Title: Improvements in and relating to optical instruments and devices for determining the average diameter of fibres in fibrous materials
IPC: G01N15/02
Filed: 1928-03-15
Abstract: 308,080. Ewles, J. March 15, 1928. Gauges-apparatus.-Comprises an instrument for measuring the mean diameter of fibre in a wisp of fibres by making use of the diffraction of light rays. A tube A of metal or other suitable material is fitted near one end with a diaphragm B. Telescoping into the tube A is a longer tube C fitted at the outer end with a readily removable eyepiece C1 formed as a cap C2 fitting over the tube C. A diaphragm C3 is also provided at the end of the tube C and is provided with a central viewing aperture in line with the aperture in the eyepiece. The diaphragm B is provided with a narrow slit B1 along a diameter, and parallel therewith, symmetrically arranged on either side, are pairs of small holes B2, B3. A tuft of fibres such as wool, cotton, &c. is laid across the eyepiece in the diametrically opposite slots C4 and the cap moved over the end of the tube with the fibres against the diaphragm C3, the cap being turned to bring the fibres into the plane of the slit B1. If the eye is applied to the eyepiece, and the device directed towards a source of light such as daylight or an opal glass electric bulb, a series of dark and light or of coloured bands is seen. The tube C is now adjusted longitudinally until the centre of the first dark band, or say red band, nearest the slit lies on one pair of holes B2 or B3. The position of the edge of the outer tube on the scales will then give the average diameter of fibre in the sample. The scales are calibrated by using fibre of known diameter. In a modification, the diaphragm B has a central circular aperture and the small holes are positioned on a concentric circle, the bands being seen as concentric circles.

Title: Improvements in the conversion of salts and more especially fertilizers and the likeinto globular or similar shaped bodies
IPC: B01J2/06
Filed: 1928-03-16
Abstract: 313,652. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 16, 1928. Drawings to Specification. Spray, freezing.-In the method of obtaining globular solid particles of salts, more particularly calcium nitrate or other fertilizer, by spraying the solution or melt in drops into a cooling liquid, the cooling liquid is rotated about a vertical axis within it so as to obtain a relatively long cooling path with a small quantity of the liquid. A fine powder such as chalk, gypsum, clay, talcum, kieselguhr, or magnesium silicate may be suspended in the cooling liquid so as to form a non- adhesive coating on the solidified particles, or a substance may be added which forms by reaction a protective film on the salts, for example barium hydroxide in the case of calcium nitrate melts. Alternatively or in addition to the powder, a paraffin or other oil or wax insoluble in water may be dissolved in the cooling-liquid. The melt may be fed through adjacently disposed nozzles, or be led on to an horizontal or slightly inclined rotating disc serving to direct the drops into the liquid, which by means of a stirrer or otherwise is given a paraboloidal rotating surface. Carbontetrachloride is mentioned as a suitable cooling liquid for a calcium nitrate melt containing 12.5 per cent of water, and 3 parts per 1000 of finely ground calcium carbonate may be added to the cooling liquid, with or without 3 parts of paraffin oil. Specification 233,720, [Class 82 (ii), Washing granular &c.], is referred to.
Patent GB-602510-A (GB)
Title: Improvements in creaming of synthetic rubber latices
Filed: 1946-03-15
Abstract: Alkaline aqueous emulsion polymerizates of butadiene-1,3 polymers and copolymers are creamed by adding a small amount, preferably less than 2 per cent, of glue to the polymerizate, reducing the pH to between 4.5 and 6.5 without irreversibly coagulating the same, raising the pH to about 9 and creaming with a hydrophilic colloidal creaming agent. The reduction of pH is preferably effected by the addition of sodium silicofluoride or by an ammonium salt such as the chloride or acetate followed by formaldehyde, and the pH raised by ammonia or dimethylamine.  The polymerizates may be polymers of butadiene-1,3, methyl-2-butadiene-1,3, piperylene or 2,3-dimethyl-butadiene-1,3; or copolymers of these compounds with substances containing a CH2=C=group such as styrene, vinyl naphthalene, a -methylene carboxylic acids and esters, nitriles and amides such as acrylic acid, methyl acrylate, acrylonitrile, methacrylonitrile, methacrylamide, and isobutylene.  In examples of the preparation of suitable copolymers, 75 parts of butadiene-1,3 and 25 parts of styrene were emulsified either with soap flakes or with potassium ricinoleate and then an oxidizing catalyst and an aliphatic mercaptan regulator added and the emulsion polymerized, residual monomers are removed by steam distillation.  The creaming agents may be alginates, particularly the ammonium salt, locust seed or carob seed gum, pectates, Karaya gum or Irish moss.  Stabilisers such as dodecyl sodium sulphate and potassium oleate may also be added.ALSO:Alkaline aqueous emulsion polymerisates of butadiene-1, 3 polymers and copolymers are creamed by adding a small amount, preferably less than 2 per cent, of glue to the polymerisate reducing the pH to between 4.5 and 6.5 without irreversibly coagulating the same, raising the pH to about 9 and creaming with a hydrophilic colloidal creaming agent.

