A nozzle includes a mounting part that is configured to be attached to a blower, and a body part that is connected to the mounting part. The body part has a discharge opening and a passage for air blown out by the blower. The passage leads to the discharge opening. The body part includes a flexible tube. The flexible tube has a length of at least 15 cm and defines at least a portion of the passage.

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.

The systems and methods provided herein are directed to a stationary device for simulating the periodic unsteadiness typically produced by turbines in an air stream. A streamlined body includes a line of jets along its leading edge that pulses air at an angle against the air stream, and a separate line of jets along its trailing edge to expel a sustained air flow in the same direction as the air stream.

Provided is an apparatus for cooling a metal material, the apparatus comprising: a spray cooling unit for spraying a cooling medium onto the surface of a metal material; and a spray amount control unit which regulates the rate of passage of the cooling medium sprayed from the spray cooling unit onto the edge region of the metal material, and controls the spray amount of the cooling medium.

An air amplifier utilizes a high-pressure input stream of air to accelerate a low-velocity input stream of air to provide a high-velocity, high-volume output stream of air. A coupled air amplifier array includes multiple air amplifiers which couple their respective output streams of air to one another to form a single collective output stream of air. Multiple coupled air amplifier arrays can be utilized to form coupled air amplifier array systems to provide multiple collective output streams of air which can be focused toward to an audience within a venue. The coupled air amplifier array system can be implemented within atmospheric effects systems to provide atmospheric effects, such as wind, scent, and/or temperature to provide some examples, relating to an event. These atmospheric effects systems can present these atmospheric effects to the audience to enhance the immersion of the audience as they are viewing the event. These atmospheric effects systems can include multiple portable mobile effects pods that are situated within different locations within the venue to present these atmospheric effects to different locations with the venue.

A hand-held sealing device may be used for sealing a tubeless tire on a corresponding wheel rim. The wheel rim may have a valve stem hole to receive a valve stem. The hand-held sealing device may include a device body. The device body may include an air output nozzle, a directed air outlet defined in the air output nozzle, and an air inlet defined in the device body. The air inlet may be fluidly communicated with the directed air outlet. The hand-held sealing device may also include a valve assembly disposed between the directed air outlet and the air inlet. A cable may be slidably disposed in the air output nozzle. The cable may pass through the directed air outlet. A valve stem engagement member may be configured to removably attach to the valve stem. The valve stem engagement member may be connected to the cable.

A high-speed nano mist is a group of liquid droplets having a particle diameter of 1 nm to 10000 nm and flying at a speed of 50 m/s to 1000 m/s.

A sensor apparatus includes a sensor window; a first nozzle adjacent to the sensor window and oriented to blow across the sensor window, the first nozzle positioned below the sensor window and in a first horizontal direction away from the sensor window, the first nozzle being slot-shaped with a first length and a first thickness; and a second nozzle adjacent to the first nozzle and oriented to blow across the sensor window, the second nozzle positioned below the sensor window and in the first horizontal direction away from the sensor window, the second nozzle being slot-shaped with a second length and a second thickness. The second nozzle is farther from the sensor window in the first horizontal direction than the first nozzle, and the first length of the first nozzle is greater than the second length of the second nozzle.

A foreign matter removal device (1) is configured to remove foreign matters on a lens (101) of an in-vehicle camera (100) attached to a vehicle so that the lens (101) of the in-vehicle camera (100) is exposed toward an outside of a body panel of the vehicle. The foreign matter removal device includes a single-cylinder type reciprocating pump (5) configured to generate high-pressure air and a nozzle (22) configured to inject the high-pressure air toward the lens (101). A volume of an internal space of the pump is 10 cm.sup.3 or less. Exhaust time (t1) per cycle required for exhausting the air in the internal space is 0.03 seconds or less.
