Abstract: [Seed distribution device for an agricultural machine with a housing, a seed inlet, a perforated disc driven to transport the seeds and an outlet tube, the seeds being transported from a tank to the outlet tube by means of an air pressure difference, the air pressure difference being interrupted so that the seeds leave the disc to reach the outlet tube, the outlet tube comprising a first portion into which the seeds enter via an inlet, this first portion of the outlet tube being located inside the housing and being oriented so that the inlet is adjacent to the disc; the distribution device comprises a fairing element in which a first opening extending along a first fairing plane is carried out, and the fairing element covers the first portion of the outlet tube.

Abstract: A method of detecting and/or monitoring the forming and/or the growth of defects, in particular cracks or plastic deformation, and/or suspected defects in ferromagnetic structures, such as civil engineering and marine structures, comprises reading, at a first point in time, values of magnetic flux leakage (MFL) from a plurality of magnetometers placed over or near a defect or a suspected defect and storing the values of magnetic flux leakage (MFL). The method further comprises reading values of magnetic flux leakage (MFL) from a plurality of magnetometers at a further point in time, processing the values of the further reading with the values from the earlier reading, and determining the location of a singular point of the defect from the processed further reading.

Abstract: A metallic sealing assembly between a rotating shaft and a fixed frame comprises: a flexible metallic seal having two tori, inner and outer, that are concentric and of different average diameters, comprising a metal envelope which encases and holds the inner and outer tori; a shaft rotating about an axis of rotation, comprising an annular shoulder against which the seal comes to press; a counter-face, comprising a contact face against which the seal comes to press; a wedge block positioned around the rotating shaft such that the seal is held between the wedge block and the contact face, the wedge block mounted to slide on the rotating shaft; a metal part which forms a cap through which the rotating shaft passes and which is secured to the frame and/or to the counter-face, the rotating shaft being free to rotate with respect to the cap and axially secured to the cap.

Abstract: A declutching device for a seed drill distribution element including a locking element and a support element on which the locking element is mounted, in which the locking element allows two stable positions relative to the support element and can be moved between these, the locking element being configured, when in a stable position, to be able to declutch the distribution element.

Abstract: An agricultural machine having a trailed chassis and a transverse bar in several portions extending substantially transversely to the direction of advance in the work position and extending substantially parallel to the direction of advance in the transport position, the transverse bar includes two portions able to be folded around a first respective articulation with a substantially vertical axis, each portion supports a seeder device made up of a hopper and a seeder bar. Each seeder bar is fixed on the corresponding portion using a second articulation with a substantially horizontal axis oriented parallel to the direction of advance in the work position.

Abstract: The seal comprises a casing made of two portions (1, 2) crimped into one another with an accurate hermetic position adjustment at interfaces (15, 6b) and a composite structure comprising inside the casing an advantageously flexible and resilient core (24) and a winding (20) of brush bristles. This structure directly extends facing internal faces (9, 10) facing each other in the casing, which compresses the same and has an arcuate shape having a slightly higher radius of curvature. The composite structure is held at an accurate position, firmly but free of constraint.
