Abstract: 1,148,789. Pattern operated thread guides heald frames. GOLD-ZAG INTERNATIONAL S.a.r.l. 14 Sept., 1966 [14 Sept., 1965], No. 41099/66. Headings D1C and D1E. Thread guides of a knitting machine or heald frames 11 of a loom are moved by a continuously rotating eccentric 20 by way of pattern operated toggle links 24 which remain straight when the guide or frame is to be moved and are broken by the pattern mechanism, so that the eccentric has no effect, when the guide or frame is to remain unmoved. The invention is described in relation to a loom to shed a frame from bottom to top sheet level and one eccentric serves all the frames although two eccentrics may be provided when it is desired to retain a frame at the top sheet level. Alternatively a solenoid operated catch 33 may retain a frame at top level. The degree of "break" of the toggle links may be controlled to shed the frames to three levels and the toggle joints may be replaced by flexible or telescopic members. In the toggle linkage, a stop 28 prevents complete straightening of the links and a solenoid operated slide 30 is retracted when it is desired' that a toggle should break. Various pattern mechanisms to control the breaking of the toggles are described.

Title: Coating articles by electrophoresis
IPC: C25D13/22
Filed: 1964-10-09
Abstract: In electrophoretically coating with organic film-forming material articles connected as one electrode moving through a coating bath, the articles pass first through a zone in which coating is effected at a chosen current density and then through a second zone with a higher or increasing coating current density. This may be achieved by employing a coating tank that forms the other electrode and decreases in depth and width from the entry to the exit end or by providing an insulating barrier e.g. of glass, ceramic, polythene or polypropylene, to vary the current path resistance e.g. a cup-shaped wall adjacent one end of the tank. Alternatively the article path through the tank which is non-conductive may be separated by a series of insulating walls of differing lengths and opening intervals from the counter electrodes or by continuous porous walls which do not allow passage of the coating material, the chambers so formed containing electrodes and being fed with liquids of controllable conductivity and hence allowing control of the current passing to the article. The coating materials may be anodically depositable paints comprising polymers with free carboxyl groups and ammonia or a water soluble amine as dispersing agent or cathodically depositable paints comprising polymers with amine or quaternary ammonium groups and a water soluble carboxylic acid or buffered phosphoric acid as dispersing agent.  Pigments, dyes, drying oils, other resins and organic solvents may also be included in the paints.  The dispersing agent may pass through the porous walls between the article path and the counter electrodes to remove excess from the bath.  Supplementary counter electrodes may be disposed within inaccessible parts of the articles and voltages different from that applied to the main counter electrodes may be employed.

Title: Improvements in corrosion-resisting decorative chromium electrolytic deposits
IPC: C25D3/12
Filed: 1965-10-04
Abstract: A micro-cracked Cr coating (i.e. one having cracks spaced from one another by 10-50 microns) is produced on an object by electrolytically depositing an intermediate Ni layer in such a manner that during subsequent electro-plating of the Cr the Ni and Cr simultaneously micro-crack. The Ni plating is carried out in an aqueous acid Ni bath at a maximum temperature of 35 DEG C. and a current density between 1 and 15 A/dm2, the bath comprising on the one hand nickel chloride, sulphamate or fluoborate and on the other hand one or more of ammonium acetate and of the following acids and their nickel salts:- acetic, gluconic, tartaric, formic, malic, lactic, citric and succinic acids.  Prior to electro-plating with the cracking Ni, the object may be degreased and be plated with Cu, brass or dull, levelling, semi-bright or bright Ni.  The cracking Ni electrolyte may contain a brightening agent which is a sulphonate, sulphonamide or sulphonimide of an aromatic compound (e.g. saccharine), butyne 1-4 diol, or an amino derivative of a heterocyclic compound (e.g. 2-amino-thiazole) or a Co salt. During the plating, of the cracking Ni, impurities may be removed from the electrolyte by known methods, e.g. electrolytically.  When cracking- Ni is to be plated on bright Ni, the bright Ni may be depassivated electrolytically in a bath containing NaOH, Na2CO3 and NaCN. Conventional Cr plating baths may be used comprising as catalysts the sulphuric, hydrofluoric and fluosilicic ions. The use of Cr baths containing Se and of Ni baths containing particles which are insoluble in the Ni is said to be not incompatible with the use of the cracking deposits specified above.

Abstract: 1429517 Electro-photographic element XEROX CORP 7 Sept 1973 42183/73 Heading G2C An electro-photographic element is formed by applying a shrinkable film which is optionally conductive, to a base having a resilient surface, shrinking the film into compressive contact with the  surface, applying a layer of conductive material if the film is not conductive, and applying a layer of photo-conductive material. The base may be of metal or plastics reinforced with glass fibre and is provided with a resilient surface by coating with neoprene or butyl rubber, other materials also being specified. The film in compressive contact may be polyethylene terephthalate optionally containing carbon particles. The conductive material is preferably aluminium which has been deposited in vacuo and superficially oxidized to give an insulating barrier layer. Other conductive materials are specified and the barrier layer may be of plastics or inorganic material. The photoconductive layer is exemplified by selenium optionally alloyed with arsenic but other photoconductors are specified. A protective coating of an insulating resin may be provided on the photoconductive layer. In the embodiments a cylinder 5 of aluminium-copper alloy is given a rubber coating 6 which is optionally cured by heating and ground. A shrinkable sleeve of polyethylene terephthalate 7 is placed around the coated cylinder and shrunk into place by heating. An aluminium coating 8 is formed by vacuum deposition and exposed to air to form a superficial oxide layer then a selenium layer 9 is deposited in vacuo. An alternative embodiment Fig. 4 (not shown) has a compressive conductive film (23) in place of films 7 and 8. The resilient surface may be cured before, during or after application of the compressive film. The base to be given the compressive film may be planar and coated on one or both sides with a resilient substance, alternatively an endless belt may be used. The film may be formed by heat shrinking a tube around the base or tacking the film along the edge or underside of the base prior shrinking it. The film may be shrunk into place by solvent vapour or tension.
