A scheduling system and method for moving plural objects through a multipath system described as a freight railway scheduling system. The scheduling system utilizes a cost reactive resource scheduler (340) to minimize resource exception while at the same time minimizing the global costs associated with the solution. The achievable movement plan can be used to assist in the control of, or to automa...

A method of strengthening green form parts made from metal powder requires the use of a cross-linkable polymer which, when cross-linking has been induced, retains its mechanical properties to a degree sufficient to prevent fracture or significant deformation of the green form part when subjected to heat sufficient to induce phase transformation and carbonization. The polymer is incorporated into a...

The method of compacting agglomerated powder comprises the steps of receiving a mass of agglomerated powder of random sizes; separating the mass into at least three distinct range of sizes including a fine range, a medium range and a coarse range; and thereafter compacting the agglomerated powder of each of the ranges into green briquettes, each of which is characterized in having a self-supportin...

A method for use in designing rotary drill bits comprises determining locations in which cutters are to be provided, determining likely wear rates for cutters positioned at those locations, and using the likely wear rates to chose between relatively high and relatively low wear rate cutters for each location. The cutters all have substantially the same impact toughness.

A rotary drill bit includes cutters arranged in a series of concentric rings, the cutters of one of the rings having a different wear resistance to the cutters of another of the rings with the result that the stability of the drill bit improves with wear. Although the wear resistance is different, the cutters have substantially the same impact toughness.
