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.

摘要： A spreadsheet application associates data obtained from a captured image with a spreadsheet. For example, one or more images of physical data may be captured and translated into electronic data that is automatically associated with one or more spreadsheets. The formatting and underlying formulas of the data included within the captured image may be represented within a spreadsheet (e.g. highlighted data remains highlighted within the electronic spreadsheet). The data may also be compared with existing electronic data. For example, differences between the data in the captured image with the data in an existing spreadsheet may be used to update the existing spreadsheet. A display of a captured image may be also be augmented using data that is obtained from the captured image. For example, a chart may be created and displayed using data that is obtained from the captured image.
