Donald,
Please provide the patent/document references for what you cut and pasted. What documents did they come from?
The way they were cut and pasted, it may seem to someone that they belong together, but I believe they may have come from different documents/patents and in different contexts referring to different systems.
Now, at the bottom # 6 he mentions the slots. It has been speculated that these slots were for acoustic tuning. I find that speculation pretty weak considering that Meyer clearly states,
"...the outside element comprises a longitudinal slot to provide a side projection output. "
It seems the slots were simply used to channel the output horizontally. There's no evidence that Meyer cut slots to acoustically tune the tubes.
In regards to the phenomenon that Gauss observed, the vibrations and or seemingly higher output, that is interesting. It is especially interesting that it went away after making some changes.
What was changed ?. The water, maybe the wiring/ wire lengths. The water level, the spacers? What else?
All these can have an effect upon a resonant system. Change one thing and resonance can go away. Change 5 things at once and you may never get it back unless everything was meticulously documented and measured before making any changes.
As was mentioned before by Electrojolt , seat of the pants visual measurements of gas production can be very misleading. The only way to really confirm gas production it by actual measurement. This is not difficult nor is it expensive to do and is absolutely necessary for any respectable research.
I would be very careful not to draw any solid conclusions without actual gas output measurements.
