Abstract: The invention relates to a switch and to a method for transporting and installing such a switch, which is equipped with longitudinal sleepers, the sleeper sections (2, 3) of which are or can be coupled in a flexurally stiff manner by means of a connecting device (16) embedded in the sleeper heads (4) so that the switch can be folded for space-saving transport. The divided longitudinal sleepers are oriented relative to each other and installed in such a way that the joints of the longitudinal sleepers are aligned along a straight line, which thus can serve as a rotational axis for folding up a side of the switch. The joints aligned on the rotational axis act similarly to a hinge band so that complete switch segments, such as a switch end part or the core region, can be folded along the line.

Abstract: The invention relates to a prestressed concrete sleeper, having at least two sleeper sections that can be coupled or are coupled rigidly by a connection device embedded in the sleeper heads, wherein the sleeper sections each comprise a concrete in the region adjacent to the connection device which has a higher rigidity than the concrete in the other regions

Abstract: The invention relates to the use of an absorption liquid for purifying gases from gaseous acidic contaminants, the absorption liquid comprising A) 0.1 to 100% by weight of one or more amines of the formula I where R1 is H, C1-C6-alkyl, an aromatic radical having 6 to 18 carbon atoms or a radical of the formula 2 R2 is H, C1-C6-alkyl, an aromatic radical having 6 to 18 carbon atoms or a radical of the formula 3 R3 is C1-C6-alkyl or an aromatic radical having 6 to 18 carbon atoms R4 is H or CH3 R5 is H or CH3 x is a number from 0 to 3 y is a number from 0 to 3 z is an integer between 1 and 30, and also, if appropriate, B) 0 to 99.9% by weight of water, and/or C) 0 to 99.9% by weight of any desired solvent.

Abstract: A tool magazine system and a gripper for a machining spindle. The gripper is fed to the tool laterally with respect to the rotational or longitudinal axes of the tool, particularly substantially at right angles to the axis, and should grasp the tool.
