Well, nice of you to worry about me copying, copyrighted work and suffering
a penality, but let me worry about that... and MOST technical docs have fallen to public domain QUICKLY--especially this stuff which was cutting edge technology--when my grandfather was a boy... There is also "fair use", you may want to read up on it... since the drawing I pasted here is less than a page (much less) it OBIVIOUSLY would fall under this--and I would be covered yet again... Most importantly is the necessity to get facts and info into the hands needing it, in a form which they can understand--in a manner which does not chase them off.. something I DON'T see happening here. Warmest regards, John "J. Mc Laughlin" wrote in message ... 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. Mac N8TT -- J. Mc Laughlin; Michigan U.S.A. Home: "John Smith" wrote in message ... ... 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 "Ian White GM3SEK" wrote in message ... John Smith wrote: Here is a url to a page I put up--shows both a 1:1 and a 4:1 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.) -- 73 from Ian GM3SEK 'In Practice' columnist for RadCom (RSGB) http://www.ifwtech.co.uk/g3sek |
