Title: Improvements in or relating to the colouration of materials
IPC: D06P3/82
Filed: 1934-10-02
Abstract: A dye preparation, which may be in the form of a dry powder, comprises a water-insoluble dye having affinity for cellulose acetate, an acid dye and a dispersing agent, the mixture being substantially free from water and from substances insoluble in a mixture of a major proportion of ethyl alcohol and a minor proportion of water, and a stain for colouring textile fabrics is obtained by dissolving such a preparation in a liquid containing, as a major constituent, an organic solvent for the water-insoluble dye.  Such stains are suitable for colouring, as by spraying or brushing, textile materials which must not be immersed in a dyebath, such as fabric uppers of shoes, handbags with metal fittings and fabric covers of electric conductors.  They may be used, for example, for colouring cellulose esters or ethers, regenerated cellulose, natural silk, or mixtures thereof in shades fast to light.  Specified water-insoluble dyes are aminoanthraquinones, various azo dyes, 2-nitro-4-chlor-4<1>-ethoxydiphenylamine and dyes sold under the trade name "S.R.A." or the Registered Trade Marks "Celliton" and "Dispersol."  Specified acid dyes are Erio flavine 3G, Orange I, Orange IV, Brilliant sulphon red B, Soluble blue 487, Coomassie violet R, Alizarin light blue FF, Direct black 3131, Rose bengale, Fast acid blue RH, Erioglaucine A, Croceine scarlet 3BDS and Patent blue 9879.  Specified dispersing agents are turkey red oil and sulphuric acid esters of oleyl and other higher aliphatic alcohols. Specified organic solvents are methyl, ethyl and propyl alcohols and esters or ethers of di- or polyhydric alcohols.  Wetting agents, such as alkylnaphthalenesulphonic acids may also be present in the stains. Penetration of the stains into cellulose ester or ether materials may be facilitated by the incorporation of swelling agents for such materials, specified swelling agents being formal-glycerol, ethyl lactate, diacetone alcohol, glycol esters or ethers, aromatic sulphonamides, and phenols, e.g. hydroquinone.  In an example, a black stain comprises 1 : 4-di-(ethanolamino)-5-oxyanthraquinone, 1 : 4-aminooxyanthraquinone, benzene-azo-1-naphthalene-4-azo-4<1>-phenol, Direct black 3131, Erioglaucine A, ethyl lactate, turkey red oil, "Gardinol" Registered Trade Mark CA, a mixture of isomeric xylenemonomethylsulphonamides, methylated spirit and water. Stains producing differential dyeings on the fibres of a mixed material may also be prepared.  A table is given specifying various mixtures of water-insoluble and acid dyes suitable for the production of stains of particular shades.

Title: Improvements in or relating to a method and apparatus for storing information

Filed: 1968-06-21
Abstract: 1281991 Cathode-ray storage display tubes UNITED KINGDOM ATOMIC ENERGY AUTHORITY 13 June 1969 [21 June 1968 5 June 1969] 29845/68 and 28605/69 Heading H1D [Also in Divisions C4 and G4] A method of storing information comprises irradiating a phosphor (e.g. single or polycrystalline KI : T1, and 1 mm. thick) with radiation of energy content sufficient to damage the phosphor so as to affect its luminescent properties, irradiating selected regions with radiation of higher energy content so as to anneal at least partially any damage at said regions, the distribution of annealed and damaged regions being representative of the information to be stored. Radiation damage may be by electrons or protons for example, reducing subsequent luminescence by more than <SP>1</SP>/ 100 , and annealing may be by electrons from the same source as the damaging electrons by heating to above a few hundred  C., e.g. 400 to 500 C. In binary digital data storage, a 20 kV., 6À4 W., 2 Ám. diameter electron beam damages in <SP>1</SP>/ 5  Ás. Annealing times may be reduced by <SP>1</SP>/ 100  by annealing only half the defects. With cathodo- and photoluminescent phosphors, readout may be by an even lower intensity electron beam from the same gun or from U.V. light respectively, e.g. light from source (IT) on to c.r.t. screen (12) (Fig. 2, not shown). The electron beam may be scanned and modulated between the damage and anneal levels. Annealing may be achieved without raising above the m.p. but partial melting produces a faster anneal in which case a thin high melting point metal foil is on the exposed phosphor surface to retain molten phosphor. Annealing by increased defect mobility as well as a purely thermal mechanism is considered. A photocathode, preferably in another tube, e.g. photomultiplier tube (5) with CsSbO photocathode (6) (Fig. 1, not shown) may be combined with the c.r.t. with a 6 mm. square, 1 mm. thick phosphor layer for storing 10<SP>7</SP> bits of digital information. The three electron beams currents are 1, 200 and 5000  and 15 kV. producing a 1 Ám. penetration depth. Access and writing may be sequential or random and analogue storage is referred to the luminescent intensity at a given dose being a linear function of current, and at given current, an exponentially increasing function of dose. The impurity concentration is especially important in the latter case, a polycrystalline compact made by pressed die technique being preferable.

Abstract: Alkali metal polyphosphate complexes of  alpha -6-deoxy-5-hydroxytetracycline are prepared which have the formula                    (C22H24N2O8)z . (MePO3)x . (HPO3 )y in which Me is sodium or potassium, z = 1 to 5, x = 1 to 5, y = 1 to 5, x + y </= 6 and z </= y. The compounds are obtained by reacting metaphosphoric acid in an organic medium which is inert to the reaction with 1 to 5 mol of  alpha -6-deoxy-5-hydroxytetracycline. The remaining free acid groups of the metaphosphoric acid are then neutralised with a methanolic or ethanolic solution of sodium hydroxide or potassium hydroxide in the stoichiometric quantity. The complex formed in this process is then precipitated by addition of a non-solvent which is inert to the reaction. Preferred compounds are the ethanol/water solvate of the complex of the formula                   C22H24N2O8 . NaPO3 . (HPO3)5 and                     C22H24N2O8 . (NaPO3)2 . (HPO3)4. The said compounds have an antibiotic activity, and they are very highly tolerable.
