Abstract: -a-ABSTRACT OF THE DISCLOSURE     This invention relates to a process to recover non-ferrous metal such as zinc, lead, copper, and precious metals either directly from their ores or from bulk or dirty con-centrates produced from their ores.  The development of a variable metallurgical process which would be capable of treating low grade concentrates, bulk concentrates or the ore directly is of interest for massive fine grained sulphide ore found throughout the world.  Thus the present specification discloses a method for recovering zinc from sulphidic ores and concentrates comprising the following consecutive steps: a) roasting said material in a subdivided form in a fluidized bed reactor at a temperature from 620 to 700°C, with 20 - 60% excess air or oxygen over the stoichiometric for an average retention time of over 1 hour and at a superficial special velocity of the gas within the bed of 25 - 150 cm per sec at reactor temperature resulting in an atmosphere comprising SO2, SO3, water vapour, and remaining O2 and N2 from the air, to obtain a calcine containing the zinc primarily as sulphates and oxysulphates and most of the iron as hematite; b) leaching said calcine with water or dilute sulphuric acid solution at a temperature below 80°C in such a manner that the sulphates, oxysulphates, and oxides of zinc are leached out in part from the calcine into the water or dilute sulphuric acid solution; c) subjecting the leach pulp resulting from step (b) to a liquid-solid separation step to yield a leach solution suitable for purification-metal recovery steps for zinc;     - b -d) leaching the solid residue resulting from step (c) with hot, strong sulphuric acid solutions, at a temperature above 80°C but below the boiling point of the solution and with sulphuric acid solution stronger than used in step (b), in such a manner that most of the zinc ferrite and unreacted sulphide of zinc are converted to the sulphates of iron and zinc which dissolve in the leach solution; e) subjecting the pulp resulting from step (d) to a solid-liquid separation step to obtain a leach solution containing said sulphates of iron and zinc; f) recycling said sulphates of zinc and iron obtained in step (e) in part into said fluidized bed reactor in a subdivided form to convert the sulphates of iron to hematite, SO2 and SO3; g) washing the solid residue resulting from step (e) with water; h) subjecting any pulp resulting from step (g) to a solid-liquid separation step to obtain a washed leach residue and a wash liquor containing zinc and iron sulphates and sulphuric acid; and i) recycling said sulphates of zinc and iron resulting from step (h) in part to step (b) and/or in part to the said fluidized bed reactor in a subdivided form to convert the sulphates of iron to hematite, SO2 and SO3.

Abstract: ABSTRACT OF THE DISCLOSURE:                 A coupling arrangement comprises a first coupling part and a second coupling part which can be connected to and disconnected from the first coupling part. The first coupling part houses a longitudinally displa-ceable valve, and a sealing device prevents medium from leaking between the valve and the first and second coupling parts.  Between opposing surfaces on the outer surface of the valve and an inner wall in the first  coupling part there is a first sealing element.  The first sealing element prevents the medium pressure from reaching a surface area which, viewed in a radial direction, is located outside the opposing surfaces and is situated on the valve or adjoining the valve.  In this way, the medium pressure is prevented from acting on the surface area and occasioning a force which is directed counter to a lifting force on the valve.

Abstract: ABSTRACT OF THE DISCLOSURE A control system for a web-feeding machine used to provide a continuous supply of material having successive labels and registration marks printed serially thereon is disclosed.  The machine has an assembly for splicing the material from a ready web and the material severed from a running web wherein the response of the assembly after being actuated is delayed by a response time T.  The control system comprises a driving circuit having an input and an output electro-mechanically coupled to the splicing assembly actuated thereby in response to a signal applied to the input thereof, a scanner positioned adjacent the material to provide a signal in response to the presence of a registration mark, and an encoder for providing a fixed number of pulses proportional to a corresponding length of the moving material.          The control system also comprises a control circuit connected to the scanner, the encoder and the input of the driving circuit.  The control circuit counts the number of encoder pulses between successive scanner signals and then decrements from that number to zero and, responsive to a scanner signal, provides a time delay To preset to approximate the response time T and decrements to zero from a preset number D after the time delay To has expired. The control circuit also provides a splice signal SS and supplies a splice-command signal SC to the input of the driving circuit in response to the splice signal SS.  The machine accomplishes a splice-in-register after the splice-command signal SC has been applied thereto.

Abstract: ABSTRACT     A coal cleaning process for removing substantial mineral matter  from high ash-containing  coals  using  coal-derived liquid by using coal-derived liquid for agglomeration.   In the process, particulate coal is mixed with sufficient water to provide a flowable slurry, and coal-derived hydrocarbon liquid is intimately mixed with the coal-water slurry to provide agglomerated coal particles.   By screening the re-sulting coal-water-hydrocarbon liquid mixture, a portion of the coal containing increased mineral matter settles, and a coal-oil upper portion of agglomerated coal particles having decreased concentration of mineral matter is  removed and dried to remove water to less than about 25 W % remaining.          The cleaned and dried coal-oil material is advantageously fed to a coal liquefaction process  to produce hydrocarbon liquid  and  gas  products,  and a  coal-derived hydrocarbon liquid is recycled to the coal cleaning step to produce the agglomerated and cleaned coal particles.
