20110215566 | Flexible Assembly for Sprinklers - An assembly for connecting a sprinkler to a branch line of a fire suppression system includes a flexible conduit having one end attached to the branch line. The opposite end is attached to the sprinkler. An adapter may be positioned between the conduit and the sprinkler, between the conduit and the branch line, or between the conduit and both the branch line and the sprinkler. The adapter contains a rotating joint which prevents torque from being applied to the conduit. The joint may be a ball joint, a coaxial joint or an external sleeve. The sleeve is positioned surrounding the conduit. The sleeve may have a hexagonal outer surface and rotates freely about the conduit to prevent torque from being applied to the conduit. | 09-08-2011 |
20120031632 | Dual Mode Agent Discharge System With Multiple Agent Discharge Capability - An emitter system capable of discharging an atomized liquid-gas stream or a liquid stream which atomizes into a spray has a source of pressurized gas and one or more sources of pressurized liquids. Flow of gas and liquid to an emitter is controlled by valves, and the emitter can be used to discharge either the atomized liquid-gas stream or the liquid stream. The emitter system may be used for fire suppression. | 02-09-2012 |
20130099481 | Flexible Assembly for Sprinklers - An assembly for connecting a sprinkler to a branch line of a fire suppression system includes a flexible conduit having one end attached to the branch line. The opposite end is attached to the sprinkler. An adapter may be positioned between the conduit and the sprinkler, between the conduit and the branch line, or between the conduit and both the branch line and the sprinkler. The adapter contains a rotating joint which prevents torque from being applied to the conduit. The joint may be a coaxial joint. | 04-25-2013 |
20130233430 | Flexible Assembly for Sprinklers - An assembly for connecting a sprinkler to a branch line of a fire suppression system includes a flexible conduit having one end attached to the branch line. The opposite end is attached to the sprinkler. The conduit is corrugated and has an outer surface with a plurality of crests and troughs. A sleeve co-axially surrounds a portion of the flexible conduit proximate to the sprinkler. The sleeve has a corrugated inwardly facing surface comprising a plurality of crests and troughs spaced so as to fit within the crests and troughs of the conduit and thereby prevent axial sliding motion of the sleeve relatively to the conduit. The sleeve and the flexible conduit are rotatable relatively to one another thereby preventing torque being applied to the flexible conduit through the sleeve. | 09-12-2013 |
20140174768 | DRY SPRINKLER - A dry sprinkler is provided that includes a conduit with a fluid inlet and a fluid outlet, a valve positioned near the fluid inlet and a fire sprinkler head that is positioned near the fluid outlet. The fire sprinkler head is operably connected to the valve by a tie. When the fire sprinkler head reacts to an elevated temperature condition, the tie is engaged and is operable to open the valve. In a normal state, before the fire sprinkler head reacts, the tie can be unbiased toward the fire sprinkler head. The tie can also be non-rigid and/or in a non-compressed state within the conduit. The conduit of the dry sprinkler can be flexible. | 06-26-2014 |
20140231103 | Identification Sleeve for Flexible Conduit - A sprinkler assembly has a sleeve covering at least a portion of a conduit connecting the sprinkler to a branch line of a fire suppression system. The sleeve may have a color field, contrasting color patterns, symbols, indicia, or combinations of these elements and may be used to visibly indicate characteristics of the sprinkler assembly. | 08-21-2014 |
20140332707 | Valve With Removable Seat - A valve has a housing defining an inlet and an outlet and a cavity therebetween which receives a valve seat. The valve seat defines a slot which receives a gate. The valve seat is sealingly engaged with the housing, the gate sealingly engages the valve seat and is movable within the slot between an open and a closed position using an actuator. An opening in the housing provides access to the cavity. The valve seat may be removed from the housing through the opening by attaching the valve seat to the gate, thereby attaching the valve seat to the actuator, and withdrawing the gate from the housing using the actuator. | 11-13-2014 |
20150075821 | DRY SPRINKLER - A dry sprinkler is provided that includes a conduit with a fluid inlet and a fluid outlet, a valve positioned near the fluid inlet and a fire sprinkler head that is positioned near the fluid outlet. The fire sprinkler head is operably connected to the valve by a tie. When the fire sprinkler head reacts to an elevated temperature condition, the tie is engaged and is operable to open the valve. In a normal state, before the fire sprinkler head reacts, the tie can be unbiased toward the fire sprinkler head. The tie can also be non-rigid and/or in a non-compressed state within the conduit. The conduit of the dry sprinkler can be flexible. | 03-19-2015 |
