COMPLETE SPECIFICATION.
Improvements in Electrolytic Apparatus.
I, MAX HAAS, of Bahnhofstrasse, Aue, in the Kingdom of Saxony, German
Empire, Electrician, 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 present invention relates to improvements in electrolytic apparatus, more
especially to an apparatus for the manufacture of bleaching lye.
The essential feature of my invention is that the liquid does not travel as
hitherto in a winding path that is to say, first over and then under the interme-
diate electrodes, or alternately first along the one side and then along the other
side of the electrodes, but the liquid is alternately separated into two different
streams and afterwards united again so that owing to the contrary streams whirls
are formed and thus a good mixture of the circulating liquid is being attained.
My invention will be the better understood by reference to the accompanying
drawing, in which:
Fig. 1 shows a longitudinal section through an apparatus according to my
invention,
Fig. 2 is an elevational view of an end-electrode,
Figs. 3 & 4 are elevation views of the different middle-electrodes,
Fig. 5 illustrates a horizontal section through the apparatus,
Fig. 6 illustrates a horizontal section through an apparatus of modified con
struction.
It is advantageous to employ double-pole electrodes E and to arrange the end-
clectrodes El containing the direct current so that they project above the bath.
As illustrated in Figs. 1-4, the electrodes are alternately provided with one and
two vertical lines of perforations respectively.
In order to attain an equal surface of passage through all the electrodes it is
advantageous to group the perforations so, that the number of perforations
arranged on both sides of an electrode is equal to the number of perforations
arranged in one vertical line upon the intermediate plates. If for instance the
number of the perforations in the electrodes, as represented in Figs. 3 & 4, is
equal to 2n, the intermediate plates are provided with n openings at each side..
Fig. 6 illustrates a modified form of construction by means of which the mixture
of the circulating liquid is rendered more effective and the characteristic feature of
this arrangement is that the perforations a a¹ are not arranged parallel to the
ongitudinal axis of the apparatus,, but they are arranged slanting as represented
n Fig. 6.
Having now particularly described and ascertained the nature of my said
nvention, and in what manner the same is to be performed, I declare that what
claim is;
1. In an electrolytic apparatus for the manufacture of bleaching lye, the com-
ination with double-nale elantrades.

tially as described.
2. In an electrolytic apparatus for the manufacture of bleaching lye, the com-
bination with double-pole electrodes of perforations alternately arranged.in slant-
ing directions in the middle and at the sides of the intermediate electrodes, for the
purpose and substantially as described.
