Title: Automatic Yarn Hank Dyeing Machine.
IPC: D06B3/08
Filed: 1919-06-20
Abstract: 128,586. Textilmaschinen Fabrik Akt.-Ges. June 20, 1918, [Convention date]. Hank type.-In an automatic hank-dyeing machine, the hankcarrying rods 6 are moved in approximately elliptical paths E and are thus fed intermittingly along the upper toothed edges of the vat walls 4, while the tanks are fed forwards on the rods 6 by rotating the rods 32 about the rods 6. Similar travelling frameworks 2, 2<1> run on rails 3 along the sides of the vat 1, and each framework comprises a rodlifting fork 26, the stem 25 of which is reciprocated by the wheel 16 and link 30, while the guide 24 is reciprocated about its pivot 23 by the wheel 15, link 27, and plate 29, the path of the fork 26 thus being approximately elliptical. During this motion of the rod 6, the pin 41 is engaged by parts 36<2>, 38 of cam-driven three-armed levers 35', 36<2>, 37, and, together with the rod 32, is turned completely round the rod 6, thus feeding the hank forward on this latter rod. The various parts of the travelling frameworks may be driven by an electric motor 7 or by rope gearing, and motion may be communicated from the framework 2 to the framework 2<1> through the transverse shaft 20. The frameworks are caused to travel along the sides of the vat by the engagement of the pawl arms 36 or 36<1> with the racks 33 or 33<1>, there being provided a reversing-gear 13, 14 and a bolt for holding one or other of the pawl arms out of action. The feed of the tanks may be increased by using a tank-carrier constructed as shown in Fig. 7, and all the rods 6 may be raised and transferred to another vat by means of toothed lifting-bars 46. Specification 13982/11 is referred to.

Patent GB-1080210-A (GB)
Title: Improvements relating to the treatment of lateritic ore and the recovery of nickel therefrom
IPC: C22B23/02
Filed: 1966-04-07
Abstract: Nickel values in lateritic ores are concentrated by forming the finely-ground ore into pellets incorporating a sulphur-bearing material and one or more compounds of alkali or alkaline earth metals and heating the pellets in a tumbling bed at 850-1250 DEG C. in the presence of a reducing agent to reduce to metal substantially all the nickel and part of the iron and so form a product in which the ratio of metallic iron to metallic nickel does not exceed 10:1 by weight; the product is then finely ground and a metallic nickel concentrate separated therefrom by magnetic separation. The sulphur is preferably combined in the alkali or alkaline earth metal compounds e.g. as Na2 SO4, Na2S, Na2SO3, CaSO4 or CaS although it may be supplied in the elemental form or as pyrite.  Alternatively sulphur-containing reducing agents may be used.  The process is preferably effected in a rotary kiln and lime or dolomite may be admixed with the furnace charge.  The partially reduced product may be treated, before or after grinding, with steam or CO2 at 500-1000 DEG C. so that part of the metallic iron is reoxidized whilst the nickel remains in metallic form.  After magnetic treatment the concentrate may be leached with a carbonate-containing ammoniacal solution or treated pyrometallurgically to extract nickel and leave in the residue a nickel content which corresponds to the amount of nickel in the raw ore.  Metallic iron may be incorporated in the pellets as reducing agent; magnetic concentrate or the leached residue thereof may be used for this purpose.ALSO:In the concentration of nickel values in lateritic ores by controlled reduction and magnetic separation (see Division C7), the finely-ground ore is pelletized in the presence of water with a sulphur-bearing material and one or more compounds of alkali or alkaline earth metals, particularly sodium or calcium sulphate. The sulphur is preferably combined in the alkali or alkaline earth metal compounds, e.g. as Na2SO4, Na2S, Na2SO3, CaSO4 or CaS although it may be supplied in the elemental form or as pyrite.  Alternatively, sulphurcontaining reducing agents may be used.  The pellets may be dusted with lime or dolomite.

Title: Apparatus for use in the manufacture of tyres
IPC: B29D30/06
Filed: 1961-05-02
Abstract: 912,773. Moulding tyres. McNEIL MACHINE & ENGINEERING CO. May 2, 1961 [Aug. 19, 1960], No. 15839/61. Class 87(2). Apparatus for holding and inflating a plurality of tyres between pairs of closures during a period of cooling following vulcanisation comprises a trunnion carriage for mounting closure pairs in stacked relation and having a rotatable centre frame. In the device illustrated all operations are controlled by a master timer (not shown) and the apparatus deals with pairs of tyres simultaneously. Assume initially that four tyres are held in the device (solid line T's in Fig. 2) and that two tyres are undergoing vulcanisation in press 15. Shortly before the press is opened pressure fluid is bled from the lower pair of tyres and pressure fluid fed to cylinder 170 to unlock closure pairs 155. Pressure reduction to cylinder 128 separates the closure pairs and extends the down lift frame 92 (B in Fig. 2) discharging the tyres on to rollers 68 and, stop rollers 55 being depressed, thence to take-off conveyer 37. The press now discharges tyres T (dotted in Fig. 1) and the stop rollers 55 are elevated. Discharge of tyre is signalled by switch 41 operated by lever 38, 39. Correct positioning of tyre is indicated by switches 69, 72. The lower frame is then raised, closure pairs closed and pressure fluid supplied to the tyres. Conduit 208 equalises the pressure between tyres to ensure correct seating. The timer now actuates cylinder 103 and inverts carriage 90. The press then continues through its curing cycle and then repeats the above sequence, each tyre is thus maintained in an inflated condition during two complete press curing cycles. Specification 841,499 is referred to.

