Year: 1809

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, PHILLIPS
LONDON the elder, and PHILLIPS LONDON the younger, of the Parish of Saint
Luke, Chelsea, in the County of Middlesex, Gentlemen, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, on or about the Nineteenth day of April, in the forty-ninth year of
His reign, did give and grant unto us, the said Phillips London the elder,
and Phillips London the younger, our executors, administrators, and assigns,
His special licence, full power, sole privilege and authority, that we, the said
Phillips London the elder, and Phillips London the younger, our executors,
administrators, and assigns, during the term of fourteen years therein expressed,
should and lawfully might make, use, exercise, and vend the Invention therein
mentioned, to wit, "CERTAIN NEW AND IMPROVED METHODS OR PROCESSES OF MANU-
FACTURING, REFINING, AND PURIFYING MURIATE OF SODA OR COMMON SALT," within
that part of the United Kingdom of Great Britain and Ireland called England,
the Dominion of Wales, and Town of Berwick-upon-Tweed, in such manner
as to us, the said Phillips London the elder, and Phillips London the younger,
our executors, administrators, and assigns, or any of then, should seem meet,
to have, hold, exercise, and enjoy the said licence, powers, privileges, and
advantages therein granted unto us, the said Phillips London the elder, and
Phillips London the younger, our executors, administrators, and assigns, for
and during and unto the full end and term of fourteen years from the date of
the said Letters Patent next and immediately ensuing, and fully to be com-
plete and ended according to the Statute in such case made and provided; in

page_text: we,
which said Letters Patent there is amongst other things contained a proviso,
that if
the said Phillips London the elder, and Phillips London the younger,
or one of us, should not particularly describe and ascertain the nature of our
said Invention, and in what manner the same is to be performed, by an instru-
ment in writing under our hands and seals, or under the hand and seal of
one of us, and cause the same to be inrolled in the High Court of Chancery
within six calendar months next and immediately after the date of the said
Letters Patent, that then the said Letters Patent, and all liberties and advan-
tages whatsoever thereby granted, should utterly cease, determine, and become
void, as in. and by the said recited Letters Patent, reference being thereunto
had, will more fully appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Phillips London the elder, and Phillips London the younger, do hereby describe
and ascertain the nature of our, said Invention, and the manner in which the
same is to be performed, as follows, that is to say:
It consists in purifying, refining, and manufacturing muriate of soda or com-
mon salt for general use and purposes, viz:-Rock or fossil salt, salt made
from rock or fossil salt, or from brine springs, sea water, or muriato of soda or
common-salt, in any state, or however made or obtained, by fusion or by heat,
or calcination, and by the application to it (or its solution) of soda (mineral
alkali), its nitrate, sulphate, or carbonate, or any other of its combinations,
potash (vegetable alkali), volatile alkali, lime, or their sulphates, nitrates,
carbonates, or any other of their combinations, or-by the addition of any other
material or re-agents that will effect the decomposition, precipitation, or sepa-
ration of the whole or part of the earths and metals, or earthy or metallic salts
mixed with or combined with the muriate of soda or common salt, which
re-agents and materials, or any of them, we apply at any time, or part of the
processes herein-after mentioned, to the muriate of soda or conimon salt before
mentioned, or any solution thereof, as particular circumstances may suit or
require. The muriate of soda or common salt (with the necessary re-agents and
materials) is to be put into a reverberatory furnace or furnaces, or any suitable
furnaces, kilns, pots, pans, or other fit and proper vessel or vessels, and such a
degree of heat applied as will fuse the said muriate of soda or common salt, (at
this period of the process the re-agents and materials may be applied if preferred,)
which being kept in fusion-a-sufficient time, so that the earthy and metallic
parts be decomposed, precipitated, or separated, is to be drawn off or taken
out into proper receiving vessels as long as it continues to conie off fit and
clear, (or it may remain to cool in the furnaces, kilns, &c.,) leaving the sediment
or residue of the precipitated or separated earths and metals with some muriate

page_text: of soda or common salt in the furnaces, kilns, &c.; afterwards the muriate of
soda or common salt may be broken for use into any size grains or pieces
required. But if the muriate of soda or common salt be not required in a state
of such purity as it may be procured by the aforesaid means, it may be fused, as
above, with some or without any of the said re-agents or materials, as by a
properly regulated and continued heat part of the earthy and metallic salts will
be decomposed or separated, and the earths and metals precipitated or soparated,
and the muriate of soda or common salt be drawn off or taken out, &c., as
aforesaid. The muriate of soda or common salt remaining with the sediment
or residue in the furnaces, kilus, &c., we entirely recover by solution and
evaporation, and when the earthy and metallic salts, mixed with or combined
with the muriate of soda or common salt, are of the kinds capable of being
decomposed or separated by calcination or by a considerable degree of heat,
and the muriate of soda or common salt be not required in such purity or in
very large pieces or grains, as is obtainable by fusion, heat, or calcination, need
only be employed. In which case the muriate of soda or common salt may be
taken out of the furnaces, kilns, &c. for use, or may be refined by the modes
usually practised with rock salt, viz, by solution, deposition, and evaporation,
which mode is also applicable to salt having been fused, and the muriate
of soda or common so refined will be purer and more fit for curing fish,
and provision, and common use, than any small salt at present manufactured.
The muriate of soda or common salt manufactured by the aforesaid process or
processes may be generally used, and it is presumed that the muriate of soda
or common refined by fusion may supercede the necessity of importing or using
any foreign bay salt altogether.
In witness whereof, we, the said Phillips London the elder, and Phillips
London the younger, have hereunto set our hands and seals, this
Ninth day of October, in the year of our Lord One thousand eight
hundred and nine.
