摘要： An electric machine includes a stator, a rotor interacting magnetically with the stator, a housing surrounding the stator and rotor, and a hollow shaft provided for arrangement of the rotor and mounted on the housing. A radial fan is mounted rotationally fixed on the hollow shaft on the ventilation side. A section of a fan blade of the radial fan extends axially away from the housing to a greater extent than the hollow shaft. A guide element with radially extending plate is arranged in the hollow shaft, wherein the plate is arranged axially further away from the housing than the end side of the hollow shaft on the ventilation side. An inner coolant flow can thus be delivered from the section of the fan blade out of the hollow shaft through a passage between the end side of the hollow shaft on the ventilation side and the plate radially outwards.

摘要： Elastically bendable elongate material with two free ends for stretching an opening edge of an opening of a flexible container. The elongate material, through elastic bending, is brought from a non-use position, in which it is not stretching the opening edge, into an insertion position, in which it is pretensioned and seeks to adopt the non-use position. In the insertion position it is inserted into the opening where it is brought into a use position in which it is pretensioned and seeks to adopt the non-use position such that the opening edge is stretched in a dimensionally stable manner, the free ends of the elongate material are at a distance from each other and between them hold a portion of the opening edge tensioned in a straight line, and a dimensionally stable stretching occurs only in the region of the opening while the rest of the container remains flexible.
