Abstract: An apparatus and method for centralized policy management of large-scale networks (221) of computational devices is disclosed. The apparatus includes a number of distributed clients (400) run on registered computers (201-203), gathering policy advisories (401) and reporting (405) relevance (403) to a system administrator (224). The system administrator may view the relevant messages (505) through a management interface (500) and deploy suggested actions to distributed clients (503), where the actions are executed to apply the solutions of the advisories (408).

Abstract: The invention disclosed herein enables a collection of computers and associated communications infrastructure to offer a new communications process which allows a requestor to receive configuration information of a computational device from a responder. The requester first sends query documents that contain queries for configuration information of a computational device to the responder; the responder automatically collects the answers for the queries and sends a response document that contains the configuration information of the computational device to the requestor. The queries are written in a formal descriptive language which is transparent, safe for network evaluation, and extensible, and the configuration reader of the responder can parse the queries and automatically invoke a set of standard inspectors to obtain the corresponding configuration information.

Abstract: The present invention is a method to determine the chemical concentration of one or more of a number of the constituent classes of a feed to a catalytic cracking process. These constituent classes which are referred to as "lumps", include 14 different molecular types in 4 different boiling range fractions. A specific lump will include all individual molecular components which are expected to react in a similar way in the catalytic cracking unit.

Abstract: A metering and delivery system for feeding finely powdered coal to a combustion chamber includes a hopper containing finely ground coal, a vertical feed pipe extends from the hopper and a horizontal metering conduit is connected to the lower end of the feed pipe so that the coal provides a surface of repose in the metering conduit below an air flow opening with a bleed opening being downstream of the air flow opening. A venturi jet housing provides suction on the metering conduit drawing ambient air into the openings to entrain coal for injection by an injector lance into a combustion space. Metering of the coal is provided by inversely operated valves through which ambient air flows to the openings in the metering conduit.
