Described is signalling device for extinguishers or hydrants, comprising a first valve body connected to a tank of liquid and/or powder product to be dispensed, a second valve body connected to a hose equipped with a nozzle for dispensing product and a handle for activating the dispensing of the product equipped with a control lever; inside the handle is housed a safety plug shaped in such a way as to keep the control lever in an inactive position. The plug has, at a relative end portion, a magnet, which activates a sensor present on an electronic card located inside the control lever, designed to detect the presence of the plug. Moreover, the plug is made of transparent plastic material and at least one LED is positioned on a base facing a lower portion of the plug, in such a way that the LED produces a luminous emission which spreads for the entire plug, thereby operating as a luminous wave guide.

The manometer of the invention is an evolution of the EP 2687269 invention patent, of the applicant itself, in which by including a NB IoT communications module (Narrow Band, Internet of things) (10), the need to have a communications switchboard as a bridge between the manometer and the server or control center is avoided. Additionally, the manometer includes a presence and distance sensor (15) that allows to remotely monitor that the installation associated to the manometer complies with the safety regulations related to the accessibility that such installation must have, generating an alarm signal when the same may be blocked by any element.

The present invention relates to a cap assembly for converting a container of a carbonated drink into a fire extinguishing device. The present invention also relates to a method for extinguishing a fire using a container of water or carbonated drink producing environmentally friendly and human safe stream.

A fire extinguisher includes a liquid fire extinguishing media, and first and second gases inside of a storage vessel at an operating pressure, and a discharge tube extending between a control valve and the fire extinguishing media. At least a portion of the first gas is dissolved in the fire extinguishing media. The control valve can be operated to control discharge of the fire extinguishing media via the discharge tube whereupon at least a portion of the second gas enters a flow of the fire extinguishing media via one or more holes in the discharge tube forming bubbles of the second gas in the flow of the fire extinguishing media. The fire extinguishing media exiting the control valve can pass through a nozzle which can causing first and second portions of the fire extinguishing media to collide forming a plume mist of the fire extinguishing media.

An agitator for disposition within a cavity of a vessel body containing a particulate includes a weighted portion and a stirring portion. The agitator is positioned and disposed relative to the vessel body to move the stirring portion through the particulate in response to movement of the weighted portion in response to gravitational and/or inertial forces acting on the weighted portion due to movement of the vessel body. Particulate storage vessel arrangements and methods of particulate mixing are also described.
