What u mean by the pulses can't overlap? explain more pleaseThey cannot overlap.
What do you mean how the series cap creates this train of signals? what kind of signals? are they spikes? train of spikes?The series capacitors are an easy way to create this train of signals.
So it's an RC passive timer? not an RC network delay?It is not called a delay, instead it is a simple timer.
But there is an RC network, what does that RC network do? its a waveshaping RC network?1) In the upper schematic there is an RC delay on the left side that you did not see, and on the right side there are two fast (no delay) latching circuits that you circled and wrongly labeled "RC delay".
