  • Patent number: 8662192
    Abstract: A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomized mist of very small droplet size is mixed with the pressurized gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged through spreaders (26, 28). The source (5) of the water is pressurized by a feed (30) from the source of pressurized inert gas. The mass flow rate of the water will therefore reduce as the pressure of the gas decays. This tends to maintain the ratio of the mass flow rate of the water to the mass flow rate of the gas constant. This is found to produce and maintain an advantageous distribution of droplet size in the discharged unit.

  • Publication number: 20110180627
    Abstract: The invention discloses a cap of spray mineral water bottle, including cap body, spray means and water locking means. This cap of spray mineral water is used with resilient mineral water bottle body to form a multifunctional spray mineral water bottle, which can ensure normal drinking of mineral water as well as carry out spray drinking of water by means of squeezing the bottle body to transform bottle body and increase the pressure inside the bottle, thus making water to enter inlet from the outlet of water locking means on the cap, and to enter the atomizing channel through the water channel, finally to be sprayed from the spray aperture. Furthermore, in the open air or in the dusty and hot environment, you can place the mineral water bottle upside down, put the nozzle to face your body or surrounding, and squeeze the bottle body to spray, thus reducing surrounding temperature, as well as subsiding dust by combining dust and spray to make you feel cool, fresh and comfortable.

  • Publication number: 20110079656
    Abstract: Systems and methods for energy-saving and water-saving devices are disclosed. In some embodiments, a head assembly is coupled to receive a liquid flow from a liquid supply and a gas flow from a gas supply, wherein the head assembly defines a mixing region configured to receive the liquid flow and the gas flow, and a dispensing portion configured to receive a combined flow from the mixing region. In some implementations, a spray nozzle may sprayably introduce the liquid flow into the mixing region. In other implementations, a plurality of curtain flows may be drawn through apertures into the dispensing portion by the combined flow. In still other implementations, a portion of the combined flow dispensed by the head assembly may be recaptured into the gas flow.

  • Publication number: 20100294857
    Abstract: In order to ventilate shower streams exiting from a hand-held shower, the invention proposes disposing a ventilation device not in the hand-held shower itself, but in the shower hose (1) through which the hand-held shower is supplied with water. The invention particularly proposes disposing the ventilation device in the fitting (1, 20, 30) for connecting the shower hose either to the water inlet side or to the hand-held shower. Furthermore, a backflow preventer (13) may be disposed in the ventilation device. The air supply to the ventilation device may be carried out by a channel (12) formed by an intermediate space between the terminal nut (3) and the hose exterior side.
