  • Patent number: 6803108
    Abstract: Carbon fiber bundles may be dispersed into substantially single mono-filaments in pitch by stirring a mixture of fibers and pitch at a temperature at which the pitch has a viscosity of about 0.1 to about 5 poise. The resulting fiber pitch binder contains about 0.5 to about 10.0 wt. % carbon fibers substantially dispersed as substantially single mono-filaments which are randomly oriented which may then be used directly as a binder for producing carbon bodies, for example, graphite electrodes, pinstock or specialty graphite articles. This unique binder using an economical amount of carbon fibers has the capacity to increase the strength and reduce the coefficients of thermal expansion of the resulting carbon products in more than one direction due to the random orientation of the carbon fibers.

  • Patent number: 6803141
    Abstract: A method for producing ultra-high power density solid oxide fuel cells (SOFCs). The method involves the formation of a multilayer structure cells wherein a buffer layer of doped-ceria is deposited intermediate a zirconia electrolyte and a cobalt iron based electrode using a colloidal spray deposition (CSD) technique. For example, a cobalt iron based cathode composed of (La,Sr)(Co,Fe)O (LSCF) may be deposited on a zirconia electrolyte via a buffer layer of doped-ceria deposited by the CSD technique. The thus formed SOFC have a power density of 1400 mW/cm2 at 600° C. and 900 mW/cm2 at 700° C. which constitutes a 2-3 times increased in power density over conventionally produced SOFCs.

  • Patent number: 6803146
    Abstract: A battery terminal is configured to be secured to a battery case and includes a terminal assembly, and a ring. The terminal assembly includes an insert having a threaded bore, and an outer metal portion having a base with an annular flange configured to engage the inner surface of the case. The terminal further includes an anti-turn system with a first set of angularly-spaced bosses with intervening slots formed on a boss on the case, a second set of angularly-spaced bosses with intervening slots on a first side of the ring facing the case, which are complementary to the first set to form interlocking features. A set of recesses on the opposite side of the ring is configured to receive spun-over lead material during final finishing to form another pair of interlocking features. The exterior spun battery terminal eliminates corrosion that would otherwise occur due to cold worked lead contacting acid.

  • Patent number: 6803147
    Abstract: The current invention relates to the preparation of an improved cathode active material for non-aqueous lithium electrochemical cell. In particular, the cathode active material comprises &egr;-phase silver vanadium oxide prepared by using a &ggr;-phase silver vanadium oxide starting material. The reaction of &ggr;-phase SVO with a silver salt produces the novel &egr;-phase SVO possessing a lower surface area than &egr;-phase SVO produced from vanadium oxide (V2O5) and a similar silver salt as starting materials. Consequently, the low surface area &egr;-phase SVO material provides an advantage in greater long term stability in pulse dischargeable cells.

  • Patent number: 6803153
    Abstract: An optical storage medium of the present invention enables storage of data with high precision at high speed, and rewriting of data at high speed without an erasing process. Optical storage, reading and retrieving methods and optical storage, reading, and retrieving apparatuses using the medium are also provided. The optical storage medium has at least a polarization-sensitive member having the photo-induced birefringence property, such as a member made of polyester polymer having cyanoazobenzene as a side chain. The above apparatuses have spatial light modulator capable of modulating polarization. The modulator provides information of bit of two-dimensional data to each corresponding pixel by application or non-application of a voltage, and modulates the polarization of the beam incident on each pixel. Thereby, a signal beam transmitted through the spatial light modulator having a spatial polarization modulation corresponding to the two-dimensional data is obtained.
