Abstract: Process for the production on metal or plastic surfaces of thin, hydrolysis-resistant, scratch-resistant and stain-resistant coatings, wherein the coating material can be applied directly to the cleaned metal surface and subsequently cross-linked by high-energy radiation, in particular UV radiation. The substrates can be coated in the form of strip and only subsequently brought into the required external shape. Coated substrates such as these are no longer susceptible to staining by food, cleaning agents or fingerprints and can also be rendered antibacterial. Objects coated in this manner are thus suitable for use in architecture, for interior fittings of buildings, in furniture-making as well as for ornamental applications, and in particular in households, in sanitary applications, in hospitals and in the food-processing and pharmaceutical industries.

Abstract: An actuating arrangement for opening and closing a hinged motor vehicle panel has a fluid drive, a control unit, and a sensor unit. The hinged motor vehicle panel is movable between a starting position and an end position, and the control unit evaluates start signals from the sensor unit and stopping the movement of the motor vehicle panel in an intermediate position. The start signals from the sensor unit correspond to current angles of opening of the hinged motor vehicle panel, and predetermined angles of opening of the hinged motor vehicle panel define certain criteria. It is possible to set at least the angle of opening of the intermediate position via the control unit.

Abstract: The invention relates to a hot-top mold for a strand casting apparatus, consisting of a hot-top, which lies on the upper side of a parting agent distributor and presses it with its underside against the surface of a mold, an overhang being formed on the radially inner surface of the hot-top, which protrudes beyond the parting agent distributor in the direction of take off of the strand, the hot-top being centered and held by an outer ring, which is releasably fastened to the mold. The mold surrounds a function ring toward the bearing surface of the mold which, together with the parting agent distributor, forms function surfaces with adjustable roughness on the surfaces. In the parting agent distributor, radial channels are formed at the upper side and the underside, the channel cross sections at the upper side and the underside being in a ratio of 1:3 to 1:5 to one another.

Abstract: The invention relates to a device for filtering and adding grain refining materials to metal melts with a first filter (10) and a feed for a grain-refining material, where the first filter has a porous filter medium. The filter efficiency of the first filter (10) is substantially improved according to the invention by arranging the feed for the grain-refining material in the direction of flow after the first filter (10). The undissolved impurities introduced via the grain-refining material are removed by positioning a second filter (16) in the direction of flow after the feed for the grain-refining material.

The apparatus includes a tub-like having a peripheral wall and a central raised element or cone having tapered outer surfaces, to stabilize the base of the billet during casting and to dislodge the cooled billet as it shrinks.

Abstract: The invention proposes a jet device for a machine for producing a material web, in particular a paper or board web, having a nozzle device for dispensing a jet of liquid which is under pressure and is directed onto the material web and/or a transport belt guiding the material web. A changeover device by which the pressure with which the medium impinges on the transport belt or the material web, respectively, can be set.

Abstract: The invention relates to a device for cleaning a moving transport belt in a papermaking machine, for instance a dry or wet wire belt or a felt belt, having at least one nozzle which can be directed against the transport belt for spraying the woven belt with liquid or gaseous fluid. A suction chamber 18 surrounds and cooperates with the cleaning nozzle (8), so that dirt and/or water mist detached by the nozzle jet (27) from the transport belt (4) or residual water are drawn into the suction chamber (18) and led away, avoiding dirtying or contamination of the nearby area.

Abstract: A control device for a filling-ratio adjusting pump with at least one displacement space works on the suction-throttle principle with a positive variation in volume of the displacement space or displacement spaces and is intended inter alia particularly for common-rail diesel injection systems. It allows an exact, precise and highly dynamic control of the filling-ratio adjusting pump at low outlay, without the system being impaired by undesirable cavitation. Located on the suction side of the pump is at least one throttling 2/2-way valve (21, 21a, 21b; 134; 51, 52, 53, 54; 81; 103) actuated by pressure difference. Either such a 2/2-way valve can be used for a group of displacement spaces or for the entire pump or a respective valve of this type can be inserted in front of each individual displacement space.
