Abstract: A movable support (5) provided at its botton surface with a pad (19) made of antifriction material and slidable on a lapped reference surface (2).The movable support includes discharging jacks (8) which bear indirectly against the frame. The effort corresponding to the sum of the independent efforts of each jack must be lower than the effort exerted by the weight of the movable support and of its optional accessories, so as to minimize the difference between the sliding effort at the beginning and the friction effort of displacement in any direction on one plane and so as to limit, in the displacement referential X,Y,Z, the deviations of the geometrical positions of a sensor or of a tool. A motor (26) and a particular reducer drive the movable support in a translation direction X. There is provided a second drive unit for a translation in the direction Y.By using as an accessory a micrometric displacement table and a follower, it is possible to take tridimensional profilometric measurements.

Abstract: Membranes such as fluorine-containing cation exchange membranes are wrapped on a roll for shipment, without using adhesive to fasten the membrane to the core or to itself at the end of the wrap. Instead, paper is taped to the core and interleaved with the membrane. At the end of the wrap, paper is again interleaved with the membrane and the paper is taped to itself.

Abstract: A connector assembly, in particular for use in an electrically adjustable shock absorber of the type comprising a cylindrical housing in which shock-absorbing means and electrical control means are accommodated. The connector assembly comprises a connector having an elongated supporting element of electrically insulating material to be accommodated in the cylindrical housing. At a first end of the supporting element contact elements and positioning means, comprising an approximately T-shaped polarization lobe projecting outwards in the lengthwise direction of the supporting element, for contacting a further connector are situated. From the first end past the second end of the supporting element eletrical conductors, preferably contact tracks on a flexible film connected to the contact elements, extend for connection of the electrical control means.
