Another CR4 Challenge - #1269

Damn, but we are in trouble if the Cat doesn't know.

It makes dry ice cakes when hooked to a source of CO2.

Hello Bricky,

It looks like a grinder to me. Maybe connected to an air line perhaps?

Spray dried coffee?

Take care and happy holidays......................

But would a grinder or grinder nose piece (attachment) be a "very common piece, (still) widely found in the industrial world"? Or even in the non-industrialized world...where plastic has yet to replace cast iron?

Whet does this device do?

Is that a typo, or a subtle hint? As in a sharpening device? Or are you trying to see if anyone is sharp enough to pick up on it?

It's a typo.

Flush away. Loo operator.

Used to pack bearings with grease?

Looks like an adjustable pressure relief valve to me with a manual release, but without hands on I would not make a wager on it.

I'm with you. Some type of pressure venting device. I was leaning towards steam release.

Once again I am late to the party. No invite.....hmmm. <conspiracy and paranoia increasing>

I am starting at the beginning and reading my way down. I am on the PRV boat.

I shall read on to see how it all works out.

My guess is: It's used to sample lubricating oil as in diesel engines or transmissions.

Judging by the size, pepper grinders look almost the same, so since it is bigger I guess a coffee bean grinder!

Hello DDjames:

At first I thought it looked too 'engineerish'? But it could look that way with age?

I am on your side, I think it could be a coffee grinder. Though I would like a better close-up before I would let my coffee be ground in it! But, the original Italian aluminium percolators look like that after a few years?

This is a 'goodun' for sure!

Take care and have a wonderful holiday......................

My second impression was something to do with a steam locomotive control, forward reverse setting on the side with vent, and engage/dis-engage under top cover.

Sausage skin extruder??? Mounts on mouth of the grinder or whatnot?

adjustable relief or bleed valve?

It would appear to be some sort of extrusion device, for a fairly viscous material. Except the vent on top has multiple openings. Square noodles? Never mind...

Hi Bricktop,

Will you explain us what the device do? I ask to some experienced engineers at the company I work but none can answer me.

Regards

Ernesto

The guest in post #3 nailed it. You hook it up to a CO₂ cylinder, and it makes dry ice pucks.

Here's what the modern units look like:

Hello Bricky,

I would never have guessed that! You gave us a 'goodun' there, thanks.How fascinating!

Have a happy holiday....................

Thanks BB! I have more to come. I'll post another tomorrow. I'm cleaning out the "back room" at work. I just can't believe the very outdated, (and very expensive), stuff I've found, that is pretty much useless today. (However, I'm holding on the the dry ice maker. We used it to chill down acetone, to calibrate thermocouples, for the deep freeze. We outsource that now).

Dry ice can be really fun. I know some funny pratical jokes to play with it. Anyone else?

Then you get a GA lyn. I hope someone else backs me up here and gived you another.

Done, gladly Lyn was swift and sure in his response.!

This one was quite fun.

Thank you all !!!!!!!!!!!!!!

Okay. Tchnically I was wrong. However the inverted PRV would be sort of....nevermind.

So why in Petes petunias do you have one of these things lieing about anyway.

Oh yeah....I just thought of all the "usefull" crap in my garage.

I would have gone with the coffee grinder. Show me an engeering office in an industrial setting that doesn't have a coffee pot!

I just thought of a few new markets for this device. Anyplace where injuries could occur but the owners and operators don't want to or can't pay for the refrigeration or storage needed to keep ice on hand. Sports arenas, factories, construction sites, and mines are some of the possible candidates. Someone sprains an ankle, let's say, and a trainer or supervisor makes a few dry ice pucks to apply to the swollen area.

It'sa die or compression punch of some kind, humm?
