摘要： The present invention relates to a process for the production of polyisocyanates containing uretdione groups bya) oligomerizing a portion of the isocyanate groups of diisocyanates having aliphatically and/or cycloaliphatically bound isocyanate groups in the presence of catalysts or catalyst systems which accelerate the dimerization of isocyanate groups and in the presence of trisubstituted phosphite stabilizers corresponding to formula (I) ##STR1## b) optionally termination of the oligomerization reaction at a degree of oligomerization of 10 to 60% by adding a catalyst poison andc) optionally removing unreacted diisocyanate by extraction or thin-layer distillation.The present invention also relates to the use of the resulting uretdione polyisocyanates as a starting component for polyurethane plastics, particularly as an isocyanate component for the production of uretdione hardeners for powder coating compositions.

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.
