A fire sprinkler valve trigger has a body or tube segmented into opposite segments joined together at a joint by a fusible material with a predetermined and selected melting temperature less than a melting temperature of the opposite segments. An exterior of the body or tube comprises a layer added to the exterior, and comprising a preselected color corresponding to and designating the melting temperature of the fusible material. The body or tube, including the joint and the fusible material, being exposed and visible so that the layer on the exterior of the body or capsule is exposed and visible.

A nozzle is provided having a low precipitation rate and uniform fluid distribution to a desired arcuate span of coverage. The nozzle has an inflow port having a shape corresponding to the desired arc of coverage and a size for effecting a low precipitation rate. The nozzle also has a deflector surface with a water distribution profile including ribs for subdividing the fluid into multiple sets of fluid streams. There are at least two fluid streams for distant and close-in irrigation to provide relatively uniform distribution and coverage. The nozzle may be a unitary, one-piece, molded nozzle body including a mounting portion, an inflow port, and a deflector portion.

The invention relates to a device (1) for releasing an aerosol, comprising a cylindrical upper housing (3) with a cylindrical top protrusion (30) extends downwards from the top wall (32) so that a predetermined space (34) is formed between the circumferential inner side of the upper housing and the outer side of the cylindrical top protrusion (30), wherein the top protrusion (30) comprises a bolt (18) protruding downwards from the bottom end (36) of the top protrusion, and wherein the upper housing (3) comprises at least one opening (7) for releasing the dispersed aerosol, a cylindrical lower housing (2) with a bottom floor (9), further including an bottom opening (5) in the bottom floor (9) of the lower housing (2), a cylindrical bottom protrusion (13) enclosing the bottom opening (5) and protruding upwards so that a predetermined space (11) is provided between the inner side of the lower housing (2) and the outer side of the cylindrical bottom protrusion (13) forming a reservoir for the aerosol, a support frame (15) fixedly connected to the inner side of the bottom and/or the side of the lower housing (2); and a float (12) that covers the cylindrical bottom protrusion (13), wherein the inner circumferential shape of the float (12) matches the outer shape of the cylindrical bottom protrusion (13) and wherein the float (12) is supported by the support frame (15) so that the distance C between the bottom protrusion (13) and the float (12) is essentially the same over the whole circumference, wherein the distance T of the top end of the float (12) to the inner side of the top end of the cylindrical bottom protrusion (13) is greater than the respective circumferential distance C.

A water mist nozzle (2) for a fire suppression system comprises a nozzle head (4) including a discharge nozzle (6) for supplying a fluid jet (12); a support structure (8); and a stationary deflector element (10). The stationary deflector element (10) is fastened to the support structure (8) and comprises a body with a substantially round outer periphery having a base portion (28) and a substantially conical upper portion (22) with a central peak (24). The substantially conical upper portion (22) provides a plurality of flowpaths (26), the flowpaths (26) extending substantially radially from a radial position close to the central peak (24) in a direction towards the outer periphery, the flowpaths (26) having at least one portion (26a, 26b, 26c) of decreasing slope, in which the slope of the bottom of the flowpaths (26) decreases along the flow direction towards the outer periphery. The stationary deflector element (10) is fastened to the support structure (8) such that the central peak (24) of the substantially conical upper portion (22) of the stationary deflector element (10) faces the discharge nozzle (6) and that the fluid jet (12) exiting the discharge nozzle (6) impinges onto the central peak (24) and is distributed to the environment, substantially in a lateral direction, through the plurality of flowpaths (26).

Sprinkler guards to protect fire protection sprinklers in their installed and operative positions. A fire protection sprinkler guard includes a structure with a hinged arrangement to flexibly receive a fire protection sprinkler. A latch connection operates in combination with the hinge of the guard to form a rigid cage structure to shield and protect the sprinkler.

An injection head for liquid fire extinguishing agent that has an injection head including an injection head body connecting with a pipe providing the liquid fire extinguishing agent, an orifice plate arranged in the injection head body and formed with an orifice through which flowing the liquid fire extinguishing agent and, a porous member having a block shape arranged in an exiting part of the orifice and, a baffle plate arranged contacting with an end surface of the porous member opposite side of the exiting part of the orifice; and the baffle plate covers at least a projected area of a circumscribed circle of the orifice of the end surface of the porous member and, the liquid fire extinguishing agent is released via a gap formed between the injection head body and the baffle plate.

A fire suppression nozzle assembly includes a spray-type nozzle for spraying a fire suppression fluid. The spray-type nozzle includes a body portion defining a passage extending longitudinally through the body portion for conveying the fire suppression fluid. The spray-type nozzle also includes a deflector portion coupled to the body portion and configured to spray the fire suppression fluid onto a fire suppression target area using a radial spray pattern.

A portable water spreader has a water tank with a coupler to couple to and be elevated and tilted by a front-end loader. Discharge pipes are coupled to the tank with spray heads. Vent pipes are coupled to the tank.

The invention includes components and methodology for fixed and semi-fixed systems for extinguishing fire in large industrial flammable liquid storage tanks, including aerated foam projecting nozzles discharging substantially focused streams together with aeration chambers and risers.

The invention relates to an automatic dispenser (100) of fluid products contained in cartridges, these being able to accommodate a large number of large-capacity cartridges while having reduced over-inking. The dispenser comprises: a frame provided with N slots (E) for cartridges (200A, 200B, 200C) of products, these cartridges being each provided with a reservoir and with a metering pump; an actuation system (30) for the cartridges, comprising: a motor (31) that is able to generate a force for actuating the metering pump of the cartridges; a selective transmission mechanism (32) that is able to selectively transmit the force generated by the motor to at least one of the metering pumps; a recess for a removable container; the N slots (E) being arranged substantially horizontally and in a stepped manner.
