Abstract: The invention relates to a sampling valve, for taking samples of fluid from a common collecting vessel in order to perform a plurality of analyses using reagents. The valve of the invention comprises two members that are movable relative to each other, comprising a sampling member having sampling loops, each intended to receiving an aliquot of fluid, and a connection member capable of assuming at least three functional positions relative to the sampling member. These three positions enable the delayed access to two separate sampling circuits in order to fill them and to dispense reagents to the loops that make them up.

Abstract: This invention relates to a bending press for bending metal foils, comprising a mobile panel and a fixed panel. The fixed panel comprises two slots open on the lateral faces of the lower panel and symmetrical with respect to the transverse median plane of this fixed panel. The bottom of each slot is formed by the inner wall of a through bore made in the lower panel which extends over an angle close to 360°, in order to distribute the stresses due to the bending over a broader area. A safety stop is provided in the opening of each slot in order to limit the vertical displacement of the ends of the upper part of the lower panel.
