A fertilizer is coated with 2-20% of a composition comprising 45-85% of a polyene polymer containing vinyl groups and 10-50% of a drying oil containing at least two conjugated double bonds in the molecule and the coating is cured. A slow-release fertilizer is thereby produced. The composition may also contain 5-45% of a lipophilic aminoplast precondensate. The fertilizer may contain an alkali metal, an alkaline earth metal, ammonium, phosphate, nitrate, chloride, sulphate, carbonate, or urea. The polymer may be derived from butadiene, isoprene, piperylene, 3-methyl-heptatriene-1,4,6, or w-decatriene-1,5,9. Copolymerization may be effected with up to 50% of ethylene, propylene, butylene, isobutylene, vinylacetylene, styrene, α-methylstyrene, acrylonitrile, an ester of acrylic acid or methacrylic acid, a vinyl ether or ester, or a vinylidene halide. The drying oil may be oiticica, castor, or wood oil. The aminoplast precondensate may be derived from formaldehyde and urea, thiourea, melamine, benzoguanamine, ammeline, guanidine, dicycanodiamide, glyoxyl monoureide or diureide, or N,N<SP>1</SP>-dimethylurea. The coating may be cured by heating at 60-150‹ C. for 2-20 mins. Curing may be effected in the presence of cobalt naphthenate as dryer, a peroxide or hydroperoxide as free radicalforming substance, or dimethylaniline as accelerator. A plurality of coatings may be applied.

Abstract: 1,053,628. Dispensing beverages. CORNELIUS CO. May 20, 1964 [March 16, 1964], No. 20837/64. Heading A4T. [Also in Division B1] An apparatus for dispensing fruit juice comprises a container 11 for carbonated juice 16 which container is fed with carbon dioxide from pressurized container 17, and dispenser 13 comprising chamber 14 for receiving the carbonated beverage from container 11, means for decarbonating the beverage and outlet valve 15. The means for decarbonating the beverage comprises pump 31 which withdraws the juice 24 from chamber 14 and recirculates it to chamber 14 via spray member 33. The chamber 14 may have air expelled therefrom through relief valve 26 by carbon dioxide from line 27 before allowing carbonated juice to pass into chamber 14. The passage of juice into chamber 14 is controlled by valve 22 controlled by float 23, this valve 22 being closed when the level of juice reaches the desired level. As the juice passes through valve 22 the pressure on the juice is reduced and the juice is subjected to a high degree of turbulence such that decarbonation begins. The temperature of the juice may be controlled by system 36.

Abstract: 1,227,822. Solution mining. INTERNATIONAL SALT CO. 2 July, 1968, No. 31618/68. Heading E1F. A method of solution mining of a subterranean deposit of a soluble mineral involves pumping a saturated solvent down to the deposit and allowing the solvent as it descends to absorb heat from the surrounding strata, which is at a substantially higher temperature, so that the solvent is no longer saturated when it reaches the deposit. The solvent is thus able to dissolve and absorbed some of the deposit as it passes through the deposit before being returned, whilst being maintained at substantially the same temperature and pressure as exists in the deposit, through an uptake for discharge into recovery apparatus, where a reduction of temperature and pressure of the solvent, allows separation from the solvent of the now excess mineral therein. Before the solvent is recycled to the deposit. Heat loss from the uptake is minimised by insulation or by passing hot solvent vapours from the recovery apparatus down and up through casing coaxial with the casing of the uptake before exhaust of the vapours to the atmosphere. U.S.A. Specifications 2,555,340, 2,876,182, 3,064,957 and 3,174,549 are referred to.

