Abstract: Differential-type dry pipe valves for fire protection systems are provided. The valve includes a body with a clapper assembly disposed in an internal passage of the valve body between an inlet and an outlet. The clapper assembly is movable between a closed position and an open position to respectively prevent and permit fluid flow through the passage from the inlet to the outlet. With the clapper assembly in the open position, an internal mechanism is positioned to stop the clapper moving to the closed position. The valve includes a resetting assembly having a knob exterior to the body. Translation of the knob toward the outlet moves the internal mechanism which permits the clapper assembly to move to the closed position.

Abstract: Группа изобретений относится к технике ликвидации аварий для предотвращения возгораний, взрывов, далее купирования, при ликвидации последствий аварийных и технологических разливов сжиженного природного газа или сжиженного углеводородного газа и может быть использовано в энергетике, транспорте, газодобывающей, газоперерабатывающей и химической промышленности. Способ купирования разливов сжиженного природного газа или сжиженного углеводородного газа включает нанесение на поверхность разлива сжиженного газа слоя водо-воздушной пены. На поверхность разлива сжиженного газа наносят гибридную водо- воздушную пену, получаемую в результате турбулентного перемешивания в процессе спутного движения струй воздушно-механической пены низкой кратности и воздушно-механической пены средней кратности посредством системы содержащей средства генерации воздушно-механической пены низкой и средней кратности, изготовленные с возможностью получения и нанесения на поверхность разлива сжиженного газа по крайней мере одной струи гибридной водо-воздушной пены, получаемой в результате турбулентного перемешивания в процессе спутного движения струй воздушно-механической пены низкой кратности и воздушно-механической пены средней кратности.

Abstract: An automatic dry horizontal sidewall fire protection sprinkler assembly for residential fire protection. The sprinkler assembly includes an elongate tubular outer housing having a first end and a second end. The second end of the housing defines an outlet opening and an internal channel and contact surface proximate the outlet opening. A fluid deflection member is coupled to the housing at a fixed distance from the outlet opening. An internal fluid control assembly includes an ejectable member that is ejected out the outlet opening and displaced out of the fluid flow path between the housing and the fluid deflection member. The sprinkler assembly provides a plurality of coverage areas suitable for residential fire protection over a plurality of nominal operating temperatures up to 200 °F.

Abstract: 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.
