[Also in Division G4] A counter constructed from photoconductive and electroluminescent devices is shown in Fig. 3. The counter is primed by closing switch S, whereupon a flash of light from lamp NI illuminates photoconductor 20 and electroluminescent device 21 is energized from terminals 18, device 21 creating a holding circuit for itself by illuminating a photoconductor 22. Device 21 also primes the first stage of the counter proper by illuminating photoconductor 24. A pulse applied to terminals 38 energizes an electroluminescent strip 19 which is common to all stages of the counter, and device 25 is then energized through a further photoconductor 40 associated with strip 19. Device 25 creates a holding circuit for itself through photoconductor 26, extinguishes device 21 by creating a shunt path through a photoconductor 23, and primes the next stage 29 by illuminating photoconductor 28. The following stages operate in a similar manner. The counter may be used to control a stepvoltage generator, Fig. 1, forming a balancing voltage source in an analogue-to-digital converter. The unknown voltage is applied at X, and devices 23, 25, 29 . . . of Fig. 3 are represented in Fig. 1 by light sources L 0 -L 9 . Initially L 0  is energized and photoconductor R 0  supplies a balancing voltage of 0.1 volts from a 1-volt source B 1 . Assuming an input at X of 0.86 volts, difference amplifier M energizes a lamp A1 which in turn controls a relaxation oscillator, Fig. 2 (not shown) supplying pulses to terminals 38, Fig. 3. Sources L 0 -L 8  are energized in sequence by the counter to produce an increasing step voltage until the input X is exceeded. Amplifier M then extinguishes A1 and lights A2, the latter controlling a further pulse source and counter including electroluminescent devices L 0 <SP>1</SP>-<SP>L</SP> 9 <SP>1</SP>. Devices L 9 <SP>1</SP>- L 6 1 are energized in turn to reduce the balancing voltage in steps of 0.01 volts until equality is attained.

Title: Improvements in or relating to the extraction of metals from aqueous solution
Inventor: KEMBER NORMAN FRANK
IPC: B01D15/08
Filed: 1955-12-22
Abstract: Dissolved thorium, uranium, zirconium or hafnium are removed from aqueous solutions which are at least N/10 with respect to mineral acid, by contacting with phosphorylated cellulose to effect absorption of the metal ions, which may therafter be recovered by treatment with an eluant which forms a water-soluble complex salt with the absorbed metal, or by heating the phosphorylated cellulose with a concentrated acid to degrade the cellulose.  The acid concentration is preferably at least normal or higher and the selectivity of absorption increases with increase in acid concentration.  The process may be effected in an apparatus such as is employed in chromatographic separation, that is, a column containing the phosphorylated cellulose is contacted with the liquor and is either treated in situ with an eluant to complex the absorbed metal, washed with water and then with acid to regenerate it, or alternatively the column may be sectioned after treatment to isolate that part of it containing the desired absorbed metal.  The invention is particularly applicable to solutions containing high phosphate concentration.  According to examples: (1) an aqueous thorium-containing solution 4N in sulphuric acid and containing iron, rare earths and a high phosphate content was passed through phosphorylated cellulose prepared from wood pulp which has been previously moistened with 2N sulphuric acid.  Iron and thorium were both adsorbed and the column was then washed free from acid with ammonia and treated with 2N aqueous ammonium carbonate to elute the thorium as a complex carbonate.  If the iron is previously reduced to the ferrous state it is not adsorbed.  (2) Aqueous N-sulphuric acid solution containing uranium and ferrous iron was contacted with phosphorylated cellulose whereby uranium with a minor amount of iron was adsorbed.  The uranium was eluted by 2N aqueous sodium carbonate solution.  (3) An aqueous N-sulphuric acid solution containing zirconium with hafnium impurity was passed through phosphorylated cellulose whereby both were adsorbed and subsequently eluted by 0.2N ammonium fluoride solution.  Copper, magnesium and aluminium are adsorbed only to a slight extent.
