    摘要： A molding composition comprising thermoplastic polyurethane is disclosed. The polyurethane is characterized in having ultimate tensile strength (UTS) and elongation at break (EAB) values after hot storage which are, each, at least 60% of the corresponding value before hot storage, glass transition temperature equal to or lower than −50° C., UTS and EAB values after hydrolytic storage which are, each, at least 80% of the corresponding value before hydrolytic storage, and Shore A hardness of 70 to 95. The polyurethane is a product of a reaction comprising an aliphatic diisocyanate, a mixture of polyols and a chain extender and contains a UV stabilizer, an antioxidant and an optional anti-hydrolysis agent.

    摘要： A circuit for damping hunting oscillations of controlled electric machines. The circuit is provided with a measuring circuit for determining the hunting oscillations and an identifier circuit for determining the angle components of such hunting oscillations. A phase shifter circuit is provided for receiving the angle components produced by the identifier circuit and forming a hunting oscillation correction signal which is shifted in phase from the hunting oscillations by a predetermined phase angle. The hunting oscillation correction signal is conducted to a control unit of the electric machine. The invention is particularly useful in damping hunting by the rotors of voltage controlled synchronous generators.
