    摘要: An omni-directional antenna includes an electrically conductive ground plane, an electrically conductive parasitic disc spaced upwardly apart from the ground plane and parallel thereto, and an electrically conductive vertical antenna element extending up through the center of the ground plane and parasitic disc, The vertical element terminates in a tip defining a length above the parasitic disc that is matched to a frequency of interest. The parasitic disc and ground plane are preferably both circular. To prevent electrical connection, the vertical element preferably extends through separate insulators in the parasitic disc and ground plane. The length of the vertical element is matched to a microwave frequency; in particular, the length of the vertical element is proportioned to one-quarter wavelength of the frequency of interest. The invention is particularly suited to microwave frequencies.

    摘要: The irrigation system includes a threaded neck, a main chamber, a 360-degree tube coupling, a set of directional flow tubes, a flow tube nozzle adjustment, a chamber pressure control, and a pulse flow control dial. The multi-flow system is useful for providing a direct watering system in a garden will not damage or over-water plants. Further, the system decreases water loss, and helps maintain proper plant health by adding fertilizer to the system if so desired.

    摘要: There is provided a quartz glass article having a surface treated with novel coating materials which provides a reduced chemistry, wherein the quartz glass surface having a reduced chemistry upon exposure to melted silicon or similarly corrosive environments, forms crystalline structures covering at least 75% of the coated surface of the quartz glass crucible. Said crystalline covered surface provides a more stable surface of contact with the silicon melt and the growth of single crystal silicon. In one embodiment of the invention, the coating material comprises at least a methyl group for providing at least one of a hydrogenated and a methylated surface on the coated surface, forming rosette structures, or other crystalline morphologies covering at last 80% of the coated surface. In another embodiment of the invention, the coating material is selected from at least one of an amine, an organosilane halogen and mixtures thereof.
