PROVISIONAL SPECIFICATION.
Preventing Gases from Intermingling while Passing Through
Liquids.
JOSEPH BANKS HILLIARD Instrument Maker 65 Renfield Street, Glasgow, does
hereby declare the nature of this invention to be as follows:-
I place suitable, inclined, guiding channels in a tank of liquid (e.g. acid). I
liberate gas at lower end beneath these channels: it travels along them to the
higher end, where it escapes up a tube or other exit, above the surface level of the
liquid. Each set of channels has an independent, separate entrance and exit, so
that different gases may pass through the liquid and be discharged when desired,
without having intermingled. The top of the tank may act as channel for one
gas, while the other gases pass along other submerged channels placed suitably for
them.
My invention is required in many processes, but specially in the making of
chlorine gas; as it enables the chemist to utilize the oxygen in atmospheric air,
during the process, without allowing the other constituents of atmospheric air, to
mix with, spoil, and adulterate the chlorine gas.
Dated this 30th day of December 1893.

Preventing Gases from Intermingling while Passing Through
Liquids.
I, JOSEPH BANKS HILLIARD of 65 Renfield Street, in the County of the City
of Glasgow, North Britain, Surgical Instrument Maker, do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :--
This invention relates to apparatus for preventing gases from intermingling while
passing through and in contact with a liquid, and is applicable to many processes,
but more particularly in the making of chlorine gas, as it allows the chemist to
utilize the oxygen in the atmosphere during the process without allowing the
other constituents of the atmosphere to mix with and spoil or adulterate the
chlorine gas.
In carrying out my invention I provide suitable inclined guiding channels in a
tank containing the liquid, as, for example, acid. I liberate the gas at the lower
end of these channels. It travels along them to the higher end, where it escapes
up a tube or other exit above the surface of the liquid. Each set of channels has
an independent separate entrance and exit, so that different gases may pass through
and in contact with the same liquid, and be discharged when desired without having
intermingled. The top of the tank or vessel may act as a channel for one gas
while the other gases pass along other submerged channels placed suitably for them.
The channels may be attached to the tank, or left unattached, and supported in the
fluid by suitable floats. The channels may be inclined at different angles to
produce different speeds in the passage of the gases.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings in the several
figures of which corresponding parts are marked with the same letters of reference.

page_text: Figure 1 is a longitudinal section of a tank.
Figure 2 is an end view of the same.
Figure 3 is a longitudinal section of a tank with the channels unattached and
supported by floats.
Figure 4 is a cross section of the tank.
Figure 5 is a closed vessel in which the top of the vessel acts as a channel for
one of the gases.
Figure 6 is a cross section of Figure 5.
a a¹ are the channels which are preferably of a semi-circular shape as shown at
Figures 2, 4, and 6. Each channel has an independent pipe 66' attached to its
lower end through which one gas can be introduced to the liquid. The gas passes
along the channel without being allowed to mix with the gases in the other channels
and escapes from the tank by an independent pipe c or c¹. In Figure 3 the
channels a and at and exit and entrance pipes 6 b and c c¹ are supported on the
floats a d².
In Figure 5 one gas is introduced by the pipe to the channels a and passes
along the channels to the exit pipe c, while the other gas enters by the pipe b¹,
passes along the top channels and escapes by the pipe c¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
Apparatus for guiding gases through and in contact with a liquid without
allowing them to intermingle with each other either while in the liquid or after
passing through, substantially as described and illustrated on the accompanying
sheet of drawings.
