Abstract: A device for accumulating, isolating, indicating and venting accumulated gas in a fluid system pipe includes a main pipe fitting affixed to a system pipe in which a hole has been drilled. A standpipe attached to the pipe fitting houses a magnetic float. A magnetic-float level indicator exterior to the pipe indicates the magnetic float's level.

The expansion tool is moved along a path inside the host pipe, stopping at stations on the way.

Abstract: A bridge comprises a first inlet port, a second inlet port, an outlet port, and a chamber for silicone oil. The oil is density-matched with the reactor droplets such that a neutrally buoyant environment is created within the chamber.

The introduction of a second droplet from the second inlet port causes the formation of an unstable funicular bridge that quickly ruptures from the, finer, second inlet port, and the droplets combine at the liquid bridge. In another embodiment, a droplet segments into smaller droplets which bridge the gap between the inlet and outlet ports.
