20140238267 | METHOD OF MANUFACTURING SOIL REINFORCED BY MICROBE-BASED BIO-BINDERS AND SOIL PRODUCED BY THE METHOD - The present invention relates to a method of manufacturing soil reinforced by microbe-based bio-binders and soil produced by the method. The bio-binders are not harmful to humans, do not cause environmental pollution and secure sufficiently the soil strength and resistance against wind. According to the method, the soil is prepared by binding sand whose major components are silica and alumina, ureolytic microbes, urea, calcium ion, and polymer fibers, and the content of polymer fibers in sand ranges from 0.05 wt % to 5 wt %. In addition, it is preferable that the microbes provide CaCO | 08-28-2014 |
20120176286 | Dielectric loaded shorted bicone antenna with laterally extending ground plate - A bicone antenna, having: a tapered top cone; a tapered bottom cone; a laterally extending ground plate beneath the tapered bottom cone; at least one shorting pin connecting the tapered top cone and the tapered bottom cone; a central pin connected to the tapered top cone; a coaxial feed connected to central pin and the laterally extending ground plate; and a dielectric disposed between the tapered top cone and the tapered bottom cone. | 07-12-2012 |
20100235293 | METHOD AND APPARATUS FOR GENERATING STANDARDIZED CARBON EMISSION REDUCTION CREDITS - A method and apparatus for determining standardized carbon emission reduction credits is disclosed. General regional data and site-specific data, if available, are input into a carbon sequestration model to determine the approximate change in the level of carbon compounds stored in a media, such as soil, over a specified period of time. An uncertainty analysis is conducted on the results to quantify and normalize carbon emission reduction credits. Standardized carbon emission reduction credits may be compiled for trade and other carbon emission reduction credits are placed in reserve. | 09-16-2010 |
20100139087 | Microwave Device for Rapid Prototyping - A system of rapid prototyping, having: a plurality of thin sheets of low loss dielectric film, each sheet having a different metallization pattern formed thereon; and a base onto which each of the plurality of thin sheets of low loss dielectric film can be received, wherein the base comprises a metallization pattern formed thereon, and wherein placement of each of the plurality of thin sheets of low loss dielectric film onto the base results in a different circuit being formed across the thin sheet and the base. | 06-10-2010 |
