PROVISIONAL SPECIFICATION.
.
Improvements in the Method of Purifying and Decolorizing
Saccharine, Amylaceous, and other Fluid Bolies. .
I, DAVID BLYTH, of 46 Oxford Road, Kilburn, in the County of Middlesex,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of purifying and decolorizing
certain fluid bodies, more particularly sugar cane, sorghum, or beet juice and other
saccharine fluids, glucose and other amylaceous fluids, sewage water and other
water.
/
In carrying my invention into practice, the said fluids are filtered through a, bed
of magnetic oxide of iron, the said bed being of the necessary thickness for the
relative impurity of the fluid to be treated.
No fluid is allowed to pass through the floor of the filter bed, except at certain
points where regulators are placed to control the flow of the filtered fluid. These
regulators are provided with covers made of compressed coke, or other suitable
material which will act as a conductor of electricity.
To these covers, copper, wires are attached, communicating with an electrical
battery, dynamo, or other suitable source of electric current, outside the filter bed,
by means of which electricity, is conveyed as frequently as required through the
entire bed of magnetic oxide, thus increasing the quantity of ozone generated by
the said oxide and more thoroughly, purifying and decolorizing the fluids passing
through.
Oxygen gas.may also be forced into the filter, bed of magnetic oxide, to assist
its action.

Improvements in the Method of Purifying, and Decolorizing
Saccharine, Amylaceous, and other: Fluid Bodies.
I, DAVID BLYTH, of 46 Oxford Road, Kilburn, in the County of Middlesex,
Gentleman, 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 an improved method of purifying and decolorizing certain
fluid bodies, more particularly sugar, cane, sorghum, or beet juice and other
saccharine' fluids, glucose and other amylaceous, fluids, sewage water and other
water.
In carrying my invention into practice the said fluids are filtered through a bed
of magnetic oxide of iron, the said bed being of the necessary thickness for the
relative impurity of the fluid to be treated.

page_text: No fluid is allowed to pass through the floor of the filter bed, except at certain
points where regulators are placed to control the flow of the filtered fluid.
These regulators are provided with covers made of compressed coke, or other
suitable material which will act as a conductor of electricity, or the said covers
may be of ordinary construction and blocks of such material may be attached to
them.
To these covers, or blocks insulated copper wires are attached, communicating
with an electrical battery, dynamo, or other suitable source of electric current,
outside the filter bed, by means of which electricity is conveyed as frequently as
required through the entire bed of magnetic oxide, thus increasing the quantity of
ozone generated by the said oxide and more thoroughly purifying and decolorizing
the fluids passing through.
Oxygen gas may also be forced into the filter bed of magnetic oxide by any
suitable means to increase the amount of ozone generated.
In the accompanying two sheets of drawings, which form part of this Specification,
and in which similar letters of reference denote similar parts throughout;
Fig. 1 is a sectional elevation, and
Fig. 2 is a sectional plan, through A A in Fig. 1, of a regulator for a filter bed,
which may be employed in connection with my invention.
'
Fig. 3, is a plan to a reduced scale, of part of a filter bed, shewing a method of
arranging the electrical connections.
Referring to Figs. 1 and 2, B is a hollow cylindrical chamber, open at the top,
and provided with a cover C, made of compressed coke, or other suitable material,
which is at the same time a conductor of electricity. Orifices D are formed in the
bottom of the chamber B, opening into the vertical pipe E, which communicates
with a main pipe F. The outer surface of the chamber B, is preferably formed
with vertical flutes, or corrugations H, as shewn most clearly in Fig. 2, in order to
leave clear passages between the said chamber and the cover C.
The fluid from the filter bed passes up between the said cover and chamber, then
through suitable material J packed within the chamber, in such manner as to
regulate the flow of the fluid to the desired rate, and finally makes its exit through
the orifices D into the main F.
K is the insulated conducting wire attached to the cover C by any suitable device,
such as L.
As before mentioned, the cover C may be of ordinary construction, and a block,
or blocks of suitable conducting material be affixed to them, to which said block,
. or blocks, the wire K would be attached.
In Fig. 3, which represents two rows of regulators, on a filter bed, M is the main
lead from one pole, and N the main lead from the other pole of the dynamo or
battery employed to generate the current, one row of regulator covers C is
connected by a wire K to the lead M, and the other row C' by a wire K₁ to the
lead N, so that the current will pass from the covers C to the covers C¹, through
the layer of magnetic material on the filter bed, in which the said covers are immersed.
I am aware that the particular pattern of regulator, herein shewn and described
is not new, and I therefore make no claim thereto, nor do I necessarily confine
myself to the specific mode of arranging the electrical connections as set forth.
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. The herein described process for purifying and decolorizing, saccharine,
amylaceous and other fluid bodies, consisting in the filtration of the fluid through
magnetic oxide and passing an electric current or currents through the said bed,
substantially as herein set forth.
2. The herein described process for purifying and decolorizing saccharine,
amylaceous and other fluid bodies, consisting in the filtration of the fluid through

page_text: magnetic oxide and passing an electric current or currents and oxygen gas through
the said bed, substantially as herein set forth.
3. A filtering apparatus for purifying and decolorizing saccharine, amylaceous
and other fluid bodies, consisting of a bed of magnetic oxide, provided with
regulating exits furnished with means for transmission of electric currents through
the said bed, substantially as herein set forth.
4. A filtering apparatus for purifying and deodorising saccharine, amylaceous and
other fluid bodies, consisting of a bed of magnetic oxide, provided with regulating
exits furnished with means for transmission of electric currents through the said
bed and means for forcing oxygen gas through the said bed, substantially as herein
set forth.
