At higher nanotube concentrations (i.e., about 0.6 wt % or more), the composites are non-transparent.Type: GrantFiled: December 1, 2006Date of Patent: July 13, 2010Assignee: University of South FloridaInventors: Julie P. Harmon, LaNetra M. Clayton

Publication number: 20100163402Abstract: A system for producing a substitute fuel includes a loop reactor system that includes a loop type reactor equipped with at least one dual frequency irradiator to mix the reactants uniformly in the reactor and to accelerate the reaction. The system further includes an apparatus for feeding waste oil containing free fat acid or fat oil containing triglyceride, and an apparatus for feeding catalyst and methanol. A separation/extraction system is provided for separating the products produced in the loop reactor system into large and small particles and vaporizing low boiling point components. A phase (layer) separation system is provided for stabilizing the products. This system is equipped with a dual frequency phase separator and a vertical double baffle.Type: ApplicationFiled: April 5, 2007Publication date: July 1, 2010Inventor: Eun Ju Seo

Patent number: 7744729Abstract: An acoustic system for applying vibratory energy including a horn connected to an ultrasonic energy source. The horn defines an overall length and wavelength, and at least a leading section thereof is comprised of a ceramic material. The leading section has a length of at least ? the horn wavelength. In one preferred embodiment, an entirety of the horn is a ceramic material, and is mounted to a separate component, such as a waveguide, via an interference fit. Regardless, by utilizing a ceramic material for at least a significant portion of the horn, the ultrasonic system of the present invention facilitates long-term operation in extreme environments such as high temperature and/or corrosive fluid mediums. The present invention is useful for fabrication of metal matrix composite wires.Type: GrantFiled: October 16, 2007Date of Patent: June 29, 2010Assignee: 3M Innovative Properties CompanyInventors: Satinder K. Nayar, Ronald W. Gerdes, Michael W. Carpenter, Kamal E. Amin
