Dependent claims

An electolytic cell for the production of hologen for use as a sanitizing agent in water, comprising in combination:

a. a plurality of generally planar electrode plates having a hologen evolving coating and assembled in interleaved fashion, the electrode plates further having two opposing substantially parallel sides, a first side being longer than a second side, and interconnected by an obliquely angled third side with respect to the two opposing substantially parallel sides and a fourth side, the plurality of electrode plates being assembled so that the first longer side of each electrode plate is alternately arranged with respect to the adjacent electrode plates on an oposing side;
b. a first bus bar and a second bus bar connectable to a source of electrical power external of the electrolytic cell connected to the plurality of generally planar electrode plates adjacent the intersection of the first longer side and the obliquely angled third side such that the first bus bar is connected to every other electrode plate and the second bus bar is connected to the remaining electrode plates;
c. a housing surrounding the plurality of electrode plates within which the plurality of electrode plates fit;
d. a plurality of electrode plate retaining means within the housing forming a plurality of grooves into which the two opposing parallel sides of the electrode plates fit to hold each electrode plate in place to maintain uniform spacing between the adjacent electrode plates;
e. an inlet end closure means with an inlet conduit to close the inlet end of the electolytic cell and to permit water to flow into the cell for electrolysis, the inlet end closure means further having a first cone-shaped orifice through which the first bus bar passes and a scond cone-shaped orifice through which the second bus bar passes;
f. an outlet end closure means with an outlet conduit to close the outlet end of the electrolytic cell and to permit water and halogen to flow out of the cell;
g. a first fixture and a second fixture connected to the housing through which pass the first bus bar and the second bus bar prior to exiting the cell;
and
h. a first elastomeric seal fitting about the first bus bar and a second elastomeric seal fitting about the second bus bar, the first eleastomeric seal and the second elastomeric seal being compressed into the first and second cone-shaped orifices, respectively, by the pressure of the inlet end closure means transmitted through the first fixture and the second fixture, respectively, to the first and second elastomeric seals to effect a liquid-tight seal at the first and second cone-shaped orifices.
