Abstract: Apparatus for manufacturing bulky yarns employing flowing gaseous or liquid media by the false twist technique. It consists of a tubular yarn guide chamber and a lateral conduit for the fluid medium disposed perpendicularly to the axis of the guide chamber and opening into same tangentially to the internal wall thereof, the guide chamber being cylindrical and at the yarn inlet end having a drastically reduced cross-sectional area compared to the cross section of the remainder of the chamber. The fluid inlet is located immediately downstream of the yarn inlet end (in the direction of movement of the yarn) in the enlarged portion of the chamber. The latter narrows at a point downstream of the fluid inlet (in the direction of movement of the yarn) and subsequently opens into a tubular duct the internal wall of which contains groovelike recesses over at least part of its length.

Abstract: A tubular reactor with forced circulation of a heat transfer medium which flushes the outside of the reaction tubes in axial direction, the heat transfer medium being supplied to, and withdrawn from, the reactor wall uniformly through circular pipelines, and particularly the constructional shape of deflecting guide plate means arranged transversely to the direction of flow and having annular openings around the reaction tubes for uniform flow towards all the tubes of the nest of tubes.
