[Gasification] Dasifier Metal melter

[Thomas Reed]

Dear Peter:

You are right on that Das is one of you.  He is an expert bell founder 
and has been to India to educate the Gurus there. 

I hope he'll take time to explain the Dasifier to you (and me) in an 
archival manner and we'll put it on our website.  (I couldn't find the 
picture on my site.  Is it there?)  He has also asked me to make some 
minor changes in the diagram that I drew. 

Onward,

TOM REED
