Patent GB-1025716-A (GB)
Title: Method and apparatus for solvent extraction stripping
IPC: C22B3/02
Filed: 1963-12-17
Abstract: <PICT:1025716/C1/1> An aqueous insoluble material is stripped from an organic solvent by countercurrent flow in a vertical column (Fig. 3), loaded solvent being sprayed at 60 into the lower end of the column and overflowing at 42 from a floating layer of stripped solvent while an aqueous stripping solution is supplied to the upper end at 64 and is withdrawn at 54 together with precipitated solid material. A rake 70 directs solids to outlet 54 and heating/cooling coils 56 are supplied.  In an alternative embodiment (Fig. 2, not shown) the aqueous solution is sprayed into the floating layer of solvent, and the column has a heating/cooling jacket.  The process is applicable to extraction of vanadium, uranium, scandium, tungsten.  In Fig. 1 (not shown) metal salts are extracted (at A) from an aqueous feed liquor by an organic solvent which is then supplied through a heat exchanger 16 to the stripping column (B) (Fig. 2, not shown, and Fig. 3).  The stripping solution and precipitate are separated in a filter or centrifuge (C).  Various valves 18, 22 are controlled to ensure that the respective influx and eflux of both solvent and aqueous solution to and from the column (B) are equalized.  Heat exchanger 24 and an aqueous solution make-up line are shown.  In a particular example vanadium held as a solvent soluble complex with an agent such as tertiary amines, quaternary ammonium chloride (e.g. tricaprylyl methyl ammonium chloride) is extracted by an aqueous stripping solution. The solvent also contains 4% isodecanol. The aqueous stripping solution contains 200 gms./l. of ammonium chloride and sufficient free ammonia to produce a pH of 8.3 ... 8.5.  The temperature in the column (B) is held at 150 ... 160 DEG  F.

Title: Method for making bidirectional iron-aluminium alloy magnetic sheet
IPC: C21D8/12
Filed: 1963-12-31
Abstract: Bidirectionally orientated magnetic sheets are formed from an iron alloy containing 2-6% of aluminium and the balance iron incidental ingredients and impurities by a process comprising initially annealing a thick sheet of the alloy at a temperature above the primary recrystallisation temperature, generally above 700 DEG C., warm rolling the sheet at least once in the range 200-500 DEG C and finally annealing in the range 1050-1350 DEG C. Aluminium in the alloy can be replaced by silicon, the total content of aluminium and silicon being 2-6% and the aluminium content being at least 1%. Carbon may be present under 0.08% and sulphur under 0.05%.  In an example an alloy plate was annealed in wet hydrogen at 800 DEG C. for 30 minutes, cooled quickly to 300 DEG C., warm rolled twice at 300 DEG C. with an intermediate anneal at 1000 DEG C. in wet hydrogen, maintained at 500 DEG C. for several hours in dry hydrogen and finally annealed at 1100 DEG C. for four hours.

Abstract: 515,649. Cutting, embossing and moulding dough for' biscuits. CASARETTO. W., and CASARETTO, B., [trading as HENGLER & CRONEMEYER]. June 23, 1938, No. 18658. [Class 37 (ii)] A machine for embossing and cutting-cut dough for biscuits comprises a cutter 33 and embosser 36 mounted in a wheeled carriage 7 movable on an arcuate track 10 in a verticallyreciprocable carrier 9. The embossing and ejecting plate 36 is carried by a slide 39 movable in the carriage 7 and operated by a shaft 42 and eccentric 41. The shaft 42 is fixed to a lever bearing in a stationary track such that on raising the carrier 9 and carriage 7 the shaft 42 is rotated to move 'the ejector. Dough is sheeted by rolls 1 and conveyed by driven rollers 2 to an endless band 3 and thence to the cutter assembly 4 and a delivery band 5. Cutting and embossing are effected. by a rocking movement of the carriage 7 in the track 10 against a counter-pressure support 8. The carriage 7 and support 8 are moved, during cutting, at the same speed and in the same direction as the dough. After cutting, the carrier 9 is raised and causes the embosser 36 to eject the cut dough. The carriage is returned on the track at an accelerated speed. The cutter 33 is fixed to a beam 29 and clamps to it a plate 34 carrying pins 35. A hollow member 30 having a curved roller surface embraces the cutter 33 and is mounted on springs 32 so as to be slidable on the beam 29. The support 8, carriage 7 and carrier 9 are driven from cam discs on a drive shaft such that the support and carriage are moved first and the carrier is - vertically reciprocated after the cutting operation. The support 8 slides on a verticallyadjustable table. A rubber roller 46 may be substituted for the support 8. The driving mechanism is adjustably controlled from the speed of the oven band to which the dough is delivered. The machine can be converted into a rotary dough moulder by removing the carriage and cutter assembly from the track 10 and providing a .shaping roller 50, hopper 52 and fluted pressure roll 51, the dough shapes being transferred by the rubber roller 46 to the band 3. The waste dough strip is fed upwards by a lever 54, the dough shapes being delivered by the conveyer 5.
