caduceus coil building and testing

[stivep]

 Lithuania experiment original yoke from Russian Tv Rubin  experiment from 2011

Here is the catch or inconsistency:
SWR (Standing Wave ratio meter) SWR-1180P - Radio, 1.7-150 MHz,   shown  on the pictures  at the bottom of this comment
operates  and frequency region inconsistent with  conditions of the experiment for one of generators.
https://www.elfa.se/en/radio-150-mhz-team-swr-1180p/p/11075761
- the frequency set on one generator was ~50Hz and  SWR operates from 1.7MHz up to 150MHz
- the second Generator was suppose to  be sent at around 220kHz but we used 1.2-1.8 MHz.
  So this SWR couldn't operate at 220kHz.
I'm not sure now what was  the exact frequency  of the test but I'm sure I have it on hundreds of videos I have on that old  Hard Drive

But Guintas  used it anyway .

 Because copper foil  is at 90  degrees to the  winding in one half of the yoke than we suspected NMR taking place
in process of transmutation of the ferrite , when energy was released , and  that energy  was than converted to energy powering the lightbulb
Eventually we ruined  quite few ferrites, due to vibration. The high  acoustical  frequency sound was heard .
So the two generators 1W each was only   acting like a key:

In classical physics if we use analogy:We can compare it to valve on the  pipe with water  that is connected to the river.
To open the valve there is  very little energy needed.
And that role was carrying on set of two generators
Each one was  around 1W if i remember it  properly.
one  of them was delivering around 50Hz the other was at the frequency of resonance of the assembly.
However Arunas T-1000 tend to call  it ferroresonance frequency- I'm not sure of how much it is correct  descriptor.

I'm quite precise  describing  physical phenomena taking place but we didn't have tools to assign  them properly.
We have heard the noise,  felt the vibration of the ferrite core and experienced  severe side effects.
Definitely we got   at output   consequently  600W dissipated at load and than 1kW dissipated at load .

Summary so far:
So we have two  caduceus coil assembly  in Lithuania experiment.
Both  do the same job.
- one is winded  the way that  it  not allow  to disassemble it or change alignment  of the components
but you can still place inside of it ferrite as deep as you need it.

- second one is made the way that it allows to  change the  pickup coil for another one with different 
  number of winds or  change caduceus  for  winded  with different geometry and number of cross points
  that was one part of experiment.

The second part of experiment was :  experiment with yoke  where   pickup coil  was made out of
two independent windings winded on one half of the yoke   one on the top of the other .
   picture :    https://overunity.com/19358/caduceus-coil-building-and-testing/dlattach/attach/189637/

Than two ends of  each individual winding were connected together  leaving two reminding ends  unconnected yet acting as an  output.
that  by itself made   that half of the  yoke similar to pickup coil   that was used for the first  part of the test  with caduceus.
That means that winding  on this particular half of the  yoke  was alike the winding   on the pickup coil( outer coil)  on caduceus.

applies to  experiment with  yoke with some minor changes.

The main difference between:
-the two is that Yoke  had two half parts.
    picture :    https://overunity.com/19358/caduceus-coil-building-and-testing/dlattach/attach/189633/

-the ferrite ring was  not made from two halves

There is another factor  important .
The yoke  halves  were  placed together but  allows to introduce  small gap between the halves from one side
or both sides.
-sometime that gap was regulated by placing in between  one or few pieces of  paper. to keep the space in controlled thickness.
similar technique was used commercially in flyback transformers in every TV using CRT tube called also cathode ray tube.

https://www.electronicdesign.com/markets/energy/article/21761319/mind-the-gap-and-improve-your-lowpower-flyback-transformer-design
The flyback transformer is very different from a signal transformer, and not making the distinction can lead to poor performance.
Actually, the flyback transformer is a coupled inductor and not a transformer in the true sense.

In the signal transformer, current flows in the primary and secondary windings at the same time, inversely proportional to the turns ratio of the windings.
In a flyback transformer, current flow is restricted to one winding at a time.

often associated with word "kinescope" in Eastern Europe  however history of that word was little different.
