  • Device for transforming chemical structures in a fluid comprising a solvent and salts by ultrasonic action
    Patent number: 6656436
    Abstract: 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.

  • Method for transforming chemical structures in a fluid under pressure and in high temperature
    Patent number: 6551517
    Abstract: 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.

  • Process and device for the continuous chipping of long timbers
    Patent number: 5299610
    Abstract: 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.

  • Method for knife setting in a disk-type cutter and knife mount
    Patent number: 5274899
    Abstract: 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.
