A dissolved air flotation system and method for purifying fresh water. The system is self-contained within a standard shipping container, with all components disposed in-line within the shipping container. Float is removed from the flotation tank with a skimmer that drives float downstream onto a conveyor belt, and the conveyor belt conveys float away from the flotation tank, in the downstream dir...

A method and apparatus for thermoforming deep drawn parts such as cups in which a vacuum is momentarily applied to a preheated sheet material when overlying a clamping plate prior to clamping and advance of the plug assists to delay contact with a lip molding feature projecting from each mold cavity. This avoids a molding defect due to premature cooling of a localized region of the sheet material ...

A high-speed routing search is realized by a hierarchical routing table, while a conventional network having a hierarchical network as a backbone performs conventional operations without being aware of the hierarchical backbone network, in a mixed environment of the hierarchical and non-hierarchical networks, by assigning the non-hierarchical network a virtual hierarchy number equivalent to a hier...

A computer implemented cache memory for a RAID-5 configured disk storage system to achieve a significant enhancement of the data access and write speed of the raid disk. A memory cache is provided between the RAID-5 controller and the RAID-5 disks to speed up RAID-5 system volume accesses. It utilizes the time and spatial locality property of parity blocks. The memory cache is central in its physi...
