Fellow Shadow Watchers,
Requests for the JPEG of the Pilkington/Gibbs
heliochronometer are coming in with each posting.
I'll wait a day or two and send it out in one mailing.
Apologies for the delay - but it's worth waiting for!
Tony M.

I am no expert on U.S. or international
patent law. However, if you are

description or "disclosure form".
Keeping in mind that patents really only
give you greater force in pursuing (and
paying for) a law suit, consider what
Hi Tony:
I'm not familiar with this dial. You don't happen to know where we can see
a picture of the Pilking Gibbs heliochronometer do you; if not, how about a
brief description? Why is it so expensive? I bet because it's all
hand-tooled by you! If this dial were mass-produced using a differen

spring. It is solid bronze and will weigh about 70 lbs. The focusing

Hello Listmembers,
I have been watching the list quietly for some time now, and I
think I can contribute to the recent "patent and copyright" thread.
I have been responsible (to date) for 5 concepts which
