Abstract: The invention relates to a surface-modified layer systems, a method for the production and use thereof. The invention in particular relates to surface-modified layer systems, comprising a substrate and a mono-layer at least partially arranged on said substrate. Said mono-layer is cross-linked in the lateral direction and covalently bonded by anchor groups to at least one surface of said substrate. Said mono-layer is also composed of low molecular weight aromatic and/or heteroaromatic compounds. The mono-layer which is cross-linked in the lateral direction is composed of low molecular weight aromatic and/or heteroaromatic compounds and is integral with the surface-modified layer system, and exhibiting the characteristics of a cross-linked solid. Said mono-layer protects the surfaces of the corresponding substrate from damage caused by friction and corrosion in a particularly advantageous manner.

Abstract: Aqueous, highly concentrated rubber dispersions, containing a reinforcing multiphase polymer dispersion comprising 60 to 95% by weight of aromatic monovinyl compounds and 40 to 5% by weight of aliphatic conjugated dienes having 4 to 9 carbon atoms, the particles of the reinforcing component consisting ofa) 20 to 75% by weight of a hard inner phase having a glass transition temperature above 70.degree. C., consisting of 90 to 100% by weight of aromatic monovinyl compounds and 10 to 0% by weight of aliphatic conjugated dienes having 4 to 9 carbon atoms,b) 78 to 15% by weight of a soft outer phase having a glass transition temperature below 20.degree. C., consisting of 30 to 70% by weight of aromatic monovinyl compounds and 70 to 30% by weight of aliphatic conjugated dienes having 4 to 9 carbon atoms, andc) 2 to 10% by weight of transition regions between these phases, whose copolymer compositions are between those of the hard and of the soft phases.

Abstract: Disclosed are mixtures of two or more polymers of which at least one is cross-linked. Interpenetrating polymer networks are on hand. The polymers mix below a certain temperature and demix above this temperature (LCST behavior). Below the demixing temperature, such interpenetrating polymer networks are optically clear, above the demixing temperature they are milky, turbid and have reduced light transmission due to the light scattering of the phaseseparated system' if the refractive indices of the components do not coincide. The demixing process is fully reversible below the demixing temperature.

Abstract: In an apparatus for acquiring stimulated action currents of the heart, a stimulation unit emits stimulation signals to the heart. Measured values that are causally influenced by the action currents resulting from the stimulation signals are acquired with a measuring system. The measured values are supplied to a processing unit under the control of a unit connected to the stimulation unit and to the processing unit which supplies the measured values to the processing unit dependent on the stimulation signals.
