Abstract: Dewatering arrangement adapted to use in a twin-wire dewatering section of a stock processing machine, comprising a single-ply head box (4) for supplying stock through a nozzle (8) with an inlet (11 ) fed by a tube bank (6) with tubes (7) of non-circular cross- section, a closed loop first wire (2) adapted to receive the stock from the head box (4) on its upper surface and with pressure pulse generating blades (5) mounted inside the loop, a closed loop second wire (3) adapted to be fed on top of the first wire (2), and with pressure pulse generating blades (13) mounted inside the loop, thereby pressing the stock between itself and the first wire (2). The inlet height of the headbox nozzle (8), defined as the total tube bank height minus the total upstream thickness of eventual nozzle vanes (14), is at least 150 mm. By using a larger height of the headbox nozzle it is possible to lessen the risk of formation damages and also to use a higher slice opening, without formation disturbances. This in turn also gives better potential for paper strength and formation. The arrangement is suitable to both paper and paper board machines.

Abstract: The present invention relates to a method for manufacturing mechanical or chemi-mechanical pulp by disintegrating and treating wood material. The wood material is defibrated in a first step with a low energy input compared to conventional processes. Then the reject is screened from the defibrated wood material. The reject is then refined separately and mixed again with the rest defibrated material to a final pulp product. The invention also relates to an apparatus for manufacturing mechanical or chemi-mechanical pulp by disintegrating and treating wood based material. The apparatus comprises a defibration device (1) with a low energy input, a screening device (2) separating reject from the main part of the defibrated wood material, a reject refining device (4) and a device for (6) mixing the refined reject with the rest of the wood based material.One object of the invention is to carry out the disintegration and the refining of the pulp in such a manner, that the total energy consumption is substantially reduced relative to common practice.It is a further object of the invention to provide a method and apparatus by which it is easy to control through choice of energy inputs the characteristics of the end product by controlling the properties of the defibrated wood material through the process.

Abstract: The invention relates to a method of determining the concentration of sulfide and optionally also of polysulfide in liquors and solutions of smelt deriving from the sulfate process. According to the method, the concentrations are determined by measuring the light absorption of the liquor or the solution in the ultra-violet range. According to one preferred embodiment, the method is applied to determine the degree of reduction in sulfate liquor and smelt derived from burning liquor, wherein the concentrations of sulfate, thiosulfate and optionally sulfite and/or carbonate are determined by measuring the light absorption of the liquor or the solution in the infrared range, whereafter the degree of reduction is calculated from the measuring data obtained.

Abstract: An arrangement for measuring mechanical properties of foil material (10), preferably paper. The arrangement includes a material excitation unit (12) and a material sensing detection unit (14). The two units are connected electrically to a common arithmetical unit (18). This unit is intended to register and convert electrical signals deriving from the two first mentioned units (12, 14) in a manner to produce final signals which represent the material properties to be measured. The excitation unit (12) includes a laser which, through electromagnetic radiation, is intended to generate in the gaseous atmosphere surrounding the material local transient gas-pressure pulses within variable surface zones which are well-defined geometrically, without the excitation unit coming into contact with the material. These gas pressure pulses cause the material (10) to stretch locally in the boundary regions of the zones, such stretching of the material being necessary to the measuring process. The detection unit (14) senses this stretching of the material, without coming into contact with the material, by detectingtransient changes in these material zones.
