Abstract: A device for ejecting an at least diphasic mixture includes an injection inlet for a liquid and a gas, a distribution chamber for producing a first liquid-gas mixture, an ejection nozzle of the first liquid-gas mixture in a main direction defined by an axis-vector. The ejection nozzle has a geometry comprising, on its length at least, a minimal section or neck at a location of the axis-vector. Among others things, due to the nozzle geometry, the expansion obtained inside the ejection nozzle allows the first liquid-gas mixture from the distribution chamber to be converted into a second mixture, according to the flow configuration, consisting for instance of a diphasic mist jet having an ejection range and liquid particle size that can be controlled according to the liquid and gas mass flow and to the absolute pressure at the injection inlet.

Abstract: A propulsion device for an agent, such as an extinguishing or cooling agent, contained in a cavity has at least a cap and a port configured to open above a calibrated pressure inside the cavity. A pressure generator is fastened to the cap and triggers the propulsion of the agent. The pressure generator has at least two containers, each having an exit ending inside the cavity and releasing a propulsion gas. At least one container is pressurized with an inert-type gas, such as helium, suited for minimal temperature fluctuations induced inside the cavity during a relief of pressure of the gas from at least one of the containers. When the gas expands it is the direct mechanical propellant of the agent.

Abstract: A method of up-scaling a first structure of samples representing a first property, the first structure having a source resolution, into a second structure of samples representing the first property, the second structure having a target resolution, on basis of a third structure of samples representing a second property, the third structure having the source resolution and on basis of a fourth structure of samples representing the second property, the fourth structure of samples having the target resolution, the method comprising: assigning weight factors to respective first samples of the first structure of samples on basis of differences between respective third samples of the third structure of samples and fourth samples of the fourth structure of samples; and computing the second samples of the second structure of samples on basis of the first samples of the first structure of samples and the respective weight factors.

Abstract: A multi-functional carpentry tool includes a base member having a longitudinal T-shaped groove formed therewithin and a rule member. A T-shaped slide member is positioned within the groove and has a threaded aperture formed therewithin. A knob has a threaded stem operatively received within the threaded aperture for selectively securing the base member and the rule member together in frictional engagement maintaining the base member and the rule member in selected positions relative to one another and permitting each of a sliding and pivoting movement of the rule member relative to the base member. Linear measuring scale indicia is provided in each of the base and rule members. Angular measuring scale indicia and a squaring groove is also provided within the base member. A spring biased pin is movably mounted within the knob for defining pivot axis and facilitating arc scribing effort.
