Abstract:
An air-conductive rotary sprinkler includes an air-conductive rotary sprinkling device and an air/fluid supply assembly. The air-conductive rotary sprinkling device further includes a main housing tube, an inner rotary tube and a rotary spray head. The rotary spray head includes a spray-head casing connected with the inner rotary tube and a guide plug installed inside the spray-head casing and further including a helical actuating groove, a helical conductive groove, a central channel and a sideway channel. The fluid in the fluid-conveying pipe can be sprayed along the base axis by the pressured airflow from the central channel, the rotary spray head is rotated by the pressured airflow from the helical air channel, the spray direction of the fluid originally flowing along the base axis is altered by the pressured airflow from the helical conductive channel so as to spray out of the rotary spray head in a rotary manner.

Abstract:
An aerosol is produced by flowing a liquid sample through a gas-assisted nebulizer. The liquid exits from an outlet into a coaxial flow of gas. The outlet includes a sharp edge that inhibits or prevents accumulation of precipitates from the liquid, thereby reducing or eliminating clogging, which is particularly useful for a samples containing high concentrations of dissolved particles. The aerosol may be introduced into a plasma such that molecules are broken into atoms. The atomization may be followed by an analysis such as by optical emission spectrometry or mass spectrometry.
Abstract:
A micronozzle device can include at least one layer having a plurality of nozzle exits for delivering a mixture of a first fluid and a second fluid, at least one first-fluid header layer having a plurality of first microchannels for receiving the first fluid, at least one first-fluid via layer adjacent the at least one first-fluid header layer to receive the first fluid and direct it to respective ones of the plurality of nozzle exits, at least one second-fluid header layer having a plurality of second microchannels for receiving the second fluid, at least one second-fluid via layer adjacent the at least one second-fluid header layer to receive the second fluid and direct it respective ones of the plurality of nozzle exits, and a plurality of first curtain-gas nozzles located at a first side of the micronozzle device and a plurality of second curtain-gas nozzles located at a second side of the micronozzle device.
Abstract:
A surface treatment system including a pressure generator structured to generate air pressure, a spray head assembly coupled to the pressure generator, the spray head assembly including a trigger that can be depressed to control an amount of air pressure that the spray head assembly uses to spray the surface treatment material and a bushing disposed behind the trigger and being structured to limit an amount the trigger can be depressed, and a hopper coupled to the spray head assembly and structured to hold surface treatment material, wherein the hopper is configured to provide the surface treatment material to the spray head assembly and the spray head assembly is configured to use the air pressure to spray the surface treatment material onto a surface.
Abstract:
A speaker and assemblies with a speaker. An assembly may include a speaker including a speaker housing, and speaker components supported in the speaker housing and operable to produce an audio output; a sensor operable to sense an orientation of the speaker housing; and control components operable to determine the orientation of the speaker housing, and control the speaker components based on the orientation of the speaker housing.
Abstract:
A prosthetic heart valve includes a base and a plurality of polymeric leaflets. Each leaflet has a root portion coupled to the base, and each leaflet has an edge portion substantially opposite the root portion and movable relative to the root portion to coapt with a respective edge portion of at least one of the other leaflets of the plurality of leaflets. Each leaflet includes) at least two polymers along at least one portion of the leaflet, and each leaflet has a composition gradient of each of the at least two polymers along at least one portion of the leaflet.
Abstract:
The application sets forth a knapsack or backpack spraying device having a blower unit and a spraying medium container fixed to a carrying frame. The blower unit conveys an air stream through a blower pipe. Spraying medium is fed from the spraying medium container to the air stream. The spraying medium container has a filling opening which is closed by a cover. The cover has a lower edge facing the spraying medium container. The spraying device has a standing position in which it stands on a flat, horizontal standing face and in which the cover is arranged on an upper side of the spraying medium container facing away from the standing face. To reliably avoid contact of the operator with spraying medium, the height of the carrying frame, measured at right angles to the standing face, is at least 80% of the overall height of the spraying device.
Abstract:
A spray nozzle for two-component flue gas cleaning nozzles. The spray nozzle includes an output or mixing chamber and at least two through bores which lead to the output or mixing chamber and are each connected to a fluid line. At least one through bore is embodied in such a way that it is self-cleaning and/or a cleaning device is provided for at least one through bore.
Abstract:
A liquid atomization device includes a nozzle body. The nozzle body includes: a first gas spray portion and a second gas spray portion for spraying two gas flows; a liquid passage having a passage through which liquid flows by formation of the two gas flows sprayed by the first gas spray portion and the second gas spray portion; a gas-liquid mixture area where the gas flow sprayed from the first gas spray portion and the gas flow sprayed from the second gas spray portion are made to collide against liquid which flows from the liquid passage to atomize the liquid; and a spray outlet for spraying mist atomized in the gas-liquid mixture area to outside.
