Abstract

The device for treating fuel in a pipeline 8 comprises a collar 10 formed in two parts 12 securable together around the pipeline. The collar has on its inner periphery a series of four magnets 14 to provide a concentrated magnetic field at the centre of the pipeline. The magnets are formed of ferroceramic magnetic substances to provide a magnetic field of high flux density and retentivity. The magnets are arranged with the South magnetic face of each magnet facing inwardly for intensifying the magnetic field in a region through which the pipeline passes.

Description

This invention relates to magnetic arrangements for pipelines through which a hydrocarbon fuel is intended to flow and is for use in causing polarity alignment of the molecules in the fuel to increase the efficient use of fuel and improving its combustion.

Although the effect of improving combustion by polarity alignment of molecules in hydrocarbon fuels using magnetic fields is known, problems have arisen in efficiently adaptiny this effect to combustion engines in the fitment of such arrangements to combustion enyines and in creating a sufficiently strong enough magnetic field.

An object of the present invention is to obviate or mitigate these problems.

Accordingly, the present invention is a magnetic arrangement for a pipeline comprising a collar formed in two or more parts securable together around a pipeline# the collar having on its inner periphery a series of magnets to provide a focussed magnetic field at the centre of the pipeline.

Preferably, the magnets are formed of ferroceramic i maynetic substances to provide a magnetic field of high flux density and retentivity.

Preferably also, foiur magnets are provided arranged in such manner that the South magnetic face of each magnet faces inwardly and intensifies the magnetic field focussed within a passageway formed among the four I magnets through which the pipeline passes.

Preferably further, the collar is in two similar half parts, each having oppositely extending flanges and between corresponding matable flanges of the two parts fastening means are provided. The fastening means desirably comprises a slot provided in one matable flange and a tongue provided in the other matable flange, the tongue being engagable through the slot with the half parts movable relative to each other whereby the outer end of each tongue engages the land around the corresponding slot to hold the parts together. The parts may be fixed together in the fastened position.

The parts are beneficially encapsulated in a plastic : coating to prevent moisture penetration and to afford protection to the magnets.

An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:Fig. 1 is a perspective view of a magnetic arrangement according to the present invention, the arrangement being shown fitted around a pipeline and being shown without an outer coating for clarity; Fig. 2 is an end axial view of the arrangement i > _ ιΊ ς — ~L1 shown in Fig. 1; Figs. 3A and 3B are respectively side views of a detail of the arrangement showing opposed matable flanges in a spaced apart position and in a fastened position; and Fig. 4 is an end axial view of the arrangement including the outer coating.

Referring to the drawings, a magnetic arrangement for a pipeline 8 throuyh which a hydrocarbon fuel is intended to pass comprises a collar 10 formed in two similar half parts 12 securable together around the I pipeline 8. The collar 10 is of a metallic strap and has i on its inner periphery a series of magnets 14 to provide a focussed magnetic field at the centre of the pipeline 8. The magnets 14 are formed of ferroceramic magnetic substances to provide a magnetic field of high flux I density and retentivity, [ Four magnets 14 are provided arranged in such manner that the South magnetic face of each magnet 14 faces inwardly and intensifies the magnetic field focussed within a passageway formed among the four i I magnets 14 through which the pipeline 8 passes.

The half parts 12 of the collar 10 each has i oppositely extending flanges 16. Between each set of 25 corresponding matable flanges 16 of the two parts 12, fastening means are provided comprising a slot 18 provided in one matable flange 16 and a tongue 20 j r Μ ΙΊ Ο U s 1C Uz.cZ ο □ r ϋ r c ir r Ζ - U 5 ΙΕ 921651 ~ι ΓΊ ι U provided in the other matable flange 16. The tongue 2D is engagable through the slot 18 with the half parts 12 movable relative to each other whereby the outer end of each tongue 20 engages the land around the corresponding slot 18 (as shown) to hold the parts 12 together.

The shape of the collar 10, and therefore the parts 12, and the exact location of each magnet 14 is determined by calculation to suit particular applications and installations.

The magnets 14 are magnetised to have anisotropic formation with the polar axis aligned with the strap such that the concentrated South magnetic poles face inwardly and become additive and produce a very powerful unipolar flux field at the centre of focus. The ferroceramic material used is preferably, but not essentially, Feroba 3 anisotropic material of aero-space quality to provide remenance of the order of 1.5 Tesla and coercivity of 240KA/M and Curie temperature of better than 450 Celsius.

Additionally, the parts 12 are fixed together in the fastened position by, for example a headed grub screw (not shown) engaging through tapped bores in at least one set of matable flanges.

The parts 12 are encapsulated (as shown in Fig. 4) in a plastic coating to prevent moisture penetration and to afford protection to the magnets 14, the coating ί O r U y 3 iyyz-us-u i / ! U 1 i j ό - w O '□ w a IO having a thickness of better than 1 millimetre density.

A magnetic arrangement is fitted to an existing installation by first covering the pipeline with a length of longitudinally slit tubing 22 of, for example natural or synthetic rubber, and secondly fitting the parts 12 therearound as described above and as shown in Figs. 1 and 2.

A magnetic arrangement as described above is beneficial since it avoids the hitherto necessity of severing a pipeline of an existing installation and by use of the simple fastening means allows for rapid and simple installation. An advantage of the present invention is that it provides extremely high power magnets in a small physical size and which co-axially encircle the pipeline without, as mentioned above, the need for severing the pipeline. Also, if after being fitted the arrangement has to be removed, this can be done without permanent change or alteration to the original pipeline.

In a first modification, the collar may be in three parts each carrying a magnet, or four parts each carrying a magnet. Further, more than four magnets may be used, for example, for ease of manufacture, each magnet may be composed of two or more pieces provided that they each have the same magnetic relationship as shown in the drawings. f In a second modification, the collar may be of a different shape and the magnets may be other than cube shape as shown.

Variations and further modifications can be made without departing from the scope of the invention described above.
