I am new to this forum and have read the posts dated prior to October 2014. You people have really put forth some good stuff. So far, I have not seen a simple, low power circuit that provides 90 degree out of phase excitations for the Figuera 1908 patent. Therefore, I present the following for your consideration. I hope you find it useful.

Attached is a drawing of a circuit whose inputs connect to the count pulse outputs of the CD4017 circuit provided by Patrick Kelly. Each output pulse simultaneously drives the bases of two NPN 2N222 transistors. Each base draws 2.4 ma. The counter outputs are rated for 10 ma, so they are not overloaded. There are sixteen transistors in all. The transistors sequentially ground connecting points in two different strings of series resistors in the adjustment circuits of two LM317T adjustable voltage regulators to provide two quasi-sinusoidal outputs that are ninety degrees out of phase.

Each output is capable of supplying 1.7 Amps. The LM317Ts can handle up to 37 volts DC. If greater current is required, the outputs can be used to provide input signals to emitter followers or other high power devices such as DC drives - assuming the acceleration circuits can be adjusted to permit the rapid response required for this circuit.

The resistors are selected to simulate the equivalent of a 90 degree segment of a sine wave. The values progress from small to large in both strings. The sequence of grounding in one string progresses from small to large, and the grounding sequence in the other string progresses from large to small, thus producing outputs that are 90 degrees out of phase.

If you check the application notes of the LM317T, you will find that they suggest a different circuit for digital output selection. I chose not to use it because the required watt ratings of the small resistors were larger then those of the circuit I used. This is shown in the attached spreadsheet.

I have not yet built the complete circuit. I have built half of the circuit powered by 12 VDC to verify that the LM317T can respond fast enough. It does. However, I do not yet have a completely satisfactory working circuit. The attached oscilloscope picture of one of the waveforms shows that there is a problem in one of the counter circuits that causes some of the segments not to appear. I have not yet fixed this, but suspect that a couple of diodes are malfunctioning as I have seen similar problems while getting this device working.

I would appreciate any suggestions for improvements to this circuit.

Thank you Chris Sykes, i admire your work and appreciate your in put. I am curious as to why you wanted me to download this as i have an earlier one that i have been studying that is the information that was available to Figueras. i have downloaded it and have been reading it but i must admit it is the same info that is in the earlier version.
is their any specific section that you think i need to study.??... if there is please let me know
i have also been studying all other patents and have come to the conclusion that all are right about the coil orientation. i have also possibly uncovered another clue to his device and it have to do with Hanon's delay effect.
in most of the patents the cores that were drawn were very long in proportion to the coils and with this set up a delay effect would take place.
also i would like to bring up that the secondary cut away in the first pic. notice that the primary is cut away also. could this be that the primary core was hollow to allow for an adjustment of some kind as in to get the exact delay effect Hanon was referring.  if you look at the other patents you will see that all of them have a long secondary core except two that have no core drawn.
first pic is my point
other pics are of long cores.

the last line on the right is suppose to be 'induced' not enduced and Sorry for the stupid large pic !

Ps. my materials i ordered have still not come in and i am really P O ed. so i haven't been able to do any test.

PRINCIPLE OF THE INVENTION
Watching closely what happens in a Dynamo in motion, is that the turns of the induced circuit approaches and moves away from the magnetic centers of the inductor magnet or electromagnets, and those turns, while spinning, go through sections of the magnetic field of different power, because, while this has its maximum attraction in the center of the core of each electromagnet, this action will weaken as the induced is separated from the center of the electromagnet, to increase again, when the induced is approaching the center of another electromagnet with opposite sign to the first one.

Ref: PATENT by CLEMENTE FIGUERA (year 1908) No. 44267 (Spain)

the secondary coil is wound in many thin flat pancake-shaped sections (called "pies"), connected in series. The primary coil is first wound on the iron core, and insulated from the secondary with a thick paper or rubber coating. Then each secondary subcoil is connected to the coil next to it, and slid onto the iron core,

Marathonman,


I find difficult to believe that someone has a working device, and he just contacted you in order to help you and he do not want to help the rest of users. Sorry but you are not the kindest person to deal with if someone do not share your ideas. That person supposedly told you his findings while you were trying another design.  I can guess that you surely did not accept those finding at first. I refer to your mood just by watching your behaviour with some users as NRamaswami, Darediamond, Sam, Antijon or even me when some of us just posted discrepancies with you transverse coil design (now abandoned by you) or just by advising you of some weak points to take into consideration as I tried to do. I will love to believe you and I would love to know that somebody had discovered the key. That was my aim by sharing all this in this thread. But I can not get it how you could have access to such info.
