The invention relates to an ultrasonic testing device and to a method for nondestructively testing a component, in particular a fiber-plastic composite component, having: an ultrasonic testing head; and a liquid nozzle with a liquid inlet, a liquid outlet, and an inner surface which tapers towards the liquid outlet, wherein the liquid nozzle has at least one liquid guiding rib which protrudes inwards into the sound chamber from the tapering inner surface of the liquid nozzle upstream of the ultrasonic testing head.

A showerhead includes a flow device and a flow distribution member. The flow device is configured to produce a substantially laminar fluid stream. The flow distribution member is coupled to the flow device and is spaced apart from the flow device. The flow distribution member is configured to receive the substantially laminar fluid stream from the flow device and to produce a distributed fluid flow.

An insert securable to the end of a hose is disclosed, the insert primarily intended to improve flow of a fluid emerging from the hose. The insert includes a generally cylindrical body portion, said body portion comprising an internal helical channel, the axis of said helical channel being offset from the insert axis, and conveniently parallel thereto.

In embodiments, an adjustable nozzle includes a nozzle body having an inlet section with an inlet opening, an outlet section with an outlet opening, and a fluid flow path extending from the inlet opening to the outlet opening; an adjustable spray restrictor segment located in the outlet section; and an actuator that displaces the adjustable spray restrictor segment toward and away from a center of the fluid flow path, thereby varying an effective width of the outlet opening to vary a pattern of fluid flowing from the fluid flow path through the outlet opening.

Provided is a liquid droplet discharging apparatus that can maintain stable discharging even when a liquid containing particles or cells adheres to a nozzle surface.

A spraying apparatus includes a spraying apparatus main body, a liquid introduction portion, a gas introduction portion, a gas-liquid spout portion, a liquid inlet, a gas inlet, a tubular flow passage, a spout, a flow passage having a taper, a straightener, and a projection portion. The liquid inlet allows a liquid flow to enter a gas-liquid mixer which is a space inside the annular gas introduction portion. The gas inlet allows a gas flow to enter the gas-liquid mixer. The straightener has an opening having an uneven shape provided in the flow passage having the taper. The projection portion is provided in the liquid introduction portion, protrudes to the gas-liquid mixer, and forms the straightener and a straightening outlet.

A spray head for a power sprayer configured to generate a continuous sheet-like water shield around a center stream of water is disclosed. A water delivery device for use with a sink is disclosed, the water delivery device may produce a stream of water surrounded by a continuous shield of water.

A sanitary unit (1, 116, 118) is provided which has a sleeve-shaped outlet mouthpiece (2), which (2) can be installed on a water outlet of a sanitary outlet fitting and has a sleeve interior, into which is inserted a sanitary functional unit (5) with at least one functional element (5), which (5) has a component (6), which (6) can be adjusted between at least two functional positions, by an externally accessible handle, via a transmission element (9) which is guided in an axially displaceable manner in the functional element (5). The handle is configured in the form of an actuating element (7) which is retained in a displaceable manner on the outer circumference of a sub-region, forming part of the outlet mouthpiece (2), which projects beyond the water outlet of the outlet fitting, and the actuating element (7), which serves as a handle has a water-jet-permeable or water-jet-guiding outlet structure (8) held on it that connects the actuating element (7) to the transmission element (9).

The inventive concept relates to a liquid dispensing nozzle and an apparatus for treating a substrate. The liquid dispensing nozzle includes a first fluid channel that is formed in the nozzle and through which a processing liquid flows and a second fluid channel in communication with the first fluid channel, the second fluid channel being connected to a dispensing end of the nozzle. The second fluid channel has a larger width than the first fluid channel, and a central axis of the first fluid channel and a central axis of the second fluid channel are connected with each other in a straight line.
