Abstract: A multicomponent, in situ foaming system is described for the preparation of interpenetrating polymeric networks of foamed polyurethane and at least one further polymer for in situ construction purposes with a polyisocyanate component (A) and a polyol component (B) for forming the polyurethane, and further components (C) and (D) for forming the further polymer. Components (A) and (B) are present in a reaction-inhibiting, separate form. The components (A), (B), (C) and (D) are present in the form of one or two mixtures, in which the components (A), (B), (C) and/or (D) are contained separately in a micro-encapsulated form in order to inhibit reaction so that the components polymerized with formation of the interpenetrating polymeric network only when the components are brought into contact with one another after destruction or opening of the microcapsules.

Abstract: The invention concerns a binding matrix containing a carrier material and a solid phase reactant which is adsorbed to this via anchor groups that is capable of binding to at least one free reaction partner wherein the solid phase reactant forms a dilute and essentially laterally homogeneous binding layer on the surface of the carrier material. In addition a method for the determination of an analyte in a sample solution is claimed in which a solid phase reactant is used which is a component of a binding matrix according to the present invention. In this process the specific binding reaction is preferably determined by optical reflection techniques.

Abstract: A circuit arrangement (1000, 2000), preferably for a coupling network component of a network node in a packet-switching data network, is disclosed which has a wide parallelization of the data packet signal by means of shift registers (60), so that it is possible to operate internally with a greatly reduced operating speed. In particular, an arrangement of the components on a single semiconductor wafer (3000, 4000) permits an especially wide bus (20), which can be constructed extremely advantageously with a surface-optimized floor plan (3000, 4000).
