Abstract: 916,157. Automatic character reading. STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTIJEN, TELEGRAFIE EN TELEFONIE. Dec. 5, 1960 [Dec. 8, 1959], No. 41739/60. Class 106 (1). Characters having timing marks in a horizontal line underneath as described in Specification 912,075, are read by being moved horizontally past three reading elements adapted to sense respectively the upper and lower halves of the character and the timing marks, the arrangement being such that the signals derived from sensing the character represent the character in a code that can be tested for validity. According to the invention there are a number of sets of reading elements interleaved one above the other, the output of each set being tested for validity and the valid one accepted. In Fig. 2 there are three sets of reading elements I, II, III; I<SP>1</SP> ,  II<SP>1</SP>, III<SP>1</SP> and I<SP>11</SP>, II<SP>11</SP>, III<SP>11</SP>. In the first set element III senses the timing marks and produces gating signals which are applied to gates P1, P2 to sample the outputs of elements I and II at the proper times. The timing pulses are also applied to a distributer 3VV which gates the character signals from gates P1 and P2 into six storage units A-F. The circuit K tests the six output lines for a valid combination and if one is present it enables gate P10 so that if the distributer indicated that the third timing mark has been passed an enabling pulse is passed to gates P11-P16 to apply the signals to terminals U1-U6. The other two sets are similar, the signals being applied to terminals U1-U6 if a valid combination is present. The read out pulses from any of gates P10, P<SP>1</SP>10 or P<SP>11</SP>10 are passed to a pulse shaper H1 which resets the storage units ready for the next character.

Title: Low temperature gas separation
IPC: C10K1/00
Filed: 1964-10-19
Abstract: 1,017,660. Electrostatic separators. CONCH INTERNATIONAL METHANE Ltd. Oct. 19, 1964 [Jan. 8, 1964], No. 42564/64. Heading B2J. A mixture comprising two different gases, one of which solidifies at a higher temperature than the other, is separated into its constituents by cooling the mixture until a slurry is produced in which one of the constituents is in a liquid phase and the other in a solid phase, charging the solid phase particles with a charge of single polarity and separating them from the liquid by attracting them to an electrode of opposite polarity. In Fig. 1, a liquid mixture of methane and carbon dioxide produced in a liquefaction plant 2 is is cooled by passing through a throttle or expansion engine 4 to produce a mixture containing a liquid phase of methane, a vapour phase of methane and a solid phase of carbon dioxide. The throttling or expansion step produces a high degree of turbulence so that the solid CO 2  particles become electrically charged with a charge of negative polarity. This is enhanced by earthing the pipeline 3, 6 at 5 so that the liquid becomes statically charged through friction in the pipeline, the charge becoming associated with the CO 2  particles as they are formed. The vapour-liquid-solid mixture is then passed through a separator 7 from which the vapour is discharged at 8 and a slurry of charged solid CO 2  particles in liquid methane is conveyed via a pipe 9 to an electostatic separator 11. The latter consists of a drum 17 rotating in a chamber 12, Figs. 3 and 4 (not shown), the surfaces of the drum and of the chamber wall being electrically conducting and respectively connected to the positive and negative terminals of a D.C. generator 14. As the slurry enters between the drum and the chamber wall, the CO 2  particles are attracted by the drum and subsequently removed therefrom by a stationary scraper 22 to be conveyed away while the clear liquid methane is discharged via an overflow 23. Instead of cooling the liquid mixture in line 3 by expansion or throttling it can be cooled down by external refrigerating means to a mixture of liquid methane and solid CO 2  particles without vapour present. In this case, in order to enhance the frictional charging effect, earthed screens are supported within the pipeline and, since vapour is absent, the separator 7 is dispensed with. Other applications of the process include the separation of CO 2  from liquid air or liquid N 2  and H 2 S from methane.

Abstract: 1,237,136. Phase comparators. HONEYWELL Inc. 16 Sept., 1968 [2 Oct., 1967], No. 43978/68. Heading H3A. [Also in Division G3] In a synchronizing system in which a signal 23 phase-modulated in dependence on the magnitude of a variable, e.g. pitch attitude, is compared in phase with a reference signal 22 of the same frequency so that any difference is, in one mode (synchronization mode) automatically corrected by advancing or retarding a counter 10 from which the reference signal is derived, and in the other mode (hold mode) is used to provide a control signal 25, a trigger 30 which provides the advance or retard signals for the counter 10 during the synchronize mode is triggered only when the output of an integrator 26 reaches a predetermined positive or negative value to ensure that during the changeover from the synchronization mode to the hold mode, the synchronizer does not lock on to phase errors in the input signal 23. The trigger 30 has three output terminals 32, 34, 35 which apply various combinations of binary signals to logic circuitry controlling twelve-stage counter F-F1 ... F-F12 to cause it to skip a pulse, advance a pulse, or count the clock pulses 44 normally, depending on whether the reference signal 22 is leading, lagging or in phase with input signal 23. When trigger 30 triggers it provides a reset pulse 31 to integrator 26. Integrator will continue to integrate and switch trigger 30 until the signals 22 and 23 are in phase. The error detector 21 is fed from the last two stages of twelve-stage binary counter 10 and the input terminal 23. When at least one of the three input signals to terminals 20, 22, 23 is a "0" (i.e. ground or negative) junction 54, Fig. 3, is held at a low potential so that transistor 57 and consequently transistor 67 will be biased off. At least one of the three input signals will be a "1" (positive) so that both transistors 83 and 91 will be off. With no phase difference between inputs 22 and 23 no output signal will be produced at 24. If input 22 lags 23 by less than 90 degrees at least one of the signals is always positive (Fig. 4B, not shown), so that transistors 83 and 91 are always off. However, there is a short time when all three pulses are coincidentally positive, during which time transistors 57 and 67 will be switched on to provide a D.C. output at 24. If the phase of input 22 lags 23 by more than 90 degrees, the transistor 67 will be switched on as before, but will remain on for the same length of time in each cycle. There will also be a short time when the inputs 20, 22, 23 are coincidentally "0", during which time transistors 83 and 93 will be switched on so that a negative pulse of magnitude equal to the phase difference will be applied to terminal 24. Thus the error signal at terminal 24 rises linearly to a maximum at 90 degrees phase lag and decreases linearly to zero at 180 degrees phase lag. Similar action occurs if input 22 leads input 23.
