Title: Production of metal oxides
IPC: C01B13/22
Filed: 1961-03-08
Abstract: <PICT:0981183/C1/1> A metal oxide is prepared by the oxidation of a volatile metal halide in a process comprising establishing separate, but communicating, first and second reaction zones, forming outside said zones an ignitible mixtute of solid, combustible material, having a particle size of less than 5 microns and a hydrogen content of less than 5% by weight, and an oxygen-containing gas, projecting the ignitible mixture into the first reaction zone, igniting it therein to produce a hot combustion gas, introducing a stream of a volatile metal halide into the second zone containing free oxygen, and passing the hot combustion gas into the stream of metal halide, said combustion gas being such as to ensure a temperature of between 900 DEG  F. and 2700 DEG  F. when contacted with the metal halide. The hot combustion gases are preferably introduced into the second reaction zone from a plurality of points at the periphery of the second reaction zone and which surround the metal halide stream. Preferably sufficient oxygen is introduced into the first reaction zone to both exhaustively oxidize the combustible material and to react with the quantity of metal halide fed to the second zone.  If desired, a separate stream of oxygen or air may be fed to the combustion zone.  Oxygen may also be introduced into the second zone with the metal halide and, in this event, the oxygen content of the ignitible mixture fed to the combustion zone may be reduced by the quantity of oxygen introduced with the titanium halide.  Specified combustible materials are carbonaceous fuels, e.g. carbon black, coke, petroleum coke, gas coke, charcoal, anthracite and bituminous coal, and sulphur and naphthalene.  Solid aluminium in the form of the metal or a salt of aluminium is advantageously mixed with the combustible material in the ignitible mixture so that when the resulting mixture is ignited the aluminium is oxidized to extremely fine particles of Al2O3 which are projected into the second reaction zone suspended in the combustion gases. An inert gas may be introduced into the second reaction zone surrounding the point of introduction of the metal halide stream. The term "metal oxide" is defined as an oxide of a metallic element or an element which exhibits metal-like properties of Group III or IV of the Periodic Table ("Large's Handbook of Chemistry," 8th Edition (1952), p. 54) which forms a volatile halide, e.g. silicon, titanium, zirconium, tin, aluminium, thorium and hafnium.  As shown in Figs. 1 and 2, a metal halide and an inert gas are fed through tubes 58 and 60, respectively, into central shaft 54. An ignitible mixture is fed through tube 72 to reaction chamber 64, where it is burnt, and the hot products of combustion, including free oxygen, are passed through slot 78 to central shaft 54.

Title: A machine for shearing sheet material
IPC: B26D1/04
Filed: 1962-03-06
Abstract: 937,148. Shearing. PIRELLI S.p.A. March 6, 1962 [March 11, 1961], No. 8528/62. Class 83 (4). A shear comprises a circular blade co-operating with a straight blade, the circular blade being mounted for movement relative to the straight blade and rotating so that the peripheral speed of the circular blade is slightly higher than the speed of said relative movement, the plane of said circular blade forming a small angle with the plane of the straight blade. Rotatably mounted on a base 1 is a lower ledger 2 on which are mounted double acting cylinders 3 and 4. The piston-rods 5 and 6 of the cylinders are connected to an upper ledger 7, and each rod has rack teeth formed on a part thereof, which engage pinions 11 and 12 mounted at each end of a shaft 8, so that the upper ledger remains parallel to the lower ledger. Mounted on the upper ledger is a motor unit 13 and gears 14, 15, 16 which drive a chain 19 whose ends are fastened to a carriage 20 which can slide along the upper ledger. The carriage 20 comprises a collar 27 which pivots about a pin 28 and is controlled by a single-acting cylinder 30 working against a spring. A spindle 38, 39 is mounted in the collar and carries a gear 41 which incorporates a ratchet device, and which is driven, through an idler gear 42 by rack teeth 43 extending along the upper part of the ledger 7. At the lower end of the spindle 38, 39 is a bevel gear 44 which drives a gear 45 on a shaft 46 which carries a disc 49 to which is secured a rotary cutter 50 which has a small rake on each of its surfaces. The straight blade 51 is mounted on a beam 52 which extends along the upper ledger 7 and is connected thereto by studs 55 and 56. There is lost motion between the studs and the beam, and the lower position of the upper ledger 7 can be determined by set-screws 63 and 64. An air-bag 68 is positioned under the upper ledger and acts on a bar 69 which has a member which extends to a point adjacent the cutting line and is provided with teeth 70<SP>1</SP>. To facilitate detachment of the teeth from the material to be cut there are springs 71 on the underside of the bar 69. There is an L-shaped bar 72 fastened to the lower ledger 2. For feeding the material to be cut there is an endless conveyer belt 73 which is driven by a carriage 81 which slides along a frame 82. The carriage supports a ledger 84 which can rotate in the horizontal plane with the cutter bar assembly, and which carries an air bag 88 and a presser bar 89 provided with an extension 90. The carriage is reciprocated by a double-acting cylinder 95 which acts through a two-to-one rack-and-pinion multiplier 92, 93, 96. A stop 97 adjusted by a screw 98 limits the rear-ward travel of the carriage, the stop itself comprises a single-acting cylinder 100 and a stem 101 which forms the actual stop member. The movements of the machine are controlled by limit switches acting through relays on electrically operated valves controlling the compressed-air cylinders.

