An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

The present invention relates to an aquarium pressurized gas vessel for supplying an aquarium (12) with CO2 gas generated in the aquarium pressurized gas vessel (10), wherein the aquarium pressurized gas vessel (10) comprises: a receiving vessel (14) for receiving a nutrient substrate and a reactant interacting with the nutrient substrate such that the nutrient substrate and the reactant react with each other to generate CO2 gas; a closing device (16) for closing the receiving vessel (14) in a pressure-tight manner; a gas outflow device (18) for extracting CO2 gas from the aquarium pressurized gas vessel (10) for the aquarium (12), wherein the CO2 gas has a gassing pressure (p_B) when flowing into the gas outflow device (18); a gas vessel pressure regulator (20) for adjusting a gas vessel pressure (p_G) which substantially corresponds to the gassing pressure (p_B).

Further, the present invention relates to a CO2 gassing system (28) comprising the aforementioned aquarium pressurized gas vessel (10).

Pressure vessels formed from fiber composites are described. The fiber composites include fibers impregnated with a resin system containing surface-modified nanoparticles dispersed in a curable matrix resin.

This invention relates to a novel method and system for dispensing CO2 vapor without over pressurization. The system includes one or more liquid containers and one or more vapor containers. The system is designed to operate in a specific manner whereby a restricted amount of CO2 liquid is permitted into the vapor container through a restrictive pathway that is created and maintained by a shuttle valve during the filling operation so that equalization of container pressures is achieved, thereby allowing shuttle valve to reseat when filling has stopped. During use, a pressure differential device is designed to specifically isolate the vapor container from the liquid container so as to preferentially deplete liquid CO2 from the vapor container and avoid over pressurization of the system until the vapor container. The system is operated so that at least 50% of the CO2 product is dispensed from the vapor container. The system also includes novel control methodology for performing pre-fill integrity checks to ensure safety of subsequent dispensing of CO2 liquid from a source vessel to the onsite CO2 containers.

This invention relates to a novel method and system for dispensing CO2 vapor without over pressurization from a system having multiple containers. The system includes one or more liquid containers and one or more vapor containers. The system is designed to operate in a specific manner whereby a restricted amount of CO2 liquid is permitted into the vapor container through a restrictive pathway that is created and maintained by a shuttle valve during the filling operation so that equalization of container pressures is achieved, thereby allowing shuttle valve to reseat when filling has stopped. During use, a pressure differential device is designed to specifically isolate the vapor container from the liquid container so as to preferentially deplete liquid CO2 from the vapor container and avoid over pressurization of the system until the vapor container becomes liquid dry. The system can be operated so that at least 50% of the CO2 vapor product is dispensed from the vapor container.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head

A home-based, low-cost, self-contained, fast-fill natural gas refueling station for providing compress natural gas (CNG) fuel for motor vehicles. The station compresses utility supplied natural gas and stores the CNG in a CNG storage facility located inside the station. In preferred embodiments the refueling station is located adjacent to a driveway at a home. The compressor preferably is a multi-stage gas compressor having at least three stages of compression. Applicant estimates that savings based today prices for CNG as compared to gasoline, a typical family with only one car could pay for the station in three years. If the family has several cars the station could pay for itself much earlier.

An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

A cartridge loader includes a lever arm, a hinge axle and a cam centered on the hinge axle, and a housing for receiving a cartridge, the housing having a first end and a second end, the first end adapted to connect to an appliance, and the second end adapted to allow the lever arm to open and close, the housing having an aperture exposing an interior of the housing, the aperture shaped to receive the cartridge and the lever arm, wherein the cam is adapted to assist in seating the cartridge in the housing when the lever arm is closed, and ejecting the cartridge when the lever arm is opened.
