    摘要: A sootblower for the cleaning of internal surfaces of large scale boilers which are subject to the accumulation of soot or slag encrustations. In instances where a sootblower is used to project the jet of steam of steam or a steam/air mixture, between actuation cycles, condensate can form in the sootblower or the associated piping. At the beginning of an actuation cycle the condensate is ejected from the sootblower. If the condensate impinges against the heat transfer surfaces inside the boiler it can cause damage to these surfaces through excessive thermal and mechanical shock. In accordance with this invention the sootblower is provided with a nozzle block assembly incorporating a condensate separator which causes condensate to be ejected by the lance tube away from impact with the heat transfer surfaces where it can be safely dissipated from the boiler without causing damage to the heat transfer surfaces which are cleaned using a substantially fully vaporous pure spray of sootblowing medium.

    摘要: A system and method for delivering geographically restricted content, including but not limited to over-air broadcast programming, to a recipient over a computer network, namely the Internet. The content is only delivered over the computer network if the recipient's computer or network device requesting the content over the network is verified to be located in the geographically restricted area. A conventional tuner is employed by the recipient's computer to receive one or more over-air signals having a broadcast range deemed to be synonymous with the geographically restricted area for the requested content. If the tuner is able to receive such over-air signal(s), the requested content is delivered over the network to the recipient's computer. This is because the recipient is known to be physically located in the geographically restricted area by the ability of the tuner to receive the over-air signal(s).

    摘要: A V.sub.BB input threshold potential with feedback circuitry is used to stabilize all of the logic inputs on an GaAs IC to ECL compatible levels over a normal temperature range and normal power supply variations. The system called "V.sub.BB -Feedback" uses "zero translation delay" direct Capacitor Diode Fet Logic (CDFL) inputs. This is an extension of the CDFL circuit approach in which the voltage across the input level shift circuitry on all inputs is adjusted to maintain a threshold voltage equal to the dc potential on an "extra" V.sub.BB input in spite of variations of temperature, power supply voltages or processing parameters such as MESFET pinchoff voltage. A dc potential (V.sub.BB) is applied to the "extra" V.sub.BB input, which is an additional input that is essentially identical to the actual logic inputs. All of the logic input threshold voltages are then slaved to the V.sub.BB dc potential applied to the "extra" V.sub.BB input. ECL compatability is accomplished by combining a reasonably compliant, but uniform, CDFL voltage shifter with feedback circuitry to maintain the shift voltages at proper levels thereby achieving the desired input logic threshold.
