Patent GB-661064-A (GB)
Title: Automatic gain control
IPC: H04N5/53
Filed: 1949-05-11
Abstract: 661,064. Automatic gain control. RADIO CORPORATION OF AMERICA. May 11, 1949, [May 28, 1948], No. 12578/49. Class 40 (v). In an automatic gain control system a direct current is varied in response to an incoming carrier signal and is passed through a primary winding of a saturable reactor, thus varying the impedance of the secondary winding through which a periodic current is passed which is rectified to produce the gain control voltage. Fig. 1 shows a gain control system for a sound receiver in which the incoming carrier passes through the mixer 9, I.F. amplifier 19 and second detector 1 of a conventional superheterodyne receiver. The D.C. control voltage produced by the diode D1 across resistor 3 varies the cathode current flow in the mixer stage 9 and thus the D.C. current passing through the primary winding P of the magnetic amplifier transformer 11. The impedance of the secondary windings S to which an A.C. voltage at the mains supply frequency is applied is thus varied by the current flow in the winding P and a D.C. control voltage is produced by diode D2 at point 15 which is thus a function of this current flow. The control voltage at point 15 is applied to the cathode of the I.F. amplifier stage 19 to control the gain of this stage. Fig. 2 shows the application of such a gain control system to a television receiver. The incoming signals are applied via the R.F. amplifier stage 21, mixer 23, I.F. amplifiers 25 and 27 to the second detector 29 and video amplifier stage 31. The anode current of the video amplifier stage 31 is applied to the winding P of the magnetic amplifier 11 to the secondary of which the line synchronizing signals are applied. The control voltage produced by rectifier 35 is thus only present during the line synchronizing signal periods and is controlled by the D.C. current flow in the video amplifier stage 31. The D.C. control voltage across resistor 36 is applied to vary the gain of the R.F. amplifier and I.F. amplifiers stages. Specifications 449,242, [Group XXXV], and 458,585 are referred to.

Title: Process and apparatus for the production of nitric acid from nitrous gases
IPC: B01D47/06
Filed: 1951-05-31
Abstract: <PICT:0692071/III/1> In the production of nitric acid by the oxidation and absorption in aqueous media of nitrous gases, such as are obtained by the oxidation of ammonia, the nitrous gases in admixture with elementary oxygen are passed upwardly through a tower containing two or more superposed packed reaction zones, countercurrent to an absorption liquid which overflows from each zone to the next lowest zone.  The liquid in each zone is pumped through separate coolers for each zone and recycled thereto; the cooling medium passes successively through the coolers from that for the uppermost zone to that of the lowermost.  The size of the zones may increase, as the temperature decreases, from the bottom to the top of the tower.  As shown in Fig. 2, three superposed annular packed zones 26, 25, 24 having heat exchangers 36, 51, 52 respectively are arranged around a central pipe 22.  Water or dilute nitric acid is added to the system at 54 and liquid is withdrawn from each zone, circulated through the cooler for that zone and recycled to sprays 37, 38a, 38, above the respective zones.  A cooling medium such as brine passes through coolers 36, 51, 52 in succession.  The nitrous gases enter at 23 and pass upwardly through the zones countercurrent to the absorption liquid.  Unabsorbed gas is withdrawn from central tube 22 and may be passed to further towers.  Product acid is withdrawn at 53.  A portion of the liquid collecting at the bottom of each zone passes through perforations in the collecting system to the next lower zone whilst the remainder is recycled via the cooler, preferably to a spray such as 38a made up of an annular chamber surrounding tube 22, formed with an annular slot on its lower side. A cone 47 which may be perforated, directs the spray over the whole area of the zone.  The packing in each zone may be supported on segmented plates resting on flanges on the tube 22 and the outer walls of the tower.  The segmented plates preferably have upturned radial edges and troughs may be provided on the underside.
