This topic will be for discussion on Stans switching techniques..  The goal is to systematically break the 661 patent down into sections. By doing so it will allow for more direct disscusion, which is the proper way to decipher mechanisms that are unclear.. "systematically"

In the pic below we have Stans schematic representation of his control circuit for gating the Scr.

There is three parts to this that need detail..

1. image 22-the Regulated dc power supply
2. image 24- the variable pulsing circuit
3  R2- variable resistor

We need to discuss the components involved and create schematics..



notice that stan is feeding the variable pulsing circuit a positive unipolar dc voltage from the same source powering the scr.. 
To me this is all about timing the circuit with the triggering

lets start with figure 22.. can anyone explain the construction of this device?

Im guessing the regulated d.c (22) may be a step down transformer..

i would say 120hz 120v - 120 hz 5v conversion

the variable pulsing circuit would some how take the 120hz 5v and be able to sync the the pulses into a 50 percent variable duty..

Question. If you were able to step down the unipolar voltage into a common circuitry bearable potential like 5-12v,  would the unipolar pulses act like a digital signal? if you had a decade counter taking in the 5-12v unipolar pulses would that not be functional and sync the switching?

22 = step down transformer or two or three voltage regulators... in series, with capacitors...


24 = gate frequency, to control how may of the 120hz pulses go to the water per second...


notice that the ground of 22 is connected to the positive of the vcc of 24


man i think that he designed his thing  to work on harmonics resonances from this 120hz the duty only control how much pulses to control the energy going in or coming out... thats why he needed a tuning inductor...


maybe when he found the pll he understood he could work on higher frequencies without much tuning inductors or other components  ...

This is the exact same circuit that Dynodon released details on, it's the same as the 8XA for the plate cell.

In this simulated circuit i am supplying 60hz 120 volts a.c.  I have the transformer as a 1:3 ratio..  Most importantly i have the rectifier connected as Stan showed in his writings.  i stopped at the scr in the circuit.. i added a output so you could see the voltage on the source side of the scr..  the trans former is doing what stan said it would.. it is charging.. there are no capacitors in this ciruit just a source, transformer, rectifier, and scr
