Abstract: Abstract of the Disclosure The invention relates to a process for producing a hydrogenated conjugated diene polymer.  The carbon double bonds of a conjugated diene polymer are hydrogenated in a solvent using a catalyst composed of hydrogena-tion catalyst supported on a carbon carrier having an average particle diameter of 5 mµ to 10 µ and a specific surface area of 5 to 200 m2/g.  After the hydrogenation reaction the hydrogenated conjugated diene polymer is separated from the solution of the hydrogenated polymer without separating the catalyst therefrom.

Abstract: 1574              LOW TEMPERATURE, NON-SO2 POLLUTING, KETTLE PROCESS FOR SEPARATION OF LEAD FROM LEAD SULFIDE-CONTAINING MATERIAL                        ABSTRACT OF THE DISCLOSURE                  Lead is separated from material containing lead sul-fide, e.g. galena ore concentrate, by a substantially auto-genous process involving establishing a pool of molten lead in a kettle, adding a metallic alkali metal, e.g. metallic sodium to the molten lead in an amount sufficient to reduce the com-bined lead of the lead sulfide to metallic lead, adding the ore concentrate to the molten lead pool, and mixing together the metallic sodium, molten lead and ore concentrate. The sodium reacts rapidly and exothermically with the lead sulfide to reduce the combined lead of the lead sulfide to metallic lead and form sodium sulfide. The thus-liberated metallic-lead reports in the molten lead pool, and a matte phase con-taining the sodium sulfide separates from the molten lead and forms on the surface of the molten lead pool. Lead sulfide from an excess of the ore concentrate, or other suitable added flux, which is usually added to the molten lead pool, serves to flux the sodium sulfide-containing matte phase to attain , desired fluid and low melting characteristics of the matte phase.  The process herein employs a kettle as the reactor, ordinarily the steel refining kettle of a lead refinery, is a low temperature process requiring temperatures above the melting point of lead but ordinarily not above 650°C., and does not discharge polluting SO2 into the atmosphere.

Abstract: Abstract A method and apparatus for substantially reducing emissions of nitrogenous compounds such as NOX formed during fuel combustion.  The fuel is combusted with an oxygen-containing gas in an amount from about 45 to 75% of the total stoichiometric amount of oxygen required for complete combustion of the fuel.  The resulting mixture of fuel and combustion products, including NOX, is maintained at a temperature of at least 1800°K for a time sufficient to reduce the NOX content of the mixture to a desired level. Thereafter, combustion may be completed in one or more additional zones at a temperature within the range of about 1600° to 2000°K.  Alternatively, the mixture of combustion products and fuel having a reduced NOX content may be used for other applications without further combustion.  For certain embodiments of the invention, various particulates may be added to the combustion zone so as to enhance the rate at which the NOX is destroyed.     .:

Abstract: Abstract of the Disclosure A dot matrix character printer having the capability of printing characters at variable speeds and with variable pitches.  Variable pitch is provided through the use of programmable radix counters which control actuation of the printing solenoids.  Solenoid actuation is based on print head position, with the actuation position being varied with print head velocity, to compensate for the distance travelled by the print head during the time between solenoid actuation and print wire impact; this permits operation at variable printing rates.  Printing rate is limited by the cyclic rate of the print head, with an additional limitation based on dot printing density which prevents excessive heating of the printing solenoids.
