Abstract: Systems include one or more critical datacenter connected to behind-the-meter flexible datacenters. The critical datacenter is powered by grid power and not necessarily collocated with the flexboxes, which are powered “behind the meter.” When a computational operation to be performed at the critical datacenter is identified and determined that it can be performed at a lower cost at a flexible datacenter, the computational operation is instead routed to the flexible datacenters for performance. The critical datacenter and flexible datacenters preferably shared a dedicated communication pathway to enable high-bandwidth, low-latency, secure data transmissions.

Abstract: A compressor housing having an integrally formed throat, such as is used on internal combustion engines and specifically diesel engines, may be repaired or modified by removal of the throat portion and replacement of that portion with a separate throat insert selected from a variety of throat inserts for a given size compressor housing and for various specifications.

Abstract: A compressor housing (30) is disclosed of the type characterized by having a centrally-disposed, concentric, flow restricting inlet throat in fluid communication with an encircling fluid conduit having a tangentially disposed outlet. Compressor housing (30) includes a separately formed inlet throat insert (45) for being positioned in a bore (29) in compressor housing (30). Insert (45) can be removed if damaged, or if a change in inlet throat size is desired.
