The two taps are not intended for concurrent use. The
evolved gas passes through a purifier containing any suitable purifying
material to the pipes leading to the burners.
[Illustration: FIG. 56.--"PHOS TYPE E" GENERATOR.]
_Maker:_ ROSCO ACETYLENE COMPANY, BELFAST.
_Type:_ Non-automatic; carbide-to-water
The "Rosco" generating plant made by this firm comprises a generating
tank _A_ which is filled with water to a given level by means of the
funnel-mouthed pipe _B_ and the overflow _O_. On the top of the
water-sealed lid of the generating tank is mounted the carbide feed-valve
_L_, which consists of a hollow plug-tap with handle _M_. When
the handle _M_ is turned upwards the hollow of the tap can be filled
from the top of the barrel with carbide. On giving the tap a third of a
turn the hollow of the plug is cut off from the outer air and is opened
to the generating tank so that the carbide contained in it is discharged
over a distributor _E_ on to the tray _N_ in the water in the
generating tank. The gas evolved passes through the scrubber and seal-pot
_J_ to the storage gasholder _Q_. From the latter the gas
passes through the dry purifier _T_ to the service-pipe.
