Has anyone heard of this?

Also, I'm a little confused on the Union Carbide/Lorriane relationship. I thought Union Carbide bought Lorriane many years ago, then sold off the whole thing to a Japanese company in the early 1980's. Is that what happened?
 

Marble makes carbon in Japan Double Eagle brand as does Ibagawwa under the brand Sunny
There is an Indian carbon company
here

and a chineese one called SeaGull

I don't know what happened to the Ringsdorf group that made Diamond carbons

As for National the projector division was closed down and it has lost all the people who knew what they were doing so it is iffy what they will produce

>Dear customer, National Electric caron Products has been in the carbon arc business since 1892. We were pioneers in the industry and we received an Oscar in 1956 for providing true "outdoor" lighting on an inside movie set. Arc carbon at one time, was onr of out highest output product lines with hundreds of customers and a growing stable market. As time has evolved, technology has changed the need for these products. We have seen steadily declining salesfor the last five years as the markets have moved to other technologies available.
As such, we will be discontinuing production for Carbon Arc at the end of 2002. We will accept orders up to December 31,2002. We are offering several options to meet your needs.<
The letter goes on to describe various plans for purchasing remaining stock,prices etc. So I guess it is time for me to bite the bullet and get some lamphouses! But I will miss the light of the arc.
If anyone needs a full copy of the letter feel free to e-mail me.
 

I have purchased carbons from Jack Roe without difficulty.
 

According to the City of Tucson, AZ, the EPA has put a nation-wide ban on the indoor use of carbons.

The Tucson Convention Center (Tucson Parks and Recreation) used to have some nice Strong Super Trooper Follow Spots that were removed because of this "ban". These units are now occosionally used for outdoor events. The City of Tucson "stage handlers and sound crews" are so well trained that they are using welding carbons in these units! They have no idea what projection carbons are...and those that they had on hand were pretty well beat up! I tried to tell the City of Tucson people that their info was incorrect, but of course you cant get anywhere when speaking with political boneheads. I also tried to speak with them about the correct operation of these units, and of course they are clueless.I also asked them to present me with the EPA regulation banning the use of carbons, and of course they were unable to do so. I have not checked the EPA regs...but I understand this "ban" to be nothing less than a well circulated rumor. Any comments anyone?

There is a local "art house cinema"...if one can even call it that. Anyhow, the owner of this "theater" managed to save a pair of Supers/SH1000s and Magnarcs from the Tucson "Temple of Music and Art". Those boneheads where clueless as to what this equipment is and were preparing to haul it all off to the dump. Anyhow, I offered to to the install for this "arthouse"...a 16mm "art house". The owner said that the City of Tucson would not permit him to run carbons indoors. This owner is one of the many boneheads that I spent much time consulting with...and was nothing less than a waste of time. I offered to get him some Xenon so that he could run 35mm...no response from the yutz.
 

does anyone use seagull carbons? i heard some first hand accounts about how much they sucked, but i have used them a bit in the past few months with no problems.
 

I did try to explain to the City of Tucson about the need to vent both carbons and Xenon. Needless to say that I got no where with these boneheads. They insist that the indoor use of carbons has been banned by the E.P.A. period and end of sentence!
 

Back in my student days we showed a rereleased new print of The Big Sleep. About two days before the show I got a call from the University's health and safety officer telling me that 'old cinema films' were a fire risk and that we couldn't show it. I patiently explained that this was a copy on modern, non-inflammable stock and that nitrate prints have not gone anywhere near any cinemas for almost half a century (apart from one or two specially licensed ones). But he wouldn't believe me, and in the end it took a 'phone call from the distributor to get him off my back.

Note, safety will burn, just slowly. Nitrate goes up in a big orange flame with a slight "whoosh" sound.

Better Projection Pays!

(Kids, don't try this at home!)
 

Moving back to topic (almost), the non-profit Landmark Loews Jersey Theatre is always looking for donations of 13.6mm carbons, if anyone happens to find some laying around.

Basically, if you can see any 'nitrate' edge marks on an element and the release print stock mark indicates the year of manufacture as being 1950 or earlier (and make sure you are looking at the stock mark of the release print stock, not an earlier generation), then assume it's nitrate until you've tested it.

I agree that this Monogram print is probably acetate, because acetate base has almost identical combustion characteristics to paper. If water will extinguish the fire, it certainly isn't nitrate.
