Abstract: A method of making an array of microlenses comprises forming an interference pattern having a mesh-like array of lines, recording said interference pattern in a layer of photoresist on a substrate, processing said first layer of photoresist to remove material selectively to leave a mesh-like formation of said photoresist material which corresponds to said lines of said interference pattern and which may function as a mesh-like array of astigmatic lenses, transmitting light through said array of astigmatic lenses to form a mesh-like real image made up of lines which are thinner than said lines of said interference pattern, and deriving said microlens array from said real image. The derivation of the microlens array may comprise recording the real image in a further layer of photoresist, removing the portions of the further layer activated by the real image and softening the remaining portions so that they form the microlenses. As an alternative, a mask having light transmissive   portions corresponding to the real image may be formed utilising the further layer of photoresist and microlens arrays derived from the mask.

Abstract: Pour localiser des positions le long de routes et de lignes ferroviaires, on combine traditionnellement l'observation visuelle d'un marqueur de kilométrage ou d'une rangée de marqueurs de kilométrage et l'utilisation d'un compteur de trajet, ce qui est cependant lié à un grand risque d'erreurs potentielles. Selon la présente invention, on utilise un détecteur qui réagit au franchissement de marqueurs électromagnétiques (8, 14, 20) montés dans ou sous la route, de sorte qu'une détermination automatique d'une position peut être obtenue soit par un comptage tachimétrique des marqueurs franchis, lorsque ceux-ci sont montés avec un espacement mutuel constant, soit par l'utilisation de marqueurs de positions à auto-identification, combinés avec l'utilisation d'un compteur de trajet automatique. Un tel système de marquage est bien approprié notamment pour être utilisé dans des systèmes automatiques de contrôle des trains, étant donné que les marqueurs n'interfèrent pas avec les travaux de maintenance effectués dans le ballast de la voie permanente (18).

Abstract: The invention provides an improved electrolytic process for producing anodized metal substrates such as aluminum or aluminum alloys colored using optical interference effects. In particular, the invention pertains to a novel electrolytic method of modifying the anodic barrier layer. The method results in all colors of the visible spectrum without the need for anodizing in a separate phosphoric acid-based electrolyte. 
     The modification procedures consists of treating the metal substrate with a sequence of direct and alternating currents. The alternating current is symmetrical, the voltage of the positive half-wave equal to that of the negative half-wave. A preferred sequence is direct current, alternating current, direct current. As a result, metallic oxide is deposited within the enlarged pores to a defined height, thus achieving the decomposition of light and obtaining the different colors of the visible spectrum. The modification step can be performed in the anodizing bath, the electrocoloring bath, or in specific bath with an acid electrolyte.
