Title: New or improved method for the recovery of copper and nickel
IPC: C22B3/06
Filed: 1927-12-19
Abstract: 283,132. Chemische Fabrik Johannisthal Ges., and Trostler, F. Jan. 4, 1927, [Convention date]. Copper and nickel hydroxides, obtaining. - Copper and nickel are recovered from coppernickel alloys, matt or speiss by treatment as anode in a neutral or weakly basic electrolyte, e.g. common salt solution. Copper and nickel hydroxides are precipitated as mud which is then treated with a solution of a copper salt, preferably in excess and repeatedly, if necessary, until the nickel hydroxide goes into solution. In an example, Monel metal containing 70 per cent nickel and 30 per cent copper is cast into an anode and electrolyzed at normal temperature in a 10-15 per cent common salt solution to which a few drops of alkali lye have been added. The voltage may be 2.3 and the current density up to 350 amps. per sq. metre; if the alkali lye is omitted the current density should be 200-250 amps. per sq. metre until the solution has become alkaline. The temperature may alternatively be 80-100‹ U. The precipitate is treated with copper chloride or copper solution; the nickel goes into solution leaving copper hydroxide. The nickel salt may be crystallized out from the solution, or the nickel may be recovered from a chloride solution by electrolysis. Lead, when present in the alloy, remains with the copper, together with arsenic and sulphur. The copper oxide mud may be dissolved in sulphuric acid to give copper sulphate. Instead of copper salts, iron salts such as iron sulphate lyes may be used for separation of the electrolytic mud. Alternatively an acid may be used as solvent, e.g. hot sulphuric acid of strength 40‹ BÚ. when crystallized nickel sulphate is required, or hydrochloric acid when the nickel is to be recovered electrolytically. Numerical examples are given.

Title: Improvements in and relating to soldering metal articles
IPC: B23K35/00
Filed: 1957-11-07
Abstract: 825,317. Soldering. GENERAL MOTORS CORPORATION. Nov. 7, 1957 [Nov. 13, 1956], No. 34704/57. Class 83 (4). [Also in Group II] In soldering metal articles at least one of which consists of aluminium or aluminium alloy, the articles are immersed in a solution comprising an alkali metal hydroxide and an alkali metal zincate dissolved in a solvent to clean the aluminium or aluminium alloy article and plate a film of zinc thereon and are then immersed in molten solder by passing them through an interface between the solution and the solder. A bath 12 is prepared comprising a molten low-melting point solder 10 beneath a cover layer 14 having a boiling- point higher than that of the solder. The alkali metal hydroxide may be sodium, potassium or lithium, hydroxide. The solder may be a lead-tin eutectic, a tin-lead-cadmium eutectic, a 50% lead, 32% tin, 18% cadmium alloy, a 50/50 lead-tin-alloy, indium, an indium-tincadmium eutectic or a cadmium-tin-leadbismuth alloy. The cover layer may be prepared by reacting zinc oxide or metallic zinc with sodium hydroxide to form sodium zincate with excess sodium hydroxide and adding water 80 grams sodium hydroxide, 3 grams zinc oxide and 17 grams water are heated to produce a cover layer solution containing water, sodium hydroxide and sodium zincate. The ends of a pair of aluminium wires are twisted together and inserted into such a cover layer where the sodium hydroxide removes the aluminium oxide film from the wires and a zinc film is plated thereon. The wires are then passed into the solder below to form a soldered joint. Several immersions into the butt are made. Copper, nickel, or steel parts may similarly be soldered to aluminium or aluminium alloy parts. The water in the cover layer may be replaced by organic solvents, e.g. primary polyhydric alcohols such as glycols, diols or triols and organic materials having hydroxy groups including organic, e.g. citric acid are said to be useful to some extent. The preferred solvents are ethylene glycol; 1,3-propandiol; 1,4- butanediol; 2,2-bis-(hydroxy methyl) 1 butanol and pentaerythritol or mixtures thereof. 9 grams sodium hydroxide and 1 gram zinc oxide are heated to produce the reaction and 90 grams of ethylene glycol are added to form the cover layer solution. The parts to be solderedmay be first dipped in a preparatory bath containing 5% sodium zincate and sufficient sodium hydroxide to clean the parts and the bath may be made from 80 grams water, 16 grams sodium hydroxide and 4 grams zinc oxide. The joint may finally be painted or plastic coated.

