Abstract: A system for targeting information resources that includes a task point value, and a preference vector comprising plural task designators for system performance and a preference allocation associated with each of said plural task designators. The system deducts from the task point value the preference allocation associated with a select one of the plural task designators upon completion of the select one of the plural task designators, to yield a net task point value. The system determines if the net task point value exceeds zero, and directs the system to terminate execution of tasks if the net task point value is equal to or less than zero.

Abstract: A pneumatic conveying apparatus for silage and haylage, including long conveying ducts to carry the air stream with haylage and silage entrained therein. A positive displacement pump produces a flow of significant quantities of air to an air lock. The air lock has a rotor with blades traveling around the cylindrical peripheral wall and end wall defining traveling air lock compartments, the peripheral wall has an opening at its upper portion defining a feed throat receiving silage and haylage from a raised hopper. A high speed rotary impeller rotor at one side of the feed throat propels the silage-haylage into the air lock compartment. The rotor has sharp edged blades wiping along the edges of the air lock rotor blades and a boundary edge of the feed opening of the air lock.
