Patent GB-434302-A (GB)
Title: Improvements in or relating to the absorption of nitrogen oxides
IPC: C01C1/18
Filed: 1934-07-11
Abstract: Nitrogen oxides are absorbed from gases leaving the acid absorption in the manufacture of nitric acid from the oxidation products of ammonia (i.e. gases consisting of the greater part of nitrogen and containing a few per cent of oxygen, a small proportion of nitrogen oxides and some water vapour) by reacting the gases with ammonia in the absence of substantial proportions of carbon dioxide to yield a mixture of ammonium nitrate and ammonium nitrite.  Preferably, ammonia gas is added to the gases after which the gases containing ammonium nitrite and ammonium nitrate in the form of mist are brought into contact with water, ammoniacal water, or aqueous salt solutions, e.g. aqueous ammonium nitrate, preferably in counter-current. Alternatively, the gases may be lead into ammoniacal water; or both these means may be used.  Preferably, a slight excess of ammonia is used.  The resulting solution of ammonium nitrite and nitrate may be converted by treatment with acids, such as nitric acid, sulphuric acid or hydrochloric acid, into solutions of the corresponding ammonium salts.  Crude nitric acid from the acid absorption system of a nitric acid plant may be so employed.  Air may be passed through the solution during this production of ammonium salts. The nitrogen oxides set free may be returned to the acid absorption system.  The solution containing ammonium nitrite may be added to the nitric acid from the acid absorption system during or before the last manipulation to be applied to this acid, viz. the so-called bleaching or blowing with air.  The liberated oxides of nitrogen are returned to the acid absorption, whilst the nitric acid-containing ammonium nitrate is worked up to pure ammonium nitrate or mixtures containing ammonium nitrate.  The Specification as open to inspection under Sect. 91 comprises also increasing the capacity of the ammonia burners of an existing nitric acid plant without providing extra nitric acid absorption towers, a gas containing a higher proportion of nitrogen oxides leaving these towers for treatment with ammonia. In addition, the above referred to treatments with air may be conducted with other gases such as oxygen or air containing oxygen. Gas distributers such as porous stones, perforated or porous stoneware pipes, &c. may be used for this purpose.  This subject-matter does not appear in the Specification as accepted.

IPC: G01V3/11
Filed: 1963-05-23
Abstract: 1,092,362. Detecting conductive and magnetic bodies. MOLINS MACHINE CO. Ltd. May 22, 1964 [May 23, 1963], No. 20643/63. Heading G1N. The presence of an electrically conductive or magnetic particle in a non-conductive material (e.g. cigarette tobacco or jam) is detected when the particle moves into or out of the field of an inductor thereby changing the Q factor of a parallel tuned circuit comprising the inductor and connected in series with a resistor across the output of an oscillator. As shown Fig. 1 the tuned circuit L. C. and the resistor R form a voltage divider 2 and in operation the oscillator produces a constant amplitude and frequency output which is delivered thereto. The voltage across the tuned circuit is applied to a detector and so long as a cigarette rod 7 passing through the inductor field contains no conductive or magnetic material the signal received by the detector circuit 3 will be steady and the detector circuit will deliver a steady D. C. output to an amplifier 4. However no signal will be delivered at the output of the amplifier which is an A. C. amplifier. When a said particle enters the inductor field the effective ratio of the voltage dividing circuit will change, the input from the oscillator being constant, and the detector will produce a pulse which is amplified and stretched in a pulse stretcher circuit 5 and may be used to operate a relay 9 in a control circuit or alarm circuit of the cigarette making machine. The said circuits are said to be of known type and are detailed in Figs. 2A, 2B, 2C (not shown).

Filed: 1960-06-15
Abstract: 922,128. Infra-red gas analysers. Sir HOWARD GRUBB PARSONS & CO. Ltd. June 15, 1961 [June 15, 1960], No. 21078/60. Class 40 (3). An infra-red gas analyser for the analysis of two or more components in a gas mixture comprises two separate radiation paths 2, 3, means in one path 2 for receiving the mixture, detection means 4 sensitive to wavelengths capable of being absorbed by each component to be determined, the detection means producing a signal whose magnitude is a measure of the difference in energy reaching it over the two paths, and wavelength selection means comprising interference filters, each transmitting a narrow wavelength band coincident with a region of absorption by one component, the filters 8a being movable one at a time into at least the radiation path 2 containing the test mixture. Radiation from each of two sources 1a and 1b is interrupted simultaneously by a chopper 7, that from one 1a being passed through the test mixture 2 and that from the other 1b being passed through a comparison gas 3 exhibiting constant absorption properties. Unequal absorption in the two paths results in a pressure difference between two chambers 4a and 4b of the detector 4, the chambers being filled with a gas exhibiting similar absorption properties to the test mixture, this difference producing deflection of a diaphragm 5 relative to a fixed electrode 6 to produce a pulsating signal whose magnitude is indicative of the relative absorption. Interference filters 8a and 8b are mounted, Fig. 2, to be rotated respectively into the radiation paths to select in turn each wavelength range appropriate to the components being analysed. The filters for the two paths may be mounted in a common carrier which may be rotated or moved linearly, and the movement may be remotely controlled. Instead of identical filters in the two paths, one or both may incorporate an adjustable optical trimmer such as a screw projecting into the radiation path and these screws may be adjusted for equal path energy content when no sample is present. An attenuator may be used in one path in place of a filter.
