  • Patent number: 11148112
    Abstract: The present invention relates to different liquid distributors for monolith in multiphase applications. The present invention more particularly relates to distributor devices in the form of a single injection and multiple injection pipe distributors; shower head distributor comprising a plurality of holes for plunging liquid; a packing of spherical particles with a pre-distributor to split the liquid into manifold streams, before entry into the monolith bed. The present invention provides liquid distributors for monolith in multiphase applications providing improved liquid distribution into the monolith bed resulting in uniform fluid flow in each channel so as to make maximum use of the catalyst surface area.
    Type: Grant

  • Patent number: 9329904
    Abstract: Embodiments may enable cloud based computing infrastructure to automatically scale in response to changing service demands. Auto-scaling may be enabled by automatically provisioning computing resources as they may be needed by hosted computing services. Historical utilization patterns may be tracked enabling the generation of models that may be employed to predict future computing resource requirements. The automatic scaling system may comprise one or more models that may be trainable using business rules that may be applied to determine to if and how computing resources are scaled. Further, business rules may be arranged to determine provisioning and scaling of computing resources based in part on the historical usage patterns of the computing services.
