The six PDF files attached to the original of this message were not 
placed in the T10 Reflector archives in a useable format. Apparently, 
the latest and so-called greatest reflector tools cannot detect PDF 
attachments. Who knew!

Therefore, the ladder diagrams described below are being uploaded as:

All the best,
