Title: Improvements relating to Heat-Treating Workpieces Undergoing Multi-Stage Forming Operations.
Inventor: SPIELMANN ERICH ROLAND
IPC: B21D22/20
Filed: 1966-06-28
Abstract: 1,171,779. Making pressure vessels; stamping. BRITISH OXYGEN CO. Ltd. 27 June, 1967 [28 June, 1966], No. 28893/66. Headings B3A and B3Q. [Also in Division C7] A method of heat-treating a workpiece 17 undergoing a multi-stage forming operation comprises introducing the workpiece into a heating zone until it reaches a desired temperature, withdrawing it from the zone, immersing at least the heated part in cooling liquid, and moving the workpiece towards the next stage with the heated part remaining immersed in the liquid so as to cool the heated part below the temperature at which significant oxidation occurs. The method may be carried out at a station 1 in a multi-station drawing press for making carbon dioxide bulbs from strip, the partly-formed blank passing through the heat-treatment station before going to a station 2 where the open end of the blank is drawn down to form a neck. At station 1, a piston 12 carrying the blank by means of spring clips (not shown) is lowered, and then a head 14 carrying the piston is lowered to locate the neck portion of the capsule 17 in a highfrequency heating coil 8 contained in a chamber 4 filled with water. The coil is de-energized when the capsule reaches about 800‹ C. The head is then raised to immerse at least the heated part of the blank in a liquid curtain or, as shown, in a bath of water 11, after which the head is moved horizontally to station 2 and the piston raised so that the blank follows the path 18, remaining immersed to the edge of the tank. The cooling liquid may extend into and beyond station 2, and more than one neckdrawing and heat-treatment stage may be included.

Abstract: 246,106. Renault, L. Jan. 19, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Supervising central station plant.-Apparatus for permitting a centrally-located person to listen. in to the running of several distant machines, comprises a helmet containing a receiver which may be connected by switching means either individually to any one or simultaneously to all of a number of acoustic or electrical sound transmatting means extending from each machine to be supervised. The invention is described with reference to the supervision by a. pilot of a number of engines on an aircraft. During flight the receiver is connected to all the sound transmission means and the pilot hears a blending of the sounds of all the engines. If a defect occurs in one of them, an abnormal element presents itself in this complex sound and the pilot may identify the faulty engine by individually switching his receiver on to the different engines. The arrangement is also applicable to supervising the working of turbines and other machines at an electricsupply station.

Abstract: 786,685. Coating ferrous sheets with metal by dipping. KRUGER, C. M., WARDEN, C. P., DRIVER, W., HOLDEN, W. E., GAFF, H. D., WAAL, D. M. DE, and ARMCO INTERNATIONAL CORPORATION. Oct. 20, 1955 [Feb. 7, 1955], No. 30052/55. Class 82(2) A ferrous strip is coated by immersion in a molten metal and then passes through interdigitated wipers whilst submerged in a bath of liquid material immiscible with the coating metal and hot enough to keep the metal coating molten. By this means a controlled thickness of coating is produced. A continuous process is disclosed (Fig. 1) wherein strip is fed from rolls 1, 1a alternately, the ends of the strips being welded to provide an endless strip, and the strip then passes via the looper 5 to a furnace 7 where it is oxidized and degreased (solvent or chemical degreasing may be practised), then to a reducing furnace 8 which can also be used for heat treatment in conjunction with a cooling section 9. The strip passes into the coating bath 11 through the downtake 10, in a.reducing atmosphere. The strip enters the bath at a temperature approximating to the bath and due to the cleaning is instantly wetted by the coating metal, no flux being needed. The strip passes round the roller 12 (Fig. 2) and out of the bath through the oil or other liquid 15 maintained hot enough to keep the coating molten. Wipers 19, 28 bear against the strip causing deflection as shown and maintain a narrow line contact with the strip, the degree of deflection being set so as to flatten the strip transversely and produce the required contact pressure, by adjustment of the bracket 21 carrying wipers 28. The wipers are preferably made of a metal such as steel which wets tin, and should have a nose of about 1/16 inch radius when new. Best results accrue from setting the blades at an angle of 10-15 degrees from the normal to the strip as shown. The strip now passes through wipers 29, cooler 30 and degreasing unit 31 to a cold rolling step in rolls 32; tension rolls 33, 34 and a lubricating unit 35 also being provided. The original oil 15 if suitable, may be left on and the degreasing and lubricating steps dispensed with. The lubricant used for cold rolling may be removed at 36 and a different lubricant applied at 37 to suit the buyer where the coated strip is also buffed. The strip is sheared at 39. Specification 453,803 is referred to.
