You may be referring to Schutz cinema arc carbons, which are made in India. Inquiries could be made to:

SCHUTZ CARBON ELECTRODES PVT. LTD.
43, GIDC ESTATE
KALOL(N.G.) - 382 725
DIST. GANDHINAGAR
GUJARAT STATE
INDIA

I have it on good authority that Schutz carbons burn rather fast, but I have no personal experience with them.

Hello Gordon

Pleased to see you are still using quality products ....

Folks, for those who don't know Sandie, she is with Jack Roe Ltd. in the UK and sells, among other cinema supplies, Marble Double Eagle carbons, arc lamp reflectors, and a complete line of cinema supplies. Why not visit their site www.jack-roe.co.uk and get acquainted? [Smile]

Currently, I run a carbon booth from time to time and have been pleased with the quality of the Eagle carbons, though I don't have extensive experience with them. Carbon savers and Enarc reflectors from Marble seem fine, too.

The older nationals (pre-2000) are (were) fine, too. I missed out on the "fun" when National had a bad production run around 2000/2001.

Posted by Bill Enos (Member # 440) on 03-12-2003, 07:46 AM:

We received notice last fall from National and Marble that they were both making their final production runs and to order all you'll ever need. With the quality of the last we received from either, it's not much of a loss. I can't imagine there is enough of a demand to make manufacturing of carbons worth the trouble.

Posted by Gordon Bachlund (Member # 124) on 03-12-2003, 08:42 AM:

The Double Eagle carbons that Jack Roe Ltd. sells are current production from Japan, and still quite [thumbsup]

available.

I tried some samples of these carbons a couple of years ago. Found that they were slightly undersized and burned MUCH faster than the Marble or National. They were certainly cheaper, but that was offset by the rapid consumption.

I believe we used a total of one box of Schultz carbons at our drive-in... we quickly hunted down some more Marbles. I didn't get a chance to use them but the guy who did wasn't happy with them at all.

Posted by Gordon McLeod (Member # 33) on 03-14-2003, 09:37 AM:

Years ago I used Ibagawwa Sunny carbons and they burned very fast with a lot of soot and a very greenish light
I always found lorraine was the best in the superex sizes
Diamond was also a very dirty carbon
Has anyone ever heard of the chineese Seagull carbons

Posted by Gordon Bachlund (Member # 124) on 03-15-2003, 02:05 PM:

It is sad that Lorraine no longer manufactures carbons. Now that my curiosity has been piqued, I will look further into Chinese carbons, a quest I began several months ago but failed to pursue. The very name "seagull" conjures up thoughts of peculiar combustion residue!

Posted by William Hooper (Member # 71) on 09-17-2003, 12:49 AM:

Gordon Bachlund: Did you get a chance to test the Seagull carbons?

A theatre I work at is rapidly getting to the point where they must buy more carbons, & I'm trying to research sources & quality of carbons for them.

Who is still burning carbons, & where do you get yours? How do you like them?

Posted by Gordon Bachlund (Member # 124) on 09-17-2003, 07:38 AM:

William, I have yet to find a source for the Chinese carbons, though I am still looking.

I'd recommend you order from Jack Roe, Ltd. (see my precious reply) for now. You will be pleasantly surprised. [thumbsup]

We have been using Schutz carbons (7x8 trim) for about 2 years now in the 2 cinemas where we retained the carbon arcs.
Prior to that we used Marble Double Eagle until the local theatre supply people ceased to carry carbon stock.
Subsequently we imported the Schutz carbons directly from India.
I have found the burning rate almost the same as Marble, no real difference. However the Schutz carbons have a lower colour temperature than the Marble, so appearing more yellowish. Also we encounter the occasional negative which has a faulty core so the flame rises up and the light drops, but by closing the flame gap the flame descends and all is ok.
Overall we are quite satisfied with them.

Sandie wrote that Jack Roe doesn't have the 11mm x 17 1/2" carbons we need - closest is 9mm.

Cinema Equipment has Double Eagles in 11mm x 20".

Has anyone cut down carbons easily?

