Printed Circuit Board Flipper/Inverter

      A device which flips or inverts printed circuit boards on a
horizontal conveyor is described in Figure 1.

      Operation:
           1 - Board falls from A to B
           2 - Board flipped from B to C
           3 - Inverted board conveyed from C
           4 - Repeat

      Application: Any process requiring panel inversion.  Especially
useful as mid-etch flipper when etching fine line product or other
product which requires close control of top/bottom circuit feature
size.

      Attributes:
           1 - Simple - Few components
           2 - Reliable - Components same as, or compatible
               with, conveyor
