[Cameramakers] Cirkut camera
Hello: If there are patent numbers, you can probably do some research on US patent database. You can't search the old stuff by keyword, because the patent pages are saved as .tiff files. I had no luck with this aproach myself with either the Fairchild cameras/shutters or the Graphic focal plane shutter (the former had no patent numbers, and I couldn't find anyone who could check their camera for patent numbers for me (or forgot to get back to me).

[Cameramakers] Cirkut patent numbers
Ah, I see further down in the digest someone has provided some patent numbers. I go to www.uspto.gov It takes a little while to figure out how to use the website. There is a download link there for a plug-in called alterna-tiff, which will allow .tiff files to be displayable in a browser. It will also allow you to save them to disk as individual pages. Patents run anywhere from 30-130 kB (approximately) per page, so long ones are tedious to download, but if you want to look before deciding to order them, it's great. I have patiently downloaded everything I want a page at a time and print them out on a laser printer. I haven't paid for any yet. You may need help from the reference librarian at a patent repository (like OSU, or whatever site handles it locally in your area). They can help you find patent numbers associated with the class numbers that relate to the item. If you look at one patent, right after the description, there is a class number. This is something to keep track of too if you want to find related things. The patent librarian I spoke with gave me a weird example - he said that electric shavers fall under some same classes as 'harvesting' equipment. This is what takes so %^@#%^ long to get patent applications processed, I guess. Murray ___ Cameramakers mailing list [EMAIL PROTECTED] http://rmp.opusis.com/mailman/listinfo/cameramakers

Just for fun you might want to also look at: 4,431,289 Reinhardt Panoramic Camera 4,241,985 Globuscope Panoramic Camera I am sure there are others but have run in to the same problems with the index system.

[Cameramakers] Projects
Hi Everybody,,, I have just subscribed to your list ... I am in the processof building several photographic items... The things I hope to be buildingis a 8x10 camera with a 6 foot bellows, a light weight 20x24 camera with a48 inch bellows, and a 10,000 watt 11x14 Ultraviolet enlarger I willtry to read over your archive before I start asking stupid questions...I will post a few things that I have found to be interesting that I amconsidering incorporating in my projects... Two of the things that I amthinking of using in the cameras are found at :http://www.mcmaster.com/ You can access the items from this home page...Cross Block:Item #9268K85 (on page # 1066 Item #17) the item is a plastic or stainlesscross block... I thought this would make a great item to fasten the frontlens plate to create the front standard using a 1/2 rod to be usedfor rise and fall and front to back tilts.Rail with locking platforms:Item# 60585K41 rail and Item# 605K522 slide and hand brake... I thought this would make a good low cost optical rail with adjustablelocking platforms to mount the front and rear standards on... as well as thetripod mount I have never made a Large format camera so any suggestions , input orcriticisms would be appreciatedWeight will be a big factor... John
