Took me a while to see the 'true' function for that non-repeating delay.
Normally you do something like that:
Activator -> Delay -> Delay -> Delay -> Delay -> Delay -> Delay -> Delay -> Delay
Then you link lights to the delay maybe with an OR between, or something, to have a timeline control.
With the non-repeating you can do this:
Activator <-> Delay <-> Delay <-> Delay <-> Delay <-> Delay <-> Delay<-> Delay <-> Activator
(not the dual links)
With that you can switch on one side, and have the chain run 'forward' when switching on the other side the chain runs backward.
With this you could built two different clocks or pulse emitters to for example have 'two way' landing lights
without having to build two separate delay-chains OR'ed into the lights.
So the 'non-repeating' never emits a signal twice in a given timespan, this will break clocks and signals coming in a second time, like a clock firing into the same non-repeating delay will use it as a filter and only trigger once, on start of the clock.
