A ceiling ventilation hood and fire protection system includes a ceiling ventilation hood, the ceiling ventilation hood defining an upper plane and a lower plane with a filter disposed between the upper and lower planes, and at least two nozzles each having an outlet defining a discharge axis with the outlet disposed in the ceiling ventilation hood between the upper and lower planes to provide overlapping protection of a hazard zone. Each of the nozzles define a spray pattern to effectively address a fire within the hazard zone independent of airflow through the filter. The outlets of the at least two nozzles are positioned at least 54 inches above the hazard zone.

Fire protection systems and methods for ventilation hoods

Preferred systems and methods for ceiling ventilation hood fire protection are provided in which fire protection nozzles are installed within a ventilation hood () to address a fire in a hazard zone (HAZ) below the ventilation hood. The fire protection nozzles () are disposed proximate the ventilation filters () or ports within the ceiling ventilation hood to provide overlapping protection of the hazard zone independent of airflow through the hood.

A release device for a tandem axle of a semi-truck is a compressible piston and cylinder, with the piston rod extending out of one end of the cylinder and biased into an extended position by a biasing mechanism such as compressed gas in the cylinder. A latch on the cylinder is releasably engageable with an indent on the piston rod to hold it in a retracted position. A hook on the cylinder engages over the handle of a manual release rod for a truck tandem axle, with an enlarged head on the end of the piston rod bearing against part of the frame adjacent the release rod with the piston rod in the latched, retracted position. Release of the latch puts biasing force on the piston rod, urging the cylinder outwardly away from the frame to pull out the release rod.
