[Stoves] Magh Utham Woodgas Burner

[acparker at xmission.com]

I have attached images (.gif) from US Patent 13674 that show a modified
Argand (center draft) lamp.  You can view/download .tif images of the
complete three page document here: 
<http://patft.uspto.gov/netahtml/PTO/srchnum.htm>

Type 13674 in the query box to get to the document images.

Early Aladdin and Rayo lamps (and many, many others) were also center
draft and there are some decent sites that describe these lamps.

I have an old Perfection kerosene heater and took a look at it.  It
varies a little in configuration of the flame spreader, but it is still
recognizable as a modified Argand burner.

You can download a copy of Damon Ogle's study on controlling draft in
Rocket Stoves here:

I have a couple of ideas for modifications, but I still need to draw
them up.  I will post them as soon as I can produce something legible.
