Patent GB-1043252-A (GB)
Title: Clay bleaching
IPC: C04B33/10
Filed: 1963-03-19
Abstract: The colour of a clay is improved by treating an aqueous slurry thereof with a reducing agent capable of reducing ferric to ferrous ions and a water-soluble polyfunctional organic compound one active group of which is -SH or -OH, and another active group of which is capable together with the -SH or -OH groups of chelating iron, the organic compound-iron complex being separable from the treated clay, and having a sufficiently low degree of dissociation to prevent oxidation of the ferrous ion. In some examples, alum is also present in the treating solution.  The clay may be kaolin. The reducing agents may be water-soluble hydrosulphites, the reaction products of water-soluble hydrosulphites with aldehydes, or hydrazine.  The polyfunctional organic compounds may be mercaptoacetic acid, thiomalic acid, mercaptoethanol or hydroxyacetic acid. The polyfunctional organic compound may be recovered by treating the mother liquor with H2S, Na2S or NH4OH after removal of the treated clay, thus precipitating iron sulphide or hydroxide.  Any Na2S or H2S remaining in the solution after iron sulphide has been removed may be oxidized to a reducing sulphoxylate, and the solution of reducing compound and regenerated iron complexing agent recycled.

Title: Method of and apparatus for manufacturing inflatable torus-shaped articles of synthetic rubber
IPC: B29D23/24
Filed: 1955-04-18
Abstract: 775,397. Making inner tubes &c., of synthetic rubber. GOODYEAR TIRE & RUBBER CO. April 18, 1955 [Nov. 16, 1954], No. 11063/55. Classes 70 and 87(2). In a method of manufacturing an inflatable torus-shaped article of synthetic rubber, e.g. an inner tube, in which the ends of an unvulcanized tube are spliced and the tube subsequently vulcanized in a mould in an inflated condition, separation of the splice during vulcanization is prevented by inflating the tube prior to vulcanization whilst restricting expansion of a portion of the spliced area to a radius less than the normal radius of the tube when inflated during vulcanization. The spliced unvulcanized tube 4 is placed on a supporting ring 5 with its spliced portion located where a bracket 7 bolted to the ring 5 carries a pivoted frame 16 surrounding a wire mesh member 20. The frame 16 is then moved to the position shown in Fig. 4 where it is secured by a latch 17. The tube 4 is then inflated to be restrained into an oval section in the plane of Fig. 4 by the mesh 20 and the ring 5. The engagement of the inflated tube with the wires of the mesh 20 prevents any excessive expansion that would separate the splice. The tube 4 is held thus for a predetermined period before being removed from the ring 5, placed in a mould, and vulcanized.

Title: Improvements in or relating to weft-bobbin changing apparatus for weaving looms
IPC: D03D45/20
Filed: 1958-04-08
Abstract: 849,754. Bobbin-replenishing looms. FISCHER A.G., G. April 8, 1958 [April 8, 1957]. No. 11134/58. Class 142(2). In a weft replenishing loom having bobbins arranged round the periphery of a rotary magazine in groups, each group containing one bobbin of each type (e.g. colour), the magazine is rotated when replenishment is called for by pawl-andratchet mechanism, there being one pawl for each type of weft in a group, the appropriate pawl being moved to engage the ratchet wheel by the energizing of a solenoid upon the closing of a contact dependent upon the position of the drop boxes. Replenishment is initiated by a weft feeler engaging the bobbin in the shuttle and the appropriate solenoid 69 a, b, c, or d, energized and a lever 73 a, b, c, or d, presses the appropriate pawl 23 a, b, c, or d, into engagement with its ratchet wheel. The solenoid also moves a finger 36 which lowers a lever 34 into engagement with a lever 39 driven by a cam 44 on the tappet shaft 45. A plate 30, carrying the lever 34, is thereby swung and a rod 125, lever 28, and spring 27 cause a further lever 29 carrying the pawls 23 to turn and thereby rotate the magazine. The pawls, which engage a tooth 25 on the magazine, are of different length to permit selection of the type of bobbin to be transferred. A roller 13 prevents free movement of the magazine and a detent 15, moved by a spring and a cam 19 on the lever 29, engages teeth 120 and arrests the magazine. Movement of the plate 30 also causes a member 46 to swing a warp protector 58, and a latch 72 to engage a slot 74 if the magazine is correctly positioned. Movement of the member 46 causes a lever 50 to move a member 54 until a pin 55 is in position to be struck by an abutment on the slay and thereby pivot the transfer hammer 129 on a lever 57. If bobbin transfer is prevented, ratchet mechanism or a spring loaded gear wheel returns the magazine to its initial position. A lever 66 prevents a bobbin from falling from the magazine until the lever is swung by a cam 75 on the plate 30. In a modification, each pawl 23 has its own stepping wheel and all the pawls could be of the same length.

