Sorting table with sorter rolls eliminates foreign matter remaining mixed in with the products of the harvest of small fruit. The sorting table features a sorting system constituted by a succession of rotating rolls of cylindrical shape arranged in parallel so as to form a mobile sorting plane, and a locomotion device, allowing the rotating drive of the rolls in the same direction, so as to allow transporting the grapes dumped on the upstream part of this sorting plane, in a direction that is perpendicular to the axis of the rotating cylindrical rolls and over the entire length of the sorting plane. The rotating cylindrical rolls allow the passage and drop-off of only the small fruit to be sorted, whereas the foreign matter of a size larger than that of the latter remains on the surface of the mobile sorting plane and is evacuated at the downstream end.

Stalk separator for the de-stalking of small fruit picked in bunches, in particular for the de-stalking of grapes. The invention includes a conveyor belt and a de-stalking device positioned above this conveyor belt. The de-stalking device includes at least two spaced assemblies positioned opposite each other, each assembly featuring a number of stacked separator arms. The mechanical drives communicate a high frequency oscillating movement to the assemblies of stacked separator arms.

Hydraulic steering for automobiles and self-propelled machines features at least two steering wheels and has a steering wheel linked to a hydraulic distributor, characterized in that it has at least two hydraulic modules. Each module includes a module body including an assembly having a double piston integral in translation with a rack. The piston is housed with a sliding aptitude in a cylinder body in which it delimits two opposite chambers. Each module also includes a gear meshing with the rack. Each of these modules is linked, on the one hand, through the intermediary of its pivoting element to one of the steering wheels and, on the other hand, through the intermediary of its fixed organ, to the vehicle chassis, and in that said distributor is connected to one of the chambers delimited by the rack piston of each module, the second of the chambers communicating with each other.

A sorting table with grading rolls supported by end supports and positioned to form a sorting plane. The rolls are rotated in the same direction and configured to create at least one opening between adjacent rolls to permit the pass-through of only the products to be sorted or calibrated. Larger products remain at the surface and are evacuated downstream. The gap between rolls can be modified. Elastic elements are interposed between said end supports and means of actuation for are provided bringing said end supports and the rolls supported by the latter closer together or moving them farther apart, in opposition to the antagonistic action exerted by said elastic elements, to decrease or increase the cross section of the openings, displacements in the opposite direction of said end supports and of the grading rolls being achieved by the action of extension or compression of said elastic elements.
