Abstract: 1,052,469. Concentrated ammonium nitrate. CHEMICAL CONSTRUCTION CORPORATION. Dec. 8, 1964 [Dec. 13, 1963], No. 49980/64. Heading C1A. Concentrated ammonium nitrate solution and process steam are produced by reacting aqueous nitric acid with ammonia vapour, cooling the reaction mixture by heat exchange with dilute NH 4 NO 3  solution, which is thereby concentrated, further cooling by heat exchange with liquid water which is vaporized to steam and returning the resulting cooled dilute NH 4 NO 3  solution to heat exchange with the reaction mixture. Nitric acid from 1 is preheated by steam to 150‹ F. to 250‹ F. and passed into Venturi mixer 6. The HNO 3  in excess is diluted in 6 with recycled NH 4 NO 3  solution from 7, passed into a manifold 9 and split into a plurality of streams 10, 11, 12, entering 13 to react with ammonia entering at 14. Alternatively the ammonia feed stream may be split up into separate streams and may be urea off gas or derived from aqueous or liquid ammonia. The reaction in 13 is at 275‹ F. to 350‹ F. and 10 to 100 p.s.i.g. and baffles 17 improve heat exchange. The reaction mixture passes to cooler at 18, round baffles 23, and leaves at 24 at 250-300‹ F. after steam condensation. Water entering at 21 is converted in 19 to steam at 10 to 30 p.s.i.g. withdrawn at 22. The cooled stream is passed from 24 into gas-liquid separator 25 whence 70% NH 4 NO 3  solution is recycled at 15 to heat exchange in tubes 16 in reactor 13. Concentrated, e.g. at least 80%, NH 4 NO 3  solution is separated from steam at 5-20 p.s.i.g. in separator 28 and recovered at 29, part for recycling to mixer 6 and part for product after neutralization of excess acid with NH 3  at 31. The steam from 28 passes to preheater 2 and an ammonia preheater may also be provided. The NH 4 NO 8  solution may be further concentrated by countercurrent passage to air at 60-190‹ F. through a steam jacketed vessel to 95%. Steam may be used in urea synthesis process to concentrate aqueous urea solution.

Abstract: 1,228,152. Speech recognition. ELECTRIC & MUSICAL INDUSTRIES Ltd. 10 May, 1968 [17 Feb., 1967], No. 7568/67. Heading G4R. Speech analysing apparatus produces a signal indicative of the interval of time from a voicing instant to a subsequent zero crossing of an oscillation of the input signal below a particular frequency after at least one cycle of the oscillation has occurred and before the next voicing instant, and includes means utilizing an indicative signal to obtain the most likely identity of a phoneme. A speech waveform from microphone 10, after amplification with automatic gain control at 12, 13 is split into frequency ranges by filters 15, 16, 17 (below 700 c/s., between 700 and 2100, and above 2100 respectively). Detection of a voicing instant at 29 permits ring counter 30 to be driven by 9 kc/s. oscillator 31. Outputs 6-10 of counter 30, which occur non-linearly due to feedback to the oscillator 31, are applied to vowel selector 24 and the one present at the second negative-going zerocrossing (after the voicing instant) in the output of filter 15 is passed to decoder 27 to identify a vowel, this zero-crossing being detected by A and A<SP>1</SP> counters 18, 19 driven by the output of filter 15. During the first voicing period, the A counter counts up, and during the second it counts down and the A<SP>1</SP> counter counts up, and so on, so that the difference in the numbers of cycles in successive voicing periods is indicated and if this is zero a signal TA is produced. The time this signal lasts is measured by TA counter 38 (driven by oscillator 33) and supplied to decoder 27. A digitization of a logarithmic representation of the speech waveform amplitude is provided to decoder 27 by G quantizer 14, and a voiced/unvoiced indication is provided by voicing detector 20. Each of B and C quantizers 25, 26 converts its input to a D.C. level using a diode pump discriminator and digitizes this by comparing it with a ramp produced under control of outputs 2-5 of counter 30, equality gating the currently active output to decoder 27. Decoder 27 also receives digitizations of the time durations the following conditions are satisfied, from TC, TG, TN counters 39, 40, 41, respectively: (a) the output of the C quantizer is relatively high (fricative consonants), (b) the G quantizer indicates low amplitude and the high frequency component is of low level (silence or just before a stop consonant), (c) fifth output of vowel selector 24 is active (i.e. longest duration between zerocrossings) and the amplitude is not high (G quantizer 14) and there is no high frequency component (C quantizer 26) and not unvoiced (nasal consonants). Recognition of a phoneme by decoder 27 actuates phonetic typewriter 46 or a computer, and resets the system for recognition of the next phoneme.

After threading, pressure rollers 38, 48 move to the positions 42, 52 leaving free loops, while tensioning rollers 32, 60 are moved to positions shown in broken lines. Film is intermittently fed through gate 20 by sprocket 44. The projector has a fail-safe system whereby projection cannot begin until threading is completed correctly. Movement of arms 40, 50 carrying rollers 38, 48 to the operating position is sensed by switches 80, 84, while switch 82 senses film pressed against curved gate guides 70 by strips 76 in the operating position. Arms 62, 64 are moved by lever 68 to press film 16 round sound head 18, the movement of arm 62 being sensed by switch 78. Film tensioning. Tensioning arms 30, 58 are each mounted on a shaft such as 87, Fig.2, and are spring-urged to the operative position. A potentiometer 104 geared to shaft 86 senses the angular position of arm 30 and supplies a signal controlling the supply reel motor, or the take-up reel motor in the case of arm 58.
