Abstract: Various embodiments described herein relate to systems, software, and methods of utilizing application system configuration packages. Some such embodiments include maintaining a representation of one or more configuration settings of a first set of application functionality in a first package and maintaining a representation of one or more configuration settings of a second set of application functionality in a second package. This embodiment also includes maintaining, in both the first and the second packages, a representation of one or more configuration setting interdependencies between the first and second sets of application functionality.

Abstract: A configuration server includes a configuration repository that stores a wide range of configuration information for possible use by application programs. The configuration repository may include configuration parameters, settings for the parameters, and meta-data of definitions and descriptions of the parameters. Configuration information is selected from the configuration repository and stored in a configuration directory for later use by application programs at runtime. The configuration information is accessed from the configuration directory when needed by an application program or a component thereof.

Abstract: A 90.degree. elbow for pneumatic transport pipes includes a tubular asymmetric cross-sectional expansion at the entrance side, a baffle plate along the outer elbow side and a tubular asymmetric cross-sectional contraction at the exit side of the elbow. The baffle plate is arranged at an angle between about 55.degree. and 65.degree. relative to the incoming flow direction of bulk material. The inner elbow side is defined by a quadrantal pipe shell, with the remaining area being complemented by segments to provide a closed cross section.
