Abstract: A method for manufacturing a correctable lens for glasses from an injectable thermo-plastic polymer material, or other moldable polymer, includes the step of molding a polymer blank provided with the contour of the corrective lens. The polymer blank is joined with a peripheral piece having the same internal radius of curvature as that of the polymer blank creating a lens blank. The internal face of the lens blank is ground and polished to obtain the desired ocular correction. The polymer blank is then separated from the lens blank, the lens blank now being the corrective lens ready for assembly with the frame.

Abstract: This invention relates to a suspension for vehicles, wherein the wheels are associated with the bodywork by means of a flexible assembly essentially constituted by two longitudinal blades and by two transverse blades connected to the bodywork by means of elastically deformable connecting elements, wherein:--the ends of the longitudinal blades and transverse blades are located in two planes spaced apart from each other, these two planes being parallel or not;--at the front of the chassis, the ends of the longitudinal blades are mounted so as to allow a momentary longitudinal displacement under the effect of a shock and to avoid any transverse or angular displacement;--at the rear of the chassis, the ends of the longitudinal blades are blocked in torsion in the hub-holder elements.
