I, JOHN CLAYTON MEWBURN, of the Firm of J. C. Mewburn & Ellis, of 55
and 56, Chancery Lane, London, Chartered Patent Agents, do hereby declare
the nature of the said invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:-
This invention relates to the employment and administration of vanillin.
The perfume vanillin exists either as a constituent of the vanilla pod, which
is a natural product, or it may be produced artificially by any known processes.
The vanilla pod contains at most 2 per cent. of pure vanillin. This perfume
has, however, such an intense effect, that its use is rendered difficult, for the reason
that the requisite doses or quantities are too small. In order to facilitate the use
of vanillin, the latter has consequently been brought into dilute solution by means
of alcohol, or it has been mixed with an abundance of sugar, with the object of
thus obtaining doses or regulated quantities containing a determined strength of
vanillin.
But even in the form of these solutions and mixtures, vanillin has not been
able to replace the vanilla pod to any appreciable extent.
According to the present invention, the vanillin is formed into solid portions of
any desired determined percentage. By the statement of how many of these
portions (say 1 to 25 in number) are equivalent to the vanillin percentage of a
medium-sized vanilla pod the employment of vanillin is very considerably
facilitated. For this purpose vanillin is mixed with a neutral powder,
such for example as flour or sugar, or carbonate of soda and the like and
from this mixture solid pieces are formed by pressing or moulding. The pieces
are made of such a size that each piece shall have the same percentage of vanillin,
and that a desired number of the pieces (say 1, or 2, or 3, or 4, or 5 &c.) shall
contain a percentage of vanillin equal to that contained in a medium-sized vanilla
pod.
The solid pieces may be pressed or moulded in any desired shape of a round,
oval or angular tablet, of a rod, of a cube, of a pill, or of any other form.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me and in what manner the same is to be performed,
I declare that what I claim is:-
1. Improvements in the employment of vanillin, consisting in mixing vanillin
with an indifferent powder and forming the mixture by pressing or moulding into
solid portions or pieces, any determined number of which is equivalent to the
amount of vanillin contained in a vanilla pod.

page_text: 2. As a new product, a tablet, pill or the like containing vanillin mixed with
an indifferent powder (such for example as flour or sugar), said tablet or the like
containing a definite percentage of vanillin.
Dated this 21st day of February 1898.
