Title: Threading-in parallel ends
IPC: D01D10/04
Filed: 1952-10-18
Abstract: Apparatus for use in an installation in which artificial threads pass through two sets of rollers at some distance apart comprises a suction-type thread collecting device 4 mounted on a rod 13 situated between the sets of rollers. A collecting device 4 may be provided under each thread, or one device may be moved along the rod as required. If a thread breaks it is guided to a notch 6 of a collecting device 4 and sucked into an air discharge line 8 leading it to a waste receptacle. The thread is then led over guides 9, 10. A thread near to the broken thread is guided over guides 9, 10 and under a guide 11 the broken thread is then connected to this <PICT:0720648/IV (a)/1> thread and is carried along by it, a knife 12 cutting the loose end when the point of connection of the yarns has passed the knife. The threads are subsequently removed from underneath guide 11. The method can be applied to threading-in the threads when starting the installation if one yarn has first been passed between the rollers.

Title: Two-stage pressure leaching process for zinc and iron bearing mineral sulphides
IPC: C22B19/00
Filed: 1976-10-22
Abstract: Direct pressure leaching of zinc and iron containing mineral sulphides in dilute H2SO4 is carried out in a two-stage countercurrent process in which finely divided sulphides are leached in a first leaching stage with solution from the second leaching stage to produce a first stage leach solution containing a high zinc concentration and low iron and H2SO4 concentrations.

The acid and sulphides concentrations in each of the first and second leaching stage is controlled such that (1) sufficient acid and sulphides enter the leaching circuit to ensure that the final leach solution exiting from the first leaching stage will contain sufficient dissolved zinc, e.g., 140-180 g.p.l., to make it suitable for treatment by electrolysis for recovery of zinc therefrom, (2) the quantity of sulphides entering the first stage leach is in excess of the quantity required to react with all available acid in the solution recycled from the second leaching stage and (3) the quantity of free acid entering the second leaching stage is in excess of the quantity required to react stoichiometrically with all acid reactive constituents in the residue passed from the first leaching stage to the second leaching stage.
