Abstract: A device is described for aeration of the hypolimnion in stagnant waters, which device is equipped with a rising tube, falling tube and transfer chamber connecting the rising tube and falling tube. The transfer chamber is incorporated in a floating platform. The rising tube and the falling tube are designed as floats which can be flooded and emptied, which can be suspended from the floating platform with essentially horizontal tube axes. The rising tube and the falling tube can be connected via detachable couplings to connection branches of the transfer chambers prior to pivoting from the horizontal floating position into a vertical operating position, this operating position being set by flooding the floats. <IMAGE>

Abstract: The present invention relates to a method and a means for charging liquid slag to a closed smelting furnace. The means for charging liquid slag comprises a double walled tube extending through an opening in the furnace roof, said tube being connected to means for raising and lowering the tube relatively to the furnace roof. Means for gas tight sealing are provided between the furnace roof and the double walled tube. A funnel shaped part is secured to the upper end of the tube, said funnel shaped part being equipped with a closeable lid for gas tight closing of the funnel shaped part. For charging of liquid slag to the furnace the tube is lowered down into the furnace to such an extent that the lower end of the tube is under the slag level in the furnace, whereafter the lid is opened and liquid slag is charged into the furnace. When charging of liquid slag is finished, the lid is closed and the tube is raised to such an extent that the lower end of the tube is above the slag level in the furnace. For cooling the tube a cooling medium with a boiling point below the slag temperature in the furnace is provided between the double walls of the tube. The cooling media will start to evaporate when the lower end of the tube is under the slag level in the furnace. The vapor is condensed in the funnel shaped part and condensed cooling medium is returned.

Abstract: An apparatus for pressing and steam curing a wood-particle mat to produce a wood-particle board includes a pair of pressing belts which are arranged above each other at a distance to define a gap therebetween within which the wood-particle mat is conveyed and shaped. Along its passage through the pressing belts, the wood-particle mat is first moved along a compression zone in which the gap is gradually reduced and then passes along a sizing zone. Cooperating with the pressing is a steam injection unit which includes a steam supply channel system and a steam discharge channel system. Both channel systems border on the pressing gap and are provided with nozzle bores extending towards the gap. Via the supply channel system, steam is injected along the compression zone in direction of the wood-particle mat while the discharge channel system which extends at least along a downstream section of the sizing zone is provided to collect and eventually to discharge steam.

Abstract: The present invention provides a novel apparatus for computing products in Galois fields GF(p<m>) with emphasis on the case p = 2. The elements of the field are represented in polynomial basis and no basis conversion is required. The apparatus consists of two distinct subunits. The first subunit simultaneously produces the first m alpha -multiples of one of the two elements to be multiplied. The second subunit simultaneously produces the m inner products of the second element and the m vectors consisting of suitable components of the above mentioned  alpha -multiples. Both subunits are capable of operating over any Galois field GF(p<m>) where m is an integer in the range [2, M]. Consequently, the apparatus is programmable for operation over any of the above mentioned Galois fields.
