I'm looking at the Godes/Brillouin patent application:
http://www.google.com/patents/US20110122984?hl=en

In figure 3C, the circuit diagram of the drive circuitry, there are
effectively three "outputs" at right: the two connection points labeled
J1-1 and J1-2, and the bulb-shaped object that is dual-labeled "Cathode"
and "F04" at right center. Then in paragraph 0045 of the text, we read:
"The center tap on the secondary of transformer T8 attached to the cathode
[...] of the loading current source."

But in Figure 9, we see three connections from the controller to the beaker
on the left (the fourth line to the left beaker is a sensor). Two of the
controller connections run to the object labeled "Cathode" in the beaker,
one to the "Anode". It's tempting to assume the paired connections to the
"Cathode" correspond to J1-1 and J1-2 in figure 3C, so the other connection
to "Anode" in Figure 9 must be the bulb shaped object which is
unfortunately labeled "Cathode" in 3C.

Thinking about this, I think that Figure 9 is correct. Figure 3C and
paragraph 0045 are in error; the bulb-shaped object in 3C should be labeled
"Anode". Here's why:

1) Looking back at the circuit diagram 3C, it makes sense for the "reactant
loading pulse" to run to the anode. In other words, instead of an ordinary
continuous DC electrolytic cell, Godes is pulsing the current to the anode.
By controlling pulse width and frequency, he can control the rate of the
electrolysis reaction.

2) J1-1 and J1-2, on the other hand, run to the ends of the taps on the
transformer. I believe the drive circuitry at lower left, combined with the
caps C2 and C5, form a differentiator: the circuit generates short,
powerful spikes across the primary of T8 as the big power FETs at lower
left switch on and off. These spikes (the "Q pulses") couple across the
isolation transformer T8 and  look like AC to the core since the are
referenced to the sort of "virtual ground" formed by the center tap of T8.

Thoughts?
