Title: Electrolytic refining of metal
IPC: C25C7/08
Filed: 1972-09-09
Abstract: 1417705 Electrolytic metal refining BRITISH COPPER REFINERS Ltd 7 Dec 1973 [9 Sept 1972] 11060/72 Heading C7B In the refining of metals e.g. Cu, Zu or Ni, by a process in which direct current is passed through a bi-polar series of unrefined electrodes whereby impure metal is anodically dissolved from and pure metal cathodically deposited on opposite faces of each electrode, the electrodes are removed, e.g. as a whole group, before total dissolution of all their impure metal and are passed, e.g. individually, to apparatus which mechanically separates the pure and impure metal portions thereof. Separation may involve splitting, e.g. with a blade, and/or distortion e.g. using the apparatus of Specification 1417259. Percussion, vibration or passage between rollers may also be used. Separation may be facilitated by (1) leaving the top of each electrode out of the electrolyte whereby a sharp boundary is produced at the edge of metal deposition, (2) placing a removable conductive wedge along one edge of the cathodic surface during deposition and/ or (3) coating the cathodic surfaces with a release agent. The process may be automated, with the separated metal portions conveyed away separately with automatic and/or selective rejection of unsatisfactory electrodes.

IPC: A41D19/04
Filed: 1919-05-03
Abstract: 149,394. Evans, F. R. May 3, 1919. Feeding webs; collapsible spindles and rollers. -A machine for automatically cutting blanks for gauntlet cuffs and the like from one or more plies of web material comprises a rotary cylinder over which the work passes and during the rotation of which the work is cut by one or more knives adapted to be traversed across the cylinder under the constraint of pattern plates carried thereby. The work is clamped to the cylinder during the cutting operation by gripper fingers automatically controlled and when released therefrom the cut blanks are disengaged from the cylinder. Mechanism is provided for guiding and tensioning the work in its passage to the cylinder and arrangements are provided for varying the dimensions and contour of the blank cut. Fig. 4 shows a rotary cylinder 13 provided with a pattern plate 54 and co-operating cutting mechanism adapted at each revolution of the cylinder to sever the work transversely according to the pattern slots 63, 62, 61, 64, 65. Two vertically reciprocable knives 146 may be employed, the one traversing the slots 63, 61, 65, and the other in the slots 62, 61, 64. The work is clamped to the cylinder for the cutting operation by gripper fingers 79, 80, 114, 119, inter-connected and operated from springs controlled automatically from a timing trip gear 68, so that the fingers 79, 80 are moved transversely over the work to engage the same in the vicinity of the slots 63, 61 prior to the operation of the cutters therein, the fingers 114, 119 likewise operating subsequently to clamp the work at the other edge as the cutters approach the slots 64, 65. The grippers are released by cam gear operating during the rotation of the cylinder to reset the grippers in position to receive a further length of work. Resilient devices are provided to depress the grippers into engagement with the work as they move into gripping position, a needle point on the cylinder also serving to retain the work in position. When released from the grippers subsequent to the cutting operation the cut blank is deflected from the cylinder by a spring device and allowed to fall on to a pile beneath the cylinder. The cylinder is carried by a sleeve rotated slowly through gearing from a power driven pulley adapted to be coupled to the sleeve through a treadle-controlled clutch. To vary the length of blank cut the cylinder 13 is provided with resilient peripheral plates adapted to be adjusted by screws to vary the circumferential length of the cylinder. The work is guided to the cutting mechanism from its supporting rolls by a frame 224, and disks 222, Fig. 25, and suitable tension is imparted by weight-controlled plates 214, 216, adapted to bear on each face of the work as it passes to the cylinder 13.

Title: Electro-photographic imaging process
IPC: B41M5/025
Filed: 1963-03-22
Abstract: 1,041,404. Electrophotographic processes. MINNESOTA MINING & MANUFACTURING CO. March 22, 1963 [March 22, 1962], No. 11559/63. Heading G2H. A reproduction process comprises exposing a photoconductive, electrolytically developable sheet to produce a differential conductivity pattern thereon, electrolytically forming a pattern of a vapourizable image-forming material on the exposed surface corresponding to the differential conductivity pattern (i.e. forming the pattern by electrolytic deposition of the material, by electrolytic removal or destruction of the material, by electrolytically depositing in selected areas a substance capable of masking the material or by electrolytic reaction with the material so that a new material is formed which is less vapourizable), positioning the sheet into contact with a receptor sheet and heating so that vapourizable material is transferred and a visible image corresponding to the conductivity pattern is formed on the receptor sheet. After image-wise exposure of the photoconductive sheet to visible light, X-rays or electron or proton beams, a vaporizable reducing agent such as an alkyl pyridinium bromide, an alkyl quinolinium or quinaldium iodide or an aromatic amine is selectively deposited and on contact and heating with a receptor sheet containing silver behenate, triphenyl tetrazolium, methylene blue or crystal violet, a visible positive or negative image is produced. Alternatively the exposed photoconductive layer may contain a reducing agent (hydroquinone, catechol) which is selectively electrolytically oxidized before contacting with a receptor sheet above. Instead of electrolytic oxidation, a nickel salt or catechol may be complexed by electrolytic deposition of dithiooxamide and a ferrous salt respectively which immobilises the nickel salt or the catechol. Electrolytic masking is accomplished by selective deposition of a polymer, a resin, a chelate compound or a Werner chromium complex onto the vapourizable material. Other possibilities are electrolytic deposition of a vapourizable dye which is directly transferred to a receptor sheet, or electrolytic deposition of dimethyl glyoxime or catechol which on transfer complexes with a nickel soap or a ferrous salt contained in the receptor sheet.
