Abstract: A venturi-type rod scrubber (10) for effecting the cleaning of the flue gas produced as a by-product of the combustion process that occurs during the course of the operation offossil fuel firing steam generators, before the flue gas flows up the exhaust stack and is released to the atmosphere. 
     The subject scrubber includes inlet means (14) through which the flue gas enters the scrubber (10) and outlet means (36) through which the flue gas exits from the scrubber (10). 
     A first spray system (28) is suitably mounted in juxtaposed relation to the inlet means (14) so as to be operative to introduce liquid into the stream offlue gas entering the scrubber (10) through the inlet means (14). In alignment with but in spaced relation to the inlet means (14), the scrubber (10) is provided with a throat region (34) i.e., a region of restricted cross-section. A plurality of spaced rows of parallel rods (40) are suitably mounted within the throat region (34) so as extend substantially perpendicular to the path (12) of flow of the flue gas flowing therethrough. Interposed between the inlet means (14) and the throat region (34), the scrubber (10) is further provided with a second spray system (38) that is also operative to introduce liquid into the flue gas stream. The first spray system (28) and the second spray system (38) mutually cooperate to effect an even distribution of liquid across the entire cross-sectional area (32) of the throat region (34) that is being traversed by the flue gas as the latter flows through the scrubber (10). This even distribution of liquid provides for an efficient removal of the particulate matter, entering the scrubber (10) in entrainment with the flue gas. Concomitantly a reduction is achieved in the amount of particulate emission being released from the stack to the atmosphere.

Abstract: The moving target indication circuit (MTI) in a pulse Doppler radar comprising an arrangement for coherent integration is the cause of partial correlation of the noise voltages. The noise voltages of the output pulses of the moving target indication circuit are therefore partially correlated which results in a loss in the integration gain of the signal/noise power ratio during the subsequent integration. To avoid this loss, a weighting of the signal pulses is carried out in a weighting multiplier between the moving target indication circuit and the coherent integration. <IMAGE>

Abstract: In the production of hydrogen fluoride gas for the production of AIF 3  by the reaction of fluorspar with concentrated sulphuric acid a small amount of aluminium sulphate is introduced into the reactive mix to assist in the retention of phosphorous compounds in the solid residues of the reaction and thus reduce the phosphorous content of the gaseous HF. Aluminium sulphate may be added as alum or may be generated in situ in the sulphuric acid by addition of an alumina hydrate, preferably before the acid is brought into contact with fluorspar. The addition of a small amount of calcium carbonate to the fluorspar also improves retention of phosphorous compounds in the solid residues in some instances.

Abstract: The invention relates to a method for regenerating by crystallization on cooling pickling bath solutions based on sulphuric acid or hydrochloric acid and used for pickling iron, steel and other iron alloys. According to the invention the bath solution is regenerated in a combination of three stages. In a first stage acid is added to the solution in a concentration higher than the acid concentration of said solution, and the content of phosphoric acid is adjusted to be maintained between about 0.01 and 1 mole per litre solution, thereby to approach or to exceed the solubility of difficultly dissolved iron salts corresponding to the acid. In a second stage the solution is cooled, whereby iron salts precipitate. The cooling process is effected so as to reach a temperature at which the contents of iron and acid in the residual solution are suitable to permit said solution to be used again for pickling purposes. In a third stage the precipitated iron salt is removed from the solution, whereafter the regenerated pickling solution is returned for use at the pickling process.
