    摘要： Railroad beds require regrading in order to permit for an increased axial load. There are often cables or tubes embedded in the roadbed at the roadbed sides, making regrading difficult. In accordance with the present invention, material is moved by suction to form pits at each side of the track at intervals along the railroad bed, and a laser camera is used to obtain information relating to the profile adjacent to the pits and the positions of the embedded cables or tubes. This information is saved, and used to control a device for mechanically excavating material from the railroad bed sides without damaging the embedded cables or tubes and grading the railroad bed. A laser measuring device is provided for reading the railroad bed profile.

    摘要： Genetically modified lactic acid bacteria having a reduced or lacking or enhanced diacetyl reductase activity, acetoin reductase activity and/or butanediol dehydrogenase activity are provided. Such bacteria are used in starter cultures in the production of food products including dairy products where it is desired to have a high content of diacetyl and for reducing or completely removing diacetyl in beverages including beers, fruit juices and certain types of wine, where the presence of diacetyl is undesired.

    摘要： The invention relates to a hydraulic motor having a motor body comprising a first and a second part (71, 72) which are joined to each other in a parting plane (74). A motor chamber (2) with driving cogwheels (10, 11) is formed by borings (84, 85), which extend from the parting plane into a certain depth in at least one of the first and second parts (71, 72). A by-pass conduit (15) is provided between the inlet and outlet hydraulic conduits of the motor chamber. In the by-pass conduit there is provided a main valve (20) for closing and opening the by-pass conduit for starting and for stopping the hydraulic motor, respectively. The by-pass conduit is formed by portions (16, 17) of a first (100) and a second (101) connection between the parting plane (74) and the inlet conduit (5), and between the parting plane (74) and the outlet conduit (7), respectively, and by a cross link (18) between the first and second connections (100, 101).

    摘要： A device in connection with a hand-operated working machine with a water flow directed to the working tool comprises a first control which is a control (15) for a drive motor (3) for the tool, and a second control which is a control (17) for the water supply to the tool. A water control valve (45) in a water supply conduit (14) can be adjusted to adopt chosen opening positions, and is arranged constantly to be kept open in any chosen opening position when the motor is running the tool under influence of the drive motor control. The chosen opening positions are adjustable, i.e. the through opening of the valve can be increased or decreased by using water supply control (17).
