IMPROVEMENTS IN TREATING PETROLEUM AND ITS PRODUCTS, AND IN THE APPLICATION OF APPARATUS FOR THAT PURPOSE
Year: 1864

page_text: LETTERS PATENT to Bondy Azulay, of Rotherhithe, in the County of
Surrey, Printer, for the Invention of "IMPROVEMENTS IN TREATING
PETROLEUM AND ITS PRODUCTS, AND IN THE APPLICATION OF APPARATUS FOR
THAT PURPOSE."
Sealed the 2nd December 1864, and dated the 3rd June 1864.
PROVISIONAL SPECIFICATION left by the said Bondy Azulay at the
Office of the Commissioners of Patents, with his Petition, on the 3rd
June 1864.
I, BONDY AZULAY, of Rotherhithe, in the County of Surrey, Printer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN TREATING
PETROLEUM AND ITS PRODUCTS, AND IN THE APPLICATION OF APPARATUS FOR THAT
PURPOSE," to be as follows:-
In treating, disinfecting, and removing the bad smell from petroleum and
products thereof, it has been usual to employ chloride of lime in a dry state,
and in combination with other matters, but which, however, is very imperfect
in its action and far from obtaining the desired results.
Now according to my Invention I treat the oils with a saturated solution of
chloride of line, and as it were wash the oils in the solution. For this pur-
pose I place the oil in a suitable vat or vessel, and pour the solution over it,

page_text: the solution sinks through the oil, and I provide a means of drawing it off at
the bottom, and by a pump or other means elevate it again to the top; and so
on, keeping up a circulation of the solution in the oil, and thus abstract the
impurities from the oil and render it clear and quite free from offensive smell,
besides enhancing its lighting properties. Instead of pumping the solution up
again and again for one vat, it may pass from one vessel to another at a lower
level, and so on until the disinfecting and other properties of the solution are
too much vitiated to be of further advantage. Instead of the solution of
chloride of lime being applied at the top and drawn off at bottom, the oil
may be forced in at the bottom of a vessel containing the solution of chloride
of lime, when it will rise through the solution and may be drawn off at the
top, repeating the operation as often as may be necessary, according to the
quality of the oil operated upon. Other impurites are also separated from
the oils besides those abstracted by the solution of chloride of lime, which
other impurities sink to the bottom of the oil, which may be drawn off quite
clear and purified from offensive odours..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Bondy Azulay in the Great Seal Patent Office on
3rd December 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BONDY
AZULAY, of Rotherhithe, in the County of Surrey, Printer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of June, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Bondy Azulay, Her special licence that I, the said Bondy
Azulay, my executors, administrators, and assigns, or such others as I, the said
Bondy Azulay, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time, and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN TREATING
PETROLEUM AND ITS PRODUCTS, AND IN THE APPLICATION OF APPARATUS FOR THAT
PURPOSE," upon the condition (amongst others) that I, the said Bondy Azulay,
my executors or administrators, by an instrument in writing under my or
their, or one of their hands and seals, should particularly describe and ascertain.

page_text: the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Bondy Azulay, 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 (that is to say) :-
In treating for disinfecting and removing the impurities from petroleum
and products thereof it has been usual to employ chloride of lime in a dry
state and in combination with other matters, but which, however, is very
imperfect in its action and far from obtaining the desired results.
Now according to my Invention I treat the oils with a saturated solution of
chloride of lime, and as it were wash the oils in the solution. For this
purpose I place the oil in a suitable vat or vessel and pour the solution over
it, the solution sinks through the oil, and I provide a means of drawing it up
from the bottom, and by a pump or other means elevate it again to the top,
and so keep up a circulation of the solution in the oil, and thus abstract the
impurities from the oil, which is rendered clean and quite free from offensive
smell, besides enhancing its lighting properties. If the oil is not very bad the
same solution may be used again. If the oil is bad the solution will be found
to have acquired the taint of the oil and must not be used again. If the oil is
very bad it may be found necessary to repeat the process with a fresh solution ;
in that case I provide a second vat, the top of which would reach the oil tap
of the first vat; I then draw the treated oil from the first into the second vat
and wash it in water. After the oil has separated from the water I draw the
water off and then throw a second solution on the oil and proceed as before.
Instead of the solution of chloride of lime being applied at the top and drawn
up from the bottom of a vessel, the oil may be forced in at the bottom of a
vessel containing the solution of chloride of lime, when it will rise through
the solution and may be drawn off at the top, repeating the operation as often
as may be necessary according to the quality of the oil operated upon.
Having described the nature of my Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is,-
First, I claim the use and application of chloride of lime dissolved in water
for disinfecting petroleum, as herein-before described.
Secondly, I claim the use and application of pumps or other analogous
apparatus for the purpose of again and again throwing the same solution on

page_text: the surface of the oil, or for forcing the oil repeatedly down to the bottom of
the solution.
In witness whereof, I, the said Bondy Azulay, have hereunto set my
hand and seal, this Second day of December, in the year of our Lord
One thousand eight hundred and sixty-four.
BONDY AZULAY. (L.S.)
