I, RICHARD RIPLEY, of Liverpool, in the County of Lancaster, Manu-
facturing Chemist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PREPARING AND COMPOUNDING ALKALIS AND ACIDS WITH
OTHER SUBSTANCES, AND IN PACKING AND PACKAGES FOR THE SAME, SO AS TO
PREVENT DETERIORATION," to be as follows (that is to say):-
Heretofore it has been the practice in dispensing alkalis and acids in
combination with saccharine or other substances, and flavouring matter
for the making of effervescing draughts, to mix the whole together
and pack the same in single packages for use, and in preparing baking
powders to combine the acids and alkalis with farinaceous matter, and
also to make them up in single packages.

qualities are seriously deteriorated and ultimately entirely destroyed,
thus rendering them comparatively valueless.
Now the object of this Invention is to obviate these objections by
mixing the alkali or alkalis with saccharine or other substances and
flavouring matter, and treating the acids or acids in a like manner, and
then making them up in twin packets or packages of any convenient
description; or two packages, one containing the alkali and the other
the acid, permanently attached together so as to form one packet may
be used, by which arrangement the acids and alkalis are kept apart
until they are required to be. used in combination, when all that is
required is to open both chambers of the packet and discharge the
contents simultaneously into the drinking vessel, then adding the
required quantity of water.
In preparing the acid or acids and the alkali or alkalis for use
as baking powders the acids and alkalis are separately mixed with
farinaceous matter in place of with saccharine and flavouring matter,
and then packed in the manner described as applied to effervescing
draughts.
It is proposed to pack the alkalis and acids with their additions in the
twin or combined packages in the quantities required for single draughts
and single baking powders. Of course the size of the packages may be
regulated by circumstances, but in all cases it is preferred to pack so
much as will be required for use at one time. And in some cases it may
be found desirable to keep separate the acid or acids, alkali or alkalis,
and the flavouring with their additions, when to be used for effervescing
draughts, by placing them in a package having three separate com-
partments, or in three packets attached together so as to form onc, in
which case the saccharine matter or other substances used with the
alkalis and acids may be equally divided amongst the three, or may be
packed in one or two of the three.
Effervescing draughts and baking powders prepared according to
this Invention are peculiarly fitted for exportation or domestic use
after a lengthened period owing to their exceptionally conservative
properties.

page_text: In conclusion it should be remarked that heretofore the ordinary
practice for dispensing acid and alkali for the making of seidlitz and
other like powders has been to put them up in separate papers, and tie
them together with thread, but these form two distinct packages simply
held together temporarily and not permanently attached together as
herein-before described.
