Abstract: A filter and a method for filtration is based upon moving a filter surface that is caused to move through a first filtration region (FF) for separation of a prefiltrate and through a second filtration region (KF) for separation of a clear filtrate. A vacuum is applied on the filtrate side of the filtration region (KF). The filtrate region (FF) has two filtration zones (FF1 and FF2) with mutually different pressure conditions. The filtration zone FF1 has atmospheric pressure and the filtration zone FF2 has a pressure that is lower than the pressure of FF1. The pressure change between the filtration zones (FF1 and FF2) occurs in the pre-filtrate region, i.e., before the filter surface has reached the filtrate region (KF).

Abstract: A process for evaporating spent liquor or other waste liquids from cellulose cooking, The evaporation is performed in a multiplicity of evaporators which are coupled in series and in which the evaporation is driven using the liquor steam. The condensates from the steam are divided, in one of more effects, into at least two fractions with respect to purity. The parer fraction from one effect is conveyed, at a high level, into a subsequent effect in the direction of movement of the liquor, while the dirtier fraction is conveyed, at a high level or at the very top, into a preceding effect in the direction of movement of the liquor.

Abstract: In a single-vessel system for continuous cooking of kraft pulp, chips and liquor are conveyed from a high pressure feeder in a transfer line to a first end of a digester. A part of the liquor is separated from the chips that are withdrawn from an outlet defined in an upper part of the digester and conveyed in a return line to the high pressure feeder. A constituent flow of liquor is led from the return line and heated and fed via one or more inlets into the digester at a location that is downstream of the outlet for the return line.

Abstract: The present invention relates to a container for storing and discharging particulate material, in particular pulp chips. For the purpose of preventing bridge formation and making possible a simple and cost-effective design, the container is made so that a positive release is achieved in different transverse directions, after which the material is fed down towards the discharge end 2. The container 1 preferably has a rectangular cross section, with a number of container sections BS1-BS8 in succession from the infeed end 4 of the container to its discharge end 2. Two opposite sides in each container section are given a diverging deflection (5°) relative to the discharge end 2, and the other opposite sides in each container section are given a converging deflection (29°). In following container sections, converging sides change to diverging sides and vice versa, which results in the positive release of the material being achieved alternately with a 90° displacement.

Abstract: The shoe system comprises a shoe that has a toe section and a heel portion. A shoe sole is disposed inside the shoe and has a groove defined therein. The groove extends angularly from an upper surface of the shoe sole rearwardly towards the heel portion of the shoe. A wedge section is removably attached to the shoe sole. A shoe insert has a stiff first member and a resilient second member attached to the first member. The second member is inserted into the groove. The second member has one side that may be thicker than the opposite side so that the second member is only twistable in one direction.

Abstract: The arrangement for shoe wear is for removable attachment of the shoe wear about the user's foot so that the fastening may be achieved by tightening two parts (6, 7) that are separated by a cavity (3) and locked in a tight position. According to the invention, at least one transverse locking part (11) is attached across the cavity. The transverse locking part is attached to the separated parts (6, 7) on each side of the cavity. The transverse locking part is, at least on one side of the cavity, shiftably attached and is movable along the cavity so that the fastening of the shoe wear may occur when the locking part is moved so that the parts are pulled towards one another. The locking part is lockable in different setting positions along the tracks.

Abstract: A method in connection with continuous cooking of chips that comprises impregnating the chips with a impregnation liquid in an impregnation vessel and cooking the impregnated chips in a digester. The impregnation vessel and digester are connected to one another by means of a transfer circulation, which partly, via a feed line feeds the chips from an outlet end of the impregnation vessel to the top of the digester for separation of a free liquid in a separator. The separated liquid from the top of the digester is, partly, via a return line fed to the outlet end of the impregnation vessel for use as a transfer liqid for the impregnated chips to which cooking liquid is added to the chips at the top of the digester. Less than 100%, preferably less than 95%, and more preferred less than 90% of the liquid that is separated from the chips in the transfer circulation is recirculated to the used as transfer liquid.
