Abstract: An object oriented framework mechanism for distributing and managing operations of a network application defines classes and class relationships that provide for easily extending the framework to define new heterogeneous operations in a network application. Core functions of the framework mechanism support operation management functions, which may include status reporting, error recovery, scheduling, reexecution of previously-defined operations, persistence of operations, and sharing of operations between users. The framework mechanism provides extensible functions that are extended by a user to define a network application. A network application can thus be defined by a user that supports any or all of the above-mentioned operation management functions without explicitly providing these functions, because these functions are part of the core function of the framework mechanism.

Abstract: The combination stove has a fire chamber that is partially cylindrical including a side loading door for loading wood or other combustible material such as coke or coal into the fire chamber. The front of the stove may be opened to enable viewing of the wood or coal burning in the stove by means of an arcuate sliding door that is operable to substantially totally close the chamber or open a section of the front thereof for viewing purposes. The sliding door is covered by a window construction including a tempered glass face. The stove is provided with an open base for supporting the chamber in a shroud covering the top and back of the chamber, preferably including blower means associated therewith. Particularly for wood combustion, the chamber is provided with a top draft extending longitudinally of the chamber and has supported therein a grate.
