Abstract: 225,680. Cheetham, H. Oct. 24, 1923. Liquids, treating with; designs, producing; crape effects, producing.-Cotton fabrics are mercerized to impart to them a permanent firm transparent sand-paper finish, or organdie finish by impregnation with zinc chloride solution of 82‹- 104‹ Tw., drying at 210‹-212‹ F., passing through cold acid, rinsing, and drying. The cold acid bath may be acetic, formic, lactic, tartaric, or citric acid, of 9‹ Tw. or sulphuric, hydrochloric, or nitric acid, of 2‹ Tw. The excess of acid is extracted bv suction sockets before the fabric enters the cold water. The drying at 210‹-212‹ F. may be effected by hot air, or by passing the fabric over steam-heated cylinders having smooth or enamelled surfaces. For producing a permanent soft silk-like transparent effect, the fabric is mercerized with strong alkali before or after the treatment described above. Watered or crape effects may be produced by engraving the steam heated cylinders, the engraved parts preventing the action of the zinc chloride on the fabric, or the fabric may be printed with a resist of gum or starch thickening and then printed or impregnated with the zine chloride.

Title: Extrusion head for production of nets of plastics material
IPC: B29C48/05
Filed: 1960-08-05
Abstract: 928,954. Extruding plastic nets. NORDDEUTSCHE SEEKABELWERKE A.G. Aug. 5, 1960 [Jan. 13, 1960], No. 27151/60. Class 87(2). An extrusion head for producing knotless extruded nets of plastics material has two chambers 10, 11 rotatable independently of one another and provided with nozzles 12, 13 respectively, chamber 10 being mounted axially within the space enclosed by chamber 11. In the embodiment illustrated in Fig. 1, both chambers 10, 11 are connected to a common worm press (not shown) by means of a pipe union 14. The inner chamber 10 is driven by means of an axial shaft 15 which passes through the pipe union 14 and engages by way of vanes 16 in grooves 17 in the wall of the chamber 10. In order to regulate the flow of plastics material M into the inner chamber 10, the driving shaft 15 is axially adjustable and provided with a valve body 18 co-operating with a valve seat 19 formed on the upper edge of the wall of the chamber 10. By this means the relative diameters of the threads emerging from the nozzles 12, 13 are controlled. The diameters of the threads may be varied by varying the worm speed or the delivery speed of the completed net. The chambers 10, 11 are driven by means of gear wheels 21, 22 respectively so as to execute an opposed rotary movement relative to one another, preferably rotating at the same speed but in opposite directions. In a second embodiment, Fig. 3, the driving shaft 15 is hollow to feed plastics material M 1  from a second worm press (not shown) to the inner chamber 10. The driving shaft 15 in this case is advanced to such an extent in the extrusion direction that its valve body 18 abuts against the valve seat 19, thus preventing material M from the first worm press from entering the inner chamber 10. Materials M and M 1  may be different thermoplastic materials or the same material but of different colours. The two chambers 10, 11 may be fed from only one worm press, however, if the valve 18, 19 is open and the mouth 15a of the hollow shaft 15 closed, for example by means of a stopper. It is also possible, by having the valve 18, 19 open to cause the plastics materials to mix in the inner chamber 10, a mixture of materials M and M 1  thus being extruded from this chamber.
