					             Team 7 - Project 99.07




Team Members:
   J. M. Tate, J. Acheson, P. Sullivan, and A. Abumohor
Advisor: Dr. J. Glancey         Sponsor: Dr. Limin Kung
Mission: The purpose of our team is to design
 and build a means to quickly and reproducibly
 load a test silo without requiring extensive
 manpower.

Approach: We will use the Total Quality
 Design Process, through the SpreadSheet
 Design Process on Microsoft Excel.

Pros and Cons based upon
 metrics and target values
   Feeding Mechanism: Screw

   Force Control: Mechanical

Sink Depth: Feed Stopping Switch
We start by installing one stopper
into the minisilo.



          8.25in
  This minisilo is then locked into
        the sliding carriage.

The cut off switch satisfies the
proper sink distance constraint.

 Force: Pneumatic Piston

   Force Control: Valve

Feeding Mechanism: Linear
   Reciprocating Feeder
Again, we start by installing one
stopper into the minisilo.
