PROVISIONAL SPECIFICATION left by the said William John Cooper at the
Office of the Commissioners of Patents on the 29th May 1883.
WILLIAM JOHN COOPER of Westminster Chambers Westminster in the County
of Middlesex Analytical Chemist "IMPROVEMENTS IN THE OBTAINING OF AMMONIA
FROM COAL GAS"
In the manufacture of coal gas as ordinarily carried on there is a considerable
waste of Ammonia at the discharge from the condensers owing to the strength of
the ammoniacal liquor leaving the Condensers-The object of my Invention is to
prevent this waste-To effect this I pass water in as cool a condition as practicable
into the condensers to dilute the Aminoniacal liquor so that it is discharged from
the condensers in such a diluted state or state of reduced strength that practically
it will not yield Ammonia to the atmosphere I may provide any suitable means
for carrying the water to and discharging it into the Condensers for the purpose
described. The quantity of water which will I believe be found most advantageous
in practice is about ten gallons of water for every ton of coal carbonized.

in practice is about ten Gallons of water for every ton of Coal carbonized.
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is :-
The hereinbefore described improvements in the obtaining of Ammonia from
coal gas consisting in passing water into the condensers to dilute the ammoniacal
liquor so that it is discharged from the condensers in such a diluted state or state
of reduced strength that practically it will not yield ammonia to the atmosphere.
In witness whereof I the said William John Cooper have to this my Specifi-
cation set my hand and seal this twenty seventh day of November One thousand
eight hundred and eighty three.
