    摘要: This invention relates to an apparatus for false twisting synthetic filament yarns, which apparatus is in the form of an air rotated nozzle having tangential inlet bores and two central outlet bores. The twisting chamber is set at an angle of 2.degree. to 40.degree. to the draw-off direction of the filament. The special advantage of this apparatus according to the invention is that it ensures smooth movement of the filament outside the twisting chamber.

    摘要: An apparatus is described which serves for a pyrometallurgical processing of fine-grained solids suspended in high-oxygen gases, comprising a generally horizontally extending cylindrical vessel and a combustion shaft, which communicates with and vertically opens into the vessel which is provided with a gas outlet opening and with an opening for discharging molten material. An almost complete separation of the molten particles is effected in that the mouth of the combustion shaft tangentially opens into the vessel at the entrance of a spiral-shaped entrance passage, which opens into a discharge slot, which is formed in the shell of the vessel and which in the lower portion of the shell of the substantially cylindrical vessel extends substantially parallel to the longitudinal axis of the vessel.

    摘要: A mixing insert of solid material into which intersecting channels are drilled is particularly suitable for use as a static mixer for highly viscous liquids. The insert provides a high quality of mixing while withstanding pressure differences of more than 10.sup.7 Pa along the mixer. If the insert is rotated, static and dynamic mixing properties are superimposed on each other in the mixer. Either forward transport of the materials or return for remixing can be particularly promoted according to the sense of rotation and form of the external channels, which must be partly open.

    摘要: An injector (12) for sucking in environmental air and for injection into the combustion chamber (12) of a torch burner (11) by means of a driving fluid (14) standing under excess pressure, has an air induction opening (15), a flow channel (16) and injection openings (17) through which the driving fluid (14) is blown into a mixing region (19) where it mixes with induced air. The flow channel (16) has a diffusor region (18) ajoining the mixing region (19) in the flow direction and has an outlet opening (20) for the mixture of air and driving fluid. In accordance with the invention, injection openings (17) open into a dead flow space (22) from which spray jets (23) are directed into the mixing region (19).

    摘要: In order to conduct thoroughly pre-mixed hot gas into a ring spinning nozzle by a rotational flow in such a manner that sufficient quantities of hot gas are available for drying the filaments situated on the inside without causing backflow and without any significant movement of the filaments by turbulence, an annular chamber with tangential inlet is placed around the ring spinning nozzle. The internal wall of the chamber is separated from a circular chamber by equalizers in its upper region while on its underside it is separated from the spinning chamber by equalizers and metal gauzes at the level of the lower edge of the spinning nozzle. The circular chamber is also separated on its underside from the spinning chamber by equalizers and metal gauzes.
