Here's some pictures related to the EC52 core we all talked about.There will be two pages from the International report and a picture of the vic coil that is in the control box for the variable plate demo cell

Awesome!

I think that says 05 / 23/ 80 ... May 23rd 1980, nice to know!

Who might have a set-up that they could readily build and try this coil? I would love to see it in action!

Update! I have been testing with the 12V stator and the results are pretty close to my predictions but, I ran into some weird stuff. What happens is, I run the cell as usual and the pressure seems to stop building even though the bubbles do not dissipate like when it's turned off. Well, I'm thinking this was a leak or something like that. When I turn it back on, the gas pressure rises as usual for a brief period of time and then stops again. Again the cell visually does not change. When the cell is turned off, the bubbles dissipate rather quickly. Could this be why Stan used gating?

I can't thank all of you enough, especially Dynodon for all the information. I will still be testing the tubular setup for some time but, I am now beginning my next project building the other demo cell setup with the variable plate gap. I have almost all of the materials in house, so it won't take as long to get it built. I hope. I still have to build the choked stator coils yet, so I have a bit on my table. Not to mention, the Stiffler circuits I bought that are still in the box. I have too many toys.

Thanks again everyone! Happy Holidays!

Dynodon,

Do the numbers 56 and 62 indicate the number of turns of each individual choke?

No those numbers represent the reference numbers in the tech brief.Look at tech brief 426 figure 7-1,you'll see the nubers there.

Got it Dynodon.  Thanks.  That would be an example of what I refer to as anti-parallel configuration of the resonant charging chokes if they were wound bifilar on one core.

"Others are wound so that the current flows in opposite directions. The magnetic field created by one winding is therefore equal and opposite to that created by the other, resulting in a net magnetic field of zero (i.e., neutralizing any negative effects in the coil). In electrical terms, this means that the self-inductance of the coil is zero.

The bifilar coil (more often called the bifilar winding) is used in modern electrical engineering as a means of constructing wire-wound resistors with negligible parasitic self-inductance."


"An early example of the bifilar coil can be seen in Nikola Tesla's United States patent 512,340 of 1894. Tesla explains that in some applications (which he does not specify) the self-inductance of a conventional coil is undesired and has to be neutralised by adding external capacitors. The bifilar coil in this configuration has increased self-capacitance, thereby saving the cost of the capacitors. It is notable that this is not the kind of bifilar winding used in non-inductive wirewound resistors where the windings are wired anti-series to null out self-inductance."

There is still inductance in the wire just not self inductance. We can also still induce voltage into the wire by a changing magnetic field from the core. The magnetic field is produced from flux sort of leaking out the sides of the coil where the wire is not face to face. The magnetic field is not canceled as it is more confined to a smaller area.

Hi Bubz,

That was my understanding and why it was drawn that way to restrict amp flow and allow voltage to take over.  Stan's words not mine.  My coils get hot either way less so with distilled water.  I added a photo above.  toroid coil 100 turns bifilar 200 turns total 20 gauge silver coated teflon wire.  Looking at it I think it's configured in anti-parallel mode similar to how Lawton would wire it current complementing and the coil would buzz at one frequency that I could tell.
