摘要： Sodium hydroxide is formed from sodium sulphate by a three step operation comprising converting the sodium sulphate to sodium sulphide, converting the sodium sulphide to sodium bicarbonate, and converting the sodium bicarbonate to sodium hydroxide. The operations preferably are effected in conjunction with a bleached kraft pulp mill operation, so as to utilize by-product sodium sulphate from chlorine dioxide generation to produce useful sodium hydroxide as sulphur without co-producing chlorine.

摘要： Hydrogen sulfide is removed from gas streams by reaction with sulfur dioxide to produce sulfur. The reaction is effected in a reaction medium comprising a non-aqueous Lewis base with a pKb value of about 6 to about 11. The reaction medium possesses a specific combination of properties: a) absorbs sulfur dioxide and reacts chemically therewith to form a reaction product; b) absorbs hydrogen sulfide; c) removes the hydrogen sulfide from the gas stream through contact of the gas stream with the reaction medium in the presence of free sulfur dioxide, and/or the reaction product; d) acts as a catalyst for the overall reaction of the hydrogen sulfide with sulfur dioxide to produce sulfur; and (e) has the capacity to absorb sulfur dioxide in sufficient quantity to remove substantially all the hydrogen sulfide from the gas stream, notwithstanding short term variations in the stoichiometric balance between the hydrogen sulfide and the sulfur dioxide in the reaction medium.

摘要： A method and apparatus for correlating two time series of digital quantities comprising means for converting one of the time series to a sign bit series and means for algebraically summing values of the second series which occur at times corresponding to the zero crossings of the sign bit series. The algebraic summation includes the modification of the signs of the summed values according to the direction of the zero crossing which occurs in the sign bit series. The preferred embodiment is a field correlator for use in geophysical seismic surveying to monitor data as it is recorded. The field correlator converts a digitized pilot signal into a sign bit only series, which is then correlated to a digitized record of a geophone spread output by summing only those samples of the geophone outputs which correspond to zero crossings of the pilot signal for a given lag value. As in standard correlation, the summation is repeated for each lag of the pilot relative to the detected signal so that an earth spikes trace is generated.

摘要： Two or more different polymeric materials are stably incorporated into bitumen by effecting steric stabilization of a polyolefin, such as polyethylene, and by dispersing the other polymer, such as a styrene-butadiene-styrene copolymer, an ethylene-vinyl acetate copolymer or an EPDM copolymer in the stabilized polyethylene-bitumen composition. The ability to incorporate different polymeric materials in bitumen permits desirable modifications to the properties of the composition to be effected. In addition, different properties can be attained by modifying processing parameters.

摘要： Components, usually but not exclusively gaseous components, are removed in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. The same principal may be employed in other procedures in which a gaseous phase is dispersed in a liquid phase to effect an interaction between components present in such phases. A gas-liquid contact apparatus, generally a combined chemical reactor and solid product separation device, comprising such modified agitated flotation cell is also described. In order to effect mass transfer and rapid reaction gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index of gas through the openings in the shroud is at least about 18 per second per opening. Each of the openings has an area corresponding to an equivalent diameter of less than about one inch.

摘要： This invention is directed to insect control using compositions having attractants, feeding stimulants and toxicants compounded into plastic bait pellets. These pellets are easily handled for distribution in the field. Insects are attracted to the bait pellets, induced to feed and subsequently die. The pellets have the unique advantage of being relatively impervious to environmental conditions and non-polluting.
