  • Patent number: 4588524
    Abstract: Machine for compacting fuel assemblies, constituted by protective structures containing the fuel and carrying caps at their ends, and for separating the caps from said structures, wherein it comprises a frame forming a lateral bearing surface, a compacting slide block forming a lateral bearing surface facing the first-mentioned bearing surface, a feed opening formed in the frame for introducing an assembly between these surfaces, means for displacing the slide block in a direction perpendicular to these surfaces, two cutting members carried by the slide block and respectively facing the two discharge openings for the caps formed in the frame at the ends of the bearing surface formed thereon, means for displacing the cutting members in said direction in order to separate the caps from the structures, and means for discharging the compacted structure to a discharge opening for the same, formed in the frame.

  • Patent number: 4588507
    Abstract: Electromagnetic filter making it possible to continuously discharge filtration products and a corresponding filtration process.Apart from a conventional filtration section, the filter according to the invention comprises a discharge section and preferably a washing section. A pulsation leg makes it possible to apply to the liquid column a pulsation bringing about a sudden rise of the column and then its slow fall again. Thus, the filtration products are raised and then discharged.Application to the filtration of solutions containing solid products in suspension.

  • Patent number: 4526035
    Abstract: The invention relates to a device for controlling the pressure within a pulsed column. The device comprises first and second dipping tubes respectively issuing into the column at the level of points P.sub.1 and P.sub.2, means for introducing a gas into each of the tubes and for bubbling it in the column liquid and means for determining the pressure difference between said tubes. The first and second dipping tubes respectively issue into the column via cavities C.sub.1 and C.sub.2 having dimensions such that during pressure variations due to pulsation, the gas-liquid interface is always located in each of said cavities and the variations in the gas-liquid interface level in each cavity are inversely proportional to the densities of the liquids present in each cavity. Thus, it is possible to eliminate the prejudicial influence of pressure variations within the liquid due to pulsation. The device can in particular be used for measuring the interface level in the decanter.

  • Patent number: 4464341
    Abstract: Vortex apparatus for the continuous production of a precipitate by reacting together at least two reactants wherein it comprises a rotary bowl, having a vertical axis a fixed cylinder arranged coaxially within the bowl in order to define with the latter an annular raising chamber, thus providing a fluid flow connection with a reaction chamber defined within the fixed cylinder, reactant inlet pipes issuing into the upper part of the reaction chamber in the vicinity of the axis of the bowl, at least one weir fixed to the rotary bowl at the upper end of the raising chamber and a turbine fixed to the rotary bowl in the lower part of the reaction chamber, so as to produce a vortex in the latter and ensure the raising of part of the precipitate into the raising chamber.
