摘要： A hydraulic drive including at least one hydraulic cylinder that includes a piston chamber, an annulus, and a piston that separates the piston chamber from the annulus. The hydraulic drive also includes a first hydraulic pump hydraulically connected with the piston chamber, a second hydraulic pump hydraulically connected with the annulus, a third hydraulic pump, and a directional control valve that has a first switching position and a second switching position. The third hydraulic pump in the first switching position of the directional control valve is hydraulically connected with the piston chamber, and the third hydraulic pump in the second switching position of the directional control valve is not hydraulically connected with the piston chamber.

摘要： A device for producing textile planar structures formed of a plurality of portions deposited beside one another of fiber rovings. A supply device provides a fiber rovings at a transfer installation. A plurality of path guiding rails are disposed beside one another and above the depositing face. A gripper unit and a cutting unit are disposed on each path guiding rail. Each gripper unit and each cutting unit is movable and positionable along the path guiding rail independently of the gripper units and cutting units of the other path guiding rails. The gripper units grab the fiber roving from the transfer installation and move their free end to a desired terminal position. The cutting units severs the rovings at a cutting position. The gripper units and the cutting units have a downholder for pressing the fiber roving against the depositing face.

摘要： A method for regulating output pressure of a hydraulic drive system by using a rotational speed as the actuating variable. The method includes determining a setpoint rotational speed main component of motor drive as a pilot control signal, determining an error rotational speed as a regulating deviation from a comparison of an actual pressure value of the hydraulic drive system and a setpoint pressure value of the hydraulic drive system and adjoining regulating amplifier, adding the determined setpoint rotational speed main component to the determined error rotational speed to create the setpoint rotational speed as the actuating variable, and converting the created setpoint rotational speed into an input rotational speed of the motor drive to drive the hydraulic drive system at the converted rotational speed in order to generate regulated output pressure of the hydraulic drive system which represents actual pressure value.

摘要： A runner for a hydraulic turbine or pump has a plurality of blades. Each of the blades is defined by a pressure surface, an oppositely facing suction surface, a leading edge and a spaced-apart trailing edge. At least one of the blades has a device for supplying a flow of oxygen containing gas to the trailing edge of the same blade. The device includes at least two separate gas inlet apertures and at least two separate gas passages, each extending from one of the separate gas inlet apertures to a separate group of orifices in the trailing edge of the same blade. Each of the separate group of orifices has at least one orifice to admit gas out of the corresponding separate gas passage to the passing fluid during the operation of the runner.

摘要： A method for operating a heating group subsystem of a machine for the production or treatment of a fibrous web. The heating group subsystem includes a first heating group and a last heating group and at least one additional heating group; in each case having at least one device that is heated with pressurized heating steam. Viewed in a direction of travel, the fibrous web is fed first through the first heating group, then through the at least one additional heating group, and thereafter through last heating group. The steam pressure of the heating steam of the at least one additional heating group is adjusted lower than the respective steam pressure of the heating steam of first heating group and of last heating group.

摘要： A method of fabricating a dynamoelectric machine utilizing multi-turn coils includes manufacturing a multi-turn coil having turn and ground insulation and installation of the coil into the stator core of the machine. The loop regions of the coil have no ground insulation during installation and the ground insulation at the loop regions is completed after installation of the coil.

摘要： An actuating drive for a control valve contains a working cylinder which has a piston and a piston rod and forms an actuator for the control valve. The piston bounds a first pressure space and a second pressure space to displace the piston counter to the force of a spring by applying pressure to the first pressure space via a working medium. A working medium circuit is connected to the working cylinder at first and second pressure connections to introduce and evacuate the working medium into/from the first and second pressure spaces. The working medium circuit has a working medium pump connected to convey the working fluid, at a pressure side, to the first pressure connection, and at a suction side, to the second pressure connection. The first pressure space is permanently connected, so as to convey working fluid, to the second pressure space via a bypass line.

摘要： A device for manufacturing fibrous board has a board carrier and a plurality of at least four cutting tools for separating a fibrous material, in particular strand-shaped or tape-shaped fibrous material into portions, and for depositing the portions. The board carrier is displaceable below the depositing cutting tools here through in at least one movement direction. The depositing cutting tools are substantially stationary and are disposed beside one another in such a manner that the portions of these depositing cutting tools may be simultaneously deposited beside one another on the board carrier.

摘要： A method for shifting an automatic transmission, including a drive region, a hydrodynamic converter, an output region, and exactly one planetary gear that acts in a first operating state and a second operating state. In order to shift to different gears of the automatic transmission, different transmission ratios are set in the strictly mechanical power branch by disengaging and engaging clutches and/or brakes in the drive region. The planetary gear set in the output region in the case of at least two different transmission ratios in the strictly mechanical power branch, the rotational movement transmitted by the strictly mechanical power branch is stepped up, in order to always set additional gears.
