Patent GB-662391-A (GB)
Title: Electrical amplifier and receiver system
IPC: H03D1/16
Filed: 1949-08-26
Abstract: 662,391. Pulse modulation and valve receiving circuits. STANDARD TELEPHONES & CABLES, Ltd. Aug. 26, 1949 [Oct. 22, 1948], No. 22204/49. Classes 40 (v) and 40 (vi). A single device, which may be a thermionic valve or crystal triode, is arranged to perform repeatedly a first function on a portion of an electrical wave, means controlled by the passage of the wave conditioning the device to perform a second function on the wave portion. An amplitude or pulse modulated carrier wave received on aerial 1 is fed over tuned circuits 4, 6 to the grid of valve 10. Due to the back coupling from the anode over tuned circuit 20 the valve 10 is caused to oscillate at a frequency which is adjusted to develop a pulse of intermediate frequency in the anode circuit, the valve being blocked by rise in cathode potential to prevent continued oscillation. This pulse is fed to the circuit 23 tuned to the I.F., and thus over the delay circuit 24 to the grid of the valve. The process is repeated until the rise in potential occurring across the cathode resistor 16 is sufficient to cause the valve to operate as a demodulator. The resulting audio pulse appearing at the anode is fed back over lowfrequency transformer 26 to the grid of the valve. When the audio pulse is of sufficient magnitude, gas valve 28 fires to transmit an output pulse and reset the bias on valve 10 in readiness for the reception of the next R.F. pulse. In a modification, Fig. 3 (not shown), the screen and suppressor grids of a pentode are connected as a blocking oscillator to generate a frequency to beat with the R.F. to generate the I.F. for further amplification. An R.F. amplifier may be employed, Fig. 4, the output being fed over the delay circuit 24 to the grid of valve 56. The process is repeated until the bias built upon resistor 16 is sufficient for the valve to demodulate the signal. The valve then operates as an audio amplifier until the pulse occurring across the anode load 61 is sufficient to fire gas valve 28 to produce the output pulse. Specification 642,146 is referred to.

Patent GB-733796-A (GB)
Title: Method of working up aqueous liquors containing phenols, hydrogen sulphide, carbon dioxide, ammonia, and possible other organic or inorganic substances
IPC: C02F1/26
Filed: 1952-09-05
Abstract: <PICT:0733796/III/1> Aqueous liquors containing phenols, ammonia, carbon dioxide, hydrogen sulphide and possibly other organic or inorganic substances are worked up in a process in which the phenols are first recovered from the liquors by extraction with oxygen-containing organic solvents which are insoluble or only slightly soluble in water and which have a lower boiling point than the phenols and from the thus treated liquor the residual solvent together with the free ammonia, carbon dioxide and hydrogen sulphide are stripped out, the ammonia being recovered from the gases and vapours driven off, preferably as ammonium sulphate, and the bulk of residual organic solvent by condensation.  Suitable solvents are butyl acetate, isopropyl acetate, methylethyl ketone, isopropyl ether and other suitable ethers, esters and alcohols.  Fixed ammonia may also be recovered from the liquors by adding milk of lime.  As shown in Fig. 1 dephenolized liquor after treatment with a solvent for the phenols is fed by a pipe 2 into a direct condensing column 4 where it is used to condense solvent vapours and absorb NH3 from the gases and vapours fed into the column from a deacidifier 10.  At the bottom of the column 4 condensed solvent is led off at 141 and the liquor at a temperature of 40-70 DEG  C., for example 50 DEG  C., passes to the deacidifier 10 via a heat exchanger 6, and a direct steam heater 8 where the temperature of the liquor is raised to 90 DEG  C.  Steam is admitted to deacidifier 10 by line 11 and the H2S,CO2, solvent residues and some NH3 pass out of the deacidifier into the column 4 by line 12.  The gases leaving the column 4 chiefly CO2 and H2S and a little solvent vapour are washed, e.g. by phenol-containing liquor, to recover the last traces of the solvent and the H2S may be burnt to SO2 and converted to H2SO4.  Deacidified dephenolized liquor passes to a still 19 and is stripped of its free ammonia by steam admitted by line 20.  Hot effluent from the still 19 passes through the heat exchanger 6 and the vapours from the still are led into a saturator 22 containing H2SO4.  Ammonium sulphate is recovered from the saturator and steam and a little CO2 and H2S is led off from the saturator via line 25 and used either in the still 19 or deacidifier 10.  Some of the steam may be discarded through line 28 to prevent an excess of CO2 in the system.  If the fixed ammonia is also to be recovered milk of lime is added to the lower part of the still 19 or milk of lime is added to the liquor from the still 19 in a separate still.  In a modification the deacidifier 10 is omitted and the H2S, CO2, solvent residues and at least the free ammonia are stripped from the dephenolized liquor in a still, the vapours being passed to a saturator containing H2SO4 for direct absorption of the NH3, the unabsorbed gases then passing to a direct condenser for recovery of the solvent residues.

Abstract: 1,028,310. Transistor pulse circuits. LEEDS & NORTHRUP CO. June 1, 1964 [July 1, 1963], No. 22602/64. Heading H3T. [Also in Division G1] A photo-electric pyrometer (see Division G1) generates two trains of pulses synchronized with a chopper directing light from a target object and a standard lamp to a photo-multiplier alternately, the pulse having a duration dependent upon the standard lamp current and determined by a monostable circuit used alternately for the two trains. Transistors 51A, 51B have their bases unconnected and receive light alternately through the chopper 11 to produce rectangular pulse trains A1, A2. These pulse trains are differentiated and the negative spikes are used to set a monostable multivibrator 50. The multivibrator resets after a time determined by the output of non-linear amplifier 35 the input of which is indicative of the standard lamp S current. The output D of multivibrator 50 is fed to the inputs A81, B81 of two coincidence gates 60A, 60B, the other inputs of which are respectively the pulse trains A1 and A2. The pulses D are thus separated into two series of interlaced pulses E1 and E2.
