    Abstract: Fixed blading for an axial compressor constituted by a succession of blades fixed on at least one annular wall and a method of operating the same. Fluid passing through a passage between adjacent blades is drawn into a suction opening and the pressure at the suction opening is maintained substantially equal to the flow static pressure in the passage.

    Abstract: In order to corrugate or pleat between forming rolls sheet metal irrespective of its ductility while containing the blister formed at the end of the corrugation or pleat in the course of formation, the sheet is heated locally, at a short distance upstream of the rolls, to a temperature capable of rendering the sheet ductile. The rolls are protected against harmful heating by the distance between the heating region and the forming rolls.

    Abstract: To enable visual observation and X-ray analysis of a sample irradiated by an electron beam, a heat-protective assembly overlying a sample-supporting surface includes an enclosure with a central window for the electron beam, a surrounding annular window for light rays and a pair of lateral windows for X-rays emanating from the sample. An inner shield has a frustoconical body, with generatrices converging toward the supporting surface, which gives passage to both the light rays and the electron beam while screening an area surrounding the annular lighttransmissive window of the enclosure without, however, blocking the passage of the X-rays. A set of deflecting plates for the electron beam is mounted on the inner shield, between its frustoconical body and a diaphragm forming the central window, in a zone between the paths of the light rays and the electron beam.
