Abstract: The present invention relates to a compression test device for a paper strip, including means for laterally holding the strip to limit its buckling during the testing. The lateral holding means include a tube in which the strip is freely rolled with more than one turn.

Abstract: An apparatus for measuring the respective elongations of several sample strips (13), comprises: a vertical frame (51) provided with a fixed upper gripping jaw (27) and a mobile lower gripping jaw (15) to maintain each of the strips (13), the lower gripping jaw (15) stretches the strip by gravity effect; and an electronic displacement sensor (33, 35) associated to each lower gripping jaw (15). Each gripping jaw comprises a sole and a plate articulated on the sole. A magnet (11) is mounted in the sole, flush with a contact surface of the sole, for urging the plate against the contact surface by magnetic attraction.

Abstract: Method and apparatus for regulating the conditioning of a gaseous flow that includes hearing the gas to a desired level and saturating it with a liquid at a reduced pressure and mixing the saturated gas with a second non-saturated gas in proportion to attain a desired conditioning.

Abstract: A coupling device comprises a non-magnetic female part (1) comprising an aperture ending in a coupling surface of the part and a magnet (7) accommodated in a recess in an offset position with respect to the coupling aperture; and a male part (3) comprising a portion with a circular section (11) made of a ferromagnetic material, the diameter of which is higher than the smallest size of the aperture, and intended to be drawn by the magnet against the coupling surface while being centered in the aperture. This device can be used in an apparatus for suspending any of several objects to a support.
