the official "can you identify this mystery thing" thread

auminer and tzrider are correct but of what.
hint - this is pre repair

...
freddie, where did you find my socket?

 

ACL and Meniscus

 

Right shoulder. The white area around most of the edges is where the tendon tore loose from the humerus. Some of the ragged 'strings' were trimmed off. sutured with
some sort of metallic thread and tied to a screw implanted into the bone. Pull tight and wait for tendon to reattach to the bone. Those 4 strands all went to the.one screw eye.
Not all tears are this complete. This was a full tear with retraction above above the joint

 

That looks painful.

A little bit o' safety wire, some lock tabs...it's all good.

 

The surgery wasn't to bad - general anesthesia. PT was difficult but well worth the effort

 

PT saved my left wrist and, yeah, difficult on many levels.
It was no accident that I had some of the top surgeons in the field straighten out the damage, but it was the PT that ultimately ensured the success of the repair.
The distal end of my radius was shattered over ~2" and all the bones in the joint were displaced. 3 plates, 8-9 screws and 3 pins were packed into a ~3" x ~1" area to put the radius back together. If it weren't for the PT, the joint woulda fused into uselessness. Soooo lucky.

 

no idea but thinking tavern puzzle of some kind. Sent from a friend who claims this thing has been around her parents house for years but no one has any idea what it is. Lol

 

Is that a lever on the bottom right? Does it do anything?....

 

It's the missing piece to this

 

"There's a mechanism!!!"

I'd guess an Astrolabe.

 

Is this that the analog computer that's over 2,000 years old? IIRC, they finally figured it out using imaging that penetrated the corrosion to create scanned parts that they then virtually assembled.

 

Yep

My dad helped raise the money to get the one that's in Mariner's Museum.

 

Possibly some sort of counting mechanism?

 

Fire Sprinkler

 

Probably filled with Carbon tetrachloride....nasty stuff.

 

Sure gets those stubborn stains out though.

 

Close, not a sprinkler. Called a fire extinguisher. The bulb contained carbon tetrachloride which when released would cause phosgene and of hydrogen chloride gas which was toxic. So if the fire didn't kill you the extinguishing agent would. The bottom is a spring loaded trigger which was designed to thermostatically release at 160 degrees due to the melting of the solder. They would hang these in a grid pattern in the facility and call it good. I still find them occasionally in older buildings and once I tell the owner what they are they can't wait to get rid of them. LOL
