Surplus electricity

Er, because you disputed the claim. And got it wrong.

I didn't actually dispute the claim - I just said that I hadn't heard that mixed zinc and aluminium metalisation was ever used.

After I'd dug into the pile of links that John Larkin had posted - apparently without bothering to read any of them - I found one example of mixed use - when a thin layer of aluminium metalisation was used to provide better substrate for a slightly thicker layer of zinc.

It's not exactly mixed use - all the aluminium substrate does is provide a firmer foundation for the zinc layer that does all the work.

I didn't "get it wrong" no matter how much you would like to see it that way, but rather provoked an eventually more informative answer, not that John Larkin contributed all that he might have done to the process.

Of course not Bill. It is clear that you can't be wrong. Even when you are.

I certainly didn't produce as good a response as John May has, much as I would have liked to, and to that extent I have got it wrong. You haven't contributed anything useful at all. I suspect the pecking order goes John May, me, John Larkin and you, with your "contribution" being entirely negative. You have done better in the past, but this wasn't one of your merely mediocre days.

Thank you Headmaster. I'll try to do better next time.

You clearly have a desperate need to compare yourself with others Bill. And a desperate need to be up there with those whom you perceive to be up there. And a desperate need for respect, rather than criticism (direct or implied), from those whom you perceive to be up there ahead of you. And a desperate need to be disrespectful to those whom you perceive to be not as up there as you are.

As I see it, two interesting things drop out of this.

One is that those who really are up there don't seem to have these needs, but I don't speak for them.

The other is that you expect respect, not criticism, from those whom you perceive to be up there ahead of you. And your head nearly explodes if they do make a post which implies that you might have been wrong. But you show no respect to those whom you perceive to be not as up there as you are.

Here's a further contribution from myself.

I've no idea who got what from who or what its origin was but if I wanted to know anything about capacitors I'd start here:

I found that information while looking for information in addition to the information JM posted. To find it I had to think outside the Google box.

You have been told that you are stupid. Say three Hail Billies and confess your sins and try to be better in the future.

That's kind of weird. I don't expect "respect" from anybody. Well-founded criticism is useful, and I do pay attention to it.

I don't like being told that I was wrong when I what I posted was less wrong than the post I was responding too, and I'm even less enthusiastic about people who do it without posting a shred of justification for the claim.

You should know where it came from Company Name: Nantong Huayu Electronic Co., Ltd. founded in 1987 in China

It pretty much duplicates the information in the link that John May posted, and was presumably derived from the same source. I'd suspect Mullard from the style - their application data was never as technical as the stuff that came from Siemens, and less well grounded in the fundamental physics.

What's missing is any indication that the metalisation goes down in isolated islands which have to be bridged to adjacent islands by at least two bridges that have to be at least a single atom thick - since the metalisation seems to go down as multi-atom crystalites the bridges aren't likely to be single atoms. Expressing that in an easily comprehensible form for people who don't like thinking about single atoms isn't all that easy.

Edward Rawde isn't stupid. He's not clever, but he does come up with good ideas from time to time. The thread on very low distortion sine wave oscillators come to mind - John May did improve on his improvement by chopping out several transistors, and I managed to improve a little on John May's improved circuit by plugging in an extra transistor and going for a bit more bias current. It was very much a joint effort, though Edward doesn't seem to see it that way.

He certainly isn't any kind of sinner, if less collegial than he might be. He does share that defect with you.

LOL the ciruit was almost entirely due to JM, particularly the oscillator. I had already got as far as polyphase but JM's oscillator and polyphase rectifier is much better than the circuit I arrived at myself.

I can assure you that I'm able to copy/paste from a web site Bill. You missed the point, which was that I was curious how the information JM posted can also be found word for word (less the page, figure and table numbers) on a Chinese web site. The spelling of aluminium is also interesting.

But that isn't what you posted. and you clearly hadn't read the whole of my post when you posted that comment. I made the same point about the information matching John May's document, and speculated that it orginaly came from Mullard, a British firm, if eventually taken over by Philips, who would have used the European spelling of alumimium, rather than the American "aluminum".

LOL How do you think I determined that the information JM posted matched that web site Bill?

Who cares? "Determined " is a pretentious choice of word. There are lots of ways you could have done it, and you haven't specified which one you chose. I thought that the content pretty much matched the content of John May's document, but I didn't test it explicitly, and certainly didn't "determine" anything.

Oh it certainly matches, but whether or not it has anything to do with Philips is unknown. I don't know exactly when Philips stopped making capacitors but it was a long time ago and you might find it hard to get anything new which wasn't made in China these days.

Philips application notes tend to be a bit better than that. They may have called on their NatLab staff.

China is in the business of making everything and exporting it everywhere. Film capacitors use a variety of plastic films - poly propylene seems to be the most popular, and that wasn't developed until
