioxidative agent.

Abstract: The present invention relates to a method for treating pectin-containing ligno-cellulosic raw materials in a high-yield pulping process utilizing one or more treatment stages at alkaline conditions. The invention provides a method for controlling the alkaline treatment step, wherein the alkali is applied at a low temperature treatment stage before one or more consecutive treatment stages at the same or higher temperature. The present invention also provides pulp, paper, board or tissue obtained with said method.

Abstract: The present invention relates to a method for isolating of phenolic substances or juvabiones from wood comprising knotwood, said method comprising the steps of

Abstract: A method for recovery of branch knot wood and/or normal wood from oversize chips in which the oversize chips are ground to splinter, which then is dried and mixed with water, and then the sedimented splinter containing high concentrations of extractive substances and having a high specific weight is recovered and extracted in order to recover valuable extractive substances, particularly lignans. The lighter splinter floating up to the water surface is recovered in order to recover normal wood material for the pulp production.

Abstract: A method and apparatus act on a sample liquid of a pulp and paper industry process water, such as a pulp slurry or white water. The sample is acted upon in an apparatus including sample flow chamber, a filtrate flow chamber, and a filter connecting the sample flow chamber with the filtrate flow chamber. A flow sample liquid, including solid substances such as fibers and filler materials (as well as dissolved and colloidal substances) is introduced through an inlet into the sample flow chamber. A main flow of the sample liquid is discharged through an outlet. A flow of filtrate is passed through a filter from the sample flow chamber into the filter flow chamber, thereby separating a predetermined fraction of solid substance from a minor portion of the introduced flow of sample liquid, in the filter. The minor portion of sample liquid corresponds to less than 1%, typically less than 0.1%, of the total introduced flow of sample liquid.

Abstract: This invention relates to a method for the recovery of organic substances dissolved or brought into a colloid form during the manufacture of a mechanical pulp where said mechanical pulp has not been subject to previous alkaline bleaching or other previous process carried out under alkaline conditions. The method is characterized in the deacetylation of the galactoglucomannans having been brought into dissolved or colloidal form during the pulping process, and subsequent deposition of said deacetylated glucomannans onto a solid phase, such as pulp fibers or organic or inorganic additives. The deacetylation is performed either by alkali or enzymatically. The method diminishes the organic substance loading on recycling waters and effluents, and improves the yield and strength properties of the pulp.

Abstract: A method for refining of soaps, in which method the unsaponifiable neutral substances included in the soap are separated by means of extraction from an aqueous solution containing low molecular weight ketones by water immiscible organic solvents, whereby an organic phase is obtained that contains unsaponifiable neutral substances, and a water phase that contains mainly salts of fatty acids and rosin acids, which phases are separated and processed in a way in itself known, whereby neutral substances and, correspondingly, a crude oil with a high content of free fatty and other acids and, consequently with a high acid number, are obtained.
