Title: Process for the production of pure metal chlorides
IPC: C01B33/08
Filed: 1965-12-23
Abstract: 1,127,079. Recovery of metals from oxidic ores &c. HALOMET A.G. 23 Dec., 1965 [31 Dec., 1964], No. 54608/65. Heading C1A. Pure metal chlorides are produced by reacting an oxidic material with chlorine in a countercurrent process, and adding carbon downstream of the ore, the amount of C1 2  being stoichiometrically proportional to the amount of the metal in the ore with the greatest chloride forming affinity. The process is repeated for each metal present. Alternatively, the amount of C1 2  may correspond to the total amount of all metals present having a Cl affinity greater than that of a particular metal; a second chlorination then yields the required chloride. Cl affinities are given at 1300 and 800 C. Reaction temps. from 400 to 1150 C. are exemplified. The carbon may be coal, peat or petroleum coke, or wood charcoal. The oxidic material may be an ore, clay or slag. Cold inert solids, e.g. residues from the process, may be mixed with the ore to control temperature. Chlorides of Fe, Ti, Al, Si, Sn and Zn may be thus obtained. The residue, containing chlorides of Mn, Ni, Cr, Co, Na, K, Mg, Ca and Ba, may be treated with water or aqu. HCl; metal hydroxides are pptd. with NaOH or KOH; then alkaline earth carbonates are pptd. with CO 2  (e.g. waste gas of process); finally the alkali metal chloride soln. is electrolysed to give hydroxide and C1 2 , both being reused. The product gas may be purified with activated carbon, SiO 2  gel, or molecular sieves; then, after condensation of the metal chlorides HC1 is recovered by washing with water, and may be used to treat the residue, or may be electrolysed to give C1 2  for reuse; V and P are then recovered by adding water or steam at 110-140 C. to give H 3 PO 4  and V 2 O 5  mist which is absorbed in hot H 3 PO 4  and the solid V 2 O 5  separated. The metal chlorides produced may be oxidized to oxides and the liberated C1 2  reused, or may be reduced or electrolysed to metals.

Title: Radix Conversion Circuits
IPC: H03M7/12
Filed: 1966-12-12
Abstract: 1,167,528. Radix converters. INTERNATIONAL BUSINESS MACHINES CORP. 12 Dec., 1966 [30 Dec., 1965], No. 55459/66. Heading G4A. A radix converter with means for selecting the target radix gates the input number to an arithmetic circuit under the control of the selecting means to generate a sum representing the units digit of the output number, the difference of the input number and this sum being used in a similar way to obtain the next output digit, and so on. The conversion algorithm is applicable to any initial radix C and final radix m which satisfy for some non-negative integers n and P, and parameters for a number of possible cases are listed in the Specification, but two embodiments described in detail are as follows. In the first embodiment, binary data can be converted to binary-coded decimal or binarycoded radix 12 form, using most of the equipment in common for the two cases. The bits of the binary input are read from memory in turn, low order first, and each used to pass the units digit of the output radix equivalent of the bit, in 8-4-2-1 parallel form to an accumulator for addition without carry to the sum of such units digits derived from the previous bits of the binary input, this sum being temporarily stored in four latches. The final result in these latches, being the units digit of the output radix equivalent of the input binary number, is now subtracted from the input binary number by feeding both together, serially-by-bit, low order first, to the accumulator which is now operating as a subtractor with a borrow feed-back via a one-bit delay. The serial-by-bit accumulator output is placed in the memory and then divided by the output radix 10 or 12. This is done by a one-bit shift followed by a division by 5 using subtraction in the case of radix 10, and a two-bit shift followed by a division by 3 using subtraction in the case of radix 12. The shift is done by reading from memory high order first, and back into memory via a suitable delay, and the subtractive division is done (reading from memory low order first) using the accumulator with serial-by-bit inputs and outputs, a borrow output of the accumulator being fed back to the input via a one-bit delay and the accumulator result output, besides being stored in the memory, being fed to the accumulator input via a one or two-bit delay (for the divide by 3 and 5 cases respectively). The division result is used to obtain the next output digit in the same way, and so on. In the second embodiment, binary-coded ternary data can be converted to selectively binary-coded decimal or binary-coded radix 12 form. This embodiment is similar to the first except that the accumulator inputs and outputs are weighted 6-3-2-1 rather than 8-4-2-1, ternary digits are always transferred parallel-by-bit, the shifts are 1 and 0 positions for output radices 12 and 10 respectively and the following subtractive divisions are therefore by 4 and 10 respectively. Pence in binary-coded-form may be converted to pounds, shillings and pence using two conversions, from base 2 to base 12, then base 12 to base 20.

A process for recovering hydrazine from an aqueous solution thereof comprises fractionating an aqueous ketazine solution in a tray or plate column 1, hydrazine being obtained by hydrolysis of the enriched distillate, wherein theliquid phase is removed from a tray or plate 2 in the lower third of the column and is mixed with fresh ketone in a pressure vessel 12 without intermediate cooling in a quantity of from 1 to 20% of the ketone present in the starting solution and wherein after a residence time of at least 15 minutes the liquid mixture is returned to the column at a tray or plate beneath that from which liquid phase is removed. Vapour produced on leaving the pressure vessel 12 passes through a pipe 15 to join the enriched vapours from the column. Liquid substantially hydrazine- and ketone-free is removed at 4.

The disc is held in locked position by bending the disc and engaging bosses 24 on the underside of the disc in recesses 25 in the housing bottom rims (26) on the housing bottom snapping into notches (27) in the underside of the disc. Tongue 21 is guided during vertical movement in channel 20 and in the locked position portions of the disc adjacent the tongue 21 are wedged in notches 23 in adjacent lugs 10. An inflation nozzle 18 with a peripheral rim 19 is removably retained in the housing with the rim 19 received in groove 17. A lid (16) is screwed on to the housing after the nozzle has been removed. In modifications the tongue is forked and engages around a shouldered lug or below a spring-loaded piston and the tongue is rotatable below a shoulder on a lug or a spring-loaded piston. Alternatively the underside of the disc carries a plate which can be passed through a complementary opening in the housing bottom and turned to lock the valve open. The plate may be replaced by a spike which is snap-fitted into a hole defined by resilient tongues in the housing bottom or by resilient tongues which are engageable in a hole in the housing bottom.

Abstract: 1,142,896. Reflectors. OLDHAM & SONS Ltd. 22 Nov., 1967 [19 Dec., 1966], No. 56795/66. Heading F4R. A reflector, especially for a miner's cap lamp, is coated on the reflecting surface with a diffusing coating of semi-opaque varnish. The varnish is preferably a mixture of a matting agent such as diatomaceous silica dispersed in a synthetic resin in organic solvents and a clear varnish which may consist of synthetic resins in organic solvents. The coating may be applied by spraying with a gun connected to a continuous circuit so that the varnish is circulated to and from a reservoir, thereby ensuring thorough mixing. After spraying, the coating is allowed to settle and is then stoved in an oven. The reflecting surface may be produced by, for example, the vacuum deposition of aluminium.
