  • Patent number: 5884560
    Abstract: The invention relates to a printing form for a rotary relief-printing method, in which the printing dots transferring the printing ink constitute a half-tone screen and are superimposed by a relief structure constituted by indentations. Such printing forms are used, for example in flexographic printing methods for printing glass plates, for example display screens having a luminescent material coating. In the manufacture of these screens, the printing ink must be applied homogeneously and the ink dots appearing in the printed image must have a uniform border area. According to the invention, the printing form is to this end implemented in such a way that the relief structures are arranged homogeneously relative to the printing dots and, if the printing dots are periodically spread across the printing form, these relief structures are superimposed on the printing dots preferably with the same period.

  • Patent number: 4822616
    Abstract: A vaginal ring comprises a supporting ring 1 free of active agent. A layer 2, which contains an active agent such as a steroid, is applied on its outer rim, optionally in a continuous groove provided in the supporting ring. This layer, in turn, is coated with a layer 3 devoid of active ingredient. All components preferably comprise an LTV silicone elastomer. The ratio of the thickness of the layer 2, containing an active agent, to the layer 3, free of active agent, is about 5-50:1. As a result, a long-term and uniform release rate is achieved for the active agent.
