Abstract: 1,156,054. Operating a filter press. U. PASSAVANT A.G. [trading as PASSAVANTWERKE]. 24 June, 1966 [25 June, 1965], No. 28500/66. Heading B1D. During the filtering part of the operating cycle of a filter press 1, slurry is delivered to inlet 11 of the press by a pump 3 while some slurry is withdrawn from aperture 13, causing a flow of slurry through the aligned delivery apertures of the press plates which prevents their becoming clogged. In Fig. 1, aperture 13 communicates by flexible pipe 14 with a container 16 containing gas under pressure, and inlet 11 and aperture 13 are respectively located in the fixed and movable heads of the press. The press is filled by opening valves 5, 10, 15, pump 3 and the gas in container 16 forcing slurry in from both ends. As the pressure rises, pump 3 begins to force slurry back into container 16 again, compressing the gas. Valve 15 is closed and valves 7, 10 opened before opening the press. In other embodiments, not illustrated, container 16 may be replaced by another pump, or a press may be filled from the centre with a container 16 at each end or may be filled from both ends with container 16 connected -to a central plate. Container 16 may hold 20-300% of the filling volume of the press. In Fig. 2 (not shown), the container moves. with the movable head of the press. In Fig. 3 (not shown), there is a system (27 . . . 32) for applying filter aid to the press .plates before filling with slurry. Residual compressed air from the filter aid tank is delivered to container 16 to assist in filling the press. A manometer (24), connected across the ends of the press, opens a short circuiting valve (23) if clogging causes a sufficient differential pressure, so that the press is thereafter filled from both ends and filter plate fracture avoided.

Filed: 1951-12-05
Abstract: 701,137. Drawing. CALUMET & HECLA CONSOLIDATED COPPER CO. Dec. 5, 1951 [Feb. 12, 1951], No. 28534/51. Class 83 (4) A drawing machine comprises a frame, a pair of spaced drums rotatably mounted thereon, means for driving said drums alternately in opposite directions, means for securing end portions of the stock alternately to the drums for coiling the stock on one of the drums and uncoiling it from the other drum, and draw dies of different size successively engageable with the stock between said drums as it passes from one drum to the other. The drums 11, 12 are driven from a reversible electric motor 18 through clutches 17. Carriers 23, 24, carrying dies 27, Fig. 5, and guide bushings 29 are supported on a square section shaft 25 rotatable to bring a required die 27 into alignment with the path of the tubular stock S. The shaft 25 is also reciprocable in cylinders 40, 41 so that a plate 44, fixed to the shaft and carrying a series of wedge type clamping jaws 46, 48, moves in one direction or the other to grip the end of the stock projecting through a guide bushing 29 in one of the carriers 23, 24 and pushes it through a die 27 on the other carrier. The stock end is then gripped by a wedge type gripper 53 connected by a chain to a head 52 slidably mounted in a groove 50 in the drum on which the stock is being coiled. The carriers 23, 24 and plate 44 are mounted between end plates 33 and an arcuate side waU 32 having curved portions 39 engaging correspondingly curved recesses in a semi cylindrical cap part 37 supporting the assembly on the frame 10, so that the carriers may pivot about an axis perpendicular to the shaft 25 to allow the draw dies to align themselves with the stock. Lubricant is inserted into the end of the stock, before drawing, from a nozzle 70 and a plug 59, Fig. 7, of appropriate size is inserted into the tube end before it is projected through the die, to maintain the specified internal diameter of the stock. A spring 63 assists in maintaining the plug in position. Cutters 74, 75, having knives 75<SP>1</SP> are supported on the cylinders 40, 41, and may be selectively operated to cut off a deformed or damaged end of the stock before inserting a plug 59. The drums are shielded by fixed guards 67 and hinged, fluid operated guards 65. In a modification, Figs. 8-11 (not shown) a single die carrier is splined to a reciprocable shaft which carries an opposite side of the die carrier, two plates having gripping jaws for projecting the stock through the appropriate die. Drums 100, 101 may be positioned as axial extensions to the drum 11, 12, so that should the stock being coiled on either drum break, the stock on the drum would be shifted to the associated drum 100, 101 and the gripper 53 removed from the broken portion and re-engaged with the length of stock to be drawn.

Abstract: 976, 592. Coin-freed vending apparatus. RANK PRECISION INDUSTRIES Ltd. July 24, 1963 [July 26, 1962], No. 28754/62. Heading G4V. A coin-freed machine for dispensing sandwiches, confectionery &c. contained in pallets 1 arranged in stacked non-interlocking deposition in the machine has means for presenting the pallets one at a time to the customer upon insertion of a coin so that the vendable article can be withdrawn, the pallet however being prevented from withdrawal from the machine. The pallets 1 are stacked between guides 5 above a coin-freed drawer 8, the lowermost pallet resting by its lip 2 on guide supports 3. After a coin has been inserted, the drawer can be pulled along a channel 11 to carry the lowermost pallet to a position where the contents of the pallet are accessible to the customer; in this position, the pallet is prevented from being removed from the machine by overhanging lips disposed along the upper edges of the channel. During this movement, the pallet is caused to slide along the supports 3 and depress catches 6 against the pressure of springs 7 until the trailing edge of the lip 2 becomes clear of the catches. On the return movement of the drawer, the empty pallet is deflected under the supports 3 by the catches so that it will be free to fall into the lower portion of the machine; simultaneously, the stack of pallets is caused to descend until the next lowermost pallet rests upon the supports 3 ready for the next vending sequence.

