IMPROVEMENTS IN PURIFYING GAS
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
PHILLIPS, of Clist, Honiton, in the County of Devon, Chemist, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Fifteenth day of April, in the eighth year of Her reign,
did, for Herself, Her. heirs and successors, give and grant unto me, the said
Henry Phillips, my exors, admors, and assigns, Her especial licence, full power,
sole privilege and authority, that I, the said Henry Phillips, my exors, admors,
and assigns, or such others as I, the said Henry Phillips, my exors, admiors, or
assigns, should at any time agree with, and no others, from time to time aud at
all times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN PURIFYING GAS;"
in which said Letters Patent is contained a proviso, that I, the said Henry
Phillips, shall cause a particular description of the nature of my said Inven-
tion, and in what manner the same is to be performed, to be inrolled in-Her
said Majesty's High Court of Chancery, within six calendar months next
and immediately after the date of the said in-part recited Letters Patent,
as in and by the same, reference. being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Phillips, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof (that is to say) :-
In the purifying of gas by lime two means are resorted to, called the wet
and the dry lime processes. In some works one only of the two processes is
used; in other works both processes are used consecutively, and the lime
employed for each process (where both are used) is fresh lime.
my
Now, my Invention consists in using for the wet lime process the lime
which has been previously employed for the dry lime process, by which a
considerable saving of lime will result. And in order that
Invention may
be fully understood and readily carried into effect, I will proceed to describe
the means pursued by me, first remarking, that the means and apparatus
employed both for the wet lime process and dry lime process being well
understood, it will not be necessary to describe the same here, and it will only
be necessary in describing my Invention to refer to those processes as well
known processes. In working according to my Invention I first pass the gas
through the wet lime purifiers, and then through the dry lime purifiers. I
employ new or fresh lime in the ordinary manner for the dry lime process,
and having done so, in place of considering the lime when discharged from the
dry lime purifiers (in the ordinary way) no longer suitable for purifying gas, I
cause so much of the lime from the dry lime purifiers as I may require for the
wet process to be immediately mixed with water in a vat, vessel, or other
receivers to prevent it from becoming hard; which lime by means of additional
portions of water I afterwards bring to the proper consistency for the wet
lime process in the same manner as if using fresh lime for such purpose,
and I apply such mixture of lime in the ordinary apparatus used for the wet
lime process.
Having thus described the nature of my Invention, and the manner 'in
which the same is, to be performed, I would have it understood that what I
claim is the mode of purifying gas herein described by applying lime which
has been used for the dry lime process to be then used for the wet lime
-process.
In witness whereof, I, the said Henry Phillips, have hereunto set my
hand and seal, this Sixth day of September, in the year of our. Lord
One thousand eight hundred and forty-five.
HENRY (L.s.) PHILLIPS.
