Abstract: An enclosed-ventilated electrically excited synchronous machine includes a shaft and a rotor which is non-rotatably positioned on the shaft. The rotor includes a plurality of pole bodies which project radially outwards. The pole bodies have each an exciter coil and form in their entirety a rotor winding, with each pole body having an end face formed with a coil winding head. A protective element is provided on the coil winding head to protect the coil winding head against abrasion.

Abstract: A strip ejector removes a longitudinal test strip (12), which has at least one test field for wetting by a fluid, from a measuring device that optically or amperemetrically measures such test strip. The ejector includes a clamping jaw holder (14), and at least two clamping jaws (18) arranged on the clamping jaw holder at a distance from one another. The jaws are moveable relative to one another between a freeing position in which the spacing between their clamping surfaces is larger than the width of a test strip (12), and a clamping position in which their clamping faces respectively engage parallel edges (22) of the test strip (12). An actuating element (24) moveably supported on the clamping jaw holder (14) has at least one control surface 30 arranged at an angle to the movement direction of the actuating element.
