Abstract: An electric machine includes a stator, a rotor, a housing and a shaft. The stator is connected to the housing via an electrically insulating torque support. An electrically insulating flange is disposed on the shaft. The shaft is connected to a flange of a bearing shaft via said flange, the bearing shaft housed in a bearing which is arranged in the housing.

Abstract: A process for the bioactive coating of the surface of substrates, which entails graft polymerizing at least one vinyl monomer of the formula (I): R—(A)a  (I) in which R is an olefinically unsaturated organic radical, having the valence a, A is a carboxyl group —COOH, sulfuric acid group —OSO2OH, sulfonic acid group —SO3H, phosphonic acid group —OPO(OH)2, phosphoric acid group —PO(OH)2, phosphorous acid group —OP(OH)2, phenolic hydroxyl group or a salt of one of these groups, and a is an integer of from 1 up to and including 6, under radiative induction or thermally on a substrate surface which his been treated beforehand with a macroinitiator having groups which form free radicals in side chains of the polymer framework; with the proviso that a vinyl monomer I in which A is the carboxyl group —COOH or a salt of the carboxyl group contains at least one further radical A having a different one of the definitions specified for A or is used together w

Abstract: The invention relates to a process for making the surface of polymeric substrates hydrophilic, which includes coating the surface of a polymeric substrate with a solution of a macroinitiator, wherein the macroinitiator includes a polymer framework and side chains attached to the polymer framework, and wherein at least one of the side chains includes at least one free-radical-forming group. Optionally, a hydrophilic vinyl monomer or monomers may then be free-radical polymerized or graft polymerized onto the macroinitiator-coated substrate. A crosslinking vinyl monomer may optionally be used together with the macroinitiator or the hydrophilic vinyl monomer. The invention also relates to polymeric substrates having hydrophilic surfaces obtained by the process, and articles that include the hydrophilic polymeric substrates.
