摘要:
A computer program product is provided as a system and associated method that allows the user to view a hierarchical lineage in a tree format even in the event of recursive circular relationships. The system prevents the lineage tree from being infinitely expandable truncating tree expansion when encountering a child that has previously appeared in the tree. If the user attempts to expand on an object that leads to a child already displayed in the tree, the system replaces the child's icon with one that resembles a recursive icon. The recursive icon is displayed by the system at the point of recursion, showing that an infinite, recursive relationship has occurred.
摘要:
A mixture producing a slurry for coating metallic vehicle exhaust conduits utilizing a refractory cement and a caustic or alkaline salt binder. Sufficient amounts of water are also employed in the slurry resulting in a flowable material. The slurry flows over and hardens as a thin uniform coating on the interior surface of an exhaust conduit. The coating exhibits excellent adhesion to the metallic material, does not crack or chip under impact forces, and possesses a coefficient of thermal expansion similar to the underlying metallic structure.
