Title: Improvements in or relating to apparatus for extruding metal
IPC: B21C23/30
Filed: 1933-10-09
Abstract: 429,918. Squirting. PIRELLI-GENERAL CABLE WORKS, Ltd., and HORLEY, R. E., 343, Euston Road, London. Oct. 9, 1933, Nos. 27825/33 and 3607/34. [Class 83 (iv) A method of extrusion, employing apparatus wherein the metal is fed to the die by inner and outer relatively rotated concentric members of which one is a screw impeller and the other has keyways or recesses, comprises holding the metal in the keyways substantially stationary relatively thereto to restrain rotation of the metal in the screw impeller by friction. Square recesses 4, Figs. 1 and 2, may alternate with square projections 5 to produce a " draughtboard " pattern, or continuous or intermittent longitudinal grooves or helical grooves of the same hand as those on the impeller 2 may be provided in the surface of the chamber 1. The method may, for example, be carried out by so regulating the temperature and rate of extrusion, in accordance with the dimensions of the apparatus, that the metal is solidified along 75 per cent of the length of the grooves, numerical examples being given. A number of working chambers with their screw-impellers 2, Fig. 5, may be disposed about the mandrel and die 9, 7. The die assembly 10, 12 is that described in Specification 418,078, and the concentricity of the die is preferably adjustable. The screw impeller is preferably of a different metal from that of its complementary member, the screw impeller being for example of a hightensile steel such as that sold under the Registered Trade Mark " Vibrac " while the chamber is of cast iron or has a cast iron lining, with a surrounding steel sleeve. The clearance between the screw and the chamber may vary along the length, and the screw may be conical and may have a curved generating line, the chamber being similarly formed. The state of the metal in the press chamber is controlled by heating means 15, such as gas, oil, electric resistance, or electric induction heaters, and it is cooled by cooling jackets 16 or by spraying on hot water, steam oil, or air. Coolant may be circulated within the impeller by channels 17 and oil may be circulated between a cable and the member 9. The degree of heating and cooling may be thermostatically controlled. Alternatively, the current taken by the driving motor may be taken as an indication of the plasticity of the metal, the cooling means being reduced automatically or otherwise as the load increases or the cooling being maintained constant, and the motor-speed varied. A slow drive is provided so that the press may continue to run slowly while repairs or adjustments are made, the current to the motor being reduced for this purpose, or a change-speed gear, a variable-speed gear, or a fluid-clutch drive, being included in the driving mechanism. Instead of the slow drive the lead supply may be cut off and the screw allowed partially to empty. The material held by the recesses 4 may differ from that being extruded and may be, for example, retained from a previous extrusion operation.

Abstract: 945,259. Lathes. HOLO-KROME SCREW CORPORATION. Aug. 11, 1960 [Aug. 11, 1959], No. 27897/60. Headings B3B and B3T. A work-holding and transferring device for an elongated article, such as a socket-head screw, comprises movable fingers 87 for engaging an article which has been moved by feeder means 46 to a pick-up station and for transferring it into alignment with a first work-holder 14, a pusher 100 for moving the workpiece into the holder, and a reciprocating frame 18 and a rotating transfer element 20 for transferring and reversing the article to allow a second pusher 101 to push it into another work-holder 16. The work-holders consist of collet chucks 14, 16 operated simultaneously by cam mechanism 32 through a lever 38. Conventional ejector mechanisms are contained in each chuck. Workpieces are fed along adjustable guide rails 43, 44 which support their heads. Periodically, the gate 46 is moved into alignment with the rails by a cam 64 which oscillates a yoke 60 to reciprocate a plunger 53 connected by a pin 51 to a plunger 47 carrying the gate 46. The plungers can be held in a retracted position, if desired, by a locking plunger 70. The gate is formed with grooves to receive the head and shank of a workpiece. A further cam-driven mechanism 86 oscillates a lever 84 to oscillate levers 83, 82 and a gear-sector 79 thus reciprocating a rack 78 to cause reciprocating and oscillating movement of a rod 97 carrying the spring fingers 87 which can pick up a workpiece from the gate 46. Thus, in operation, the gate separates a workpiece from the rails 43, 44, advances it into alignment with the fingers 87 which are moved to grip it. The gate is withdrawn and a cam 67 (not shown) permits oscillation of the rod 97 as it advances so that the workpiece is moved into alignment with the collet 14. Ejection plungers 100, 101 are then advanced by a cam operated lever 109 and yoke 105, the plunger 100 serving to transfer the workpiece from the fingers 87 into the collet 14, and the plunger 101 serving to transfer the workpiece from fingers 132 to the collet 16. The workpieces are then operated on by tools 28, 29 on rock-shafts 115, 116. The fingers 132 are carried on twin oscillating arms 20, 22 operated by a rack 126 from a cam-controlled lever 136 to swing a workpiece end-for-end from the collet 14 to the collet 16 and from the collet 16 to a position where the finished workpiece can be removed by a third ejection plunger 160 into a receiver. To accommodate varying lengths of workpieces the arms 20, 22 are carried on the frame 18 which is reciprocated axially of the collets by a cam-operated mechanism 140, a bell-crank 141 and an adjustable link 144. Reference has been directed by the Comptroller to Specification 853,650.

Title: A process for dyeing nylon
IPC: D06P3/24
Filed: 1947-10-20
Abstract: Nylon textile materials are dyed by forming a chromium complex of a dyestuff on the fibre by treating the nylon with an acid solution of a dyestuff capable of being after-chromed, then with an acid solution of a dichromate and finally with a reducing agent.  Suitable reducing agents are formaldehyde, sodium hydrosulphite, sodium bisulphite and sodium thiosulphate.  A small amount of fish glue may be added when using sodium thiosulphate to prevent the precipitation of sulphur. The quantity of dichromate employed may be between 0.5 per cent to 1 per cent by weight of the polyamide material.  Formic acid may be added to the acid dye solution, and the dyeing process may be retarded by the addition of ammonium acetate and ammonia before the solution is acidified. Suitable dyes mentioned and used in the examples are of the Solochrome series.  Specification 543,198 is referred to.
