CLEMENTE FIGUERA PATENT (1902) No. 30375 (SPAIN)

NEW PROCEDURE FOR OBTAINING ELECTRICAL CURRENTS IN GENERAL AND APPLICABLE TO INDUSTRIAL USES DESCRIPTION

All systems adopted, until the present, to produce electric currents, are based on the well-known principle that, when a core of soft iron which approach or moves away from a magnet is magnetized and demagnetized do appear induced current in any copper wire which is coiled in said core. This is the fundamental principle of the Clarke machine, of the company “The Alliance”, and the current dynamos, which, like all others, are machines to transform mechanical force into electricity. In all of them, the magnetizations and successive demagnetizations of the core or cores is achieved approaching and moving away these permanent magnets or electromagnets, called excitatory.

Those who sign, have devised a new method or process for producing magnetic changes in the core, and this procedure consists of making intermittent or alternating the current which drives the excitatory electromagnets, in which case neither the nuclei, nor the induced circuit need to be moved at all.

The whole question comes down to change the state of magnetization of the cores, so that electrical currents could appear in the induced wire. Until now, this result is achieved by making the core or cores approaching or moving from the magnetic centers created by the excitatory electromagnets. We, through an intermittent or alternating electric current achieve a variation in the magnetic state of the cores of the excitatory electromagnets, and also changing, the magnetic state of the cores on which the induced circuit is coiled, where electric currents appear ready to be industrially exploited.

As the soft iron core of a dynamo becomes a real magnet from the time when current flow along the wire of the induced circuit, we think that this core must be formed or constituted by a group of real electromagnets, properly built to develop the highest possible attractive force, and without taking into account the conditions to be fitted in the induced circuit, which is completely independent of the core.

The procedure is thus reduced to establish an independent induced circuit, within the sphere of action or magnetic atmosphere formed between the magnetic pole faces, of opposite name, of two electromagnets, or series of electromagnets driven by intermittent or alternating currents.

In current dynamos, the coils of the induced circuit cut the force lines which go from the faces of the excitatory electromagnets to the core; in our procedure, the same lines of force, which are born and die cross through the coils on the induced.

The novelty of our procedure is as follows:

1. In that, you do not need to use any driving force, since the machines built according to these principles will not act as transformers of work into electricity.

2. In that, until the present, none has tried to change, at industrial scale, from zero, the magnetic power of the excitatory magnets or electromagnets of a running machine.

Note: for which the patent is filed

Procedure to achieve electric currents, establishing a motionless and independent induced circuit, within the sphere of action or magnetic atmosphere formed between the magnetic pole faces of two excitatory electromagnets, or series of motionless electromagnets, powered by intermittent or alternate currents.
