It is theoretically possible to impart such
cycloidal motion but the "forever" part
may be a huge problem.  Magnetrons make
use of the concept with magnetic and electric
fields.

Seems the principle of work of a magnetron is (also) very simple (they are rather cheap) but nevertheless not obvious to everyone.

Good out of the box thinking though.

Hence a little bit more thinking out of the box: Electrons can be influenced either by a magnetic field or by an electric field or by both. An electric field can be generated by high voltage, a magnetic field can be generated by a transformer.

Now what if the electric field created by the high voltage attracts the electrons from ground (cathode) and the magnetic field of a transformer keeps them in a closed loop (anode)?

Sounds rather easy since the electrons can stay in a wire all the time, no vacuum necessary.

Normally a closed loop around a transformer (a shorted secondary coil) would waste energy due to unnecessary heat generation. The magnetic field generated by the current in the shorted secondary coil opposes the cause of its creation, namely the magnetic field generated by the primary coil (Lenz's law). But what if the magnetic field generated by the secondary coil is not due to the primary coil's magnetic field but due to additional electrons (current) coming from the ground? Does Lenz's law still apply?

Not sure I quite follow your idea completely, but I would like to plant a seed of out of the box thinking.  If you instead of putting a plate of high voltage at one end and a cathode at the other end of a line, as in a CRT;  what about putting a high voltage point in the center of a circle, and using coils/magnets to curve the travel of an electron path into an orbit around the high voltage point in the center?  Just something to think about.  But where would the cathode be placed in such an arrangement, near the orbit path?  (Also remember the cathode in a CRT is painted with a chemical that has electrons that boil on the cathode when heated).

In essence the idea is what the Barbosa patent says, but unfortunately not straightaway in layman's terms. I have the feeling a part of the explanation/description is missing in this patent.

Another device which utilized the
concept is the old Cyclotron.

It did require an input of energy in
order to keep the charged particles
in motion.

So unless the electron has a high voltage source to chase in a closed loop, it would not be possible.

Wrong.
A strong magnetic field will confine any moving charged particle (e.g. an electron) to a circular orbit.  If the particle does not lose energy due to collisions or Bremsstrahlung radiation, then the orbit will be stable.  See the photo below.
