The present invention relates to a system for the conversion of chemical structures where the system contains a reservoir reactor having a first lower zone where high solubility of at least one salt in a solvent is maintained under first conditions of pressure and temperature, a second upper zone for precipitating at least one salt under second conditions of pressure and temperature, means for maintaining the first and second conditions of temperature and pressure, means for generating ultrasound, and means for forming a solvent in the lower part of the reservoir reactor.

The present invention relates to a process for converting chemical structures, that is to say a process for the conducting of chemical reactions in a fluid under pressure and at temperature in a supercritical fluid in particular, containing a solvent and at least one electrolyte such as a salt, in which reactive species are generated in situ by electrolysis. According to the invention, the fluid flows upwards in a reservoir reactor crossing through a first lower electrolysis zone with high salt solubility and a second upper zone in which the salts precipitate, then the fluid free of salt is evacuated at the upper part of said reservoir reactor and directed into a second tubular reactor to reach the desired stage of advancement of the conversion.

A process and a device for the continuous chipping of timbers of different length. To increase the chipping performance, in the execution of the sawing cut or directly thereafter, at least one supporting element for supporting the leading end face of a long timber pack and the posterior end face of a short timber pack is directed into the sawing plane. Directly adjoining the short timber pack, a just sawn-off short timber pack, together with the supporting element enclosed between them, is conveyed forward by one advancement cycle in the same direction. The supporting element, following the conclusion of the advancement cycle, is conveyed back into the directing-in area of the sawing plane, and each short timber pack is supportingly transported, free from any structural distortion, up to the chipping tool.

A method and apparatus for setting the knife projection of regrindable, strip-shaped cutting tools which are each screwed releasably to a knife carrier (8) and which are releasably arranged together with the carrier, in an at least approximately radial direction, in the rotary-drivable disk (1) of a disk-type cutter. To simplify the operation and to improve the chip quality: first, each knife (4) of the disk (1) is set outside the disk-type cutter, in a single setting device, to a respective identical distance between the cutting edge (10) and the inner longitudinal edge (11) of the knife carrier (8) and is then screwed firmly to the associated knife carrier (8); second, after being installed in the disk (1), the knives (4) are successively oriented and fixed relative to a common plane (39) which is perpendicular to the disk axis (5) and which defines the first-cut face of the wood during the cutting (cutting plane); and third, the knife adjustment is carried out in such a way that the knife projection of each cutting edge ( 10) relative to the flight circle of the disk surface (3) increases outward in the radial direction over the knife length.
