Abstract: A composition is provided comprising: a) polyvinylchloride, b) inorganic solid particles, and c) a polymer having a polyether segment, wherein at least 60 mol-% of the end groups of the polymer are selected from the group consisting of carboxylic acid groups and hydroxyl groups, and wherein at least a part of the end groups of the polymer is a carboxylic acid group, wherein the carboxylic acid end groups are linked to the polyether segment via a linking segment comprising an ester group.

Abstract: The invention relates to an automation object (1, 3) which can be connected for data processing to at least one further automation object (1, 3). The automation object (1. 3) has an object-specific information item, it being possible to transfer this object-specific information item to the further automation object (1, 3). The object-specific information is present in a metalanguage or in a form which can be converted into a metalanguage.

Abstract: An X-ray tube (40) including a rotary anode (44) a cathode (1) and compact shielding means (5) for effective shielding against undesired secondary radiation. The secondary radiation is produced in the vicinity of the emitting surface (11) of a target disk (4) of the rotary anode (44) and comprises both electron and X-ray components. The undesired secondary radiation emanates in a certain limited solid angle from the emitting surface of the target disk. Therefore, in order to optimize the shielding properties of the shielding means (5) the latter are positioned in the direct vicinity of the source of the secondary radiation. In order to intercept the undesired secondary radiation emanating towards the rotation axis (12) of the rotary anode, the latter is equipped with a ring-like projection (7).
