Roy and Jeff:
Thanks for the US Patent Office information. I still cannot get the past the
main web page to search the patent numbers and that is why I could not find
out what I had. The design of my "What's It" is a horn to gather the IR
radiation and concentrate the IR onto the thermocouples (thermopile). I am
assuming you would use the device hooked up to a galvanometer to get
readings. So it must be a Bolometer for measuring heat output; but, what
heat output was it meant to measure? Perhaps it was to show how a flame
projects radiated heat or maybe for an incandescent light bulb. That was the
final part of the question, how is the device used for a classroom demo?
Roy, you found the device listed as an IR emitter? I could see it as a
receiver but would not want to put current through the fragile little ribbons
of metal on the thermocouples to make it an emitter. I do hope CENCO used
the correct patent number or this will be a wild goose chase.
One little note, to stop spam I have a firewall that lets in only those email
addresses I want to hear from and if you tried to get me from the link on the
"What's This?" page it may have bounced back to you. I have lifted the
firewall for a few days since clicking on my name goes to my
<SFPhysics@aol.com> address and people may be trying to reach me with the
link. The firewall will go back up at the end of a week so it is best to
contact me through the Pinhole List (the one you are reading now).
Thanks again to everyone,
Al Sefl
