  • Patent number: 11925912
    Abstract: The disclosure features a system that includes a plurality of material tanks, each of which includes at least one material for forming a chemical composition and includes a first recirculation loop; at least one mixing tank in which the materials from the material tanks are mixed to form a chemical composition, the mixing tank including a second recirculation loop; and at least one holding tank configured to continuously receive the chemical composition from the mixing tank, the holding tank including a third recirculation loop. The system may further include a plurality of fluid flow controller units and be configured to form material and chemical composition flows in an in-process steady state.

  • Publication number: 20190105620
    Abstract: This disclosure features methods of forming chemical compositions. The method includes (1) mixing a plurality of continuous material flows in a mixing tank to form a chemical composition, each continuous material flow including at least one component of the composition; and (2) moving a continuous flow of the chemical composition to a packaging station downstream of the mixing tank. The mixing and moving steps are performed continuously. This disclosure also features systems that can be used to perform such methods.

  • Patent number: 9419878
    Abstract: A network controller for delay measurement in SDN and related delay measurement system and delay measurement method are provided. A probe packet is used to record the transmission of the probe packet between the network controller and network switches, to calculate a transport delay time between the network switches and hop delay time between the network switches, to obtain the delay of each link in the transmission path, which helps in finding out a critical hop in the SDN transmission path. Through the delay measurement mechanism according to the present disclosure, the critical hop will become a reference based on which a network manager adjusts a network framework, or a basis taken by an SDN control system to select a path.
