Abstract: 912,680. Threading-up textile machines. SCRAGG & SONS Ltd., ERNEST. Sept. 29, 1961 [Dec. 6, 1960], No. 41954/60. Class 120 (2). A textile machine comprising means to deliver yarn at a predetermined speed and take-up means, is provided with a tube 21 connected to a source of suction and of which the end can be moved between the delivery and take-up means; accordingly the yarn can be drawn into the tube until it is satisfactory and then transferred to the take-up. The device may be applied to a crimping machine where a series of yarns are each drawn over-end from a package 11 by feed-rollers 13 and passed to a heater 14, a false-twister 15 and rollers 16 which deliver it to a take-up package 20. Between rolls 16 and the take-up packages is provided a vacuum line 17 with sockets 17a into one of which the tube is plugged. A handle is moved to make operative the corresponding rollers 13, 16 and twist-tube 15 and the yarn delivered at 16 is passed into the tube to be carried away. When the crimp is observed to be satisfactory, the tube is moved to the takeup, the yarn severed by a device 22, and applied to the take-up by the operator's finger. If two yarns are treated at each crimping station, the tube is applied first to one take-up and then to another when the delivered yarn is satisfactory. A fan on a carriage movable along the machine may replace the vacuum line 17.

Abstract: 1,163,111. Sack filling machines. W. C. HALLS, and A. C. MONK. 31 Aug., 1966 [31 May, 1965; 4 Oct., 1965], Nos. 23079/65 and 41989/65. Heading B8C. [Also in Division G1] Apparatus for filling sacks with weighed quantities of material comprises a single weighing platform for supporting two sacks at spaced filling positions and deflector means to deflect material to one or other of the positions in response to increase in weight on the platform due to a sack reducing the correct weight of material. Two sacks (12), (13), Fig. 2 (not shown), placed on the platform (11), Fig. 1 (not shown), of a weighing balance, are alternately filled with a predetermined weight of potatoes from a hopper (14). The hopper has one outlet 17, 18 for each sack, the outlet in use being selected by means of a movable flap 19 which may be preset by means of a hand lever 50, to operate at a given filling weight in one of the sacks. The flap 19 is freely mounted on an inner shaft (39) and a radial arm 48 on the flap is entrapped between the flanges 49<SP>1</SP>, 49<SP>11</SP> of a sector 49, fixedly mounted on the shaft (39). Sector 49 can rock between stops 42, 43. A spring 52, on an arm 51 of the lever 50, which has a pawl engageable in recesses 57, and 58 on a sector 41, urges the sector 49 towards stop 42, or 43 accordingly. Trip 60 is also secured on to the shaft 39 and is held by locking arm 63, or 64, according to the position of the sector 49, thereby preventing the shaft 39 from rotating. As the platform (11) descends under the weight of the filled sack, an arm (68) on the platform engages with a nut (70) at the bottom of shaft 65 to move the shaft downwards thereby causing shaft 61, and locking arms 63, 64 to rotate. The trip 60 is released, thus allowing shaft 39 to rotate and, due to the action of the spring 52, the sector 49 is pulled towards stop 43 carrying with it the flap 19 to close outlet 18 and discharge the produce through outlet 17 into the other sack. The operator removes the filled sack and replaces it with an empty one, whereat the platform (11) rises and arm (68) engages an upper nut (69) on shaft 65 to cause the shaft to rise which results in arm 64 engaging over the arm 74 of trip 60, thereby again locking the shaft (39). The operator moves the control lever 50 so that the pawl engages in recess 58, the spring not urging the sector 49 towards stop 42 and the cycle is repeated when the sack is full. Each outlet is surrounded by a rubber sleeve (36) which fits into the mouth of a sack, and the hopper is supported on brackets 30 mounted on a central pillar (29) of the weighing machine. A weight (72) on an arm (71) acts as a counterbalance for the trip mechanism. The flap may be moved by a solenoid, triggered by a photoelectric cell as the platform 11 descends. The filling machine may be mounted on a trailer towed behind the harvester.

Abstract: 423,794. Moulding screw propellers &c. STONE & CO., Ltd., J., Deptford, London, and CLAVEY, A. G., Kenilworth, Willett Way, Petts Wood, Kent. July 8, 1933, No. 19437. [Class 83 (i)] Moulding-machines; flasks; moulds ; cores.-A mould for casting a profiled object, such as a propeller blade, is made by forming a pitch surface on plastic which when dried and rendered smooth and impervious is used to make a second pitch surface in plastic, the two surfaces being finally used in producing cope and drag patterns. A base - plate 8 is fitted, by means of a tenon and slot 2, to a floor 1 and a vertical rod 4 thereof. The projected shape is built up from bricks, &c., on the base 8, covered with plaster, cement, &c., and shaped to a pitch plane by a blade 6 pivoted on the rod 4 and guided by a rail 7 mounted on the floor. When dry, the plaster is scraped by a similar blade edged with steel and a cavity 40, 41, Fig. 3a, the shape of the propeller boss and face fillet 34, Fig. 5, is struck out by a board on the rod 4, and scraped out to templets. Wall segments 10 ... 14 of a box 24 having an upper edge, roughly corresponding to the pitch plane, are built up on the base about this shaped bed, gaps between the bed and walls being filled up by hand. When dry the surface is varnished and is used for making another as follows. A segmental upper box 25, Fig. 2, (not shown), is placed on the box 24, filled with plaster, the whole inverted, the box 24 removed and the material in the box 25 dried and varnished. If a blade having its face in the pitch plane is desired, the box 25 is ready for forming drag moulds. The box 24 is then fitted with a boss-segment pattern 42, Fig. 3<a>, and sectional patterns 35 of a blade, the intervening spaces 37 being filled in with plaster, and shaped by hand as at 39, 411. When dried &c., this is used to form cope moulds. The moulds 24<1>, 25<1> are assembled on a floor 1<1>, Figs. 4 and 5, with radial grooves 2<1> and held by rods or rammed sand 28 in grooves 29. A head ring 30 and cores 31, 32, are then fitted by bolts 20<2> and 41, and one or more runners are arranged to enter at the bottom of the boss. For propellers with wide blades which overlap, boxes with inclined sides are used. The method may be modified to cast separate blades for a built up propeller. The base plate may in this case be inclined to correspond to the inclination of the blade and the side walls 11, 13 be of equal depth.

