Abstract: An arrangement for discharging medium consistency pulp in connection with diffeent pulp treatment devices or apparatuses, the arrangement having a mass chamber, which is arranged between a screw discharging pulp from a pulp treating apparatus and a centrifugal pump transferring the pulp further so that both the screw and the pump are substantially at the same horizontal level with the pulp treatment apparatus. Thus, the presence of a drop leg having a height of several meters is prevented, whereby the centrifugal pump has no need to pump the pulp upwards back to the height of the pulp treatment apparatus.

Abstract: In a loading system for containers, tank vehicles, or other containers that can be flange-mounted to the discharge hopper of a silo, with a tube slide, the inner casing of a double-walled dump pipe that is secured to the discharge hopper is used as a guide for this tube slide. The loading system is arranged beneath this discharge hopper. Apart from the closed position and the dump position, the tube slide can also be locked in a flushing position by means of an operating system. The lower end of the tube slide is configured as an opener for a closing plate of the filler opening of the container or the like that can be closed by the action of a spring.

Abstract: A pressure controlled cutter bit or drill bit retainer in the form of a revolving drill head with hydraulic precision adjustment of the drill bit arranged at a central extension, which is displaceable from its original position by small amounts around a pivot axis by a pressure motor, wherein this displacement occurs without any parts mechanically rubbing against each other and the dimensioning of the pressure motor and extension defining the transmission ratio conditions are selected in such a way that the travel of the drill bit guided along a curved path is greater than the travel of the pressure motor output produced by volume change, and wherein the overall volume of the pressure motor is selected to be slightly greater than the volume required for moving the pressure motor output.

Abstract: Metal reinforcing members (3) are attached by bonding to a surface in the tension zone (1a) of a concrete structure component (1) for reinforcing the component. To prevent the ends of the reinforcing members (3) from separating from the structural component (1) when the component is subjected to load, attachment elements (4) clamp the ends of the reinforcing members against the surface of the component in addition to the bonding action. The attachment elements (4) apply such high compressive forces to the structural component, so that potentially damaging tension and shear forces can not be effective.

Abstract: A process for allowing the attachment of drive or coupling elements, such as cams, gears, crank webs or bearing elements, such as friction bearing bushes, or complete roller bearings on tubes or tubular portions by hydraulic expansion, for the purpose of producing assembled cam shafts, transmission shafts, crank shafts or the like, with the expansion of the tubes taking place exclusively in the region of the respective elements beyond the limit of elasticity of the tubes, against a permanent elastic prestress in the elements. To relieve the load on the seals limiting the regions to be expanded, a counter pressure which is higher than the ambient pressure is applied to the intermediate or end regions.

Abstract: A method is disclosed for the preparation of finely divided, electrically conductive tin(IV) oxide. In a first step tin(IV) oxalate and/or oxalates of polymeric tin(IV) compounds are obtained by electrolysis, in which the anode consists of tin or a tin alloy which contains a doping metal, and the cathode consists of a metal or graphite. The two electrodes are separated by a diaphragm or an organic membrane which is permeable to hydrogen ions and oxalic acid solution is used as electrolyte. Tin(IV) oxide is prepared in the second step by calcining the oxalates obtained from the solution of tin(IV) oxalate and/or oxalates of polymeric tin(IV) compounds, to which known doping agents have been added in conventional amounts.

Abstract: A method for straightening sheet, strips, sections, girders, etc. The method includes measuring the straightening forces of at least one of the straightening rolls in a straightening machine and adjusting the positions of the straightening rolls in accordance with the measured values.

Abstract: The present invention relates to a method and an apparatus for washing pulp according to which method the pulp is supplied onto a movable liquid-pervious support surface to form a substantially continuous layer; and washing liquid is supplied to the pulp layer and passed in several successive washing phases through different areas of the layer in such a way that the washing liquid gradually flows in the opposite direction compared with the flow direction of the pulp layer. According to the invention the washing liquid is divided in two or more partial flows which pass alternately through different washing phases in such a way that the washing liquid which in one phase has passed through the pulp layer flows past at least the washing phase preceding it in the flow direction of the pulp layer. The apparatus of the invention preferably includes a rotating cylinder having a casing surface of which serves as the liquid-pervious support surface for the pulp.
