  • HIGH TEMPERATURE SUPERCONDUCTOR
    Publication number: 20240122080
    Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.

  • Band saw blade tensioning device
    Patent number: 5557989
    Abstract: A device for securing and tensioning a band saw blade, including a rectangular base member having a longitudinal axis, and a disk member fixedly attached at one end of the base member, the disk member holding a first end of the band saw blade in place. A first pair of parallel blade guides is disposed parallel to the longitudinal axis of the base member for supporting a section of the band saw blade therebetween. A retractable tensioning mechanism is disposed at the other end of the base member, which produces an outwardly directed force on a second end of the band saw blade.
