The invention relates to a device for reducing pollutant gas emissions by means of catalyst management in the combustion process, characterised in that it comprises: a hollow cylindrical body with a fuel inlet hole in one side of said cylindrical body and a fuel outlet hole in the other side of said cylindrical body; a perforated cylindrical separator inside said body; and a sheet formed by at least one magnetic element and which is situated between the perforated separator and the inner wall of the hollow cylindrical body, such that when the fuel flows inside the device, part of the components of the hydrocarbon magnetise.

A sintered annular magnet with a radial orientation of a remanent magnetic field, including: a principal annular part made from a ferromagnetic material, that has a first degree of magnetic anisotropy in the radial direction; and an annular reinforcing part fixed to the principal part of the magnet, the reinforcing part being made from same ferromagnetic material as the ferromagnetic material forming the principal part, and that has a second degree of magnetic anisotropy in the radial direction, the first degree being higher than the second degree.

Magnet arrangements, sensor devices and corresponding methods are provided comprising a first magnet portion and a second magnet portion. The first magnet portion is spaced apart from the second magnet portion, and the second magnet portion comprises a bore. In a corresponding sensor device, a sensor element may be provided at a position between the first and second magnet portions.

Disclosed are embodiments of synthetic garnet materials for use in radiofrequency applications. In some embodiments, increased amounts of gadolinium can be added into specific sites in the crystal structure of the synthetic garnet by incorporating indium, a trivalent element. By including both indium and increased amounts of gadolinium, the dielectric constant can be improved. Thus, embodiments of the disclosed material can be advantageous in both above and below resonance applications, such as for isolators and circulators.
