Abstract: A method is described for producing a microstructured surface relief by applying to a substrate a coating composition which is thixotropic or which acquires thixotropic properties by pretreatment on the substrate, embossing the surface relief into the applied thixotropic coating composition with an embossing device, and curing the coating composition following removal of the embossing device. The substrates obtainable by this method, provided with a microstructured surface relief, are particularly suitable for optical, electronic, micromechanical and/or dirt repellency applications.

Abstract: The invention relates to a method and a device for signalling a codec negotiation over heterogeneous signalling networks. In a heterogeneous network environment, interfaces can be present, for a transmission, which are governed by limitations in terms of a codec negotiation. Especially cases in which only a limited set of codecs is supported and/or signalled in the target network, or in which the target network only has a limited number of elements, for example one element, from which proposed codec lists can be extracted or evaluated, present problems. If this is the case, as a result, connections are rejected if non-supported codecs are signalled. The aim of the invention is to provide an improved method for signalling codec negotiations, whereby as few as possible signalling calls are rejected. To this end, a significant idea of the invention is that the list of supported codecs is resorted before the signalling call in the emission network.

Abstract: Components are separated from liquid or gaseous media with the aid of a nanocomposite comprising nanoparticles in a matrix, wherein the liquid or gaseous medium is brought into contact with the nanocomposite in such a way that at least part of the components to be separated off is bound to the nanocomposite and the resulting laden nanocomposite is separated from the liquid or gaseous medium.

Abstract: A window assembly which includes at least some components which may be assembled in a snap-fit manner. In certain example embodiments, a combination of rotation/pivoting insertion, and a snap-fit assembly engagement of one or more components may be utilized in assembly. For example, a component may be engaged with a portion of another component, and then rotated and/or pivoted about a pivot axis until a portion of the component becomes engaged with a part of the window in a snap-fit manner. The combined use of rotation/pivoting about a pivot axis and snap-fit engagement allows for self-alignment to be realized during assembly thereby simplifying the assembly process.

Abstract: A muntin bar assembly for a window or door comprising a peripheral frame; a surface contained within the frame; at least one continuous muntin bar and at least two discontinuous muntin bars on at least one side of said surface. The continuous muntin bar and discontinuous muntin bars both contain a continuous recessed portion on their underside and are connected together using an intersection clip having a spring-type arrangement which forms an intersection of the bars. The intersection clip has a raised central section that fits within the recessed portion of the continuous muntin bar; and further has two extensions positioned at opposite sides from the central portion which permit engagement of the discontinuous muntin bars to form the muntin assembly. In another embodiment a second muntin assembly is provided on the opposite side of the surface such that one assembly is an outer assembly and the opposite assembly is an inner assembly.

An intermediate station (e.g., gateway) is provided with a services distributor that serves as a unit for differentiating services control data to be carried out locally and services control data to be passed farther along the signaling segment. The services distributor makes use of a code by which each service is assigned to a specific station.

Abstract: A microbicidally coated article, especially a container, having on at least part of it a coating comprising an organically modified inorganic matrix comprising silver colloids which is obtainable by application of a coating composition comprising a) a hydrolysate or condensate based on at least one hydrolysable silane with at least one non-hydrolysable substituent and b) a silver compound to the surface of the article and treatment with heat and/or radiation to form the silver colloid coating.
