Heading C1A. Mono- and/or di-ammonium phosphates are obtained from ores containing phosphate and calcium ions by attacking the ore with nitric acid, extracting the reaction mixture with a polar organic solvent or solvents, purifying the organic solvent layer, ammoniating the purified extract to form a precipitate of mono- and/or diammonium phosphate, a light phase containing solvent and a heavy aqueous phase, decanting the light phase and recycling it to the extraction step, separating the ammonium phosphate precipitate, washing this precipitate, recycling the wash waters and part of the heavy aqueous phase to the purification step, and cycling the aqueous solution from the purification step to the extraction step. The organic solvent may be a branched or straight chain aliphatic alcohol containing 4 to 6 carbon atoms, e.g. OXO alcohols. As shown, phosphate rock and nitric acid are introduced into 3. The resulting solution is fed to zone 4, where it is cooled, giving tetra-hydrated calcium nitrate crystals which are washed in 5 and returned to 3. The mother liquor is fed to liquid-liquid extraction zone 8, where it is contacted with the polar organic solvent. The raw extract is fed to a second extraction battery, where it is contacted with recycled ammonium nitrate solution from 18. The purified extract is led to neutralization zone 13, reacted with ammonia gas, preferably so as to maintain pH 3.5, and the light phase (solvent, some water, traces of monoammonium phosphate) recycled in lines 15 and 9 to extraction battery 8. A crystal slurry is recovered from the base of 13, fed to 18, where the crystals are separated and washed, giving the ammonium phosphate in line 20. The wash water, together with some mother liquor, is recycled to 11. The aqueous phase leaving zone 11 is led to zone 8, and the raffinate leaving 8 is fed, together with the rest of mother liquor from 18 into distillation column 31, where organic solvent is removed from the top, passed through condenser 32, and recycled to 8. The raffinate, freed of organic solvent, is collected at the bottom of the column, and fed to zone 34, together with calcium nitrate tetrahydrate from 5, and treated with ammonia and carbon dioxide gases. The reaction mixture is filtered at 38, so removing calcium carbonate, and leaving concentrated ammonium nitrate solution.

A plate condenser comprises a plurality of parallel plates 1a, 1b, spaced apart by suitable peripheral sealing arrangements to define passages for fluid to be condensed alternating with passages for cooling water. The passages through which the fluid to be condensed passes include a plurality of inclined baffles 4a which act to guide condensed liquid drops downwardly, these baffles 4a being incorporated on the surface of the plates 1a. Vertical baffles 8 provided on the surface of plates 1b define a return flow path for the cooling water entering through inlet 6 and leaving through outlet 6b. The baffle 8 may extend the full length of the plate surface to define two separate water passages (Fig. 4B, not shown). The inlets 2, 2b, for the fluid to be condensed, which are shown to extend horizontally across the plates, may alternatively extend vertically (Figs. 8A, 8B) down one side of the plates. In a modification the plate 1a may be formed with inclined recesses in its surface acting to guide the condensed liquid downwardly either towards the sides of the plate (Fig. 6A) or towards the centre (Fig. 6C). In an alternative form the condensed liquid is guided by a series of ribs formed on both sides of an apertured intermediate plate (91, Fig. 9) disposed in the passages through which the fluid to be condensed passes. The peripheral sealing arrangement between adjacent plates, Fig. 10A, comprises a metal spacer 102 having a recess 107 therein for receiving a circular gasket. Alternatively, two recesses on opposite sides may each receive an oval gasket (Fig. 11).

Abstract: 1,258,808. Machines with permanent magnets. KELSEY-HAYES CO. 21 March, 1969 [16 Aug., 1968], No. 15128/69. Heading H2A. In an inductor-type rotational speed sensor, movement of the rotor alternately transmits flux to the sensing coil and shunts it away therefrom so as to produce maximum variation in the flux acting on the coil and hence a signal of high amplitude. In Fig. 1, the coil 26 is surrounded by an annular U-shaped stator 22 and the flux is provided by a permanent magnet 30 located between the stator and an annular member 36 which provides a flux return path. The ends of legs 32, 34 of the stator are formed with aligned teeth 38, 40, which face teeth 46 on the rotor 44, and member 36 has a cylindrical surface 42 facing a corresponding surface 48 on the rotor to provide a constant reluctance air gap 52. As shown in Fig. 3, the teeth 46 are skewed so that when in alignment with teeth 40 they are out of alignment with teeth 38. Thus as the rotor rotates, the flux is switched alternately through the leg 34 and the shunt leg 32. Instead of skewing the rotor teeth, circumferentially offset sets of teeth (38b, 40b), Fig. 5 (not shown), may be provided on legs 32, 34, or the skewed rotor teeth may be replaced by two sets of circumferentially offset teeth (46a, 46a<SP>1</SP>), Fig. 4 (not shown). Fig. 6 shows a modification in which the sensor has radial air gaps. The rotor 44c is disc-shaped and has two sets of circumferentially offset, radial teeth 46c, 46c<SP>1</SP> which cooperate with aligned teeth 40c, 38c on stator legs 34c, 32c as in the previous embodiments to switch the flux from magnet 30c alternately round the stator through leg 34c back to the central return ring 36c and through the shunt leg 32c back to ring 36c. The teeth 46c, 46c<SP>1</SP> may be aligned and teeth 40c, 38c circumferentially offset.
