Abstract: Spreader roll for a fabric in a paper machine, the spreader roll being supported at the middle of thereof and comprising an inner tube and an outer tube attached onto the inner tube through an intermediate part. The inner tube and the outer tube are substantially coaxial with one another when the roll is in an unbent state. Annular intermediate spaces are situated between the tubular parts at both sides of the intermediate part, the intermediate spaces being dimensioned so they permit deflection of the inner tube and the outer tube relative to one another when the fabric passing over the roll is being tensioned. Ends or end flanges are situated at the outer end of the inner tube, along with axle journals. The double mantle of the roll with the intermediate part thereof is composed of a piece of reinforced plastic made as a substantially single, unified piece, in which the outer tube and the inner tube are integrally connected through the intermediate portion, without joints. The double mantle of the spreader roll with the intermediate part thereof is made, e.g., of epoxy plastic reinforced with carbon fibre. Moreover, a method is provided for the manufacture of the spreader roll.

Abstract: A bioreactor comprising a bioreactor tank, a plurality of transparent cylindrical bodies together making up a light radiator and arranged parallel to each other in the bioreactor tank, a plurality of optical conductors inserted into each of the transparent cylindrical bodies, a light source device for guiding into the optical conductors the visible light ray components of solar rays and/or artificial light rays, and a gas-exchanger for supplying carbon dioxide CO2 to a micro-organisms suspension in the space between the transparent cylindrical bodies in the bioreactor. A part of the micro-organisms suspension in the bioreactor is returned to the bioreactor through the gas-exchanger, and carbon dioxide CO2 is supplied to the micro-organisms suspension in the gas-exchanger. The gas-exchanger consists of silicone pipes having microscopic holes through which the returned micro-organisms suspension pass and a hermetically sealed tank into which the silicone pipes are disposed. Carbon dioxide CO2 at a pressure higher than that of the micro-organisms suspension flows into the silicone pipes upon being supplied to the hermetically sealed tank.

Abstract: This invention concerns a feeding wheel for the use in wood processors and wood harvesters for the feeding of wood trunks (6) past debranching knives (7). The feeder wheel comprises an inner steel cylinder (2) provided with an outer thick layer or mantle (3) of polyurethan rubber that is vulcanized to the steel cylinder (2). Radial holes (4) are arranged extending through the supporting steel cylinder and the elastic layer. The holes have the same diameter all through and allow juice, bark parts and other debris to fall through the wheel so that it can not serve as a lubricant and thus the grip of the wheel (1) is increased. Alternatively the holes can be used for the fastening of grip increasing metal means floating in the holes so that they can be pushed into the elastic material, and thereby not impairing the quality of the tree.

Abstract: The present invention concerns a floatation clarifying/flocculating procedure for purifying liquid, in which particles of impurities present in a liquid to be purified or impurities dissolved in the liquid which have been converted into particle form with the aid of flocculating chemicals, are separated from the liquid to be purified and carried to the surface of the liquid, to form thereon a sludge bed. The sludge bed is conducted out through a sludge trough to a sewer or equivalent, and flocculating chemicals are then added to the remaining liquid thus already at least partially purified, so that the chemicals form dirt particles with the impurities still present in a dissolved state but which have not yet been removed from the remaining liquid. The liquid or water flocculated in this manner is conducted out through a discharge aperture and towards and additional clarifying procedure in which the dirt particles are separated and the thus-purified liquid can be taken into use or conducted back into the environment as regarding, e.g., residual waters. Floatation clarifying and flocculating are performed in the same floatation clarifying/flocculating basin. The present invention is also directed to the device for carrying out this floatation clarifying/flocculating in a single basin.

Abstract: The invention is a method for cleaning bearing steel that primarily consists of carbon, silicon, manganese, phosphorus, sulphur, chrome, aluminium, oxygen, nitrogen and titanium, with the remainder being iron together with impurities. The bearing steel is smelted in a smelting furnace in order to clean the steel through oxidation. The smelted steel is then poured into a separate container, phosphorus is removed from the smelted steel and oxide-containing slag that flows on top of the smelted steel is absorbed and removed with a vacuum slag cleaner. Reducing cleaning of the steel is then carried out through forceful stirring of the smelted steel in the presence of a high degree of basic slag, which has a basicity of at least 3, while at the same time the temperature of the steel bath is adjusted. Said cleaning is carried out in an indifferent atmosphere which is under a pressure greater than normal pressure. Vacuum extraction of the steel is carried out by means of a vacuum extraction circulation device that generates powerful circulation for 2/3 of the processing time and weak circulation for 1/3 of the processing time. Finally, there is a reduction cleaning of the steel through gentle stirring of the smelted steel in a reducing atmosphere at normal pressure. Said process reduces the amount of phosphorus, sulphur, aluminium, oxygen, nitrogen and titanium to no more than 0.01 percent, 0.002 percent, 0.015 percent, 0.0006 percent, 0.005 percent and 0.0015 percent, respectively (all calculated in percent by weight).

Abstract: A process and an apparatus for flow rate measurement are based on the utilization of a measuring body exposed to the medium, the flow of which is to be measured, a physical quantity of said measuring body, for instance the resistance, changing with the temperature. The quantity (R1, R2) of the measuring body is measured in a measurement sequence at least two times during the cooling or heating of the measuring body, the time interval between the measurements being known or the same. Furthermore, the quantity (R0) of the measuring body is measured before heating or after cooling, i.e. when the measuring body has substantially the same temperature as the medium flow. Finally, the flow rate is calculated on the basis of the measurement values (R0, R1, R2) and the time interval (between R1 and R2). At least three quantity measurements are instead carried out with a known or the same time interval according to an alternative during heating or cooling and the flow rate is calculated on the basis thereof.

Abstract: The present invention relates to a method and a device for aligning shaft sections at a shaft (7) consisting of several parts with the shaft sections joined by means of couplings (A-D) and the shaft journalled in bearings (1-6) on each side of the couplings. Strain gauges (11, 12) are fixed to each side of each coupling. Measured values indicating the strain at each shaft coupling are transmitted to a unit (EVAL) which evaluates the bending moment in the centre of the respective coupling. The bending moment values for each coupling section are then utilized in a moment minimization unit (MINMOM) and/or a third unit (LAZY) which utilizes indications of allowed angular deviations for each coupling to minimize the bearing movements which have to be made to get the angular deviations of all the couplings (A-D) within given tolerances.