Filed: 1928-03-16
Abstract: 317,496. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). March 16, 1928. Emulsion, making.-Bituminous dispersions of a somewhat coarse nature are prepared by the use as dispersing agents of water-insoluble humic acid or substances containing humic acid, the products being mixed with road-making materials or with materials such as plaster of Paris to form waterproof coverings. The substance defined as " containing humic acid " comprise (1) aqueous suspension of the raw material, such as Cassel brown, peat or decayed vegetable matter, from which humic acid is extracted; (2) products prepared by oxidizing coal, coal-tar pitch or the like, with nitric acid, chromic acid or the like; (3) oxidation or chlorination products of the substances referred to in (1); (4) calcium, magnesium, aluminium, iron or other insoluble salts of the compounds referred to in (J), (2) and (3). Examples of the invention are as follow (1) To 100 parts of brown coal, finely ground with 50 parts of water, are added with stirring 500 parts of Mexican bitumen and 350 parts of water. The mixture is applied to the road by means of a water-cart and is then covered with basalt chips. (2) 100 parts of brown coal, 30 parts of slaked lime and 120 parts of water are ground together and 500 parts of a mixture comprising 150 parts of tar, 350 parts of Mexican bitumen and 250 parts of water are slowly added. The product is mixed with 4,000 parts of basalt road metal, 3,000 parts of basalt chips and 2,000 parts of sand to form a road surfacing composition. (3) 500 parts of Mexican asphalt at 90‹ C. are added, with 350 parts of cold water to 150 parts of finely ground 30 per cent humic-acid paste. equal parts of basalt chips and sand are mixed with 12 per cent of the above product and 5 per cent of cement to form of a composition which may be applied to and rolled on roads and the like. The cement causes a rapid solidification of the mass. (4) To the mixture as in (3) 5 per cent of crude gas-tar are added. The mixture is thereby rendered quicker setting. (5) Waterproof gypsum boards for covering walls, ceilings &c. are made by coating a framework of reeds or laths with plaster of Paris containing 10-20 per cent of the product obtained in (3). (6) 100 parts of coal are digested at ordinary and then at elevated temperature with 100 parts of 50 per cent nitric acid until evolution of red vapour ceases. The mass is then washed with water and the insoluble residue dissolved in caustic soda solution and precipitated with hydrochloric acid. The resulting blaakish-brown paste is washed and filtered. 50 parts of the product are mixed with 200 parts of molten tar, containing 60 per cent tar pitch and 40 per cent anthracene oil, and 150 parts of water, to form an emulsion which may be mixed with 50 times its weight of basalt chips.

Patent GB-447318-A (GB)
Title: Improvements in and relating to refrigerating machines
IPC: F25B31/02
Filed: 1935-06-14
Abstract: 447,318. Rotary compressors. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. June 14, 1935, No. 8243/36. Convention date, June 14, 1934. Divided out of 447,859, [Group XIII]. [Class 110 (ii)] In a refrigerating-plant, a compressor has outwardly-sliding vanes which do not take up a loading position until oil under pressure from a second pump seals each end of the pump rotor and also forces out the vanes to make contact with the working chamber bore. The compressor is contained in a block 43 and is driven by an electric motor 37 by a shaft 38, which also drives an oil pump 58 which delivers oil from a sump 30 to counter-bores 66, 67, and to slots 53a behind the vanes 53, for sealing, lubricating, and vane-ejecting means. A spring 61 presses the diametral vane 59 of the oil pump, against a plate 47. The oil passes through a strainer 63 to an inlet 62, and is delivered through conduits 64, 65, to the compressor. The compressor rotor has vanes 53 which force refrigerant from an intake 56 provided with a strainer 57, to a delivery pipe 18 by way of a valve 54. The refrigerant re-enters the casing 15 through a pipe 29. Members forming casings for motor and compressor may be welded together as at 41, 44, 46. The leading edges of the blades 53 are rounded 53b in order that compressed gas in the working chamber will provide a small radial component of force tending to move the vanes inwards. The trailing edges of the vanes are relieved to reduce friction. To provide a substantialy constant pressure in the oil passages, the oil is delivered to a chamber 69 and forced through a sharp-edged orifice 68 in a vessel 72. Refrigerant vapour collecting in the latter vessel will form a cushion to damp out pulsations in the oil flow. The oil passes down a pipe 31 to be cooled, and re-enters the casing through a pipe 73 into a depression 74 from whence it flows over a hood 75, and past a baffle 42, which it cools, and falls to the sump 30. The space below the shell 75 is filled with refrigerant vapour which is circulated by a fan 37a for cooling purposes.
