Fixed systems and method for extinguishing large scale industrial tank fires, with and without fixed roofs, and featuring aerated foam projecting nozzles and including fixed center directed nozzles.

The invention includes components and methodology for fixed and semi-fixed systems for extinguishing fire in large industrial flammable liquid storage tanks, including aerated foam projecting nozzles discharging substantially focused streams together with aeration chambers and risers.

A system and method to supply nitrogen gas is provided. Ambient air is compressed and stored in a storage receiver and then nitrogen is separated from the compressed air in a nitrogen membrane separation unit. The separated nitrogen is stored in a nitrogen storage tank under pressure and released through a pressure control valve. The system is confined to a small footprint and is useful as a nitrogen source where conventional compressed nitrogen tanks are a safety or space issue. Systems to prepare nitrogen infused beverages are also provided.

The invention relates to a method for drawing a carbonated drink from a dispenser system, in which the carbonated drink is conducted via a line through a flow controller and a filter that is downstream of said flow controller. The invention also relates to a dispenser system and to a cartridge unit comprising a filter.

In certain examples, a beverage dispenser includes a gas system configured to collect ambient air, pressurize the ambient air, and dispense the pressurized ambient air, a valve configured to dispense a base fluid, and a concentrate system configured to dispense a concentrate. A manifold is configured to form a gas-injected mixed beverage comprising the base fluid, the concentrate, and the pressurized ambient air, and a nozzle is configured to apply a back-pressure upstream on the gas-injected mixed beverage and dispense the gas-injected mixed beverage.

Disclosed are exemplary embodiments of apparatus, systems and methods relating to transfer of fluids to/from containers and/or storage/transport of fluids in containers. In an exemplary embodiment, an apparatus comprises a container including a fitment having an opening. The apparatus may include a valve within the fitment. The valve may be configured to inhibit fluid flow out of the container. The apparatus may also include a transfer tube configured to be positioned through the opening of the fitment. The transfer tube may engage and open the valve to thereby provide an open passage to/from the container.

A system for dispensing a beverage from a pressurized beverage container, the system including an interface having a housing, a tap assembly, a dip tube, a carry handle, and a receiving section. The housing is configured to fasten to a neck portion of a beverage container. The tap assembly rigidly extends from the housing and has a tap handle and a passageway configured to allow a beverage to pass through the tap assembly and out a dispensing end of the tap assembly when the tap handle is activated. The dip tube extends from a first side of the housing and is coupled to the passageway of the tap assembly. The carry handle extends from the housing. The receiving section is configured to receive a pressure regulator and includes an opening extending from a second side of the housing through the first side of the housing.

Systems for filling and dispensing free-flowing contents into and out of a container, the container comprising: a top and a bottom, a plurality of vertical walls extending between the bottom and the top, an ice portal disposed in the top, the ice portal having a removable cap for filling an ice chamber with ice, a removable container cap, a tube vertically disposed in the container cap, the tube extending between a beverage bag and a gate valve above the container cap, an air hose disposed in the container cap parallel with the tube, an air bag attached to a bottom end of the air hose, the air bag being adjacent to the beverage bag, such that a volume between the bags and an interior of the plurality of vertical walls is the ice chamber, and a beverage flow portal protruding longitudinally from a side of the gate valve.

A liquid storage apparatus including a container, an upper cover, a dispensing faucet, a conduit, a gas cylinder and a gas cylinder sleeve. The container includes a cavity and an upper opening. The upper cover is arranged on the upper opening. The dispensing faucet is led out from a side of the upper cover and is connected to the conduit in the upper cover; and the conduit extends to a bottom of the container. The upper cover includes an adjusting knob, and a pressure of the cavity of the container is adjusted by rotating to open or close a valve of the gas cylinder. The pressure in the container can be adjusted since the gas cylinder is arranged in the container and the valve of the gas cylinder can be opened or closed by rotating the adjustment knob.
