Abstract: The invention relates to a blind assembly comprising a blind web (11) which is provided with one respective flexible, flat guide strip (10) along both lateral edge areas. Said guide strip (10) is guided inside a guide along the direction of extension of the blind in order to stretch the blind web. The base of the guide strip (10) is guided parallel to adjacent areas of the blind web. The inventive blind assembly further comprises at least one blind coupling with which at least one of the guide strips engages in a removable, positive manner via an entraining element (12) and via which the guide strip can be extended along with the blind web.

Abstract: Centrifugal separator and a granular bed filter are arranged one over the other in a common cylindrical housing to constitute a unit for separating solid particles from a gas stream. For more effective separation of solid particles within a structure having a given overall volume, the gas inlet pipe is rectangular in cross-section and has a height amounting to 60 to 80% and a width amounting to 20 to 30% of the height H and a gas guide is provided in the gas outlet pipe and extends parallel to the axis of the pipe. This will result in an optimum matching of the separation of solid particles affected by centrifugal force and in the granular bed in close succession in the single structural unit.
