Title: Consumable electrode arc furnace construction and operation
IPC: C22B9/18
Filed: 1956-08-24
Abstract: 806,157. Automatic control systems for arc furnaces. MALLORY-SHARON METALS CORPORATION, [formerly MALLORYSHARON TITANIUM CORPORATION]. Aug. 24, 1956 [slug. 31, 1955], No. 26001/56. Class 38 (4). [Also in Group XI] In an arc furnace having a consumable titaalum.containing electrode which is raised or lowered by automatic control means to maintain a constant arc voltage, the control means are so arranged that difficulties due to ionization of the arc gap are overcome. The electrode 5 is situated in a water-jacketed furnace 1, 2, 3 and arranged to be raised or lowered by motor and reel mechanism 6 . . . 9. A D.C. voltage is applied via sensing device 15 to terminals 11, 13 such that an arc can be struck and subsequently maintained by the control means, between the electrode and the crucible 1. Normal control means 18 operates to raise the electrode when the gap voltage drops due to a decrease in gap size, and to lower the electrode when the gap voltage rises due to excessive gap. The furnace chamber may be operated either under pressure or vacuum, but when under vacuum and the titanium contains certain alloying materials, ionization of their vapours may occur in the arc gap. This reduces the arc voltage and the normal control means responds by raising the electrode although the gap size was previously correct. A tendency to deposit material on the furnace wall occurs and the electrode is then continually raised in an effort to increase the gap voltage. To overcome the difficulty a voltage-sensitive relay 27 is provided to switch the control means on and off in a predetermined manner. If the normal controlled gap voltage is 36 volts then, with switch 28 open, the arc is struck and the electrode automatically raised until said gap voltage is obtained, at which time switch 28 is closed and control means 18 is disconnected by relay 27. The electrode remains fixed, but its lower end burns away increasing the gap voltage until a predetermined upper limit, say 43 volts, is reached: relay 27 is deenergized and the normal control means operates to lower the electrode. At a predetermined lower limit (above the selected gap voltage), say 38 volts, relay 27 is energized, the control means disconnected and the electrode stops, continuing to burn away again at the lower end. The electrode thus moves up the furnace in intermittent steps and ionization in the gap produces no spurious control effect.

Title: Improvements in salvage devices for submarines and the like
IPC: B63G8/41
Filed: 1930-09-01
Abstract: 357,744. Buoy-and-cable devices for sunken ships. CAVALLARI, L., 20, Vicolo Ospedale, Ancona, Italy. Sept. 1, 1930, No. 26091. [Class 68 (i).] A buoy-and-cable device for salving submarines &c. comprises a vertically arranged chamber from which a buoy is released by pneumatically-operated catches, unwinding from drums within it first a light cable, and then a heavy cable for lifting the ship. Fig. 1 shows a chamber 1 containing a buoy 5 secured by dogs 6, and springs 8 as shown. When the ship is sinking, compressed air is admitted to the chamber 1 by the pipe 9 ; the pistons 7 are thus pushed back, the buoy 5 is released and rises, drawing with it a light cable on a drum 3 and eventually a heavier cable on the drum 2. The air may be admitted automatically by a spring-loaded valve which opens when the submarine attains a specified depth, the water pressure then acting on a piston which lifts the valve. In setting-up the device, the free end of the light cable is passed through a pair of rollers 17, 18, Fig. 4, on the end of the heavy cable 2, and is wound up on the drum 3, Fig. 1. When the light cable is completely unwound from the drum, a ball on its end engages with the rollers 17, 18, and the light and heavy cables are thus connected.

