Abstract: A vehicle cargo lift includes a stationary slide adapted to be mounted on a roof of a vehicle. The cargo lift is automatically extended to a position for easily loading cargo onto the lift and is automatically retractable to a position on top of the vehicle roof. A rolling slide is slidably mounted to the stationary slide and a rear tray is movably supported by the rolling slide. A front tray is supported by the rear tray via a pair of elbow arm assemblies that are extendable below the rear tray.

Abstract: Embodiments of a multi-port multi-mode valve are provided. The multi-port multi-plane valve includes a housing which defines an internal cavity. The housing further includes a plurality of ports, including two inlet ports and four outlet ports. Each of the plurality of ports is in communication with the internal cavity. A shell body is rotatably disposed within the internal cavity and provides selectable fluid communications between the ports. A seal member is also provided which has a plurality of openings and surrounds the shell body. Six modes of operation are provided by rotation of the shell body.

Abstract: A system for mixing fluids includes at least two pressurized containers, a batching hopper in fluid communication with at least one of the at least two pressurized containers, a mixer in fluid communication with the batching hopper, and a fluid line in fluid communication with the mixer. An automated method of mixing fluids includes measuring a property of a fluid in a rig fluid system, transferring contents from a rig storage container to a batching hopper, transferring the contents from the batching hopper to a mixer, determining an amount of contents to add to a flow of the fluid in the rig fluid system based on the measured property, and mixing the determined amount of contents in the mixer with the flow of fluid from the rig fluid system.