Title: Improvements in or relating to railway vehicle brakes
IPC: B61H13/32
Filed: 1956-03-20
Abstract: 791,264. Brake transmitting mechanism. SVENSKA AKTIEBOLAGET BROMSREGULATOR. March 20, 1956 [March 25, 1955], No. 8705/56. Class 103 (1). In a braking apparatus for railway vehicles in which the leverage can be varied by means of links 5, 6 connecting levers 3, 4 of the fluid pressure brake cylinder 1 and in which link 5 gives a higher leverage when the wagon is loaded and link 6 gives a lower leverage when the wagon is empty, the lost motion in the latter linkage is reduced by an abutment 11, contained in housing 9, which may be moved into the path of an abutment 12 on link 6 so that the lower brake applying leverage is brought into action when the wagon is empty. Unlike the embodiment described in Specification 426,779, the abutment 12 is formed a fixed distance Sx from the movable abutment 11 so that the residual lost motion of the link 6 when abutment 11 is in its operative position and the brake is entirely released has a fixed value which cannot be adjusted. The brake rigging also incorporates an automatic double-acting brake slack adjuster 20 which is actuated by its control mechanism in direct dependence on the movement of the brake piston so as to adjust the brake shoe clearances at each release of the brake. By means of the above arrangement it is possible to use a simple type of triple valve and the necessity of separate adjustment on each wagon of the lost motion of the connecting link giving the lower brake applying leverage is avoided. Specifications 356,865, 530,658, 683,673 and 768,599 also are referred to.

Convention date, March 27, 1929. [Class 60.] Rollers, spindles, rods, tubes, and the like, treating; spindles and spindle mountings.-In a machine for grinding the external surface of a cylindrical article concentric with a bore therein or with predetermined centres, the work is supported at its ends s o n rotary holders and is driven by contact with a regulating wheel situated in opposition to a grinding wheel. The machine comprises a base 20 supporting a grinding wheel 22, and carrying a slide 23 upon which is a second slide 24, both slides being movable towards and from the grinding wheel. The slide 24 carries a regulating wheel 26 mounted on a hollow spindle 35 supported by antifriction bearings 33 in a frame 31, which is pivoted on a trunnion 30 to a frame 29 on the slide 24 and is movable towards the work about the trunnion by a spring plunger, to an extent limited by an adjustable screw. The wheel 26 is driven from a shaft 27 through an Oldham coupling 50; the frame 31 may be locked to the frame 29 by a screw 91. The work piece 62 is supported, during grinding, by engagement with the bore therein, by the tapered ends 60, 70 of members rotatably carried, with interposed ball bearings 63, 71, by shanks 57, 69 engaging respectively a bracket 56 on the slide 23, and a bracket 67 of a slidable member 66, moved by links 73 and a rock shaft 72, by the engagement of a pin on a lever 75 with a link 74 which rotates the shaft 72. The lever 75 is secured to a sleeve 76 screwed internally to engage a screwed shaft 54, so that, on rotation of the sleeve by the lever, the slide 24 is advanced, and simultaneouslv the slide 66 is moved. The slide 66 is connected by a pin 83 and a slot to a slide 77 having a V-shaped recess, upon which the work is placed when the slide 77 has moved up to a stop 82 as the regulating wheel is retracted, by the lever 75, to its extreme outward position. Reverse movement of the lever advances the regulating wheel and slides and at the same time causes the members 60, 70 to lift the work off the slide 77 for engagement and rotation by the regulating wheel. The slides 23, 24 are coupled together by a spring 86, and forward movement, determining the size of the work, is limited by a stop 88, the regulating wheel, during grinding, having a floating engagement with the work. In a modification, instead of the stop 88, the slide 24 has a lug for co-operation with an abutment on the slide 23.
