- n. A valve in a gas-main arranged so as to dip into water or tar, and thus form a seal; a seal-pipe.
Sorry, no etymologies found.
The gas evolved passes from each generating chamber through a pipe _L_, terminating in the dip-pipe _M_, which is provided with a baffle-plate having very small perforations by which the stream of gas is broken up, thereby subjecting it to thorough washing by the upper layers of water in the gasholder tank.
Into this trough, which is filled with water, a dip-pipe or scoop attached to the bottom of the tender of the running train is lowered; and, at a speed of 50 miles an hour, as much as 1070 gallons of water are scooped up in the course of a few minutes.
