A modular, aerogel-based vacuum insulated pipe section comprising an outer conduit; an inner conduit concentrically disposed within the outer conduit with aerogel insulation and a condensable gas being disposed in the insulation space between the concentric conduits. As a stand-alone pipe section, the insulation space is at a pressure within the range of from about 100 microns Hg to about 1000 microns Hg. However, in operation, when a cryogenic fluid is traversing the inner conduit, the condensable gas condenses and the pressure within the insulation space is further reduced to range of from about 1 microns Hg to about 5 microns Hg. The vacuum insulated pipe section further includes a coupling arrangement disposed on a first end of the inner conduit and a second end of the inner conduit, the coupling arrangement configured to engage or mate with a corresponding end of another modular vacuum insulated pipe section.

A multi-component fluid delivery system includes a first fluid pump and a second fluid pump. The first and the second fluid pumps are not mechanically coupled to each other. The multi-component fluid delivery system further includes a control system comprising a processor configured to derive a slip ratio for the first fluid pump and the second fluid pump. The processor is additionally configured to apply a master-slave motor control to deliver a specified fluid ratio via the first and the second fluid pumps based on the slip ratio.

The presently disclosed technology is directed toward the removal of plugs in a pipeline segment by installing one or more clamping devices onto a pipeline. The clamping device will have the ability to access the inside of the pipeline segment and inject media designed to dissolve the plug.

A coaxial hose for electrostatic oiling systems that includes a flexible external tube, and a flexible internal tube for the circulation of a second fluid inside thereof. The internal tube together with the external tube form an annular space for the circulation of a first fluid. The internal tube includes an internal layer made of PTFE that is intended to contain the second fluid, internal braiding that is intended to lend the internal tube pressure resistance and an external layer that is made of polyamide material which is intended to prevent the passage of the first fluid through the braiding.

To generate a checkpoint for a virtual machine (VM), first, while the VM is still running, a copy-on-write (COW) disk file is created pointing to a parent disk file that the VM is using. Next, the VM is stopped, the VM's memory is marked COW, the device state of the VM is saved to memory, the VM is switched to use the COW disk file, and the VM begins running again for substantially the remainder of the checkpoint generation. Next, the device state that was stored in memory and the unmodified VM memory pages are saved to a checkpoint file. Also, a copy may be made of the parent disk file for retention as part of the checkpoint, or the original parent disk file may be retained as part of the checkpoint. If a copy of the parent disk file was made, then the COW disk file may be committed to the original parent disk file.

A heat exchanging to exchange heat between a first fluid and a second fluid has a thermally conductive conduit with a double wall construction with an inner wall and an outer wall fixed thereto and defining a plurality of leak channels therebetween. Any fluid entering the leak channels is conveyed and detected to indicate a potential breach of the inner wall or outer wall. One of the fluids may be warm waste water and the other fluid may be clean water under pressure to recover heat from the waste water. An interleaving baffle located in the fresh water conduit increases heat transfer.
