morse contact printers
"Richard Knoppow" wrote
I found a bunch of [specialized argon] lamps at a ham radio swap meet a couple of months ago for a dollar each! I don't think the guy selling them knew what they were. I find rarities often go for a song: people looking for the thing are rarer than the thing itself. I have a job selling a huge collection of antique medical quack devices. When the right buyer can be found some of the items go for $20,000. As an experiment I tested the waters on ebay and it looks like the collection would go for ~0.05 on the dollar. Collectors know this and there is sniping and collusion aplenty. At any one time there are 10-20 active well healed collectors and they all know each other. It is going to take longer to sell the collection off [at sane prices] than it took to collect it. -- Nicholas O.

Nicholas O. Lindan spake thus:

One hopes they don't become re-injured ... -- Just as McDonald's is where you go when you're hungry but don't really care about the quality of your food, Wikipedia is where you go when you're curious but don't really care about the quality of your knowledge. - Matthew White's WikiWatch (http://users.erols.com/mwhite28/wikiwoo.htm) |

I have experimented in the past with photolytic images from sunlight on conventional printing paper. They are not strong but appear. it will be simple enough to try it with the printer. I wonder if we are talking about two different kinds of printers. I don't know if Morse ever made plate burners but what you describe sounds like it might be one. Richard Knoppow |

I wonder if we are talking about two different kinds of printers. I don't know if Morse ever made plate burners but what you describe sounds like it might be one. Richard Knoppow Well, I tried this and was astonished to find it worked! I tested with a sheet of enlarging paper placed on the inner diffusing glass with some opaque cardboard under half of it. I gave it ten minutes. The exposed end was quite purple. I didn't use the top glass plate because it is not original on my printer and has significant UV absorption. I presume the original plate was clear glass rather than green glass with much greater UV transmission. The attenuation of UV on mine is probably actually an advantage since exposure time is very short. Previous experiments with photolytic printing using ordinary developing out paper suggest that the Morse printer _would_ probably print POP in a few minutes. POP is still made by Kentmere in England and sold in the US under the Centenial POP name. For those not familar with POP it is printed directly in sunlight. The image is not permanent unless treated in toner and fixed. The original image color is a sort of purplish brown but it can be toned to many colors. -- --- Richard Knoppow Los Angeles, CA, USA -- Posted via a free Usenet account from http://www.teranews.com |

So what ever happened to the house-cleaning that initiated this thread?

These are 10x10 units with 39 argon lamps in each. Each lamp is individually switched. Anyone interested? I don't know how old this post is, but I would be very interested. Please contact me if you still have them Be interesting if its recent. I have a Morse printer, they were designed for printing aerial film. They were intended for printing on very slow contact paper and even for that have exposure times on the order of a few seconds. Morse also made a larger version of this printer. You can inflate the pressure pad with a bicycle tire pump but be careful because it doesn't take much air to get it right. -- -- Richard Knoppow Los Angeles WB6KBL |
