  • Valves, valve assemblies and applications thereof
    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.
    Type: Grant
    Filed: April 4, 2019
    Date of Patent: January 31, 2023

  • Centrifuge feed pipes and associated apparatus
    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.
