Year: 1854

page_text: LETTERS PATENT' to William Septimus Losh, of Wreay Syke, in the
County of Cumberland, Gentleman, for the Invention of "CERTAIN MEANS
OF DECOLORING RESINS."
Sealed the 17th August 1854, and dated the 8th March 1854.
PROVISIONAL SPECIFICATION left by the said William Septimus Losh
at the Office of the Commissioners of Patents, with his Petition, on the
18th March 1854.
I, WILLIAM SEPTIMUS LOSH, of Wreay Syke, in the County of Cumberland,
Gentleman, do hereby declare the nature of the said Invention for "CERTAIN,
MEANS OF DECOLORING RESINS" to be as follows:-
The Invention consists in acting upon resin with an alkali or alkaline com-
pound in solution in water, which will cause the resin to become blended or
mixed with the solution, and then in subjecting the whole to the action of
sulphurous acid or chlorine gas. The resin separates in the form of flakes
from the solution, in which state I collect, wash, and dry it. When dry, the
resin will be found to be deprived of color either entirely or nearly so, and may
be employed in various arts and manufactures.

by the said William Septimus Losh in the Great Seal Patent Office on
the 4th September 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SEPTIMUS LOSH, of Wreaу Syke, in the County of Cumberland, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of March, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Septimus Losh, Her special licence that I, the said William
Septimus Losh, my executors, administrators, and assigns, or such others
as I, the said William Septimus Losh, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"CERTAIN MEANS OF DECOLORING RESINS," upon the condition (amongst others)
that I, the said William Septimus Losh, by an instrument in writing under
my hand and seal, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Septimus Losh, do hereby
declare the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
My Invention consists in acting upon resin with an alkali or alkaline com-
pound in solution in water, which will cause the resin to become. blended or
mixed with the solution, and then in subjecting the whole to the action of
sulphurous acid or chlorine gas, either separately or conjointly. The resin
separates in the form of flakes from the solution, in which state I collect, wash,
and dry it. When dry, the resin will be found to be deprived of color, either
entirely or nearly so, and may be employed in various arts and manufactures.
And in order to render my process quite clear and easily understood,. I
shall describe the method I employ to put my Invention into practice.

page_text: I take resin and carbonate of soda or potash in the proportions of about
five parts of resin and one part soda or potash, and place them together in a
boiler with about twenty parts of water; I boil them by steam until the resin,
alkali, and water are perfectly mixed. I allow this mixture to cool, and then
pass into such mixture sulphurous acid gas or chlorine gas, or both gases con-
jointly, until the resin separates in white flakes or grains; the whole is then
thrown or run upon a filter, well washed with cold water, and is then, as before
stated, ready to be employed in the arts.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as of my
Invention,
The decoloring of resins (previously subjected to the action of an alkaline
solution) by treating them with sulphurous acid gas or chlorine gas, either
separately or conjointly, in the manner herein-before described.
In witness whereof, I, the said William Septimus Losh, have hereunto
set my hand and seal, this First day of September, One thousand
eight hundred and fifty-four.
WILLIAM SEPTIMUS LOSH.
