Donald Smith Devices too good to be true

[Farmhand]

i would love anyones thoughts on Tesla's patents 336,961 and 336,962

http://www.tuks.nl/pdf/Reference_Mat...sla_patent.pdf

http://www.keelynet.com/tesla/00336962.pdf

the parts explaining the self-excitation using auxiliary brush and coil in iron case,
the regulation using the automatic means,
the enhanced effects of the coil with reversed direction windings,
the outer ends of L2 being pos and neg rather than neg at center tap
the comparison between L1 Don used and the armature Tesla used


Understanding of these i believe to critical, as they are most likely the origin of our discussion... and what Don openly based his experiments on

Those patents appear to be for ways and means to regulate the output of
dynamo electric machines. The automatic brush position adjusters are
solenoids designed to move the brushes to a position relative to the strength
of the currents through the solenoid coils. These regulators either shunt part
of the field current or restrict the field current in the machine by other means
such as counter or cancelling emf's in order to regulate the output from the
armature, the stronger the excitement of the field magnets the more power is
produced from the armature or generating element. By regulating the field
currents relative to the load the machine is more practical.

Much like the regulator in a car alternator regulates the current through the
rotating field winding to regulate the output of the generating stator coils.

I showed in this experiment the regulating/magnetizing DC current can be utilized.

Alternator Test - YouTube

At about 2:20 minutes I switch out the regulator so that the 21 Watt bulb is
the only load regulating the magnetizing coil current. The actual alternator
output was to the big battery. The bulb regulated the charge current down to
about 4 amps from about 8 amps by restricting the current through the
magnetizing coil. Usually the regulation is done with a transistor and/or
resistors to restrict the magnetizing current..

great input Farmhand, and great alternator test!

No Probs, I forgot to mention, the "self exciting" part simply means that the
current that actuates the solenoids to adjust the brushes comes from the
machine and is automatic insomuch as the strength and timing are a result of
the effect of the load applied. ( I think at least some are ), it's just a matter
of engineering to get the desired effects automatically, that is one reason
why counter emf or (back emf) are a gift It is what makes most things automatic.
Like the current through a power transformer primary when the secondary is
loaded (exactly the right amount is allowed) if the transformer is designed correctly.

Car alternators can be self exciting now and are very similar to some of
Tesla's HF alternator designs particularly the saw tooth field core design used
in alternators (the claw). That's Tesla's finding as well.

This is also similar to the self excitement of the field magnets (magnetizing coils)
in the Unipolar dynamo. Which is described as being capable of "self excitement".
That just means the field magnets are excited by currents produced by the
spinning of the discs. The discs still need to be spun by mechanical means,
wind, water, motor ect.

The interesting things about this machine, is that if the field magnets are made
to cover the entire surface of the discs, there is no armature reaction.No Lenz.
But only if weakly energized. Also with the twin discs the currents can be
taken from the shaft of both discs, and there is no need to counter rotate the discs,
it just needs the polarity of the field magnets reversed on one disc as to the
other. Always low voltage high current output though. I would love to build
one and I will, just as it is drawn with the twin discs and electromagnets for
the field magnets.

Again, the facility with which such a machine may be made to
excite itself is striking, but this may be due besides to the absence
of armature reaction to the perfect smoothness of the current
and non-existence of self-induction.

ok sweet, so then do you think that the L1 coil replacing the armature is a good substitute?
and what about the center-tap neg vs outer ends pos/neg?
Tesla wrote the ends were pos and neg, could the "auxiliary" tap be any other kind of connection?

And Dynatron uses that RF choke off center tap, could that be the same as the excited solenoid in Tesla'a patent connected to "aux brush C" ?

im just trying to make the similarities and mentally convert the armature to L1 coil
the 3rd config in 336,961 is so Kapanadze, with the main coil, then the other wound half then back half, so interesting, and Don mentioned it enhances current by cancelling the v from the opposing direction, anyway, experiments continue

Glad,see you again Sir,your analytical skills and experience is a blessing to us.

Keep it up.

