The invention relates to an improvement in nozzles/screen for fluid flow distribution/collection used In fluid flow distribution/collection used In fluid processing units. Improvement in conventions nozzle/screen comprises a flow restricting cylindrical body to have ring washer shape aperture control at inlet/outlet. The improved nozzle/screen comprises outer casing made of stacked flat rings with micro opening between said stacked ring providing uniform throughout its periphery. A central conduit having holes for flow of fluid entering through the said outer casing. The said conduit having means to regulate fluid flow.

A nozzle head and an apparatus for subjecting a surface of a substrate to successive surface reactions of at least two precursors according to the principles of atomic layer deposition, the nozzle head includes a nozzle head body, a nozzle head output face and gas channels for transporting gas. The nozzle head further includes a first through hole through at least two of the two or more nozzles and a first tube having a tube wall and being fitted into the first through hole, said first tube including gas conduits provided in the tube wall for providing a fluid communication between the first tube and the gas channels in connection with the two or more nozzles.

A nozzle device for sorting objects by ejecting a gaseous media towards said object. The nozzle device nozzle device including: a nozzle unit including at least one nozzle; a nozzle bar including gas supply means for providing a gaseous media to said nozzle unit; and a nozzle fixation bracket adapted for holding said nozzle unit in place; said at least one nozzle including: an inlet for receiving the gaseous media; and having one outlet, having an outlet area, for ejecting the gaseous media towards an object to be sorted; a channel extending between said inlet and said outlet; an outlet portion surrounding at least said outlet, wherein said outlet portion includes a flexible material, which deflects upon ejection of the gaseous media, received from said nozzle bar, through said outlet whereby said outlet area increases. Also, a system for sorting objects.

A blow-off ring for cleaning components of an electric motor includes a first ring element and a second ring element, where the first ring element and the second ring element can be assembled in order to enclose an annular cavity within the blow-off ring. The first ring element and/or the second ring element has nozzles which are connected to the annular cavity and which extend along an inner circumferential surface and/or an outer circumferential surface of the blow-off ring.

A nozzle attachment and method for its use is provided. The nozzle attachment can be affixed to a fluid outlet. The nozzle attachment is constructed and arranged to increase the total output flow, flux, of the fluid outlet by using the high velocity directional fluid flow from the outlet to create a pressure differential between the flow and the surrounding medium, thereby causing fluid particles from the surrounding medium to be drawn into the fluid flow. The nozzle attachment comprises a nozzle attachment fixation element, a funnel element, and a frame connector extending between the nozzle attachment fixation element and the funnel element. The nozzle attachment has many applications and uses.

The present disclosure discloses an electric dust blower which includes a shell, a control panel, a battery module, a fan, an illumination lamp, and air outlet nozzles, where the shell includes two half shells capable of being spliced together left and right; the battery module is disposed at a lower portion of a mounting chamber; the fan is disposed at a rear portion of an air chamber and is close to an air inlet; the illumination lamp is mounted in a mounting hole and exposed out of a front end face of a main body; and the air outlet nozzles are detachably mounted at and connected to an air outlet.

A nozzle device for sorting objects by ejecting a gaseous media towards said object. The nozzle device nozzle device including: a nozzle unit including at least one nozzle; a nozzle bar including gas supply means for providing a gaseous media to said nozzle unit; and a nozzle fixation bracket adapted for holding said nozzle unit in place; said at least one nozzle including: an inlet for receiving the gaseous media; and having one outlet, having an outlet area, for ejecting the gaseous media towards an object to be sorted; a channel extending between said inlet and said outlet; an outlet portion surrounding at least said outlet, wherein said outlet portion includes a flexible material, which deflects upon ejection of the gaseous media, received from said nozzle bar, through said outlet whereby said outlet area increases. Also, a system for sorting objects.

A valve for providing pulses of aseptic air to a web of packaging material is provided. The valve comprises a rotatable valve shaft having an inlet portion with a circular cross-section, wherein the inlet portion is provided with a radial slot being connected to an axial cavity of the valve shaft. The valve further comprises a valve member comprising a curved end being adapted to fit with an exterior surface of the inlet portion of the valve shaft during rotation of the valve shaft, and a fluid channel extending through the valve member such that when the valve shaft is rotated to a position where the radial slot of the inlet portion is aligned with the fluid channel of the valve member, air can flow through the valve via the valve member and the valve shaft.

There is provided an exhaust nozzle unit capable of discharging a gas atmosphere in a substrate storage container having a loading/unloading opening from the container to an outside of the container through a port formed on a bottom surface of the container. The exhausted nozzle includes a nozzle capable of switching the port from a closed state to an open state by pressing a valve of the port; and a housing configured to hold the nozzle so as to be movable up and down between a use posture in which the port is in the open state and a standby posture in which the port is in the closed state.

Multiple single plenum and dual plenum showerhead designs are disclosed. In the designs, pillars are disposed in each plenum to increase solidity of the plenums to provide improved axial heat conduction through the showerheads. The heat conduction is further improved by providing solid and substantially conical backplates.
