AN IMPROVED MODE OF TREATING SEAWEED
Year: 1871

page_text: LETTERS PATENT to Benedict John Angell, of Lubenham, Market
Harborough, Leicestershire, Gentleman, for the Invention of "AN
IMPROVED MODE OF TREATING SEAWEED."
Sealed the 23rd February 1872, and dated the 26th October 1871.
PROVISIONAL SPECIFICATION left by the said Benedict John Angell.
at the Office of the Commissioners of Patents, with his Petition,
on the 26th October 1871.
I, BENEDICT JOHN ANGELL, of Lubenham, Market Harborough,
Leicestershire, Gentleman, do hereby declare the nature of the said
Invention for "AN IMPROVED MODE OF TREATING SEAWEED," to be as
follows:-
The object of my Invention is to obtain from seaweed a material
preferably in the form of a jelly, which material shall contain ozone.
This jelly or material will be found useful for many purposes where
ozone is beneficial; for instance, when placed in suitable proportion in
water or other liquid it has the effect of ozonizing the liquid. Ozone
baths may thus be prepared without difficulty.

page_text: To obtain this ozone jelly or material I treat the seaweed in any
manner which will extract the essence therefrom, say by boiling or
distilling, and this essence constitutes the said jelly or material.
The Invention may be advantageously carried into effect as follows:-
The seaweed having been cleaned is cut up or reduced, and placed in a
close vessel in which it is heated to a temperature of about 300°
Fahrenheit, more or less, by steam and hot water, which are caused
to circulate in a coil or worm in the said vessel. The effect of the heat
is to cause the seaweed to give off a gas or vapour which is conducted
from the top of the said vessel by means of a pipe to any ordinary
condensing apparatus. The gas or vapour is thus condensed in this
apparatus into a liquid state, and when the liquid cools it becomes a
jelly. This jelly is the essence of the seaweed and contains ozone.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Benedict John Angell in the Great Seal Patent
Office on the 24th April 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENEDICT
JOHN ANGELL, of Lubenham, Market Harborough, Leicestershire,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of October, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty.
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Benedict John Angell, Her special licence
that I, the said Benedict John Angell, my executors, administrators,
and assigns, or such others as I, the said Benedict John Angell, 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 "AN
IMPROVED MODE OP TREATING SEAWEED," upon the condition (amongst others)
that I, the said Benedict John Angell, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands

page_text: and seals, should particularly describe and ascertain 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
3 Letters Patent.
NOW KNOW YE, that I, the said Benedict John Angell, 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 thereof, reference being had to the
accompanying Drawing, that is to say :-
The object of my Invention is to obtain from seaweed a material
preferably in the form of a jelly, which material will ozonize liquids..
This jelly or material will be found useful for many purposes where
ozone is beneficial; for instance, when placed in suitable proportion in
water or other liquid it has the effect of ozonizing the liquid. Ozone
baths may thus be prepared without difficulty.
To obtain this ozone jelly or material I treat the seaweed in any
manner which will extract the essence therefrom, say by boiling or
distilling, and this essence constitutes the said jelly or material.
The Invention may be advantageously carried into effect as follows:-
The seaweed having been cleaned is cut up or reduced and placed in a
close vessel in which it is heated to a temperature of about 300° to 400°
Fahrenheit, more or less, by steam and hot water, which are caused to
circulate in a coil or worm in the said vessel. The effect of the heat is
to cause the seaweed to give off a gas or vapor which is conducted
from the top of the said vessel by means of a pipe to any ordinary
condensing apparatus. The gas or vapor is thus condensed in this
apparatus into a liquid state, and when the liquid cools it forms a
jelly. This jelly is the essence of the seaweed.
The annexed Drawing represents in clevation (partly in section) an
apparatus suitable for carrying my Invention into effect.
A is a furnace containing a coil of high-pressure steam piping, which
is in communication at top and bottom by means of connections a and b
respectively with the top and bottom of a coil in a still B. The seaweed
to be treated is placed in this still B within the said coil, and becoming
heated by the hot water or hot water and steam circulating through the

page_text: coil, gives off a gas or vapor. This gas or vapor is conducted by a pipe c
to a condenser C, in which it becomes condensed, passing off into a
suitable receiver at D. The seaweed is supplied to the still B by means
of a slide at d, where a hopper may be attached. The charge is with-
drawn from the still after the juices have been evaporated, by means of
a cover or door at e.
The still B and condenser C are fixed on a cast-iron bed plate E.
I prefer to employ a range of stills and condensers, all the stills being
heated from the same furnace, the circulating hot water passing from
one still to another and finally returning to the furnace.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim treating
seaweed substantially as herein-before described.
In witness whereof, I, the said Benedict John Angell, have hereunto
set my hand and seal, this Twentieth day of April, One thousand.
eight hundred and seventy-two.
B. J. ANGELL. (L.S.)
