摘要： A clothing for a machine for producing or processing a material web has a first and a second woven layer. The clothing has more first longitudinal threads than second longitudinal threads, but the number of first longitudinal threads is at most twice as large as the number of second longitudinal threads. Transverse threads of the second woven layer form contact floats on the machine contact side. Longitudinal threads of the first and second woven layer in each weaving repeat are arranged a first group and a second group. In the first group the longitudinal threads of the first and second layers are arranged precisely one above the other in the thickness direction of the clothing, while in the second group neither of two longitudinal threads of the first layer is arranged precisely above a single longitudinal thread of the second woven layer in the thickness direction of the clothing.

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 structuring fabric for use in a machine to produce a structured fiber web, such as a structured tissue fiber web, has a machine direction, a cross machine direction, and a thickness direction. The structuring fabric includes a woven base fabric with a web facing side and a machine side. A plurality of structuring beads of polymeric material are formed on the web facing side of the woven base fabric, the structuring beads being suitable to provide a visible structure to the fiber web that is produced on the structuring fabric. The structuring beads rest on an upper foundation surface of corresponding sublayer beads of polymeric material. The sublayer beads thereby provide a foundation for the structuring beads. There is also described a production method for producing such a structuring fabric.

摘要： A shoe press roll cover for a machine for producing and/or finishing a fibrous web, such as a paper, card or tissue web, is formed of a matrix material composed of polyurethane, formed essentially from 4,4′-MDI as isocyanate, at least one polyol and at least one crosslinker. The polyurethane matrix material is biobased to an extent of at least 20% by weight. The polyol and the crosslinker are selected from one of several combinations: a) biobased PTMEG as polyol and a mixture of MCDEA and PTMEG as crosslinker; b) polycarbonate as polyol and a mixture of MCDEA and biobased polycarbonate polyol as crosslinker; c) a mixture of biobased polycarbonate polyol and PTMEG as polyol and 1,4-BDO as crosslinker; d) PTMEG as polyol and a mixture of PTMEG and MCDEA as crosslinker, with the 4,4′-MDI in the isocyanate and the PTMEG in the polyol being biobased.

摘要： A woven fabric for a fiber web producing machine has a defined machine direction, a cross machine direction, a web facing side, and a machine side. The web facing side is formed by MD yarns that extend substantially in the machine direction and by CD yarns extending substantially in the cross machine direction of the woven fabric. The MD yarns and CD yarns are interwoven with each other and the woven fabric is configured to structure the fiber web produced on the woven fabric. A plurality of adjacent long flotations of MD yarns on the web facing side form together a discrete element that is raised on the web facing side for allowing the woven fabric to structure the fiber web. The term “long flotation” means that the MD yarn passes over at least six adjacent CD yarns on the web facing side of the woven fabric.

摘要： A method for the state-based maintenance of a coupling arrangement of a track-bound vehicle includes the steps of: providing coupling arrangement data and surroundings data; transmitting the coupling arrangement data and/or the surroundings data to a data processing system and determining a target specification for a maintenance requirement of the coupling arrangement as a function of the coupling arrangement data and the surroundings data; recording images of the coupling arrangement for optical reproduction of an actual state and transmission to the data processing system; and evaluating an optical actual state of the coupling arrangement from the images taking account of the target specification, which is formed from the operating data and the state data, for the maintenance requirement at an evaluation time and taking the evaluating as a basis for correcting the target specification.
