PROVISIONAL SPECIFICATION left by the said Samuel Henry Hinde at
the Office of the Commissioners of Patents on the 25th May 1881.
SAMUEL HENRY HINDE, of Bishopsgate Street, in the City of London.
IMPROVED EXPLOSIVE COMPOUND." A communication from abroad by Rudolf
Emanuel Sjöberg, of Stockholm, Sweden.
This Invention consists of an explosive compound or substance.
--
The compound or substance is preferably made of the following :-
64
12
parts of nitroglycerine.
parts of nitrate of ammonia, soda, or urea.
0.25 part of palmitinate of cetyl.
0-25 part of carbonate of lime.
23 parts of prepared vegetable or animal charcoal.
0.50 part of bicarbonate of soda.
" AN
The constituents may and ought to vary, same depending upon the different
purposes for which the explosive is to be used.
The important points of this Invention are the following:-
(1.) Its blasting power is equal to that of nitroglycerine.
-
(2.) It does not explode by strokes or blows, but only by means of a detonating
cap.
(3.) It explodes completely.
(4.) When exploding no injurious gases are disengaged.
(5.) It possesses the property of neutralizing itself.
(6.) It remains unchangeable at a low temperature.
(7.) It possesses a greater specific weight than other explosives, hence it can be
kept during a considerable lapse of time.
(S.) It presents by far less risk in manufacturing, transporting, storing, and using
it than is the case with other known explosive substances depending on the chemical
composition of the ".
"petralithe."

This Invention consists of an explosive compound or substance which I term
petralithe.
The compound or substance is preferably made of the following:-
64
12
parts of nitro-glycerine.
parts of nitrate of ammonia, soda, or urea.
0.25 part of palmitinate of cetyl.
0-25 part of carbonate of lime.
23 parts of prepared vegetable or animal charcoal.
0-50 part of bicarbonate of soda.
The constituents may and ought to vary, same depending upon the different
purposes for which the explosive is to be used.
The important points of this Invention are the following:-
(1.) Its blasting power is equal to that of nitro-glycerine.
-
(2.) It does not explode by strokes or blows, but only by means of a detonating
cap.
(3.) It explodes completely.
(4.) When exploding no injurious gases are disengaged.
(5.) It possesses the property of neutralizing itself.
(6.) It remains unchangeable at a low temperature.
(7.) It possesses a greater specific weight than other explosives, hence it can be
kept during a considerable lapse of time.
(8.) It presents far less risk in manufacturing, transporting, storing, and using it
than is the case with other known explosive substances depending on the chemical
composition of the "petralithe."
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the said Invention of "An Improved
Explosive Compound," substantially as herein before set forth and described.
In witness whereof, I, the said Samuel Henry Hinde, have hereunto set my a
hand and seal, this Fifth day of November, in the year of our Lord One
thousand eight hundred and eighty one.
Witness,
GEORGE GILBERT.
