A system features a controller having a signal processor configured to: receive signaling containing information about a liquid level of a gas infused liquid in a liquid/gas infusion tank/vessel, one or more gas input characteristics of a gas provided to the liquid/gas infusion tank/vessel, and one or more liquid input characteristics of an incoming non-infused liquid provided to the liquid/gas infusion tank/vessel; and determine corresponding signaling containing information to control a pump that provides the incoming non-infused liquid to the infusion tank/vessel on demand each time a beverage is dispensed with the gas infused liquid from the liquid/gas infusion tank/vessel and to maintain a desired liquid level and target equilibrium gas pressure in the liquid/gas infusion tank/vessel at a given temperature.

Apparatus, and methods for constructing and implementing beverage containment and dispensing systems are provided herein. An example apparatus includes a thermally-insulated container, an adjustable pressure regulator positioned within the thermally-insulated container, a stopper component, and one or more tubes connected to the adjustable pressure regulator and to the stopper component. The example apparatus also includes an external housing within which the thermally-insulated container is contained, and a user-controllable faucet component affixed to the external housing and connected to the adjustable pressure regulator through the external housing and thermally-insulated container via at least one conduit.

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.

Disclosed are various embodiments for dispensing and tracking beverages. An identifier associated with a user can be read by an identification device. Beverage availability information for the user can be determined. The beverage availability information can specify categories of beverages that the user is authorized to dispense. Valves can be selected that correspond to the authorized beverage categories. The valves can be enabled to allow the user to dispense beverages from the authorized beverage categories. The quantity of beverages dispensed can be tracked.

Among other things, beverages are dispensed from one or more beverage dispensers based on selections made by users. Information about the dispensing of the beverages is sent to a central server where it is used to manage a variety of functions including replacement of depleted supplies of components. Various features of the beverage dispensers enable the beverages that are dispensed to be uniform and appealing to users.
