  • Patent number: 6623870
    Abstract: In general terms, the present invention includes a light emitting polymeric material the light emitting polymeric material capable of producing electroluminescence upon being provided with a flow of electrons, the light emitting polymeric material comprising a plurality of polymeric chains comprising polymeric chains each having substituent moieties of sufficient number and size and extending from the polymeric chain and about a substantial portion of the circumference about the polymer chain so as to maintain the polymeric chains in a sufficiently deaggregated state (referred to herein as a “strapped” polymer), so as to substantially prevent the redshifting of the electroluminescence and the lowering of light emission efficiency of the electroluminescence.

  • Patent number: 6621100
    Abstract: This invention relates to organic based spintronic devices, and electronic devices comprising them, including spin valves, spin tunnel junctions, spin transistors and spin light-emitting devices. New polymer-, organic- and molecular-based electronic devices in which the electron spin degree of freedom controls the electric current to enhance device performance. Polymer-, organic-, and molecular-based spintronic devices have enhanced functionality, ease of manufacture, are less costly than inorganic ones. The long spin coherence times due to the weak spin-orbit interaction of carbon and other low atomic number atoms that comprise organic materials make them ideal for exploiting the concepts of spin quantum devices. The hopping mechanism of charge transport that dominates in semiconducting polymers (vs. band transport in crystalline inorganic semiconductors) enhances spin-magneto sensitivity and reduces the expected power loss.

  • Patent number: 6598500
    Abstract: A device for operating on each nut of a double-nut assembly, wherein an inner nut of the assembly is of a diameter larger than that of an outer nut of the assembly. The device comprises two components: the first component is provided to act on the inner nut and is designed to allow a portion of the second component to pass therethrough, while the second component is provided to act on the outer nut. The first component may be used to rotate the inner nut to a desired position while a portion of the second component resides therein, whereafter the second component may be used to secure the rotated position by tightening the outer nut. The device may be used with an eccentric fastener assembly employing such a double-nut arrangement to set the toe angle of a vehicle wheel.

  • Patent number: 6598656
    Abstract: This invention relates to methods and apparatus useful in the ceramics industry. More specifically, this invention relates to the fabrication of high melting, wear-resistant ceramics and ceramic composites at low temperatures. The method involves reacting (1) a fluid formed from melting a metal alloy, comprising at least one reactive metal and at least one non-reactive metal, and having a melting temperature substantially below the product material melting point, typically below about 1500 C., with (2) a rigid, porous material. The reaction should occur for a sufficient time to allow the liquid to infiltrate the porous material and allow the active metal(s) to react with the porous material so as to form a ceramic or ceramic composite having a melting temperature substantially higher than 1500 C.
