1429838 Textile treating apparatus AHIBA AG 3 Aug 1973 [12 Dec 1972] 36912/73 Heading D1L Apparatus for treating textile materials (e.g. hank, fabric or fibre samples) comprises a bucket 3 postioned in a trough 1 of heating fluid 2, an inset 5 disposed centrally in the bucket and containing the textile material 10 above its perforated bottom 7, and means for causing a treating liquid 11 (e.g. a dye) to flow along a path which is parallel to the longitudinal axis of the inset 5 for at least part of its flow path and through the textile material, the flow means including a magnetic bar 4 disposed in a space P below the inset 5 and rotated about axis a-a by a magnetic drive means, not shown, disposed outside the bucket and vanes 9 [Fig. 2] running parallel to the axis of and attached to cylindrical wall 6 of the inset 5. The vanes 9 may extend at an angle to the axis of the inset in a helically curved line where turbulent rather than laminar liquid flow in the spaces 12 is required. Displacement member 13 may be provided to reduce the quantity of treating liquid required. In an alternative embodiment [Fig. 3] the inset is in the form of a perforated cylinder 33 around which the textile material is wound and the liquid is circulated by an impeller 25 connected via shaft 24 to a permanent magnet flange 23. On rotation of the impeller 25 liquid is caused by guide assembly 26 to flow into the annular space 35' between the inset 33 and the bucket 21, through the material and into a second annular space 35 provided between the inset 33 and a pressure tube 31 mounted inside and concentrically of the inset. From annular space 35 the liquid flows back to expansion chamber 40 via groove 36 provided in the underside of a pressure ring 32. A suction ring 27 having stationary flow guide vanes 30 is provided at the bottom of expansion chamber 40 above and surrounding the impeller assembly. A further embodiment [Figs. 5 and 6, not shown] combines the impeller and suction tube ...
