Abstract: A method of recycling the off gas from an ozone disinfection step used with an activated sludge waste water treatment system, and apparatus for carrying out the method. The moisture is removed from a substantial portion but not all of the ozonation off gas, while the nitrogen and carbon dioxide contaminants that are contained in the off gas are left in it. The dried off gas is mixed with oxygen enriched gas from the original source, and the resulting mixture is delivered to the ozone generator for the production of more ozone. Another portion of the ozonation off gas is diverted upstream for introduction into the oxygen treatment facility of the activated sludge treatment plant. The drying of the ozonation off gas is preferably carried out by use of a two cycle self-purging dryer, with the portion of the ozonation off gas that is not delivered as a recycle component to the ozone generator utilized as the purge gas for the dryer before it is recycled upstream.

Abstract: Method of separating sulphur dioxide and other unwanted gas components from a gas flow, such as smoke gas from a coal-fired power plant. The smoke gas is brought into contact with an absorbent, which reacts with sulphur dioxide, after which the reaction products can be separated from the gas flow in a filter. According to the invention, a dry absorbent is used, which is made to form a dust layer on the filter material. The absorbent consists of an oxide, a carbonate or a hydroxide of an alkaline earth metal or an alkaline metal. The water required for the reaction is supplied to the gas flow Q in finely divided form, upstream from the filter material, either in a specially arranged treatment tower 2 a-c or directly in the filter chamber 3 a-c. Before cleaning the filter, the water supply can be interrupted, thereby obtaining fast drying of the powder layer, which facilitates the cleaning operation. It is convenient to use several parallel treatment lines, and the gas flow q a-c to the respective filter chambers 3 a- c can be shut off during the cleaning process itself. During trials at an experimental layout, where a bag filter with a filter surface of 10.6 m<2> was loaded with a powder cake of calcium hydroxide until the pressure drop across the filter material was 120 mm water pressure, there was run a gas mixture with a temperature of 155 degrees C, flow rate of 700 m<3>/h, and sulphur dioxide content of 430 ppm. Water was supplied to the gas flow so that its temperature dropped to 42 degrees C, the sulphur dioxide content was brought down to 65 ppm. After 4 hours of operation, the experiment was interrupted and it was possible to clean the bag filter in normal fashion. <IMAGE>

Abstract: An analog carrier signal and its sidebands contain modulated information which is to be digitally encoded and processed. Demodulation and digital encoding is accomplished in a single process by an analog-to-digital converter, which samples the analog signals in response to a sampling signal of a frequency which is at least twice the bandwidth of the band of frequencies containing the carrier signal and its information-bearing sidebands. The analog signal samples are digitally encoded, producing a band of digital information signals corresponding to baseband signal components. When used in a television receiver to produce digital signal samples, the band of analog signals may include both sound and picture carriers and their audio and video information. By controlling the phase and frequency of the analog carrier signal in relation to the color subcarrier signal, and deriving the sampling signal from the analog carrier, an ease in video signal demodulation is provided.

Abstract: A radar warning unit is installed in the aircraft, and records the position and type of anti-aircraft units on the ground beneath its path towards a target, where the units also use radar. The areas of effect of the units are assessed, taking account of the aircraft relative position, course and speed. An optimal path for the aircraft is determined from such areas of effect, and the requisite manoeuvres are enacted by the pilot to bring the course of the plane to coincide with the determined optimal path. The manoeuvres are put into effect on an ongoing basis to ensure the best use of the optimal path. The manoeuvres are indicated in the sight line indicator of the aircraft, pref. in the form of an arrow, the direction of which indicates the changed path to be followed. The lateral position of the arrow in relation to the central vertical line of the sight line indicator is a dimension of the actual available margin for the manoeuvre.

Abstract: The invention relates to a method for preparing a sui- phidic concentrate which is intended for further processing to copper and/or precious metals and which contains high percentages of arsenic and/or antimony, and possibly also bismuth in quantities likely to disturb subsequent processing stages, by partially roasting the concentrate in a fluidized bed, so as to eliminate substantially all the arsenic present and a major part of the antimony and/or bismuth. According to the invention, the concentrate and gas are supplied to a fluidized-bed reactor, and are there heated to a minimum temperature above the splitting or decomposition temperatures of the complex minerals containing arsenic and/or antimony and bismuth present in the concentrate. The oxygen potential in the reactor is regulated, so as to prevent the formation of non-volatile compounds of said impurities. The residence time of the concentrate in the reactor is controlled in a manner to ensure a given minimum elimination of the impurities. The gas and solids are withdrawn from the reactor and passed to a separating means, in which substantially impurity-free solids can be separated from the gas. The aforesaid minimum temperature and said regulated oxygen potential are maintained while the solids are in contact with said gas, and at least a part of the separated solids is returned to the reactor, for controlling the residence time, and an end product is removed from the fluidized bed and/or the separating means. The method is suitably carried out in one stage in a fluidized-bed reactor having a circulatory fluidized bed, although in certain cases the method can be carried out in two stages, in mutually separate reactors.

Abstract: A downflow, gravity type gasifier includes a vertically oriented chamber having a loading zone at the top, followed by a drying zone, followed by a pyrolytic zone for pyrolytic decomposition, followed by a cracking zone for cracking the tars, followed by a reduction zone and an oxidation zone wherein the gas is generated and the combustible material is burned. The cracking zone has a divider, e.g. a cruciform divider, in it, and each of the resulting sections of the cracking zone is individually supplied with air for more uniform distribution of air and more uniform cracking than heretofore available. In addition to the air supplied to the periphery at the cracking zone, air outlets are arranged in respective radial arrays of the outlets for more uniform distribution of air into the reduction and oxidation zone. Steam is generated in the cooling water jacket surrounding the oxidation zone and that steam is delivered into and passed through the interior of a cruciform-shaped radiator disposed in the drying zone for heating the drying zone. The air from the arrays of air outlets creates an additional oxidation zone performing additional oxidation, so as to deliver substantially tar-free gas from the gas outlet of the gasifier.
