PROVISIONAL SPECIFICATION.
Improved Insulating Material for Electrical Purposes, and Method
of Producing same.
I, ADOLF GENTZSCH, of II Ottakringerstrasse, in the City of Vienna, XVII,
in the Empire of Austria, Mineralogist, do hereby declare the nature of this
invention to be as follows:-
:-
The production from mineral substances of an insulating material for electrical
purposes has long been a subject of experiment and investigation, but, up to the
present, only very insignificant results have been obtained; consequently, it has
always been necessary to resort to vegetable substances. for producing a good and
durable material possessing high insulating properties.
It has been recognized that a serviceable insulating material could be obtained, if
it were possible to oxidize mineral oils. But, nature herself provides such oxidized
mineral oils for instance, ozokerite, asphalt, amber, idrialite, hatchetine etc.-
which, however, are brittle and hygroscopic, and possess very little insulating
properties.
According to my invention, the above substances form the basis of this improved
insulating material; those substances however being removed which prejudice or
deteriorate the insulating properties. It is therefore possible to obtain an insulating
material which is not only not inferior to that obtained from oxidized, but, in fact,
possesses far superior qualities.
The fossil resins, particularly ozokerite, asphalt and amber, are subjected,
according to this invention, to a process of distillation, a boiler, or preferably
a still being employed for that purpose. Water, light and heavy oils and gases
escape during the heating of each or a mixture of the said substances.
When it is observed that gases, vapor, or oils cease to escape, the heating is
discontinued and the mass allowed to cool. In that condition the mass is of a
butter-like consistency and pliable or supple, and it may either be employed alone
or incorporated with other substances in appropriate proportions for insulating
cables, and as material for terminal and intermediate connections.

Improved Insulating Material for Electrical Purposes, and Method
of Producing same.
I, ADOLF GENTZSCH, of II Ottakringer Strasse in the City of Vienna XVII,
in the Empire of Austria, Mineralogist, do hereby declare the nature of my said
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The production from mineral substances of an insulating material for electrical
purposes, has long been a subject of experiment and investigation, but, up to the
present, only very insignificant results have been obtained; it has therefore always
been necessary, to resort to vegetable substances for producing a good and durable
material possessing high insulating properties.

page_text: It is known that a good insulating material could be obtained, if it were possible
to oxidize mineral oils. Nature herself, however, provides such oxidized mineral
oils for instance, ozokerite, asphalt, amber, idrialite, batchetine etc.-but these
are brittle and hygroscopic, and possess very little insulating properties.
According to my invention, the above substances form the basis of this improved
insulating material; those substances, however which prejudice or deteriorate the
insulating properties are removed. It is therefore possible to obtain an insulating
material which can be used alone i.e. without the incorporation of additional
substances and which is in no way inferior to that obtained from oxidized oil of
vegetable origin, but in fact, possesses far superior qualities.
According to this invention the fossil resins, particularly ozokerite, asphalt and
amber, are subjected to a process of distillation, preferably in a closed still to a
temperature of about 400° centigrade. Water, light and heavy oils and gases
escape during the heating of each or a mixture of said substances.
After the mass has been heated until gases, vapor, or oils cease to escape, it is
allowed to cool. In that condition the mass is of a butter-like and pliable consis-
tency and may either be employed alone or incorporated with other substances for
insulating cables such as resins, fats, or oils, the proportions of these being from
say 30% to 70%, and as a material for terminal and intermediate connections.
As an example of the employment of the substances herein named for producing
the insulating material, the following proportions are found suitable:

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
1. Process for producing an improved material extracted from fossil resins for
electrical purposes, in which the resins employed (ozokerite, amber and asphalt)
are heated in a still to and retained at a temperature of about 400° centigrade until
gases or oils cease to escape, substantially as described.
2. As a new article of manufacture an improved material extracted from fossil
resins for electrical purposes substantially as described.
