  • Patent number: 6519998
    Abstract: A radial press comprises two press yokes and eight crimping members. The yokes are arranged on a plane that is perpendicular to the press axis and are located diametrically opposite the press axis and can be moved towards each other in a straight line by means of a drive unit, whereby the direction of movement is perpendicular to the press axis. At least one part of the crimping members that are disposed in the yokes has slide surfaces that respectively cooperate with a control surface of one of the yokes or an adjacent crimping member in such a way that all of the crimping members can be moved in a uniform manner onto the press axis when the press yokes move closer to each other. Two crimping members arranged perpendicular to the direction of movement of the at least one movable press yoke are divided into two segments.

  • Patent number: 5029398
    Abstract: A multiple-coordinate measurement sensor has an improved, high degree of precision of measurement, even at higher measurement speeds. Three multiple-axis guide systems (7,13,19; 8,14,20; 9,15,21) are arranged in parallel to each other. Length-measuring devices (6) and zero-point and contact-force generators (5) of each system are fastened to the reference base (1), and the devices (5,6) detect the positions of the guides (7,8,9) which are closest to the reference base (1).
