Abstract: A humidifier bottle assembly and a method for operating a humidifier are presented. The humidifier bottle assembly includes a humidifier bottle adapted to hold water and a humidifier bottle receptacle adapted to receive the humidifier bottle. The receptacle includes a pivot point about which the bottle pivots and a biasing member adapted to situate the bottle in a given angular position in response to the amount of water contained in the bottle.

The arrangement is such that the sprinkler is devoid of any dynamic seals.

Abstract: A two-fluid atomizing nozzle incorporating a novel nozzle cap is described. The nozzle cap comprises support spokes which couple a pintle to the outer frame of the nozzle cap for holding the pintle in position. The support spokes comprise dams which prevent liquid from flowing along the length of the support spokes to the outer frame of the nozzle cap. This improves atomization by causing any liquid which flows along the spokes to reenter the high disturbance region of the nozzle. Additionally, it reduces erosion of the support spokes, particularly near the end of the spokes adjacent to the outer frame of the nozzle cap. Moreover, it reduces erosion of the interior wall of the outer frame of the nozzle cap. In another embodiment the support spokes have a non-planar inlet surface to improve atomization and to reduce erosion of the support spokes and the interior wall of the outer frame.
