The distributing appliance is actuated by a weighted
cord _H_ attached to the bell _I_ of the gasholder and
discharges at each time a quantity of carbide only sufficient nearly to
fill the gasholder with acetylene. The gas passes from the generator
through the pipe _J_ and seal-pot _D_, or bypass _F_, to
the gasholder. The generating tank is provided with a funnel _G_ for
replacing the water consumed, a sludge-stirrer and a draw-off cock
_L_, and a water-level cock _C_. The gas passes from the
gasholder through a purifier _K_, charged with heratol, to the
service-pipe.

CARBIDE.]
(2) Automatic; carbide-to-water.
The "Debruyne" generator comprises an equalising bell gasholder _A_
placed alongside a generating tank _B_ containing water into which
lump carbide is discharged as necessary from each in turn of a series of
chambers mounted in a ring above the generating tank. The chambers are
removable for refilling, and when charged are hermetically sealed until
opened in turn above the shoot _C_, through which their contents are
discharged into the generating tank. The carbide contained in each
chamber yields sufficient gas nearly to fill the gasholder.
