PROVISIONAL SPECIFICATION.
Improvements in Means or Apparatus for Cooling and Purifying
Liquids Discharged from Works or the like.
I JOHN HANSON of Wakefield in the County of York, Sanitary Engineer do
hereby declare the nature of my invention to be as follows:-
When hot liquids containing impurities are discharged from works or factories or
the like into streams, especially such streams as convey sewage, there is consider-
able nuisance created owing to the hot liquids stirring up, and mixing with, the
sewage, or the like, and bad odours arising therefrom.
According to my invention I cause the hot liquids to be so discharged from the
works, or the like and conducted therefrom, that, before they are allowed to mingle
with the stream, or to arrive at other place into which they are eventually received,
they become cooled and deposit such of their contents, or impurities, as are capable
of depositing whilst the liquids are conducted from the works or the like to the.
place of final discharge.
According to my invention the discharge of hot liquids from the works, or the
like, is made into a conduit which is preferably open at top, and takes the form of a
long trough, which may be in one length, or in several lengths, extending first in one
direction, and then in the other, or running to and fro in any direction.
I may
make it horizontal, or somewhat inclined towards its outlet end. In the said trough
I place partitions, so arranged as to give a zig-zag, or to and fro movement of the
liquid as it passes through the trough. These partitions may be arranged so that
they project alternately from opposite sides of the trough and leave passages
between their ends alternately at opposite sides of the trough. The discharge from
the works, or the like, is preferably made so that the hot liquors issue into the
trough in a comparatively thin, and extended, stream. During the passage of
the liquid through the apparatus it becomes so cooled that it does not cause the
harmful emission of offensive odours hitherto existing and moreover objectionable
matters, or matters which it may be desirable to recover, are deposited in the-
trough and can be removed from time to time, and any suitable outlets may be
provided for the purpose, and the matter so precipitated and removed can be treated
as may be necessary to recover any valuable matter therein.

COMPLETE SPECIFICATION.
Improvements in Means or Apparatus for Cooling and Purifying
Liquids Discharged from Works or the like.
I JOHN HANSON of Wakefield in the County of York Sanitary Engineer 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:
When hot liquids containing impurities are discharged from works or factories or
the like into streams, especially such streams as convey sewage, there is considerable
nuisance created owing to the hot liquids stirring up, and mixing with, the sewage
or the like, and bad odours arising therefrom.
According to my invention I cause the hot liquids to be so discharged from the
works, or the like, and conducted therefrom, that, before they are allowed to mingle

page_text: with the stream, or to arrive at other place into which they are eventually received,
they become cooled and deposit such of their contents, or impurities as are capable
of depositing whilst the liquids are conducted from the works, or the like, to the
place of final discharge. The discharge of hot liquids from the works, or the like,
is made into a conduit which is preferably open at top, and takes the form of a
long trough, which may be in one length, or in several lengths, extending first in
one direction,, and then in the other, or running to and fro in any direction, I may
make it horizontal, or somewhat inclined towards its outlet end.
Figure 1 of the accompanying drawing represents in plan and Figure 2 in
transverse section on the line 1. 2. Figure 1 an apparatus suitable for carrying my
invention into effect I have here shewn it in the form of a trough divided by the
longitudinal partition a into two lengths b and c communicating with each other
at d. There may of course be only one length or two or more lengths of trough
as desired. In the said trough I provide partitions f so arranged as to give a zig
zag, or to and fro, movement of the liquid as it passes through the trough as
indicated by the arrows. These partitions may be arranged most conveniently as
shewn so that they project alternately from opposite sides of the lengths b and c of the
trough and leave passages between their ends alternately at opposite sides of the
trough. The discharge from the works, or the like, is preferably made so that
the hot liquors issue into the trough in a comparatively thin, and extended, stream.
The inlet is indicated at g. During the passage of the liquid through the apparatus
it becomes so cooled that it does not cause the harmful emission of offensive odours
hitherto existing and moreover objectionable matters, or matters, which it may be
desirable to recover, are deposited in the trough and can be removed from time to
time, and any suitable closable outlets may be provided for the purpose as indicated
for example at and the matter so precipitated and removed can be treated as may
be necessary to recover any valuable matter therein. indicates the outlet for the
liquid from the trough.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Means or apparatus for cooling and purifying liquids discharged from works or
the like the said means or apparatus consisting of a conduit provided with partitions
or the like for causing the liquids to pass in a zig-zag or to and fro manner there-
through before being discharged substantially as and for the purposes herein-
before described.
