Abstract: A hub and web assembly such as for a clutch plate or pulley half in which the outer component comprises a sleeve with a web and the inner component a hub. The inturned terminal end of the sleeve bears axially against a transverse shoulder to positively determine the relative axial position of the components. Also, a bead formed from the inner component is swaged against the opposite side of the inturned terminal end. The length of the serrations on the sleeve is shorter than the total length thereof. A cylindrical bearing surface on the end of the sleeve adjacent the actual web bears tightly against a corresponding cylindrical bearing surface on the hub remote from the transverse shoulder. This arrangement permits limited torsion of the web without loosening the mating serrations on the components.

Abstract: The invention relates to an apparatus for sampling a liquid conveyed by a plurality of tubes.The sampling apparatus comprises a cylindrical enclosure with a vertical axis and a circular cross-section having a given length. The enclosure has a lower planar wall, a side wall and a cover which seals the upper part of the enclosure. One of the walls is perforated by a plurality of orifices whose number is at least equal to the number of tubes. The end of each tube issues into one of the orifices which are regularly disposed along a portion of a single curve without a double point. The length of this curve portion exceeds that of the given length. The sampling device also comprises a movable sampling member in the form of a single suction tube having a free end associated with means for simultaneously rotating the suction tube about the axis of the enclosure and for translating the tube in such a way that its free end remains in contact with the wall provided with orifices and moves along the curve.