Title: Improvements in and relating to sewing machines
IPC: C07C205/57
Filed: 1939-05-30
Abstract: 529,334. Sewing-machines. NAHMASCHINENFABRIK KARLSRUHE AKT.-GES. VORM. HAID & NEU. May 30, 1939, Nos. 15858 and 15859. Convention dates, May 31, 1938, and March 4, 1939. [Class 112] Needles, vibrating laterally. - Mechanism giving a variable lateral vibration to the needle. arranged so that the stitches may be disposed symmetrically upon the line of sewing or entirely to one or other side of that line, is adjustable during stitching by means of a lever 46 which does not participate in the vibrations. The swinging needle-bar frame is coupled by a rod 39 to a block sliding in a slotted guide 31 carried by an oscillating lever 26. The guide is pivoted upon the outer extremity of the lever and is anchored, at a point in line with the axis of the lever, by a link 48 to an adjusting lever 46. With the lever 46 in its mid-position and the mechanism in its mean position, the slotted guide is concentric with the needle frame end of the rod 39 so that movement of the block upon the slotted guide 31 does not shift the centre of the zig-zag stitches. With the lever 46 moved to one side, the pivot 51 is moved laterally of the axis of the lever 26 and the centre of the zig-zag stitches changes with changes in the extent of the lateral vibrations. The block is connected by a link to a lever 77 in gear-tooth engagement with an adjusting hand-lever. The latter has an arm 75 which co-operates with a spring 76 having a central recess 77 and with adjustable screw stops which limit the maximum vibrations. The link 48 and pins 49 may be replaced by a suitable cam-slot in the lever 46 which engages the pin 51.

Title: Process for working up cellulose derivatives
IPC: C08J11/06
Filed: 1928-05-31
Abstract: 291,386. Eichengr³n, A. May 31, 1927, [Convention date]. Plastic compositions containing cellulose esters. -A process for working up cellulose derivatives into plastic masses for formation into sheets, ribbons, filaments, &c. consists in treating with a liquid which is substantially a non-solvent but which causes the cellulose derivative to swell up without losing its structure, pouring off the excess liquid, and converting the swollen mass into a plastic mass by heat or by the addition of a small amount of another non-solvent or a solvent. The swelling agent may he entirely non-solvent, or a non-solvent with the addition of a small quantity of a solvent, or a non-solvent only in the cold. Suitable liquids for use with acetone-soluble cellulose acetates are methyl alcohol, pure acetic ether free from alcohol, chloroform, ethylene chloride, and methylene chloride, alone or with small amounts of alcohol or of solvents. The resulting plastic mass may be formed directly into sheets, films, ribbons, &c. by rolling, extrusion, &c., or may be mixed with plastifying agents to give a kneadable mass, or with pulverulent filling material or colouring matter with or without softening agents to give a dry pulverulent or granular material which may be worked in moulds under pressure or mav be extruded througn apertures in a hot fluid condition. In one example, 500 grams. methylene chloride are poured over 100 grams. cellulose acetate and allowed to stand. After a few hours the excess liquid is decanted and 10 grams. of alcohol are added to the swollen mass which is heated and thoroughly agitated. The structure of the cellulose acetate disappears and the viscous syrup formed is kneaded with 20 grams. of triacetin and 75 grams of powdered talc, giving a hard brittle mass which is disintegrated and then moulded or extruded. In another example, for the formation of threads by extrusion, alcohol is added to benzyl cellulose and the mass subsequently treated with benzol. Specification 171,432 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following features :-(1), Artificial resins or other condensation products may be added in the incomplete condensation stage to the swollen mass. (2), Instead of the initial cellulose derivatives being treated with the swelling medium, pulverulent or finely disintegrated plastic materials obtained for cellulose derivatives may be similarly treated. (3), In a further example, alcohol and trchlorethylene are added to cellulose hydroacetate which is heated to 70‹C until a solution is obtained. On cooling a gelatinous mass separates out, the liquid is decanted and the mass is strongly heated with phthalic acid ester. The viscous solution gives on cooling a plastic mass which may be shaped between profiled rollers into filaments or bands. This subject-matter does not appear in the Specification as accepted.
