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 relates to a metering device for adjusting and/or controlling a gas flow, characterised in that the metering device comprises an electrically controllable valve, wherein the gas flow through the metering device can be adjusted and/or controlled by means of the electrically controllable valve, wherein the metering device has a pressure sensor, wherein a gas pressure difference across a gas-outlet opening in the metering device can be measured by means of the pressure sensor, wherein the electrically controllable valve can be adjusted according to the measured gas pressure difference; and/orwherein the metering device comprises an adjustable pressure-control device, wherein a maximum gas pressure difference between an inlet region of the metering device and an outlet region of the metering device can be set by means of the adjustable pressure-control device, wherein the gas flow through the metering device, which gas flow can be adjusted by means of the electrically controllable valve, is limited by the maximum gas pressure difference between the inlet region of the metering device and the outlet region of the metering device which is set by means of the adjustable pressure-control device.

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 and the formation of wand heads and wands. Specifically, the invention includes a nozzle having a tip portion, the tip portion having a stream shaper, and the stream shaper having at least four fins with a longitudinal dimension in the tip portion greater than a radial dimension in the tip portion.

A beverage dispenser includes a gas infusion device that receives a base fluid and a gas and dispenses a gas infused liquid, a ratio pump that receives the gas infused liquid and a concentrate from a concentrate source and dispenses a predetermined ratio of the gas infused liquid and the concentrate, and a mixing chamber that mixes the predetermined ratio of the gas infused liquid and the concentrate to form a reconstituted beverage. An insulated enclosure has an interior space in which the ratio pump and the mixing chamber are positioned. A cooling heat exchanger is positioned in the insulated enclosure, and a first refrigeration system circulates a cooling media through the cooling heat exchanger to thereby cool the interior space to a suitable temperature such that the gas infused liquid and the concentrate dispensed from the ratio pump and the mixing chamber are cooled to the suitable temperature.

Various systems, devices, and methods of venting a chamber in a beverage carbonation system are provided. A carbonation system is one example of a treatment system to which the systems, devices, and methods described herein apply. In general, a carbonation system can include a venting system configured to vent a mixing chamber of the carbonation system in which a carbonated fluid is configured to be formed. The venting system can be configured to provide flow restriction configured to provide a restriction on a vent flow path through which the mixing chamber is vented.

A system prepares and dispenses non gas-infused and gas-infused beverages including a gas source, a pressurizable container connected to the gas source to receive a first flow of gas, a gas infusion tank connected to the gas source to receive a second flow of gas, a first dispensing tap that receives a portion of preprocessed beverage stored in the pressurizable container that flows under pressure from a portion of the first flow of gas to dispense a non gas-infused beverage from the first dispensing tap, and a second dispensing tap that receives gas-infused beverage from the gas infusion vessel to dispense the gas-infused beverage by the second dispensing tap, the gas-infused tank receiving a portion of the preprocessed beverage from the pressurizable container to infuse the preprocessed beverage in the gas infusion vessel with at least a portion of the second flow of gas.

A method and dispensing apparatus for dispensing one or more liquids from a liquid storage container operably connected to the dispensing apparatus. The one or more liquids may include cold water, cold carbonated water, hot water and/or ambient temperature water. The dispensing apparatus preferably is a self-contained dispensing apparatus, i.e., a dispensing apparatus having its own source of liquid. The dispensing apparatus further preferably includes a housing storing a first cooled liquid reservoir and a second cooled liquid reservoir. The first cooled liquid reservoir preferably stores cold water and the second cooled liquid reservoir preferably stores cold carbonated water. A thermal link preferably connects the first cooled liquid reservoir and the second cooled liquid reservoir to cause thermal energy to be transferred between the first cooled liquid reservoir and the second cooled liquid reservoir.

Examples disclosed herein relate to conduits, devices, systems and methods, which may include a dispensing device including a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure; and a solenoid configured to interact with the outlet stream.

Drinks dispensing system (10) comprising a first syrup pump (20) being controllable to deliver a predetermined dose of syrup from a first syrup container (22) to a dispensing valve assembly (16), a second syrup pump (20) being controllable to deliver a predetermined dose of syrup from a second syrup container (22) to the dispensing valve assembly (16), a control system (200) configured to control the operation of the first and second syrup pumps (20) by setting a first electrical power parameter of electrical power to be supplied to drive the first syrup pump (20) independently of a second electrical power parameter of electrical power to be supplied to drive the second syrup pump (20); and a water delivery system (14) configured to deliver water to the dispensing valve assembly (16), wherein the dispensing valve assembly (16) is operable to mix and dispense syrup and water.