Filed: 1974-09-30
Abstract: 1464740 Measuring angular displacement electrically SIEMENS AG 30 Sept 1974 [25 Oct 1973] 42405/74 Heading G1N The rotor angle # of a frequency-converter-fed synchronous machine is indicated by a counter 4 fed by pulses from a disc 1 coupled with the rotor. An element 3a provides a synchronizing pulse but this operates only when the machine is running. To determine the rotor angle before starting the machine, pulses are fed from a pulse generator 8 to the rotor windings 5 and also to a simulator 7. From voltages UR, U S , U T  induced in stator windings W R , W S , W T  a component transducer 10 detects the angle α 1  of the stator voltage vector. The simulator 7 contains an element 11 simulating the excitation and an element 12 for computing the rotor-related angular position α 2  N  of a simulated stator voltage vector. This angle is combined with a rotor angle X, (initially random), in an angle adder 14 to give a stator-related angle α 1N . An angle comparator 15 detects any angular difference # and corrects the position of the counter 4 until # is reduced to zero. The position of the counter then shows the rotor angle #. The angles α 1 , α 2N , α 1N  and # are determined by the relative magnitudes of the sine and cosine components of the corresponding voltages.

Abstract: 1,189,122. Purifying polymers of episulphides. DUNLOP CO. Ltd. 21 Sept., 1967 [23 Sept., 1966], No. 42448/66. Heading C3R. Metallic catalyst residues in polymers prepared by polymerizing episulphides in the presence of such catalysts are removed by contacting the polymer with a mercaptan, having a molecular weight of less than 200 and which forms a metal mercaptide with the metal of the catalyst, which mercaptide is separated out from the reaction system. When the polymer contains a metal bonding two or more polymer chains, the apparent molecular weight is also reduced. The reaction system may comprise a solution of the polymer, or the polymer itself if liquid. Suitable solvents are hydrocarbons and halogenated hydrocarbons, and the metal mercaptide formed should preferably be insoluble in the solvent. The mercaptan may be a mono- or di-mercaptan, e.g. ethane dithiol, n-propyl mercaptan, n-butyl mercaptan and dodecyl mercaptan. The treatment may be repeated, particularly with low molecular weight polymers. The catalysts described are those disclosed in Specification 1,189,121.

Title: Improvements in defluorination of phosphates
IPC: C01B25/32
Filed: 1960-12-12
Abstract: Phosphate-containing materials are defluorinated by digestion with a mixture of phosphoric acid and at least one mineral acid more volatile than phosphoric acid and then subjecting the digestion liquor to spray drying or thin film drying (i.e. drying a film not more than one half inch thick) to evaporate the volatile constituents <PICT:0905375/III/1> and collecting the dry defluorinated phosphate containing less than 1 part of fluorine per 100 parts of phosphorus by weight. The volatile mineral acid must be capable of forming water-soluble calcium salts and should preferably be hydrochloric, nitric or perchloric acid; the weight ratio of the acid (calculated as equivalent to HCl) to the phosphorus (calculated as P2O5) in the liquor should be at least 0,3 : 1, preferably 0,7 : 1 to 1 : 1.  The amount of phosphoric acid added is such that the mole ratio of the total amount of calcium (calculated as CaO) to the total amount of phosphorus (calculated as P2O5) in the mixture is not more than 2,6 : 1 and preferably is within the range 0,9 : 1 to 1,1 : 1.  In Fig. 1, the phosphate material to be defluorinated, the phosphoric acid (preferably wet process phosphoric acid obtained by the action of sulphuric acid on phosphate rock), and the mineral acid, e.g. HCl, are introduced into digestors 4 together with optional additives such as reactive silica and trace amounts of iron, cobalt, copper or zinc. The amount of water present in the digestion mixture should be sufficient to form a solution containing between 20 and 50% by weight of solids.  The digestion liquor is transferred from settling tank 6 to a spray dryer 8 to leave a dried calcium phosphate product containing less than 5% by weight of volatile matter (The drying may alternatively be carried out in a drum-dryer or thin-film evaporator.)  Fluorine present in the effluent from the spray dryer is precipitated by sodium or potassium water-soluble salts, especially KCl, to leave a solution of HCl which is recycled to the digestion step after separation from the formed alkali metal fluosilicate.
