摘要:
A process to invert a structure, for example a vehicle body after an equipment mounting phase, namely of mobility means, on the underside of said structure, process wherein the structure is made to swivel around an instantaneous axis of rotation which is perpendicular to the longitudinal axis of the structure, such axis of rotation being located in the vicinity of a first end of the structure, maneuvering means being positioned at the other end of the structure to control this swiveling.
摘要:
An assembly process for a vehicle of substantial height, process in which at least one pit is implemented that is able to accommodate the vehicle, the latter being positioned on at least one removable floor platform able to raise the vehicle with respect to the bottom of the pit, the floor platform being positioned at the required height by means of positioning means.

摘要:
A method and apparatus for handling a wheel of large mass from a storage position to enable its mounting onto the hub of a vehicle, wherein the method includes placing a tire in a handling device having two ends which are of substantially equal length, the length being longer than the perimeter of the wheel, between two ends of the handling device, bringing together the ends of the handling device so as to imprison the wheel within the handling device, and hooking the ends of the handling device into a handling and lifting device.
摘要:
A process for obtaining aminopolyamide-epichlorohydrin resins with a 1,3-dichloro-2-propanol content which is undetectable by ordinary means of vapor-phase chromatography. The process consists of passing the products resulting from the successive condensation of aminopolyamides and epichlorohydrin through two columns of activated carbon. In this way, aqueous resins are obtained which are free of toxic products, and which are particularly valuable as wet strength additives in the manufacture of papers for medical, cosmetic or food contact uses.
