Title: Process for recovering ammonia and ammonium compounds from gases
IPC: C01C1/12
Filed: 1924-06-18
Abstract: 239,934. Forst, P. von der. June 18, 1924. Ammonium chloride; ammonia.-Free ammonia and ammonium compounds are obtained separately from gases containing them by washing by means of a jet-blower or similar apparatus at a temperature somewhat above the dew point with a circulating aqueous liquor obtained from the gas itself by condensation whereby the tar mist and fixed ammonium salts are removed from the gas which is then treated for the recovery of the free ammonia. In the plant shown in the Figure a gas such as coal gas is washed by means of a jet-blower a at a temperature above its dew point and then passes to a cooler b. Although the temperature of the gas leaving the latter is adjusted by cooling or even heating in order to keep it still somewhat above the dew-point condensation occurs locally near the walls so that the washing liquor containing the fixed ammonium compounds increases continuously and is led to a tank m from which it is circulated by means of a pump p. The quantity which is not required for washing the gas is concentrated to the point of crystallization by circulating it through a scrubber g in which it meets an upward current of hot air or other gas. The liquor is preferably neutralized by means of hydrchloric acid before it is concentrated to avoid removal of any free ammonia present. An alkali such as ammonia is added during concentration however to prevent the liquor becoming acid. The cooler k is provided to recover any ammonia which escapes, just sufficient water only being condensed to retain the ammonia; the minimum temperature is also employed in the scrubber g to avoid loss of ammonia as far as possible. The gases leaving the cooler b may be passed directly to an acid saturator, or mav be further cooled in a tower c to obtain ammonia liquor which is run off to a tank n. The ammonia may be liberated by distilling with steam and passed to a saturator, or the liquor may be heated by means of any available source of heat, for example by using it to cool the gases in the cooler b and then sprayed into the gas stream entering the saturator. The tar separating in the cooler b is preferably extracted with ammonia solution in order to recover the ammonium salts present, and phenols may be recovered from the waste liquors from the ammonia stills by subjecting them to a current of air. By addition of sodium chloride to the fuel prior to distillation, most of the ammonia may be obtained in the form of chloride.

Title: Improvements in radio direction finding
IPC: G01S1/02
Filed: 1949-06-03
Abstract: 679,835. Radio direction finding. DEHN, S. G. (Collins Radio Co.). June 3, 1949, No. 14971/49. Class 40 (vii). The invention consists of a modification of the type of direction finder, Fig. 1 (not shown), wherein the signal output of a loop aerial is modulated in a balanced modulator by a local signal, the modulator output being phaseshifted by 90 degrees and combined with the output of an omnidirectional sense aerial for application to a superheterodyne receiver whose second detector output is a signal of the local signal frequency which may be fed to a product detector with the local signal to produce a potential at the output whose magnitude and sign is representative of the deviation of the loop aerial from the null position. According to the invention, the loop aerial signal fs is modulated by a low-frequency fb obtained by mixing the local signal fo with the beat fre. quency derived by mixing the omnidirectional aerial signal fs with the superheterodyne oscillator signal fc and the low frequency is time delayed before its application to the modulator. The modulator output is applied without phase shift and in combination with the omnidirectional aerial signal to the superheterodyne receiver input and the I.F. amplifier output of fs - fb -fc, i.e. fo, is compared in a product detector with the local signal fo phase shifted by 90 degrees to give an output at 11 indicating deviation from the null position. The Specification explains why the modified direction finder gives satisfactory results under random signal noise conditions which would make it impossible to obtain results with the usual type of apparatus. The delay in the selective amplifier 14 selecting and amplifying the modulating signal is normally adequate without the introduction of further delay. The 90 degrees phase shift indicated as being obtained in circuit 17 may if desired be introduced in the output of amplifier 14 instead. A tuning indicator 16 is provided as correct tuning is essential for correct results. In a variation (Fig. 3 (not shown), Fig. 3 shows schematic circuits for some of the units), the output of amplifier 14 is periodically reversed in phase by motor-driven cam-switching means and the corresponding output of the product detector is therefore an alternating potential which may be readily selected and amplified before rectification mechanically by means of contacts operated in synchronism with the reversing means.
