Year: 1879

page_text: LETTERS PATENT to Carl Kesseler, of 63, Mohrenstrasse, Berlin, W., in the
Empire of Germany, Civil Engineer and Patent Solicitor, for the Invention of
"IMPROVEMENTS IN RECEPTACLES FOR HOLDING MANURES OR OTHER SUB-
STANCES CONTAINING FREE SULPHURIC ACID." Partly a communication from
Paul Friese, Doctor, of Berlin, in the Empire of Germany.
Sealed the 4th November 1879, and dated the 6th May 1879.
PROVISIONAL SPECIFICATION left by the said Carl Kesseler at the Office of
the Commissioners of Patents on the 6th May 1879.

Civil Engineer and Patent Solicitor. "IMPROVEMENTS IN RECEPTACLES FOR HOLDING
MANURES OR OTHER SUBSTANCES CONTAINING FREE SULPHURIC ACID." Partly a
communication from Paul Friese, Doctor, of Berlin, in the Empire of Germany.
The Invention has for its object the preservation of sacks used for the transport
of artificial manure against the injurious action of sulphuric acid, and consists in
steeping the said sacks in aqueous solutions of nitrate of lead, nitrate of calcium, or
acetate of calcium, used either alone or in mixtures, or salts, which when united
with sulphuric acid, give an indissoluble product. Also in steeping the sacks in a
solution of chlorure of barium, mixed with acetate of calcium, whereby muriatic
acid, being set free by the action of the sulphuric acid of the bi-phosphates in the
manure, is combined with lime and acetic acid liberated. The said solutions may
also be supplied with a suitable quantity of binding substance to facilitate the
adhesion of the salts to the vegetable fibres of the sacks, after the water has been
evaporated.

the said Carl Kesseler in the Great Seal Patent Office on the 4th November
1879.
CARL KESSELER, of 63, Mohrenstrasse, Berlin, W., in the Empire of Germany,
Civil Engineer and Patent Solicitor. "IMPROVEMENTS IN RECEPTACLES FOR HOLDING
MANURES OR SUBSTANGES CONTAINING FREE SULPHURIC ACID." Partly a commu-
nication from Paul Friese, Doctor, of Berlin, in the Empire of Germany.
The Invention has for its object the preservation of sacks used for the transport
of artificial manure against the injurious action of sulphuric acid, and consists in
steeping the said sacks in aqueous solutions of nitrate of lead, nitrate of calcium,
acetate of lead, or acetate of calcium, or their chemical equivalents, used either alone
or in mixtures, which salts when united with sulphuric acid give an indissoluble
product. Also in steeping the sacks in a solution of chloride of barium mixed with
acetate of calcium, whereby muriatic acid, being set free by the action of the
sulphuric acid of the superphosphates in the manure, is combined with lime and
acetic acid liberated. The said solutions may also be applied with a suitable quantity
of binding substance to facilitate the adhesion of the salts to the vegetable fibres of
the sacks, after the water has been evaporated.
Claim. The method of treating or manufacturing receptacles or sacks for holding
and transporting manures, substantially for the purposes and in the manner set forth
and described.
In witness whereof, I, the said Carl Kesseler, have hereunto set my hand and
seal, this First day of November, A.D. 1879.
