Abstract: An articulating robotic arm for minimally invasive surgery, comprising a proximal arm segment extending along a longitudinal axis of the robotic arm and a distal arm segment connected to the proximal arm segment, pivotable about a pivot axis orthogonal to the longitudinal axis. The distal arm segment comprises a pinion segment formed with pinion teeth arranged about the pivot axis in the form of a pinion. A rack element is arranged on the proximal arm segment such that the rack element is movable in the longitudinal direction of the rack element parallel to the longitudinal axis by means of a translation, and rack teeth formed on the rack element are engaged with the pinion teeth so that a movement of the rack element in the longitudinal direction via the rack teeth and the pinion teeth is converted into a rotational movement of the distal arm segment about the pivot axis, and so that the distal arm segment pivots relative to the proximal arm segment about the pivot axis.

Abstract: The disclosure relates to a composition containing a base material and metal effect pigments (1) contained in the base material, wherein the metal effect pigments (1) are provided with a three dimensional shape selected from the following group: cube, pyramid having triangular outer surfaces, and tetrahedron. Furthermore, metal effect pigments (1) and a method for producing metal effect pigments (1) are provided.

Abstract: The invention relates to a machine assembly 100 for use in a manufacturing machine 1000, in particular in a horizontal orientation of an axis of rotation D in a horizontal manufacturing machine, comprising a workpiece fixture 30 which is mounted on a fixture carrier 4 and has a first side 31 and a second side 32, and a first and a second tool holding fixture 10, 20, wherein the first tool holding fixture 10 is arranged on the first side 31 of the workpiece fixture 30 and the second tool holding fixture 20 is arranged on the second side 32 of the workpiece fixture 30. According to the invention it is provided that the workpiece fixture 30 has a main spindle 33 with an axis of rotation D running from the first to the second side 31, 32, and the main spindle 33 is designed for holding a workpiece along the axis of rotation D.