Filed: 1957-11-08
Abstract: The invention comprises mixed chromium-containing complexes which unite, through a chromium atom, any non-sulphonated o,o1-di-hydroxymonoazo or o-hydroxy-o1-carboxymonoazo dye with a dye of formula <FORM:0887179/IV (c)/1> where B is an aryl nucleus with Y o to the azo link and Y is OH or COOH.  The dyes may be made in conventional fashion by chroming appropriate mixtures of dyes, or by treating appropriate 1,1 chromium complexes with the requisite metal-free dye.  Dyes of the above formula may be made by diazotising an appropriate amine and coupling with a 3-hydroxythionaphthene or a 2-carboxy derivative thereof, the carboxy group being eliminated during coupling. Indicated as substituents for A are halogen, alkyl and alkoxy radicals and for B are chlorine, bromine, methyl, nitro and acylamino radicals.  Indicated diazo components for the thionaphthene dyes are sulphonated o-amino-phenol and -naphthol, sulphonated anthranilic acid and sulphonated o-naphthylamine carboxylic acid.  Indicated coupling components for the dyes which are not of the above formula are acylacetyl arylamines, phenylmethyl - pyrazolone, b  - naphthol, hydroxy - indazoles, 8-hydroxyquinoline, 2,4-dihydroxyquinoline and 1,7-acylaminonaphthol.  Diazo components indicated for these dyes are substituted o-aminophenols or anthranilic acid.  The dyes colour wool from a neutral or weak acetic acid bath and also other nitrogenous fibres such as poly-amides and -urethanes.  Numerous examples are provided of the preparation of the dyes and their use in colouring processes, green, blue, grey and brown shades being obtained.  Amongst substituents present in the thio-naphthene dyes are nitro, chloro, sulphonamido, methyl and ethoxy groups and in the other dyes are nitro, sulphanimido and chloro groups.

Abstract: 922,417. Digital electric-calculating apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 14, 1959 [Oct. 17, 1958], No. 34841/59. Class 106 (1). Information in binary code can be transferred from a row of a matrix to a buffer register and then to at least two rows of the matrix by coincidence of signals. Also, the information in at least two rows of the matrix can be transferred simultaneously to the buffer register whereby addition can be effected by Boolean principles. Binary adder, Fig. 5. The circles 1-6 indicate cocking gates which are cocked by inputs on the right hand inputs and fired by pulses on lower inputs to deliver pulses of current ¢i, where i is the current required to reverse the magnetic rings making up the matrix memory shown. The other circles indicate pulse sources which deliver pulses of the indicated magnitude at the indicated instants in an 8-instant cycle. At time t 1  binary numbers x, y are entered into rows a, b by a known method. At time t 2  source 16 pulses row a to transfer x to the row k of cocking gates. At time t 3  source 7 fires those cocking gates which have been cooked. Simultaneously, sources 10, 11, 13, 15 supply pulses of magnitude ¢i, whereby the number x is transferred to rows c, d, f, h. At time t 4  source 17 transfers y to the cocking gates and at t 5  y is transferred to rows c, e, g, h. Therefore rows d, f now contain x, rows e, g contain y, and rows c, h contain (x, y). At time t 6  the information in rows c, d, e is transferred to the cocking gates k, but because the read-out wires of row c are threaded through the rings twice in a forward direction, and those of rows d and e are threaded once in the reverse direction the signal in each denomination is s the binary sum of x and y. At time t 7  s is trans. ferred to row a. At time t 8  the information in rows f, g, h is simultaneously transferred to the cocking gates, the signal corresponding to the binary carry c. A new cycle then begins and at t 1  the carry c is transferred to row b with shift to the left. The expressions s and c are then added in the same manner as x and y, the process repeating until row b is empty so that a recycle pulse is no longer applied to wire 24. In a modification (Fig. 6, not shown), three numbers may be added, one of these being the carry from a previous addition.

In an arrangement for recording video information, frame and line synchronizing pulses are generated in pick-up head 16 by marks recorded on a magnetizable layer 15 on a rotating member 14 which is rotated at a speed in synchronism with the frame frequency. The rotating member 14 which is directly coupled to rotating recording head 4 is driven by motor 5 which may be a mains synchronous motor or part of a servo speed control arrangement synchronized to the mains frequency. The speed of tape 1 is similarly controlled by motor 7 or the tape drive shaft 9 may be coupled through suitable gearing to motor 5. Synchronizing pulses from pick-up head 16 control a free running camera 18 which supplies video and synch. signals for recording in oblique tracks on the tape 1. The synch. pulses may also be recorded by head 24 on a separate track on the tape and, where the speed control is exercised by a servo system, may be applied at terminal 20 to the system as an actual speed reference signal. One revolution of the rotating member 14 is effected in a period which is a multiple of the frame period and where the multiple is odd faulty interlacing is prevented by recording twice the number of synch. marks required during one revolution of the member and following the pick-up head 16 with a " divide by two " circuit. The method of recording the marks on the rotating member is also described.
