  • Method for manufacturing a FBG having improved performances and an annealing-trimming apparatus for making the same
    Patent number: 6956994
    Abstract: A method for manufacturing a FBG having improved performances and an annealing-trimming apparatus for making the same are provided. The trimming and the annealing steps are advantageously combined into a single process in order to efficiently fabricate complex FBG filters with improved performance. The method comprises the steps of UV-writing a FBG in an optical fiber prior to annealing-trimming characteristics of the FBG by performing the sub-steps of monitoring characteristic data of the FBG while generating a controlled complex temperature profile along the FBG with a heating means according to the characteristic data for providing an accurate controlled annealing process of the FBG, thereby providing an accurate trimming thereof.

  • Emulsion of the oil-in-water type based on silicone oil and its use in cosmetics and dermatology
    Patent number: 5449510
    Abstract: A stable cosmetic emulsion of the oil-in-water type contains an aqueous phase, an oily phase, and an emulsifier, with the oily phase containing at least one silicone oil and the emulsifier being a polyoxyethylenated polyorganosiloxane with the following formula: ##STR1## The stable emulsion is especially desirable in the fields of cosmetics and dermatology, particularly in creams, lotions, and makeup products.

  • Cosmetic composition in the form of a solid gel
    Patent number: 5286755
    Abstract: A solid, transparent or translucent non-alcoholic cosmetic gel contains 65 to 99 weight percent of a polyol, 0.1 to 5 weight percent of a dibenzylidene-ose, 0.1 to 5 weight percent of a hardening agent of the sulfosuccinate type and 0.5 to 40 weight percent of water. The gel is employed in makeup products.
