Title: Improvements relating to reactive metal-containing disazo dyestuffs and their use
IPC: C09B62/032
Filed: 1961-03-17
Abstract: The invention comprises reactive dyes of formula <FORM:0973890/C4-C5/1> where R1 is a coupling component residue, R2 is a coupling component residue with -OMe o to the azo bond, X is the residue of a heterocyclic imide halide bound to R1 or R2 by way of an amide group, which imide halide also has at least one reactive halogen atom, Me is a metal of atomic number 24 to 29 which can also be complexly bound with other complex formers, n is 1 or 2 and m 1-4. The dyes may be made by reacting metal-containing disazo dyes of the above formula where X is an acylatable amino group with a heterocyclic poly-C-imide halide or by metallizing appropriate metal-free dyes. Indicated as imide halides are e.g. 2,4,6 - trichloro - 1,3,5 - triazine, 2 - alkoxy-, alkyl-, phenyl-, amino-, alkylamino-, sulphophenylamino- and guanidino-4,6-dichloro-1,3,5-triazines and 2,4- or 4,6-dibromo-pyrimidines which contain in other positions substituents such as halogen atoms or nitro, acyl, cyano, alkyl or phenyl groups and tetrameric cyanogen bromide. Copper, chromium and cobalt are specified metals and indicated as other complex formers are chromium compounds that contain aromatic o-hydroxycarboxylic acids or only one o,o1-dihydroxy, o-hydroxy-o1-amino- or o - hydroxy - o1 - carboxy - azo dye per metal atom. The disazo metal-free dyes, used as starting material, may be made by conventional methods of diazotization and coupling, the required acylatable amino group either being present in one of the components or formed after coupling from e.g. a nitro or acylamino group, and amino groups may first be acylated with m- or p-nitrobenzoyl chloride and the nitro group of the resulting dye converted to the amino group for acylation with the imide halide. Indicated coupling components are m-toluidine, cresidine, aminohydroquinone diethyl ether, m - phenylenediamine, 1 - naphthylamine, 2 - amino - 5 - naphthol - 7 - sulphonic acid, 2 - amino - 8 - naphthol - 3,6 - disulphonic acid and 1 - (41 - aminophenyl and 31-amino-61-sulphophenyl) - 3 - methyl - 5 - pyrazolones. Preferably only one of R1 and R2 has an acylatable amino group. The dyes colour cellulosic or polyamide materials in blue and black shades. Di- and tri-chloropyrimidyl amino group containing dyes, especially copper dyes, are preferred. Dyeings and prints are fixed by treatment with an acid-binding agent. Examples are provided of the preparation of the dyes and their use in colouring cellulosic fibres. Reference has been directed by the Comptroller to Specification 797,946.

Title: Removal or iron from solution
IPC: C22B3/44
Filed: 1969-03-04
Abstract: Iron is removed from an aqueous solution containing both Fe2+ and particles of MnO 2 by adjusting the pH to between 2 and the pH at which Fe2+, Zn2+ and Cd2+ ions form hydroxides, the Fe2+ being adsorbed by the MnO 2 and oxidized by the MnO 2 to Fe 2 O 3 which is then separated from solution as Fe 2 O 3 .MnO 2 . Preferably the MnO 2 in added after the adjustment of pH. Any iron in solution which is not as Fe2+ may first be reduced to Fe2+ by, for example, ZnS. The MnO 2 has a mesh size (Tyler) preferably between 50 and 300 and the temperature is preferably between 20 C. and the boiling point of the solution. The solution may be that derived from leaching ores also containing zinc, and/or cadmium. The Fe 2 O 3 .- MnO 2 may be subsequently treated with mineral acid (e.g. H 2 SO 4 ) to dissolve the iron, as Fe3+, the MnO 2 being recovered and re-used or the Fe 2 O 3 .MnO 2 may be treated with further Fe2+ solution until all the manganese is in solution at Mn2+.

Title: Apparatus for peeling off the leading edge of a receiving sheet from a transfer image carrier
IPC: G03G15/14
Filed: 1977-09-12
Abstract: An apparatus for peeling off the leading edge of a sheet of paper adhering to a moving transfer image carrier during the process of transferring a powder image onto the sheet. The apparatus includes one stripper member or a plurality such as three stripper members mounted in the vicinity of the transfer image carrier at the side on which the sheet is intended to be detached from the same. The one or several stripper members engage the moving sensitive surface of the image carrier at a balanced extremely low contact pressure and are adapted to be lifted off this surface by a peeled-off sheet of copying material. The strippers are continuously reciprocated in a direction transversely of the transfer image carrier and thereby likewise transversely of the advancing sheet so that the problem of traces that may be engraved into the surface of the transfer image carrier is virtually overcome and the useful life of the image carrier is substantially extended.
