djk Posted December 16, 2005 Share Posted December 16, 2005 If you need a TIFF viewer, get it here: http://www.alternatiff.com/ Never link directly to 'IMAGES' at the USPTO, the links expire in a very short time. Link to the main page, and then the user clicks on 'IMAGES'. http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.html&r=1&f=G&l=50&s1=%2220050276431%22.PGNR.&OS=DN/20050276431&RS=DN/20050276431 Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted December 16, 2005 Share Posted December 16, 2005 Congrats Dana, I have admired your avatar for some time now. That is VERY COOL that you went the extra mile to patent your design. We are in some awesome company here on the Forum. Keep us up to date on patent news (like how long does it take for the 'pending' to go away?) and production of more working models.

D-MAN Posted December 16, 2005 Author Share Posted December 16, 2005 Armando, I ALSO did something like it back in 1973! Quote Link to comment Share on other sites More sharing options...
ajsons Posted December 16, 2005 Share Posted December 16, 2005 Dana, Who did the drawing for the patent? Quote Link to comment Share on other sites More sharing options...
D-MAN Posted December 16, 2005 Author Share Posted December 16, 2005 Thanks, I did the whole thing including the drawings. Armando, you NEED to post a thread about your Classics! We want to see more about them! DM Quote Link to comment Share on other sites More sharing options...
sunnysal Posted December 16, 2005 Share Posted December 16, 2005 congrats d-man! when can we see some frequency response measurements of these out in the garden? or in your room? thanks, tony Quote Link to comment Share on other sites More sharing options...
D-MAN Posted December 16, 2005 Author Share Posted December 16, 2005 when can we see some frequency response measurements of these out in the garden? or in your room? Hi, Tony. Well unfortunately not anytime soon, I'm afraid. I would have to pay someone to do it, and that's pretty unlikely for now... I could draw one, though, off the top of my head - that's pretty much what the industry does, ain't it?[] DM Quote Link to comment Share on other sites More sharing options...
DizRotus Posted December 16, 2005 Share Posted December 16, 2005 Congratulations Dana. Keep us posted on the issuing process. Quote Link to comment Share on other sites More sharing options...
D-MAN Posted December 16, 2005 Author Share Posted December 16, 2005 It has 6 more months to go before it actually issues. If someone can prove a case that it should not be issued because it either interferes with another patent or has already been marketed to the public, etc., then it won't.

ajsons Posted December 17, 2005 Share Posted December 17, 2005 (I draw plans for a living using AutoCad (drawings for electrical installations on navy ships, equipment fabrication, etc.). I t's amazing what AutoCad can do, but I also have great respect for our designers at work in the years B.C. (before computers). They produced beautiful drawings the old fashioned way, something I have trouble with). Those are excellent drawings, Dana. Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted December 17, 2005 Share Posted December 17, 2005 ajsons, I envy you. I can't get to first base with AutoCadd! I have been using old DOS Generic Cadd 6 here. BTW: Dana, FedEx tracking says you will get a care package Monday. Al K. Quote Link to comment Share on other sites More sharing options...
Deang Posted December 17, 2005 Share Posted December 17, 2005 "I could draw one, though, off the top of my head - that's pretty much what the industry does, ain't it?" Not quite, they measure everything possible and as carefully as possible -- and then they draw one off the top of their head. Quote Link to comment Share on other sites More sharing options...
sunnysal Posted December 17, 2005 Share Posted December 17, 2005 "I could draw one, though, off the top of my head - that's pretty much what the industry does, ain't it?" sad but probably closer to true than I would like to admit. warm regards, Tony Quote Link to comment Share on other sites More sharing options...
ajsons Posted December 17, 2005 Share Posted December 17, 2005 I thought they draw first, then measure. Al, I couldn't go beyond QuickBASIC, you used VisualBASIC for your software,' didn't you? (You're also in my book, on page 1....the crossover book). BTW, I started on the second set of universal A's, based on the scaling tips you gave me. I am also now seriously thinking about ESN for the low section. I am using EV drivers, though. Are there value changes I have to make?

Al Klappenberger Posted December 17, 2005 Share Posted December 17, 2005 Armando, No.. I only use BASIC for little quickie programs to investige equations I want to run over and over. All my software is written in ANSI "C". All my woofer/squawker networks are very flexable with respect to squawker drivers. The transformer taps will accomodate any driver that is in the neighborhood of 110 dB efficiency ragardless of 8 or 16 Ohms. That's most all good ones. The woofer should be a K33 though. The ES netwroks for designed to see 6 Ohms in series with 1 mHy voice coil inductance. It's not REAL critical though. Al K. Quote Link to comment Share on other sites More sharing options...

D-MAN Posted December 20, 2005 Author Share Posted December 20, 2005 Speaking of CAD programs, I did the drawings with CADSTD which cost $25. I can't figure out the "big-boy" CAD programs! DM Quote Link to comment Share on other sites More sharing options...
