Title: Magnetic beneficiation of clays utilizing magnetic particulates
IPC: C04B33/10
Filed: 1976-02-06
Abstract: 1530006 Magnetic separation ANGLOAMERICAN CLAYS CORP 6 Feb 1976 [1 Oct 1975] 04727/76 Heading B2J In a method for magnetically separating discolouring titaniferous contaminants of low magnetic attractability from a crude clay, a dispersed aqueous slurry of the clay is first seeded with a particulate of finely divided magnetic particles comprising either a ferromagnetic powder in which at least 50% by weight are less than 30 microns E.S.D., an aqueous precipitate of a magnetic ferrite of colloidal size, or a ferro fluid, and then subjected to a magnetic field to magnetically flocculate it, and at least part of the particulate together with the contaminants is removed. Preferably the resultant purified product is then leached, e.g. with sodium hydrosulphite, to remove excess iron, including at least part of the remnants of the seeding particulate. Preferably the magnetic particulate comprises a ferroso-ferric oxide formed by co-precipitating iron (III) with iron (II) salts, e.g. FeCl 3  . 4H 2 O and FeCl 3 , with an excess of a strong base, e.g. NH 4 OH, in which at least 50% of the particles by weight are less than 1 micron E.S.D. Alternatively, though apparently less effective, the magnetic particulate may comprisenatural magnetite, or a magnetic ferrite of the general formula MOFe 2 O 3  where M is a divalent metal ion such as Ni, Co, Fe, Mn or Mg. Conventional magnetic floatation apparatus may be used in the method but much lower than usual magnetic field intensities, e.g. down to 5 kilogauss, may be employed on the retention time of the slurry in the magnetic field may be reduced, e.g. down to 15 seconds. When in the magnetic field the slurry may be passed through a porous ferromagnetic matrix comprising steel wool, steel balls or steel tacks to effect the removal of the contaminants. Numerous comparative examples are given.

Title: Manufacture of oil gas
IPC: C10G11/22
Filed: 1954-02-18
Abstract: 751,510. Oil gas. SOC. DE CONSTRUCTION D'APPAREILS POUR GAZ A L'EAU & GAZ INDUSTRIELS. Feb. 18, 1954 [Feb. 20, 1953 ; April 16, 1953], No. 4851/54. Class 55(2). In a cyclic oil gas manufacturing process in which liquid hydrocarbons are cracked in the presence of a catalyst bed or mass the hydro. carbon is injected into a vaporizing chamber as a spray of droplets and hot gasification medium is introduced laterally with respect to the spray and so that it passes between the spray and the chamber wall the mixture then passing to the catalyst. In a plant-heating phase oil tar, or gas and air enter a combustion chamber a through inlets i k, excess air being admitted tangentially through an inlet l. The hot gases pass downwardly through vaporizing chamber b<SP>1</SP> and a catalyst bed from the top of which deposited carbon is burnt off. The refractory lining of the vaporizing chamber is swept by the gases entering tangentially. In the gas making phase steam or other gasification medium enters the heated combustion chamber through an inlet m and sweeps round a conical spray of liquid hydrocarbon from an atomizer d axially arranged in the vaporizing chamber. Gas generated within the catalyst bed is withdrawn through a pipe h to a washer. The two phases are separated by purging stages in which steam is passed through the gas making chamber. Refractory checkerwork may be placed in the combustion and gas making chambers and the connecting duct e, and the catalyst bed may be covered with a layer of small refractories. The vaporizing chamber may comprise a separate empty or packed chamber and be traversed by the heating gases before or after the gas making chamber. A steam boiler, air heater &c. may be interposed between the combustion chamber and gas making chambers. The heating and make gases may traverse the combustion and vaporizing chambers in opposite directions. Several superposed catalyst beds may be provided.

Title: Improvements in or relating to the flanging or beading of sheet metal plates, stripsand the like
Inventor: JOHNSON JACK STANLEY
IPC: B21D19/12
Filed: 1961-02-10
Abstract: 931,414. Beading; curling. WESTLAND AIRCRAFT Ltd. May 10, 1962 [Feb. 10, 1961], No. 4957/61. Class 83 (4). A tool for forming a bead or lip on the edge of a sheet or plate comprises outer and inner forming blocks wherein said bead is formed by first forming up one half of the bead or lip by forcing the edge of said sheet into a longitudinal gap of a semi-circular curved crosssection between said blocks and then forcing the edge of said sheet into a longitudinal groove of semi-circular cross-section in said outer forming block, thus causing said partially formed lip to curl in the groove to form a complete lip or bead. A beading tool which is mounted on a frame slidable on guides is actuated by an hydraulic jack and comprises an outer forming block 1 having a semi-circular groove 2 which is attached to a lower forming block 3. A rectangular inner forming block 4 having an abutment 5 and a stepped face 6 is slidably mounted on horizontal pins 7 mounted on a latch-plate 8 to which is attached a number of spigots 9 vertically slidable in the member 3. The spigots are connected via an arm 12, push-rod 13 and a follower 14 to a rotary cam mechanism mounted on top of the block 1 and comprising a driving cam 15 and a driven cam 16. The cam 16 is operated by a spring-loaded face-cam 17 attached to a rod 18, one end of which protrudes beyond the forward face of the tool. A spring 19 leads the block 4 towards the groove 2 and a spring-loaded ejector pin 20 is connected to a rod assembly 22 one end of which protrudes beyond the tool face. A spring-loaded latch pin 23 mounted on the plate 8 is connected via a lever arm 24 and a rod 25 to the cam 17. Operation.-In operation a sheet is clamped between platens and the tool advanced towards the sheet until the rod 18 abuts the upper platen and actuates the sliding cam 17 which rotates the rotary cam until cam 16 rests on the flat portion of the cam 17. Rotation of the cam 15 lifts the plate 8 to reduce the gap between it and the block 1 to a width greater than that of the sheet and allows the block 4 under the influence of spring 19 to move to the right and become locked in position by the pin 23. Continued forward motion of the tool causes the sheet to bend about the groove 2, when a quarter of the bead has been formed the cam 17 operates the rod 25 to release the locking-pin 23 from the block 4 which is then withdrawn against the spring 19 by the action of the rod 22 abutting the platen and operating the rod 20, as this takes place a complete bead is formed by the bending of the sheet edge around the groove 2. On completion of the beading the cam 16 runs off cam 17 thus allowing the plate 8 and block 4 to be lowered and removal of the tool allows it to reset. For high operating speeds hydraulic, mechanical or electrical tool control means may be used.

Abstract: 1,162,491. Fluid digital systems; electric selective signalilng. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 3 Feb., 1967 [4 Feb., 1966], No. 5035/66. Headings G4H and G4P. In a gauge for determining the extent and direction of movement of a body, the body 10 i.e. a slide or disc, is provided with equidistant holes 11, 12 inclined alternately in opposite directions, a fluid supply at 14 and a bi-stable switch arrangement 13. In use, if the slide is moved to the left to align outlet 21 and conduit 15 with a hole 12, then there is a pressure buildup at 17 causing flow to switch to passage 16; thus as the body 10 is moved further to the left, passage 16 is aligned with the next hole 11 causing a build-up at 19 and subsequently the fluid flow switches back to conduit 15. Hence a series of pulses are fed out at 22. Conversely, if the slide is moved to the right a series of pulses are fed out at 23. The apparatus may be electrical in which case the holes are replaced by conductive channels connected to a switch and relay system.
