Abstract: Methods, apparatus, and articles of manufacture to access process control log information associated with process control systems involve obtaining the process control log information from a database based on a plurality of logging time periods and at least one data query. The process control log information is then categorized based on at least one of a plurality of categories. A plurality of output files are then generated based on the plurality of logging time periods and the categorized process control log information. A portion of the process control log information is then retrieved from one of the plurality of output files based on one of the plurality of logging time periods and the portion of the process control log information is output.

Abstract: A milling machine particularly a disc mill for processing cereal seeds and cereal derivatives including a top disc through a central opening in which the material may be fed, and a bottom disc spaced from the top disc, both discs having mutually opposed profiled surfaces and the distance between the discs and the offset of the axes being adjustable to obtain optimum milling of the materials.
