Abstract: Arrangements for dynamic generation of interactive mapping interfaces are provided. Transaction data may be received by a computing platform and analyzed to extract user and location information for each transaction. The computing platform may generate, based on the extracted user and location data, an interactive mapping interface providing a visual display of transactions within a geographic area. The interactive mapping interface may include a plurality of interactive icons that identify a physical location of a transaction. The interactive mapping interface may be transmitted to a user computing device for display by a display of the user computing device. The computing platform may receive user input associated with user interaction with one of the interactive icons and may generate and transmit, to the user computing device for display, an additional user interface that may include transaction details and a selectable option to report the respective transaction as fraudulent.

Abstract: Arrangements for dynamic generation of interactive fraud mapping interfaces are provided. In some examples, fraud reporting data may be received by a computing platform. The fraud reporting data may include incidents of potentially fraudulent activity reported by a plurality of users. If at least a threshold volume of fraud reporting data is received, the fraud reporting data may be analyzed using a machine learning engine. For instance, the fraud reporting data may be input to the machine learning engine to output one or more compromised or potentially compromised payment terminals, vendor or retail locations, or the like. In some examples, the computing platform may generate an interactive fraud mapping interface that includes an interactive icon associated with each compromised location of the one or more compromised locations. The interactive fraud mapping interface may be transmitted or sent to a user computing device for display.

Abstract: An air distributor for carbon black reactor in which the air is brought radially inwardly toward the reactor axis is disclosed in which the incoming air is diverted in an upstream direction and flowed around the end of and into a tubular member to achieve distribution.

Abstract: A generally cylindrical carbon black reactor for the production of soft carbon blacks is modified to produce a wider range of products by the installation of a choke.

Abstract: A rotary combustion engine having a planetary rotor and side intake ports is provided with an apex seal arrangement comprising two side-by-side seal members providing spaced sealing lines of contact at each rotor apex and wherein communicating grooves in the ends of the two apex seal members and existing corner seals connect the space between the apex seal members to the existing spaces between the side seals and oil seals on the rotor sides which periodically communicate with the side intake ports.

Abstract: A multi-apex rotary combustion engine rotor has simplified side face circular compression seals mounted in circular grooves passing across the face of corner button seals. The button seals are of a substantially enlarged diameter permitting machining of the circular seal grooves in the rotor side face.
