A portable foam brush assembly having a base having a soap supply, a water supply, and an electrical supply. A foam brush wand is detachably dockable to the base and in electrical and fluid communication with the foam brush wand having battery pack, a peristaltic pump, a reservoir chamber, a foaming chamber, an air pump, a brush and a momentary release switch. The base water supply and the base soap supply, when activated, are configured to travel by a water supply hose and a soap supply hose to a tee in the base where they are combined in a combined hose to a base quick coupler that is connectable to a reciprocal foam brush wand quick coupler, which has a foam brush wand hose to deliver the water soap mixture to bladder in the foam brush wand.

A method as well as a liquid mixing system provide a liquid-foam mixture by mixing water with at least one additive. The liquid mixing system includes a water pressure source, an additive reservoir unit, an air compressor unit with a compressor and a drive device, a first and second mixing device, a discharging unit, and multiple different line networks for the respective media. The drive device is formed by a water engine or a water turbine, the water inlet of which is line-connected to the water pressure source.

A tray assembly for improved gas/liquid contact in a chemical process tower includes a tray deck and a downcomer. A mixer is provided in the top of the downcomer and a distributor is attached to a floor of the downcomer. The mixer includes at least one mixing baffle parallel to an outlet weir on the tray. The distributor includes a plurality of spaced apart flow directing plates extending downwardly toward and spaced apart from the floor of the downcomer. In combination, the mixer and distributor effect even liquid flow across the surface of a subjacent tray deck.

Systems, apparatuses, and methods for making content liquid foamy for discharge are described herein. A dispenser for making content liquid discharge foamy by mixing air flow from an air chamber with the content liquid flow from a liquid chamber can be provided. The dispenser can include a mixing chamber configured to mix air and content liquid; a porous member between an air passage from the air chamber and the mixing chamber; and a liquid passage from the liquid chamber to the mixing chamber. The liquid passage can have a first liquid passage and a plurality of second liquid passages. The liquid passage can be configured such that content liquid flows from the first liquid passage to the second liquid passages to the mixing chamber. The second liquid passages can be configured to provide flow of the content liquid in at least two directions.

A portable foam brush includes a soap reservoir, such as optionally in a base or in a wand, a foaming chamber, and an air compressor, such as optionally battery-operated air compressor. The compressor is configured for supplying air to act upon the soap from the reservoir to cause dispensing of soap to the foaming chamber. In some embodiments, the compressor may also supply air to the foaming chamber. In use, the soap and the air in the foaming chamber combine to form an air and soap foam. The brush includes a brush end configured for receiving foam from the foaming chamber and dispensing the foam.

Electrically operated coffee machine, in particular espresso machine or fully automatic coffee machine, having a steam output device that can include a steam lance wherein the steam lance can include a milk inflow which is configured to supply milk into a steam output channel of the steam lance.

Wands are used as parts of cleaning systems to conduct cleaning agents into gas turbine engine cores. Wands according to the present disclosure include inlet assemblies adapted to connect to cleaning agents, dispensers adapted to discharge cleaners into gas turbine engines, and conduits that extend from the inlet assemblies to the dispensers.

Method of designing and manufacturing a distributor bar for use in a production line comprising a mixing head for providing a viscous foamable liquid mixture, a laminator with a predefined speed of at least 20 m/min, the distributor bar having a central inlet fluidly connected to a number of outlets via a main channel. The method comprises: choosing (3001) a geometry for the distributor bar and defining a set of geometrical parameters; assigning (3002) values to said parameters; creating (3003) a virtual model; simulating (3005) flow in said model by performing a Computational Fluid Dynamics simulation (CFD), taking into account (3004) a non-Newtonian shear thinning model; e) evaluating the simulated flow; building (2007) a physical distributor bar. A distributor bar, a production line, and a computer program product.
