Abstract: An aircraft wing is provided with a positionally fixed closure fairing to close a cut-out opening in the leading edge of the wing associated with a wing leading edge slat so as to direct incident airflow to the wing leading edge from a lower surface of the aircraft wing to an upper surface of the aircraft wing.

Abstract: A transaction processing system capable of processing transactions and implementing a flexible circuit breaker process during an event. A circuit breaker module initiates a circuit breaker event (CBE), an account identification module identifies one or more affected account IDs, and a rule generation module generates conditional rules for evaluating each transaction presented to a transaction processing module. If a transaction presented to the transaction processing module satisfies the conditional rule, the transaction is not processed. Transactions not processed are stored in memory and groups of impacted transactions are assigned to resource modules based on common characteristics. The resource module determines if impacted transactions should be allowed to process.

Abstract: A stripline radial power combiner is provided. The stripline radial combiner comprises a first stripline level comprising N radial combiner arms coupled to a first common node; a second stripline level comprising a common port coupled to a second common node; wherein the first stripline level is mounted over the second stripline level; and wherein the first common node and the second common node are coupled by a conductive via through the first stripline level and the second stripline level.

Abstract: A double valve assembly for regulating the feed of particulate material to or from a pressure vessel comprises a valve casing containing a flow-regulating valve and pressure sealing valve in series. Particulate material is fed to the valve assembly through a feed tube located at the top of the casing. The flow-regulating valve comprises a dish-shaped valve member swingable from a first position wherein it confronts the bottom of the feed tube and blocks flow of material therethrough to a second position at one side of the feed tube. The bottom of the feed tube is constructed and arranged to guide the particulate material away from the second valve position and thereby facilitate swinging movement of the swingable member from its first to its second position.

Abstract: Apparatus for breaking apart agglomerations of particulate matter flowing in a vessel (particularly useful ina pressurized moving-bed vertical-shaft reduction reactor for the production of sponge iron) is exemplified by an externally mounted hydraulic cylinder having access to the interior of said vessel through a probe port, the piston of said hydraulic cylinder being provided with a conical probe positioned so as to be normally retracted out from the interior of said vessel but extendable by said hydraulic cylinder into and across the interior of said vessel, preferably at the narrowed discharge portion thereof, whereby said probe is angled to extend downwardly in the direction of flow of said particulate matter as well as across said flow to engage and break up any agglomerations of particulate matter in its path.

Abstract: A method for inhibiting carburization of metal-bearing material in the reduction zone of a vertical shaft, moving bed reactor for the direct gaseous reduction of iron ore to sponge iron. Carburization within the reduction zone is decreased by regulating the water vapor content of the reducing gas in any of various ways, e.g., by adding water vapor in the form of steam to the reducing gas either before it enters the reduction zone, while it is within the reduction zone, or after it leaves the reduction zone or by recirculating a portion of the effluent gas from the reactor and cooling the recirculated gas to a predetermined extent.
