[Also in Division G6] Uranium is separated from irradiated thoriumcontaining nuclear fuel by (a) chlorinating the comminuted fuel at 900-1200 C.; (b) separating a uranium-containing fraction and a thoriumcontaining fraction from the volatile chlorides; (c) forming an aqueous solution of the separated uranium-containing fraction; and (d) extracting uranium from the aqueous solution with an organic phase containing a tertiary amine. The fuel treated may be thorium and uranium oxides or carbides coated with or dispersed in graphite, pyrolytic carbon, or silicon carbide. ' The uranium may be present as U235 or bred U233. Chlorination may take place in a fluidized bed using chlorine, phosgene, or carbon tetrachloride, or mixtures thereof, and the volatile chloride mixture may be passed into a fluidized quartz sand bed at 400-500 C. in order to condense thorium chloride and some fission product chlorides. The remaining chloride vapours may be cooled to 0-20 C. to condense uranium chloride and other fission products or may be treated with oxygen or steam at 380- 450 C, to form uranyl chloride or uranium oxide. The separated uranium compound is dissolved in water or hydrochloric acid, oxidized with chlorine, and passed through a column of silica gel or high silica glass to remove protactinium which may be eluted from the column with oxalic acid solution. For extracting uranium from the aqueous solution, a solution of  straight chain alkyl tertiary amines in solvent naphtha is used. The extract is washed with a solution of magnesium chloride to remove fission products and the uranium re-extracted with distilled water. 1,226,723.Stabilized ammonium nitrate.

Abstract: 1290143 Digital transmission systems WESTINGHOUSE BRAKE & SIGNAL CO Ltd 22 Oct 1969 [23 Oct 1968] 50222/68 Heading H4P  Binary data is transmitted by frequency shift. Each word is separated from the next by a third frequency. A free-running clock is synchronized by a signal derived from the data words.  Transmitter, Fig. 2 (not shown).-An 18-bit parallel bit data word is read in to a shift register (5) under the control of a pulse from a clock source (1, 2) at the start of a clock cycle. During clock pulse periods t0-t2 a frequency f3 is transmitted. During t3-t21 the word is read from the register and transmitted as frequencies f1 and f2. During t21-t23. f3 is again transmitted.  Receiver, Fig. 4 (not shown).-The received signal a passes to a demodulator (12) which presents signals b; c on mark and space leads. The signal b is passed to a shift register (19). Signals b and c pass to an OR gate (13) which outputs d, the latter passing to an AND gate (17) and also to a monostable (14) which outputs e. Pulses e reset a cyclic counter (15) fed by clock pulses at 8 times the bit rate. The counter gives a pulse whenever it reaches a count of 2 and feeds the AND gate ( 17) which consequently gives an output f which controls read-in of the data to the register (19). Pulses f also feed a second counter (18) which is reset when the first counter (15) reaches a count of 7 in the absence of signal d. This condition occurs at the end of a data word. The pulse from the second counter (18) may initiate a parity check.
