Abstract: A method for producing low lying fog as a special effect, for example in stagecraft, comprises the step of enriching the fog that emerges from a fog machine with water. The fog is wetted with water, mixed and approximately saturated. For this purpose, finely atomized water having a droplet size of 2µ to 10µ can be used. A corresponding device comprises a mixing zone (6), in particular a mixing chamber (7, 13, 20) connected to the fog machine (1), and a fan (2, 11, 19) having a downstream atomizer (3, 12, 18), e.g. an ultrasonic atomizer for water. The fog is mixed with the enriched air stream, if necessary in a counter-current, and reaches the open air as a heavy low lying fog via a water separator (14) and possibly a cooling unit (17).

Abstract: Two segments according to the invention, which form a brush structure created by brush fibres (5a) and plastic rings (1), are joined together by bolts (13) or screws (2) and sleeves (4) with a water-permeable discoid hub (3), in such a way that a separate brush structure can be joined to the segments by stud bolts (11) or similar, to the metal ring (7) of which a plastic ring (G), equipped with brush fibres (5b), is attached for the collection of very heavy oils. For the cleaning of the brush fibres of the segment and the good recovery of the oil being collected, there is a curved metal sheet, preferably on supports, as a continuation of the cleaner, and which forms a casing-like space, preventing the oil flowing off the brushes from returning to the water circulation and improving the collection capacity. The device can be used for the collection of all grades of oil, including very heavy oils. The device is suitable, for instance, for the collection of crude oil with continuously changing properties.