Best regards,

To Clarence

Hello Level & ALL,

electronic NSTs useless for Don Smith type builds. this manufactrer I guess finally got the word that there was a definite market for the old original style NST design and started includeing them in his listings. this should help you in your search to stay with the specifics that don mentioned for you builds.

LOL - If I may be of info service to anyone in any manner just let me know, best regards as always, mike, onward!

Thanks for this Clarence!

Farmhand vid

hey Farmhand can you explain a little more what your reciever is? you said it was picked up by your solar controler? but it was recieving radio transmission?

Sensitive receiver - YouTube

ive been really looking at Crytal / transistor radio circuits, except tuning obviously to the driver freq, and making it a high power radio reciever with IGBTs or something, if its possible

anyway very cool vid!

...oh ok i think i get it it was noise in the signal from the controler

ELECTROSTATIC RADIO RECEIVER

A publication by the Center for Academic Publication in Tokyo, Japan, Magnetospheric Plasma Physics, edited by Atsuhiro Nishida, brings together some prominent world physicists for a very clear picture of the Earth energy structure, along with some rather complex mathematics for those wishing to follow their modeling.

The conducting ionosphere can affect the instability by short circuiting the electrostatic part of the Earth electric field, thus requiring less energy to release charge from the upper layers. These auroral arcs result in an acceleration process called ring currents, processing along the magnetic field lines that connect the magneto tail with the ionosphere. This is the primary supply of energy for the aurora, setting up an oscillating field aligned acceleration of aurora particles; therefore forming the aurora arcs. This process releases a radiation called auroral Kilometric radiation (AKR) from 50 to 500 KHz. These arcs are generated by convection currents formed in the plasma pause of the magneto tail. These arcs curve toward the Earth on the night side and enter or create the aurora field at around 68 degrees latitude between 22 and 24 hours local time. The Auroral Kilometric Radiation (AKR) has a frequency spectrum of from 30 to 500 KHz, with a peak power at around 200 KHz. The total power is about 1000 Megawatts, and the radiation is right-handed polarized. It originates at a low altitude, less than three Earth radii, with a radiation power of about one per cent of the energy dissipation of the auroral particles.

It appears that the electrostatic waves stimulate the ionosphere, thus allowing the influx of the powerful AKR energies. Very strong electrostatic waves have been monitored, between 17.8 and 100 KHz. with the greatest amplitude at around 31.1 KHz. Some of these same effects and frequencies have been observed by the Voyager 2 flyby of Jupiter and Saturn, within their magnetospheres.

wow chipdip's channel is golden

they are very professional and conventional,

funny thing, i believe he said it could power itself as well LOL

Very Cool, great info!

im planning on the Ion Valve next!!

I tested this Transverter/Rotoverter config with a quadrature demodulator this weekend.
This kind of config is very common in FM/PSK radio demodulators.

The rectifier bridge demodulates the phaseshift current to a DC-voltage in the cap.

It gives back the 7.5v 2.51A into the capacitor and if Rload is a dead short the current draw is still the same 1.38A

It works extremly well

[janost]

It didnt work with a current transformer because the phase current is almost a squarewave and not a sine.

The circuit works as a resonant charger.

Resonant charging

[janost]

It can also be done this way with 2 diodes and 2 caps.

The reason for one setup on each side is to keep the AC load symmetric.

[janost]

I calculated the phaseshift to about 23deg.
That would make my LC-combo frequency 43.5Hz

About 6.5Hz of from 50Hz.

What this means is that you can keep the tank-circuit on the secondary side untouched.
And it feeds back the energy in it back to the primary side.

I bet this would work even better with a ferrite wound transformer and KHz frequency.

[janost]

If you still don't get it I'll make a really simple example:

If Rload is heating wire, you force the current to pass it twice on each cycle.

That is COP 2 heating

If the tank was resonant on the 2nd harmonic it would cycle 4times on each input cycle.

Most simple is feeding it with a squarewave which contains a strong 3rd harmonic.
That results in 3 cycles on each edge of the input.
