Have you ever seen this symbol ?

I think I saw it (or something like it) on a cirquit diagram in the
1950s. Any idea which component it is? (I am not an electronics pro).

Thank you

Could be a tapped inductor, but it's a bit hard to tell, out of context.

I don't think it's random access memory, although it does look a little
like Aries (the RAM).

Thank you. If anyone could point me to a URL that shows a similar
symbol, I'd much appreciate it.

Maybe a variant of the Greek character Upsilon w/hook?

It could well be. Can you tell me what that symbol would be used to
denote in 1950s electronic schematics?

Thank you

I can't recall seeing that symbol on a schematic. Could you scan and
post enough of the schematic containing the symbol and post a link to
it to give us a clue?

As someone else suggested, it looks like a very small winding of a
transformer, possibly center-tapped.

Show us the symbol in context of a portion of the diagram.

I wish I could. I am going entirely from memory. I think the symbol
may have been enclosed in a circle, like transistor symbols are. I
also think there was a bit more to it than what I drew. there may have
been a short line crossing the central vertical line, or something.

Now that you've said that, chances are high that you're never going to
get a *CORRECT* answer. Lots of guesses, for sure, but no way to know
that any of them are right or wrong.

Without knowing *FOR SURE* what it's supposed to look like, as opposed
to your now-known-to-be possibly faulty/erroneous drawing from memory,
it could be literally ANYTHING, from a block-diagram symbol for
"turbocharged V8 engine" to a loose eyebrow hair that fell on the
original drawing while it was being made and then somehow got propagated
into future copies, to a hobo-cant "Avoid this house - owner has vicious
dog and shoots at hobos" symbol, or an ancient etruscan glyph meaning
"god" - there's simply no way to tell that doesn't involve guessing,
with no ability to verify the guess as right, wrong, or otherwise.

Lack of context is also contributing to making it much more difficult to
pin down what the intended/correct meaning is - were it shown as part of
a circuit, it might be possible to figure out "It has to be the symbol
for a _______ because that's the only component that makes even a little
bit of sense at this position in a circuit like this."

I've got a similar "problem" with a word from chemistry - I remember my
high-school chemistry teacher using a several-syllable word that started
with an "am" sound, which was applied to a class of materials/compounds
(plain old water happens to be one of them) that could be classified as
both acid AND base, depending on the pH of what it was being combined
with - mixed with something strongly acidic, a material to which the
word was applicable would behave as a mild base. Mixed with a strong
base, it would behave as if it were a mild acid. Mixed with material
that was neither acid nor base, it behaved as if it were neither acid
nor base itself. I've searched for literally years to find someone who
can tell me again what that word was, with no luck at all. (Asking the
teacher isn't a viable option, since he managed to find himself
splattered all over several hundred feet of highway and the
grille/hood/windshield of a drunk's pickup not long after I finished his
class)

Concur on all points. Looks like an astrological symbol to me,
but what do I know.

Ouch. Hope you didn't like him very much.

Eh... He was OK. Not the "bestest of the best" I ever encountered, but
reasonably well above the "He's a teacher, therefore he's the enemy"
mark. He also ran the school chess club, introducing me to the joys (and
frustrations...) of the game, routinely beating the pants off me and
most comers for what seemed like ages.



"Amphoteric".



Mark, I think you may have just pulled a rabbit outta yer rump! That
looks suspiciously like the word I've been trying to find for so long.
Lemme go do a lookup and see...

am?pho?ter?ic
adj.

Having the characteristics of both an acid and a base; Capable of
reacting chemically either as an acid or a base.

YES!!!! THAT'S IT!!!! HOORAY!!!!!!

20 years of on again, off again searching FINALLY recovers "the lost
word"!

I've had chemistry majors look look at me like I had three heads when
I've asked. A senior chemist at Dow Chemical in Midland Michigan laughed
at me and said there's no word that fits the definition I gave, only a
hyphenated phrase I've long since forgotten. College chem instructors
scratched their heads and said "idunno". Searches through dictionaries
turned up nothing. (Ever try looking up a word based on its
definition??? OY! Wotta pain!) At times, I even began to wonder if I was
imagining him using it.

You're my hero, Mark! :)

Well, maybe not "hero", but boy is it good to know I wasn't dreaming all
these years!


In case you're interested, I use an old PC based dictionary, The
American Heritage Talking Dictionary, that will search the definitions.
I put in "base and acid and chemical," and "amphoteric" was the only
result. The program seems to be part of Compton's Home Library, it may
still be available. The OED on disk would probably be able to do that as
well. I can get into an online version through my college, but it's a pain.

Uh... Sorry, Rich...

But let's face it... Mine was, unlike yours, an "accurate drawing", so
to speak...

Just a matter of"waving it in front of the right set of eyeballs" to get
the answer.

Yours, on the other hand... Well, as you said yourself, it might not
even be the symbol you're remembering. We're STILL trying to guess
whether what you drew actually has any relationship to the symbol you
think you remember, and if it does, what symbol (of several possibles,
in several different areas of specialization) it could be.

Well, shit. Now you can't look him up and whup him (assuming you

And I wasn't even a chemistry major. Truth be told, the only
reason I remember it is that my pattern-recognition wetware keeps
trying to break it down into components "am" from "ambi" and
something referencing photography, so that'd make it mean "can't
decide whether it's black or white".

You're my hero, Mark! :)

That's quite all right with me; heroism is usually an attribute
awarded posthumously. Especially for doing something right while
screwing up...

IEEE std 315 refers to something that looks like what you drawn as a
partial transformer (para 6.4.20)

Anyway, "IEEE Std 315 - Graphic Symbols for Electrical and Electronics
Diagrams (Including Reference Designation Letters)" would be a good
place to look if you have access to it.

More of the circuit diag. may be helpful.
