摘要:
Shear forces are used for essentially salt-free coagulation of plastics dispersions or rubber dispersions. For this, method of use is made of an apparatus with at least one shearing module which has a stator and a rotor arranged within the stator, where the surfaces facing toward one another in the stator and in the rotor are in each case smooth, or at least the rotor exhibits a structure formed on its surface and facing from this in the direction of the stator, and between the stator and the rotor there is a gap of predetermined gap width. The process is carried out by passing the dispersion to be coagulated through the gap between stator and rotor and precipitating the dispersion by rotation of the rotor with predetermined shear rate and shear deformation.

Luminaire having an optical waveguide plate, which has a first light guiding surface, and having a light reflecting area—arranged opposite the latter—of an opaque reflector, which reflects light back into the optical waveguide plate in such a way that at least part of said light emerges from the second light guiding surface facing away therefrom. The light reflecting area has a very large number of reflecting area regions, which extend obliquely with respect to one another and obliquely with respect to the opposite first light guiding surface of the optical waveguide plate.

The invention relates to compounds of general formula (I); 1a, 1b, 1c and 1d. The invention also relates to a method for the production thereof, pharmaceutical preparations containing said compounds and/or physiologically compatible salts thereof which can be produced therefrom and/or solvates thereof, and to the pharmaceutical use of said compounds, salts or solvates thereof as inhibitors of phosphodiesterase 4. The compounds comprise active ingredients for the treatment of diseases which can have a positive influence by inhibiting the activity of phosphodiesterase 4 and/or TNFα-release, for example, in lymphocytes, eosinophile and basophile granulocytes, macrophages and mastocytes.

摘要:
Plate-type luminaire comprising a prism plate with a smooth upper plate surface and a prism lower surface formed by a plurality of longitudinal ribs; a cover plate made of translucent material resting on the prism surface; and an optical-waveguide plate on the smooth plate surfaces of the prism plate. The plates are curved continuously in the same direction of curvature, transversely to the longitudinal direction of the longitudinal ribs of the prism plate, at least over most of the plate width, with the longitudinal ribs being located on the inside of the arc of curvature of the prism plate. A reflector plate may be disposed over the waveguide plate, with a smooth or a longitudinally ribbed surface.
