Title: Wire feeding device for a cable forming machine
Inventor: WECKEND SIEGFRIED
IPC: H01B13/00
Filed: 1968-03-08
Abstract: 1,220,185. Laying cable forms. ELEKTROMAT VEB. 8 March, 1968, No. 11539/68. Heading H2C.  A disc 2 carrying a plurality of wire guides 3 spaced around its periphery can be rotated in step-by-step manner by a crank 6 operating a pawl 4 engageable with the wire guides 3. During each step the guides 3 force a catch 18 to temporarily retract and at the completion of each step the catch 18 again enters between two guides 3 to locate the disc 2 such that a guide 3 is accurately located over a wire placing finger 16. The disc 2 moves against a torsion spring 23 and at the completion of a single revolution a cam 24 on the disc 2 forces the catch 18 rearwardly to a setting where it is retained by a pinion 21 engaging behind a lever 22. Rearward movement of the catch 18 permits the disc 2 to be returned to its start position by the spring 23, at which position the cam 24 will rock the lever 22 to release the catch 18 from its rearward setting. Although the crank 6 rotates continuously the pawl 4 is only effective when a solenoid 14 is energized to withdraw a spring- biased catch 8 out of engagement with the crank arm 5, a spring 13 then causing the pawl 4 to mesh with the guides 3.

The operand registers 1, 2 are connected to formers 32, 33 each of which form a representation of the value of the operand in a positional (e.g. decimal) notation. During additions, using the modular arithmetic unit 7, an analysis unit (74, Fig. 2, not shown) in the analysis system 18 provides the required outputs to registers 29 and 58 and a control signal to the arithmetic unit 7. During multiplications and divisions, using the arithmetic unit 7, the multiplier 38, or the divider 39, the sign of the result is derived from a modulo two adder (77, Fig. 2, not shown) in the analysis system 18 receiving the signs of the two operands. During shifting of the second operand by the shifter 40 the sign of the second operand is transferred to register 29 and an output of shifter 40 indicating whether an overflow has occurred is connected to register 58.
Patent GB-795790-A (GB)
Title: Improvements in or relating to the recovery of gold
IPC: C22B3/06
Filed: 1956-04-17
Abstract: Gold is separated from arsenical and sulpharsenical ores, concentrates and residues and roasted materials, which may contain also cobalt and/or nickel and/or iron, by treatment with one or more strong mineral acids followed by treatment in the same medium with an oxidizing agent supplied as such or produced in situ, the redox potential of the medium being measured, and maintained during the oxidation treatment at such a value that the gold is oxidized and solubilized.  Thereafter any solid residue is separated and gold recovered from the solution.  Mineral acids referred to are a mixture of sulphuric and nitric acids, hydrochloric acid and sulphuric acid. Suitable oxidizing agents are chlorine (which may be produced in situ by the addition of aqueous hydrochloric acid or sodium chloride to a sulphuric acid mixture or the addition of sodium chlorate to a hydrochloric acid mixture) and sodium or calcium hypochlorites, and the salts may be added as aqueous solutions.  It is preferred to employ a temperature of about 70 DEG  C. and an acidity greater than normal. When using a mixture of sulphuric and nitric acids it may be necessary, e.g. when using chlorine as oxidizing agent, to remove some of the arsenious oxide before effecting solubilization of the gold: in this case the residue of metallic arsenides which remains insoluble may be separated from the liquid, arsenic removed therefrom by suitable means such as hot water washing, and the solids resuspended in the liquid for completion of the solubilization after restoration of the redox potential.  If, however, hydrochloric acid or sodium chloride are used as oxidizing agents with sulphuric and nitric acids, the gold is solubilized before the arsenic is oxidized. After oxidation the liquor may be neutralized, e.g. with lime or calcium carbonate, with continuous maintenance of the redox potential above the level at which gold reprecipitates and with pH measurement. Thus with the solution from an ore containing iron and cobalt, and after obtaining an Fe/As ratio of about 1, the neutralization should continue until ferric arsenate is precipitated, then gold can be separated by adding sodium sulphide or iron or, as described in an example, by adsorption on charcoal.  Any silver present may be recovered by passing the gold-free solution over copper or iron. In examples: (1) a roasted speiss containing cobalt, nickel, iron and arsenic was reacted at 90 DEG  C. with hydrochloric acid and aqueous sodium chlorate added; and (2) smaltite containing cobalt, nickel and arsenic was reacted with a mixture of sulphuric and nitric acids and chlorine added as oxidizing agent.  Specification 795,793 is referred to.
