  • Patent number: 8631911
    Abstract: A drum brake for motor vehicles is described, comprising a hydraulically actuable service brake and a parking brake that is actuable mechanically by means of a Bowden cable, wherein a lasting initial tension of the Bowden cable is to be ensured. For the initial assembly, a retaining plate interlocks the hand brake lever with the web plate of the secondary shoe against the force of the resetting spring. After assembly of the Bowden cable and adjustment of the initial tension of the hand brake cable the interlock is cancelled by pulling powerfully on the hand brake stem. If over the years the hand brake cable stretches, a design-determined initial tension is constantly maintained by the continuous force of the resetting spring.

  • Patent number: 7395980
    Abstract: The invention relates to a device for separating and transporting away raw materials once they have been ground, from cutting tools embodied as separating/cutting units and pertaining to machines for meat mincing, especially mincers. The inventive device is embodied as an adaptable tool and can be associated with separating and cutting units (1) of mincers. Said device is characterized by a transporting tube (4) and a discharge screw (3) arranged inside said tube and driven by external means. Furthermore, the adaptable tool and the discharge screw can be positioned and arranged in different positions for each separating and cutting unit (1).
