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.

A heating apparatus includes a heating element (48) which converts electrical power to heat energy, a heatable element (44) having a first surface and a second surface, and a dielectric laminate layer (46) between the heating element and the first surface of the heatable element, wherein the dielectric laminate layer (46) is thermally conductive to transfer heat energy from the heating element (48) to the heatable element (44), and wherein the second surface of the heatable element is configured heat a liquid in a container.

A mixer (19), for an exhaust system (7) for mixing and/or evaporating a liquid (13) in an exhaust gas flow (8), especially for an SCR system (9), includes a plurality of guide blades (21) arranged in a star-shaped pattern. Simplified manufacturability of the mixer (19) is achieved if the guide blades (21) are connected each with a centrally arranged core (23) radially on the inside and if the guide blades (21). The guide blades (21) and the core (23) are formed by an integral cast part (24).

Embodiments of a process for treating a fluid are provided. The process for treating a fluid includes supplying a first fluid to a circulating chamber and introducing a first gas to the first fluid. A portion of the first gas is dissolved in the first fluid and a portion of the first gas is held in a head space portion of the circulating chamber. The process further includes mixing a portion of the first fluid drawn out from the circulating chamber and a portion of the first gas drawn out from the head space portion to form a mixture. The process further includes spraying the mixture back into the circulating chamber by a two-fluid nozzle. In addition, the first gas is further dissolved into the first fluid to form a high conductivity fluid. The process further includes draining the high conductivity fluid from the circulating chamber.

The invented system used in wet cooling tower, restore outlet fog of cooling tower into collection basin and consequently cooling water cycle. This invention consists of three main components; pump and its pertaining piping, waterfall and micron fog eliminator. In the first stage, the air containing fog is passed through a waterfall before exhausting. This action causes some portions of fog to condensate and fall down, remaining droplets of the fog grow and together with air cross the fog eliminator blades. Fog's droplets are entrapped between blades, leave the air, and restore to the tower. Therefore, humidity of exhausted air from tower will be effectively reduced.

An aeration cabinet is provided. The aeration cabinet secures a compressor within. The aeration cabinet includes a bottom portion operable to support the aeration cabinet in an upright position when resting on a surface. The bottom portion may include a base plate. The present invention further includes a front wall, a rear wall, a first side wall and a second side wall extending vertically from the horizontal base plate. A lid covers an opening formed along an upper edge of the front wall, the rear wall, the first side wall and the second side wall. A plurality of first vent slots are formed through the aeration cabinet where the front wall and the base plate meet. A plurality of second vent slots are formed through the aeration cabinet where the lid and the rear wall meet.

A substrate processing system includes a chemical liquid preparation unit preparing a chemical liquid to be supplied to a substrate and a processing unit which supplies the chemical liquid, prepared by the chemical liquid preparation unit, to the substrate. The chemical liquid preparation unit supplies an oxygen-containing gas, containing oxygen gas, to a TMAH-containing chemical liquid, containing TMAH (tetramethylammonium hydroxide), to make the oxygen-containing gas dissolve in the TMAH-containing chemical liquid.

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.

A static mixing module for mixing of material includes an inlet end and an outlet end, between which a longitudinal axis extends. A plurality of angularly spaced mixing channels extendingbetween the inlet end and the outlet end, each two adjacent mixing channels being separated by an intermediate wall. At least one mixing element is provided within each mixing channel. Each intermediate wall has a uniform or an essentially uniform wall thickness (t) as measured in a plane perpendicular to the longitudinal axis. A steam heater is also disclosed which comprises said static mixing module.

The present invention discloses a system for introducing a gas into a contained media such as a pond or lake. Water is removed from the media, gas introduced, and then the water removed to the contained media.
