Abstract: A remotely controllable apparatus, system and method for monitoring, inventory, controlling and reporting on the filling, refilling and dispensing of Liquified Natural Gas (LNG) at portable temporary or semi-permanent field-located storage and dispensing stations, including a portable storage tank, and an associated portable pump and control skid, which skid includes: an on-site microprocessor control system having: security features; pump, fill and dispense connections; an LNG leak detection system; a communications link (typically an RF cellular phone system) to a host computer; a dispensing and refilling sales authorization and initiation system (typically a card reader of the credit, access or proximity card types); and a remotely located host computer having a full suite of features including: inventory, monitoring, security and access control; operational control; financial and transaction record keeping and report generation; and emergency warning and shut-down.

Abstract: A cartridge soft feed mechanism for presenting the cartridge to the chamber of a gun in such a way that the axis of the cartridge experiences no lateral or angular movement during chambering. The cartridge is telescoped into the chamber without ramping, reducing the probability of damage to the cartridge and reducing the chance of a chambering stoppage. The barrel is moved to a position and at such an angle during chambering that the cartridge is moved directly forward into the chamber, and then the barrel with the cartridge is moved into alignment with the moveable bolt for firing.
