More Mystery Items

[jfgw]

Here are ten items for you to identify. All images are mine.

1. This is the same size and shape as an ordinary 100W light bulb of the type that us older folk were brought up with. Can you enlighten us as to what it really is?


2. What is this?


3. It has a wheel or roller each end but what is it for?


4. What are these two brass items?


5. What are these blue plastic things for?


6. Two metal clips, but what are they for?


7. This can be adjusted to any angle from 0 to 45 degrees. The moving arm is slightly curved and allows for fine adjustment by sliding the part with the spirit level. There was writing on the slotted part but I have photoshopped it out. This looks like it could have a multitude of different uses but what was it made for?


8. What is the purpose of this odd-looking tool?


9. Do you know what this is?


10. What would this be used for?

[eepee]

I'll start it although probably all wrong!!!

9 A bleed valve although unlikely to be from a domestic radiator.

10 A high voltage divider probe?

Is [2] a Geiger-Müller tube?

[1] is obviously run hot... too big for an oven light, so heater for hatching chickens, growing spliff etc?

[malkymoo]

8 is a tool for screwing up conduit bushes.

Some of the others look annoyingly familiar, just can’t bring to mind what they are!

[malkymoo]

Just a guess- are 5 tile spacers for hexagonal tiles?

9 A bleed valve although unlikely to be from a domestic radiator.

Correct answer eepee, although they are used on domestic radiators. This one, with a thread diameter of 7mm, is specific to the Myson brand.

10 A high voltage divider probe?

Not a high voltage divider probe. Note that it has a clip at one end and a probe at the other.

Is [2] a Geiger-Müller tube?

An interesting guess but not a a Geiger-Müller tube.

[1] is obviously run hot... too big for an oven light, so heater for hatching chickens, growing spliff etc?

Not a heater, and not for hatching or for growing anything, legal or otherwise.

Keep the guesses coming in!

8 is a tool for screwing up conduit bushes.

Correct answer malkymoo. There is a picture here, https://cktools-superstore.co.uk/Condui ... ench-T4755 . It can be used to tighten bushes where there is not enough room to use a conventional spanner.

Just a guess- are 5 tile spacers for hexagonal tiles?

Correctly guessed! They are tile spacers for hexagonal tiles.

[2] photomultiplier??

[jfgw]

[2] photomultiplier??

I see the likeness but it is not a photomultiplier.

[eepee]

I'll try again!

10 A probe for electrostatic detection such as with a leyden jar.

10 A probe for electrostatic detection such as with a leyden jar.

Slightly warmer but still cold.

7. Looks like it is used to measure the angle of a surface to the horizontal plane. For surfaces up to 45 degrees, the face marked "D Sub" in the photo would be placed on the surface and the angle determined by moving the spirit level arm until the bubble centres. For surfaces with an inclination above 45 degrees the face perpendicular to "D Sub" would be used and 45 degrees added to the measurement obtained from the instrument.

However, quite what surfaces have a requirement to be measured to a level of accuracy of degrees and minutes (as opposed to just degrees) is beyond me. Some sort of machined components perhaps?

10. To discharge capacitors prior to working on stuff (croc clip to deck, resistor in probe)?

2. Electon gun? Klystron? Antigravity generator?

[swill453]

Yes I think 7 is a clinometer, but it looks like this one has a specific purpose/application that I can't guess. Is more needed?

Scott.

[eepee]

One final stab at 10.

10 Continuity tester, probably buzzer based ?

It is a clinometer. These are also known by another name which gives a huge clue as to their specific function. The text on the slotted part includes the manufacturer, the year and a number.

It is used to measure or set the angle of something but what?

10. To discharge capacitors prior to working on stuff (croc clip to deck, resistor in probe)?

Getting warmer.

2. Electon gun? Klystron? Antigravity generator?

The internals look a lot like an electron gun but an electron gun on its own is not much use; it needs to be part of a bigger component.
It is not a klystron.
It is not an antigravity generator, ectoplasm vapouriser or a love-beam ray gun*.

10 Continuity tester, probably buzzer based ?

Not a continuity tester. There is no buzzer or other type of indicator.

*I did build a love-beam ray gun which caused women to immediately rip their clothes off and make mad, vigorous love to me. Unfortunately, when I went to use it on a rather nice-looking member of staff at a local old people's home, the switch developed a fault and the machine kept firing indiscriminately at the residents.

Is 2 a tuning indicator?

[jfgw]

Is 2 a tuning indicator?

Known as a "magic eye". An interesting guess but, unfortunately, not correct.

It is used to measure or set the angle of something but what?.

I can imagine 7 being used to set or measure the gradient on railway tracks. Mounted on a bogie, and used to ensure a constant gradient on climbs and check for settlement of tracks.

Another interesting guess but still not correct.

This is a genuine antique but they were still used this century (and, to a lesser extent, may well still be used today; I am not an expert in such matters).
