Abstract
Abstract A fuel treating device comprises two pairs of magnets, one pair positioned on each inlet for fuel and oxygen so that the incoming fuel is exposed to a magnetic field. Each pair of magnets is positioned diametrically opposed about the inlet line with the south magnetic pole of each magnet placed upstream furthest away from the mixing zone. The magnets are insulated from each other and from the inlet line by nonmagnetic materials, such as Neoprene, which do not disrupt the magnetic field.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
77 words
A fuel treating device for a combustion chamber having a hydrocarbon fuel inlet line and an oxygen inlet line, comprising: a pair of substantially diametrically opposed magnets longitudinally positioned around the fuel inlet line with the south magnetic pole of each magnet located furthest from the combustion chamber; and a pair of substantially diametrically opposed magnets longitudinally positioned around the oxygen inlet line with the south magnetic pole of each magnet located furthest from the combustion chamber.
Claim 2
Dependent Claim
77 words
A fuel treating device for a combustion chamber having a hydrocarbon fuel inlet line and an oxygen inlet line, comprising: a pair of substantially diametrically opposed magnets longitudinally positioned around the fuel inlet line with the south magnetic pole of each magnet located furthest from the combustion chamber; and a pair of substantially diametrically opposed magnets longitudinally positioned around the oxygen inlet line with the south magnetic pole of each magnet located furthest from the combustion chamber.
Claim 3
Dependent Claim
20 words
The fuel treating device as defined in claim 1, further comprising nonmagnetic spacers to retain the magnets substantially diametrically opposed.
Claim 4
Dependent Claim
20 words
The fuel treating device of claim 1 or claim 2 wherein each magnet has a layer of insulation enclosing it.
Claim 5
Dependent Claim
27 words
The fuel treating device of claim 1 or claim 2 wherein the fuel inlet line and oxygen inlet line are insulated from direct contact with the magnets.
Claim 6
Dependent Claim
33 words
