Abstract: The present invention relates to a polypropylene resin comprising a propylene/ethylene copolymer; an elastomer as impact modifier based on polypropylene or polyethylene and additives. The resin of the present disclosure is characterized by a flow index between 2 g/10 min to 10 g/10 min measured at 230° C.; density between 0.89 kg/m3 and 0.91 kg/m3; elongation percentage between 11% and 15%; flexural modulus between 792.9 MPa to 1034.2 MPa; tensile strength between 24.13 MPa and 27.58 MPa and Izod impact between 210 J/m and 350 J/m, making it useful in the manufacture of a wide range of products for the food, automotive, nautical, chemical, furniture and equipment, household appliances and sporting goods industries, among others.

Abstract: A technology is described for spatially estimating thermal emissivity. A method can include obtaining spectral emissivity data and satellite imaging data for a geographic area. A weighted emissivity model of emissivity values may be generated for surfaces included in the geographic area from the spectral emissivity data and the satellite imaging data, wherein the spectral emissivity data is mapped to the satellite imaging data to generate the weighted emissivity model. Thermal imaging data for the geographic area may be received from an airborne thermal imaging sensor and a thermal emissivity map can be generated for the geographic area using the thermal imaging data and the weighted emissivity model. The emissivity values from the weighted emissivity model can be used to estimate thermal emissivity values.

Abstract: Recovery of an ester feed stream, optionally with the recovery of ethanol, from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of the crude ethanol products are employed to allow recovery of the ester feed stream and for integration of the ester feed stream with an esters production process. The composition of the ester feed stream may vary, but at least comprises ethyl acetate and ethanol. The ester feed stream may be fed to one or more locations within the esters production process depending on the composition of the ester feed stream.

Abstract: A method of co-producing vinyl acetate and ethyl acetate includes: (a) reacting ethylene, acetic acid and oxygen to form vinyl acetate and at least a minor amount of ethyl acetate; (b) providing a crude product stream containing the vinyl acetate and ethyl acetate of step (a) and acetic acid to a distillation tower; (c) separating the crude product stream into: (i) a vinyl acetate product stream enriched in vinyl acetate with respect to the crude product stream; (ii) an acid recycle stream enriched in acetic acid with respect to the crude product stream; (iii) a mixed sidestream containing vinyl acetate and ethyl acetate, the mixed sidestream being enriched in ethyl acetate with respect to the vinyl acetate product stream; and (d) hydrogenating vinyl acetate in the mixed sidestream to provide an ethyl acetate product stream.

Abstract: An optically transmissive antenna including an optically transmissive aperture for a slot-type configuration antenna fabricated on a high transmission substrate; coplanar waveguide feedlines formed on the substrate, the coplanar waveguide feedlines defining a center portion and an exterior portion; a first connection point for connecting the center portion to a first conductor; and a second connection point for connecting the exterior portion to a second conductor. The substrate can be rigid or flexible. Also a method of making the antenna including the steps of selecting a high transmission substrate; sputtering the substrate with a highly transparent conductive layer; removing the highly transparent conductive layer from the substrate to form an aperture and a pair of coplanar waveguide feedlines for the antenna. The antenna can be connected using micro-coaxial cable.

Abstract: This invention relates to a process for the simultaneous coproduction of ethyl acetate and isopropyl acetate. The esterification reaction comprises contacting acetic acid with a mixed alcohol stream of ethanol and isopropanol. Exemplified is a purified, Fischer Tropsch derived mixture of ethanol and isopropanol. The esterification reaction occurs in the presence of an acidic catalyst in a liquid phase reaction system. The resultant crude reaction step product is separated and purified by distillation to produce acetate ester products having greater than 99.5 wt % purity.
