Abstract: A plug for a void in a mine to divert water having a rigid closed cell foam which fills the void. The rigid closed cell foam having a plurality of pipes disposed within the foam. The pipes distributed throughout the void. The pipes are positioned in the foam so the pipes are staggered in length vertically with respect to various heights in the void, and the pipes are positioned in the foam every 4? to 6? horizontally with respect to the void. Each pipe has a mixing stick. A method for diverting water from a void in a mine.

Abstract: A weapon is capable of firing cased telescoped (CT) ammunition rounds. The weapon includes a barrel, a chamber member that defines a chamber configured to hold a CT round for firing from the weapon, a non-rotating carrier body, and linkage. The linkage is constructed and arranged to move the chamber member (i) from a firing position in which the chamber member is aligned with the barrel for firing the CT round to an ejection/loading position in which the chamber member is not aligned with the barrel for ejecting a spent CT round and receiving a next CT round in response to the non-rotating carrier body moving away from the barrel, and (ii) from the ejection/loading position to the firing position in response to the non-rotating carrier body moving toward the barrel.

Abstract: Devices and methods are provided for using an identity-aware proxy to filter transmissions for virtual networks. The device may receive an encrypted application programming interface (API) call from a second device, wherein the encrypted API call is associated with a remote network resource, and wherein the device is included in a remote network which includes the remote network resource. The device may determine, based on the encrypted API call, an account associated with the remote network resource. The device may determine that the account is not authorized to access the remote network resource using the remote network. The device may send an error notification to the second device.

Abstract: A firearm for firing cased telescoped (CT) ammunition cartridges that includes a split chamber configured to fully support a CT cartridge when it is fired, and that includes i) a dynamic rear chamber portion defining a pocket in a face of a bolt, and ii) a static front chamber portion that is integral to the barrel and separate from the bolt. A cartridge extraction mechanism engages the CT cartridge prior to the CT cartridge being fired, and holds the CT cartridge in the pocket in the bolt face as the bolt moves rearward to pull the CT cartridge out of the static front chamber portion and into an ejection position. An ejector is operable to eject the CT cartridge from the pocket in the face of the bolt when the CT cartridge reaches the ejection position.

Abstract: A weapon for firing cased telescoped (CT) ammunition includes a barrel, a chamber member and a carrier assembly. The chamber member defines a chamber for a CT round for firing, and translates between a firing position aligned with the barrel and an ejection/loading position. The chamber member is spring-biased toward the firing position. Dual-feed structure provides for both a magazine mode as well as a belt feed mode of operation.

Abstract: A magazine for storing cased telescoped (CT) cartridges and delivering the CT cartridges to a firearm configured to fire CT cartridges. The magazine includes a fixed lip and a moveable lip. The fixed lip and the moveable lip of the magazine are configured to prevent a CT cartridge located in a top-most position within the magazine from being pushed out a top of the magazine when the magazine is not fully inserted into a magazine well of the firearm configured to fire CT cartridges. The moveable lip may pivot laterally on a pivot point and move out of the way of the CT cartridge located in the top-most position within the magazine when the magazine is fully inserted and locked into the magazine well of the firearm configured to fire CT cartridges.

Abstract: Embodiments provide for an impact force gauge that includes a track and a shell that is designed to flex from a first state to a second state when a force exceeding a predetermined threshold is applied along a given axis and that is designed to return to the first state when the force falls below the predetermined threshold along the given axis. A roller is located in the shell and has a diameter such the roller is allowed or blocked from moving to different locations in the impact force gauge based on the force applied thereto. Based on the presence or absence of the roller along different portions of the track, the force gauge wirelessly transmits an indication of whether the force gauge has been exposed to a force that exceeds the predetermined threshold.
