IMPROVEMENTS IN THE PRODUCTION OF SACCHARATE OF LIME
Year: 1877

page_text: LETTERS PATENT to John Henry Johnson, of 47, Lincoln's Inn Fields, in the
County of Middlesex, Gentleman, for the Invention of "IMPROVEMENTS IN
THE PRODUCTION OF SACCHARATE OF LIME" A communication from abroad
by Doctor Augustus Seyferth, of Brunswick, in the Empire of Germany.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson at
the Office of the Commissioners of Patents on the 8th December 1877.
JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman. IMPROVEMENTS IN THE PRODUCTION OF SACCHARATE OF LIME."
A communication from abroad by Doctor Augustus Seyferth, of Brunswick, in
the Empire of Germany.
This Invention has for its object the production of saccharate of lime or molassate
of lime of a porous and friable texture, capable of being economically applied for
various purposes in the production and refining of sugar.
In carrying out this Invention molasses (or other saccharine products) of low
quality are taken and rapidly mixed with finely divided anhydrous caustic lime.
This mixing is effected in a pug mill similar to that used in the manufacture of
ordinary superphosphate, and during the said mixing little, if any, visible action
takes place.
The apparently fluid mass is then run into a receiving tank, when, after the lapse
of a few minutes, a violent action commences, the lime being slaked by the water of
the molasses, and entering into combination with the sugar to form a saccharate of
lime of a highly porous and friable character; this process is far more rapid and
simple than those ordinarily employed, whilst the product obtained is suitable for
purposes for which the ordinary form of saccharate of line cannot conveniently be
used.

JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman "IMPROVEMENTS IN THE PRODUCTION OF SACCHARATE OF LIME"
A communication from abroad by Doctor Augustus Seyferth, of Brunswick, in the
Empire of Germany.
The said Invention has for its object the production of saccharate of lime or
molassate of lime of a porous and friable texture, capable of being economically
applied for various purposes in the production and refining of sugar.
In carrying out the said Invention, molasses or other saccharine products, by
preference of low quality, are taken, and are rapidly mixed with finely divided
anhydrous caustic lime, in sufficient quantity to combine with the sugar contained
in the molasses or saccharine products or solutions to be acted upon. This mixing
may be effected in a pug mill, similar to that used in the manufacture of ordinary
superphosphate of lime, or otherwise constructed, during the said mixing little, if any,
visible action takes placo.
The apparently fluid mass or the result of this admixture is then run into a
receiving tank, when, after the lapse of a few minutes, a violent action commences,
the he being slaked by the water contained in the molasses or other saccharine
products or solutions, and then entering into combination with the sugar, so as to
form a saccharate of lime of a highly porous and friable character; this process is
far more rapid and simple than those ordinarily employed, whilst the product
obtained is suitable for purposes for which the ordinary form of saccharate of lime
cannot conveniently be used.
Having now described and particularly ascertained the nature of the said Inven-
tion, 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 herein-before in pait recited
Letters Palent is, the production of saccharate of lime by intimately combining
anhydrous caustic lime in a fine state of division with molasses or other saccharme
solutions or products, by preference of low quality, substantially in the manner
herein-before described.
In witness whereof, I, the said John Henry Johnson, have to this my
Specification set my hand and seal, the Seventh day of June, One
thousand eight hundred and seventy-eight.
J. HENRY JOHNSON.
