From the
gasholder the gas passes through the pipe _J_, with cock _e_,
to the purifier, which is charged with frankoline, puratylene, or other
purifying material, whence it passes to the pipe _N_ leading to the
place of combustion. The generating tank is provided with a sludge-cock
_g_, and a cleaning opening with lid _f_. This generating plant
has been primarily designed for the use of acetylene for autogenous
welding, and is made also mounted on a suitable trolley for transport for
this purpose.

(2) Automatic; carbide-to-water.
A later design of generating plant, known as the Type G, also primarily
intended for the supply of acetylene for welding, has the carbide store
mounted in the crown of the bell of the equalising gasholder, to the
framing of the tank of which are attached a purifier, charged with
frankoline, and a safety water-seal or valve. The whole plant is mounted
on a four-legged stand, and is provided with handles for carrying as a
whole without dismounting. It is made in two sizes, for charges of 5-1/2
and 11 lb. of carbide respectively.
