Abstract: N-(2-hydroxyalkanoyl)-N,N?-dialkylureas of general formula (1) are described A-X-(A)m??(1) where A: m=0 or m=1; when m=0, X=R??, where R?? is an aliphatic, cycloaliphatic, arylaliphatic radical, C1-C18; when m=1, X=—(CH2)n—, where n is an integer from 1 and 20, preferably from 2 to 6; R is chosen among H, and alkyl radicals C1-C8, possibly substituted with halogen atoms; R? is an aliphatic, cycloaliphatic, arylaliphatic radical, C1-C18; R? is chosen among H, aliphatic, cycloaliphatic, arylaliphatic radical, C1-C18. The preparation of said compounds is described, as well as the preparation of corresponding polymers.

Abstract: In the process, doors are used in which a framework and an outer covering panel are constituted by two separated members, provided with reciprocal fixing means arranged in positions such as not to be visible from the outside of the finished motor vehicle. The painting of a body lacking the doors and the painting of the outer covering panels is executed. The fittings are installed on the framework of each door lacking the outer covering panel. Once the fittings are installed, each door framework lacking the outer covering panel is installed in the respective opening of the body. Finally, the respective outer covering panel is applied and fixed to the framework of each installed door.

Abstract: A support slide for window regulators of motor vehicles comprises a body formed, in a single piece of molded plastic material, by a plate portion and a lateral appendage. The plate portion constitutes a fixed jaw of a clamp for tightening a lower edge of a sliding window pane, and the lateral appendage has a sliding channel adapted to receive a guide rail. A movable jaw of the clamp cooperates with the fixed jaw to clamp the lower edge of the window pane. The shank of a screw for tightening the clamp is equipped with a spacer which is contained in a through-hole of the fixed jaw and which projects from the hole at least on the face of the plate portion which is turned towards the movable jaw to constitute an annular abutment surface.
