Granted: 2009-04-21
Abstract: A porous polymer membrane is made by dissolving a polymer consisting primarily of vinylidene fluoride in a suit-able liquid, casting the polymer solution to form a thin layer on a substrate, and then slowly evaporating the liquid phase (without contacting the layer with any other liquids) so that a substantially uniform microporous membrane of polymer is formed. The liquid may comprise a solvent for the polymer, combined with a small proportion of a non-solvent which dissolves in the solvent. Alter-natively the liquid may be a latent solvent. The evaporation process may be performed at a temperature above ambient temperature, and involves exposing the film to dry gas. The microporous membrane or film may be used to form a solid electrolyte for a lithium cell, by soaking it in a non-aqueous liquid electrolyte, the film combining with the electrolyte solution to form a solid electrolyte or a gelled electrolyte.

Abstract: Selon l'invention, une partie d'un premier paraboloïde collecte et focalise la lumière diffuse émise par une lampe en faisceaux parallèles dirigés sur une partie d'un second paraboloïde, qui refocalise la lumière sur un homogénéisateur. Le second paraboloïde a une forme sensiblement similaire à celle du premier réflecteur paraboloïde. La source et la cible sont situées au niveau des foyers respectifs des paraboloïdes de manière que le flux optique émis par la source soit imagé sur la cible, avec une distorsion minimale, dans un système d'imagerie ne grossissant quasiment pas. On peut configurer le système pour qu'il régule la longueur d'onde et l'intensité en insérant un filtre supplémentaire. En outre, on peut ajouter un rétroréflecteur pour augmenter la densité générale du flux au niveau de l'homogénéisateur. La sortie convient tout particulièrement à la fourniture de lumière au système d'éclairage des projecteurs.
