From the recollection I have is that it was from the 1980’s period registered USA
Specially speaking it was a patent on a method of winding transformers and inductors
How I think the design outlined was {visually} two inductors on the same core in series but then linked in a parallel configuration
I specifically remember in the images an example A and B being a standard induction motor like which would be found in a microwave oven {or other} fan in the A example the comments stated that it was a common induction motor and required no other comments
In the B was explained the alternate winding scheme , there were also other examples.
The example gave the two winding methods from A to B and claimed due to the opposing induction {I think}
That less wire could be used
That’s the reason I’m looking for the patent, because I’m not sure if the series inductors were mutual or opposing, regardless I did see the patent but unless I wrote the number in one of my rambling books {haven’t looked yet} I cannot seem to find it again.
Anyone that knows of it or a link or a method to help find it would be greatly appreciated
Regards.
