In one minute
Every claim in the granted motionless electromagnetic generator patent is a claim to a thing — a generator comprising a magnet, a core, coils. This continuation claims the same disclosure as a method: not the apparatus but the sequence of driving current alternately through two input coils so that each pulse opposes the permanent magnet's flux in its own path, and taking current from the resulting swings in two output coils. The shift matters more than it sounds, because it is what lets the self-running arrangement be claimed as a procedure rather than as a box. Claims four through six set that procedure out in order: start the switching and control circuit from an external source, rectify one part of the output to drive that circuit thereafter, rectify a second part to a load, and take the two parts from the two different output coils. The application was filed in February 2002, published in March 2004, and abandoned.
Connection
Chapter 6 already teaches the device. This document is what the inventors were trying to protect once they had it: the operating procedure and the feedback arrangement, stated as the steps a builder would follow rather than the parts a builder would buy — which is the form a reader needs if they want to know what was actually being proposed, as distinct from what was measured.
From the source
The independent method claim states the operating sequence as a procedure: drive current alternately through a first and second input coil wound on two U-shaped magnetic structures that run between the opposite poles of a permanent magnet, so that the current in each coil produces a field opposing the concentration of the magnet's flux in its own path, and take induced current from an output coil on each path. Nothing turns, and the magnet is never overpowered.Claim 1
The self-driving arrangement is claimed as four ordered steps rather than as a circuit diagram. The switching and control circuit is driven by an external power source during starting; a first portion of the output current is rectified to form a first rectified output; the switching and control circuit is then driven by that first portion once starting is complete; and a second rectified portion flows through an external load, with the two portions taken from the two different output coils. That is the whole of the self-running proposal, in the order a builder would perform it.Claims 4, 5 and 6
The materials and timing are claimed as limitations on the method, which is where the engineering specifics sit. Each U-shaped structure may be a nanocrystalline magnetic alloy, either a cobalt-niobium-boron alloy or an iron-based one; the input coils are alternately driven for periods of approximately 11.5 milliseconds; and the flux changes are required to occur without driving either path to magnetic saturation. Staying below saturation is the condition that keeps the switching cheap.Claims 7 to 11
A second independent claim covers the stacked geometry as a method. Two spaced-apart plate sections, each around an aperture, are joined by posts and permanent magnets alternating around the ring, so every post sits between a pair of magnets and every magnet between a pair of posts, with all the magnets aligned the same way. An output coil goes on each post; the input coils sit on the plate sections between a magnet and a post and are wound to oppose the flux through themselves, in two groups driven alternately. Two further claims fix whether both groups sit on the upper plate or one on each.Claims 12, 13 and 14
