Abstract: 311,433. British Celanese, Ltd., and Ellis, G. H. Dec. 13, 1927. Azo dyes applicable for dyeing or otherwise colouring cellulose esters or ethers are obtained by coupling diazotized aminoxanthenes with coupling components such as phenol, dimethylaniline, m-toluidine, p-xylidine, cresidines, anisi. dines, m-phenylenediamine, nitro-m-phenylenediamine, m-aminophenol, monoacetyl-m-aminophenol, dimethyl-m-aminophenol, 1- or 2-naphthylamine, or 1-amino-2-methoxynaphthalene. Diazo and polyazo dyestuffs are obtainable from the monoazo dyestuffs by coupling with diazo components or by diazotizing amino groups therein and coupling with components. The aminoxanthenes may carry substituent groups, e.g. carboxy, alkyl, halogen, substituted amino, hydroxy, alkoxy, carboxyester, or mercapto groups. In examples of the dyeing process the dyestuffs are derived from diazotized 2-methyl-3- amino - 6-dimethylamino-9-o-ethylcarboxyphenylxanthyl chloride. (Rhodamine 3G extra). Dye preparations.-The above azo dyes when relatively insoluble in water are applied to the goods as aqueous dispersions which may be produced by colloidal grinding, by dissolving in a solvent and mixing with water containing, if desired, protective colloids, or by the use of dispersing agents as described in Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, or 273,820.

IPC: B21C1/12
Filed: 1958-10-22
Abstract: 863,053. Wire drawing. LUCAS (INDUSTRIES) Ltd., J. Oct. 21, 1959 [Oct. 22, 1958], No. 33726/58. Class 83 (4). In a draw-bench of the kind in which a wire passes through a plurality of dies and is drawn through each die by being wound on to a drum, the tension of the wire is controlled by varying the speed of each drum in response to changes in its position produced by changes in the wire tension. Each winding drum 7 is mounted in a frame 9 which can swing on trunnions 10. The wire 5 enters the drum in the plane of the axis of the trunnions 10 and in a direction at right angles to both that axis and the rotational axis of the drum, and leaves at a point offset from the axis of the trunnions. The resultant moment is opposed by a spring 12 and variations in the position of the drum cause a servo mechanism to produce corresponding changes of speed in a motor 8 driving the drum. The servo mechanism comprises a cylinder 13, containing a spring 16 and a piston 14, connected to the motor speed controlling arm 15. Both ends of the cylinder are connected to the source of fluid pressure for the motor 8, the end which contains the spring 16 is connected through the restriction 17 and is also connected by a further pipe to a relief valve 18. When the frame 9 moves, the valve 18 opens and a pressure difference is created across the piston 14 which causes the piston to move against the spring 16 and thereby reduce the speed of the motor 8.

Abstract: 959,289. Extruding. BURGESS-NORTON MFTG. CO. Oct. 7, 1960, No. 34533/60. Heading B3P. An extrusion press has a punch 14 and a workpiece ejector 34 aligned with an extrusion die 1, the downward retraction of the cushion and ejector being delayed until the extrusion stroke of the punch has begun. The punch 14 has an enlarged head 22 and is surrounded by a sleeve 15; both are mounted in a block 17 secured to a reciprocable punch holder 19. Die 1 has a tapered outer surface 2 fitting within a block 4 mounted on one or more supports 8 from a base 9. A fixed pin 25 projects into the die bore and is surrounded by the ejector sleeve 34 actuated through rods 36 and cushion block 41, Fig. 4, by a compressed air motor 50, Fig. 9 (not shown). In a cold extrusion process, a slug 42, Fig. 4, of sintered metal coated with a colloidal graphite lubricant or steel coated with zinc stearate or molybdenum disulphide, is placed in the die 1 where it rests on the pin 25 and is first extruded backwardly by punch 14, Fig. 5 (not shown). Meanwhile, rods 20 extending upwardly from the cushion 41 have been depressed by the holder 19 to prevent actuation of the ejector. When the backwardly flowing metal engages the end of sleeve 15, the slug is then extruded forwardly over pin 25 to form the workpiece 42, Fig. 1. Finally, punch 14 is withdrawn, Fig. 7 (not shown), and ejector sleeve 34 is moved upwardly by the air motor to eject the workpiece. Fig. 8 (not shown). The punch holder 19 is withdrawn sufficiently to provide a clearance between it and the rods 20 at the end of ejection. This clearance causes the delay in retraction of the ejector until the next extrusion stroke has begun. In a further embodiment, Fig. 8 (not shown), two parallel dies are mounted on the base for the simultaneous extrusion of two separate slugs.

Abstract: 1464032 Rolling metal T SENDZIMIR 7 Aug 1974 34764/74 Heading B3M An elongate workpiece is reduced in thickness by feeding it into a reducing zone and moving a beam backed roll in the lengthwise direction of the workpiece along the zone, the roll taking a series of reducing passes each against successive crests of an anvil, the crests being substantially stationary relative to the workpiece. In the embodiment of Fig. 3, the work roll 2 is supported by backing rolls 4<SP>1</SP> on a rocker 8 which rolls over a fixed beam 7. The opposing anvil may be a crested body movable slightly in the direction of workpiece advance during the working stroke of roll 2, being returned by springs during the return stroke of the roll. As shown however the anvil is composed of a row of rolls 3 supported on back-up rolls 4 rotatable on eccentric shafts 5 by individual drives to raise or lower rolls 3. Some or all of rolls 3 may be driven, e.g. at surface speeds in excess of those at which the workpiece moves in the vicinity of the respective rolls. In Fig. 6, work rolls 2 are mounted in a cage 18 on a backing roll 17 which rotates continuously in one direction. The radius of the rolls 3 may decrease in the direction of strip advance. The rolled strip passes upwardly through a fluidized bed 21 of cooling granules, non-oxidizing gas being blown in at 23, 23<SP>1</SP>. The heated granules escape from the top of the bed into chambers 24, 26 where they are cooled as they descend by cold water pipes 27, 27<SP>1</SP>. In the embodiment of Fig. 7, the strip is reduced firstly by the action of work rolls 2 opposed by anvil rolls 3, and then by the action of rolls 2 opposed by segments 3a, see also Fig. 8, each of which is curved at its end facing block 31 and is mounted on the block by spring 32, so that the segments rock as the work roll passes, and are restored by the springs. The strip then passes a block 36 presenting a smooth face so that any irregularities left from the proceeding stages are ironed out, the block being free to move slightly in the direction of strip advance as the work roll passes, and being returned by springs (Fig. 10, not shown). The rolled strip is fed through a cooling bath 42 of a circulating eutectic mixture of lead and bismuth. An inert gas is admitted at 47 to a hood 46. The strip is then cold-rolled in a four or more stand tandem mill 49, and coiled at 50.