Title: Workpiece handling or loading mechanism
IPC: B23F23/04
Filed: 1967-06-07
Abstract: 1,216,309. Transferring workpieces; gear shaving machines. PRECISION GEAR MACHINES & TOOLS Ltd. 7 June, 1968 [7 June, 1967], No. 26303/67. Headings B3B and B3K. A workpiece transfer mechanism suitable e.g. for transferring a gear cluster to a position between centres in a gear shaving machine, comprises a loading arm 4 with workpiece gripping jaws 7, 8 the arm being reciprocable by means of a fluid pressure operated piston and cylinder device 6, 2 to present workpieces 51 to a turret 40 which is indexable to carry the workpiece to a position 43 in which it may be received by the centres and machined. Finished workpieces are carried round by the turret on successive indexing movements and presented to the jaws of the loading arm which, on retraction, carries the finished workpiece back to a conveyer on surface 1. The loading arm 4 is an extension of the piston 6 and the latter is provided with a groove 70, 22, 23 which co-operates on forward or reverse movement, with a detent 21 to turn the arm 4 together with the jaws 7, 8 and workpiece 51 through 90 degrees thus turning the workpiece from the vertical position to a horizontal position or vice versa as it is transferred to or from the turret 40. Limit switches (Figs. 1, 3, not shown) control the extent of movement of the arm 4. Jaws 7, 8 open automatically against spring pressure at the ends of the retraction and forward strokes respectively by the action of pins 14, 15 and 52, 53 abutting fixed surfaces. Indexing of the turret is effected by an hydraulic indexing mechanism 41 which transmits indexing drive movement to a turret end plate 82 through springs 61. This if the workgear does not come into mesh properly with the gear shaving cutter the index mechanism completes its indexing movement but the turret fails to complete its indexing movement the lost motion being taken up by the springs 61. Suitably arranged switches 62, 63 detect this condition and control a partial reverse movement of the index mechanism together with a jogging action of the gear shaver before indexing is again attempted in the forward direction to achieve correct meshing.  The turret comprises a hub sleeve 81 with end plates 48, 49 in which are formed two sets of workpiece seatings 50, 80; in order to bring a different set of seatings 50 or 80 into use the turret can be slid on shaft 73 against the pressure of spring 84, turned through the requisite angle, e.g. 30 degrees and re-engaged in new angular relation with the drive pins 83 by which drive is transmitted from the turret end plate 82.

Abstract: 1379261 Making shaped precision metal articles; forging; casting processes R G BROOKS 16 Oct 1972 [26 Oct 1971 6 June 1972] 49646/71 and 26307/72 Headings B3A B3H and B3F [Also in Division C7] A precision metal article is made by spraying an atomized stream of molten metal or metal alloy on to a surface and working the deposited metal or metal alloy using a die. The surface may be flat or formed in a lower die 19 which is filled with metal or metal alloy and then moved under an upper die 28 for forging whilst still hot or after cooling. The forging dies are housed in a chamber 25 filled with inert or reducing gas, e.g. nitrogen. The metal or metal alloy may be carbon steel, alloy steel, aluminium, aluminium alloy, brass or phosphor bronze, or a mixture thereof. The mixture may be applied simultaneously or sucessively to produce layers. Metallic and/or non-metallic powders, fibres, filaments or whiskers may be incorporated in the metal deposited by spraying.  The molten metal is supplied from a tundish 11 and atomized by gas jets 17 from an annular chamber 15 and cooled by further gas jets. The gas may be nitrogen, argon or compressed air. The degree of porosity of the article produced can be selected by changing the temperature of the molten metal so that the coalescing of the atomized particles varies. Masking plates can be used for the dies which may be coated with a releasing agent. In an example for producing a non-porous aluminium precision article the aluminium is heated to between 100 and 200 C. above its melting point and poured through a nozzle for atomization by gas at a pressure greater than 30 lb./in.<SP>2</SP> at room temperature to produce particles of between 100 and 200 microns size. The die is heated to between 100 and 200 C. to prevent drastic cooling of the particles. The precision metal article'may be a gear wheel, a connection rod, a filter or a shock absorber. The die or dies may be made of nickelchromium-molybdenum steel, chromium-molybdenum-vandadium steel, nickel based alloys or metallic carbides.

Title: Copolymerisation of conjugated dienes with vinyl aromatic compounds
IPC: C08F2/00
Filed: 1971-04-19
Abstract: 1341640 Copolymers of conjugated dienes and vinyl aromatic compounds MICHELIN & CIE (COMPAGNIE GENERALE DES ETABS MICHELIN) 19 April 1971 [9 April 1970] 26679/71 Heading C3P  A copolymer of a conjugated diene and an aromatic vinyl compound is obtained by polymerization in a hydrocarbon solvent to which has been added as catalyst an organolithium compound and a solution of a complex of an alkali metal other than lithium with a ketone in which the keto group is joined to two aromatic groups. The solution of the complex must be moderately polar in order to stabilize the complex but should not be too polar since this favours 1,2-polymerization of the diene. The solvent for the complex is preferably one containing an ether, thioether or tertiary amine group unless the ketone itself contains such a group, when a non-polar solvent may be used. The relative degree of incorporation of the two monomers at any stage in the process may be controlled by selection of an appropriate lithiumalkali metal ratio; if the correct ratio is chosen a homogeneous random polymer may be obtained. The examples describe the polymerization of styrene or vinyl toluene with butadiene or isoprene in the presence of lithium butyl and the following complex solutions: benzophenone-potassium in triethylamine, N,N-dimethylaniline, diphenyl ether or anisole; benzophenone-sodium, -rubidium or -caesium in anisole; and Michler's ketone-potassium in benzene. The effect on the polymerization of the various solvents, and also of tetrahydrofuran, in the absence of the complex is also described. Many other suitable ketones are mentioned including diaryl ketones, anthrone-9, 1,9- benzanthrone-10, xanthone and thioxanthone and their derivatives, and N-organoacridones.

