Title: A Method of Recovering Non- ferrous Metals From Their Sulphide Ores
IPC: C22B5/02
Filed: 1980-03-06
Abstract: A method of recovering a non- ferrous metal from a sulphide ore of the metal utilises a metal extraction circuit from which said non-ferrous metal or its sulphide is continuously extracted at an elevated temperature. The method comprises the steps of forcibly circulating a molten sulphide carrier composition 11 through the extraction circuit and introducing the sulphide ore into the molten carrier composition at an ore receiving station 10 so that the ore is dissolved in or melted by the composition 11. The molten carrier composition containing said ore is then contacted with oxygen at an oxidation station 15 so as to oxidize at least part of the ore and/or the molten carrier composition, heat generated during the oxidation step being recovered by the molten carrier composition 11 and being transmitted thereby to endothermic sites in the circuit. The metal to be extracted is either recovered at the oxidation station 15 by oxidation of the sulphide ore to produce the metal or alternatively is recovered from a reduced pressure vessel 13 either as a volatile sulphide of the metal or after reduction of the ore to the metal by the oxidized carrier composition 11. <IMAGE>

Patent GB-2087827-A (GB)
Title: Producing a stack of nested layers of cylinders
IPC: B65G57/30
Filed: 1980-07-08
Abstract: Wrapped cylindrical rolls of sweets (R) are lined up one behind another in a row at a stacking station so as to be parallel but not co-axial, lifting bars (26) then raise the row so that it becomes latched in an elevated position on pivotal supporting flaps (27, 28). A second row of rolls is subsequently raised by the bars (26) so as to displace the first row upwards, supporting the first row roll-on-roll, and become latched in the elevated position by the flaps (27, 28). An end cylinder of the first row is displaced laterally by a pushing blade (36) causing cylinders of the first row to nest between cylinders of the second row. Third, fourth, etc. rows are brought in beneath the second row and are elevated so that the stack is built up progressively from beneath, initially in roll-on-roll fashion but subsequently with every alternate row being nested by laterally displacing the end cylinder of that row. The stack is removed, for boxing, by sliding all but the bottom row of rolls axially away from the bottom row without altering the positions of the removed rolls relative to one another. The amount by which the end cylinder is laterally displaced is governed by limit switches. <IMAGE>

Patent GB-2058163-A (GB)
Title: Exhaust Dyeing
IPC: D06B23/28
Filed: 1980-09-01
Abstract: The dyeing of textiles is controlled by repeatedly determining the optical density of the dye liquor and adjusting the rate of exhaustion of dye onto the material so that the factor   <IMAGE> where A1 and A<2> are optical absorbances of the liquor respectively at successive times t1 and t2, is kept constant at least until nearly the end of the process, when the factor may be allowed to increase. The optical densities are measured at a number of wavelengths and by use of a computer the factor is moved for control purposes which, at the particular stage in the dyeing process, gives the greater value of the factor Q. The wavelength giving the optimum value of Q may vary during the dyeing process. The invention also contemplates the use of optical density cells of different lengths and the use of one apparatus to control dyeing operations in a number of dyebaths.

Title: Method and device for removing flashes and barbs
Inventor: VASILIEV VLADIMIR ALEXEEVICH
IPC: B24B31/112
Filed: 1980-11-28
Abstract: A method consists in generating an alternating magnetic field penetrating through a reservoir containing the parts to be treated and working elements. The alternating magnetic field sets in motion the working elements made of a material capable of interacting with that magnetic field thus leading to strokes between the working elements and the parts to be treated in the course of that motion. A device for implementation of the method comprises a means for generating the alternating magnetic field, a cooling agent being as well fed, if necessary, to that reservoir. That permits to intensify the process of removing the flashes and barbs, to improve the quality of treatment and to enlarge the assortment of treated parts.
