Patent EP-0601614-A1 (EP)
Inventor: ENOCH GERRIT DERK
IPC: C02F1/20
Filed: 1993-02-04
Abstract: The invention relates to a method for purifying a fluid flow, in particular waste water, from which floating dust has been removed, comprising the steps of:
     a) removing volatile components from the flow (2,3);   b) subjecting the flow to an oxidation treatment (4);   c) separating the flow into a first sub-flow containing monovalent ions and a second sub-flow containing heavy metals (5);   d) removing fluorides from the first sub-flow by precipitation by means of a calcium salt (8);   e) converting the monovalent ions from the first sub-flow into corresponding acids and bases (10); and   f) recovering the heavy metals in metallic form from the second sub-flow (13).   
     The different steps of the method can be performed in practice in various ways but a method is preferred wherein the volatile components are removed by a steam stripping process, the oxidation takes place by means of ozone and UV radiation, separation of the flow is performed by means of reverse electrodialysis, the fluorides are separated by precipitation with calcium chloride, the sub-flow containing the monovalent ions is separated into acids and bases by means of bipolar membrane techniques and the heavy metals are precitpitated electrolytically. 
     The invention further relates to a system of devices for performing the method according to the invention. 
     It is likewise possible to apply one or more of the different steps alone or in combination with a conventional waste water purification process.

Abstract: A real time three-phase analyzer stores digitized values of the signals of the three-phase circuits in memory so that they may be addressed according to circuit and sample number. Positive, negative and zero phase sequences are developed without the need for trigonometric calculation by combining samples offset in memory by a number of samples approximating 120°. That number of samples may be determined for an arbitrary frequency of the three-phase system by identifying zero-crossing points of one such signal and assuming the number of samples equates to 360° of phase of that circuit. The phase sequence of the three circuits necessary for the calculation of the positive, negative and zero phase sequences may be determined by comparing the relative position of positive going zero-crossings for each of the three circuits.

Abstract: The spinning apparatus comprises two centrifugal spinning cans (7, 8) fed alternately by two conduits (5, 5'; 6, 6') connecting a drawframe to these spinning cans (7, 8) and commencing at a junction located at the exit of a common conduit (3). Each conduit (5, 6) comprises a set of nozzles (22, 23) intended for generating a helical flow. Two storage bobbins (9, 10) are arranged between the two parts of the conduits (5, 5'; 6, 6') in order to receive the spun thread in the cans (7, 8). Two pneumatically actuated pushers (11, 12) are intended for nipping the thread against the storage bobbins and at the same time interrupting the increase in the twist in the thread. Since, simultaneously with the actuation of one of the pushers (11, 12), the set of nozzles (22, 23) arranged in the conduit (5, 6) which is to receive the thread generates a helical air flow in this conduit at the moment when the spinning can is changed, the thread is sucked into this conduit. Because it no longer receives any twist after the nipping of the thread, the force thus exerted makes it possible to separate it and to direct the bundle of fibres (4) into the new conduit where it receives a twist. Another injector (20) is arranged at the exit of the drawframe (1, 2) in order to impart the sufficient cohesion of the fibres making it possible to maintain uniformity and is actuated with a predetermined delay in relation to the nozzles (22, 23) in order to assist the release of the thread and the change of conduit. <IMAGE>
