摘要： To form an ionomer-based catalytic layer on a porous substrate, a heat source (40) is used to dry an ionomer-containing spray (46) so that it does not substantially liquid flow on the substrate (14). The ionomer spray (46) may contain a catalyst. A spray (46) of mixed material for forming the catalytic layer is entrained by a gas stream and is heated and directed to a substrate surface (12). For hydrogen/oxygen fuel cells, catalytic material is incorporated into the proton-conducting membrane (56) to convert diffusing oxygen and hydrogen to water to reduce potential loss at the electrodes and maintain hydration of the proton-conducting membrane (56).

摘要： Apparatus is described for rapidly coating a large area, or for rapidly producing a powder. In one embodiment, a liquid having a coating chemical is pumped from a liquid reservoir to a distribution manifold. From the distribution manifold, the liquid is carried under pressure to a geometric array, e.g., linear, of atomization nozzles. Flow equalization means are provided for equalizing the flow of the liquid delivered to each nozzle, and, preferably, means are provided for equalizing the temperature of the liquid delivered to each nozzle. The liquid, upon exiting the nozzles with the attendant pressure drop atomizes. The atomized liquid coats a substrate either in non-reacted or reacted form, or forms a powder. In a preferred embodiment, a solution of precursor chemical is reacted in a geometric array of flames produced at the nozzles, and a coating material produced in the flame coats the substrate, or a powder is formed. In another embodiment, vaporized precursor and vaporized are fed to a burner chamber having a linear exit slit. The vapor exiting the slit is burned, and material produced in a flame reaction are deposited on a substrate, or the powder formed is collected.

摘要： Tubular needles have a reduced inner diameter tip portion that increases back pressure behind the tip portion. This constricted tip portion promotes improved atomization, particularly when the liquid passes through the needle at near-supercritical conditions. A preferred method for constricting the inner diameter of a needle tip is to dip the dip of the needle in an electroless plating solution, such as an electroless nickel solution.

摘要： A method for generating new forward error correction codes, called skew codes, for the reliable transmission of data in noisy channels is disclosed. The method involves adding additional sets of parity equations across the third dimension of a cubic array of bits. The parity equations are applied to the cubic array such that the rectangular patterns of one square array do not match up with a rectangular pattern in another square array. By selecting skew mapping parameters of the parity equations from a set of quadratic residues of prime numbers according to specific design rules, the resulting codes are well suited to low-complexity high-speed iterative decoding, and have error correction performance and error detection capability, particularly for applications requiring high code rates. An improved decoding method for decoding skew codes and any code that is defined by a set of sum-to-identity parity equations initially decoded using an algorithm that provides confidence values on all the symbols at every symbol time is also disclosed. Generally, the improved decoding method will make hard decisions based upon the soft decisions passed from the failed iterative decoding system to provide a valid code word, through manipulation of the parity check matrix and reduction of its columns and rows.

摘要： A method of creating tail-biting recursive systematic convolutional and turbo codes, and the associated encoders, are described herein. According to the method, symbols from the set of data to be transmitted are used to preset the starting state of the encoder, and are replaced in a systematic set by an equivalent number of tail-biting symbols that force the ending state of the encoder to be the same as the starting state. The presetting of the starting state allows for simpler calculations in choosing the tail-biting symbols, and allows a message to be transmitted with a reduced number of symbols The reduction in the number of symbols used for overhead in this invention provides an increase in the data transmission rate.

摘要： A simplified method of history handling for the Viterbi decoding of convolutional codes is described herein. The state number, or one or more of the most-significant bits of the state number, is loaded into the corresponding state history. Each state number represents the sequence of data bits that, in convolutional encoding, would give rise to the corresponding state. The most recent data bit provides the least significant bit of the state number. This invention reduces the processing requirements associated with the handling of the history, and is especially useful for decoder implementations using general-purpose processors.

摘要： A method for determining at least one dynamic flow characteristic of a multiphase flow circulating in a pipe, the flow being composed of a lighter dispersed-phase and a heavier continuous-phase. A tracer is discharged (or activated) into the flow at a chosen first location in the pipe by mixing (or activating) a portion of the tracer with the continuous-phase therein. The tracer concentration at a chosen second location in the pipe is measured with a detector as a function of time t, so as to obtain a signal S(t). Then a relationship is fitted to the signal S(t) so as to derive the values of the velocity U of the continuous phase and/or of a dispersion coefficient k. The slip velocity v.sub.s of the dispersed phase relative to the velocity of the continuous phase is also advantageously determined. From the values of velocities U and v.sub.s and from the volume fraction y.sub.1 of the continuous phase in the pipe (obtained by an ancillary measurement), the volumetric flow rates of the continuous and dispersed phases are determined.

摘要： A method of encoding data is described herein. According to the method, source data elements are coded using one or more product codes having a common component code. The resulting one or more primary product codewords consist of a plurality of first codewords of the common component code. One or more first sets of codewords of the common component code are assembled such that each of the first sets comprises two or more distinct first codewords forming part of a same primary product codeword. Each of the codewords of each of the first sets is codeword-mapped to a second codeword of the common component code using a one-to-one codeword-mapping. One or more second sets of second codewords are provided, where each second set corresponds to a first set of codewords. The codeword-mapping includes re-ordering, according to a known interleaving pattern, the symbols within a codeword. The codeword-mappings are such that if all of the codewords of a first set are from a same primary product codeword, then some codeword-mappings applied to the codewords of the first set are different, and if two or more repetitions of a same codeword are included in a single first set, then the codeword-mappings applied to those repetitions are different. Each set of second codewords is coded using a systematic code so as to generate a secondary product codeword for a product code having as component codes the common component code and the systematic code. Then, the primary product codewords and the non-systematic portion of the secondary product codewords are provided as encoded output data.

摘要： A gradiomanometer 1 measures the difference in pressure between points 3 and 4 to indicate density and hence proportions of two phases (e.g. liquid and gas), each of known density flowing as indicated by arrow 6. A venturi meter 2 measures the difference in pressure between points 4 and 5 to indicate flow rate, initially assumed to be that of the heavier phase only. An iterative calculation makes it possible to obtain a density measurement corrected to allow for flow friction and individual flow rates of the two components, having regard to slippage therebetween. A step discontinuity 8 may be provided downstream to create turbulence and render the flow homogenous.
