Abstract: 1470801 Making rollers; casting composite articles; rolling mills HITACHI METALS Ltd 7 May 1974 [11 May 1973] 20073/74 Headings B3A B3F and B3M [Also in Division C7] A composite sleeve having an outer diameter greater than 100 cm. and comprising an outer layer of high-alloyed steel having a Shore hardness of 60-75 and a carbon content of 0À4- 0À9% and an inner layer of low-alloyed steel having a Shore hardness of 30-45, is produced by centrifugal casting. The metal forming the inner layer is poured into the mould before complete solidification of the metal forming the outer layer. After removal from the mould the sleeve is subjected to a homogenizing and spherodizing treatment and is hardened in a quenching and tempering furnace prior to being mounted by shrinkage fitting on a shaft to form a back-up roll for a rolling mill. The ratio of the thickness of the sleeve to its outer diameter is 0À1 : 1 to 0À3 : 1 and ratio of the thickness of the outer layer to that of the inner layer is 0À4 : 1 to 1À2 : 1.

Patent GB-852120-A (GB)
Title: New monoazo-dyestuffs derived from cyanuric halides and their manufacture and use
IPC: C09B62/085
Filed: 1957-06-28
Abstract: The invention comprises dyes which contain at least two acid groups imparting solubility in water and are of formula X-D-N=N-A where A is the residue of a keto-methylene compound bound to the azo link in a position vicinal to an enolized or enolizable keto group and X is a 2, 4- dihalogen -1, 3, 5- triazine residue bound through an -NH- bridge to D, a diazocomponent residue, which contains, together with A, at least one bicyclic aromatic nucleus. The dyes may be made by usual processes of diazotization and coupling, or by condensing appropriate triazine halides and monoazo amino-dyes, the latter method being of especial use when A is the residue of a component that requires strong alkali for coupling since such media are apt to react with the halogen atoms of a triazine diazo component.  The products may be dried and may contain buffers such as mono- and dialkalimetal phosphates. Specified acid groups are sulphone, sulphonamide and advantageously sulphonic and carboxylic acid. Cyanuric chloride is the specified triazine.  Representative of specified components corresponding to D are 4, 41-diaminodiphenyl -3- sulphonic acid, 4, 41-diaminostilbene -2, 21- disulphonic acid, 4-(31- aminobenzoylamino) -1- aminobenzene -2-carboxylic acid, 1, 4- diaminobenzene and its 2-carboxylic acid and 2- methoxy -1, 4- diaminobenzene -5- sulphonic acid.  Representative of indicated coupling components are acetoacetic acid and its arylides, 3- methyl -5- pyrazolones, 1- phenyl -3- methyl -5- pyrazolone -41- sulphonic acid, 1-(31- nitrophenyl) -5- pyrazolone-3- carboxylic acid, 1- naphthyl-(11) -3- methyl-5- pyrazolone -41- and 1- naphthyl-(21)-3-methyl-5- pyrazolone -61, 81- disulphonic acids and <FORM:0852120/IV (c)/1> pyrazolone components being preferred.  The dyes are particularly useful for dyeing cellulosic fibres especially in a cold aqueous alkaline bath (see e.g. Specification 797,946). Examples are provided of the preparation of the dyes and their use in dyeing cellulosic fibres in yellow shades.  Specification 849,115 is disclaimed.
