A sprinkler assembly includes a connection fitting and a fire protection sprinkler. The connection fitting includes a tubular member with a first insertion end and a second insertion end with an internal conduit extending between the first and second insertion end along a longitudinal axis, the tubular member including an exterior surface and an inner surface, the inner surface defining a sealing surface between the first and second insertion ends circumscribed about the longitudinal axis and including a gripping portion axially spaced from the sealing surface. The fire protection sprinkler has a body defining an inlet and an outlet, a deflector spaced from the outlet, the body having an outer encasing surface surrounding the longitudinal axis and including a leading portion and a trailing portion for insertion in the second insertion end with the leading portion received within the sealing surface before the trailing portion engages the gripping portion.

A sprinkler guard includes at least one plate centered relative to a central axis of the sprinkler guard. A plurality of legs includes first and second legs that are attached to one plate, and third and fourth legs that are attached to another plate. A circular ring is attached to lower ends of the first to fourth legs, a center of the circular ring coinciding with the central axis, and the first to fourth legs being spaced apart about the circumference of the circular ring. First and second arms are attached to the first and second legs, respectively. In addition, a cross bar can be attached to the circular ring and extend across a diameter of the circular ring.

A system for biological decontamination uses high velocity low pressure emitters to create a fog of liquid decontamination agent or liquid and gaseous decontamination agents to blanket a volume to be decontaminated. The liquid decontamination agent and atomizing gas are suppled under pressure to the emitters which create various shock fronts in the gas stream as the gas is discharged from the emitters. The liquid decontamination agent is entrained in the gas stream as it is also discharged from the emitter, and the shock fronts atomize the liquid decontamination agent into droplets which form the decontaminating fog.

A ball joint connector is provided for linking a showerhead to a water supply pipe. The connector has an internal venturi that draws air into the connector to aerate water being provided to the showerhead. A flow control member is disposed in a fluid pathway connected to the venturi, preventing spraying or leaking out the air inlet, while reducing noise associated with the air induction.

A modular liquid distribution system in which each module has a module body, a spray nozzle, and a cyclically operable piston for controlling the dispensing of high viscous liquids from the spray nozzle. Each spray nozzle has a nozzle body with a liquid inlet and a tear dropped shaped pintle which together with the nozzle body defines an expansion chamber that reduces velocity of the liquid sufficient to be dispensed in small droplet form without splattering. In one embodiment, the nozzle body has a discharge orifice sized smaller than the outer diameter of the expansion chamber for accelerating liquid flow upon discharge sufficient to enhance consistent and repeatable breaks in the cyclically controlled fluid flow stream for enabling the discharge of smaller and more consistent volumes.

The invention relates mainly to an above-ground farming module which includes an element for supporting plants defining a root chamber for the aerial portion of the plants, and which includes means for forming a mist of nutritional solution (9) and means (25, 26) for circulating said mist of nutritional solution (30) located in the root chamber (4). The means for forming the mist of nutritional solution (9) advantageously include an ultrasound mister (10) located in the bottom of a misting cell (9) on which at least one opening for propagating the nutritional mist (20) in the root chamber (4) is arranged, and the means (25, 26) for circulating the mist of nutritional solution (30) are located next to said opening (20).

A fluid mixing device that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

An aerosolization device for an aerosol wetting chamber comprising a receiving opening for receiving the aerosolization device and adapted for wetting samples disposed in the aerosol wetting chamber with aerosol, the aerosolization device comprising a main body, an aerosol deflector and a swirling device.

A sprinkler assembly including an outlet frame defining a sprinkler longitudinal axis and an outlet with a pair of frame arms defining a first plane. A deflector is coupled to the frame arms with the deflector having an upper surface and a lower surface orthogonal to the longitudinal sprinkler axis. The deflector includes a plurality of tines defining a plurality of slots between the tines. The tines include a terminal portion having a terminal edge. A first symmetric tine is aligned with the pair of frame arms with the first symmetric tine being symmetric about the first plane and a second symmetric tine is symmetric about a second plane perpendicular to the first plane. A pair of asymmetric tines is disposed about and adjacent the first symmetric tine with the terminal edge of the first symmetric tine closer to the second plane than the terminal edges of the asymmetric tines.
