In the illustrated embodiments, an elastomer body has a relatively thin metal layer overlying the elastomer surface to be loaded so as to prevent adhesion at the elastomer surface in spite of a long period of dwell in contact with a relatively more rigid cooperating part such as a hard rubber stop. In a basic form, a thin metal sleeve may encircle a cylindrical elastomer body. The outer surface of the sleeve may be grooved for extra adhesion resistance. In a further development, the sleeve is formed as a helical wire spring which may be confined between two flanges integral with the elastomer body.

Arrangement for a low-noise and low-shock interception of moving masses

A printer carriage as for a teleprinter or a typewriter is carried on a toothed belt along a printing row, the belt being driven in forward and reverse directions by a reversible stepping motor operating without feedback. Deceleration and precise stoppage of the carriage during carriage return movements are governed by fixed signal generators along the printing row and a ring counter in the motor control unit. Stoppage occurs upon coincidence of a signal from the ring counter and a signal from a generator at the row commence position, combined in a logical AND- circuit.
