Abstract: A device for conversion of a rotational movement into a movement of each of two working levers defining a truncated cone and a self-rotating movement of each of the two working levers and vice versa comprises a lever bearing element which is rotatable around a rotation axis. The two working levers are each self-rotatably positioned around a self-rotation axis in the lever bearing element. A planetary wheel is arranged in a non-rotatable manner on each working lever. The planetary wheels are each coupled to a sun wheel, which is able to be blocked from turning, via a transmission wheel, the sun wheel being arranged around the rotation axis. This device for conversion of movement is utilisable for a great variety of uses and has a simple mechanical construction.

Abstract: A device for converting a rotational movement for directing displacement of a flowable medium is provided with a mount and two rotatably mounted fixed axles which are arranged at a distance from one another on the mount and on which are articulated two end portions of a half cube-linkage chain having two lateral members and a middle member, the two lateral members being connected to the fixed axles and to the middle member by means of pivot axles which are successively offset relative to one another by in each case 90.degree.. The device is characterized in that the middle member and at least one of the two lateral members of the half cube-linkage chain cooperate to form sheet-like driving elements for displacing flowable substances.

Abstract: A device for converting the energy of a flowable medium into torque, or vice versa, employs a pair of linkages positioned on opposite sides of a common mount such that the linkages form mirror images of each other. Each linkage comprises a plurality of link members which are pivotally attached to each other. A first rotatable axle is attached to one end of each linkage, while a second rotatable axle is attached to an opposite end of each linkage.
