Currently the system is still down.  We have repaired the hoist but now 
have a problem with the system not sensing when the chamber is at 
atmosphere.  We believe that the "at atmosphere" switch is the cause for 
the hoist problem.  The switch activated to soon which enabled the user 
to raise the chamber even though it's  still under partial vacuum.  We 
are continuing to troubleshoot.
