Methods and apparatus are disclosed for a coupling nozzle for cryogenic fluid. An example nozzle comprises a flow body defining a conduit, an inlet, and an outlet. A pneumatic cylinder is configured to slide between an extended position and a contracted position. The pneumatic cylinder is coupled to and configured to actuate the flow body. A locking mechanism is configured to secure the coupling nozzle to a receptacle. A flow control assembly comprises a valve seat fixed to the flow body adjacent the inlet and a plug configured to slide. When the locking mechanism is locked and the pneumatic cylinder actuates to the extended position, the valve seat is to disengage from the plug to open the flow control assembly. When the locking mechanism is locked and the pneumatic cylinder actuates to the contracted position, the valve seat is to engage the plug to close the flow control assembly.

Disclosed herein is a gas-liquid mixing and distributing device. The gas-liquid mixing and distributing device includes a mixing head including a chamber, a plurality of gas spray nozzles, and a plurality of liquid spray nozzles; and a liquid supplying part connected to the mixing head and supplying a liquid to the mixing head, wherein the plurality of gas spray nozzles and the plurality of liquid spray nozzles included in the mixing head are uniformly mixed and distributed so that the liquid and gas sprayed from the mixing head are uniformly mixed with each other.

The invention relates to a component of a gaseous fire suppression system. A concealed extendable nozzle for gaseous fire suppression systems is mounted on a distribution pipe of a gaseous fire suppression system. The nozzle consists of a body with discharge openings and a cap. A rod of a nipple is mounted inside the body of the nozzle. The nipple rod has a variable outside diameter: at one end, the rod narrows and ends in a connecting thread, whereas at the other end, the rod widens. Meanwhile, the body has an opening of variable diameter, which permits movement of the nipple rod inside the body; the body of the nozzle has a widening on the outside. A cap is fastened to the body of the nozzle, and this connection is tightly sealed by a washer. The technical result is the even dispersal of a gaseous fire extinguishant inside a room.

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 cleaning device is provided. The cleaning device comprises a hollow, hand-held wand that accepts pressurized gas at a first end and forces the gas out a second end, a trigger mechanism that features a coupling for acceptance of gas from a hose positioned at the first end, and a diffuser attached perpendicularly to the second end to receive and release the pressurized gas, the diffuser disposed to turn in a spinning motion, whereby ends of the diffuser are angled and feature one slit opening per end, and whereby the angled ends facilitate the spinning motion by the diffuser.

In a compressed-fluid discharge control device, there are formed a valve chamber communicated with a discharge channel and supply channels for supplying a compressed fluid, and a pilot chamber into which the compressed fluid is introduced from the supply channels. A diaphragm valve for communicating or cutting off communication of the supply channels and the discharge channel seats on or separates from a valve seat provided in the valve chamber. Pilot channels through which a compressed fluid supplied to the pilot chamber passes are formed in the diaphragm valve. The compressed-fluid discharge control device has a pilot chamber opening/closing valve for opening or closing the pilot chamber. The pilot chamber opening/closing valve includes a solenoid valve which is opened in response to energization thereof and closed in response to de-energization thereof.

The invention provides a telescoping wand assembly for use in dispensing liquid from a container, including a trigger module extending along a longitudinal axis between proximal and distal ends. The trigger module includes a tubular handle member, a user accessible trigger positioned externally of the tubular handle member that is selectively movable between first and second positions, a hose positioned within the tubular handle member and adapted to transport liquid from the container, and a valve actuating member that is selectively, movably actuable by movement of the trigger between its first and second positions. A stationary frame assembly provides rigidity and contact points for a telescopically movable tube assembly that extends from the trigger module. A shut-off valve and nozzle are positioned at the distal end of the wand assembly and movement of the shut-off valve is controlled by the trigger and translated by way of the tube assembly.

Embodiments of showerheads having a detachable gas distribution plate are provided herein. In some embodiments, a showerhead for use in a semiconductor processing chamber may include a body having a first side and a second side; a gas distribution plate disposed proximate the second side of the body and having an annular channel formed in a side surface; and a clamp disposed about a peripheral edge of the gas distribution plate to removably couple the gas distribution plate to the body, wherein the clamp includes a body and a protrusion extending radially inward into the annular groove, and wherein a portion of the gas distribution plate extends over a bottom surface of the clamp.

A compressed gas ejection assembly 10 for a rotating wing aircraft blade 2 comprises a compressed gas passage 114 adapted to allow a substantially constant mass flow through the compressed gas ejection assembly 10 across at least a portion of the width of the compressed gas ejection assembly 10.
