Abstract: A cloud-based diagnosis and maintenance system facilitates discovery and indexing of plant-wide data residing on various data platforms across multiple industrial facilities. The system includes an indexing system that automatically inventories industrial devices and other data sources located throughout the facilities, and identifies available data items on each data source. The indexing system indexes the discovered data items in a federated data model that can subsequently be searched to locate data items or tags of interest. The diagnosis and maintenance system also includes analysis tools that facilitate cross-facility analysis of the data model, allowing performance metrics to be compared across similar automation systems at different facilities. The system can also generate recommendations for improving performance metrics based on results of the comparative analysis.

Abstract: A pistol has a frame with a striker operably connected to the frame. A trigger is operably connected to the frame. A transmission element is operably connected between the trigger and striker to motivate the striker to discharge the firearm in response to actuation of the trigger. The transmission element is movable between a first position in which operation connection from the trigger to the striker is enabled, and a second position in which operation connection from the trigger to the striker is disabled in response to acceleration forces due to dropping the pistol.

Abstract: An automated industrial notification platform creates a link between a given industrial asset and one or more people or support entities qualified to provide support for the asset. An industrial device or machine stores electronic expert tag information that records and catalogues one or more support people or entities to be notified in response to detection of various types of performance or maintenance issues. The tag can include the experts' identities, contact information, roles relative to the industrial asset, event priorities, and other relevant information. Since the tag is stored in a memory location of the industrial asset, the tag travels with the asset so that experts are globally associated with the asset regardless of the asset's location. Notification components integrated with the industrial asset detect conditions that may require expert assistance, and send an automated notification to one or more experts identified by the tag information.

Abstract: A multi-platform industrial search and notification system performs automated and manually initiate information searches across multiple disparate industrial data platforms. The search system is built on a search platform that unifies plant-wide control system information from multiple diverse sources under a common namespace, or federated data model. The system can monitor this federated data model for conditions that may warrant attention by plant personnel, and deliver proactive notifications and operational data to selected users via their personal devices. The system can customize presentation of this data based on the user's role, location, and/or other contextual information. To this end, the system can automatically generate user-specific and context-specific dashboards, widgets, or other visualizations, and render these custom visualizations to the user at appropriate times.

Abstract: A process for producing CMC articles that includes reducing the presence of porosity and voids within the articles. The process is performed on a porous fired preform comprising a fiber reinforcement material and a ceramic matrix material, and the preform is densified by heating the preform and a fill material to melt the fill material, and by creating a vacuum that causes the molten fill material to infiltrate and partially fill voids within the preform. While the fill material remains molten within the voids, the preform and fill material are subjected to an increased pressure to further fill the voids with the molten fill material. Thereafter, and while the preform and molten fill material therein remain subject to the increased pressure, the preform and fill material are cooled to solidify the fill material within the voids and yield a CMC article.

Abstract: A multi-platform industrial search system facilitates indexing and searching of plant-wide data residing on multiple different data platforms. The industrial search system automatically inventories industrial devices and other data sources located throughout a plant, and identifies available data items on each data source. The search system indexes the discovered data items in a federated data model that can subsequently be searched to locate data items or tags of interest. The federated data model records references to data items found on different types of data sources, including but not limited to industrial controller programs, human-machine interface applications, data historians, device documentation stores, inventory tracking systems, and other such data sources. The search system can present search results as a layered map presentation that graphically depicts the search results on multiple view-specific layers that can be viewed individually or combined into composite layered presentations.

Abstract: Various systems and apparatuses are provided for a turbulence member for an annular seal cavity in a fluid handling device. In one example, the turbulence member includes an inner face positioned to cooperate with a seal assembly in the annular seal cavity to define an inner channel. The turbulence member also includes an outer face positioned to cooperate with a housing to define an outer channel in the annular seal cavity. The turbulence member also includes a front face extending between the inner face and the outer face, and a rear face spaced from the front face and extending between the inner face and the outer face.

Abstract: A process for producing silicon-containing CMC articles. The process entails producing a matrix slurry composition that contains at least one resin binder and a SiC powder. The SiC powder is a precursor for a SiC matrix of the CMC article and the resin binder is a precursor for a carbon char of the matrix. A fiber reinforcement material is impregnated with the slurry composition to yield a preform, which is then heated to form a porous preform that contains the SiC matrix and porosity and to convert the resin binder to the carbon char that is present within the porosity. Melt infiltration of the porosity is then performed with molten silicon or a molten silicon-containing alloy to react the carbon char and form silicon carbide that at least partially fills the porosity within the porous preform. The carbon char constitutes essentially all of the elemental carbon in the porous preform.
