Abstract: A lifter bar for a grinding mill includes an elongate structural support defining a longitudinal axis and extending from (i) a first end transverse to the longitudinal axis to (ii) a second end transverse to the longitudinal axis; a plurality of structural plates extending along the longitudinal axis in spaced relation, where each structural plate is transverse to the longitudinal axis, and defines opposed edges. The lifter bar may further include at least two protective plate portions, each protective plate portion being mounted over one set of the opposed edges.

Abstract: Systems, methods, and computer-readable storage media are provided for provisioning a common subnet across a number of subscribers and their respective virtual networks using dynamically generated network policies that provide isolation between the subscribers. The dynamic generation of the network policies is performed when a host (e.g. client) is detected (via a switch) as the host joins the computing network via virtual networks. This ability to configure a common subnet for all the subscriber virtual networks allows these subscribers to more easily access external shared services coming from a headquarter site while keeping the separation and segmentation of multiple subscriber virtual networks within a single subnet. This allows the Enterprise fabric to be more simple and convenient to deploy without making security compromises.

Abstract: Techniques for communication network routing include receiving, at a routing device associated with a first site in an overlay communication network, a dynamic parameter value associated with each of a plurality of additional sites in the overlay communication network. The plurality of additional sites are each configured to provide a first network service for a computing device in the first site. A second site in the overlay communication network is selected, from among the plurality of additional sites, based on a first dynamic parameter value associated with the first site and a received second dynamic parameter value associated with the second site. The first network service is provided from the second site for the computing device, based on the selecting the second site.

Abstract: A check valve assembly includes a first flapper, a second flapper, an internal passage formed by the first flapper and the second flapper, and a nozzle disposed within the internal passage and configured to generate an internal flow in the internal passage. In response to a fluid flow through the check valve assembly, the first flapper and the second flapper are configured to move between an open position allowing the internal flow through the internal passage and an outer flow outside the internal passage, and a closed position preventing flow through the internal passage. When the first flapper and the second flapper are operably in the open position, the internal flow has a lower pressure than the outer flow outside of the internal passage, such that the first flapper and the second flapper are maintained in the open position.

Abstract: Techniques for network routing border convergence are described. Backup paths for external connections for a network are established and provide for a temporary path for network traffic during network routing convergence, preventing traffic loss at network border nodes.

Abstract: A mapping system, under administrative control of a Wide Area Network (WAN) controller, can track each host, authorized to access a plurality of Local Area Networks (LANs), in one or more mapping databases including a first network address representing an identifier and a second network addressing representing a locator for each host. The mapping system can receive a request for resolution of a first identifier of a host not presently connected to the network. The mapping system can determine the mapping databases exclude a mapping for the first identifier. The mapping system can update the mapping databases with a first mapping including the first identifier and a first locator corresponding to a honeypot network device. The mapping system can transmit, to one or more LANs of the plurality of LANs, routing information to route traffic destined for the first identifier to the honeypot network device.

Abstract: Systems, methods, and computer-readable media for implementing an extranet policy include receiving a request from a source to perform a lookup for a destination address. A lookup for the destination address is performed in a consolidated routing table, the consolidated routing table including a consolidated mapping of address prefixes associated with two or more virtual networks. If the lookup results in a match for the destination address with a matching address prefix, a matching virtual network associated with the matching address prefix is determined. An access policy for the request corresponding to the matching virtual network is obtained, and based on the access policy the request is allowed to access the destination address in the matching virtual network or disallowed. The consolidated routing table can be implemented in a mapping server using a Locator/ID Separation Protocol (LISP).

Abstract: A fuel oxygen reduction unit for an engine is provided. The fuel oxygen reduction unit includes a contactor including a fuel inlet that receives an inlet fuel flow and a stripping gas inlet that receives an inlet stripping gas flow, the contactor configured to form a fuel/gas mixture; a separator that receives the fuel/gas mixture, the fuel oxygen reduction unit defining a circulation gas flowpath from the separator to the contactor; and a level control device that controls a level of the fuel/gas mixture inside the separator by regulating the inlet fuel flow to the contactor.

Abstract: Systems and methods for network authorization are described herein. An example method can include receiving a user credential from a host device connected to a network, authenticating the user credential, and in response to authenticating the user credential, determining an authorization policy associated with the host device. The method can also include polling a network overlay control plane of the network to obtain a network location information associated with the host device, identifying at least one network device of the network using the network location information, and transmitting the authorization policy to the at least one network device.

Abstract: This technology enables normalized lookup and forwarding for diverse virtual private networks in multi-site network fabric deployments. A source device on a first Layer 2 site transmits a frame to a destination device on the same subnet, but on a second Layer 2 site. The frame is encapsulated and routed to a fabric border node. The fabric border node matches the source subnet to the destination subnet and transmits an address request protocol (“ARP”). In response to not receiving a reply to the ARP, the fabric border node transmits a map request to a Layer 3 transit fabric control plane node. The control plane node extracts a destination identifier from the map request and determines that the destination identifier is a Layer 2 identifier. The control plane node transmits a map reply to the fabric border node, where the frame is re-encapsulated and forwarded to the destination device.
