CR4 Challenge #OU812

Viscosity or flow rate of ??? Still working on it. Wait, got an idea (ouch, that hurt). Get back to you later.

Does it have to do with heat and expansion?

No, and no.

Here's just some suppositions in attempts for backward redesigning of whatever it could be:

As it's glass so one can be used in high temperature conditions. To say, ambient temperature and/or ambient moisture measurement.

As it has rotating part one can be used in measurements for gas/air streams (depend on flowrate direction).

It would be filled by two non mixed liquids with visible boundary or liquid only and gas bulb.

Think someone here has better suggestions.

How about a scientific device to check what impurities are in the vapour of a liquid at a certain temperature!!

To measure Ph of water anywhere from 7.0 to 7.3. (maybe that is what the carton box states the ph it should have). Can be for checking Blower draft in " wc.

Any make available?

The box in the background has nothing to do with this instrument. It just happened to be on the bench when I took the photo.

Hi Bricktop,

Would you mind posting a closeup shot of the scale on that device?

OK, I'm at home now and the device is at work. I'll take a closeup in the AM, and post.

Will seeing the scale really make a difference? It seems close enough if you save the pic then enlarge. It starts at the bottom with 1.o and ascends incrementally but in reverse.( ie .9,.8,.7...). And the scale expands as it "rises". Curious.

Almost as if it is to "stretch" time as the liquid(?) rises in the tube.

"Will seeing the scale really make a difference?"

Yes. Especially if you can't see it.

It's made for some kind of liquid.

The second picture shows a vertical extension to the "tube" on the backside, but the first picture does not show it at all, which means the extension remains vertical, so it must be the entry point.

Once the liquid is introduced into the tube, it is rotated as needed, but is eventually left with the scale in the vertical position for taking the final readings.

The "bulbs" in the tube are for heating the liquid and/or gathering condensate or solids.

So, I guess it's not a thistlewick.

"So, I guess it's not a thistlewick."

Gerbil centrifuge?

has a look of a log scale

Yes, it looks like as vernier scale. But for what? Angle by readings where bulbs were placed?

I think it's rather something like two thermometers for humidity measurement.

The scale seems to be in terms of Microns

So it has to be a particle size measurement.

My current guess is a air analyser (never seen one , you see I am inside them , but never seen from outside ) or any other type of suspended particle size analyser, how it does it GOK must be some sort of a centrifuge mechanism

The guy who unpacked the thing thought it was an art-deco ceiling lamp. The mercury's on the floor.

Hi Europium,

I'm glad there are electronic solutions nowadays, though you would pay dearly for solutions that would measure as low as these things will.

Thanks (I'm assuming it was you) for the GA.

Mike

It's an Ace McLeod Gauge alright:

I also found the triple distilled mercury that goes with it.

Hi Bricktop,

What are you using it for? What range of vacuum are you measuring?

Mike

Well, the instrument goes back over 30 years. It was replaced, about 25 years ago for an electronic device.

We used to have a titanium vacuum melt operation. I only got to use this instrument a few times before it was replaced. It was an absolute pain in the ass to use. It was used to measure the signal from an impulse line, to calibrate a controller. That operation went away years ago.

My company has been around for about 125 years. The plant that I work in has been around since 1955. As instruments have become obsolete, they have been thrown into the "back room". Nobody can bring themselves to throw shit away. And I'm glad they didn't. Most of this stuff belongs in a museum. Shot of that, they make great CR4 challenges.

Whatever a "titanium vacuum melt" operation is!? I "got" to use this thing many times and, as I think I said in a post elsewhere here, it was, as you said, a pain in the ass. The sad thing is that we were using this 6 years ago in a chemical plant - we were doing so badly that we couldn't afford an electronic solution.

Enjoy your posts again now that I am back - I've been away for a while since I was laid off - took 6 months to find something else and had to relocate at that!

BTW, I think I get the prize since I beat Morgan 23 by 41 minutes. So what do I get? To keep my job? That's great because I'm still in the not-taking-it-for-granted stage.

Mike

Well, I gave you a GA, so, I hope someone will back me up on that, and give you a second. How about it guys? That would be post #17.

I threw my GA on there too, though I think points should be deducted for 'prior knowledge' and stealing your glory by robbing you of a truly wonderful bit of revenge over that belt tension thingy from last week

Ah, don't worry about it, I'm used to it.

two things comes into mind.

1.Perpetual motion machine

2.Device to show students vapour absorption cycle

Huh?

I was thinking it looked like something to measure static pressure in a ventilation system. or something like that, but then again I am purely guessing.

HOW DID YOU FIND OUT ABOUT THIS PIECE OF EQUIPMENT? This a top secret project of great commercial sensitivity.
This is a permanent motion machine. Filled with the correct formular liquid (Pats. Pend.) and with a strategically placed candle it will spin due to the alternating evaporation and condensation of the fluid (Pats. App. for). The output shaft, connected through the zero friction bearing (Regd. Des. & Pats App for) to an old car alternator will produce a guaranteed minimum of 3Kw/hr. Shares in this exciting project can be bought through my bank -Lehmann Bros.
My regards, Doodlebug.

Can you say RoHS? I should be dead from all of the times I pulled more (lead-based) solder off the spool with my teeth! Or all the methylene chloride fumes, or all of the benzene vapors, or all the cadmium chloride solutions I handled. I seem fine except for the alcohol....urp! (where's stinky pete?)

Mike

Oh, you ate one too? It should not have caused a vacuum though :>)

What ever is produced or distilled in this, try it with some orange juice. Watch your eye site. In prohibition times it would have been worth its weight in gold. I'll have a closer look later to see what I would do with it. Maybe Pineapple snaps? Hicks, Ky.

Is it a Bong?

Lawdys...! Poster 23 nailed it, and some knuckleheads voted him "off-topic"!!!

If you ever witnessed an autopsy, you'd know a "stomach contents seperator" when you saw it. It determines how many jalapenos and pickled eggs were consumed per every ounce of alcohol consumed.

NEXT Challenge!

Seems a termometer for temperature jumps,high precision, i knew 6 C temp.jumps full scale different to this, but may be.Filled with mercury.this have so big reservoirs..

I think I have seen something like that advertised in a Mens magazine. Must be the super deluxe version ;)

Too bad it doesn't have a V-belt drive, I'd loan you my tension tester.
