Mystery tool, what is it?

[shiber]

I picked this up at an auction and don't know what it is. It has some lights inside and a screen on the front, kinda looks like you would put something over the screen and the light would help to see?

Any ideas?

Looks to me like it could be an old xray viewing screen. I think I remember seeing those in the Dr offices.

I think so

 

[shiber]

It came from a machine shop that did aerospace work. Thats why I thought it might be for looking at drawings or something.

 

[Oldtuleguy]

Nothing on the web. Looks like a cool gizmo. Does it work?

 

[garfunkle24]

Wondering if the slot/aperture on the top right is for microfiche?

 

[shiber]

Oldtulguy, I need to get a couple bulbs to see if it works. Guess that means I havent tried it yet.

Used for confirmation viewing of U2 film/photos before sending them up for verification.

 

[shiber]

thickhead, please explain. I'm googling it and not coming up with anything other than u2 rock band

 

[thickhead]

Lockheed U-2.

 

[Oldtuleguy]

Lockheed's u2 spyplane

 

[thickhead]

Sorry. I was just messing around. Jim Beam made me do it.

 

[shiber]

OK Thanks... I'll keep looking. Maybe I'll get some help from Jim Beam

It is an xray viewer.

It is how they inspected weld joints in the old days...(and still do). You place photographic film on one side of the area to be inspected....then put a radioactive source (pig) on the other side. The Pig is a steal enclosure they tech can open up from a distance.

After the film is exposed, a tech reads the film using the above as a light source to determine if the weld is good.

That method is still used for steal pressure tanks.

I like the spylane idea better!

 

[ZRX61]

Company is still in business, call em up.

 

[ddawg16]

I like the spylane idea better!

The U2 was metal....so I have no doubt it was used to inspect AL welds.

 

[RTM]

Lyman e Eddy company is referenced in a 1982 book on non destructive testing, specifically for leak penetrant tests. Snippet view on google books.

Agreeing w DDawg

But you can use it for drawings if you want, slide sorting, shadow puppets....

When I pipelined back in the 90's they used a thick lead box about the same size as those small ammo cans in which the radioactive source (the pill as it was called on the pipeline) resided in. One end of the box has about a 15 ft long cable with a crank on it that when the're ready to x-ray opens a door and pushes the pill out through a 15 ft flexible cable on the other end to the weld. The film is then exposed for so many minutes then they crank the pill back into the box and the door closes behind it. The reason for the 30 ft of cable is so the tech is not exposed to radiation. Each time they x-ray they cordon off the exposure zone and the techs job is to keep people out of the danger Zone. There are some urban legend storys about the pill falling out on the ground and some guy comes along and picks it up puts in his pocket and dies almost immediately . That's the basic version of story I always heard. Who Knows? I know X-ray technology has changed things a lot but I'm not up on it anymore.

i had some trouble visualizing that, so i googled it

bet those were fun to license after 9/11

I took a look at that website you pulled up and read they use depleted uranium which is apparently very heavy (45 lbs of it inside a small ammo can sized lead box to shield the radioactive pill. That stuff must be more dense than lead.
Most of the ones I seen out on the pipeline were pretty similar in size to the one above.I've been on power house jobs where I know some of the X-Ray equipment is big enough they lock down and secure the whole the building. I only seen one of those and it was like milk crate size but they had it on a big cart and they acted like it was quite heavy. Didn't take me long to figure out I wanted as far away from that as possible.:shocking

 

[Provincial]

Depleted Uranium is 59% heavier than lead, for the same volume! That much more dense, to put it another way. That is why the Army uses it for tank cannon projectile cores.

 

[driftpin]

I believe the A-10 'Warthog' uses depleted uranium for tank-buster armor penetration.

My PCP uses one of those x-ray viewers in his office, I get to see it every time I get a chest x-ray. Same co.

Of no use as far as nuk weapons go....and it would take a long exposure to kill someone with the radiation...

 

[38Chevy454]

That is a radiographic viewer. AKA x-ray film viewer. That adjustable hole is to check a small area. Generally you hang the radiographs and view the whole image. If a question on an area, you use the spot viewer. The internal lights are very bright inside the unit.
Itself is not radioactive. It's for viewing the film once the film was exposed.
Long time past I was a radiographic inspector. I viewed casting radiographs, but almost anything can be checked. Such as welds mentioned using a portable radiation source.

Thank you very much 38chevy454, I really appreciate your insight.!!!!
