Abstract: The present invention comprises a valve assembly with an unbalanced seal between sealing components of the valve assembly. For a gate valve assembly, an upstream seat may have a different outer diameter than a downstream seat, thereby creating an unbalanced seal with the gate. By increasing the sealing surface of the downstream gate/seat interface and by decreasing the sealing surface of the upstream gate/seat interface, the gate/seat interface may seal at lower pressures. A bidirectional seal is also disclosed that may prevent grease or sand from entering a cavity of the seat/pocket insert interface and assists with controlling the pressures and torque on the valve assembly.

Abstract: Methods and systems for limiting resource access based on user input using an authentication token. In some aspects, the authentication token receives user input indicating a first allocation for a first resource access to be executed at a first time. The authentication token generates recommendations for a second allocation related to the first allocation. The user selects a second allocation. At the first time, the authentication token receives a first resource access request and executes the first allocation. The authentication token also transmits first metadata to an access approval system. At the second time, in response to a second resource access request, the authentication token or the access approval system compares the second resource access request to the first metadata or the second allocation to approve or decline the second resource access request.

Abstract: A polymer cartridge includes an insert defining the base end and a body extending from the insert. The body forms a powder chamber which is in communication with a primer pocket formed in the insert via a flash hole formed through the insert top surface. A nose extends forward from the body and includes a shoulder that transitions into a neck defining a projectile aperture. An annular ridge is formed about the inner surface of the neck and positioned between the projectile aperture and the shoulder. The annular ridge is designed to engage the outer surface of a bullet that is the same caliber of the polymer cartridge. The bullet is designed with a groove corresponding to the location of the annular ridge so that the assembled cartridge is within the acceptable range for the total axial length thereof.
