hi all,
1270 umph, i dont know the word for. you take a rope, put it throug this little thing. then you pull at one end of the rope, and it can´t slip back, even when something is drawing heavily at the other end. "self locking"1274 hand held microscope or tiny telescope?
the others, hmm, no idea
greetings from germany chris
1274 dosimeter used to measure exposure to nuclear radiation. The charging unit is missing. They date back to the duck and cover days of the cold war and were part of radilocical survey package issued to the civil defense, hense the CD marking.
Best Regards Tom.
That's what I thought it might be but didn't know how it worked. Here's and explanation.
1271 is a device that is slipped over the head and neck of a cow. This prevents her from reaching through barbed wire fences and munching on grass on the other side of the fence.
My Dad also used the device on our milk cows. Since we always fed our milking cows grain when we ran them into the milking parlor he used this device to keep the milk cows from eating more grain by sticking their heads in the feed bunk and taking feed reserved for the beef cattle. The sharp points poke into the cow's neck when she sticks her head in between a feed bunk or wire fence yet when she is locked into a stanchion while milking the points on the yoke won't jab her.

TwoGuns fired this volley in news:6c7f2770-9b5a- snipped-for-privacy@c65g2000hsa.googlegroups.com:
model is resettable ("re-chargable" is the right word. It used a tiny version of a electroscope with a static charge to hold two filaments apart in a vacuum. Ionizing radiation would discharge them, and allow the filaments to close together. A graticule showed the dose.).

1274 is a dosimeter, several of which were part of the typical civil defense shelter gear; there is also a base-unit to reset the dosimeter (not pictured).
Yup. Mine has pegged on the high end after 40+ years since 'recharge', just from background.

1269) No idea on this one. Perhaps the holes at a given level are for marking off a specific number of divisions per inch. 1270) Some sort of load binder -- a strap threads through and around the smooth pulley. The serrated one swings in to lock it in position along the strap. 1271) No clue -- and not even a guess on this one. 1272) A hammer blow to the back marks the path of two grooves at right angles in wood prior to the grooves being cut by a chisel. 1273) Some kind of whistle -- perhaps to indicate overpressure in a steam engine? 1274) A dosimeter -- to tell how much radioactive exposure an individual has received. Obviously, this one is part of a Civil Defense kit which included one per user, plus at least one Geiger counter.
Now to see what others have guessed.
Enjoy, DoN.
1269 -- This would seemingly be used to trim something, perhaps photographs prior to mounting. The perforations on the arm with the sliding cutter seem to be arranged in inches, half inches, quarter inches, and selected eighth inches, and so would either make a measuring guide or a means for drawing parallel lines at whatever intervals are desired. 1270 -- This looks a lot like an oversized version of the mechanism many window blinds use to lock the height adjusting strings. I suspect it would be used to similar ends on a larger scale; the hook gets hung up (probably from a chain), and a rope is passed through the middle of the mechanism, where it works rather like a ratchet to allow something to be raised to a height but not lowered again until released. The "rope" may well be wire rope based on the generally massive character of the casting. 1271 -- Ummm...this seems to be a stand or support for something, adjustable to three different diameters of somethings. The unfolded picture is, I assume, of the something stand upside down, as the stops for the hinged parts would avoid collapse with it the other way around and the upturned bits at the far end of the extended arms keep the something from moving too far. The pointy prongs at the root of the forks are presumably to keep the something stand in place, either by driving them into wood or by letting them work into the ground.
What sort of somethings would you hold with one of these? I don't know, although I can picture a vessel like a cauldron or a frying pan.
1272 -- Possibly a marking hammer for indicating the owner of pulpwood logs (or any logs, I guess)? 1273 -- The body of this contraption appears to be a torch of some sort. Maybe it's a castrating tool to turn, say, a bull into a steer while cauterizing the wound in the same operation. 1274 -- This may be half of a cheap pocket telescope. 1275 -- Possibly a holder for birdshot for a muzzle-loading firearm? if so, I'd expect there must be a collection of a dozen or so end caps somewhere.Now to see other guesses...
1272 A log graders hammer?
Yes. It is based on the Leydon jar or electroscope. The device is an air-spaced capacitor, and the rate at which it loses charge depends on the electrical conductivity of the gas inside. Exposure to ionizing radiation ionizes the gas (doh!) making it more conductive. Usually there is a little scale inside viewable through the lense so that it may be read directly.
They were still used as late as the 1980s as they could be directly read without any processing unlike a film badge or crystal dosimeter.
I should say they were still used in the US. The Soviets pretty much never used them which is why the lost as many people a they did at Chernobyl. $10.00 each, dirt simple technology to save a life.
I have several sets of these, along with other rad detectors, which I keep in working shape.

I've got a couple of related ones. They have the HV friction charger built-in. One holds a charge nicely, the other leaks down fairly quickly.
Enjoy, DoN.
Friction Charger? Ive never seen one of those
Gunner
I have seen the piezo charger but never seen one with a buit-in charger. Could you post a pix of your unit don ? I would really like to see what one looks like.
If anyones intrested heres a link to what the hand held piezo charger looks like, it the one with the handle you squeeze.
Now thats way cool! Ive got a couple of the CD survey "kits", 3 different rad counters, plus dosimeters and whatnot in each, ...and buying lithium ion D batteries (long long term storage) got really expensive

"[L]iberals are afraid to state what they truly believe in, for to do so would result in even less votes than they currently receive. Their methodology is to lie about their real agenda in the hopes of regaining power, at which point they will do whatever they damn well please. The problem is they have concealed and obfuscated for so long that, as a group, they themselves are no longer sure of their goals. They are a collection of wild-eyed splinter groups, all holding a grab-bag of dreams and wishes. Some want a Socialist, secular-humanist state, others the repeal of the Second Amendment. Some want same sex/different species marriage, others want voting rights for trees, fish, coal and bugs. Some want cradle to grave care and complete subservience to the government nanny state, others want a culture that walks in lockstep and speaks only with intonations of political correctness. I view the American liberals in much the same way I view the competing factions of Islamic fundamentalists. The latter hate each other to the core, and only join forces to attack the US or Israel. The former hate themselves to the core, and only join forces to attack George Bush and conservatives." --Ron Marr

It is a cylinder turned by a knob which turns inside a dissimilar material to generate a high voltage static charge (very low current however). It is sort of like rubbing a glass rod with silk to generate high voltage sparks.
How do the separate chargers for the ones shown in the puzzle work?
Enjoy, DoN.

I would be glad to -- if I could find them. Right now, they are in the metal housing with the serious Navy surplus Geiger Counter (more ranges than the little CD ones, and a separate hand-held probe for the more sensitive ranges. (There is a second, smaller, tube inside the housing just behind a dimple designed to mark its location.)
Anyway -- I'll try my hand at ASCII graphics to show what they are like. Be sure to view with a fixed pitch font (like Courier) to avoid image distortion. +----------+ ++----------------------------------+ | || | | If anyones intrested heres a link to what the hand held piezo charger looks
and the one in the bottom middle with the black knob work in a fashion similar to mine. But they are a lot larger. I guess that these were for people who knew enough not to reset the one they were wearing in the middle of an operation. :-)
Speaking of CD -- are there still CD markers on any modern AM radio dials? :-)
Enjoy, DoN.
