A single-stage air scrubbing apparatus is provided that includes at least one reaction vessel, at least one introduction duct, and a turbulence component, wherein a residence time is sufficient to allow the conversion of at least one atmospheric pollution compound to at least one other compound, molecule or atom. In some embodiments, the at least one atmospheric pollution compound comprises nitrogen oxide, sulfur oxide or a combination thereof. Additionally, methods of removing atmospheric pollution compounds from a waste gas stream are disclosed that include introducing a waste gas stream and at least one additional gas stream, mist stream, liquid stream or combination thereof into a single-stage air scrubbing apparatus at a flow rate sufficient to allow for conversion of the at least one atmospheric pollution compound.

Abstract: A carbo-chlorination process is disclosed for selectively producing AlCl3 from an alumina-containing feedstock, comprising introducing the following into a fluidized bed reactor maintained at 600-700° C.: (a) dried and calcined feed stream comprising the alumina-containing feedstock and a carbon feed; (b) chlorinating agent; (c) selectivity agent; (d) dried air; and optionally (e) off-spec AlCl3. The process further includes removing a vapor stream from the reactor in which preferably about 75-80%, of the alumina present in the reactor is converted to AlCl3; and also removing a solid raw pozzolan stream from the reactor, wherein about 90-99% of the silica present in the reactor remains unconverted and exits the reactor through the solid raw pozzolan stream. The vapor stream comprising AlCl3 is purified to create an AlCl3 product stream comprising preferably greater than about 99.99% AlCl3.

Abstract: A method includes providing a measured dose amount of manufactured metallic nanoparticle material and adding the measured dose amount of the manufactured metallic nanoparticle material to a carrier material for pre-treatment of the carrier material prior to use of the carrier material and the manufactured metallic nanoparticle material in the sub-surface earth activity. Another method includes accessing a sub-surface earth opening that is used in conjunction with the sub-surface earth activity, introducing an amount of manufactured metallic nanoparticle material into the sub-surface earth opening, and treating a sub-surface earth condition present at a sub-surface earth location accessible via the sub-surface earth opening. The sub-surface earth condition is treated with the manufactured metallic nanoparticle material.

Abstract: Systems and methods for designing and controlling distributed generation resources are disclosed. Monolithic or distributed controllers control the power requests sent to each distributed generation resource to achieve optimal efficiency using rule-based and/or fuzzy logic-based control techniques. High-impedance fault (HIF) detection circuitry allows power export to the utility grid in normal operating circumstances, and when an islanding condition is detected, ceases that export within two seconds and prevents further export until the condition is cleared.

Abstract: A method, computer program product, and data processing system, with which a unified security policy may be implemented using existing application components with disparate security mechanisms and user registries is disclosed. The present invention provides a generic application programming interface (API) that forms a framework for creating registry adapters. Registry adapters allow a policy director (an item of software for imposing a sitewide security policy) to operate with new or unfamiliar registry types by acting as a drop-in translator for converting generic registry-access commands into operations specific to the particular registry in question.

Abstract: A method and system for sharing existing user and group registry information between heterogeneous application servers is provided. The method and system make use of an adapter that communicates with each registry associated with each application server through a registry communication mechanism. In a preferred embodiment, the present invention provides an additional application-specific database to protect application-specific data that is required for each application server's operation but is not part of an existing database registry. Both the application-specific databases and existing user and group definitions in a user and group registry form a new registry abstraction which is required for each application server. As a result, each application server automatically shares user and group definitions with the existing database server. Furthermore, both the database server and each application server maintain a centralized user and group management model across different application domains.

Abstract: An electrical connector assembly includes a pin header 10 that can be mounted in an opening 4 in an electrically conductive case 2. The pin header 10 includes a molded pin header housing 12 that can be used in unfiltered as well as filtered and shielded versions. The filtered and shielded versions include a ground shield 20 or 50 that includes segmented cantilever tangs 26 or 56 extending along peripheral edges of the shield member 20 or 50. These tangs 26 or 58 mechanically grip the electrically conductive case 2 to establish ground continuity. One version of the ground shield 20 can be mounted on a printed circuit board to which filter capacitors 40 are soldered.

Abstract: Electrical connectors (40, 104) including contact terminals that can be unmated without previously disconnecting power include main contacts (12, 112) and auxiliary contacts (16, 130) that are shunted by a positive temperature coefficient (PTC) resistor (6, 140) located between the main and auxiliary contact. The main contact (12, 112) will be disconnected first and the auxiliary contact (16, 130) can be longer than the main contact (12, 112). Arcing will not occur at the mating end of the main contact (12, 112), because the current will be shunted to the still connected longer auxiliary contact (16, 130). I2R heating will increase the resistance in the PTC resistor (6, 140), so when the auxiliary contact (16, 130) is disconnected, current will be below the arcing threshold.
