  • Publication number: 20220316135
    Abstract: The present invention relates to a method for manufacturing modified cellulose fibers for a moldable cellulose fiber based material, said method comprising: a) providing a chemical or semi-chemical wood pulp comprising cellulose fibers, and optionally subjecting the pulp to alkaline extraction to obtain an alkaline extracted pulp; and b) subjecting the pulp or the alkaline extracted pulp of step a) to a chemical treatment with an alkaline solution and/or an organic solvent to obtain a treated pulp or treated alkaline extracted pulp comprising modified cellulose fibers for a moldable cellulose fiber based material. The invention further relates to a moldable cellulose fiber based material comprising at least 70% by dry weight of modified cellulose fibers obtainable by the method.

  • Patent number: 11447370
    Abstract: The invention relates to a method for constructing an elevator comprising constructing a movable machine room in the bottom end of a hoistway formed in a building under construction; and thereafter hoisting the movable machine room; and constructing an elevator car in the bottom end of the hoistway below the movable machine room; and providing a counterweight in the bottom end of the hoistway below the movable machine room; connecting the elevator car and the counterweight with a suspension roping; and thereafter hoisting the movable machine room to a first transport position; and thereafter mounting the movable machine room to the first transport position in the hoistway vertically supported on stationary structures; and thereafter using the elevator car for transporting passengers and/or goods below the movable machine room while the machine room is mounted in said first transport position and the elevator car and the counterweight hang suspended from the machine room by the hoisting roping; and thereafter

  • Publication number: 20220274680
    Abstract: A method and an arrangement for sealing a propeller shaft located under water. The propeller shaft is arranged at a pod of a ship and an air chamber is provided circumferentially around the propeller shaft. The method includes supplying compressed air from a compressed air source to the air chamber, discharging compressed air from the air chamber in an air return line and colleting liquid present in the compressed air discharged from the air chamber in an intermediate leakage tank that is provided in the air return line. The method includes closing the air return line upstream of the intermediate leakage tank, and supplying compressed air to the intermediate leakage tank to effect flowing of liquid present in the intermediate leakage tank to a leakage tank.

  • Patent number: 10814953
    Abstract: The arrangement includes at least one steering electric motor rotating the propulsion unit via a force transmission arrangement. The force transmission arrangement includes a differential including a first shaft connected to the steering electric motor, a second shaft connected to the propulsion unit, and a third shaft connected to a brake device. The third shaft is locked from rotation when a torque produced by an external force on the propulsion unit is below a threshold value, whereby power is distributed only from the steering electric motor to the propulsion unit or vice a versa. The third shaft is allowed to start rotating when the torque produced by the external force on the propulsion unit exceeds the threshold value, whereby power is distributed from the steering electric motor to the rotation of the propulsion unit and to the brake device or from the rotation of the propulsion unit to the steering electric motor and to the brake device.
