  • Publication number: 20120107224
    Abstract: Methods to at least partially reduce a niobium oxide are described wherein the process includes mixing the niobium oxide and niobium powder to form a powder mixture that is then heat treated to form heat treated particles which then undergo reacting in an atmosphere which permits the transfer of oxygen atoms from the niobium oxide to the niobium powder, and at a temperature and for a time sufficient to form an oxygen reduced niobium oxide. Oxygen reduced niobium oxides having high porosity are also described as well as capacitors containing anodes made from the oxygen reduced niobium oxides.

  • Patent number: 5201814
    Abstract: The present invention provides a non-complex, simple to use and economical coupling device or connecting two elements, which provides for disconnection of the two elements when the tension applied to the coupling device exceeds a predetermined load. The coupling device includes an outer and an inner sleeve each having an axial bore. The lower end of the inner sleeve is slidably disposed within the upper end of the outer sleeve and the sleeves are relatively moveable. A frangible elongated member with a predetermined tensile strength connects the outer and inner sleeves through the axial bores. The frangible member breaks under a predetermined amount of stress thereby allowing the outer and inner sleeves of the coupling device to separate and disconnecting the attached elements. One or more internal longitudinal passages through the outer and inner sleeves adjacent to the axial bores allow passage of wire cables, gases, fluids or mechanical linkages through the coupler.
