Si-diodes in Second World War radar & Communication equipment

ronwer · 2008-04-12T15:51:10+00:00

Hi!I am doing a study into the early use of silicon diodes in radar andcommunication equipment during the Second World War.What I would be interested in is as follows:-type numbers of the diodes-name/type number of radar/communication equipment-technical infor on those systems-info on producers-pictures of actual diodes, also "in" the circuits-anecdotal stories about the actual use-anything else!The information will be used for an on-going study project related topractical application of minerals (i.e. quartz) in industry and technology.So, since this is an aspect of a broader study, other quartz-related info wouldbe most appreciated, especially about early use of piezoelectricquartz crystals in electronic equipment.If you'd prefer, answering off-list is possible:Thanks for ANY help!RonaldNorway

Paul -

I know what was on the B-36 and B-52 - Radar and radio.

Tube tube and tube. I trained the F-111 designers for the first solid state plane. It had a lot of firsts - swing wing... Fast and slow.

I used to have tens of thousands of tubes. Mil spec. They would use them for 100 hours and replace them.

Bikini - used to live hundreds of miles from it - wasn't the first at all - nor was those in Japan.

The bomb was tested in the states long before anywhere else. Knowledge was gained on a number of fronts.

But theory and Science knows more than you. Much more was known long before as the bomb was known before they figured how to make one.

Mart> Mart>> I know for a fact the B36 and 52 were tube models.

About 5'6". I met John at one of those trade shows in LA, and got about a half-dozen of his refrigerator magnet logo thingies. Apparently I voided the warranty when I stuck them to my file cabinet. ;-)

He's adorable, like a friendly leprechaun. :-)

His face wouldn't frighten children the way yours and mine do. ;-D

Hope This Helps! Rich

PKB, methinks. What you should try sometime is growing up and owning up to a mistake like a man instead of always starting a childish row to divert attention away from the fact that you made a mistake. JF

Around Christmas time, in the grocery store, little kids point at me and say, "Ho! Ho! Ho!" ;-)

And I've never seen a kid yet that I couldn't get to smile.

Which mistake are you referring to?

Do you keep a scrapbook of my mistakes? I'm flattered.

I\'m not talking about any particular mistake, I\'m talking about all the silly little diversions and the dance you do when you\'re confronted with the _fact_ that you made a mistake and you don\'t want to own up to it.

Certainly not I. I\'m being sarcastically critical of _you_ by implying that, since one is known by the company one keeps, your admitted preference for _totally_ female "peers" kind of puts you in that camp. JF

You are really losing it. Back off, count to ten, press reset, and try to start thinking again.

I genuinely like and enormously respect women, and would rather, all other things being equal, spend time with women than with men. But I've never met a female circuit designer (lots of programmers, scientists, managers, just no real circuit designers) so I do that with guys.

So how does a preference for women friends put me "in the camp" of people who debase women?

A lot of guys really don't like women. They want them, need them, but don't like them. How do you rate in that respect? I've noticed that this group seems to pile onto any woman who dares to post here, and you tend to be part of the gang.

5'7.5". Maybe hard to estimate from your extreme elevation.

I met John at one of those trade shows in LA, and got about

Your file cabinet has a warranty?

Kids and dogs and women seem to like me. I work at appearing innocuous, to make a neutral first impression until I size up a situation. That seems to work in most business situations.

By casting aspersions on males and then equating those aspersions to what you consider to be female "characteristics", you cast aspersions on women just for being women. Can\'t you see that? Probably not, since the "knowledge" you say you share is, more often than not, banal and "Hey, look at me! Ain\'t I great???"

Geez, I hope you don't use that sort of logic when you design your 555 circuits.

I prefer broccoli to brussels sprouts, ice cream to tapioca, picoseconds to milliseconds, women to men. Where are "aspersions" in any of that? If I have maligned any food products or time units, it wasn't intentional.

You didn't answer my question about if you actually like women. If you prefer men, go for it.

Boy, you don't remember stuff too good, do you? ;-) I took a picture of them stuck to my file cabinet, posted it on a.b.s.e, and you said that I'd voided the warranty. I asked, "What, by not cutting them in two?" because you had mentioned being able to separate the saying from the logo and address & stuff. You said, with much indignation, "They're _REFRIGERATOR_ magnets!" (I don't remember the exact level of emphasis, but it _was_ emphasized! ;-) )

I can't quote chapter and verse, because google doesn't archive alt., which I don't get any more anyway. )-;
