A New or Improved Fuel Cartridge for Heating Purposes.
I, Dr. AUGUST HERMANN PRINZ, of Baumgarten, near Vienna, in the Empire
of Austria, 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:-
My invention relates to a fuel cartridge for heating purposes and principally
for the quick cooking of liquid and solid food of all kinds either for domestic
use or especially for military purposes.
The annexed drawing Fig. 1 shows a section of a suitable cooking vessel to
use with the said cartridge Fig. 2 the side elevation of the lower part, Fig. 3
a plan of the lower part, Fig. 4 the cartridge.
The cooking vessel consists of the following parts:-
The pot a with cover b to receive the food to be cooked the cover can also be
used a plate, and a combustion chamber forming the lower part ed.
The lower part comprises the sheet mantle c provided in its lower end with
holes for air entrance to the fire, (see Fig. 2) the riveted ring d serves to receive
the pot a.
The bottom of the sheet mantle c is formed by two crossed sheet
strips ef bent on both sides to form supports g to receive the cartridge.
The parts 1 and 2 of the pot can be made of tinned sheet iron or any other
sheet metal. When the cooking vessel is not in use, the lower part is put
in the pot a for better transport. The cartridge h consists of closed tinned or
other sheet metal box containing the combustible. This combustible consists
of alcohol mechanically impregnated with oxygen, and cotton or the like, asbestos,
fossil meal, wood, cellulose, or other suitable absorbent.
The impregnation of the alcohol with oxygen is effected as follows:-
Alcohol is put in an entirely tight steel cylinder or drum constructed to permit
of rotating motion. The alcohol is mixed up with peroxide of barium pulverised,
100 parts of alcohol being mixed with 5 to 10 parts of the pulverised peroxide.
As soon as the alcohol has been put into the steel cylinder or drum and is mixed
with the peroxide, the steel drum is closed and put mechanically in any known
manner into rotation to make 1200 revolutions per minute. This rotation is
to continue for 2 to 3 hours. The peroxide is then allowed to deposit in the
alcohol when the alcohol will have taken up mechanically 5 to 10% of oxygen.
By this mechanical mixing of oxygen into alcohol a mixture is produced which
attains considerably higher temperature in buming than an alcohol without
oxygen. This alcohol mixed with oxygen is absorbed by cotton or the like as
follows:-
-
For burning for 15 minutes, (sufficient to cook tinned or canned meat) 12 CC
of such impregnated alcohol and 1 gram of cotton to suck up this quantity.
To boil 300 grams of beef into beef tea 12 CC alcohol and 10 grams of cotton
suffice.
Instead of barium peroxide pykric acid CHNO, can be used, or the alcohol

page_text: can be treated with peroxide of any metal or metals which at the ordinary
temperature give up oxygen to the water contained in the alcohol.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
-
1. A cartridge for use in cooking purposes consisting of a sheet metal box
containing a combustible composed of cotton or other absorbent material soaked
with a mixture of oxygen and alcohol.
