An inert gas distribution system nozzle 1 including an inlet 10 to receive fluid from a fluid supply, a chamber 32 to receive the fluid from the inlet and dimensioned relative to the inlet to permit the fluid to expand to form a mist, and at least one passage 34 to receive the fluid from the chamber and dimensioned relative to the chamber to promote condensing of the mist, wherein the, or each, passage comprises an outlet 40 to emit the fluid from the nozzle. A cross-sectional area of the passage is less than a cross-sectional area of the chamber.

A spray tip including a spray tip body and flow control element is provided. The flow control element includes a pre-orifice through which fluid can enter a primary fluid passage of the spray tip body. First and second discharge orifices are provided in a dome-shaped end wall of the spray tip body with each of the first and second discharge orifices being arranged on a respective one of opposing first and second sides of an apex of the dome-shaped end wall. Each of the first and second discharge orifices having an elongated slot-like configuration that maintains a substantially constant width as the respective discharge orifice extends from a first end to a second end and each and each extending a substantially equal distance to either side of the apex of the dome-shaped end wall.

A rotating sprinkler for irrigation is disclosed. The sprinkler can include a turret and a stream conditioner positioned in the turret. The stream conditioner can include a plurality of fins forming a plurality of flow regions. One or more of the plurality of flow regions can have a cross-sectional flow area that decreases in a downstream direction towards the primary port so as to accelerate the pressurized water through the stream conditioner. The plurality of fins can further straighten the water.

The invention provides a device (100) for applying a liquid film to surfaces in an area. The device (100) comprises a head (110) for discharging a flow of liquid droplets (200) in a discharge direction (D). The device (100) is arranged for rotating the head (110) according to two rotational degrees of freedom to move the discharge direction (D) through the area. The device (100) comprises a distance sensor (120) for measuring a distance (d) between the head (110) and surfaces in the area along the discharge direction (D). The device (100) is configured according to at least one of a first and second configuration. In the first configuration a rotational speed of the head (110) is adjustable as a function of the distance (d) measured by the distance sensor (120). In the second configuration a flow rate of the flow of liquid droplets from the head (110) is adjustable as a function of the distance (d) measured by the distance sensor (120).

A rectifying member capable of improving a collision force of a jet fluid, and a nozzle. A rectifying member includes rectifying elements each having a tubular casing and a division wall structure formed in the casing; the division wall structure includes partition walls, and has a circumferential division wall group being adjacent in a circumferential direction of an inner wall of the casing and having an extending partition wall, and an inside division wall group in an inside region of the fluid flow path.

A concentrator nozzle attachment for a blower device is disclosed that increases the airflow velocity of the blower without sacrificing the field of the jetting air. The concentrator nozzle is formed of an outer ring with a centrally located guide surface and is placed at the exit of an air tube. As the air exits the air tube, it's forced to flow around the guide surface, thus increasing its velocity. The attachment is secured to the end of the air tube and so does not alter the outer diameter through which the air exits. In this way, air velocity is increased without reducing its effectiveness.

An above-ground swimming pool is provided. The pool includes a bottom surface with side walls extending upwardly therefrom to define an inner volume for receiving water. The pool further includes top edge portions mounted on a top perimeter of the side walls and caps mounted between adjacent top edge portions. The pool also includes at least one water module adapted to connect to and operate with the above-ground swimming pool. The water module has a module base connectable to the top perimeter of the side wall of the swimming pool, a module casing extending upward from the module base and having a distal opening; and a supply system provided within the module casing and having a discharge opening for supplying water out of the supply system and through the distal opening of the module casing to enter an inner volume of the above-ground swimming pool.

A method and apparatus for generating a wave in a body of water may include altering a flow of water as it is urged through an inlet, contoured passage, and outlet. For example, a primary flow of water may be altered so that one or more secondary flows are created at angles to the direction of primary flow.

Disclosed herein are systems and methods for treating the surface of a microelectronic substrate, and in particular, relate to an apparatus and method for scanning the microelectronic substrate through a cryogenic fluid mixture used to treat an exposed surface of the microelectronic substrate. In particular, an improved nozzle design used to expand the fluid mixture is disclosed herein. In one embodiment, the nozzle design incorporates a two nozzle pieces are combined to form a single nozzle design, in which the two pieces are slight misaligned to form a unique orifice design. In another embodiment, two pieces are combined and aligned along a common axis of the fluid conduit. However, an offset piece is inserted between the two pieces and has a hole that misaligned from the flow conduits of the two other pieces.
