SF6 Gas Recovery from SF6 / N2 Mixtures Using Polymer Abstract. SF 6 gas recovery is considered one of the most important issues when we utilize a gas mixture at a low SF 6 content in gas insulation 1).One of the plausible methods is to recover SF 6 as liquid using the difference in boiling point between gas species in the mixture.

OverviewIn rail transport, track gauge or track gage is the spacing of the rails on a railway track and is measured between the inner faces of the load bearing rails. All vehicles on a rail network must have running gear that is compatible with the track gauge, and in the earliest days of railways the selection of a proposed railway's gauge was a key issue. As the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network. In some places there is a distinction between the nominal gauge and the actual gauge, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, and this device is also referred to as a track gauge. The terms structure gauge and loading gauge, both widely used, have little connection with track gauge. Both refer to two dimensional cross section profiles, surrounding the track and vehicles running on it. The structure gauge specifies the outline into which new or altered structures (bridges, lineside equipment …
