Dear "John Smith"
The probability that you copied works that were not covered by copyright
is minuscule. For such a work not to be covered by copyright it would have
had to be declared in the public domain by the author or publisher.

Here is a link to the Copyright Office that provides some authoritative
information about low long copyright protection lasts:
http://www.copyright.gov/circs/circ1.html#hlc

Having expressed disdain for lawyers, it is unlikely that you are a
lawyer, whatever and whoever you are. The Patent Office lists three patent
attorneys with the name of John Smith. I doubt that you are one of them.

When you copy works that are almost surely copyrighted and provide no
attribution, you encourage persons with an interest in the works to track
you down. Not wise.

... as a matter of fact, they are scanned from "copyright expired"
material... I took the time to bring everyone up to speed on copyright
here... and even to know the difference between expired and not... for

some
strange reason some have difficulty dealing with this...

He is correct about it being a voltage balun, which I believe is what you
first asked about, at least that is what the balun you referenced looked
like to me--I make mistakes and could have been mistaken... however, there
is also a post from me in this thead on the current balun you can use...
when you read my post on the quick-start on the differences for
voltage/current baluns you can decide for yourself--on what you need...
baluns are a very simple thing, don't know why so much mystery wants to

end
up wrapped about 'em...

Warmest regards,
John

balun--winding diagrams are below each, respectively...

Don't bother to look - they are both voltage baluns.

(And the drawings have been scanned from someone else's copyright
material.)
