摘要： A renovation liner is installed in a pipework. More particularly, an end of the renovation liner is closed by an elastic end piece. The renovation liner is impregnated with a hardening impregnating agent. The renovation liner, together with its end piece, is slipped into a position in the pipework to be renovated. A pressure is provided and maintained in a space formed by the renovation liner and the elastic end piece in order to press the renovation liner against walls of the pipework until the impregnating agent of the renovation liner has hardened in shape. The elastic end piece is removed.

摘要： The method is for making an electric motor more efficient by iteratively changing when a processor sends activation signals to transistors to minimize a current required to rotate a rotor at a constant rotational speed. The method is also for changing a rotational direction of the rotor by switching the order in which activation signals are sent to the transistors.

摘要： The method and system enable secure forwarding of a message from a first computer to a second computer via an intermediate computer in a telecommunication network. A message is formed in the first computer or in a computer that is served by the first computer, and in the latter case, sending the message to the first computer. In the first computer, a secure message is then formed by giving the message a unique identity and a destination address. The message is sent from the first computer to the intermediate computer after which the destination address and the unique identity are used to find an address to the second computer. The current destination address is substituted with the found address to the second computer, and the unique identity is substituted with another unique identity. Then the message is forwarded to the second computer.

摘要： The method is for the preparation of kraft pulp with increased pulping yield from lignin-containing cellulosic material using polysulfide cooking liquor. In order to increase carbohydrate stabilization and hence the yield from a kraft cooking process a first impregnation stage using polysulfide cooking liquor is implemented at high alkali and polysulfide concentration and at a low temperature. Knots are added to a high-pressure conduit extending between an impregnation vessel and a digester.

摘要： The improved method and arrangement are for cooling torrefied lignocellulosic material. By adding water in controlled amounts to the torrefied material in a grinder at exit from a roaster the entire volume of torrefied material could be cooled down to a temperature well below the critical temperature without increasing the water content of the final product.

摘要： The invention relates to an improved design of the bottom of a continuous digester reducing the torque load on conventional bottom scrapers with scraper arms arranged at an angle α in relation to the horizontal plane in the range between 5°-30°. A simple digester shell extension VE is installed below the lowermost wash screen WS, ending at a small distance D above the end of the outer end of the scraper arm. The shell extension prevents the descending pulp column from expanding below the wash screen and enables easier shaving action from the scraper, using a dilution and expansion volume established at the outer ends of the scraper arms.

摘要： The method is for sharpening a blade. An automatic sharpening apparatus is provided that has a holder. A blade is placed into the holder. A grinding-wheel driving motor, in operative engagement with a wheel on a spindle, rotates a grinding wheel. A grinding assembly motor moves the grinding wheel in an x-direction towards the blade. A linear motor moves the grinding wheel from a first position to a second position in a z-direction without moving the grinding-wheel driving motor. The rotating grinding wheel engages the blade. The grinding wheel sharpens the blade.

摘要： The method is for separation of lignin from original black liquor (BLIN) having the following phases in sequence; a first precipitation phase (PR1) for precipitation of lignin by a first acidification of the original black liquor by adding a first acid or mixture of acids (G1a); followed by a second precipitation phase (PR2) for precipitation of lignin by a further acidification of the original black liquor by adding a second acid or mixture of acids (G1b). The first phase is implemented to lower the pH while avoiding any larger amount of precipitation, i.e. less than 2-5%, while the second phase is implemented in order to obtain the larger part of the precipitation. In total is 40-70% of the total lignin content of the original black liquor precipitated while the residual black liquor after precipitation is still strongly alkaline.

摘要： The method and arrangement is for adding treatment liquor to comminuted cellulose material, preferably wood chips, during the manufacture of chemical pulp in a continuous process. The process uses a down-flow vessel where chips are descending down the vessel in a plug-flow and where treated chips are continuously fed out at the bottom of the vessel. By arranging more than two parallel pipes offset from the center of the vessel a better distribution of treatment liquor is obtained. Any disturbance of the chip plug flow descending down the vessel is reduced to a minimum.
