Abstract: The invention relates to a blind assembly process for at least one component and an assembly device. The blind assembly process for at least one component designed to be placed in a housing that is difficult to access comprises a step for the three-dimensional connection of the component using a link with a multifunction plate a step for formation of the means of positioning the multifunction plate in a first wall in which at least one hole is formed through which the link and the component can pass, the said link positioning the component in space so that once the plate has been positioned, the component is in position in the housing a step in which additional components are fixed onto the component.

Abstract: A process for improving sliding qualities of a slide contact or carriage on at least one rail, and a device for implementing this process. The carriage includes a part intended to be moved along the rail. A section (4) shaped to conform to the rail is placed on the surface of the rail, closely following the contour thereof and smoothing out irregularities or deformations of the rail.

Abstract: This invention relates to a process for production of shaft passages in a molded plastic part, a mold, and the use of the process of production in, for example, a flap device particularly for a feed system for internal combustion engines, characterized in that it consists of: providing a recess by the advance of a slide of the molding tool between two adjacent bearings each associated with sites of different moving parts, and forming a bearing portion on each side of the sites of each moving part by a moving wedge relative to a slide, whereby the wedge carries a pin that is intended to form a bearing portion of one side of the moving part.

Abstract: A vehicle door equipment plate incorporating the window winder function and at least one other function is characterized in that it is built into a conventional door structure consisting of a press-formed shell having an outer metal panel connected to an inner metal panel provided with at least two openings separated by a strengthening metal sheet connecting piece placed substantially transversely with respect to a longitudinal direction of the door. One of the openings provides a passage for a window guide element integrated at one end of the equipment plate, the latter being made from moulded plastic.

Abstract: Device for controlling the opening of a blanking off flap of a pipe, wherein the blanking off flap of the pipe is controlled in a first direction by a device using a spring made of a shape memory alloy as soon as the temperature rises and a return spring which activates the flap in a direction opposite the first direction as soon as the temperature drops.
