Posting from Rec.crafts.metalworking as always.
2143) Tool for deburing the other side of a drilled or punched hole. Drilled is more likely to have limited access to the far side. 2144) If the Pyrex logo is a round green color fired onto the glass, then it is some form of chem lab equipment. There is a lot which has been special modified for an unusual task.This may have started as a sphere with a single neck, and the other two were added by a glassblower at the lab in question. Given the angles of the necks, I suspect that it was for reacting at least two gasses, and drawing off the results in yet another direction.
If it is such a modified piece of labware, it is unlikely to have a specific name.
It does look to have plain necks, not the ground glass fitted ones for coupling directly to other glassware -- so whatever it reacted probably would not attack rubber stoppers.
2145) Lots of possibilities -- most of which would be supported by the presence of markings on the box somewhere.It looks as though the two binding posts are not on the standard 3/4" center to center spacing, so I suspect that it was someone's home-made product. (The reason for the standard spacing is so standard dual banana plugs can fit into it, not needing a separate connection to each post. The posts will accept banana plugs, wires (through a transverse hole under the knobs) and fork terminals.
The fact that two different colors of binding post are used suggests that it is polarized - but it may also simply represent what was available from the piece of equipment which was canibalized to supply the binding posts. These are the cheap ones which were used on Heathkit equipment, and likely from Radio Shack stores as well.
I don't see the normal insulating mounting spacers, so the box itself is likely plastic, not metal -- unless it is a dummy device not really intended to be connected to.
What is there could be:
1) A standard cell (1.0194V or so) -- but there should be a marker to not turn it upside down. (Standard cells really have to sit on a shelf forever undisturbed.) 2) A standard resistor (no need for polarity there), but there should be a marking showing the value. 3) A standard capacitor. If electrolytic, the polarity markings from the colors of the binding posts is useful, of course. Again -- no markings to show the value inside. 4) A battery (polarity makes sense there, of course), but again, no markings. And -- no obvious way to replace it, though the bottom could be open. We don't see that view, so we don't know. 5) Intended to look like an explosive device. 6) Something which I have not yet thought of.2146) Some kind of trap or remote-release cage. I note that the floorboard appears to be under stress, which might be used to shoot the door open or closed.
2147) Looks like something designed for rolling a groove between a curbstone and the grass alongside it -- or alongside a sidewalk or driveway.2148) Looks like something designed to measure some characteristic of a gas -- and to adjust the flow of it. It looks as though the meter dial is marked in percent, and it appears to be an electrical meter of some sort.
There is a hose barb on the right. The left might be an adjustment knob or some form of calibrating plugin.
There is an old mil-standard connector on the other end of the cable.
I don't know whether the hanging loop pivot does anything else as well -- since it appears to be knurled for either adjustment or field removal and replacement.
Now to send this off and see what others have suggested.
Enjoy, DoN.
