Abstract: The invention relates to a corrugated pipe of thermoplastic polymer material for use as fluid line with at least one polymer layer, comprising closed geometric outer contours which are spaced at an interval from each other in the axial direction of the pipe and which define a corrugation on the pipe jacket in at least one radial angular sector in axial, longitudinal direction one behind the other. The closed geometric outer contours are designed in such a manner that two jacket lines of the pipe jacket surface, which lines are approximately opposite one another, are free of corrugations and that these jacket lines extend in the longitudinal direction of the pipe (FIGS. 1b-1d).

Abstract: Branch shears (1) having two blades (11, 12) that are movable in relation to each other, of which one blade (11) is rigidly connected with a housing (2) and the other blade (12) can be moved by an electric motor (5) via a threaded spindle (8), a threaded nut (21) arranged on the threaded spindle and a rod assembly connected to the threaded nut. A control switch (41) having two reversing switches (42, 43) connected to the circuit of the electric motor (5) is provided. In addition, a control link (51) is attached to the spindle nut (21), onto which the operating cams (53, 54, 55) interacting with the reversing switches (42, 43) are formed. With the aid of the control switch (41), it is possible to stop, continue or reverse the movements of the pivotable blade (12) at any time in a simple manner, thus the movements of this blade can be controlled as desired. In addition, it is ensured that the branch shears (1) will always open automatically by the force of the electric motor (5) if the control switch is released.
