    I wouldn't be at all surprised if it was filed as one of those "employee
    incentive" programs whereby the guy who thought it up got some small kickback
    from NASA upon the patent's approval...

    Maybe I could patent a Panavise as a unique means of holding a circuit board
    during soldering so as to avoid having it shift around during work...

    I've patented degress 45,48 and 33. Feel free to use the rest, though.

    Oh come on..Patent 4975672 (keeps windings from touching) .it's not
    that bad of an idea....

    I see these benefits
    * Neat looking windings for DIY inductors
    * low capacitance
    * high voltage
    * uses cheap plentiful uninsulated bus wire or just any stripped wire.
    (Everybody knows Digikey doesn't sell magnet wire...)
    * can be made with cheap laser cutting

    It's just funny that I've never seen it used anywhere nor thought of
    making a wire guide.

  6. The problem isn't NASA, it's the "tax dollars".

    Thanks,

  7. McLynm or whatever is the author of a few books on magnetics. Sort of
    cookbookish.

    Cheers
     

  8. That IS funny!

    He says bare wire then says put it in a shrink tube. What an idiot,
    and how stupid is the patent office!?

    What is a "single strand of Litz wire"? Bwuahahahahah!
     

  9. Damn. You actually said soemthing radically funny. You should have
    said *radially* stupid, however.
     
  10. There have been spreaders around for decades.
    Be better if good ol fashioned high strength mag wire were used along
    with whatever else got incorporated to increase breakdown resistance.
    That is the shittiest part of it. Much better quality wire is in the
    channel and readily available.
    But MOUSER DOES!

    Can be made even cheaper than that with aramid paper and a pen knife.
    I have. Working in the modern PS industry for ten years allows one to
    have seen a lot of different applications of the art.
     
  11. An idiot like you should have to pay MORE!
     
  12. The best way to cheaply insulate a small toroid is to wrap it with
    transformer tape like the old tires used to be before winding onto it.

    1) You are a little late to be harping; the date of the patent is 1990.
    2) *NOTHING* in the claims states bare wire; in fact it eXplicity (ie:
    X-rated) states *Litz* wire.
    3) Learn how to read.
     
  15. The manner, not the media, fool! Not that I didn't know you pulled
    that shit on purpose.

    That'll teach me, huh!? :-]
     

  16. Actually, it states "a single strand of litz" which is pretty funny.

    I didn't the read patent. :)
    Patents often have that pseudo english patentese that I don't like
    reading.
    What?? No claim of using bare wire in the patent???. :)
    I just looked at the diagram and used my imagination...
    The wire guide really looks useful to keep windings from shorting out
    with bare wire..
    Litz wire makes sense for HF use.

    Those steel belts tend to be lossy at higher frequencies.

    Speaking of reading, try "NASA Tech Briefs." It's stunning the number
    of insane/inane patents they generate at our expense.

    Your argument is circular.
