Improvements in the Preparation, Packing, and Storing of
Photographic Chemical Compounds.
We, JAMES RANDOLPH COURTENAY GALE, 3 Egmont Road, Sutton, Surrey,
M.A. and JAMES WILLIAM THOMAS CADETT, Ashtead, Surrey, Photographic
Chemist, do hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in the preparation, packing and storing of
photographic chemical compounds, and has for its object the concentration, for the
sake of preservation and portability, of chemical substances, such as quinol,
pyrogallol, potassium, metabisulphite, and the like, or of any compounds of them,
or of any of them, used for the production and development of photographic
images.
Such invention consists in beating or mixing, or beating and mixing one or more
of such chemical substances with sufficient water, or other suitable medium or
media, and either with or without the aid of heat, so as to produce a semi-finid
composite mass or paste, which can be easily packed and stored in either small or
large quantities, in suitable receptacles of any convenient size and shape, so as to
preserve the same in a condition ready for immediate use, and so that by adding
an adequate proportion of such semi-fluid composite mass or paste to any suitable
fluid, the required solution is produced almost instantaneously; this being a very
considerable advantage, and one which under the methods at present adopted for
producing such solutions is unobtainable.

Improvements in the Preparation, Packing, and Storing of
Photographic Chemical Compounds.
We JAMES RANDOLPH COURTENAY GALE, 3 Egmont Road Sutton, Surrey,
M.A. and JAMES WILLIAM THOMAS CADETT Ashtead, Surrey, Photographic
Chemist do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
Hitherto great difficulty and inconvenience have been experienced in preparing
packing and storing certain chemical compounds and substances used for the
production and development of photographic images on account of the limited
solubility of such chemical compounds and substances. Among such chemical
compounds and substances may be mentioned quinol, potassium metabisulphite and
others.
Our present invention relates to an improved process and method of preparing
packing and storing such chemical compounds or substances and has for its object to
obviate the disadvantages above referred to by concentrating and storing the same

page_text: so as to preserve the essential qualities thereof unimpaired and at the same time to
admit of their being packed in a highly convenient for:n, whereby they are
rendered extremely portable and are ready for immediate use.
Such invention consists in taking the requisite chemical substances and mixing
them together in suitable proportions with a sufficient quantity of water, glycerine,
gum, gelatine or other suitable medium or media, (such quantity being determined
by the particular substances under treatment) and stirring or beating the mixture
thus produced until it assumes the consistency of paste or cream, in which form it
can be readily packed in either small or large quantities in suitable receptacles
of any convenient size and shape so as to preserve the same in a condition ready
for immediate use, as by adding an adequate proportion of such paste or cream to
a suitable quantity of water or other suitable solvent the required solution is
obtained.
In preparing such paste or cream the component ingredients or substances may
be treated either with or without the aid of heat as may be found most desirable
the employment of such auxiliary aid being determined by the nature of the
particular substances under treatment.
We wish it to be clearly understood that we make no claim to the particular
substances or ingredients employed, the features of novelty of our invention
consisting in the particular method of blending or mixing such substances together
so as to produce a paste or cream in the manner hereinbefore described and in
packing and storing the same in suitable receptacles so as to preserve the essential
qualities of the mixture and thus render it ready for immediate use. In order
that our said invention may be better understood we subjoin the following formula
as an illustration thereof. Take two parts of quinol, two parts of potassium
metabisulphite and one part of potassium bromide and grind the same together in
a suitable vessel; then aid sufficient water thereto taking care to continue to grind
or stir the same until a paste or cream is formed. Heat may be used as an aid
to the mixing or solution of the substances the stirring being continued until the
mixture assumes a pasty or creamy consistency while cooling.
Should there be any tendency to precipitation, glycerine, gum or the like may be
added in sufficient quantity to counteract such tendency.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is.
Taking any chemical compounds or substances suitable for developing the
photographic image and mixing them together either with or without the aid of
heat with a sufficient quantity of water, glycerine, gum, gelatine or other suitable
medium or media (such quantity being determined by the particular substances
under treatment) and then stirring and beating the mixture thus produced until it
assumes the consistency of a paste or cream and packing and storing such paste or
cream in suitable receptacles of any convenient size and shape so as to preserve
the same in a condition ready for immediate use all substantially as hereinbefore
described.
