摘要： Process for the filtration of paper pulp with a device that comprises a rotor and a stator; one of the two, filter (1), has perforations of slot or hole types, and the other, the backwashing element, includes means that are intended to generate pressure pulses that consist in combatting the gradual clogging of the perforations of the filter and the gradual flocculation of the pulp during the creep of the pulp between the rotor and the stator by creating deflocculation zones and/or increasing the relative speed between the pulp and the backwashing elements.

摘要： The invention relates to jacks used for the displacement of anode frames of electrolytic cells designed for the production of aluminium. According to the invention, the jack (100, 100′) comprises a sleeve (120) provided with an opening (121), an actuation rod (140) comprising an axial cavity (141) and a thread (142) and capable of moving in the said opening, a drive screw (130) inserted in the said axial cavity and capable of cooperating with the said thread so as to displace the said rod (140) in the sleeve (120) and in the said opening (121), a toothed drive wheel (150) coupled to the drive screw (130), and a worm screw that can be connected to the shaft of a drive motor (200) and that can cooperate with the drive wheel (150) so as to rotate it, and is characterised in that the centre-to-centre distance E between the axis R of the drive wheel and the axis V of the worm screw is between 100 and 350 mm, and in that the reduction ratio RR between the worm screw and the drive wheel is between 300:1 and 80:1. This jack is capable of simultaneously achieving relatively high powers and pull forces, while remaining within a relatively limited volume.

摘要： Cylindrical screen, particularly for paper pulp, of the type comprising at least one filtering element (10) positioned between two flanges (1, 2) by means of a number of bars (3). The filtering element is composed by wires (10) placed side by side and held by rings (11). This filtering element is rigid in the axial direction and is placed upstream from the above mentioned bars (3), in relation to the direction of flow of the pulp. The filtering element is held against the bars (3) through the rings (11) that are in contact with the bars without being attached to them, so as to maintain its shape by withstanding the pressure exerted by the pulp.
