Patent SE-8402596-L (SE)
Inventor: DORCHEUS S H
IPC: D21C9/06
Filed: 1984-05-14
Abstract: Process fluids are transferred by scoops from the sump inside the rotatable drum to a higher elevation, which is outside the drum and normally at the centreline of the drum. The scoops extend longitudinally within the drum and rotate as the drum rotates from the sump position to an elevated discharge position. Each scoop has an imperforate trough with sloping bottom or baffle which moves with the drums rotation. An open fluid outlet at the hub or rotative axis of the drum is in communication with one edge of the baffle such that when the scoop moves to the discharge position, fluid flows along the baffle and out of the drum through the hub. The device is partic. useful as a washer for pulp and paper stock pulps. It is energy conserving as it operates without vacuum equipment or pumping to remove the fluid from within, to a higher site outside the drum. Once outside the drum the fluid may flow by gravity into an identical second unit to be used as wash liquor.

Abstract: In a worm gear with a worm screw (1) and a worm wheel (2), the self-locking is achieved by the worm screw (1) being axially displaceable on a shaft (4). A driver (11) on the shaft (4) is arranged in a rhomboidal recess in a sleeve (5), on which the worm screw (1) is fastened. During driving of the shaft (4), the driver (11) is displaced into a corner of the recess, the sleeve (5) and the worm screw (1) being displaced axially into a central position so that the friction surfaces (6, 8 and 7, 9) run freely thereon and on a fixed machine part (10). When the shaft (4) is not driven, a reaction moment which acts on the worm screw (1) and is caused by a torque of the worm wheel (2) has the effect that a pair of the friction surfaces (6, 8) or (7, 9) comes into contact and brakes the worm screw (1), as a result of which self-locking is achieved. <IMAGE>

Abstract: In the stepwise feeding of a packing material web for the application of cover strips over prepunched pouring openings, the pouring opening is sensed by means of a photocell which is located as long before the point of application as the distance between two pouring openings. Any errors in this distance will thus affect the accuracy of application. In order to avoid this it is proposed in accordance with the invention to sense the passage of the actual pouring opening and start a countdown sequence, at the end of which the web feed is interrupted with the pouring opening in correct position for the application of the cover strip. An arrangement for the realization of this, seen in the direction of feed of the material web (1),comprises a sensing device (4), a processing device (5) and a forward feeding device (9) which are connected to a control unit (13)

Abstract: The invention relates to a method and apparatus for theorem checking with the intention in so-called tautology checks of establishing whether or not all possible attributions of the truth values (0 and 1) to variables in a boolean formula render the formula true. The problem of known techniques is that checking of the truth content is effected against all variables in an original formula, which requires many calculations to be made and which is highly time-consuming. According to the invention, an original formula is divided into part-expressions, so-called triplets, each corresponding to a part-formula of the original formula, whereafter logic 0:s and 1:s are instantiated (allotted) to variables in the triplets for the purpose of checking the truth content. The check is thus made against triplets instead of against all variables in the original formula, therewith greatly reducing the number of calculations necessary and providing a considerable saving in time. Apparatus, called a theorem checker, for carrying out the method includes a sequence unit for controlling the calculation sequency, a generator G for generating sequences of ordered variables, a permanent unit P for storing triplets, a plurality of arithmetical units, evaluators (E) and an analyzer A operative to analyze the result obtain from all calculations.

Abstract: A method for detecting a flag in connection with random access in a time divided mobile radio system, for instance, an FDMA/TDMA system, which includes digital traffic channels and control channels which are organized so that four traffic channels (TC) and two control channels (CC) are included in a TDMA-frame. A base station (BS) transmits continuously flags (B/I, R/N, R/F) in the time slots (1, 4) of the control channels. According to the invention, different numbers of binary values are assigned to the different states of one flag. A state (B) in a flag (B/I) which is particularly senstitive to errors in the transmission is given a greater number of binary values than the other state (I), whereby a secure detection of the flag is achieved. <IMAGE>

Abstract: A method for treatment of one or more wood elements by pressurization comprises the steps embedding the wood elements into a pressure medium, of increasing the pressure in the pressure medium, whereby the wood element is compressed by transmitting the pressure via the pressure medium to the wood elements, and of reducing the pressure in the pressure medium, whereby the wood element is relieved. During the treatment, liquid present in the wood elements is driven out therefrom. The pressure medium comprises a plurality of solid bodies with intermediate spaces. The solid bodies transmit the pressure to the wood elements such that a pressure difference arises between the wood elements and said spaces, which pressure difference drives out the liquid. During the relief phase, the wood elements substantially resume their original shape. The method can also be used for introducing impregnating liquid into the wood elements after the liquid expulsion.

Abstract: A method for treating sludge from wastewater purification is described. In the method, a sludge is treated, which contains phosphorus and at least one metal which originates from precipitation chemicals and which is selected among divalent iron and aluminum, the pH of the sludge being adjusted to below 4, preferably below 2, for dissolving the content of the phosphorus and said metal in the sludge; the remaining sludge is separated; the solution relieved of sludge and containing phosphorus and said metal is treated for precipitation of the phosphorus content of the solution as FePO4 at a pH of 2-3; and precipitated FePO4 is separated. The method is characterized in that the solution which remains after separation of FePO4 and which contains said metal from the precipitation chemicals, is recycled to the wastewater purification. The phosphorus content of the solution is precipitated as FePO4 by adding an at least equivalent amount of Fe3-.

Abstract: The invention relates to a method for cutting a log into pieces. The log is cut into pieces with at least two nearly diametrical cuts (S1, S2), where the outermost lie essentially symmetrically around the pith of the stock. Each so-obtained plank is edged (S7, S8) with the outer side as a reference for the trimming direction. Two planks are formed through a cut (S9, S10) being placed near to the pith essentially parallel with each edged outer side. The cutting is performed on the outermost part of the log with the alignment cut (S3, S4) essentially parallel with the nearly diametrical cuts (S1, S2) preferably in the same operation as the cutting into pieces with the nearly diametrical cuts. Each block with the alignment cut (S3, S4) is conveyed through at least one twin-bladed saw, the cuts of which are inclined with respect to the base surface of the block, for example 30° and cut essentially radially symmetrically around the position of the pith. This can be performed twice with different inclinations in a twin-bladed saw.
