    摘要： A curable composition includes a functionalized poly(arylene ether), an olefinically unsaturated monomer, about 0.2 to about 5 parts by weight of a curing initiator per 100 parts by weight total of the functionalized poly(arylene ether) and the olefinically unsaturated monomer, and about 0.005 to about 1 part by weight of a curing inhibitor per 100 parts by weight total of the functionalized poly(arylene ether) and the olefinically unsaturated monomer. The weight ratio of the curing initiator to the curing inhibitor is about 1.2:1 to about 50:1. The composition provides improved and reproducible flow during the early stages of molding without compromising curing time. The composition is useful for preparing plastic-packaged electronic devices.

    摘要： The present invention provides for a method for dosing an urea-based reducing agent into a exhaust gas stream generated from a combustion engine and addressed to an aftertreatment system, e.g. SCR or SCRT system. According to the method of the invention the gas exhaust stream is conveyed into a dosing housing which develops along a longitudinal axis. In particular the gas is conveyed by generating an annular inlet jet inclined with respect of said axis. The urea-based reducing agent is injected by generating, inside the housing, an urea-based reducing agent spray which is preferably coaxial to said axis of the housing.

    摘要： A quiescent melt handling system includes a melting furnace and a holding furnace communicating with the melting furnace for holding a molten metal melt. The holding furnace has a relatively large surface area and a relatively shallow depth, having a width to depth ratio in the range of 4-100 to 1. Also provided is structure in the holding furnace for separating inclusions from the melt in the holding furnace. A mold communicates with the holding furnace. A counter gravity casting system, which might comprise a vacuum assisted casting system, draws the melt into the mold.
