摘要:
The present invention relates to a filler masterbatch composition comprised of a polymer selected from an impact polypropylene, a high density polyethylene, and a polyolefin elastomer and a mineral filler and a filled thermoplastic composition produced by combining such a filer masterbatch composition with a polymer. The inventive filler masterbatch allows for a higher compounding rate, better dispersion, and elimination of a typical compounding step in the production of filled thermoplastic compositions.

A gas turbine combustion system having reduced emissions and improved flame stability at multiple load conditions is disclosed. The improved combustion system accomplishes this through complete premixing, a plurality of fuel injector locations, combustor geometry, and precise three dimensional staging between fuel injectors. Axial, radial, and circumferential fuel staging is utilized including fuel injection proximate air swirlers. Furthermore, strong recirculation zones are established proximate the introduction of fuel and air premixture from different stages to the combustion zone. The combination of the strong recirculation zones, efficient premixing, and staged fuel flow thereby provide the opportunity to produce low emissions combustion at various load conditions.

A method and apparatus for division of revenue of communication among different proprietors is provided in this invention, where the division of revenue among the different proprietors is performed by a gateway office, wherein the gateway office will set a source parameter and a destination parameter respectively from the source and the destination when a call goes through the gateway office; Judge the two parameters to get a revenue zone index; Judge the value of the revenue zone index, and modulate the revenue zone index to get a revenue class index; The gateway office generates contents related to the revenue class index; A central memory receives all these contents, adds an increment of each counter of the revenue class memory related to the revenue class index to a corresponding counter and carries out multiple safety mechanisms; Output the information in the revenue class memory to a storage medium for storing, then output it to a billing center for revenue sorting. The billing mode present in this invention is based on group pairs, so it is more adaptive for the gateway office to divide revenue.
摘要:
A method for protecting high temperature stainless steel from coking and corrosion at elevated temperatures in corrosive environments, such as during ethylene production, by coating the stainless steel with an overlay coating of MCrAlX in which M is nickel, cobalt, iron or a mixture thereof and X is yttrium, hafnium, zirconium, lanthanum or combination thereof. The overlay coating and stainless steel substrate are heat-treated to metallurgically bond the overlay coating to the substrate and to form a multiphased microstructure. The overlay coating preferably is aluminized by depositing a layer of aluminum thereon and subjecting the resulting coating to oxidation to form an alumina surface layer. An intermediary aluminum-containing diffusion coating may be deposited directly onto the stainless steel substrate prior to deposition of the overlay coating to form a protective interlayer between the stainless steel substrate and overlay coating.

A method is disclosed for extending a primer to produce a single stranded polydeoxynucleotide that has two or more defined sequences. A combination is provided which comprises a template polynucleotide, a blocker polynucleotide, a primer polynucleotide and a polynucleotide Q. The template polynucleotide has three sequences T1, T2 and T3 wherein T1 is non-contiguous and 3' of T3 and wherein the 5' end of T3 is 5' of the 5' end of T2. The primer polynucleotide has a second defined sequence at its 3' end that is hybridizable with T1. The blocker polynucleotide has sequence B1 that is hybridizable with T3. Polynucleotide Q has sequences S1 and S2 wherein S1 is 3' of S2 and homologous with T2 and S2 is complementary to a first defined sequence that is to be introduced at the 3' end of the polynucleotide primer, when it is extended during the method of the invention. Polynucleotide Q is either attached to the 5' end of the blocker polynucleotide or present as a separate reagent. The primer is extended along the template polynucleotide and along at least a portion of sequence T2 and thereafter along the polynucleotide Q to give a single stranded polynucleotide having two or more defined sequences.
