Patent number: 8915307Abstract: A nozzle for a fire suppression system has a bonnet and a deflector base. An inlet port extends through the bonnet along the axis of symmetry of the bonnet. The inlet port receives an outlet end of a fire suppression delivery pipe to mount the bonnet to the pipe. The bonnet has a frustoconical surface which extends radially outward and downward from the inlet port. The deflector base is secured to and co-axially aligned with the bonnet at a predetermined distance to create a flow passageway therebetween. The flow passageway imparts a down angle to a suppressant flow discharging from the nozzle to better disperse the suppressant within the fire zone. A discharge port at the circumferential edge of the bonnet and deflector base constricts the suppressant flow to atomize the droplets of liquid suppressant discharged into the fire zone.Type: GrantFiled: December 18, 2008Date of Patent: December 23, 2014Assignee: UTC Fire & Security CorporationInventors: Muhidin Lelic, Giuliano Amantini, May L.

Patent number: 8889277Abstract: An assembly for preventing a fire resulting from the outgassing of a lithium battery in an electronic door lock includes a lithium battery, a circuit board, and a thermal insulation. The lithium battery and circuit board are housed within the electronic door lock. The thermal insulation is arranged between a door interfacing side of the electronic door lock and either or both of the circuit board and lithium battery. Another thermal management technique for preventing fire resulting from the outgassing of a lithium battery in an electronic door lock is achieved by using a battery cover that is selectively movable away from the circuit board or ignition source in response to temperature rise to ensure the lithium battery does not reach a critical temperature that may cause outgassing in close proximity to the ignition source.Type: GrantFiled: June 8, 2009Date of Patent: November 18, 2014Assignee: UTC Fire & Security CorporationInventors: Vijaya Ramaraju Lakamraju, Jean Yamanis, Ulf J.