Title: Improvements relating to automatic pre-payment meters
IPC: G07F15/06
Filed: 1926-07-31
Abstract: 278,753. Lulofs, W., and Hanson, A., F. E. July 31, 1925, [Convention date]. Mechanism for prepaying rent of meter; indicators. - An automatic prepayment meter for electricity and other commodities, having an initial or rental fee collecting mechanism is provided with a device which, after the supply of the commodity has been cut off, is so set by the operating mechanism, that is independent of the load, that the supply can only be restored when all the rental fees accumulated have been paid. The prepayment spindle 5, Fig. 1, is moved anticlockwise by the supply meter and the independent operating mechanism through a driving pinion 1 and toothed wheel 2, the movement of the wheel 2 being transmitted to the spindle through a spring 6. When an arm 4 on the spindle 5 comes against a stop 11, the locking lever 7 is freed and releases a toothed switch disc 9 to cut off the supply. The wheel 2 is still driven round by the mechanism independent of the load, so that further coins equivalent to the rental fee due must be inserted before the disc 9 is brought back to pooition. The wheel 2 may gear with a toothed wheel carrying an indicating disc or roller which moves past an arrow or window. The number disc has negative numbers to indicate sums overdue and positive numbers to show prepaid sums. In a modification, Fig. 5, the prepayment spindle 5 carries a toothed segment 16 driven by a toothed segment 17 on a wheel 18 rotated by the driving pinion 19. A locking disc 20 holds the spindle 5 when the supply is cut off, until by inserting the coins due, and rotating the knob segment 17 is brought into engagement with the segment 16. If a certain maximum amount of rental fee due is exceeded, the consumer is prevented from restoring the supply owing to a pawl 23 engaging a notch 22 in a disc 21 which is mounted on the spindle of the wheel 18.

Abstract: 1,211,313. Turbines; axial flow compressors. WESTINGHOUSE ELECTRIC CORP. May 27, 1969 [June 24, 1968], No.26746/69. Headings F1C and F1T. A multi-stage axial flow gas turbine or compressor having an inner casing 43, Fig.4, divided into upper and lower halves 43a, 43b and mounted within an outer casing similarly divided into halves 36a, 36b (36a not shown) includes roller support means to permit rotation of the inner casing within the outer casing during assembly or disassembly. In the Fig. 4 arrangement, the inner casing 43 is normally supported within the outer casing by engagement of axially spaced annular flanges 48, (47), Fig. 3 (not shown), on the inner casing with the inner surface 63 of the outer casing. However should it be required to inspect the stator blades (not shown) carried by the lower half 43b of the inner casing without removing the machine rotor (not shown), the upper half (36a) of the outer casing is removed and rollers 56 are inserted through openings 51 in the lower outer casing half 36b to bear on flanges (47), 48 of the inner casing 43 and thus lift the latter off surface 63. The inner casing can then be rotated on the rollers 56, e.g. by chain hoists 64A, 64B, until the normally lower casing half 43b is uppermost. The latter can then be removed. Each roller 56 is mounted on bearings (58), Fig.5 (not shown), carried by a block (55) supported by a cup shaped plate 53 attached by bolts (62) to the casing half 36b. The block (55) and its roller 56 can be moved radially of the machine by a jack screw 61. The opening 51 for each roller 56 is normally blanked-off by a cover plate. In a modification, Fig. 6, as well as being divided into upper and lower halves 70a, (70b), the inner casing is further divided in planes normal to the machine axis into rings 74, 75, 76, 77 which sealingly abut but are not joined to each other so as to be individually removable. Each ring 74 to 77 is normally supported within the outer casing by diametrically opposite keys (84), Fig. 7 (not shown), clamped between the joining flanges (72) of the ring halves and engaging the corresponding joining flanges 85 of the outer casing halves (73a), 73b. To permit inspection of the stator blades carried by the lower half of any of the rings 74 to 77 the upper half of the outer casing is removed and a jack bolt 87, 88, 89 or 90 screwed into each of the supporting keys (84) of the appropriate ring so as to lift the ring away from the outer casing half 73b. Lengths of roller chain 91 are then inserted between annular flanges 79, 82 on the ring and the facing surfaces of the outer casing half 73b. The appropriate jack bolts 87 &c. are unscrewed to lower the ring on to the roller chain 91, the keys (84) are removed, and then the ring is rotated on the rollers using chain hoists (92, 93), as before, to bring the normally lower ring half uppermost for removal.
