  • Patent number: 7976614
    Abstract: The invention relates to a method for cleaning the filters of a vacuum cleaner. A dirt collecting container of the vacuum cleaner has a suction inlet and is in flow connection with at least one suction unit via at least one filter and at least one suction extraction line. At least one external air inlet is provided which opens into the suction extraction line downstream of the filter and can be closed by a closing valve. The closing valve has a movable valve body which is acted upon by a closing spring with a closing force. In order to clean the filter, the closing valve is opened and the side of the filter that is oriented away from the dirt collecting container is impinged upon by external air. The valve body is acted upon, irrespective of its position, by the closing force of the closing spring and, in a position at a distance from the valve seat, additionally acted upon by a repulsion force of a resilient stop element.

  • Patent number: 7949447
    Abstract: A steering system and method are capable of steering a plurality of vehicles arranged in a train with adjacent vehicles pivotally connected to each other for movement about a vertical axis. Each vehicle has a pair of steerable wheels with one pair at one end of the train being a selected leading pair having its steering angle determined by an operator. An electrical control system automatically steers all of the wheels trailing behind the leading pair. Vehicle angle sensors measure intercar angles between adjacent vehicles and provide this information to the control system. An indicator provides the controller with the current distance traveled by the train. Wheel angle sensors provide signals indicative of the current steering angle for each wheel pair. The controller adjusts the actual steering angle for each trailing pair to a desired angle by calculating adjustments based on the measurement inputs.
