Title: Process for the preparation of granulated phosphate fertilizers
IPC: C05B1/04
Filed: 1963-05-09
Abstract: <PICT:1013950/C1/1> A granulated phosphate fertilizer, having a base of triple superphosphate, is prepared by mixing a substantially pulverulent triple superphosphate formed by treatment of phosphate mineral with concentrated phosphoric acid containing 46 to 55% by weight of P2O5, with a wet fluid superphosphate mass formed by treatment of phosphate mineral with dilute phosphoric acid containing 25 to 33% by weight of P2O5, and then granulating and drying the mixture.  Part of this final mixture, preferably that left after removing the granules of the desired size by a screening operation, may be recycled.  The fluid superphosphate preferably forms at least 20%, and the triple superphosphate in powdered form 70 to 85%, by weight of the final dry granulated triple superphosphate produced.  A supplementary fertilizing compound, e.g. a potassium salt, may be added to the mixture prior to granulation. The process may be carried out continuously by controlling the rate of flow of the reactants. In relation to Fig. 1, previously ground phosphate mineral is fed into mixer 4, from hopper 1 via feed conveyer 2.  Concentrated phosphoric acid at a controlled rate is fed into mixer 4. The mixture passes into rotatory drum 5, containing a scraper 6, and solidifies and is converted into powder form, and then passes into granulating drum 7. Phosphate mineral and dilute phosphoric acid are introduced into vat 11, and the thus-produced fluid superphosphate mass overflows into drum 7, where it mixes with the powdered triple superphosphate from drum 5.  This mixture is dried in 13, and screened at 16.  The granulated product of desired size is removed through 18, and the remaining particles are recycled to drum 7. Fig. 2 (not shown) includes a modification whereby a supplementary fertilizing compound may be introduced into drum 7.

Abstract: 1,110,862. Rotational moulding. L. H. BARNETT. 3 May, 1965, No. 18578/65. Heading B5A. In a machine for the rotational moulding of thermoplastic and thermosetting resins, charged moulds 20 are fed to and removed from a mould rotating and heating mechanism 10 by alternately operated vehicles 12, reciprocable along track 14. As illustrated in the Figure, two sets of the above apparatus may be located sideby-side the vehicles 12 of each set being connected by bridges 24 for synchronous movement. The mechanisms 10 each comprise a frame 22 supported by outer bearing members 18 and a common inner bearing member 16 for rotation about an axis 17. The frames 22 each carry locking mechanisms (see Figs. 11 and 12, not shown) which are adapted to support the axle 120 about which the moulds themselves are rotated. Suitable mechanisms for rotating the frames 22 and the moulds 20 are shown in Figs. 14-17 (not shown) and include motor and chain drives. The moulds are heated during rotation by, e.g. gas or the like burners 138 mounted for rotation with the frames 22. Alternatively electric or steam heating may be used and the heaters may be mounted for rotation with the moulds. Each of the vehicles 12 carries a vertically reciprocable framework (see Figs. 3 and 4, not shown) adapted to support a mould, a driven roller being carried by said framework so that the mould may be rotated during its removal from the mechanism 10 and its transfer along track 14 to an unloading station. The moulds are also cooled during the transfer by a blower or by a liquid coolant bath, both carried by the vehicles. In operation a set of vehicles loaded with charged moulds is forwarded under mechanism 10, the mould support frameworks raised, the moulds locked in position on frames 22, and then rotated about two perpendicular axes to perform the moulding. Meanwhile the previous moulds, which have been removed by the other set of vehicles, are cooled, rotated, and transferred to the unloading station. Instead of vehicles which move under the mechanism 10, vehicles which are suspended for movement above the mechanism may be used and if required instead of alternate operation of two sets of vehicles a continuous line thereof may be used.

Abstract: 399,622. Fluid-pressure brakes. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, GOODYEAR, E. F. and WRIGHT, J., c/o Dunlop Rubber Co., Foleshill, Coventry. July 2, 1932, No. 18769. [Class 103 (i).] In a pneumatic-hydraulic brake system, particularly for aircraft, liquid is forced pneumatically to apply the brakes into annular members distensible within the brake drums against pressure exerted on the annular members by a plurality of spring-loaded brake shoes. A pair of chambers 12<1>, each formed by a cap 12 and a flexible diaphragm 13 secured at its edge between the member 12 and a plate 19<1> integral with the casing of a valve device 19, are filled with liquid and connected each by a pipe line at 14 to one of the wheel brakes. By operating the valve device 19 compressed air is supplied through passage 18 from a container connected at 24 to the space between the diaphragm and the plate 19<1> whereby liquid is forced from the chamber 12 through pipe 20, Fig. 4, to the brake which comprises a distensible annulus 21 actuating radially movable shoes 22, that are released by springs 23 as described in Specification 379,529. The valve mechanism shown is that described in Specifications 397,895, 397,896, and 397,897, [all in Group XXXIII]. A finger lever mounted on a main control lever of the aircraft is connected by a cable to a pivot 26 slidable in a guide 27 and connected by links to the sliding valve operating member 28 of each brake. Movement of the member 28 in one direction or the other effects the opening of supply and exhaust valves 29, 31 for the compressed air. Unequal application of the brakes is affected by angular movement of the arm 11 which is connected to the rudder bar and turns the guide 27 into a position asymmetrical with respect to the two members 28.

Title: Process for the Production of Aromatic Hydrocarbons and a Fuel Gas from Petroleum Oils
Inventor: FOWLER RAY
IPC: C10G47/00
Filed: 1966-04-29
Abstract: 1,157,114. Aromatic hydrocarbons; fuel gas. POWER-GAS CORP. Ltd. 10 April, 1967 [29 April, 1966], No. 18907/66. Heading C5E. Aromatic hydrocarbons and fuel gas are produced by (1) reacting a heated mixture of a petroleum oil and hydrogen or a hydrogen-rich gas under pressure to produce aromatics from naphthenes and paraffins, the reaction being endothermic and being carried out in two or more stages at 800-1100‹ F. and 200-800 p.s.i.g. with reheating between the stages, (2) treating the products from the first stage, with or without added hydrogen, to effect hydrodealkylation of aromatics and gasification of paraffins, the reaction being exothermic, (3) cooling the products from the second stage, e.g. by indirect heat exchange with incoming feed for the first stage, and (4) separating condensed aromatics from a fuel gas containing normally gaseous hydrocarbons. Suitable catalysts for the first stage are bauxite, an oxide of molybdenum, cobalt or chromium, Pt/Al 2 O 3  or Pt/Al 2 O 3 -SiO 2 . Stage (2) may be non- catalytic at 1250-1450‹ F., or catalytic at 1000‹ F. or above, suitable catalysts being cobalt molybdate and nickel molybdate. Steam may be present in either or both of stages (1) and (2), in which case condensate water separates as a lower layer in the condensate from stage (4). The aromatic product may be fractionated first to remove dissolved gaseous hydrocarbons and hydrogen (which may then be used as a heating fuel in the system), and then to yield pure benzene, a benzene/toluene/ xylene mixture which may be recycled to dealkylation, and a higher aromatic fraction. The fuel gas product is preferably washed to remove aromatic hydrocarbons, which may be recovered, and part of the gas may be steam reformed to yield, after CO conversion and CO 2  absorption, a hydrogen-rich gas for use in stage (1).
