[QuadList] Puffer

[george keller]

WOW! I am impressed, nobody knows that one, well almost nobody.  You are right it is on the ACR 25.  It gives a small blast of air right at the exit point of the "Canoe".  It prevents a crease in the middle of the tape which causes the oxide to "Spit" or come streaming right off the tape because of this crease during rewind.  You must have been wide awake during Cecil Browns class when he demonstrated this phenomenon on a piece of tape.  It is actually hard to do by hand and I think it didn't show up on the schematic or it was buried somewhere.

Great answer and memory.

Thanks,

George Keller

That brings back some old thoughts.
I will start with something to do with the Ampex ACR-25 threading. I think the tape needed a gentle push at some point but I do not recall the details.

FYI,,

 

Years ago a couple of us went to a VPR 2 (?) Maint. course at ABC.  We had been working on the ACR's for a few years and had great respect for it.  One of the ABC guys took us around his plant and showed us the TCR and let us see how it worked by opening the back so we could see how it threaded tape.  When it started it's cycle, we both burst out laughing, it just seemed funny.  All I could think of was an automatic Chinese laundry ironing machine, with those arms coming out from somewhere and pulling the tape out of it's cart. This was the first time we had seen a TCR. I wonder what the geniuses at Ampex thought about that machine.  They had the right  idea.

Here is a trivia question, What is a "Puffer"??
