Patent application numberDescriptionPublished
20100244983CONSTANT IMPEDANCE FILTER - A method and apparatus to provide a bi-directional constant impedance filter. Embodiments include electric networks which give filter responses while presenting a constant impedance to a signal received at either an input or an output port for a plurality of frequencies.09-30-2010
20100246413TRANSMISSION LINE SIMULATOR - A method and apparatus to simulate a length of telecommunications line. One or more bi-directional constant input impedance low pass or pole/zero filters are coupled in series with an attenuator to simulate a length of telecommunications line. The one or more filters are used to approximate the transfer function of the length of telecommunications line.09-30-2010

Patent application numberDescriptionPublished
20090215626High-load glyphosate formulations - By the present invention, a surfactant system containing glyphosate has been created which can be used to yield formulations containing an ultra-high load of glyphosate, in which the glyphosate concentration is higher than previously possible in any agriculturally-acceptable formulation. Higher loadings are desirable to reduce shipping and container costs, as well as reduce wastes. The higher loading reduces storage requirements and allows the farmer to handle less volume of pesticide. The main advantage is that maximizing the loading minimizes the cost to deliver the active ingredient, which in turn maximizes economy in use of glyphosate.08-27-2009
20090325808OSTWALD RIPENING INHIBITION IN CHEMICAL FORMULATIONS - A formulation having a slightly water soluble ingredient and method for preparing the same are disclosed. The millbase formulation comprises a slightly water soluble ingredient and a dispersant comprising a water soluble or water dispersible, derivative of an alternating copolymer or a salt thereof. The alternating copolymer comprises a residue of a first comonomer and a residue of a second comonomer. In addition, the first comonomer comprises an α,β-unsaturated oxyacid, or an anhydride or other derivative thereof. Moreover, the second comonomer comprises an olefinic compound containing one or more polymerizable double bonds, or a derivative thereof. Such formulations may be used to inhibit Ostwald ripening in agricultural as well as non-agricultural applications.12-31-2009
20100009937PESTICIDE FORMULATION WITH STREAMING BIREFRINGENCE - A pesticide composition exhibiting streaming birefringence and methods for making the pesticide composition are disclosed. In one embodiment, the pesticide composition comprises an active ingredient and a surfactant adjuvant.01-14-2010
20100105559LIQUID CRYSTAL AGROCHEMICAL FORMULATIONS - An agrochemical composition includes a homogeneous single-phase liquid crystal in thermodynamic equilibrium. The agrochemical composition can be a surfactant composition or a pesticide composition. The surfactant composition is a blend of surfactants, whereas a pesticide composition has an active ingredient and one or more surfactant adjuvants. A pesticide composition, or a surfactant composition in combination with an active ingredient, may be used to control pests.04-29-2010
20100279870METHOD OF PREPARING AMIDOAMINE ALKOXYLATES AND COMPOSITIONS THEREOF - A method of producing an amidoamine alkoxylate is disclosed that involves reacting a triglyceride, a carboxylic acid, or a combination of triglyceride and carboxylic acid with an alkyleneamine to produce an amidoamine and alkoxylating the amidoamine with an alkylene oxide. Also disclosed are amidoamine alkoxylate compositions and their use in agricultural formulations.11-04-2010
