Abstract: A multi-stage diffusor (14) leading meridionally into the separation chamber (15) is connected to the pump-like inlet blading (13). For discharging the light parts, recesses (19) which lead into the discharge channels (21) in the inner cylinder are provided at the outlet side end of the inner cylinder (17). If necessary, a collecting groove (20), from which orifices or spit orifices (47) lead to the outside, is provided for the heavy parts, at least upstream of the outlet blading (37). In operation, these orifices are alternately each briefly opened and covered. The stream of the cleaned suspension is taken out via the turbine-like outlet blading (37). At least one part of the inner cylinder (17), in turn bounding the separation chamber (15), can be driven by itself and separately relatively to the outer cylinder (16), so that it can be rotated at a speed of rotation different from that of the outer cylinder (16). It carries at least one scraper (32) which, in operation, clears the inner wall of the outer cylinder in order to prevent caking and to move on the heavy parts. The rotating inner cylinder (17) also carries a pusher ring (44) which revolves in the collecting groove (20), pushes the heavy parts to the spit orifices (47) and alternately closes and clears the spit orifices (47).

Abstract: In a scroll type compressor, a movable scroll (28) is engaged with an immovable scroll (22) so that spaces (30) are formed for taking in a fluid including a lubricating oil mist to be compressed. The movable scroll is revolved around a central axis of the immovable scroll so that, as the spaces are displaced toward a center of the immovable scroll, a volume thereof is reduced to compress the fluid therein. The immovable scroll (22) has a passage (22c) through which each of the spaces is communicated with a discharge chamber (24) upon reaching the center, whereby the compressed fluid is successively discharged through the passage into the chamber. An oil-separating plate (50) is disposed in the chamber at a given level lower than the passage, and a reed valve (23a) is provided at the passage (22c). A retainer (23b) for the reed valve is shaped such that the compressed fluid discharged from the passage (22c) through the reed valve is directed to and impinged on an upper surface of the plate (50), to thereby separate a lubricating oil from fluid, whereby the separated oil is reserved in a lower portion of the chamber defined by the plate, and thus a level of the reserved oil is maintained at the upper surface thereof.

Abstract: The invention relates to a method for linear amplification of a useful signal by means of an amplifier connected to a supply voltage, the useful signal being modulated by a modulation signal of lower frequency. To increase the efficiency of the amplifier whilst retaining the best possible linearity, it is proposed, according to the invention, that the variation with time of the supply voltage, starting from a predetermined minimum below which it must not drop, is corrected in dependence on the modulation signal or on the envelope of the useful signal in such a manner that the amplifier is operated in the linear operating range at smaller signal amplitude values of the modulation signal or of the envelope of the useful signal and is driven into compression at larger signal amplitude values.