Filed: 1936-10-22
Abstract: 483,663. Riveting. BECKER, E. Oct. 22, 1936, No. 28781. [Class 83 (iv)] Sets and snaps.-A method of flush or countersunk riveting, by means of a solid rivet having a head, which is not of preformed countersunk shape, consists in introducing the rivet through the perforated sheets, deforming the head to lie flush with the surface of the sheets on one side thereof, the head thereby forcing the edges of the sheets bounding the rivet aperture to form a substantially truncated conical projection on the other side of the sheets, and deforming the rivet shank to grip said projection. A flat die 2, Fig. 1, co-operates with a die 1 having a flat face 3, an inclined face 4, and a recess 5. Alternatively, the face 4 is omitted and the recess 5 merges into a recess 8. In the first stage of the operation, the rivet head is deformed to conical form, Fig. 2, the sheets are correspondingly countersunk, and the end of the rivet is upset by the die 1. A modified upper tool comprises a casing 11, Fig. 7, in which are mounted dies 13, 17 together equivalent to the die 1, Fig. 1. The die 13 is formed with a helical slot 16 so that it acts as a stiff spring, the die 17 being normally pressed outwardly by a spring 19. A recess 20 in the tool 17 receives the rivet shank and centres it. In a modified tool, the die 13 is replaced by a die 13a, Fig. 4, and springs 13a of part-spherical form. The tool 2 may have mounted therein a sleeve 23, Fig. 11, spring-pressed outwardly to form a guide for the rivet head before the operation, in combination with or alternatively to the centring recess in the die 17. The member 17 may be mounted in fixed relation to the casing 11. A ram carrying a centring depression may slide within a hollow body forming the die 17. The tools may be used in a handriveting operation or may be mounted in a compressed-air or other machine.

Title: Method of recovering nickel and iron from laterite ore by preferential reduction
Inventor: UEMURA MICHIO
IPC: C22B23/02
Filed: 1959-08-24
Abstract: Laterite ores are mixed with 1% of an alkali halide, 2-3% of a lime flux and sufficient carbonaceous reducing agent to reduce the nickel and part of the iron, and are smelted in an electric furnace to produce ferro-nickel and a chromium-bearing residue. The latter is then mixed with 15-30% of its weight of lime flux and 15-30% of its weight of a high alumina substance such as bauxite, and together with a carbonaceous reducing agent is smelted in a second arc furnace to produce a chromium-bearing pig iron and a slag which is suitable for the production of a high alumina cement.  The slag ratio in this stage is not less than 0.5.  The pig iron may be desulphurised in a rotary furnace at 1400-1450 DEG  C. using lime, and is then blown with oxygen in the same furnace at 1300-1380 DEG  C. using high basicity such as 2.5-3.5 with the addition of about 10% fluorspar as flux.ALSO:A slag suitable for the manufacture of alumina cement is obtained in a process for the treatment of laterite ore wherein the ore is first smelted to eliminate the nickel and some iron; the residue from this operation is mixed with 15-30% of its weight of a lime flux, 15-30% of its weight of a high-alumina substance such as bauxite, and together with a carbonaceous reducing agent is smelted in an electric furnace, the slag ratio being at least 0,5., and the slag composition about 50% Al2O3, 40% CaO, 5% SiO2.  The impurities such as CaS, CaC2 AIN are preferably eliminated from the molten slag by blowing for 5 to 10 minutes with compressed air, e.g. at a pressure of about 4 Kgm/cm2, and a rate of about 2 to 3 m3 (at N.T.P.)/minute.  The slag may then be held at a temperature between 1000 DEG C. and 700 DEG C. for one hour, before being cooled and pulverised.

Title: Process for preparing block polymers from alpha-olefins
IPC: C08F297/08
Filed: 1964-07-15
Abstract: A vapour phase block copolymerization process comprises the steps of (a) introducing to a continuously agitated reaction zone a preformed alpha-olefin polymer powder prepared from an alpha-olefin containing at least 3 carbon atoms, and containing active catalyst residues and less than 5% by weight volatile constituents; (b) introducing in vapour form one or more alpha-olefin monomers, at least one of which differs from that which said polymer powder was prepared, into intimate contact with said preformed polymer in said reaction zone; (c) continuously moving said preformed polymer from the inlet of said reaction zone to the outlet thereof while in contact with said monomer vapour, and polymerizing said monomer on to said preformed polymer; and (d) recovering from the outlet of said reacton zone a block copolymer containing up to 40% by weight of the total copolymer of copolymerized alpha-olefin monomer.  In a modification, the block polymerization is carried out in a series of two or more reactors. Suitable monomers include ethylene, propylene, butene-1, pentene-1, hexene-1, isobutene, 3-methylbutene-1 and 4-methylpentene-1; these (except ethylene) are also suitable for forming the preformed polymer, which may be obtained in powder form by polymerization in a hydrocarbon diluent and removing the solvent from the polymer slurry obtained.  The catalyst may be a mixture of a Group IVa, Va or VIa (Mendeleef) metal subhalide and an alkyl aluminium, preferably titanium tri-chloride, optionally cocrystallized with aluminium chloride, in admixture with, for example, triethyl aluminium or diethyl/aluminium monochloride.  A chain regulator, e.g. hydrogen, may be employed in the block polymerization.  Particular forms of apparatus are described for carrying out the process in a semi-continuous batch or continuous manner.
