Latest Patents

Julian Cave's latest patents include revolutionary developments in amorphous alloys. His first patent focuses on the creation of an Amorphous Fe100-a-bPaMb alloy foil and methods for its preparation. This alloy, characterized by variable parameters 'a' (ranging from 13 to 24), 'b' (from 0 to 4), and 'M' which consists of at least one transition element other than Fe, has outstanding properties. It is established as amorphous through X-ray diffraction, boasts an average thickness greater than 20 micrometers, and exhibits a tensile strength ranging between 200-1100 MPa. Additionally, the electrical resistivity exceeds 120 µΩcm, combined with a high saturation induction (B) above 1.4 T, a coercive field (Hc) under 40 A/m, and minimal loss (W) at power frequencies (60 Hz), ensuring it is less than 0.65 W/kg for a peak induction of at least 1.35 T. Its impressive relative magnetic permeability is greater than 10000 for low values of µH.

Furthermore, Cave holds a patent for a cryogenic current limiting fuse, which describes a method of manufacturing this technology. This fuse comprises a first and second cryogenic composite, where at least one of them exhibits non-linear and increasing resistivity with respect to temperature and current, showcasing his contribution to advanced electrical applications.
