Who built the gated pulse gen like in the patent or like Tony and worked?I tried bouth crkts on breadboard and pcb and none of them worked....

Did you hook it up to a powersupply? 

Just kidding......

Do you see a squarewave on yr scope, without having a load to the circuit?

I see a square wave but not the gated signal from the 9xb,and when i increase duty it loses signal

this is the output on pin 8 of the 74122

The gate is only a mean for controlling gas output, in later design actually it is probably substituted by the injectors signal... think about it...

What about the stepcharging?
