Abstract: An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.

Abstract: A device for detecting the rotational movement of an element which is rotatably seated around an axis, the device including a material measure that rotates about an axis of rotation. A first measuring graduation provided on the material measure and which scans along a first direction, which has a component along the axis of rotation and a second measuring graduation provided on the material measure, wherein both the first measuring graduation and the second measuring graduation surround the axis of rotation in a ring shape, and which can be scanned along the first direction and a second direction that is linearly independent of the first direction. At least three measuring heads, which are spaced apart from each other along a circumferential direction which surrounds the axis of rotation, are assigned to each of the first measuring graduation and the second measuring graduation for scanning the first measuring graduation and the second measuring graduations.

Abstract: A calibration device for a parallel kinematic manipulator having a base unit and a manipulator platform movable with respect thereto, the manipulator platform being connected to the base unit via a plurality of joints and a plurality of variable length actuators. The calibration device for measuring n deviations in order to determine m unknowns includes a test workpiece that is mountable in a definite spatial position with respect to the base unit and has I=m/n measuring mandrels. The calibration device also has a probing unit attached to the manipulator platform, and including n probing subsystems, the probing subsystems each including a distance measuring device for measuring the spatial position and spatial orientation of the measuring mandrels on the test workpiece.

Abstract: A measuring system for determining the position of two machine components that are movable in relation to each other, having a measuring graduation extending in a measuring direction, a support body supporting the measuring graduation, a scanning device scanning the measuring graduation, a mounting base for fastening the scanning device on one of the components, and a securing device for fixing the mounting bas in place in a prescribed position with respect to the support body. The securing device includes a base body that is supported on at least two areas of the support body that are spaced apart from each other with respect to the measuring direction and a guide element. A guide track is provided in the support body, wherein the guide element interlockingly engages the guide element and in which the guide element can be clamped in place in that the guide element is displaced in relation to the base body by a connecting element.

Abstract: A device is disclosed for connecting the edge region of a covering material (2) for vehicle seat upholstery to a mounting (3).

Abstract: A diaper construction is disclosed including a pair of elastic leg seal members extending longitudinally of the diaper adjacent each side edge thereof, the leg seal members being operable between expanded and contracted conditions, respectively, and moisture-responsive devices initially maintaining the leg seal members in their expanded conditions, whereby when the diaper is worn by a user and the leg seal members become moisturized, the moisture-responsive devices are operable to release the leg seal members, whereby the leg seal members contract into sealing engagement with the user's leg.