Posted by Stephen Furley (Member # 1277) on 09-26-2003, 07:04 AM:

Yes, only 7mm ones, but they were easy enough. Tried a hacksaw first, rather messy, and the teath tend to clog. I found the best way was to make a nick on one side, hold them down firmly on a sharp-edged table with the nick on top, and level with the table edge, and they break quite cleanly with a sharp blow. you need to hold the carbon down close to the break point, to prevent it bending, and possibly breaking internally at some other point.

Posted by John Pytlak (Member # 331) on 09-26-2003, 07:33 AM:

If you cut carbons (scoring and snapping the brittle carbon usually works well), consider using a drill to create a "crater" on the positive, or sanding a point on the negative. For copper-clad carbons, consider using a pipe cutter to cut through the copper and score the carbon:

FWIW I have been getting supplies of Sunny Carbons for the last 3 seasons from Carbon Imports, Christchurch New Zealand. I have only required 6 & 7mm carbons but they also stock 7 & 8mm sizes and possibly others if they are still being made by Sunny Carbons in Japan.
The Sunny's are now made by Daiichi Carbon Co Ltd Japan and since I switched to those I could not discern any difference between them and Double Eagle/Marble carbons which I used to source locally until supplies dried up. (I suspect that the supplier was up to their old tricks of forcing exhibitors to use Xenon lamps rather than carbons!!)
Since I discovered the NZ company I have been very happy with the rapid supply via the postal system with virtually NO breakages. Screen light was same as Double Eagle, slightly less consumption and if I mixed up a few carbons could not really tell what was on the screen without looking at the branding on the carbon. They were always well packaged and padded so travelled very well thru the post.
Best of all the cost was less than what I was paying for Double Eagle brand.
The contact there is Mark Strong on email, strongy@xtra.co.nz.
Suggest anyone who needs carbons to drop him an email and see what he can find for you.
My last consignment from them was 10 boxes of carbons and although it weighed a bit travelled OK.

PS, As to shortening carbons I have only ever snapped them cleanly by holding them with both hands and using the thumbs as a fulcrum and snapping the bit off I did not need or use.
It is quite easy to reform the crater of a new tip created by snapping carbons by just striking the lamp on reduced current (as normal) and let it burn for a few moments longer while the new crater "forms".
Once the crater is there go up to full current and you are away. No soot, no fuss, no splatter on the mirror etc.
An old hand that taught me always made the point that IF you ever dropped a carbon it only ever went into the bin or the slide arc. Being brittle things almost always a small crack would be created and the carbon would fail when the tip dropped off as the copper melted and ALWAYS it would be when you least expected it... like a reel change. [Eek!]

At the Stanley in Utica, NY we're using 11mmx20" carbons with Core Lite 135 lamps (working distance=29 1/2") and XL projectors.
It is close and if the carbon is too far back the shutter will cut the end off for you. I don't think you could use 20" carbons with Century projectors because of the shutter.

Posted by Stephen Furley (Member # 1277) on 10-03-2003, 01:17 PM:

There's a 'Stanley', no longer used as a cinema, in Jersey City. It's not a name I've ever seen over here. Who, or what, are they named after?

Posted by Robert Throop (Member # 61) on 10-03-2003, 02:49 PM:

The original "Stanley" was Stanley Mastbaum who had a chain of theatres called the Stanley Corporation of America. They were taken over by Warner Bros. in the late twenties. This later became Stanley Warner theatres.

Posted by William Hooper (Member # 71) on 10-06-2003, 01:20 AM:

Isn't it the Stanley in Utica which still has in the orchestra pit some kind of annunciator for the conductor to communicate to the projectionist desired changes in film speed?

I'd like to see photos of the Utica Stanley sometime!

The Jersey City Stanley is in *very* nice condition, although no longer a film venue. The Jehovah's Witnesses operate it now as a Meeting Hall, & have done a lot of restoration & some very nice, appropriate renovations such as carpeting, etc. The neccesary improvements in general lighting in the auditorium, though, could have been spec'd as something a little less, umm, institutional in color/coverage. They also did an addition to the building which from the outside plainly was the painstaking & successful to look original. I wish some of the folks who run PAC's had as much taste & regard for their buildings. Some of them don't know they're selling looks & functionality.

Posted by Robert Throop (Member # 61) on 10-07-2003, 09:53 AM:

There is a conductor's console on display in the lobby which has a speedometer display for film speed. I don't know if it was ever used since the Stanley opened in September 1928 and was equipped for sound from day one.
