Author Topic: D-150 Super Curvulon lens Christian Appelt Jedi Master Film Handler Posts: 505 From: Frankfurt, Germany Registered: Dec 2001 posted 02-12-2007 01:59 PM                     Is there anybody who knows the number of the U.S. patent for the Dimension-150 projection lens? It has been years that I held such a lens in my hand, and if I remember it correctly, there was a small engraving with the patent number. I'm just checking all available patents regarding cinema widescreen processes, but couldn't find the D-150 lens construction basics. I'd really appreciate your help.  |  IP: Logged Mark Lensenmayer Phenomenal Film Handler Posts: 1605 From: Upper Arlington, OH Registered: Sep 1999 posted 02-12-2007 07:39 PM                     D-150 Patent by Richard Vetter D-150 Screen by Richard Vetter I did not find a specific patent on the lens.  |  IP: Logged Floyd Justin Newton Jedi Master Film Handler Posts: 559 From: Phoenix, Arizona, USA Registered: Jun 2002 posted 02-12-2007 09:51 PM                     ...it's on the first link.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-13-2007 07:42 PM                     I have a very nice Curvulon here if you want photos.

I was under the impression that there was an own patent for the D-150 projection lens, and strange enough, I couldn't locate this patent although I did a search on Dr. Vetter in the US patent office database. That was really helpful!  |  IP: Logged
