Title: Improvements in a method for granulating urea
IPC: C05C9/00
Filed: 1953-10-14
Abstract: Granulated urea is produced by heating an aqueous solution of urea to a sufficient temperature to evaporate sufficient water therefrom to produce a 90-98 per cent urea concentration as rapidly as possible without allowing the solution temperature to exceed 100 DEG  C. for more than 5 hours nor to exceed 80 DEG  C. for sufficient time to produce more than 5 per cent biuret; then rapidly raising the solution temperature to from 115 DEG  to 130 DEG  C., if it is not already at that temperature, and spraying the so-concentrated and heated solution into a gas-cooled granulation tower, whereby round discrete urea granules are obtained; collecting said granules; subjecting collected granules to the action of heated air at a temperature below the softening temperature of said granules until the residual moisture content does not exceed about 0.5 per cent and cooling resultant granules to atmospheric temperature.  In an example, a urea solution is concentrated at 100-125 DEG  C. for 4 hours to a urea concentration of 95 per cent with a biuret content of 3.9 per cent, and the solution is sprayed at 118 DEG  C. and 100 m. Hg. pressure into a granulation tower through which air at 20 DEG  C. flows from the bottom; the particles so formed are changed to a rotary kiln drier and dried with air at 60 DEG  C., and then cool air at 5 DEG  C. is passed over the particles until the moisture content of said particles is 0.4 per cent.

Abstract: 1,164,111. Crate-tipping attachments for tractors. KENNETT HANDLING EQUIPMENT Ltd. 5 Oct., 1966 [5 July, 1965], No. 28468/65. Headings B8E and B8H. A box-emptying attachment for a tractor comprises a pair of arms 6 adapted to engage and be locked to projections 9 on the sides of a box and pivoted at 7 to arms 5 of a subframe 2 connected by a pivot 4 and a link to a main frame mounted on the loader arms or threepoint linkage of a tractor. The arrangement is such that the box is rotated to the emptying position shown by tilting the arms 5 from a substantially horizontal position to that shown. The arms 6 are rotated about the axis 7 by means of a linkage comprising a tilt link 15, pivoted at 16 to the subframe 2 and connected between a link 13, pivoted to a plate secured to the main frame, and a link 20 pivoted to an arm 21 which is pivoted at 22 to the arms 5 and which is connected by a link 23 to a part 24 secured to the arms 6. In operation, on tilting the subframe 2 and arms 5 about the pivot 4 by an hydraulic ram, the axis 16 moves in an anticlockwise direction about the pivot 4. The link 15 is caused to rotate in an anti-clockwise direction by the link 13 and causes the arms 6 to rotate in a clockwise direction when the arms 5 are substantially above the horizontal position. The projections 9 are held on the arms 6 by catches 10, as disclosed in Specification 1,164,112.

Steel is continuously produced from pig iron by introducing the molten iron in a stream into an evacuated reaction chamber in which it is divided into droplets and then treated with oxygen. As shown the vertical reaction chamber comprises upper and lower parts and lower crucible 6a, 6b and 6c, of stepwise increasing diameter. Molten iron is introduced from ladle 1 under control of plug rod 3 which is cooled by inert gas passing through duct 3a. On entering the chamber the subdivision of the stream takes place under influence of the vacuum and the inert gas stream and the drops are treated with oxygen introduced through line 10, molten steel collecting in crucible part 6c and being withdrawn through tap-holes 14 to casting apparatus. Slag is withdrawn through pipe 20 and the chamber is evacuated through pipe 16. Reaction accelerators such as boron, barium, niobium or steam can be added with the inert gas through duct 3a.

Abstract: A thermosetting resin composition comprises a resin based on vinyl chloride and an amide having more than one primary or secondary amido group in the molecule, said amide being a reaction product of an unsaturated dibasic aliphatic carboxylic acid and ammonia or an amine, and preferably a polyamide resin prepared by reacting di-linoleic acid with ethylene diamine.  The resin based on vinyl chloride may be polyvinyl chloride or a copolymer of vinly chloride with vinyl acetate, vinylidene chloride, butadiene, chloroprene, isoprene or acrylonitrile.  A plasticizer such as dioctyl phthalate, tricresyl phosphate, polychloroprene or a copolymer of butadiene with styrene, acrylonitrile or methyl isopropenyl ketone may be incorporated.  The composition may be dissolved in a solvent such as methyl isobutyl ketone and the solution used as an adhesive or cement or to produce textile fibres.  Other ingredients which may be present in the compositions include lead carbonate, basic lead phosphite, lead silicate, dibutyl tin di-laurate, lead stearate, lead phosphate, litharge and red iron oxide.  Cellular products can be made by incorporating blowing agents such as pp1-oxy-bis-(benzene sulphonyl hydrazide) in the composition or by dissolving a gas such as carbon dioxide or nitrogen in the composition under pressure.  The composition may be made by dispersing the resin in a plasticizer in which the amide has been incorporated. Specification 770,546 is referred to.
