Abstract: A composite article includes a first segment and a second segment spaced apart form the first segment. The composite article includes continuous fibers that extend from the first segment to the second segment. The composite article also includes discontinuous fiber distributed throughout the composite article.

Abstract: To provide a trusted, secure, and immutable record of transactions within a process plant, techniques are described for utilizing a distributed ledger in process control systems. The distributed ledger may be maintained by nodes which receive transactions broadcasted from field devices, controllers, operator workstations, or other devices operating within the process plant. The transactions may include process plant data, such as process parameter data, product parameter data, configuration data, user interaction data, maintenance data, commissioning data, plant network data, and product tracking data. The distributed ledgers may also be utilized to execute smart contracts to allow machines such as field devices to transact by themselves without human intervention. In this manner, recorded process parameter values and product parameter values may be retrieved to verify the quality of products.

Abstract: Devices and applications within a process control system make data generated therein available using a really simple syndication (RSS) XML communication format, thereby making this data easily retrievable from the plant and useable for various purposes both within and outside of the plant. The RSS data communications may provide RSS data for use in control of the plant or for use in other applications not directly associated with the control of the plant, including third party applications run on devices outside of the plant. The RSS data sent from one device to another may include enclosures, such as video, audio or text files, or may include references such as hyperlinks to other sources of information stored on the receiving device or on a further device that may be accessed and used to understand or process the RSS data.

Abstract: A process control system within a process plant and, in particular, different devices and applications within the process control system such as field devices, controllers, user interfaces, alarm applications, diagnostics applications, etc. create, store and make data generated therein available using a really simple syndication (RSS) XML communication format, thereby making this data easily retrievable from the plant and useable for various purposes both within and outside of the plant. The RSS data communications may provide RSS data for use in control of the plant or for use in other applications not directly associated with the control of the plant, including third party applications run on devices outside of the plant, such as personal data assistants, pagers, phones, laptop computers, etc.

Abstract: Methods and apparatus to create process plant operator interfaces are disclosed. A disclosed example method to create a process plant operator interface comprises receiving a search criterion, identifying a user interface module based on the search criterion, and adding the identified user interface module to the process plant operator interface.
