No !!

Put it all in the humor section !!

How else to know if the ingot is tungsten coated with gold, without damaging it ????? !!!

By diffusive electromagnetic penetration of the magnetic field, measuring a change in this penetration in depth due to the higher resistivity of tungsten !!

By eddy current control, we can sort material at low frequency by comparison ..... when we have the standards representative alloys in question to be able to distinguish them between them.

Depending on the alloy, its method of production, the Courants de Foucault response is very variable. If it is just a relatively thin plating, if there is a tungsten core embedded in the mass of gold, if it is a tungsten / gold-plated gold sintering .... the combinations are numerous. We can say relatively easily the sample A is different from the sample B near the surface, but to say that this one contains tungsten ..... it is much hotter ........ Especially that after a few mm thickness from the surface, the parameters change and the problem becomes even more difficult.

The problem is that the shade sought (representative) to calibrate is not available on the market .... (except with banksters can be ). Is there a Jeweler in the room to find out how we can get around the problem?

diffusive electromagnetic penetration of the magnetic field

it is the same thing as the eddy currents improved by choosing the frequencies or structure of the magnetic field pulses to regulate the depth of penetration and detect the difference in resistivity between the 2 metals whatever the depth by choosing the frequency, as much lower than this depth is great !!
The shape of the signal after a pulse will clearly reflect the change in resistivity with a small coil against the flat surface and not with everything in a coil for eddy currents with signal which is related to the shape, size and resistivity.
The penetration depth is lengthened by square root of the resistivity ratio, from the square root of a little more than 2 !!

It will be detected at any depth, by adjusting the frequency range, without having a pure ingot in reference.

We can even have 2 coils: a transmitter on one side and another receiver on the other side, which receives a signal only if it is tungsten on more than 80% !! by choosing the right frequency, a few tens of Hertz !!

In fact, it seems that Americans are frightened that the dollar is no longer the global benchmark currency.

1) I think we are unlikely to see clearly given what we know. And since those who know don't know where we're going !!!!

That said, the dollar is no longer the benchmark currency, in any case the only benchmark.

Why do you want China (officially communist of Mao) to accede the debt of Spain and Portugal, if it is not to put the eggs in the same basket (dollar) ???

[Christophe]

Yes, we don't know much.

But that the current Euro crisis is linked to financial "attacks" would not surprise me more than that ... since the USA is also economically weakened at the moment ...



But good considering the little public information on these schemes is speculation on speculation ...

Maybe wikileaks will teach us more ...

If you're talking about Pulsed Eddy Current Control, I'm not a specialist, but the signal you interpret always depends on your sensor and the volume it inspects. No matter how much you increase the depth of penetration inspected by tampering with the pulse and decreasing the frequency, you get a response depending on the volume inspected and the path taken in the direction of penetration, therefore how the metallurgical sample is made (variation in composition) .

Whether you are looking at the phase variation or an FFT you have to correlate with reality at one point or another to say nothing and cut some samples (for spectroscopy control of the alloy shade for example). You have to learn to spot a "signature" of such a Bankstereux alloy by looking in the configuration of the control machine .... and therefore you come back to working with representative standards. We probably only find what we know.

In fact, it seems that Americans are frightened that the dollar is no longer the global benchmark currency. That's why they go out of their way to keep the price of gold low. I heard that it is especially important that an ounce of gold does not exceed 1500 dollars psychological threshold according to specialist beyond which, all people will rush to buy gold with the dollar which drops to zero.

Is gold only quoted and buyable in dollars? If yes ok if not, what I think, I do not understand well the relationship with the quotation of the dollar ...

The relationship with the dollar is simple; The dollar rate is artificial, structurally the true value of the dollar is barely 1/10 of the current value ...
The Chinese who are perfectly aware of it and are "stuffed with dollars" therefore try to get rid of them for more reliable values ​​...

Previously, the same had reinvested their dollars in US treasury bills (the TBonds). When they understood the situation, they sold their TBonds which the federal reserve bought to prevent the system from collapsing.

In return, Uncle Sam turned the money printing press which, by increasing the money supply, should devalue the currency as much ... This is the reason why the indices concerning this money supply have become confidential. ..

By getting rid of their TBonds, the previous investors are again "stuffed with dollars" which they are now getting rid of to acquire safer values ​​(gold, real estate, commodities, arable land ... ).

... yes, and they know that they lose having it .. nevertheless they still have a considerable volume of it ... quite simply because they cannot do otherwise, since it is their biggest market d 'export!

Flytox has not carefully read my text, which is different from what it has practiced, and does not know the skin effect and the radiofrequency penetration in a perfectly defined metal as soon as we know the metal with its resistivity.
http://fr.wikipedia.org/wiki/Effet_de_peau
http://en.wikipedia.org/wiki/Skin_depth
So if on the flat surface of the ingot locally measured over a small area, this penetration depth at different frequencies will be detected a variation in the slope of variation of the penetration depth as a function of the frequency corresponding to the significantly higher resistivity of tungsten. The plane geometry is perfectly defined and therefore there is no unknown and we can calibrate on copper or plane aluminum which have resistivity close to gold, much more than tungsten.
We take a coil much smaller than the ingot.
Finally it is even easier to detect with a small coil on the other side the signal which does not pass if it is gold but which passes much more if it is tungsten, with an amplification by the decay exponential with the distance of the oscillating magnetic field. By making the measurement on a copper plate of the thickness of the ingot we calibrate and correcting with the resistivity ratio between fairly close copper and gold, we know what we have to detect. We can study according to the frequency.
If we detect much more, it's tungsten.

Finally, in a similar way instead of electromagnetic waves with known penetration,, we can send ultrasound into the ingot and measure their propagation, their transmission and reflection and detect the surface of the tungsten which returns these waves with delay which allows to know the thickness of gold. You can have a transmitter and an ultrasound detector on each side ingot. It is actually also easy with ultrasound.

We can even study the ingot's resonance modes by tapping on it, like on a bell, which will be very different, like a bell, badly made or cracked. !!

With an electromagnetic wave the principle is quite similar except that its penetration is diffusive and that the analysis is more complex.

We agree :
China has no interest in a crisis in the USA and Europe, because so serious, real, fall in our purchases of Chinese goods and brutal unemployment in China and risk of revolution or riots in China as in Tunisia and Egypt, which are starting strongly, with the poor exasperated.
So supporting dangerous debts for our economy and our purchasing capacity !! and which moreover will be reimbursed better than the long-term dollars, given the German guarantee.
The dollars of China have value only that of our economy.

which increases their prices, like food, land, oil, etc. in connection with the improvement in the standard of living of some Chinese.
