A scraping tip is attached to a blow gun. The scraping tip includes a neck and a head attached to the neck. The neck is hollow cylindrical and centered about a main longitudinal axis. The head has an internal cavity, a first angled face, a second angled face, a first nozzle, and a second nozzle. The internal cavity is in gaseous communication with an interior of the neck. The first angled face is in a first angled plane, while the second angled face is in a second angled plane. The first nozzle is hollow cylindrical, centered about a first longitudinal axis, merges with the internal cavity, and terminates in the first angled face. The second nozzle is hollow cylindrical, centered about a second longitudinal axis, merges with the internal cavity, and terminates in the second angled face. The scraping tip allows focused high velocity air to aid with scraping.

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 semiconductor process system includes a semiconductor process chamber having an interior volume. A pump extracts gases from the semiconductor process chamber via an outlet channel communicably coupled to the semiconductor process chamber. The system includes a plurality of fluid nozzles configured to prevent the backflow of particles from the outlet channel to interior volume by generating a fluid barrier within the outlet channel responsive to the pump ceasing to function.

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.

An air nozzle includes a main body having a compressed air passageway to allow a compressed air to flow therethrough and a compensation air passageway in communication with the compressed air passageway. An external air is sucked into the compressed air passageway through the compensation air passageway and ejected together with the compressed air when the compressed air flows through the compressed air passageway.

An attachment for an air blow gun includes a nozzle and a nozzle insert. The nozzle is a hollow cylinder and includes radial pinholes at one end. The nozzle insert includes a longitudinal pinhole. The nozzle insert is inserted into the end of the nozzle with the radial pinholes. When high-pressure air is delivered to the attachment, plumes of high-velocity air exit from the radial pinholes and the longitudinal pinhole. The attachment is particularly well suited to cleaning confined spaces in workpieces with high-velocity air.
