Abstract: Hot fumes, e.g. at 170-240 deg.C, from fossil fuel burning plant pass inside heat exchanger tubes to be cooled by external cooling medium, and then enter a condenser reducing fume temp. below the dew point, resulting in condensate which dissolves pollutant gases and drops into a vessel.  Downstream of the condenser, residual fumes pass through sprays of cooling water and these form the cooling medium applied to the exchanger tubes.  The condensate reception vessel is divided into chambers through which the condensate flows, alternately above and below the intermediate partitions; the chambers are filled with solid material, e.g. lime, for reacting with dissolved pollutants, (SO2 etc.).

Abstract: The invention solves the problem of pattern recognition in a temporal signal that is subject to distortions and time warp. The arrangement embodying the invention comprises a neural network, an input interconnection network, and a plurality of signal modification circuits. A plurality of input leads delivers a preselected characteristic stimulus to associated signal modification units, and in response to an applied stimulus, each signal modification unit develops a plurality of output signals that begins at the time of stimulus application, rises to a peak, and decays thereafter. The mean time delay of each output (time to reach the peak) is different for each of the modification unit output signals. The outputs of the signal modification units are applied to the input interconnection unit wherein connections are made in accordance with the sequences that are to be recognized.

With a second compound comprising a cation capable of donating a proton and a bulky, labile anion containing a single boron atom, and a plurality of aromatic radicals capable of stabilizing the zirconium cation formally having a coordination number of 3 and a valence of +4 which is formed as a result of the combination, said second compound having the general formula:         [L'-H]<sup>+</sup>[BAr<sub>1</sub>Ar<sub>2</sub>X<sub>3</sub>X<sub>4</sub>]<sup>-</sup>Wherein:L' is a neutral Lewis base;H is a hydrogen atom;[L'-H]<sup>+</sup> is a Bronsted acid;B is boron in a valence state of 3;Ar<sub>1</sub> and Ar<sub>2</sub> are the same or different aromatic or substituted-aromatic hydrocarbon radicals which may be linked to each other through a stable bridging group; andX<sub>3</sub> and X<sub>4</sub> are, independently, selected from the group consisting of hydride radicals, halide radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like. Many of the catalysts thus formed are stable and isolable and may be recovered and stored. The catalysts may be preformed and then used to polymerize olefins, diolefins and/or acetylenically unsaturated compounds either alone or in combination with each other or with other monomers or the catalysts may be formed in situ during polymerization by adding the separate components to the polymerization reaction. The catalyst will be formed when the two components are combined in a suitable solvent or diluent at a temperature within the range from about -100°C to about 300°C. The catalysts thus prepared afford better control of polymer molecular weight and are not subject to equilibrium reversal. The catalysts thus produced are also less pyrophoric than the more conventional Ziegler-Natta olefin polymerization catalysts.

Abstract: A digital GMSK filter for use for frequency modulation of a carrier signal in a GMSK transmission system is described. The GMSK filter uses a large number of individual current sources, whose current values are individually weighted. The current sources are driven via a control logic module using a shift register with a thermometer code, such that this results in a total current with a Gaussian characteristic, which is converted across a resistor to a voltage and drives a voltage controlled oscillator (VCO). The filter provides exact implementation of the sample values, virtually without any quantization error, and requires only a small chip area for its implementation.
