Improvements in the Generation of Motive Power.
We, CARLO GUATTARI of 70, Milkwood Road, Herne Hill, S.E. Engineer,
and THE GUATTARI POWER SYNDICATE LIMITED of 16, St. Helen's Place, in
the City of London, do hereby declare the nature of this invention to be as
follows:--
This invention relates to an improved method of generating motive power from
carbonic acid gas in combination with reagents whereby the pressure required for
motive purposes is generated in such a way that the objections incidental to the
use of carbonic acid gas in the compressed or liquid form do not arise, the gas
being moreover used over and over again repeatedly.
The carbonic acid gas is generated in the usual way at atmospheric pressure,
washed, passed through alcohol and supplied to a reservoir containing water,
alcohol, and hydrochloric acid wherein it becomes absorbed or dissolved. The
liquid holding the gas in solution is pumped into a boiler fired in the usual way
and provided with a sight-feed device through which Dutch liquid (ethene
chloride) is supplied in regulated quantities to the boiler. By the reaction of the
carbonic acid solution and of the Dutch liquid under heat a mixture of steam and
gases at high pressure is flashed out, which is then passed through a reducing
valve to the engine cylinders. The engine exhausts into a coil or other form of
surface condenser which is cooled by a solution of ether and chloroform in water
into which carbonic acid gas is injected from time to time whereby a refrigerating
effect is produced corresponding to from-90 degrees C. to-100 degrees C. the
condensed product being returned to the main reservoir for use over again in the
boiler.

Improvements in the Generation of MOLIVE
We, CARLO GUATTARI of 70, Milkwood Road, Herne Hill, S.E. Engineer,
and THE GUATTARI POWER SYNDICATE LIMITED of 16, St. Helen's Place, in
the City of London, 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 has for its object to lessen the consumption of fuel in the
generation of motive power by the employment in the boiler of water impregnated
with a compound of carbonic acid gas whereby the generation of pressure is
rendered possible with an expenditure of heat energy very much below that by
which it would be possible to generate steam in the ordinary way. The use of

page_text: carbonic acid gas alone for this purpose would not however be practicable as the
gas would be quickly driven off from the water on the application of heat with
the result that the gas would become lost and the water be left in its natural
condition.
The invention consists essentially in the addition to the water of a compound
resulting from the combination of carbonic acid gas and a re-agent whereby the
separate evolution of the carbonic acid gas is prevented and the condensation of
the combined gases and vapours after doing work is rendered possible without
loss. This re-agent is ethene chloride, commonly known by the name of Dutch
liquid, and the method of operating, which will be described with reference to the
accompanying diagram, is as follows:-
The carbonic acid gas is generated in the ordinary way in a suitable closed
receiver A provided with an agitator, the receiver containing a carbonate in
suspension in water to which hydrochloric or sulphuric acid is added from a
receiver B, the receiver A being provided with a stoppered mouth at which
the ethene chloride is introduced. The proportions which are found suitable
are:-
Water
Whitening
Acid
Ethene chloride
28 litres
7 kilogrammes
2 litres
- 140 grammes
From
but we do not limit ourselves in this respect. From the gas-generating vessel A
the resulting compound gas passes off through a pipe a (provided with a check
valve) and is injected through a perforated pipe 6 into a saturator being a closed
receiver C filled with water to be saturated with say two or three times its own
volume of the compound gas at the pressure at which it was generated, that is to
say without being first compressed or liquefied. From the saturator C the
solution or water now charged with the compound gas, is drawn by the feed
pump D and supplied to any ordinary boiler E fired in the usual manner.
the boiler the combined steam and gases therein evolved are supplied to an
engine K and after doing work therein are exhausted into a surface condenser F
of any suitable construction cooled by water in the ordinary way wherein
condensation takes place without separation of gas, and from which the condensed
solution or water still charged with gas is extracted by an air pump G and
delivered to a receiver H (which may be open to the atmosphere) from whence it
is drawn by any suitable steam pump I and returned to the receiver C for use
again.
The cycle above described may be repeated over and over again continuously
for any required number of hours, it being only necessary to repeat the operation
of geuerating the compound of carbonic acid and ethene chloride in receiver A
as often as may be necessary to make up for unavoidable loss.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The herein described improvement in the generation of motive power which
consists in generating pressure by the evaporation in a boiler of water impregnated
with carbonic acid gas in combination with Dutch liquid or ethene chloride
substantially as specified.
