Abstract: A method and apparatus are employed to reduce the sulfur dioxide produced by the combustion of a sulfur-containing fuel in a combustion chamber. Part of the combustion air is introduced into the combustion chamber with and closely adjacent the fuel. Another part of the combustion air is introduced into the combustion chamber above and downstream of the fuel and relatively remote therefrom under conditions which buffer the flame front and reduce peak flame temperatures therein. Finely divided limestone particles or the like are aspirated into the combustion chamber by the air introduced above the fuel and distributed thereby throughout the gases flowing downstream through the combustion chamber wherein the limestone particles are calcined to lime particles which react with the sulfur dioxide in the combustion reaction gases to produce calcium sulfate. There is no premixing of the particles and the aspirating air before they enter the combustion chamber. Various parameters are controlled to produce the desired results.

Abstract: The transmitter in a digital communication system sends a synchronization sequence that uniquely identifies the polarity of the received data. From the received data (418), the receiver produces non-inverted and inverted polarity data streams (358, 358ʹ) that couple to like synchronization detectors (200, 200ʹ). Only the detector to which the correct polarity data stream is coupled responds. Logic circuitry determines which detector responds and, accordingly, selects the polarity of received data to be further processed by the receiver (422). 
     After polarity is established (60), both detectors monitor the received data stream of the selected polarity to determine whether synchronization shifts after having been initially established. Monitoring continues until terminated by other receiver circuits.

Abstract: This vector magnitude approximating method uses logarithms of vector's orthogonal components to select multiplier scaling constants (K x ,K y ) and to minimize arithmetic-function and hardware complexity. The vector magnitude is approximated by multiplying (20,22) each component (X,Y) of a complex number representing the vector by selected scaling constants (K x ,K y ) and then by summing (24) the two resulting products (K x X,K y Y). The scaling constants (K x ,K y ) are selected by feeding each orthogonal component (X,Y) into one of two identical logic arrays (10,12) which determine the base-2 logarithm of the absolute value of each component. The resulting logarithm values are fed, in parallel, into a third logic array (14) which outputs an address to real and imaginary constant read-only memory generators (16,18) for providing respective scaling constant pairs (K x ,K y ) which are used in computing the approximate magnitude of the vector or complex number. The apparatus is particularly applicable to a high-throughput, pipelined, digital signal processing application such as radar.

Abstract: The method is to be used for determining the neptunium concentration present in an aqueous solution. The aqueous solution is treated in order to stabilize the neptunium it contains at the (V) oxidation state. The neptunium (V) is then determined by absorption spectrophotometry at a wavelength corresponding to an absorption peak of neptunium (V). The stabilization treatment involves adding to the solution sufficient quantities of a reagent under two oxidation states in order to reduce all the neptunium (VI) to neptunium (V) and to oxidize all the neptunium (IV) to neptunium (V). The reagent is chosen so as not to have any significant absorption at the wavelength used for the determination of the neptunium (V), for example at 981 nm. Preferably, a vanadium-based reagent is used, consisting of a solution of vanadyl sulphate partially oxidized by cerium (IV) ions. <IMAGE>

Abstract: Device for control and/or measurement of a test object which device supplements a conventional crack detecting equipment. The device detects the presence of, for example, disturbing magnetic material, such as cold oxide scales (2) in or on a test object (1), in order to ensure that disturbances origi­nating from magnetic material are not confused with surface crack without being discovered. By utilizing eddy current technique, oxide scales which are harmless to the process can be separated from dangerous surface crack, thus avoiding the scrapping of test objects which have actually no cracks. The invention is based on signal-processing of at least two signals originating from a transducer (3,4), by means of a vector transformation method, and separating, for example, oxide scales from cracks as a function of a comparison of signals, from at least two transformation blocks. This com­parison can be supplemented with conditions, for example digital condition functional blocks.
