    摘要： A method for the preparation of a salt mixture useful for hardening steel parts, including of potassium cyanate, potassium carbonate and sodium carbonate, wherein 2.2 to 2.3 moles of urea is first reacted with 1 mole of potassium carbonate to form potassium cyanate. The escaping ammonia is converted with formaldehyde into hexamethylenetetramine. The reaction product, which is potassium cyanate and potassium carbonate, is ground, mixed with powdered sodium carbonate and pressed at between 80.degree. and 230.degree. C. into shaped pieces.

    摘要： Composition, method and apparatus for providing a surface stabilized source of HNCO by adsorbing gaseous or liquid HNCO on the surface of a substrate. HNCO stabilized in this manner is not reactive and is stable at or above ambient temperature. The HNCO can be provided by heating a reactant source material, such as urea. The substrate can be heated to release HNCO. The present invention is especially useful as a source of HNCO for reducing NO.sub.x in gas streams.

    摘要： The present invention incorporates new and useful improvements in the carbon dioxide sequestering mechanism of Ref. 1 of the Cross References. The ejector systems of Ref. 1 are rearranged in a manner that lowers the frictional effects of the resultant flow pattern after the flue gas and ejector spray have impacted in the receiver mechanism. The sequestered carbon dioxide resulting from the collision is retained in the scrubber water matrix for a prolonged period by adding a wedging mechanism designated as a compression band which extends the duration of the sequestering operation for a sufficient period of time for the absorbed gases to exit the receiver with the scrubber water flow into a separator vessel.
