Scott Technology Assigned Patent

Scott Technology NZ Limited, Kenmure, Dunedin, New Zealand, has been assigned a patent (10,408,891) developed by Fee, Michael Graeme, and Dickie, Oliver John, Wellington, New Zealand, for an “apparatus for testing sample properties in a magnetic field.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A magnetic testing apparatus includes a magnet assembly with a sample path extending through the magnet assembly. The magnetic field produced by the magnet assembly defines a known, varying magnetic field profile along the sample path. A sample is moved along sample path such that the sample portion is subjected to a predetermined magnetic field ramp or magnetic field profile during a measurement period. A measurement arrangement is also provided to measure one or more properties of the sample during the measurement period, in order to test sample properties at a plurality of different magnetic fields. The apparatus may be particularly suited to magneto-optical measurements, including Magneto-Optical Kerr Effect measurements. The apparatus may be used for testing of hard disk platters.”

The patent application was filed on July 15, 2014 (14/906,113).
