  • Patent number: 4923700
    Abstract: An artificial tear suspension system is provided which includes bioerodible mucin-type particles, lipid-type material and aqueous-type material. The bioerodible mucin-type particles are suspended in either the lipid-type material or the aqueous-type material or both. The system provides all of the components of the natural tear film layers, and thus when administered to the eye provides an effective tear film which mimics the natural tear film.

  • Patent number: 4874664
    Abstract: A birefringent plate comprising a transparent substrate and an obliquely evaporated film formed on the transparent substrate, is free from the visual angle dependence because the obliquely evaporated film is formed into a multilayer composition and the neighboring layers have a different evaporation direction. Moreover, a manufacturing method for the birefringent plate, using a device constituted of a vacuum chamber and a crucible having a large number of inclined through holes, is capable of making the film thickness of the obliquely evaporated film uniform.

  • Patent number: 4857302
    Abstract: The solubilized benzoyl peroxide is made by mixing a heated combination of crystalline benzoyl peroxide with silicone glycol copolymer wherein the temperature of the mixture is in the range from 45.degree. to 65.degree. C. The benzoyl peroxide is no longer in crystallized form and hence the benzoyl peroxide is solubilized in the silicone glycol copolymer. The cosmetic solution includes a solubilized benzoyl peroxide as described above. Further, an independent mixture of alcohol, acetone and water is made. The solubilized benzoyl peroxide is then mixed with the second mixture (alcohol, acetone and water). The resulting cosmetic solution is very stable and the benzoyl peroxide remains in solution, i.e., an analysis of the cosmetic solution does not show any crystalline benzoyl peroxide. Further, primary irritation tests indicate this solution to be minimally irritating which is important for its use as a vehicle for topical application.

  • Patent number: 4835036
    Abstract: The method relates to the production of a string (24) for a racket, particularly a tennis racket. The string is a known string, for example a gut string or a synthetic string. The conditioning of the string on a support (1), particularly a bobbin, is effected under a traction tension and the length of the string is kept constant. Thus, the elongation of the string under the traction tension effect when winding the string on the support (1) is conveniently between 5 and 15%. The stringing of the racket with the thus conditioned string (24) should be carried out in an interval of 60 minutes, but preferably 30 minutes, from the removal time of the string from its support (1). The relaxation of the string, i.e. the decrease of tension after the stringing of the racket, is considerably smaller with a string conditioned according to the invention than with a same string which has not been conditioned. Such relaxation reduction is particularly important with a polypropylene string.
