    摘要: A sanding station for a belt sanding machine includes at least an endless sanding belt guided over deflection rollers and a pressure segment belt circulating within the sanding belt for pressing the sanding belt against the workpiece. The running direction of the pressure segment belt is oriented transversely to the running direction of the sanding belt.

    摘要: The invention relates to TN and STN displays having very short switching times and good steepness and angular dependence and to the novel nematic liquid crystal mixtures employed therein, which are distinguished by comprising at least one compound of formula IA, where R3 is an alkenyl group having from 2 to 7 C atoms, and comprising at least one compound of formula IB, where R1 and R2 each, independently of one another, are an alkyl, alkoxy or alkenyl group having from 1 to 12 C atoms, with the additional option of 1 or 2 non-adjacent CH2 groups being replaced by —O—, —CH═CH—, —CO—, —OCO— or —COO— in such a way that O atoms are not linked directly to one another, and L is H or F.

    摘要: A magnetic-tape-cassette apparatus includes a loading mechanism with a cassette holder (321, 348) which is adapted to lift the magnetic-tape cassette (200) into an ejection position, in which the cassette (200) is inserted and ejected, and to lower the magnetic-tape cassette (200) onto a cassette support (331) in a play position, in which the reel hubs (200e) are engaged by winding spindles (330). The cassette holder (321,348) has a cross-sectionally U-shaped part (321, 348) with two facing holder plates (323, 324, 348a, 348b) and a transverse holder wall (328, 348c) interconnecting the holder plates, the cassette holder (321, 348) being pivotable about a spindle (325) in such a manner that in the ejection position one holder plate (323, 348a) and in the play position the other holder plate (324, 348b) extend substantially parallel to the cassette support (231). In the area of the transverse holder wall (322, 348c) there is provided a supporting ridge (327, 349 a, 354), on which the cassette (200) is supported in the ejection position and is movable while being supported, to lower the cassette (200) into the play position the supporting ridge (327, 348a, 354) is movable away from the cassette (200) to allow the rear wall (200c) of the cassette to be lowered.
