Abstract: The present invention relates to novel pharmaceutical compositions based on anticholinergics of the formula 1; wherein X?, R1 ? and Ar are defined as in claim 1, and a heterocyclic compound of the formula 2. Furthermore, the invention relates to processes for preparing them and their use in the treatment of respiratory complaints.

Abstract: The present invention provides a therapeutic and/or preventive agent for pulmonary disease that exhibits neutrophilic inflammation, such as, chronic obstructive pulmonary disease (COPD), pulmonary emphysema, chronic bronchitis, acute respiratory distress syndrome (ARDS), acute lung injury (ALI) and the like, which comprises 7-[2-(3,5-dichloro-4-pyridyl)-1-oxoethyl]-4-methoxy-spiro[1,3-benzodioxol-2,1?-cyclopentane] or a pharmaceutically acceptable salt thereof as an active ingredient.

Abstract: A steel material subjected to preliminary treatments to remove an oxide film on the surface is immersed in a molten flux bath in an independent vessel and thereafter immersed in a molten zinc-aluminum alloy bath in a separate vessel to be galvanized with a coating of the alloy. The molten flux bath consists essentially of 5-25 wt % of an alkali metal chloride, typified by sodium chloride, or an alkaline earth metal, and the balance being zinc chloride. The flux bath may additionally contain 1-5 wt % of an alkali metal fluoride typified by sodium fluoride. The method allows for inexpensive, efficient and one-stage galvanizing with a corrosion-resistant molten zinc alloy of a high aluminum content to produce a smooth, uniform and beautiful galvanized layer on the surfaces of various steel materials.

Abstract: The improved method achieves effective and economical decomposition of hydrogen peroxide and may be used in recycling hydrogen peroxide-containing spent sulfuric acid that has been used in wafer cleaning and other operations in the process of semiconductor fabrication or in removing residual hydrogen peroxide that will occur either within the papermaking process or in plant effluents as a consequence of a shift from chlorine-containing bleaching agents to oxygen-containing bleaching agents.When coke was added in an amount of 10 wt % to a solution of 0.88 wt % hydrogen peroxide in 72.6 wt % sulfuric acid, followed by treatment at 60.degree.-70.degree. C. for 4 hours, the concentration of hydrogen peroxide dropped to 0.0001 wt % and below. When coke was added in an amount of 10 wt % to each of a solution (pH, 0.94) of 1.0 wt % hydrogen peroxide in 1.1 wt % sulfuric acid and a solution (pH, 2.58) of 1.04 wt % hydrogen peroxide in sulfuric acid followed by treatment at 60.degree.-70.degree. C.
