page_text: I, ADOLPH SOMA ÖSTREICHER, of Sycamore Cottage, Wickham Market, in the
County of Suffolk, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
The invention relates to surface condensers as used in connection with steam
engines, refrigerators and the like, where the cooling takes place by the evapora-
tion of water. It consists in the employment of a dephlegmator for separating
the oil from the steam before it enters the condenser proper, and the employment
of a constant and an intermittent supply of circulating water.
The dephlegmator is cooled, either by the surrounding air or by water, and its
action is augmented by the introduction of fine materials (powder of graphite
or other suitable material) or liquids (water or oil).
In the drawing represents A the dephlegmator, which however can form part
of the eduction pipe a, b is the receptacle for fine materials, to the water-lank,
the injection nozzle, the drain-pipe for the phlegm (grease and water).
B the condenser proper: ƒ the constant supply pipe; & the intermittent tank
with its discharge pipe g; C the mixer receiving air by the pipe and the phelgm
by pipe d.

I, ADOLPH SOMA ÖSTREICHER, Mechanical Engineer, of Middle Street, Wick-
ham Market, County of Suffolk, 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:-
This invention relates to surface condensers as used in connection with steam
engines, refrigerators and the like, where the cooling takes place by evaporation
of water.
To ensure a great efficiency in transmission of heat through the metallic sur-
faces of condenser, it is necessary that the grease, contained in the steam to
be condensed, should be extracted before entering the condenser proper, otherwise
it adheres to the walls and acts as an insulator: further as experience has shown,
the efficiency of evaporative condensers increases "with the thinness of the
water film.
The object of this invention is to carry out the before mentioned desiderata

page_text: of an economical condenser, primarely by the separation of grease, and by
adopting the smallest possible supply of circulating water.
Fig. 1, on drawing filed with my Provisional Specification, shows the outlines
of the new condenser in which the letters indicate: -a steam or eduction pipe,
A the dephlegmator with the receptacle for fine materials, to the water tank,
2 the fresh water supply, q the injection nozzle, o the overflow from water tank 1,
and the drain pipe. B the condenser proper, the air pipe, & the drain pipe
for condensed water. C the mixer receiving the drains from A and air from B,
leading from thence by the mixture pipe c'air and plegm to the air pump D.
The circulating pump E receives the water from the collecting tank and
delivering it by pipe to the constant supply,pipef and the intermittent tank G,
from whence it passes over the condenser 13 by pipe g.
The feed pump F draining the condensed water by pipe and delivering it
by pipe m to the boiler.
The separation of grease takes place in the dephlegmator A, which however
can form part of eduction pipe a. It is cooled either by water in tank w, which
is needed to make up the loss due to evaporation or by the surrounding air." The
phlegm (grease and water) is carried off by drain pipe d, whilst the steam entei's
the condenser B. The separation of grease can be aided by introducing absorbing
materials as powdered graphite, powdered lignito, hydrate of aluminia, parafin
or any other fine matter; 5 shows the receptacle for these, with a fine outlet,
by which they enter the dephlegmator. To wash off accumlations, a. jet of
water is introduced into the dephlegmator by the nozzle q.
The thinnest water film is secured by a double supply: a constant one through
pipe f, and an intermittent (to ensure that the sides of the condenser are always
kept moist, and accumlations of dirt washed off) from the intermittent or
flushing, tank G, through pipe g.
Having now particularly described and ascertained the nature of my said
invention and in' what manner the same is to be performed, I declare that what
I claim
:
1
1) The separation of grease before entering the surface condenser by means
of a dephlegmator.
2.) The application of absorbing substances in connection with evaporative
condensers to augment the action of the dephlegmator.
3.) The employment of an intermittent supply for flushing purposes in con-
nection with evaporative condensers.
4.) The employment of an intermittent tank in connection with evaporative
condensers.
