Abstract: The invention relates to a sun protection device having sun protection elements, where each of the sun protection elements have a housing in which a flexible membrane is arranged, where each sun protection element is connected to a reservoir containing a hydraulic fluid by means of a hydraulic line, the reservoir including a solar absorber, where the membrane is adapted to extend from the housing if the pressure in the hydraulic line increases.

Abstract: A gas detector with a selectively adsorbing surface (3) and an acoustic measuring cell (5) is presented. The detector is characterized in that the selectively adsorbing surface (3) and the acoustic measuring cell (5) can be arranged with respect to one another such that gases desorbed by means of thermal desorption from the adsorbing surface (3) reach the acoustic measuring cell (5) and there trigger a pressure wave that can be measured by one or more acoustic pick-ups (13, 14), in particular microphones, which are arranged in the acoustic measuring cell (5). Furthermore, a corresponding method is provided. The detector is particularly suitable for measuring contaminants in interior spaces and ventilation systems.

Abstract: The present invention relates to a polymer material with a functionalised surface and also to a method for in situ functionalisation of polymer materials. Furthermore, the invention comprises the use of the polymer materials.

Abstract: A printing form (10) having a surface (12) of pure silicon or of a silicon ceramic, which bears a pattern composed of hydrophilic and hydrophobic regions, the hydrophilic regions having a first chemical state and the hydrophobic regions having a second chemical state that differs from the first chemical state, in hydrophobic regions, the surface (12) having silicon atoms, to which at least one organic terminal group is attached in each instance. The organic terminal group may be, in particular, an unsubstituted or halogenated aryl terminal group or alkyl terminal group and be attached via an Si—C, Si—O—C or Si—O—Si—C bond. Also a method for modifying the wetting properties of the printing form, the surface (12) being brought into a first chemical state having a first wetting property, and a portion of all regions of the surface (12) being brought into a second chemical state having a second wetting property by modifying the chemical terminal groups of the surface (12).

Abstract: The invention relates to a conveyor device which is used to transport work-pieces, especially the work-pieces of motor vehicle bodies, through a processing area for surface treatment of said work-pieces, comprising a conveyor which brings the work-pieces which are respectively maintained by a holder into the processing area; transports them through said area and removes them therefrom. The inventive conveyor device requires less maintenance in comparison with known conveyor devices. The holders respectively comprise a base part which moves in a translatory movement along a conveyor device and a rotating part on which the work-piece is arranged and which is held in such a way that it is rotatable on the base part. The conveyor comprises at least one drive device enabling at least one directly driven respective holder to be driven directly in a movement along the conveyor device.

Abstract: In order to provide a conveying apparatus for conveying a workpiece, in particular a vehicle body disposed on a workpiece support, from a first position on a first conveying level to a second position on a second conveying level, comprising a conveying carriage, which is movable from a first location associated with the first position of the workpiece to a second location associated with the second position of the workpiece and from the second location to the first location, which apparatus needs a comparatively short cycle time for the operation of conveying a workpiece from the first conveying level to the second conveying level, it is proposed that the conveying carriage comprises a retaining device having at least one retaining element, which is movable relative to the conveying carriage from an operating position, in which the retaining element may act on the workpiece support, into an inoperative position, in which the retaining element is movable past the workpiece support, and from the inoperative pos
