  • Patent number: 3964553
    Abstract: Borehole orienting apparatus is provided wherein motion is imparted to a permanent magnet assembly to generate a moving magnetic field and receiver means are provided such that measurable signals are induced therein when the magnetic field is distorted due to the presence of a ferrous anomaly. The receiver means is rotated to produce an azimuthal scan such that there are induced in the receiver means signals from which the azimuthal location of the anomaly can be determined.

  • Patent number: 3951870
    Abstract: Fine diameter continuous multifilament superconductor yarns comprising niobium carbonitride may be prepared. The fibers of which the yarn is composed possess a very high transition temperature (T.sub.c of 17.degree.K) combined with a good upper critical field (H.sub.c2 of 125 kG) and critical current density (J.sub.c of 10.sup.5 amps/cm.sup.2 at 40 kG). This invention provides excellent superconductor materials in the form of continuous fine diameter multifilament yarn.