Abstract: 141,203. Herbert, E. G., and Fletcher, C. May 6, 1919. Reciprocating-saw machines. -In a hack-saw machine, the blade b is set with its plane at an angle to that of its frame a to enable cuts to be made through metal bars transversely at various angles and longitudinally through bars of any length, and is arranged to work vertically through a slot in the work table c. The saw frame is carried by a slide k adapted to reciprocate in a guide-plate j arranged to rock on a bearing concentric with the driving-shaft g, one end of which is provided with a crank-disk l connected to the slide k by a connecting-rod m. The saw is fed through the work by the guideplate j rocking under the action of a spring p which is connected by a tension-adjusting screw o<2> to a sliding bar n pivoted to the plate i; the saw is enabled to rock through an angle on either side of the vertical. During the idle stroke, the pressure of the saw on the work is relieved by means of a dash-pot z which is connected to the guide-plate j and is constructed as described in Specification 29906/12, backward movement of the saw frame during the cutting stroke being effected by the means described in Specification 6414/12. A rod v<2>, supported on a rod v extending from the guide-plate j, supports an adjustable metal pipe w connected by a flexible pipe x<1> to a rotary pump x<2> which delivers lubricant to the saw blade from a tray e<1> at the base of the machine stand d, the used lubricant collecting first in a 'tray c<2> around the upper edge of the stand d, and then returning to the tray e<1>. The stand d is three-sided, and contains the saw-frame operating mechanism. When the saw is operating, the beltshifting rod s<3> is held by a weighted lever t engaging a notch in it, and when a cut is completed, an adjustable stop n<2> on the saw-frame rocking bar n disengages the lever t, permitting a spring u to shift the belt and stop the machine. A bar s<1> may be operated manually by a handle s<5> to stop the machine, an inclined surface on it disengaging the lever t. After the completion of each cut, the work-holding section of the table may be fed forward bv means of a screw.

Abstract: 487,714. Continuous production of water gas. 1. G. FARBENINDUSTRIE AKT.-GES. April 20, 1937, No. 11284. Convention date, April 21, 1936. [Class 55 (i)] In the continuous method of generating water gas rich in carbon dioxide by the gasification of solid fuel with steam, steam and oxygen, carbon dioxide-containing gas or other endothermically-reacting gas introduced in the lower part of the fuel bed in a generator, heat is supplied to the fuel bed by means of a heating gas, such as oxygen, oxygen-containing gas, or gases heated to a high temperature, for example, part of the water gas produced, supplied at a higher part of the fuel bed so as to form alternately hotter and cooler zones. The gases pass through the fuel bed in an upward direction. The gasification zones may be separated by intervals of 800 millimetres, and water gas rich in carbon dioxide is obtained, the composition depending on the starting materials, which may comprise wood, peat, lignite coal, pitch coke, cracking residues. &c. In an example, two zones are formed in a producer charged with brown coal briquettes by means of a gasifying medium comprising 300 kilograms of steam superheated to 900‹ C. and a heating medium comprising 100 kilograms of the same steam mixed with 20 cubic metres of oxygen, the water gas obtained being nearly doubled over that obtained in the of oxygen. In a modification of this example, the gasification medium is mixed with oxygen and the heating medium replaced by water gas superheated to 1100‹ C.
