    Abstract: A gear is disclosed for converting a rotary motion into a translation motion. The device has a rotary drive and a motion transmission member held for movement along a guide. The motion transmission member (5) is divided longitudinally into at least two parts (7,8) as viewed in the direction of the guide (6). The parts (7,8) are provided with a toothing (9). They interengage the guide (6). Outside the guide (6), the parts (7,8) are deformable transversely to the direction of the guide and are each guided separately. The parts (7,8) are connected to the drive (1) in a geared manner by means of a screw coupling (10). The advance in the art is seen in simplified structure of the mechanism. Besides, the mechanism provides low friction and a small mass.

    Abstract: Variable electrically motorized drive mechanism for gates or similar structure close-off devices that can be installed for the purpose of an assembly operation that is as heavyduty as possible and without fine adjustments, for which purpose the gate is provided with controls that essentially comprise a position detector, a memory, and a referencepoint indicator, the last of which is positioned between the gate-panel limiting positions and outside of any stop positions or defines a corresponding gate-panel referencepoint position and synchronizes the position detector at each stroke such that the path that the panel is to travel along from the reference-point position into a particular desired position is dictated or monitored in accordance with a memory output that corresponds to the adjusted position. The system is accordingly continuously self monitoring and can synchronize itself when the motor is started up again after a power outage and possibly manual operation of the gate.

    Abstract: An actuator has a worm gear which drives a pair of flexible parts into a guide where they are united to form a rigid transmission member. The parts have interlocking teeth which cooperate with each other to transmit stresses in compression and tension along the transmission member. Because the parts are flexible in a direction transverse to the direction of the guide, they may be stored in a space-saving manner to the sides of the guide.
