Patent GB-445501-A (GB)
Title: Process for the preparation of basic copper sulphates and ammonium sulphates
IPC: C01C1/244
Filed: 1934-12-21
Abstract: <PICT:0445501/III/1> Basic copper sulphates are obtained by treating copper or a copper bearing material, in the presence of air or oxygen and ammonia, with a sulphur-oxygen compound of reducing character such as sulphur dioxide and separating the basic sulphates so formed. Alternatively, the treatment in the presence of air or oxygen may be effected by means of a solution of a sulpho-ammonium compound or compounds of reducing character such as ammonium sulphite, bisulphite, thiosulphate or hydrosulphite. The copper may be in the metallic form or in the form of oxides or alloys.  The liquors from the reaction containing ammonium compounds may be returned to the process, if necessary after the addition of sulphur dioxide and ammonia.  The ammonium sulphate accumulating in the liquors may be recovered continuously or intermittently, for example by precipitating the metal sulphur compounds by means of sulphur dioxide.  The basic sulphates formed may be treated with sulphuric acid to neutralize the ammonia and filtered.  The basic sulphates separated by filtration may be dissolved in sulphuric acid to obtain normal copper sulphate.  The sludges or liquors may be treated with a base such as lime, the evolved ammonia being returned to the process, while the mixture of basic copper sulphates and calcium sulphate being drained and dried to give an anticryptogamic product to which inert substances or adhesives such as dextrine may be added.  The liquors containing ammonium sulphate and copper compounds may also be treated with milk of lime to yield ammonia which is returned to the process as ammonium sulphite and an anticryptogamic powder. Copper in the form or scrap or hollowshot is placed in a tower 1 provided with a false bottom 2.  Air or oxygen is introduced through a pipe 3 and a solution of ammonium sulphite containing free ammonia through a pipe 7.  Excess of air carrying some ammonia flows away through a pipe 8 and is treated with water and sulphur dioxide in a scrubber 9, the resulting aqueous ammonium bisulphite being returned to the reaction through a pipe 10.  The sludges collecting at the bottom of the tower are removed through an opening 5 and settled in a tank 11, the clear liquid being returned to the tower through a pipe 12 after its ammonium sulphite content has been restored.  Ammonium sulphate may be recovered from the liquid as already described.ALSO:The sludges or liquors containing basic copper sulphates, obtained by acting on copper or a copper bearing material with ammonia and sulphur dioxide, or ammonium sulphite, bisulphite, p  thiosulphate or hydrosulphite, in the presence of air or oxygen, are treated with a base such as lime, the resulting mixture of basic copper sulphates and calcium sulphate being drained and dried to give an anticryptogamic product to which inert substances or adhesives such as dextrine may be added.

Abstract: 1,043,847. Rotary drum mixers. FIBERFIL IAG. Sept. 18, 1963 [Sept. 18, 1962], No. 36734/63 Heading B1C. A continuous discharge blender or tumbler comprises a rotary drum 12 of small axial length in relation to its diameter and having a diametrical partition 15. Material is fed into the inclined hollow shaft 11 and passes through a slot 24 into the first chamber 16 where it is tumbled by flights 20 until it builds up to the level of an aperture 26 in the partition 15, through which it passes into the second chamber 17. Here it is again tumbled by flights 20, a proportion falling on the shoot 30 which delivers it into the hollow shaft for discharge or transfer to the next drum of a series on the shaft, see also Fig. 1 (not shown). The first chamber 16 may also have a shoot 34; this plays no part in the mixing operation, but if the direction of rotation is reversed the broad outer ends of the shoots 30, 34 act as scoops to discharge the apparatus rapidly. As shown, the drums are hexagonal and have inspection and access covers 22. Residence time in chamber 16 is controlled by the number, size and desposition of the aperatures 26 and in chamber 17 by the arrangement of the flights and shoot.

Title: An improved dyeing process
IPC: C09B3/78
Filed: 1961-10-13
Abstract: Cellulose materials are dyed by applying an onium compound of a vat dyestuff containing at most 8 fused carbocyclic rings, at least one stage of the process being performed in the presence of a reducing agent.  The dyeing is fixed by splitting-off the onium group.  The onium groups may be ammonium, sulphonium or isothiouronium groups bound to the nucleus through a methylene bridge.  They may be obtained by quaternating amino groups or by converting mercapto-methyl compounds by rearrangement into ternary sulphonium salts by known methods or by treating mono- or bischloromethyl compounds of vattable dyestuffs with (a) tertiary amines such as pyridine, picoline, isoquinoline, quinoline, trimethylamine, triethylamine, benzyl-dimethylamine, diethylaminoethyl alcohol or dimethyl-cyclohexylamine, or (b) an alkali metal compound of a mercaptan such as methyl mercaptan, n-butyl mercaptan, cyclohexyl mercaptan, benzyl mercaptan, thiophenol or para-thiocresol and converting the sulphide formed into a ternary sulphonium salt by means of dimethyl sulphate, or methyl paratoluene sulphonate, or (c) thiourea, N-methylthiourea, N:N-dimethylthiourea or tri- or tetramethylthiourea.  Suitable vat dyestuffs are anthraquinones either containing an unmodified 9:10-dioxoanthracene ring or containing fused carbocyclic or heterocyclic rings or from the perylene tetracarboxylic acid, naphthalene tetracarboxylic acid or indigoid vat dye series.  They may contain usual substituents such as halogen atoms, alkyl, alkoxy, acylamino, sulphone or sulphonamide groups.  The dyestuffs may also contain a water-solubilizing group capable of being split off, e.g. a sulphate group.  The dyes may be applied to regenerated cellulose, linen or especially cotton by padding or from a dyebath.  Fixation may be achieved by maintaining the impregnated material in the vat state in the presence of an acid-binding agent and a reducing agent at 10 DEG -40 DEG C. for 2-48 hours, particularly by the pad-roll process.  Dyeing from a dyebath may be achieved below 50 DEG C. in which case the dyebath may contain neutral electrolyte such as sodium chloride or sulphate.  Specified reducing agents are sodium sulphide, hydrosulphide, hydrosulphite and thiourea dioxide and the specified acid-binding agents are sodium hydroxide and carbonate.  The reducing agent and alkali may be applied together with the dye, during or after the dyeing process. Printing may be effected with a thickened printing paste.  A reoxidative aftertreatment may be included as well as soaping and washing prior to drying.  Examples are given in which are used dyes of the following formulae: <FORM:0925768/IV(a)/1> Specifications 613,980, 613,982, 613,983 and 850,159 are referred to.
