An aerator including a faceplate for dispensing a first water stream, and a nozzle for dispensing a second water stream, the second water stream surrounded by the first water stream.

A sanitary insert unit is provided having a jet regulator which has a housing with a housing inlet and a housing outlet, and a jets splitter in the housing interior. The jet splitter protrudes partially into a diffuser ring, delimiting an annular channel therebetween. The diffuser ring is insertable into an outlet-side housing part of the housing until an annular step on the outer circumference of the diffuser ring bears on an inlet-side mating surface on an outlet-side housing part. A circumferential locking cam on an outer circumference of the diffuser ring is movable into locking engagement with a locking groove provided on an inner circumference of the outlet-side housing part. The locking cam has a run-on bevel which interacts with a mating bevel upstream from the locking groove in an insertion direction that has a greater angle of inclination with respect to a longitudinal axis in comparison with the run-on bevel.

A faucet for a water supply system for an aircraft includes a body portion having a water passage formed therein, and an adapter removably mounted to a discharge portion of the body portion, wherein the adapter is configured so that a mounting member is received within a casing, and the mounting member includes an orifice, a negative pressure forming chamber through which water having passed through the orifice flows, and an air passage hole communicated with the negative pressure forming chamber and mixing air taken in from an exterior of the adapter.

A jet regulator having a sleeve-shaped jet regulator housing which is assembleable on the water outlet of a sanitary outlet fitting, and having a wall which supports a perforated structure that forms the outlet end side of the jet regulator and which in the jet regulator housing is pivotable between a use position, in which the perforated structure extends transversely across an outflow-side sleeve opening of the jet regulator housing, and a cleaning position, in which the water flowing through the jet regulator housing can flow out on both sides of the wall through opening gaps formed between the wall and the neighboring housing internal circumferential wall. The wall has a spherical-layer-shaped external circumference and via which it is pivotably mounted in a joint socket provided on the housing internal circumferential wall of the jet regulator housing. A handling element extends from the wall and is latchable on the outflow-side housing end side of the jet regulator housing.

Provided is a UFB generating apparatus that is capable of efficiently generating a UFB-containing liquid with high purity by controlling generation of UFBs in the liquid. A UFB generating apparatus includes a driving unit that drives a heating element included in a heating unit to generate film boiling in the liquid in contact with the heating element, and a control unit that controls driving conditions of the heating element by the driving unit.

A method of manufacturing a metal component with an anti-microbial molecular layer may comprise: disposing the metal component in a piranha solution; washing the metal component; and grafting a surface of the metal component with a Si-Quat or hybrid Si-Quat molecular layer.
