Abstract: Systems and methods that select a cache flushing algorithm are provided. A stripe that spans multiple storage devices and includes a plurality of segments is provided. The stripe also includes dirty data stored in a picket-fence pattern in at least a subset of segments in the plurality of segments. A memory cache that stores data separately from the plurality of storage devices and a metadata cache that stores metadata associated with the dirty data are also provided. A cache flushing algorithm is selected using the metadata. The selected cache flushing algorithm flushes data from the memory cache to the stripe.

Abstract: A method to recover wax from wax patterns used in investment casting using a lost wax technique without damaging incorporated ceramic cores is disclosed that includes subjecting the wax pattern to specific conditions. These conditions include chilling a casting tool including the wax pattern and ceramic cores such that a brittle transition temperature for the wax material is approached. Once chilled the wax pattern is subjected to brittle fracture release of the wax from the underlying ceramic cores without damage to those cores.

Abstract: In order to recover wax from wax patterns used in investment casting using a lost wax technique without damaging incorporated ceramic cores, the present method comprises subjecting the wax pattern to specific conditions. These conditions essentially chill a casting tool comprising the wax pattern and cores such that a brittle transition temperature for the wax material is approached. Once chilled the wax pattern is then subject to brittle fracture release of the wax from the underlying ceramic cores without damage to those cores.
