Title: Production of aromatic diamines
IPC: C07C209/18
Filed: 1966-04-12
Abstract: Mixtures of p-phenylene diamine derivatives are obtained by heating a primary aromatic amine with a p-aminophenol substituted on the nitrogen atom by a saturated aliphatic or cycloaliphatic radical of 1-20 carbon atoms, the reaction being effected in the presence of a catalyst comprising iron chloride or a mixture of iodine and powdered iron containing 0.75-6 parts by weight of iodine per part of iron. The reaction may be carried out at 175-250 DEG  C., optionally with the addition of an azeotropic agent, e.g. xylene.  In a typical example, aniline and N-(1,3-dimethylbutyl)-p-aminophenol yield a mixture containing N,N1-di - (1,3 - dimethylbutyl) - p - phenylene diamine, N - phenyl - N1 - (1,3 - dimethylbutyl)-p-phenylene diamine and N,N1-diphenyl-p-phenylene diamine.  Other examples describe the reaction of N-(1,3-dimethylbutyl)-p-aminophenol with o- and p-toluidines and mixtures of toluidines, and the reaction of N-isopropyl-p-aminophenol, N-cyclohexyl-p-aminophenol and N-sec.-octyl-p-aminophenol with a mixture of toluidines.  Other specified aromatic amines which may be treated are p-tert.-butyl-, p-amyl-, p-hexyl-, p-octyl-, p-decyl- and p-dodecylaniline, a - and b -naphthylamine and xenyl amine.  The products are useful as rubber antioxidants.

Filed: 1952-06-25
Abstract: 749,501. Feeding spools to and from machines. DAVY & UNITED ENGINEERING CO., Ltd. June 24, 1953 [June 25, 1952], No. 16000/52. Class 120 (3). [Also in Groups XVI and XXII] An apparatus for transporting and processing coils of material in strip, web or filamentary form carried upon spools comprises stationary input and output banks of one or more arbors for accommodating spools carrying unprocessed and processed material respectively, an uncoiling drum arranged to receive a spool, a movable input arbor on a first transfer carriage for transferring a spool from an arbor of the input bank to the uncoiling drum, a coiling drum for receiving an empty spool, processing apparatus drawing material from the uncoiling drum and delivering it to a spool on the coiling drum, a movable output arbor mounted on a second transfer carriage and arranged to transfer a spool from the coiling drum to an arbor of the output bank, a first reservoir of spools which receives empty spools from the movable input arbor and a second reservoir of spools which delivers spools to the movable output arbor, the spools carrying material only being moved when supported on arbors. As shown, coils of strip material, wound on spools, are loaded on to arbors 48, 49 and 50 by a truck 78 carrying a similar arbor 80 having a stripper plate 81 for sliding coils axially off the arbor. A carriage 68, slidable along rails 69, can be positioned axially in alignment with each arbor 48, 49 and 50, such that the coils thereon may be slid axially on to an arbor 70 by operation of stripper plates such as 89. The carriage 68 supporting a coil on the arbor is brought into axial alignment with an uncoiling drum 43, such that the coil may be slid off the arbor 70 on to the drum 43. The material is then passed through processing means which, as shown, is a rolling machine having rollers 14 driven by a motor 17 and transmission unit 18. The material is then rewound on a reel supported on a coiling drum 21, the initial turns preferably being formed by a wrapping means, not shown. Completed coils are removed from the drum 21 to arbors 56, 57 and 58 by a carriage 73 having an arbor 75 and operated in the same manner as the carriage 68 and arbor 70. Empty reels are removed from the uncoiling drum 43 to the arbor 70 and then positioned opposite a conveyer 65 which carries them away from the rails 69, such reels being then transferred to a conveyer 67 moving in the opposite direction from where they are transferred to the drum 21 as required. The truck 78 may, if desired, transport coils from the arbors 48, 49 and 50 to the drum 43 and similarly from the drum 21 to the arbors 56, 57 and 58, thus dispensing with the carriages 68 and 73. Instead of rolling strip metal the processing may be finishing, dyeing, or printing of textile webs, calendering or printing of paper webs, or processing filamentary material, e.g. wire, textiles, or rope.

Title: Improvements in or relating to devices for the removal of the cut-off unextruded residue from extrusion presses
IPC: B21C35/04
Filed: 1955-06-07
Abstract: 770,734. Extruding; shearing. SCHLOEMANN AKT.-GES. June 7, 1955 [July 8, 1954], No. 16293/55. Class 83 (4). [Also in Group XXXV] An extrusion press, particularly for extruding aluminium, having a ferromagnetic pressing disc 3 disposed in front of the press ram 2, has apparatus for removing from the press the pressing disc 3 with the cut-off extrusion residue 4 adhering thereto, comprising a magnetic device 9 adapted to be moved in a plane normal to the press axis and to be selectively energized and de-energized whereby when the device 9 is on the press axis and adjacent the pressing disc 3 it can be energized to grip the disc and the cut-off residue adhering thereto, and then moved away from the press axis whereupon it is de-energized to release the disc and the residue. The extrusion press comprises a slidable die-holder 7 through which extruded product 4a passes and which carries a die 5 supported by a pressure plate 6. The dieholder 7 is adapted to move towards the container 1 whereby the die 5 is engaged within the bore of the container and is held therein by a wedge 8. After extrusion the die holder 7 together with the die 5, the extrusion residue 4 and the pressing disc 3 adhering thereto due to the extrusion pressure are withdrawn to a position adjacent a cutting knife 11 which severs the residue 4 from the product 4a. A permanent magnetic device 9 suspended by means of a rod 10 from a pivot has meanwhile been positioned adjacent the pressing disc so as to grip the latter together with the workpiece 4 and, after the severing operation, to remove it away from the centre line of the press. The permanent magnetic device 9, Fig. 2, comprises a series of permanent magnets 12a, 12b, 12c having alternate north and south poles adjacent each other. A separate disc 13 of non-magnetic material, such as aluminium, is rotatably mounted on the front of the device 9 and contains iron bodies 15, Fig. 3 (not shown), corresponding to the magnets 12a &c. The disc 13 is rotatable by a handle 14 from one position in which the iron bodies are aligned with the magnets in the device 9 and thus the latter is energized so as to grip the pressing disc, to a second position in which the iron bodies 15 are disposed at positions 15a whereby they short-circuit the magnetic path of the magnets and therefore de-energize the magnetic device. The magnetic device may be energized automatically when it is swung into its position adjacent the disc 3 in the centre line of the press, and de-energized automatically when it is swung out of this position.
