1986 automatic chlorine feeder $39.00

Has anyone ever seen one of these. It's hard to tell from the 1986 ad how it may have worked:

I wonder how well it worked.

I'm pretty sure that's just the venturi injector from a unichlor/porpoise brine tank chlorine generator.

They work but are subject to feed variations due to inconsistent flow in the circulation system like when a filter starts to get dirty.

It's the same principle as a Mazzei injector.
