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?
