Abstract: A stamp for patterning onto a receiving surface (103) of an object (101) according to a defined pattern (P) comprises a stamping surface (21) of a resilient diaphragm (20). The stamping surface (21) is planar at rest. The pattern (P) is reproduced on the stamping surface (21) and the diaphragm (20) is affixed to a rigid body (13) along a peripheral edge, so that a middle part of the diaphragm (20) can move along a direction perpendicular to the stamping surface (21). The diaphragm (20) is more flexible near the peripheral edge than in the middle part. Then, the pattern (P) printed on a pseudo-spherical receiving surface (103) using the stamp exhibits few distortion.

Abstract: A process for making a mould piece having a main curved surface bearing an utilitary microstructure which comprises transferring a utilitary microstructure from a master piece main surface to a main surface of a flat cured elastomeric film; pressing the cured elastomeric film and a master article against each other so as to conform the overall shape of said cured elastomeric film to the curved shape of the main surface of the master article and to spread over a curable coating composition between the curved main surface of the master article and the main surface bearing the replica of the said utilitary microstructure of the cured elastomeric film; curing the coating composition; removing the cured elastomeric film and depositing a layer of a metal or a metallic alloy on the exposed main surface of the hard coating of the master article; and recovering said metal or metallic alloy layer to obtain a mould piece having a curved main surface bearing a replica of said transferred utilitary microstructure.

Abstract: The application of a mark on the surface of an ophthalmic glass of the type with an external hydrophobic and/or oleophobic coating with a low surface energy on a substrate or a coating with a high surface energy comprises: (a) positioning a mask, with a configuration complementary to the desired mark, between the surface to be marked and an energizing discharge source able to eliminate the external coating to reveal the underlying substrate or high energy coating; and (b) depositing on the outer coating, a temporary protective coating having a surface energy higher than that of the external coating and a thickness of less than 5 nm in order to allow the discharge to act on the external coating across the temporary protective coating.

Abstract: De manière connue en soi, il s'agit de provoquer le dépôt, sur le substrat courbé (l0) à traiter, d'une couche de matériau en provenance d'une source de matériau (13) donnée. Suivant l'invention, on interpose, ent re le substrat courbé (10) et la source de matériau (13), un cache (19) fixe par rapport au substrat courbé (10), en choisissant, préférentiellement, pour cache (19), un cache comportant une partie annulaire (20). Application, notamment, au traitement antireflet des verres de lunettes.

Abstract: The invention concerns a support of the type comprising at least a first base (13), and, borne by the latter, for maintaining such an optical lens (10) at its edge (11), at least three support pins (14A, 14B). The invention is characterized in that the base comprises, for its own support, a plane support surface (16) whereof the peripheral outline (P1) is globally circular, its radial dimension (D1) along a particular radius (R) of said support surface (16) is at least equal to its axial dimension (D2) perpendicularly to the plane thereof. The invention is particularly useful for maintaining an optical lens in a processing apparatus using spin coating technique.
