New or Improved Process and Apparatus for Purifying Liquids.
I, HEINRICH FRIEDRICH CONRAD EBELING of Gut Glinde bei Reinbek near
Hamburg, in the Empire of Germany, Doctor of Philosophy, 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 :-
The chief object of this invention is to recover from water or other liquid any
useful matters contained therein or to separate therefrom unnecessary matters, and
to produce therefrom useful products by further treatment.
I effect this object by submitting the liquid to be treated to the action of a
centrifugal machine, and at the same time to the action of magnete. The
magnetism acts not only on the solid metal but also on the metal and metallic
salts in solution. Such salts are frequently contained in liquids in large quantities
and they can be recovered with great ease and safety by this process.
The process is important not only for the recovery of useful matters but also
from a hygienic point of view, as water for example treated in the centrifugal
machine is completely freed from particles of fat and dirt, because such matters
collect against the walls of the centrifugal machine from which they can be easily
removed.
By these means the bacteria sometimes present in water are removed in great
numbers, so that water almost free from bacteria is obtained.
If water containing ammonia has to be dealt with the useful material ammonia
can be recovered by first precipitating it by chemical means as by chloride of
platinum for example, and then the recovery of the ammonia can be easily effected
by the apparatus hereinafter described. It may be observed that by removal of
the ammonia from the water the nourishment for bacteria is destroyed so that
water free from germs is obtained.
In the accompanying drawing is shown partly in section and partly in elevation
an arrangement of apparatus constructed in accordance with the invention.
In a frame a is secured a footstep 6 carrying a shaft c which runs up into a
vessel or container g which terminates at its upper end in a hollow shaft d. This
hollow shaft is supported by a bearing 61 and surrounds a central tube e which
descends to near the bottom of the vessel g, is funnel shaped at its lower end, and
serves for the introduction of the water or other liquid to be treated. The vessel g
is provided with ribs h, and consists as do also the said ribs of soft iron. The
ribs are of such a form as to be suitable for being wound with wire i.
Outside of this wire winding and on the frame a are placed a number of electro-
magnets which are excited from any suitable source of electricity.

The vessel is also provided with two outlet pipes m and o; the first of these
pipes is placed near the periphery of the vessel y whilst the second is placed near
the centre thereof. This vessel is provided with a cover or door (not shown in
the drawing) through which it can be easily cleaned.
When the vessel g is rotated the pipes m and o are carried round over the
roughs s and t respectively.
The vessel g may be rotated by any suitable means; according to the arrangement
hown in the drawing the vessel itself forms the armature of a dynamo machine.
In this case the shaft c carries a commutator v.
The action of the apparatus is as follows:-
The water w for example to be purified is introduced through the pipe e into

page_text: the vessel g near the bottom thereof, while the vessel rotates rapidly. The water
containing the heavier matters is driven by the centrifugal force towards the inner
wall of the vessel, while that containing the lighter matters remains near the
middle of the vessel, the fatty and other solid matters are driven outwards so as
to lie against the inner wall of the vessel which is strongly magnetic and attracts
the metallic salts
All the matters which are thus driven by centrifugal force or drawn by magnetism
towards the periphery are conducted into the troughs through the pipe m, or can
be removed from the vessel as occasion may require, whilst the purified water near
the middle of the vessel is conducted into the trought through the pipe o.
It is obvious that the construction of the apparatus may be varied without
departing from the essential feature of the invention, which consists in the
combination of a centrifugal machine with magnetism.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. The process for removing impurities and other matters from liquid which
consists in subjecting the liquid to the action of a centrifugal machine and at the
same time to the action of magnetism, substantially as described.
Second. For the purpose of carrying out the process forming the subject of the
first claiming clause hereof, the apparatus which consists of a centrifugal machine
the rotating vessel g of which forms the armature of a dynamo machine, whereby
the said vessel is set in rapid rotation and is rendered powerfully magnetic,
substantially as described.
