A dryer appliance that includes a fire extinguishing system is provided. In one aspect, the dryer appliance includes a drum rotatably mounted within a cabinet. The drum defines a chamber for receipt of articles for drying. The dryer appliance includes a water inlet valve in fluid communication with a steam nozzle operable to deliver water into the chamber to form mist or steam. The dryer appliance also includes an extinguisher nozzle in fluid communication with the chamber of the drum and with the water inlet valve. Upon detection of a fire, water is provided to the extinguisher nozzle and the extinguisher nozzle directs a stream of water into the chamber to extinguish the detected fire.

Methods, systems, and devices for disrupting phenomena are disclosed. An example device can comprise a transducer configured to receive a signal and output a longitudinal wave based on the signal. The example device can comprise a wave enhancer coupled to the transducer and configured to direct the longitudinal wave into a form having lower attenuation in a medium than the longitudinal wave as output from the transducer.

A fire suppression system in which the water supply line is fitted with repeating arrays or groups of sprinkler heads. Each array is composed of at least two side-discharge sprinklers. The side-discharge sprinklers in each array are aimed so that their coverage areas point in opposite directions. Each side-discharge sprinkler includes a lateral heat shield. The lateral heat shield has a concave heat-concentering side that focuses radiant heat toward the sprinkler's trigger, and a convex heat-scattering side that disperses radiant heat away from the trigger. In some embodiments, the array can include one or more vertical-discharge sprinklers. The vertical-discharge sprinkler may include a heat collector to facilitate early activation of its trigger.

An example apparatus includes a cabinet body and a first storage receptacle at the cabinet body. The first storage receptacle is to temporarily store an electronic device. The apparatus further includes a second storage receptacle at the cabinet body. The second storage receptacle is to temporarily store another electronic device. The second storage receptacle is separate from the first storage receptacle to prevent physical access to the first storage receptacle through the second storage receptacle. The apparatus further includes a fire suppression mechanism to independently suppress a fire in the first storage receptacle or a fire in the second storage receptacle.

An explosion control system of a comminuting installation for materials is provided for controlling unintended releases of energy by the materials. Additionally, a comminuting installation and a method for operating an explosion control system are provided. The explosion control system has at least one pressure control device. The at least one pressure control device allows for control of the propagation of pressure increases as a result of releases of energy by materials in the comminuting installation.

Apparatus and method for disposing of hot coals, e.g. charcoal briquettes after barbecuing or coals from a campfire. Sand and rain water are provided in a double-chamber device to cool it below ignition temperature. By strategically deploying the apparatus in campgrounds and forest preserves, park rangers may provide campers and hikers with a more effective tool for ensuring the fire is fully extinguished. Sand and rain water are provided in a double-chamber device to cool it below ignition temperature.

Water mist fire protection systems and methods for the protection of data centers having a raised floor defining an interstitial space beneath the floor. The systems and methods include the location of a plurality of automatic water mist nozzles above and/or beneath the floor to generate a water mist for effectively addressing a fire in the presence of a flow of forced air ventilation through the interstitial space. The systems and methods of water mist fire protection include the interconnection of the automatic water mist nozzles to a water supply to provide for dry pipe or preaction systems and methods. Water mist fire protection of data centers using fire propagating cable is also provided.
