    摘要： An aqueous binder dispersion that includes at least one copolymer (P) containing carboxylic acid and/or carboxylate groups. The copolymer (P) includes structural units of carboxyl-free (meth)acrylic esters with a cycloaliphatic structure, and at least 25 mol % of the carboxylic acid groups of the copolymer (P) in the dispersion being present in triethanolamine-neutralized form. The aqueous binder can be used in aqueous coating materials, which can be used to coat a substrate.

    摘要： The present invention relates to polyaddition compounds, which are solid below 40° C. and liquid above 125° C., are prepared by the reaction of an isocyanate component containing uretdione groups with a polyol containing ester and/or carbonate groups, other than hydroxypivalic acid neopentylglycol ester, and have a) an average isocyanate functionality of 2.0 to 8.0 and a content of free isocyanate groups (calculated as NCO; molecular weight=42) of 2.1 to 6.0 wt. %, b) a content of uretdione groups (calculated as C2N2O2; molecular weight=84) of 10 to 19 wt. %, c) a content of urethane groups (calculated as —NH—CO—O; molecular weight=59) of 10 to 17 wt. % and d) a content of ester groups —CO—O (calculated as —CO—O; molecular weight=44) and/or carbonate groups —O—CO—O (calculated as —CO—O; molecular weight=44) of 1 to 17 wt. %. The present invention also relates to a process for the preparation of these polyaddition compounds to two-component polyurethane powder coating compositions containing these polyaddition compounds as the crosslinking agent and isocyanate-reactive compounds as the binder.

    摘要： A rubber bearing, in which a liquid-filled working chamber is bounded by an expanding member and by a compensating wall that is capable of moving back and forth in the direction of the working chamber, wherein the compensating wall consists at least partially of a material that is capable of being moved by magnetic forces and extends relatively movably with one partial area into an air gap between a pair of coils comprised of two mutually opposing magnetic coils, which are rigidly supported in two coil braces and are capable of receiving an electric alternating current. The magnetic fluxes of the magnetic coils in the air gap are superimposed upon the magnetic flux of at least one permanent magnet, and the magnetic coils synchronously receive an electric current in such a way that the magnetic flux generated by the permanent magnet is strengthened on one side of the compensating wall and weakened on the other side of the compensating wall.

    摘要： A hydraulic damped rubber bearing includes a damping devices for damping low and high-frequency vibrations. A damping device for low-frequency vibrations utilizes throttle or resonant effects and a damping device for high-frequency vibrations above 10 Hz utilizes a flexibly expandable waveguide, which is closed off at the end distal the working chamber by an element having a reflection-free resistance to flow.
