range of particle sizes to be treated and a higher average pulp density, the invention is distinguished by at least one trans­
versal partition (4) within the container (1) for dividing the container interior into chambers (x,y,z), said partition (4) hav­
ing a central opening (5) for transmission of the liquid mixture between the chambers, and in that the guide means are 
formed as profiles (6a, 6b), mounted on and protruding radially inwardly from the inner wall of the container, which pro­
files in the chamber (y) closest to the outlet end of the container extend parallel to each other and to the longitudinal axis 
of thecontainer, while the profiles in the chamber (x) adjacent to the inlet end of the container from an orientation parallel 
to the longitudinal axis of the container at the container end are progressively curved towards the partition, and air supply 
means (8) furthermore being mounted in each of the chambers (x, y, z).

Abstract: The invention relates to a method for producing a folded seam connection of the joint between two sheet-metal part-shells provided with seaming flanges and forming a workpiece, in particular for producing shell-type silencers (50, 50'), at least one seaming tool and the workpiece, with seaming flanges pressed against one another, being moved relative to one another. The new method is characterised in that - the workpiece is rotated about a workpiece axis of rotation extending through the workpiece essentially perpendicularly to the joint plane, - the folded seam connection is produced by using at least one seaming roller (42, 42') to roll over the seaming flanges one or more times and - the seaming roller (42, 42') is swivelled in the joint plane relative to the workpiece (50-50') or pressed against the said workpiece. The invention furthermore relates to a seaming machine. In the new method and the new seaming machine, there is the possibility of passing over interruptions in the folded seam connection in a simple manner, and for this purpose guidance of the seaming roller is provided by a correspondingly designed guide surface. <IMAGE>

Abstract: The proposed process for the production of energy from renewable raw materials by pyrolysis and/or combustion provides for biomass being preserved in silos (10) by fermentation and being taken from the silo (10) in accordance with the demand for energy production and being processed by two different energy production processes. The starting point for both processes is that the biomass passes through a press (16) where, on the one hand, press juice is obtained which is processed into fermentation ethanol and, on the other hand, a press residue is formed which has been freed of juice to such an extent that it can be fed to a pyrolysis and/or combustion boiler (34) for gasification and combustion. The heat generated therein can be converted into electric power by means of a steam turbine (48) and be used for covering a base load. At peak demand, a gas turbine (56) operated with the ethanol produced can be switched in.

Abstract: In the manufacture of a semiconductor device, both a crystalline area (1 b ) and an amorphous area (1 a ) of a semiconductor layer are exposed to a laser beam (2) or other radiant energy of ultraviolet wavelength in a chemical reactive ambient (3), e.g. of CF₂Br₂. The ultraviolet radiant energy (2) is weakly absorbed in the gas ambient (3) to produce chemically reactive radicals and is strongly absorbed in the semiconductor layer (1 a ,1 b ) to heat directly the amorphous area (1 a ) more strongly than the crystalline area (1 b ). In this manner the amorphous area (1 a ) is chemically etched preferentially with respect of the crystalline area (1 b ) which may be used to form an emitter region or other active area of the semiconductor device. Preferably the amorphous area (1 a ) is formed on an insulating layer (4 and 5) with the crystalline area (1 b ) in a window on a monocrystalline substrate (6). The insulating layer (4 and 5) provides a thermal barrier below the heated amorphous area (1 a ) of the semiconductor layer, and because the insulating layer is not heated by the ultraviolet energy (2) it protects the underlying substrate (6) against degradation by heating.
