Tesla's "COIL FOR ELECTRO-MAGNETS".

[Farmhand]

As Far as the "COIL FOR ELECRO-MAGNETS" patent goes, the claims are at the end of the patent, they are correct and truthful. Tesla explains himself well in the patent. I don't see any need for any further argument, if people can use the coil winding advantageously in any way they should feel free to say so if they have evidence of it or it is obvious to others.

All coils that produce a magnetic field from an electric current input are technically electro-magnets, I think it is explained by Tesla he means any coil and the effect of the cancellation of the "effects" of the self induction can be secured in any coil if the right conditions are met. To me it seems plain and simple.

Milehigh, if I may ask, what part of the patent is it that you have a problem with ? If you have a problem with part of the patent then please say so. But I have to say I'm not interested if it has not to do with if the patent is correct or not. If you are not disputing the patent claims then I have no argument with you. I see no need for argument on the patent itself.

Deepcut promised to try the diametric neo magnet as SBC core to test for AUL, and shortly after, he vanished suddenly and completely from the Free Energy Forum for superficial reasons.. The MIB may have stopped by and shown him snapshots of his children in their school yard. This subject makes alot of people very uncomfortable. Judging from that and the general level of hysteria over my second "tectonic" paper clip claim, it makes me wonder about the seriousness of the MIB threat in U.K., and possible infiltration into this thread by imposters planted to help spread misinformation and falsehood! .

Here's more definative proof in support of my claim:

Have a look at this video of an "Impulse Charged Multifilar Pancake Magnetizer Coil": from 3zdayz:

This is what Tesla's bifilar pancake coil was patented to do! A ferrite slug would PM in the core jolt. Take note of the size of the spark. No single wire coil could match that gap width.

Multifilar pancake inductances, from 3zdayz:

http://www.youtube.com/watch?v=AQi-5xSeP_U

Published on Mar 30, 2013A bi-filar is definatly more inductance than a single.  As a motivator (generating a magnetic field) it is a more noticable field.

A quad filar has 50% more inductance than a bifilar; a bi filar has 100% more inductance than a single, or than the sum of the parts.

The flatter the coil, the more notable the effect, chaos, or overlapped windings reduces the inductance.

56+58 = 114; actual 224
13+14 = 26; actual 41

quadfilar 0.026 + 0.026 + 0.26 + 0.026 = 0.104 ; actual 286

0.26 + 0.26 - actual 0.083
0.26 + 0.26 + 0.26 - actual 0.171
and the 4th in series - actual 0.295

so the result is more than 10x a single winding for 4 windings.

the result is 4x a single winding for 2 windings.

So by that I guess it would be 25x a single winding for a hex-filar coil...

but there must be diminishing returns...

The flatest pancake coil is 33 turns each (total 66).  So the quad filar would be like 16 turns.

So if I made like a 32-filar coil with 2 turns, and put them all together?... but then isn't it at some point really getting back to mono-filar coil with an offset of 1?

----
The wider, quad-filar coil (usually to upper left) is fairly flat.  When I took it out of its form it lost integrety a bit.
The narrow-er quad-filar coil is actually somewhat overlapped, so it's 2x2 winding basically.

Since i started this thread I'm going to take the liberty to go a bit further off topic to illustrate a point.

I hear all to often the claim that the Tesla transmitters for the transmission of signals and such without wires, must use spark gaps or capacitor discharges ect, but that is untrue, and I have words from Tesla to show he never insisted that was the only way.

In this patent linked below. Tesla clearly says that an alternator can be used to energize the primary. The words are crystal clear. As far as I know alternators produce continuous sine waves.

http://www.google.com/patents?id=oSo_AAAAEBAJ&printsec=abstract&zoom=4#v=onepage&q&f=false

Page 2 line 62 to 69

This source is usually a condenser charged to a high potential and discharged in rapid succession through the primary as in a type of transformer invented by me and not well known but when it is desired to produce stationary waves of great lengths an alternating dynamo of suitable construction may be used to energize the primary.

So there is another misconception, Tesla did say an appropriate alternating dynamo can be used, as he did use many times.

As I see it it is our responsibility to point out when people say otherwise and contradict Tesla while purporting to support his work and legacy.

The patent linked in this post describes "The Art Of Transmitting Electrical Energy Through The Natural Mediums". And If any patents are to be questioned I think this is the one to look at. If the claims in this patent are shown be incorrect or false, then that would mean something.

So anyone want to quote from the patent and say it isn't so ?

Farmhand:

I have no issues with the patent.  My real question is what can you do with it?  If there are no real applications then it's just a curiosity.
