COMPLETE SPECIFICATION.
An Improved Process of Manufacture of Nitrogenized Water.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co., of
18 Buckingham Street, Strand, W.C., London, Patent Agent, do hereby declare
the nature of this invention a communication to me from abroad by Enrique
Freixa, of Barcelona, in the Kingdom of Spain, Manufacturer, and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
Referring to the drawings annexed, the manufacture is as follows: On the water
contained in a chamber or well A A is placed a floating platform B B supporting
a metal cup or pan C in which is placed refined English phosphorus, over this
apparatus is lowered a bell shaped chamber D D which fits the sides of the
chamber or well and passes through and into the water it contains, constituting
in this manner a hydro-pneumatic apparatus which is furnished with an orifice
made in the upper part of the bell. Through this orifice the phosphorus is lighted
and directly it begins its rapid combustion the orifice is immediately closed and
notice is simultaneously taken of the ascent of the bell through the impulse of the
dilated air consequent on the elevated temperature obtained by the combustion.
The oxygen in the air in the bell is consumed and the organic germs destroyed,
the chemical products are dissolved in the water and the bell contains substantially
only the nitrogen which can be used after about six hours rest. From this
apparatus the nitrogen is passed to various washing flasks H H which contain
solutions of caustic soda, whereby the small quantities of the carbonic and
phosphoric acids which had not been dissolved are eliminated and after repeated
washings in the flasks H H in clean water the nitrogen is drawn out by the pump M
of a saturator.
This pump communicates with a tank N containing filtered and aerated water
and at each stroke of the piston the suction pipes simultaneously draw the
nitrogen and the water to the air compressor R which is provided with a suitable
gauge.
In this compressor the saturation of the water takes place, the pump being
regulated to pump more or less water or nitrogen, these substances are submitted
gradually to a pressure of 18 atmospheres as shown by the pressure gauge, by
which, added to the agitation that the water and the nitrogen experience in the
interior of the compressor by means of a stirrer, a clear and agreeable nitrogenized
water is readily obtained.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
The process of manufacture of nitrogenized water which consists in enclosing a
body of air over water in a well or chamber by means of a bell in the interior of
which is burned phosphorus until all the oxygen in the shut up air in said bell is
expended, there remaining substantially only the nitrogen which is washed and
is then led with distilled water to a compressor in which the nitrogenized water is
produced substantially in the manner illustrated and described.
Dated this 18th day of December 1895.
