  • Patent number: 4655441
    Abstract: The invention relates to a device for the transverse and/or longitudinal machining of wood workpieces having at least one clamping table which is rotatable or tiltable about at least one pivot axis. The clamping table is connected to a drive gear of a servo drive positioned in the pivot axis. So that the servo drive of the device can also operate free from play during a machining operation, an output gear wheel having front and rear tooth flanks and connected to a servo motor via a drive gear and a sprocket wheel are secured on an output shaft. The sprocket wheel is in engagement with a tension chain which exerts a torque on the output shaft in a predetermined rotational direction, one free end of the tension chain being connected to a controllable fluid cylinder so that in any rotational direction of the servo motor or of the output shaft, either front or rear tooth flanks of the output gear wheel are constantly in contact with corresponding flanks of the drive gear.

  • Patent number: 4234241
    Abstract: A 45.degree. rotary mirror illuminates a detector through an optical colling system and while facing downwards picks up a direct or primary line scan of objects located below in the plane of scanning. While facing upwards, the rotary mirror picks up a secondary line scan indirectly from below by reflection from a non-revolving plane mirror at an acute angle to the axis of rotation of the rotary mirror, which angle corresponds to the base angle of stereo scanning when the primary line scans are correlated with corresponding secondary line scans that respectively precede them by an interval corresponding to the travel time of the movable craft upon which the line scanner is carried along a base line distance determined by the inclination of the non-revolving plane mirror. That inclination is adjustable about a hinge axis perpendicular to the direction of travel of the carrying aircraft or spacecraft.
