  • Publication number: 20230196431
    Abstract: A computer-based system is provided for processing information associated with industrial tool solutions. The system may include a digital platform for executing the tasks of various functional modules that provide a virtual toolbox within the platform. In one aspect, a solutions module receives information associated with multiple configurations of different industrial tool solutions, and displays graphical representations associated with each of the industrial tool solutions. A machines module is programmed for receiving information associated with machines associated with use of the industrial tool solutions, and also can display a digital replica of each machine. A project module is programmed for receiving and displaying project information including the industrial tool solution information and machine information.

  • Patent number: 11566718
    Abstract: Valves and valve assemblies are described herein employing architectures which can mitigate degradative wear mechanisms, thereby prolonging life of the assembly. In one aspect, a valve comprises a head including a circumferential surface and a valve seat mating surface comprising sintered cemented carbide. Leg members extend from the head, wherein thickness of one or more of the leg members tapers in a direction away from the head to induce laminar fluid flow around the head. In some embodiments, the sintered cemented carbide is an inlay coupled to the valve head.

  • Patent number: 11318480
    Abstract: In one aspect, centrifuge feed pipes are described herein having design and architecture for mitigating wear during centrifuging operations. In some embodiments, a centrifuge feed pipe comprises a feed material inlet, a feed material outlet, and a conduit body extending along an axis between the feed material inlet and outlet, the conduit body having a variable inner diameter at one or more locations along the axis. In being variable, the inner diameter is not uniform over all radial positions of the inner diameter.

In one aspect, a valve comprises a head including a circumferential surface and a valve seat mating surface. Leg members extend from the head, wherein thickness of one or more of the leg members tapers in a direction away from the head to induce laminar fluid flow around the head. The valve can also comprise a seal coupled to the circumferential surface of the head. In some embodiments, an exterior surface of the seal exhibits a radius of curvature maintaining laminar fluid flow around the valve. Additionally, the seal can overlap a portion of the valve seat mating surface, in some embodiments.
