Abstract: Nozzles for an air duct arrangement of an air conveying system may include a first outlet nozzle that is divided into a plurality of chambers are disclosed. The plurality of chambers formed by the outlet provide for a more uniform flow of air exiting the outlet, which generates a greater induced air flow in an associated section of duct. An orientation of a second outlet relative to an inlet of the nozzle provides for a reduced head loss within the nozzle, thereby providing for reduced backpressure within the nozzle and, consequently, a reduced power consumption associated with generating a desired airflow through the nozzle.

Abstract: Described herein is a bounce-reducing cover assembly that is positioned on the top of the cover and riser of a sprinkler to achieve a similar golf ball bounce characteristic as typical golf course turf. The cover assembly has a top surface that is composed of a plurality of vertical fingers or posts, which help achieve the desired bounce characteristics with a golf ball. Specifically, these fingers are flexible and provide some “give” so as to absorb some of the force from an incoming golf ball. Depending on the durometer of the material, size of the fingers, and spacing of the fingers, different bounce characteristics can be achieved.

Abstract: A method of fire suppression may include injecting a reactive agent into a reaction zone to produce a catalytically active species for fire suppression and conveying the catalytically active species to a fire to catalytically interfere with flame chemistry of the fire. Fire in a fuel tank may be suppressed by injecting the reactive agent into a convective flow of a mixture of fuel and oxidizer in a fuel tank, the reactive agent reacting in the fuel tank to release a species which catalytically interferes with flame chemistry to suppress fire in the fuel tank. Fire at an airplane crash may be suppressed by releasing the reactive agent from the container at the crash site to produce an active species to catalytically interfere with a fire at the crash site.
