Title: Method of recovering copper and other metals from solutions
IPC: C22B15/00
Filed: 1944-12-18
Abstract: Cuprous chloride is precipitated from solutions containing cupric salts by adding metallic copper in the presence of chlorine as dissolved chloride.  The chlorine as dissolved chloride should not be less than two gram atoms for each gram atom of copper as cupric salt. Where the remaining solution contains cobalt this may be recovered by oxidising it and treating with alkate to precipitate cupric, ferric and manganic contents.  The solution remaining is treated with soluble alkali and then with chlorine to attain a pH value below 3.5 and to precipitate the cobalt.  Sodium carbonate and chlorine may be added together in the last mentioned step.  Specifications 260,294, 285,662 and 329,225, [all in Class 1 (iii)], are referred to.ALSO:A method of treating solutions containing cupric salts for the recovery of copper comprises adding metallic copper in the presence of chlorine as dissolved chloride whereby cuprous chloride is precipitated.

Filed: 1937-09-20
Abstract: 484,273. Variable speed gearing. HEWITT, B. Sept. 20, 1937. No. 25412. [Class 80 (ii)] A variable-speed transmission device operating automatically by centrifugal action comprises a ring D which encircles an eccentric B or crank-pin secured to a driving shaft A and which coacts with a ring E coupled to a driven drum H by means of springs or resilient material L. Friction between the ring D and the eccentric B is reduced by an antifriction bearing K. As the shaft A rotates, ring D is carried round, while rotating on its own axis, until its centrifugal force causes the ring E to take up an eccentric position and drive results, slipping taking place until a sufficiently high speed is attained. To obtain a balanced arrangement, the mechanism may be duplicated, the two eccentrics being at 180‹ to each other.

Title: Process for the production of coloured photographic pictures
IPC: G03C7/30
Filed: 1935-09-13
Abstract: 464,398. Colour photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Sept. 13, 1935, No. 25468. [Class 98 (ii)] In photographic material having several silver-halide emulsion layers arranged on one or both sides of a support, one or more colour - component pictures are formed by colour development and another or other colour-component pictures are formed by the silver anti-diazotate method. Colour developers specified are diethyl-p-phenylenediamine, p-phenylenediamine; o-toluylenediamine, amino-p-phenylenediamine, chlor-pphenylenediamine, mono -ethyl-p-phenylenediamine, dimethyl-p-phenylenediamine, dibromamino phenol, and dichloraminophenol. Colourforming components having substantive properties in respect of the binding agent of the layer, such as are described in Specification 458,400, are particularly suitable. A threelayer film comprises a non-colour sensitized layer-containing terephthaloyl-bis-acetanilide or benzoyl-acetanilide, an orthochromatic layer containing diphenyl - 4 - 41 - di(carboylamino - phenyl-3-carbethoxy-5-pyrazolone), and a red sensitized layer containing di-(2 - 8-dioxy-3- naphthoic acid)-benzidide. Colour development with dimethylaniline produces a yellow picture in the first layer, a red picture in the second, and a blue picture in the third. The latent image may be developed with dimethylamine-aniline, and the silver picture converted to a silver salt, which is converted into a silver anti-diazotate by treatment with diphenyl di-anti-diazotate. In a weakly acid bath the liberated diazonium compound couples with the unconverted portion of the colourforming component. The film may also be first developed with an ordinary developer, fixed, bleached, re-developed with dimethylamino-aniline, rebleached, and caused to react with an anti-diazotate. Alternatively, the silver produced by the ordinary developer is dissolved, a second exposure is given, and the film re-developed with dimethylaminoaniline. The silver produced is bleached and caused to react with an anti-diazotate. In a modification a film comprising a non-colour sensitized layer containing salicyclic acid benzidide, an ortho chromatically sensitized layer containing 1-(diphenyl)-3-methyl-5-pyrazolone, and a red-sensitized layer containing 1 : 2-oxynaphthoic acid benzidide is developed with dimethylaminoaniline and fixed, the silver in the first layer bleached and transformed into silver diphenyl-di-anti-diazotate and caused to couple with the salicylic acid benzidide by treatment with a weakly acid solution. Specification 387,197 also is referred to.

[Also in Division G2] In an interferometer for making measurements of displacements along two orthogonal axes X, Y utilizing a single light source 11, the latter is mounted on a base (10, see Fig. 2 not shown) and produces a polarized beam, a beam splitter BS1 affords orthogonal beams one of which is polarized in a second polarization, reflectors 5, 6 are movable relative to the base along respective orthogonal axes, reference beams, one for each axis, are produced by means mounted on the base, a fringe measuring means responds to a beam of the same polarization as the polarized light source beam and a further fringe measuring means responds to a beam of the second polarization. In the embodiment of Fig. 3, all apparatus, excepting corner reflectors 5, 6, is mounted on the base, and the beam from laser 11 is initially polarized at an angle arbitrarily designated 0 degrees. One reflected beam from splitter BS1 passes through a splitter BS2 (which acts as a fixed mirror for the Y axis giving a beam Y F ) to a circularly-polarizing #/ 4  plate 21; the beam at X M  from reflexions in reflector 5 and mirror M1 is polarized at 90 degrees. In the path between splitter BS1 and reflector 6 there are included a circularly-polarizing #/ 4  plate 24, a splitter BS3 and a #/ 4  birefringent plate 26. The output beams issuing from splitter BS1 are as follows: X F : " fixed " beam for X axis at 90 degrees polarization. X M  : " moving " beam for X axis at 90 degrees polarization. Y F : " fixed " beam for Y axis at 0 degrees polarization. Y M : " moving " beam for Y axis at 0 degrees polarization. Beams X F  and X M  interfere to give "X" fringes and beams Y F , Y M , "Y" fringes; the fringes are interpreted by photo-multipliers P 1  . . . P 4 , analyzers 12 and 13 being incorporated. The direction of relative movement of reflectors 5, 6 is sensed by including a #/4 retardation plate (31, Fig. 2, not shown) in part of the beam between splitters BS1, B53.

Abstract: 760,122. Anodizing copper. GENERAL ELECTRIC CO. Sept. 21, 1953 [Sept. 20, 1952]. No. 26021/53. Class 41. To form an adherent film of black oxide on copper or copper-surfaced wire or strip suitable for the reception of a resinous insulating coating, the wire is passed through an electrolytic cell in which it forms the anode and which contains an electrolyte capable of producing anodic oxidation and the cell is subjected during the passage of any portion of the wire to at least one complete voltage pulse in which the voltage rises from below a value at which the anodeelectrolyte potential is 0.2 volt so that oxidation is initiated, to a higher value at which oxidation is augmented. Preferably the applied cell voltage in each pulse rises from 0.4 to 2.0, the last high voltage part of the pulse serving to improve the quality of the oxide formed while the anode and cathode are short-circuited between pulses. As shown, copper wire 7 is fed over rollers through an aqueous 13-40 per cent by weight solution of caustic soda or potash at 80-105‹ C. and is connected as the anode in a D.C. circuit including the electrolyte container 14 as cathode. The applied voltage is pulsed as shown in Fig. 1 by an interrupter 23 operated by a power-driven cam 24 which simultaneously closes switch 22 to short circuit anode and cathode, the resistor 18 being pre-set so as to result in the desired pulse shape. An automatic control responsive to changes in operating variables, such as the electrolyte temperature, may be employed to make small adjustments of resistor 18.
