Abstract: 979,185. Endless and reciprocating conveyers. ALFRED HERBERT Ltd. Aug. 12, 1963 [May 12, 1962], No. 18358/62. Heading B8A. Apparatus for transferring a succession of articles from a loading station 1 to an unloading station 9 includes a shuttle table selectively movable forwardly or backwardly through a plurality of intermediate stations 2-8. The table comprises an endless chain of interconnected platforms 100 having pegs 101 on which the articles 102 can be placed. At least one of two sprocket wheels 103, 104 is driven by a reversible motor. A loading arm 106 and an unloading arm 107 can swing about vertical axes. A contact LS1 is closed and a linked contact LS1(NC) (not shown) is open when the loading arm 106 has been moved to a position over the loading station 1. The contact LS1 is connected in series with a counting uniselector winding by which one digit is added to the reading of the counting uni-selector to indicate the total number of articles on the table, when the contact LS1 is closed. A position uni-selector winding is controlled by a contact LS3 which is normally open. This uni-selector indicates the station at which the article nearest to the unloading station is located. The contact LS3 is closed during each forward movement of the table from one position to another, and one digit is added to the uni-selector's reading. Each time the unloading arm 107 is positioned over the unloading station 9, contacts LS2 and LS2(NC) (not shown) are operated, and a digit is subtracted from each of the counting and position uni-selectors. Control means to operate the driving motor in response to the operation of the loading and unloading arms 106, 107 provides that, prior to operation of the loading arm 106, the shuttle table, except when empty, is moved backward until the article nearest the loading station 1 is at intermediate station 2, and that immediately prior to the operation of the unloading arm 107, the table is moved forward until the article nearest to the unloading station 9 is at the unloading station. The apparatus is primarily concerned with machine tools and serves to provide a reservoir of compoents for a machine tool or between two machine tools, operable at different speeds, or for enabling one of the machines to be stopped for re-setting or a breakdown, while permitting the other machine to carry on either supplying components to the table or receiving components from the table.

Abstract: A process for producing copper from a solution containing copper sulphate comprises reacting said solution with sulphur dioxide and hydrogen cyanide at a temperature below 90 DEG C., under a pH below 7, employing at least 60% of the stoichiometric amount of hydrogen cyanide and at least the stoichiometric amount of sulphur dioxide required for the reaction, to precipitate copper present as cuprous cyanide and form sulphuric acid, separating the cuprous cyanide precipitate from the sulphuric acid, and reducing the cuprous cyanide with hydrogen to form copper metal and hydrogen cyanide.  The copper sulphate solution may be obtained from oxidized copper ores, tailings, overburden from such ores and copper scrap by leeching and may contain from 0-5 to 50 grams of copper per litre.  The reduction of the cuprous cyanide may be with excess hydrogen and at up to 5 atmospheres and a temperature of 190 DEG -600 DEG C. The product of reduction of the cuprous cyanide may be passed through water or through liquors to absorb hydrogen cyanide and the hydrogen recycled.ALSO:A process for producing copper from a solution containing copper sulphate comprises reacting said solution with sulphur dioxide and hydrogen cyanide at a temperature below 90 DEG C., pH below 7, employing at least 60% of the stoichiometric amount of hydrogen cyanide and at least the stoichiometric amount of sulphur dioxide required for the reaction, to precipitate copper present as cuprous cyanide and form sulphuric acid, separating the cuprous cyanide precipitate from sulphuric acid and reducing the cuprous cyanide with hydrogen to form copper metal and hydrogen cyanide.  The copper sulphate solution may be obtained from oxidized copper ores, tailings, overburden from such ores and copper scrap by leaching and may contain from 0.5 to 50 grams of copper per litre. The hydrogen cyanide may be obtained at least in part from the reaction of air, hydrocarbon gas and ammonia at about 1000 DEG  C. in the presence of a catalyst; thus the hydrogen cyanide product is more pure.  In a continuous process, after filtration of the cyanide the filter is blown with an inert gas or air to remove hydrogen cyanide and sulphur dioxide. Alternatively the stripping may be in two stages using first an inert gas and then air.  The hydrogen cyanide and sulphur dioxide are absorbed in water and returned to the reaction with copper sulphate leach solution and the strip liquor to a leaching stage. The hydrogen cyanide and sulphur dioxide may be liquefied.  The product of reduction of the cuprous cyanide may be passed through water or through liquors to absorb hydrogen cyanide and the hydrogen recycled. The hydrogen cyanide solution, so formed, may be stirred with gas or distilled and the hydrogen cyanide recycled.