Abstract: 1,250,606. Fluid-pressure servomotor systems. NATIONAL RESEARCH DEVELOPMENT CORP. Nov. 14, 1968 [Nov. 15, 1967], No.52095/67. Heading G3P. [Also in Division F1] A hydraulic servomotor has a valve disc 46 Figs. 1 and 7 rotatable by a stepping motor 26 and provided with sixteen circumferentially spaced passages 57 the outer ends of which co-operate with two similar but staggered rings of passages 56 in a flange 47 of output shaft 33 and an endplate 42 rotatable with shaft 33. Passages 56 cooperate with rings of passages 50 in housing parts 2, 4, there being eight passages 50 in each ring which connect alternately with a supply manifold 6 or 8 and an exhaust manifold 7 or 9; each passage 50 ends in an arcuate port 50<SP>1</SP> Fig. 7. An extension 38 of flange 47 houses ball pistons 41 which can react against a cam track 16 to cause rotation of shaft 33. In operation, displacement of disc 46 relative to shaft 33 causes the cylinders 39 housing ball pistons 41 to be supplied or exhausted in a predetermined sequence, and thereby causes like rotation of shafts 33 through an angle equal to that turned through by the disc - at which point all the cylinders 39 are disconnected from supply and exhaust and shaft 33 stops. The maximum angle through which disc 46 can rotate relative to shaft 33 is defined mechanically or in the control circuit of motor 26. In the embodiment of Figs. 10 and 11, the input shaft 83 is connected to a cylindrical valve member 95 having an annular enlargement 96 which connects supply and exhaust manifolds 126, 125 in housing part 76 with a ring of nine cylinders 89 having ball pistons 90 co-operable with cam track 79 to rotate output shaft 88. The valve member rotates on a sleeve 75 having rings of passages leading from the manifolds. The inherent imbalance of the output shaft is compensated by providing a hydrostatic thrust bearing 161. Further hydrostatic bearings are provided at 164 and 167. The motors can be used to position lathe turrets and ships rudders, and can be so constructed as to be linear acting. The input can alternatively be mechanical, hydraulic, pneumatic or manual, and the cam track could be generated on a radial plane such that the pistons move axially of the motor.

[Also in Division F1] A discharge valve for a pressurized dispensing container comprises a one-piece plastics moulding, e.g. of polythene or nylon, and is either formed integrally with a plastics container, Fig. 8 (not shown), or is adapted to be mounted on a container. In Fig. 1; the valve is mounted in a container valve cup by flange 3, the cup either being attached directly to the container, Fig. 5 (not shown), or through an intermediate member, Fig. 4 (not shown). In mounting the valve, the flange 3 is biased from its concave shape shown to a flat shape, Fig. 2 (not shown), in which annular walls 4 and 5 are brought into engagement and valve member 7 is biased upwardly to close groove 13, subsequent depression of valve stem portion 11 moving member 7 downwardly to open groove 13 for flow between dip tube 10 and discharge nozzle 12. Groove 13 may be replaced by a passage extending through member 7 and opening on to wall 5, Fig. 5 (not shown). A number of passages may be provided with their openings axially spaced along wall 5, so that they are sequentially opened during depression of stem 11 to provide an increasing rate of discharge. In Fig. 10, wall 6 is biased against valve member 7, and is flexed away from member 7 by depressing stem 11. In Fig. 11, the valve has an annular passage 26 communicating with the valve stem 11 and opening to the valve member periphery through a peripheral slot formed between faces 4 and 5. A bias introduced during mounting of the valve acts to close the slot, which is opened by depressing stem 11. Sealing of the slot may be improved by an annular ridge formed on shoulder 6, Fig. 12 (not shown). In Fig. 13, the valve comprises a valve member 27 which, before use, is forced through constriction 6 so that wall 5 engages beneath wall 4, Fig. 14 (not shown), the resili-  ence of the web 2 biasing the walls together. Depression of stem 11 separates walls 4 and 5 for discharge to take place, a constriction 28 limiting downward movement of the valve member. In Fig. 15 (not shown), the actuating button is formed integrally with stem 11, an insert closing-off the top of the button.

Control of conditions in a heated steam chamber during the curing of dyed material is carried out by maintaining in the chamber a constant amount of liquid e.g. water in an open-topped vessel 65, the lower part of the vessel containing a thermometer 72 connected to a meter 74 outside the vessel. As liquid evaporates from the vessel 65 more liquid is supplied from a constant level tank 61 via a flow pipe 70, a heat exchanger 64 and flow meter 62, the liquid being maintained at a fixed temperature in the tank by thermostat 69 and the pipe having lagging 71. A fall or rise in either the temperature or rate of flow of the liquid indicates a need for adjustment in the injection of steam and indirect heat input into the chamber.
