PROVISIONAL SPECIFICATION.
Improvements relating to Gas Cartridges.
I, WILHELM OCHSE, Doctor of Philosophy, of 46 Hohe Strasse, Cologne, in
the German Empire, do hereby declare the nature of this invention to be as
follows:-
The application of explosive gases and especially oxyhydrogen gas, for blasting
purposes, has hitherto met with two serious obstacles, that is the small specific
gravity and large volume of the gases, and in case their volume is reduced by
compression the great volubility of these gases, which rendered leakage through
stoppering or closing devices of receptacles almost or quite inevitable.
In order to avoid these evils, I form the cartridge of a completely closed
cylindrical vessel, containing a small quantity of liquid, from which the required
explosive gas mixture may be produced by chemical or electric action.
In the case of oxyhydrogen, this liquid may be acidulated water.
The accompanying drawing is a section of a cartridge a partly filled with liquid c,
and provided at the lower end with a pair of electrodes b, b, passing (gas tight)
through the walls of the vessel into the liquid.
The gas required for blasting is produced in the cartridge itself by decomposing
the liquid contained in it, either chemically or by means of an electric current
introduced through the electrodes b.
The gas thus produced will be subject to its own pressure and therefore at a high
density.
For igniting the gas mixture, an electric spark is caused to pass between the
electrodes.
Instead of oxyhydrogen, other explosive gas mixtures may be formed in such
cartridges.

Improvements relating to Gas Cartridges.
1, WILHELM OCHSE, Doctor of Philosophy, of 46 Hohe Strasse, Cologne, in
the German Empire, 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 aud by the following statement :-
The application of explosive gases and especially oxyhydrogen gas, for blasting
purposes, has hitherto met with two serious obstacles, that is the small specific
gravity and large volume of the gases, and in case their volume is reduced by
compression the great volubility of these gases, which rendered leakage through
stoppering or closing devices of receptacles almost or quite inevitable.
In order to avoid these evils, I form the cartridge of a complete closed cylindrical
vessel, containing a small quantity of liquid, from which the required explosive gas
mixture may be produced by chemical or electric action.
In the case of oxyhydrogen, this liquid may be acidulated water.

page_text: In the drawing filed with the Provisional Specification is shown a section of
a cartridge a partly filled with liquid e, and provided at the lower end with a pair
of electrodes b, b, passing through the walls of the vessel into the liquid.
The gas required for blasting is produced in the cartridge itself by decomposing
the liquid contained in it, either chemically or by means of an electric current
introduced through the electrodes b.
The gas thus produced will be subject to its own pressure and therefore at a high
density.
For igniting the gas mixture, an electric spark is caused to pass between the
electrodes.
Instead of oxyhydrogen, other explosive gas mixtures may be formed in such
cartridges.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
A cartridge for blasting purposes consisting of a closed vessel a containing a
liquid capable of decomposition into an explosive gas, and electrodes for igniting
the said gas by the passage of an electric spark, substantially as and for the purpose
herein described.
Dated this 15th day of September 1894.
