I knew I had seen this disc before at least once!

I was at a trade show, where we were showing a ACR-25 and they had carousel problems and it was traced to a crack in that disc. 

It was solid, but cracked and the IR reader was alsso reading the crack in error!

The design engineers had an impromtue contest to see who could modify the reader circuits with the least components to ignore the crack.

I believe it was Gerry Engbertson who won the drinks with a single cap in the right place that changed the reader into requiring the larger real pulses.

This was great to see great engineers, create a solution to a real problem.

Too late, Ted, Ann is retired from Lloyd's of London in New York which is located in the MOMA building, not a bad idea, though.

Hi, George, 


If you scan it at a really high resolution, you can have a very large print made and have that framed.  Less risk to the encoder disc, more of it to enjoy.  Maybe we can get MOMA in Manhattan to hang it somewhere.


The MWA Nova telecine equipment I sell uses similar encoders on various moving parts.


Cool item, and thanks for posting it.

CONGRATULATIONS HAROLD!!  YOUR CORRECT ANSWER WAS THE FIRST ONE RECEIVED HERE.
 
YOU HAVE WON A FREE HOT DOG AT THE "TEXAS WEINER" HERE IN PORT JERVIS, NY, (IF THEY EVER SHOVEL IT OUT). YOU MUST BE HERE TO CLAIM YOUR PRIZE BY 4:00PM EST TODAY. (BY THE WAY, EVEN THE TRAINS AREN'T RUNNING).
 
There were many correct answers, but Harold's was the earliest.
 
It is the carrousel encoder disc from the ACR-25.  It is about the only "Relec" saved from the dumpster of the 6 ACR's at CBS. It is such a work or art, I couldn't let it go, it was a spare. It is still in it's original wooden box. There were about 3 or 4 of them replaced over the years.  I just scanned it and it came out OK.  I would like to frame it, but can't find a reliable framer around here that I would trust to do the job.

Looks like the optical encoder wheel from an ACR-25
