@All
Just to add, I am attaching a pdf book. From page 171 there are a few pages referring to something similar and drawings seem alike for those days.
@Grumage
Good to see you are testing with a transformer. I think with a standard core or toroid multi-layered transformer that was built to be run by AC, maybe just use a Variac and if you can plug it into a wattmeter and run that single primary at maybe 10-20 volts max to see how it will respond. But no higher to not risk burning out your coils.
I am putting up a photo taken many years ago of my three builds. The problem is these builds are more following @brnbrades' lead at OU back then. Cook says in his patent that he prefers using the same wire for both coils and that any mix could be used to get a specific desired effect, so given my builds are tightly wound thin wire first and thick wire out, I think the build is wrong if I base it on Spin Conveyance. My thin wires are wound so tight together and this will create an incredible amount of internal cancellation that would work against the Cook effect that requires as non hindered ability to shuffle the potentials with the least possibility of cancellation.
But before I go into this patent any further I needed to analyze what Cook actually says in the patent.
Cook says his wires can be insulated with silk, shelac or parafine. They did not have plastic coating then like we do, but I am sure the wire they used then had insulation that was thicker then what we have today and hence, this may be good when winding coils so there is some more space between turns, which in the atomic scale is immense but for us it may seem frivolous. So I think my builds may be good but only once a simpler version is better understood to show the basic effect of gain with the right peripherals that he calls circuit D.
So I went here......
http://deepfriedneon.com/tesla_f_calchelix.html and using this coil wind calculator I set it up as follows;
For turns spacing I gave it half the 16 AWG wire diameter so the ideal wire insulation would add 1/4 the wire diameter times 2 when two turn meet side by side so half the wire diameter is used as the spacing.
Example 1
Units: Inches
Diameter (D): 2
Number of turns (N): 1000
Wire Diameter (W): .051 or 16 awg
Turn spacing (S): .0255
The results were as follows;
Height (H): 76.5 inches or 6.375 feet of core
Length of wire: 6283 inches or 524 feet of wire
Inductance (L): 1292 uH
Self Capacitance: 22.5 pF
Example 2
Units: Inches
Diameter (D): 3
Number of turns (N): 650
Wire Diameter (W): .051 or 16 awg
Turn spacing (S): .0255
The results were as follows;
Height (H): 50 inches or 4 feet of core
Length of wire: 6126 inches or 510 feet of wire
Inductance (L): 1861uH
Self Capacitance: 15.3 pF
Example 3
Units: Inches
Diameter (D): 4
Number of turns (N): 500
Wire Diameter (W): .051 or 16 awg
Turn spacing (S): .0255
The results were as follows;
Height (H): 38 inches or 3.1 feet of core
Length of wire: 6283 inches or 523 feet of wire
Inductance (L): 2497 uH
Self Capacitance: 12.6 pF
When we analyze the above results and when Cook says the core can be 2, 3 or even 6 feet long and the core diameter can be 2, 3 or more inches (I also used 4 inches), you start to see the relevance of those numbers and he then says the coils are using 500 to 1000 feet of wire. I matched the turns to arrive near the 500 foot mark to see the core lengths and they all fit in his numbers. If you double these for 1000 feet or wire, only the 2 inch core would be 8 feet long so that's a little over his 6 feet but still in a realistic and fairly accurate depiction that he is giving us on those build specs, if the wire insulation is in fact thicker then magwire we have today, the patent seems OK.
I tried looking for a web site that might have antique copper wire samples but have not found anything yet.
But winding 16 awg wire on a 2, 3 or 4 inch diameter iron core just seems crazy, even suicidal (watch your toes). How much would those coils weigh? How can such little wire have any serious impact on such a huge core? This is the part that I don't get. Why so much iron mass? Before a 16 awg wire could develop any serious saturation of those cores to actually render them to any level to achieve any "magnetic" action.
Then what I don't get is if this is real and so simple, it would achieve a Category 1 as being the least complex on the OU complexity scale (my way of grading worldwide device replication potential and appeal), then he could have sold millions of these all over the world so WTH happened?
I think if there is any real truth to this patent, Mr. Cook at least got his numbers right so the information does hold up in that regard. As for the actual function, I'd then say use his favorite wire of 16 AWG for both coils, for now until the effect is understood. From there one could make deviations with 30 awg primary but as a best shot for success, I'd stick to same wire primary and secondary, so the difference will only be one coil near the core and other further off the core.
The effect on my small wire rod core device which has about 3/8" cores about 1 foot long and for which I can also post build specs etc., is that the looping effect is indeed there but most probably not enough core mass to make it grow, and also my primary wires (1 layer) are very thin tightly wound so there is a limited amount of looping that can occur and there is great potential for inter wind cancellation. When pulsing the outer wound coil #5 that I added, the impress goes to the secondary right under it and the primary does not see it as I had suspected. So the impress goes from coil #5 to the secondary and from there it is conveyed through the other coils. I will test the primary to secondary impress potential and let you know.
It is funny though. Looking at this after so many years and seeing the results with what I know today takes away many of the questions marks. At the time, @Brnbrade was not that forthcoming with his directive so guys were more or less working this blindly (nothing new there hey), but had I known what I know today, the build would not have been the same and I would have made sure there was some spacing between the primary turns and we would have realized the requirement for a coil #3 or #5. Why we did not see that then is just puzzling. We were really impressionable then just getting out of SM's entanglements so we were the perfect hungry sheep, ready to follow anyone with some semblance of OU on the plate. Hmmmmmmm, seems like nothing has changed on that front. hahahahahahaha
