Abstract: Certain embodiments of the present application relate to a variable frequency drive (VFD) cabin for a pump configuration including a mobile trailer on which the VFD cabin is to be mounted. The VFD cabin generally includes a medium-voltage VFD and a ventilation system. In certain embodiments, the ventilation system is configured to generate an overpressure condition within the cabin to discourage the entry of dust and debris into the cabin. In certain embodiments, one or more components of the medium-voltage VFD are coupled to the floor of the cabin via a vibration damping system. In certain embodiments, the VFD cabin may be directly coupled to a chassis of the mobile trailer without an intervening suspension being provided between the VFD cabin and the chassis.

Abstract: An electric driven hydraulic fracking system is disclosed. A pump configuration includes the single VFD, the single shaft electric motor, and the single hydraulic pump mounted on the single pump trailer. A controller associated with the single VFD and is mounted on the single pump trailer. The controller monitors operation parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether the operation parameters deviate beyond a corresponding operation parameter threshold. Each of the operation parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system. The controller initiates corrected actions when each operation parameter deviates beyond the corresponding operation threshold.

An example of pavement material includes a pervious concrete material. The method includes providing a quantity of pavement material and adding a quantity of cured carbon fiber composite material to the pavement material to produce a reinforced composition having improved characteristics.

Abstract: An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A pump configuration includes a single VFD configuration, the single shaft electric motor, and the single shaft hydraulic pump mounted on the single pump trailer. The single VFD configuration converts the electric power at the power generation voltage level distributed from the power distribution trailer to a VFD voltage level and drives the single shaft electric motor to control the operation of the single shaft electric motor and the single hydraulic pump. The VFD voltage level is a voltage level that is required to drive the single shaft electric motor. The VFD configuration also controls operation of the auxiliary systems based on the electric power at the auxiliary voltage level.

Abstract: This invention relates to heterogeneous catalysts useful for selective hydrogenation of unsaturated hydrocarbons, comprising palladium and optionally a promoter, supported on a substrate, having an uncoated BET surface area of ?9 m2/g, the surface being coated with an ionic liquid. Also described are methods of making the catalysts and methods of selective hydrogenation of acetylene and/or dienes in front-end mixed olefin feed streams.

Abstract: A system and method of event ticketing utilizing an article dispensing machine is disclosed. A ticket order transaction related to an event is managed at an article dispensing machine by presenting a series of simple and easy to understand interface pages on a user interface. A user interacts with the interface pages to make decisions on aspects of the ticket order transaction. A listing of events available for ticket ordering on the article dispensing machine is curated by reviewing prospective events. The listing is curated based on the location of the article dispensing machine, the priority ranking of the event, the date and time of the productions, the category of the events, the location of the venue relative to the article dispensing machine, and/or other factors. A hyper-local listing of events can be presented so that the events that are most likely relevant to users.

Abstract: A system and method of dynamically generating ticket barcodes for ticket orders is disclosed. A ticket order including tickets related to an event may be received from an article dispensing machine or another source. Random barcodes can be generated as the basis for the ticket barcodes. The ticket barcodes can be generated based on barcode attributes unique to a ticket supplier or a venue of the event. Such barcode attributes can include a barcode prefix, a barcode suffix, a barcode total length, and a barcode symbology. When the tickets in a ticket order are ready to be produced, images of the ticket barcodes can be generated and assigned based on the barcode attributes. The user experience for purchasing tickets from disparate ticket suppliers and/or venues can accordingly be simplified and streamlined.
