Abstract: Transport system with a transport track (1) along which one or more transport elements (2) (cabins) are moveable, said track (1) running over a substantial horizontal distance, and at least two horizontally spaced stations, for loading and unloading persons and/or goods from the cabin, said stations being at a different vertical level of at least several meters, and the transport track brigdes the said level difference through a relatively steep course and preferably the transport track (1) and/or the cabin are mutually adapted such that the passenger comfort is secured along the part of the track where the level difference is bridged.

Abstract: A process for preparing organosiloxane block copolymers which comprises reacting (a) an organopolysiloxane containing Si-bonded hydroxyl groups and having an average molecular weight of at least 800 g/mole, in which at least 80 mole percent of the units are siloxane units, and one valence of each silicon atom is satisfied by an SiC-bonded organic radical, while the remaining silicon valences are satisfied by siloxane oxygen atoms or hydroxyl groups, with (b) a diorganopolysiloxane having one Si-bonded hydroxyl group in each terminal unit and an average of at least 10 silicon atoms per molecule in the presence of (c) an organic solvent and (d) an alkali metal carbonate and/or an alkali metal carboxylate to form an organosiloxane block copolymer.
