Abstract: 1,121,599. Extruding; billet piercing. HYDRAULIK G.m.b.H. 26 July, 1966 [11 Nov., 1965], No. 33615/66. Headings B3H and B3P] In the manufacture of metal tubes and the like from unpierced billets on an indirect extrusion press, the billet is placed within a container 3, Fig. 3 (not shown), and upset between the indirect extrusion stem 4a and an upsetting member 9, the latter is then exchanged for a hollow closure member 10, Fig. 7, and pierced by an independently operated mandrel 11, and the billet is then extruded into a tube 19, Fig. 8 (not shown), between the mandrel and a die 4<SP>11</SP> carried by the extrusion stem 4a. Two transversely movable stems 4a, 4b, are provided and are stationary whilst the billet is extruded by moving the closure member 10 and container 3 to the right by means of a press plunger 1<SP>1</SP> and thrust member 7. The upsetting die 9 and closure member 10 are mounted on a transverse slide 8 on the front of the press plunger 1<SP>1</SP>. During piercing, the billet metal expands into space (12), Fig. 6 (not shown) and after piercing, a wad 13 is ejected. The mandrel 11 may be held stationary during extrusion or may be locked to the press plunger 1<SP>1</SP> by bolts 16. After extrusion, an enlarged portion 14 of the mandrel shears off the residue discard 18 and shell 18<SP>1</SP>, Fig. 9 (not shown), where they adhere to the dovetail face of the closure member 10. Slide 8 then moves transversely, Fig. 10 (not shown) the residue is removed by a stripper 19, Fig. 11 (not shown), crushed by a press 20 and deposited into a scrap bin 22. The billets 6 are supplied to the extrusion press by a charger 5, Fig. 1 (not shown).

Title: Improvements in machine for making hairpins
IPC: B21G1/00
Filed: 1920-11-29
Abstract: 176,852. Lewis, A. J. Nov. 29, 1920. Pins, dress and like.-In a machine for making hair-pins of the kind shown in Fig. 14, a straight wire is severed and subjected successively to bending to U-form, crimping and upsetting at the ends, and bending of the leas; the wire being moved vertically between the operations so as to engage the contours of three parallel planes of the mandrel 68. The wire is initially led through the reciprocating-gripper 36, Fig. 1, past the holder 55, Fig. 2, and through the shearing device 60 to the mandrel 68. The wire fed is held against the initial contour of the forming mandrel 68, Fig. 8, by a lever 69 and which so held is severed by the shear blades 65, Fig. 1. The die 95, Fig. 8, which is superposed on a transferring device 96 mounted on a vertical slide 93 in the block 89, is then advanced bv the cam 76 to bend the wire to U-shape, after which the vertical slide is lowered by the cam lever 101 to position the wire on the second contour of the mandrel. Crimping-dies 121, Fig. 2, are next advanced by the cams 120, 116 and while the wire is held therein, the bending-die 95 is withdrawn and lifted for the reception of fresh stock, this movement also bringing the groove of the transferring member 96, Fig. 8, opposite the wire already operated on. Simultaneously with this operation, the free ends of the original work piece are upset by the dies 80, Fig. 2, operated through the cam 85 and lever 84, after which the block 89, Fig. 8, is again advanced, bending the second wire to the U-form and closing the transferring member on to the wire in the crimping-dies. The latter are then withdrawn and the slide 93 lowered, whereby the first work-piece is positioned on the lowest contour of the forming mandrel and the second work-piece brought to the second contour. The next advance of the dies 121 crimps the second wire, and closes the original workpiece to the form shown in Fig. 14. The continued operation of the dies 95, 121 in this sequence, releases the finished hair-pins which drop into a waiting receptacle.

Title: Improvements in or relating to electric switches
IPC: H01H21/18
Filed: 1922-12-11
Abstract: 212,620. Crabtree, J. A. Dec. 11, 1922. Switches, quick-action.-In a switch having a pivoted operating member which drives, through lost-motion, a pivoted rocking member provided with quick-acting spring mechanism for both directions of movement, the contact-member which is movable under spring control in relation to both the first-mentioned members is pivotally carried, with intervening insulating material, upon the eccentrically located part of a stump or crank constituting the rocking member. In the construction shown the handle a is fixed on the short spindle d in the casing and the spindle carries a lug e engaging and serving to drive, with lost motion, one arm b<1> of a stirrup rocking member b the arm b<1> being pivoted on the spindle d and the other arm pivoted on a spindle k at the other end of the casing. The stirrup carries insulated brackets i with ears i<1> between which the contact-members c are centrally pivoted so as to have a portion extending on both sides of the pivot for engagement with the contests c<1>, c<2>. The contact members have a free movement, limited by the bracket i, on their pivots and a coiled spring j or helical springs are employed to bias the contact-member in the relative position shown in Fig. 6. In breaking the circuit, the spring is strained but the contact-member is held in the fixed contacts by the friction grip. Subsequently, the contactmember is driven to the off position with the rapid action imparted to the rocking member by the telescopic compression spring g on its pivoted carrying member f, g<2>, assisted by the spring j. The member f, g<2> constitutes a toggle with the arm b and the toggle is so set that, in the movement for closing the circuit rapidly, the toggle passes further past the dead-centre position than in the opening movement, thereby ensuring a greater mechanical advantage for the closing movement. The telescopic compression spring may be replaced by a dead centre tension spring secured at one end to the bottom of the casing and at the other end to the upper part of the arm b<1>, or by a reaction spring arrangement wherein a spring-mounted roller on the casing reacts with a cam formation on the arm b<1>

