IMPROVEMENTS IN THE CONCENTRATION AND TREATMENT OF SACCHARINE AND SALINE SOLUTIONS, AND IN APPARATUS EMPLOYED THEREIN
Year: 1868

page_text: LETTERS PATENT to Alfred Fryer, of Manchester, in the County of
Lancaster, Sugar Refiner, for the Invention of "IMPROVEMENTS IN
THE CONCENTRATION AND TREATMENT OF SACCHARINE AND SALINE SOLUTIONS,
AND IN APPARATUS EMPLOYED THEREIN."
Sealed the 29th December 1868, and dated the 4th July 1868.
PROVISIONAL SPECIFICATION left by the said Alfred Fryer at the
Office of the Commissioners of Patents, with his Petition, on the
4th July 1868.
I, ALFRED FRYER, of Manchester, in the County of Lancaster, Sugar
Refiner, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE CONCENTRATION AND TREATMENT OF SACCHARINE AND SALINE
SOLUTIONS, AND IN APPARATUS EMPLOYED THEREIN," to be as follows:--
My Invention primarily consists in concentrating and treating
saccharine and saline solutions by bringing into direct contact with them
the gases or products of combustion from a furnace, or in case of some
saccharine solutions the heated carbonic acid gas given off by limestone

page_text: during the process of roasting. The furnace may be of any description
provided the gases or products of combustion therefrom will not injuriously
affect the solutions.
The method in which I prefer to carry my Invention into effect is
as follows: In some cases I pass the gases or products of combustion,
either with or without an admixture of air, between a series of spiral
blades or volutes symmetrically arranged and revolving round a common
centre. The external edges of these blades in their lowest position are
immersed in the solution to be operated upon, and by their revolution
the solution flowing over their surfaces towards the common centre.
preserves the surfaces in a moist state. The heated gases passing over
these moistened surfaces effect the concentration desired. In other cases
pass
the heated gases over other moistened surfaces of any other form
and arrangement. Or, I cause the heated gases to pass through the
reticulations of network, wirework, or perforated plates, the edges of
such reticulations being kept moist by the application to them of the
solution to be concentrated. Or, I cause the heated gases to pass through
a chamber in which the solution to be operated upon is exposed in the
form of drops to their action.
I
Where the gases and products of combustion are used directly for
concentrating purposes, as herein-before described, and especially where
they are used for concentrating the juice of the beetroot, I place limestone
in the furnace or flue in such a way that the carbonic acid contained in
the limestone is driven off and mingled with the products of combustion,
and I bring the carbonic acid mingled with such products into contact
with the juice, and neutralize the alkali contained therein.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Fryer in the Great Seal Patent Office on the
4th January 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
FRYER, of Manchester, in the County of Lancaster, Sugar Refiner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of July, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-

page_text: second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Alfred Fryer, Her special licence that I,
the said Alfred Fryer, my executors, administrators, and assigns, or such
others as I, the said Alfred Fryer, 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 "IMPROVEMENTS IN THE CONCENTRATION AND TREATMENT
OF SACCHARINE AND SALINE SOLUTIONS, AND IN APPARATUS EMPLOYED THEBEIN,'
upon the condition (amongst others) that I, the said Alfred Fryer, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, 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 Alfred Fryer, 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 primarily consists in concentrating and treating
saccharine and saline solutions by bringing into direct contact with them
the gases or products of combustion from a furnace, or in case of some
saccharine solutions the heated carbonic acid gas given off by limestone
during the process of roasting. The furnace may be of any description
provided the gases or products of combustion therefrom will not injuriously
affect the solutions.
The method in which I prefer to carry my Invention into effect is as
follows: In some cases I pass the gases or products of combustion,
either with or without an admixture of air, between a series of spiral
blades or volutes symmetrically arranged and revolving round a common
centre. The external edges of these blades in their lowest position are
immersed in the solution to be operated upon, and by their revolution
the solution flowing over their surfaces towards the common centre
preserves the surfaces in a moist state. The heated gases passing over
these moistened surfaces effect the concentration desired. In other cases
I pass the heated gases over other moistened surfaces of any other forin

page_text: and arrangement. Or, I cause the heated gases to pass through the
reticulations of network, wirework, or perforated plates, the edges of
such reticulations being kept moist by the application to them of the
solution to be concentrated. Or, I cause the heated gases to pass through
a chamber in which the solution to be operated upon is exposed in the
form of drops to their action.
Where the gases and products of combustion are used directly for
concentrating purposes, as herein-before described, and especially where
they are used for concentrating the juice of the beetroot, I place limestone
in the furnace or flue in such a way that the carbonic acid contained in
the limestone is driven off and mingled with the products of combustion,
and I bring the carbonic acid mingled with such products into contact
with the juice and neutralize the alkali contained therein.
In witness whereof, I, the said Alfred Fryer, have hereunto set my
hand and seal, this First day of December One thousand eight
hundred and sixty-eight.
ALFRED FRIER. (L.S.)
