Title: Rolling mills
IPC: B21B1/18
Filed: 1954-10-15
Abstract: 758,424. Rolling. MORGAN CONSTRUCTION CO. Oct. 15, 1954 [Oct. 23, 1953], No. 29726/54. Class 83 (4). A rolling mill comprises three groups I, III, V, Fig. 1, of horizontal roll stands with a vertical roll stand II-V or IV-V between the groups, at least one of the vertical stands IV-V being selectively driven from either a high-power motor 31, Fig. 2, through a reduction gear for reducing operations or from a lowpower motor 32 for edging operations. The mill may be readily adapted for rolling rod, strip, angles, &c., of different dimensions. Billets heated in a furnace 11 are fed to the stand some of which may be idle according to the type of work being rolled. After passing a shear S the work reaches further horizontal and vertical stands VI-V, VIII-V and may be led off through a guide 15. Alternatively, the work may be fed through looping guides 13, 16, 19, 20 to further finishing stands XI-XII or if unsuitable for looping may be fed on to reversing tables 14 or 17. Different types of work may alternatively be led off to reels 12 from the finishing stand XII or directly from the stand X or it may be fed from the stand X along a runout table 18 leading to a cooling bed. Figs. 3-7 (not shown) indicate various stages with the mill adapted for rolling round bar and rectangular bar, flat strip and angle sections, Fig. 7 showing the apparatus adapted for two strand. rolling with all the vertical stands idle.

[Class 106 (ii)] The size and profile of a part D<SP>1</SP> of uniform cross-section is gauged by a tool comprising a trough A having the inner surfaces of its sides truly flat and parallel and each engaged by the outer face of a block B or C having a truly flat lower face at right angles to its outer face and an inner face shaped to conform to one of the sides of the part D<SP>1</SP>, the space between the blocks having a uniform cross-section and a longitudinal centre line inclined at a small angle to the outer faces of the blocks, one of which can be detachably connected to the trough. As shown, the size of the root of a turbine blade D is indicated by the position of the block C relative to a scale on a side of the trough, the block B being set in a datum position by a screw E. Chambers on the blocks facilitate the entry of the blade root between them. Errors in the angular position of the longituinal axis of the blade relative to the root may also be determined, and the blocks B, C may be used alone to detect errors in the relative position of the contours on opposite sides of the root. Specification 646,043 is referred to.

In a trawl gear, a cable set for a trawl net comprises a pair of link wires 17 each linking a point 18 on a headline leg 13 to a point 19 on a ground rope 16 aft of each end 20 of the ground rope. During trawling the links are slack but during shooting and hauling the headline legs are advanced, by means described below, relative to the groundline legs 16 to tension the links 17 and also the headline legs 13 to prevent fouling thereof with the groundline legs 16. The means for advancing each headline leg 13 comprises an independent piece 27 attached at one end a haul ring 28 in the headline leg and at the other end to the warp 24 forward of the otter board 23. The headline leg 13 and the groundline leg 12 are joined at a towing point 26 and a Kelly's Eye 30 connects the towing point 26 to a backstrap 25 connected to the otter board 23. When the otter board 23 reaches the gallows and is secured thereto, the hauling tension is then applied to the independent piece 27 whereby the haul ring 28 advances relative to the towing point 26 and the Kelly's Eye then slides on the groundline leg 12. The point 26 has a stop for the Kelly's Eye 30. The link wire 17 is made in two parts 32, 33, Fig. 5, to enable the ground rope to be drawn up to the gunwale. When a ring 35 at the point 18 reaches a sheave mounted on the gallows a messenger wire is passed over a further sheave and connected to a flattened link 38 on the end of the lower part 33 of the link wire. The latter is pulled through a ring 36 on the upper part 32 of the link wire 17.

Abstract: The invention comprises dyestuffs of the formula <FORM:1080385/C4-C5/1> wherein F represents a residue of an organic dyestuff, W is a bridge member, X is a reactive substituent, Y is a reactive substituent and m is 1, 2, 3 or 4.  Preferred reactive substituents are chlorine or bromine or arylsulphonyl, alkylsulphonyl, arylthio and aryloxy groups. Specified organic dyestuff classes are water-soluble metal-free or metal-containing mono-or polyazo dyes, metal-free or metal-containing aza-porphin dyes, anthraquinone, oxazine, dioxazine, triphenylmethane, nitro, azomethine, benzanthrone and dibenzanthrone dyes and polycyclic condensation compounds of anthraquinone, benzanthrone and dibenzanthrone compounds.  A preferred bridge member is the -NH- group, which may be substituted and may be linked directly to an aromatic nucleus of the dyestuff molecule or via an alkylene, aralkylene or arylene group.  The dyes may be obtained either by reacting a dyestuff which contains an amino or amide group which carries a reactive hydrogen atom with a compound of the formula <FORM:1080385/C4-C5/2> or by reacting diazo or coupling components which contain amino or amide groups which have at least one reactive hydrogen atom with a compound of the above formula.  Numerous examples are given for the production of mono- and disazo metal-free and metal-containing dyes, anthraquinone dyes, phthalocyanine dyes and nitro dyes.  The dyestuffs are useful for dyeing textile materials containing nitrogen or hydroxyl groups, especially textiles derived from natural or regenerated cellulose, wool, silk, synthetic polyamide or polyurethane fibres (see Division D1).  1 - Amino - 4 - (41 - aminophenylamino) - anthraquinone - 2,5,8-trisulphonic acid is obtained by reacting phenylene-diamine with 1 - amino - 4 - bromo - anthraquinone - 2,5,8-trisulphonic acid sodium salt in the presence of cuprous chloride.ALSO:Textile materials containing nitrogen or hydroxyl groups especially those derived from natural or regenerated cellulose, wool, silk, synthetic polyamide and polyurethane fibres are dyed with reactive dyestuffs of the formula: <FORM:1080385/D1-D2/1> wherein F represents a residue of an organic dyestuff; W is a fridge member, X is a reactive substituent, Y is a reactive substituent and m is 1, 2, 3 or 4 (see Division C4). Dyeings or prints derived from dyes containing groups which form metal complexes may be treated with metal-yielding agents.
