Encoder Division

Dear Mr. Dering:

\J
	Enclosed are  our  two Model  73 encoder  assemblies and  the
mounts for  them.  As I mentioned  during our phone conversation, the
hubs of  the disks are  too large  to allow  the housing  unit to  be
slipped into place.   In addition, the cable routing  is too close to
the rotor.  It will surely touch when in operation.  

	The box  labelled SCRATCH was the original box the disks were
shipped in.   I  hope those  words  are irrelevant.   In  addition, I
notice a small chip near the edge of one of the disks, I hope this is
also O.K. 

	You may  adjust the  shims  on the  rotor without  the  gear.
Unfortunately, the  one with the  gear in place  was that way  when I
talked with  you.  Should you need to remove  the gear, press it off,
and we will replace it when you return the complete assembly.  I might
add that we have  changed our design so that in  the future we will
be able to use one of your housed encoders. \.
