  • Equipment and method for vibration damping of a lift cage
    Patent number: 7314118
    Abstract: An improved equipment and method for reducing vibrations of a lift cage is intended for use in lifts of the type having a lift cage is intended for use in lifts of the type having a lift cage guided along rails in which a sensor for detecting positional changes of the lift cage and/or lift cage accelerations is coupled to a regulator which in turn controls an actuator for changing the position of the lift cage relative to the rails. An output signal developed by the regulator is limited to a maximum value for the setting signal to be sent to the actuator. A difference between the regulator output and the limited output is computed and fed to the regulator as an additional input. The regulator is constructed in such a manner that the difference fed back to the regulator remains as small as possible. This improves response of the vibration inducing equipment.

  • Self-locking bolted fastener
    Patent number: 7300237
    Abstract: A bolted fastener for joining components, such as a bracket fastened to a crosspiece, includes a bolt, a nut and an eccentric. A square neck of a bolt fits into an oblong hole in a component and prevents the bolt from turning. The diameter of the eccentric that serves as a wedging means fits into the slightly larger diameter of the receptacle hole, allowing the eccentric to fit into the receptacle hole. When the nut is screwed on the bolt, the eccentric rotates about the bolt and, on account of its eccentricity, wedges itself within the receptacle hole. The wedged eccentric prevents accidental loosening or accidental unscrewing of the nut.
