The gas passes
from the generating chambers _B_ through the pipe _D_ to the
washer-cooler _E_ and thence to the gasholder. From the latter it
passes through the dry purifier _J_ to the service-pipe. The
gasholder bell is sealed in oil contained in an annular tank instead of
in the usual single-walled tank containing water. The purifying material
ordinarily supplied is puratylene. The apparatus is also made to a large
extent in a compact form specially for use on board ships.

_Agents_: FITTINGS, LTD., 112 VICTORIA STREET, S.W.

The "Westminster" generator supplied by this firm is the "Davis"

the sale of this generator in Great Britain are held by this firm.
_Maker_: LOCKERBIE AND WILKINSON, TIPTON, STAFFS.
_Type_: (1) Automatic; water-to-carbide; contact, superposed trays.
The "Thorscar" generator of this firm comprises an equalising gasholder,
the gas-space of the bell _B_ of which is reduced by conical upper
walls. When the bell descends and this lining enters the water in the
tank _A_ the displacement of water is increased and its level raised
until it comes above the mouths of the pipes _E_, through which a
portion then flows to the generators _D_.
