Title: Process for the preparation of ammonium fluoride
IPC: C01C1/16
Filed: 1955-12-01
Abstract: Phosphate-contaminated silicon tetrafluoride-containing gases are absorbed in water, or water containing ammonia, the resulting solution is reacted with ammonia under conditions to maintain a pH not exceeding 9 until substantially complete hydrolysis of the fluosilicates is effected, precipitated silica is separated, the solid-free liquor is reacted with ammonia under conditions to maintain a free NH3 concentration greater than 1 per cent to precipitate ammonium phosphate, and the ammonium phosphate and ammonium fluoride are separately recovered. Den gases containing HF and SiF4 from the reaction of sulphuric acid and rock phosphate are absorbed in water containing sufficient NH3 to maintain the pH 3.5-5.5. The resulting solution and anhydrous NH3 are added to ammonium fluoride solution containing free ammonia with agitation to adjust the pH to 8-9 and precipitated silica is filtered off. Anhydrous ammonia is added to above 10 per cent free content by charging the solution into a closed vessel containing an atmosphere of ammonia at 5-50 lbs./sq. in. Preferably the solution is saturated with NH3 at a partial pressure of 1 atmosphere at 22 DEG C. Precipitated triammonium phosphate is filtered off and the filtrate is concentrated to recover ammonium fluoride or bifluoride.

Title: Subhalide distillation of aluminum
IPC: C01F7/62
Filed: 1960-11-11
Abstract: <PICT:0947227/C3/1> Thermally unstable gaseous compounds of aluminium, such as sub-halides, are decomposed by passage along a path defined by surfaces of graphite having an apparent specific gravity of greater than 1.5, the graphite being cooled at such a rate as to maintain its surface temperature between about 1200 DEG C. and 660 DEG C. Cooling may be effected by allowing heat to radiate from the graphite to a surrounding thermally conductive body spaced therefrom, said body being cooled if necessary by liquid coolant. Excessive cooling at the outlet end of the condenser may be avoided by interposing thermal shielding between the graphite and the outer body. In the form illustrated, the graphite forms a column of trays 44 and 45, each having a perforated bottom plate, the holes in alternate plates being offset, and the column is closed by cover 49, and by well 50.

Title: Fluid engaged clutch modulated by transmission ratio
IPC: B60W30/18
Filed: 1967-04-06
Abstract: The fluid apply pressure of a pedal controlled, e.g. hydraulically applied, clutch at the output side of a variable-speed gear in a motor vehicle, e.g. a tractor, is varied in proportion to the numerical gear ratio (i.e. input to output speed ratio), of the variable-speed gear. As shown, a governed-speed engine 10 drives an infinitelyvariable expanding pulley gear 12 which drives a forward/reverse planetary gear 14, the carrier 44 of which may be clutched to the sun gear 38 by clutch 46 for forward, or braked (not further described), to the casing 50 for reverse. Clutch 46 apply pressure is supplied by a pump P, and modulated by a valve 52 which vents hydraulic pressure between clutch apply line 59 and sump 60. The valve spool 62 is urged to the right by clutch apply pressure fed to the end 72 of the valve via bore 70, and to the left by a compression spring 82 acting between the spool end and a rod 78 connected to the clutch pedal 80, and by feedback pressure 104 in line 102 which includes a restricted orifice 106, the pressure 104 being controlled by a variableorifice valve 88. The spool 96 of valve 88 is positioned by gear lever 32 controlling the gear 12, to vary the orifice 98 and hence vent feedback pressure to sump 94, upshifting the gear increasing the size of orifice 98 to decrease the feedback pressure, and hence lower the clutch apply pressure. Again, Fig. 2 (not shown), clutch apply pressure is vented by variable orifice valve (88a) to a sump directly from the end (72a) of valve (52a), bore (70a) being formed with a restricted orifice (105). The expanding pulley gear may be replaced by a steppedratio gear.

Title: Process for treating residual liquors from the manufacture of phthalic anhydride and the recovery of citraconic and maleic anhydrides and acids therefrom
IPC: C07C51/43
Filed: 1967-06-13
Abstract: Citraconic anhydride is obtained by separating at least part of the maleic acid present in an aqueous solution obtained as by-product during the manufacture of phthalic anhydride and heating the resulting solution with a solvent having a boiling point of not more than 140 C., whereby the solution is dehydrated and the citraconic acid present is converted to citraconic anhydride which dissolves in said solvent, separating the residue from the resulting solution and evaporating the solvent. The preliminary separation of the maleic acid may be effected by concentrating the initial aqueous solution whereby maleic acid crystallizes out and is separated from the solution, by converting it to fumaric acid and separating the fumaric acid from the aqueous solution, or by partially neutralizing the initial aqueous solution so that the maleic acid present is converted to an acid metal maleate, which is separated off, and then acidifying this solution. The citraconic anhydride and maleic acid thus obtained may be converted, into citraconic acid and maleic anhydride respectively.

Title: Separating magnetic particles from liquid slurries - having pre-treatment in magnetic field to cause agglomeration of fine particles
IPC: B03C1/025
Filed: 1976-04-15
Abstract: Process for altering the relative size of particles with different magnetic susceptibilities which are together in a liquid slurry involves passing the slurry through a magnetic field of sufficient strength and for a long enough time to cause individual particles of the more magnetic material to agglomerate. This is done prior to feeding through a separator containing a magnetisable packing (e.g. wire mesh) in a magnetic field which retains the magnetic particles. A flocculating agent is added to the slurry before it is processed. The agglomerate particles have a size 10 mu m. The magnetic ones have a susceptibility of between 10-5 and 10-3 (in S.I. units). A field strength between 1 and 10 Teslar is used with a residence time of longer than 2 sec. For use in separation systems where magnetisable material (esp. ferrous material) is separated from particulate slurries. If the ferrous material is very finely divided, then separation is poor esp. where the non-magnetic particles are larger than the magnetic ones. The system described improves thsi separation by causing agglomeration of the magnetic particles.
