摘要： A paper machine clothing draw-in device for drawing a paper machine clothing, in particular a drying screen, into a machine designed to produce and/or finish a material web, in particular a fibrous web, such as a paper, board or tissue web. The draw-in device includes a force-distributing element, which is designed to distribute a tensile force, which acts substantially at a point, substantially uniformly along a line. Here, the paper machine clothing draw-in device includes a plurality of such force-distributing elements, which are designed to become or to be connected to each other in normal use.

摘要： A fabric for a web-producing machine, such as a papermaker's machine for producing paper, tissue or board, contains a machine-side and a paper-side. The fabric further contains MD-yarns and CD-yarns interwoven with each other in a predetermined repeat pattern. The MD-yarns 12 have a non-circular cross-section, and a width-to-height aspect ratio of the MD-yarns 12 is greater than 10:1, preferably at least 11:1. Furthermore, a web-producing machine, such as a papermaker's machine for producing paper, tissue or board, contains a fabric of the above described type, where the fabric is preferably applied in a dryer section of the web-producing machine.

摘要： A device dewaters a wet-laid non-woven web formed from a fibrous suspension. The device has a multiplicity of dewatering strips which are disposed so as to be mutually spaced apart. Mutually neighboring dewatering strips conjointly delimit a dewatering gap for discharging liquid from the fibrous suspensions. The device further has at least three format slides which along the longitudinal direction of the respective dewatering gap are disposed or disposable so as to be distributed relative to one another and which partially obscure the dewatering gap in such a manner that any discharging of the liquid by way of the obscured part of the dewatering gap is prevented.

摘要： A method performs shifts in a dog clutch element of a transmission system in a hybrid vehicle. The vehicle has an input shaft being connected to a crankshaft of an internal combustion engine, an output shaft being connected indirectly to driven wheels, an electric machine which is in engagement with the input shaft, and an automatic transmission connected between the input and output shafts. The transmission has a dog clutch element for the releasable coupling of two transmission elements. During a desired shifting of the dog clutch element, the torque of the input shaft is adapted via the electric machine, and therefore a reduced load prevails in the region of the dog clutch element and the latter can be disengaged, after which the internal combustion engine is set to a desired target rotational speed, and after which the dog clutch element is engaged when the target rotational speed is reached.

摘要： A method for controlling a separating clutch in a power train of a vehicle having a drive motor and a retarder. The clutch is arranged such that a rotor of the retarder is switched into a drive connection with the motor and/or power train via the clutch and a working chamber of the retarder can be filled with an operating medium to build up a braking power such that braking torque is exerted by the retarder onto the power train and/or motor. A control system switches the clutch into a closed or an open position. The switching of the clutch into the closed position occurs depending on an input signal to the controller, and the clutch is switched back into the open position depending on essentially no medium being present in the working chamber of the retarder and that predetermined limits of an operating and/or environmental parameter are not exceeded.

摘要： An oil supply system for an automatic transmission or for an automated manual transmission in a drive train. The oil supply system includes an oil sump and a heat exchanger, wherein the oil supply is provided for at least the following operating states of the automatic transmission: a converter mode; a drive mode in one of the mechanical gears; and a retarder mode. To optimize cooling of the oil volume flows in the different operating states two heat exchangers are provided, through which an oil volume flow can be conducted depending on the operating state of the transmission.

摘要： A method for producing an object, wherein the method comprises drying the object or a primary product thereof, the object or a primary product thereof being at least partially dried in at least one drying device, wherein at least one of the at least one drying units contains at least one infrared radiator which is at least partially heated by means of biogas, a combustion gas selected from the group consisting of oxygen, air or other oxygen-containing gases is added to the biogas before said biogas is supplied to the at least one infrared radiator in order to heat said at least one infrared radiator, and the oxygen content in the waste gas resulting from the at least one infrared radiator being heated by means of the biogas is measured by means of a measuring device and the amount of combustion gas added to the biogas.

摘要： An electrical train coupling having two coupling halves, each including at least one electrical contact element, which is electrically contactable with an electrical contact element of the particular other coupling half, including one electrical connection per coupling half. At least one electrical contact element of at least one coupling half is supported by a decoupling element movable against the force of a force accumulator at least also along a coupling direction of the coupling halves, the decoupling element, in a coupled state of the two coupling halves, being moved against the force of the force accumulator into an electrically conductive contact of the electrical contact element with the electrical connection of the coupling half and, in a decoupled state of the two coupling halves, moved by the force of the force accumulator with the electrical contact element, being lifted off of the electrical connection to disconnect the electrically conductive contact to the electrical connection.

摘要： A substrate of a paper machine clothing has a usable region formed with through-channels that are non-cylindrical with a cross-sectional area becoming smaller from an upper side to a middle region of the substrate. An upper rim of at least one of the through-channels directly contacts an upper rim of at least one neighboring through-channel and the upper rims have common local maximum. A sectional plane parallel to the thickness direction of the substrate defines an intersecting line with a sidewall of a neighboring through-channel. The intersecting line has a convexly shaped first portion, a concavely shaped second portion, and a third portion that is again convexly shaped going from the at least one common local maximum toward the middle region of the substrate. There is also described a method of producing such a paper machine clothing.
