  • Publication number: 20130122529
    Abstract: A method for diagnosing or predicting the risk of developing preeclampsia by measuring the level of A1 M and one or more of the compounds HbA, HbF in a sample and comparing the obtained values with reference values. By using a combination of information relating to A1 M and HbF improved diagnose or prediction is observed.

  • Patent number: 6668600
    Abstract: A device for washing and dewatering a fiber pulp suspension. The device has two hollow, circular-cylindrical screen members that contain evacuation chambers for conducting away liquid. The screen members rotate towards each other for the purpose of forming a nip. At least one of the screen members is arranged in a trough which partially encloses the casing and which converges towards the casing in the direction of rotation of the screen member. At least one pulp inlet box is arranged at the highest point of the screen members for the purpose of introducing pulp between the casing the trough. The pulp inlet box is provided with a pressure equalization section in which a certain equalization of irregularities in pulp qualities takes place before the pulp is fed into the actual washing or dewatering gap.

  • Patent number: 6631810
    Abstract: The arrangement is for washing and dewatering a fiber pulp suspension. The arrangement comprises two hollow, circular-cylindrical screen members that have evacuation chambers arranged inside the screen members for leading off liquid. The screen members rotate counter to each other to form a nip. At least one of the screen members is arranged in a trough that partially encloses the jacket of the screen member and, in the direction of rotation of the screen member, converges towards the jacket of the screen member. A sealing arrangement for a pulp head box distributes the pulp onto the jacket surface of the screen members. By forming a progressively decreasing gap B-A at the pulp head box counter to the rotation of the screen member, a simple self-sealing of the pulp suspension can be obtained which allows fiber residues to be returned to the dewatering zone.

  • Patent number: 6604743
    Abstract: The replaceable wearing surface is for a sealing arrangement on drum end walls on a press drum that de-waters fiber suspensions radially into the drum through the shell of the drum. The wearing surface of the sealing arrangement has a wear ring and holder members. The wear ring is, on a side that faces into the drum from the drum end-wall, provided with locking members. The locking members are arranged parallel to the drum axis and are preferably in the form of knob-shaped locking members. The arms of the holder members are designed to engage the locking members. The holder members are fastened to the drum end wall by suitable fixing members.

  • Patent number: 6521094
    Abstract: Device for the washing and dewatering a fibrous suspension, which device incorporates two hollow, circular cylindrical filter drums (1), which filter drums incorporate evacuation chambers inside the filter drums for evacuation of fluid. The filter drums rotate in opposite directions to create a pinch (2) where at least one of the said filter drums (1) is installed in a trough (7,8) which partly encloses the outer surface (3) of the filter drum and which, in the direction of rotation of the filter drum, converges towards the outer surface of the filter drum. At least one pulp inflow chamber (4) is installed at the highest point (1) of one or both of the filter drums each equipped with a trough for the introduction of pulp between the outer surfaces (3) of the filter drum and its trough (7,8) for the formation of a fibrous web.

  • Patent number: 6501898
    Abstract: The present invention relates to an arrangement for handling optical fibers in a confined or limited space, such as connecting, reorganizing and/or cross-coupling optical fibers in a cassette without said fibers intersecting one another. By providing the cassette (4) with looping channels (17), the optical fiber cables can be organized in a controlled fashion without needing to cross. The cassette may also include elements (18, 19) which function to change the direction of the optical fibers prior to connecting said fibers.

  • Patent number: 6418265
    Abstract: The present invention relates to an arrangement for handling optical fibers in a confined space, such as connecting, reorganizing and/or cross-connecting several optical fibers contained in optical fiber cables in an insulated space. Controllable organization of the optical fiber cables can be achieved, by providing the insulated space (2, 3) with cable guiding and coiling means. The arrangement includes elastic and tight transits in openings (5, 6). The transits have a tapering centre part and will adapt to optical fiber cables of mutually different diameters and allow the cables to extend in different directions outside the insulated space.

  • Publication number: 20020068566
    Abstract: A telecommunications system has a source base station (BSS) and a destination base station (BSD), and a handover unit (100) having a dynamic offset threshold determination unit (102) which establishes a dynamic offset threshold for starting soft handover. When the dynamic offset threshold for soft handover is exceeded, a preliminary portion of a handover sequence is initiated at the destination base station. The preliminary portion of the handover sequence is initiated so that time-critical handover sequence activities (such as L1 uplink synchronization) are well underway, if not completed, by the time the soft handover is actually needed.