Title: Improvements relating to lubricating devices
IPC: F16N29/02
Filed: 1946-11-14
Abstract: 618,835. Lubricating. ROTAX, Ltd., BARRINGTON, E. W. J., and ROBINSON, E. E. Nov. 14, 1946, No. 33803. [Class 12 (iii)] A lubricating arrangement wherein a lubricant-soaked pad bears on a rotary or moving part of a mechanism comprises temperature responsive means for reducing the pressure of the pad on the moving part with increase in temperature. As shown in Fig. 1, a lubricantsoaked pad 3 pivotally mounted on a pin 4 is spring-urged against a cam 1 of an interrupter mechanism for a spark ignition system. The free ends of a pair of bimetallic strips 8 mounted on the base 5 between a spacing member 9 embrace the ends of a pin 7 protruding slightly through the pad on each side. With an increase in temperature, the free ends of the bimetallic strips close upon the ends of the pin 7 to brake the oscillatory motion of the pad, thus decreasing the pressure between the pad and the cam. Fig. 3 shows the pad 3 spring urged by a bimetallic helical spring 11 anchored at one end to a bracket 13, the other end being seated in a slot 10 in the pad, so that with an increase in temperature the bimetallic spring exerts less pressure on the pad. In a further construction a bimetallic helical strip is loosely mounted on the pivot pin of the pad and arranged so that with an increase in temperature it contracts thereon and opposes the action of a separate spring. Fig. 8 shows a construction wherein three bimetallic washers 22, normally flat, are arranged on a pivot pin 19 with an increase in temperature they each assume a dished form and exert a braking pressure on the base of the pad 18.

Title: Formation of polygonal images
IPC: G06K15/22
Filed: 1969-07-04
Abstract: 1,269,994. Photo-copying apparatus. R.C.A. CORPORATION. July 4, 1969 [July 5, 1968], No. 33887/69. Heading G2A. In the imaging of a filled in polygon Fig. 4 (not shown) of a predetermined shape on to a photosensitive sheet 10, firstly a relatively narrow outline image (65) is formed by selecting one of a plurality of apertures 41 in a disc 42 and moving a copying head 12 containing the disc 42 round a closed path in accordance with data fed to X and Y stepping motors to expose an outline of the predetermined shape on the sheet 10, and then successive interior images, each formed as border images overlapping at least one other previously formed image, are similarly exposed within the outline image, also in accordance with data fed to the motors, until the whole outline image has been filled in. The head 12 is then ready to be moved, with light source 32 switched off, to another position over the sheet 10 to produce the next solid polygon image. In accordance with controls signals fed thereto, the disc 42 is rotated between the formation of each part-image to change the aperture 41 in the exposing light beam, and hence the size of the exposing light spot, in order to minimize the number of closed path movements of the head 12 necessary to fill in the outline image. In the event of the predetermined polygon shape being a re-entrant polygon Fig. 11 (not shown), the image is made in stages by sub-dividing the re-entrant polygon along the bisector of its reentrant angle, and treating the two portions (98, 99) so formed each as a polygon to be imaged as described above. This prevents over-exposure in the neighbourhood of me re-extrant angle. The image producing means could alternatively be an electron beam in a cathode ray tube or a pen.

Title: Pretreatment of petroleum coke for carbon disulfide manufacture
Filed: 1955-11-29
Abstract: <PICT:0783942/III/1> In the production of carbon disulphide by the interaction of petroleum coke and sulphur vapour, the petroleum coke is pretreated with an oxygen-containing gas at a temperature of 600-1000 DEG  F., preferably 650-850 DEG  F., and for a period of 15 minutes-50 hours.  Not more than 20 per cent, more preferably not more than 10 per cent, of the coke is burnt by the pretreatment. The coke preferably has a surface area of at least 100 m.2/g. and may have a density of 1.61-1.88 after pretreatment.  The coke is preferably produced in a fludized bed. It may contain 5-9 per cent or more of sulphur.  The oxygen-containing gas may be air or air admixed with oxygen, nitrogen or flue gas.  Part of the combustion product gases may be recycled.  The oxygen-containing gas may be used at atmospheric or superatmospheric pressure.  Production and isolation of carbon disulphide by known methods is described.  As shown, "fluid" coke having a sulphur content of 7 per cent, an average particle size of 350 microns, a surface area of 5 m.2/g. and a temperature of 1100 DEG  F. is passed via line 1 to vessel 3 where it is fluidized by an upward flow of air at a velocity of 1 ft./sec. which is introduced through line 7.  42,000 cubic feet of air per ton of coke are employed.  The temperature of the fluid bed is maintained at 700 DEG  F. by cooling coil 9.  After a residence time of 5 hours, 7 per cent of the coke is oxidized and the surface area of the remainder is increased to 130 m2/gm.  The pretreated coke passes via line 15 together with sulphur vapour to carbon disulphide production vessel 17 where the coke is reacted into fluidized gas bed while the combustion product gas, which contains residual oxygen, is passed via line 11 to a coke heating vessel 29 where it heats coke drawn from vessel 17 via lines 25 and 27 to a temperature of 1800 DEG  F. by heat transfer and partial combustion, after which the coke is returned to vessel 17 via lines 31 and 15.  Air is introduced into line 27 to increase the degree of combustion in vessel 29.  The temperature in the carbon disulphide production vessel may alternatively be maintained by the circulation of an inert solid carrier such as shot.  A small amount of nitrogen is introduced into the system via inlets 40, 41 and 42.  Flue gas is removed from vessel 29 via cyclone 33 and line 35 while carbon disulphide is removed from vessel 17 via cyclone 21 and line 23.
