I remember seeing some of these designs in the late 80's, supposedly added some stiffness....but the trend never caught on. I believe they were generally marketed as TT or Tri bikes, I even remember Nashbar was selling them for a couple of years.
Those are often called "Hellenic" stays and were used a long time ago by Hetchins in England. They also appeared in the 80's on the Colnago Master "Equalateral" and on some Raleigh pro team bikes, as well as some GT frames in the 90's. However, I suspect the OP is referring to something else, but I think we need a little better "word picture" to suss it out, especially if a picture-picture is not forthcoming.
