  • Orientation independent liquid fuel reservoir
    Patent number: 7291410
    Abstract: A fuel reservoir for a liquid fuel cell particularly useful for portable electronic devices or for a reformer, includes (a) a container defining a volume for holding a liquid fuel; (b) a wicking structure positioned within the volume and into which at least one portion of the liquid fuel wicks and from which said liquid fuel subsequently may be metered, such as by pumping; (c) a retainer to hold the wicking structure in a desired orientation within the container; and (d) an outlet for the liquid fuel that is in communication with the wicking structure. A method of dispensing liquid fuel and a method of assembling a fuel cartridge are also disclosed.
    Type: Grant
    Filed: September 22, 2003
    Date of Patent: November 6, 2007

  • Glycoside compounds and methods of synthesis
    Patent number: 6093805
    Abstract: Novel glycosides, especially steroidal and non-steroidal glycosides are provided. The steroidal and non-steroidal glycosides preferably are prepared from aglycons which possess valuable properties such as pharmacological properties. The glycosides are prepared from useful aglycons and possess useful properties which are the same as those of their respective unglycosylated aglycons. The glycosides are provided in acylated and deacylated form. The acylated glycosides after hydrolysis of the acyl groups possess enhanced water solubility properties, as illustrated in the case where the aglycon is acetominophen.
