Abstract: A process for preparing a polymer-coated hard shell capsule can be performed. The hard shell capsule has a body and a cap. In the closed state the cap overlaps the body either in a pre-locked state or in a final-locked state. The hard shell capsule is provided in the pre-locked state and coated with a coating solution, suspension or dispersion that has at least one polymer; at least one glidant; at least one emulsifier; optionally at least one plasticizer; optionally at least one biologically active ingredient; and optionally at least one additive, different from the above. The process is used to obtain a coated, preferably only at the outer surface, hard shell capsule in the pre-locked state, wherein the coating solution, suspension or dispersion has a surface tension of at most 38 mN/m. The polymer-coated hard shell capsule obtained from the process is used for immediate, delayed or sustained release.

Abstract: A polyester is useful as a high viscosity base fluid. A method for its preparation involves isomerizing an alpha-olefin, epoxidizing an internal olefin, reacting an internal epoxide, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.

Abstract: The invention relates to the electrodialytic production of ammonia and sulfuric acid from ammonium-sulfate-rich (waste) waters. An object of said invention was to provide a process for recovering ammonia and sulfuric acid from waters containing ammonium sulfate in high concentrations. The process should be practicable on an industrial scale and have good energy efficiency. This problem is solved by a combination of electrodialysis and water electrolysis. It results in ammonium sulfate being split back into ammonia and sulfuric acid. Unlike conventional three-chamber processes, the process of the invention employs a cell having only two compartments, which can however be multiply parallelized within the stack. This type of scale-up is much more cost-effective than connecting multiple cells in parallel.
