Patent number: 9821180Abstract: A fire suppressant system is a device that uses steam/super-heated water to suppress and put out fires rather than the traditional water method. The invention uses steam/super-heated water under high pressure to blow out and suppress the fire. The wet pressurized steam/super-heated water “blows out” the fire and the pressure removes (displaces) the oxygen and spark needed for the fire to continue burning. The wet steam/super-heated water works much like water to suppress and put out the fire but the additional benefits of the pressure help to reduce the fuel (air and spark) for the fire as well.Type: GrantFiled: April 8, 2016Date of Patent: November 21, 2017Inventor: Kenneth Wendlin Heck

Patent number: 9717936Abstract: A sprinkler assembly that includes a frame having a body including an inlet, an outlet and an internal passageway extending between the inlet and the outlet to define a longitudinal sprinkler axis. Two frame arms extend distally from the body, and each arm has a portion defining a cross-sectional area with a lateral surface and a medial surface spaced about a first plane bisecting the body with the sprinkler axis disposed in the first plane. An axially aligned thermally responsive glass-bulb type trigger is disposed along the sprinkler axis. The cross-sectional areas of the frame arms are asymmetrical with respect to one another about the first plane and each cross-sectional area is asymmetric about a second plane perpendicular to the first plane. The lateral surface of each arm includes an undulation to provide the sprinkler assembly with substantially consistent thermal sensitivity about the sprinkler axis.Type: GrantFiled: September 20, 2013Date of Patent: August 1, 2017Assignee: Tyco Fire Products LPInventors: Mathew R.
