Title: Method of treating crude gas liquor to obtain ammonia solution
IPC: C01C1/10
Filed: 1920-07-07
Abstract: 147,099. Still, C. [Firm of]. Dec. 6, 1915, [Convention date]. Ammonia, distilling.-In treating ammoniacal gas liquor to obtain ammonia solutions, the liquor is passed down a column a, and is divided at the base into two streams, one of which passes down a column b to a liming-vessel d while the other passes by a pipe i directly to the liming-vessel. The liquor passes from the vessel d down a column c. Steam is injected into the base of the column c and of the vessel d and the vapours therefrom pass up the column b and drive off carbon dioxide from the liquor. The mixture of steam ammonia and carbon dioxide is in part withdrawn by a pipe s to a condenser and in part passes up the column a and expels carbon dioxide, which passes from the upper part free from ammonia. The amount of carbon dioxide which passes with the ammonia bv the pipe s is regulated to prevent disturbance in the condenser by formation of ammonium carbonate by adjusting the amount cf liquor which passes down the pipe i, and sufficient lime is added by pipe k to combine with the carbonic acid which remains in the liquor and to liberate the ammonia. Part of the vapours from the column c may be passed directly to the pipe s by a pipe t.
Patent GB-1503806-A (GB)
Title: Defect detection and compensation system
IPC: H04N5/76
Filed: 1975-05-07
Abstract: 1503806 Drop out compensation RCA CORPORATION 7 May 1975 [6 June 1974] 19162/75 Heading H4F A video record playback system provides dropout compensation by detecting when the frequency of the carrier falls outside a predetermined range, and in that time substituting a delayed video signal. As described the video signal is demodulated by zero-crossing detector 15 and low pass filter 17 and is normally supplied via switch 21 to processing circuitry 23 and receiver 25. The frequency of the video carrier is indicated by the amplitude of a signal produced by filter 31, and comparators 33, 35 produce defect indication pulses when said amplitude lies respectively above or below predetermined thresholds. A control circuit 40 controls switch 21 to supply to the signal processing circuit either the undelayed video signal, or during a drop out, the video signal corresponding to the previous line as developed in circuit 50. Since filter 17 has a slower response time than filter 31, the defect indication pulses will terminate before the end of the drop out in filter 17 which would result in the undelayed video signal being switched in before the end of the drop-out. To prevent this, retriggerable one shot 41 provides a pulse long enough to lengthen the defect indication pulses to compensate for the slow response of filter 17. In the event of a series of defect pulses separated by less than the period of the one shot, mixer 43 produces a single long defect indication signal, and switch S supplies the delayed signal for the whole period of the drop outs. In the event of a single, long defect indication pulse, no lengthening occurs. As an alternative to the retriggerable one-shot, the defect pulses may be passed through an envelope detector comprising a diode and capacitor wherein the discharge time of the latter is chosen to sufficiently lengthen the defect pulses. Furthermore duplication of FM detectors (15, 17 and 55, 57) may be avoided by providing a 1 delay in the processing circuit from which the output is fed back to switch 21. The invention may be applied to the playback of video discs or any other form of video record.

Abstract: 853,162. Arc-rupturing in switches. TELEMECANIQUE ELECTRIQUE. June 16, 1958 [July 3, 1957], No. 19255/58. Class 38 (5). In a switch in which a pair of opposed flat contacts 1a, 2a separate in a direction generally normal to their plane of contact, an angled magnetic member 5 is arranged adjacent to them, causing the arc to deflect towards and be quenched on the flange parallel to conductors 1, 2. The contacts may have the same width as the conductors (Fig. 3, not shown), but the quenching effect can be assisted by displacing them towards this flange, their near edges protruding beyond conductors 1, 2, if desired (Fig. 5a) and their far edges being bevelled at 6. The bridging contact arrangement of Fig. 6 has its contacts and flanges oppositely disposed to allow rotation of member 9 through 180 degrees, but the contacts and flanges may alternatively be disposed on the same sides of conductors 11, 12 (Fig. 6a, not shown).

In a time division multiplex switching system which normally caters for signals, such as speech, a limited frequency range (0-4 kc/s.), provision is made also for switching signals having a larger frequency range (0-12 kc/s.), e.g. data signals. The latter signals require sampling a three times the rate of the former. As shown, ordinary speech connections between subscribers such as 1TS1, 2TS1 are established by the resonant transfer method via gates 1GA, 1G, 2GA and 24-channel highways H1, H2, the gates being pulsed by pulses of a repetition frequency of 12À5 kc/s. at a phase allotted by the marker M and stored in timing stores 1PSM1, 5PSM1, 2PSM1. High-frequency range subscribers 1DS1, 2DS1 are provided with three transfer gates such as 1GC ... 1GE and three auxiliary gates such as A1GC ... A1GE interconnected via auxiliary storage condensers such as 1C1 ... 1C3. The auxiliary gates are pulsed in succession at three equally spaced time positions 1, 9, 17 in the cycle, these pulses occurring in the gaps between pairs of channel pulses. The results of these samplings are stored by the resonant transfer method or condensers 1C1 ... 1C3. Any three different free-channel positions may be selected by the marker and stored in storage means 1PSM3 ... 1PSM5, 2PSM3 ... 2PSM5 respectively and in 5PSM1, whereby resonant transfer may take place between 1C1 and 2C1; 1C2 and 2C2; 1C3 and 2C3. During the next positions 1, 9, 13 transfer takes place between 2C1, 2C2, 2C3 and the condenser associated with the circuit 2DS1. The arrangement can clearly operate in both directions. Similar arrangements are used for connecting a subscriber to a register.
