Abstract: Methods and systems for fuel vapor canister purging in boosted engines are described. In one example, vapors are purged from the canister into an engine intake passage downstream of a throttle via an ejector during vacuum conditions, whereas during boost conditions, vapors are purged from the canister into an upstream inlet of a compressor via the ejector, the compressor arranged in the intake passage upstream of the throttle.

Abstract: The present invention serves as a framework for both an extensible markup language interface for web services and to access objects. Using web services and objects, the present invention allows two or more computer networks to communicate with each other regardless of the security status of the networks. The present invention collects information from the networks by classes of objects and transmits information between the networks without rendering a network less secure. The present invention is coded in the WSDL language and communicates upon the SOAP protocol.

Abstract: An impact flowmeter includes a housing having an inlet end, an outlet end, and an interior region. The flowmeter also includes an inlet chute coupled to the inlet end of the housing. The inlet chute has an open end for discharging material into the interior region of the housing. The flowmeter further includes a load cell coupled to the housing for generating an output signal, and an impact plate coupled to the load cell. The impact plate is aligned with the inlet chute so that material entering the housing strikes the impact plate. The impact plate deflects the load cell in a measurement direction to change the output signal from the load cell based on the flow rate of material. The flowmeter still further includes a stop for biasing the load cell in the measurement direction to establish a preload condition on the load cell, thereby reducing the affect of vibration on the output signal from the load cell.

Abstract: A scale apparatus is provided for weighing material moving in a downstream direction on a conveyor belt supported by a conveyor frame. The apparatus includes an upstream idler station, a downstream idler station, and a measuring idler station situated between the upstream idler station and the downstream idler station. The apparatus also includes a mechanism for measuring the weight of material moving on the conveyor belt. The measuring mechanism is coupled to the measuring idler station. The upstream idler station, the measuring idler station, and the downstream idler station are coupled together to form a scale unit. The scale unit is coupled to the conveyor frame so that the conveyor belt passes over the upstream idler station, the measuring idler station, and the downstream idler station.
