Abstract: A pressure vessel disclosed herein comprises a chamber. The pressure vessel also comprises a passageway extending from an exterior wall of the pressure vessel to the chamber. A one-way valve is disposed in the passageway. The one-way valve is normally closed and is in fluid communication with the chamber. A plug is disposed within the passageway and is accessible from outside of the pressure vessel.

Abstract: An excavation apparatus includes a supporting linkage mountable to a vehicle, and a rotary spindle operable to drive a coring element about a cutting axis. The supporting linkage supports the rotary spindle and is operable to displace the rotary spindle relative to a ground surface. The supporting linkage can lower the rotary spindle to a deployed position and raise the rotary spindle to a stored position. The cutting axis can be maintained in a vertical direction in the deployed and stored positions. The rotary spindle can move relative to the supporting linkage about a hinge axis. The hinge axis can be generally parallel to the vertical direction.

Abstract: Techniques are described by which a routing protocol, such as border gateway protocol (BGP), is extended to control propagation and importation of information using route targets (RTs) specified as bitmasks that encode link administrative group information. For example, a network control device (e.g., controller) is configured to allocate one or more subset of resources (e.g., nodes or links) of an underlay network to each of one or more virtual networks established over the underlay network. The controller generates a bitmask encoded with link administrative group information of the one or more links. The controller then outputs, to a plurality of provider edge (PE) routers that are participating in a respective virtual network, a routing protocol message to advertise the one or more subset of resources, wherein the routing protocol message includes a route target specified as the bitmask.

Abstract: In general, techniques are described for dynamically controlling host-bound traffic by dynamically adding and updating, within the forwarding plane of a network device, network packet policers that each constrains, for one or more packet flows, an amount of host-bound traffic of the packet flows permitted to reach the control plane in accordance with available resources. In one example, a control plane of the network device detects internal congestion in the communication path from the forwarding plane to control plane (the “host-bound path”), identifies packet flows utilizing an excessive amount of host-bound path resources, computes limits for the identified packet flows, and adds “penalty-box policers” configured with the computed limits for the identified packet flows to the forwarding plane. The forwarding plane subsequently applies the policers to the identified packet flows to constrain the amount of traffic of the packet flows allowed to reach the control plane to the computed limits.
