A mobile CO2 filling system selectively fills onsite CO2 storage and dispensing systems with CO2. The system includes a mobile platform; a tank holding liquid CO2 mounted on the mobile platform; a flexible dispensing hose couple to the tank and configured to be selectively coupled to the filling inlet of an onsite CO2 storage and dispensing system; a pump selectively coupled to the tank; and a controller for controlling the filling of an onsite CO2 storage and dispensing systems with CO2 from the tank, wherein the controller is selectively designated by the user to operate in at least one pump assisted filling state and at least one gravity feed filling state.

An in-stock compressed fluid cartridge system to be used in a gas powered airsoft gun. The compressed fluid cartridge may be supplied fluid to a multi-stage expansion chamber configured to depressurize the fluid into gas and prevent fluid from reaching a downstream pressure regulator. The compressed fluid cartridge may be engaged and disengaged with the in-stock system by turning a thread-less quick release end cap that allows rapid replacement of the cartridges.

A cold energy power generation system increases the efficiency in utilizing the cold exergy of liquefied gas while freely controlling the gas supply pressure on the outlet side of a secondary expansion turbine. The system includes a pressure-increasing pump for increasing the pressure of a low-temperature liquefied gas to a pre-overboost pressure while maintaining the liquid gas in a liquid state, a Rankine-cycle-type primary power generation apparatus, a heater for heating a vaporized gas, and a direct-expansion-type secondary power generation apparatus. Since the cold exergy of the liquefied gas is more efficiently utilized as pressure exergy than as temperature exergy, the system converts the cold exergy more preferentially to pressure exergy, and the optimal operating conditions that maximize the conversion efficiency can be determined by the composition of the liquefied gas, the temperature of the heating source, and the gas supply pressure.

This invention discloses an inflator mechanism for rafts and life vests that performs a multitude of functions required for rescue and underwater deployment of personnel and devices. The inner cylinder in this disclosure is actuated by a plethoria of inputs, manual, automatic selectable pressure sensing, or dualled hydrostatic sensors which can each be safely selected by function selection. Since the inflator uses spring discs to drive a penetrator which mechanically punctures a membrane of an inflation gas source and actuated by an electronically controlled solenoid, dissolvable elements, conductivity switches and preset check valve actuators are eliminated increasing the safety and reliability of the actuator. Electronic control further permits user enabling of inflation depth actuation and the multiple water sensors prevent failure of actuation due to splashes and humidity effects on sensors. The actuator mechanism is self cocking, indicates proper installation of gas source enables use of several gas source cylinders and is multiply reusable.

An offload system is provided. The offload system is configured to offload a target species stored in an onboard volume positioned onboard a vehicle to an offboard volume. In one aspect, the offload system includes an onboard system positioned onboard the vehicle and an offboard system positioned offboard the vehicle. The onboard system selectively allows the target species stored in the onboard volume to flow downstream to the offboard system, which includes the offboard volume. The onboard system, the offboard system, or both, include features that facilitate efficient and safe offloading of the target species from the onboard volume to the offboard volume.

Provided herein is a system and method for refilling refillable pressurized fluid tanks. The system includes a source tank, having a source fluid, a target refillable tank, a valve assembly, and a fill hose. The valve assembly is affixed to the refillable fluid tank and is fluidly attached to the source fluid tank with the fill hose. The fluid from the source fluid tank is transferred to the target refillable fluid tank via the fill hose and the valve assembly. When the target refillable fluid tank is filled to capacity, excess propane is dispensed from the valve assembly through an overfill valve.
