Abstract: Spray nozzle device for spraying a cast strand or similar metallurgical products with a misty air/water mixture for uniformly cooling the cast strand. The air/water mixture is produced in a mixing chamber which acts as a diffusor and includes an air inlet, a water inlet, and a nozzle outlet approximately in alignment with the air inlet. The air inlet is arranged in an air inlet nozzle, the tip of which protrudes into an upper region of the mixing chamber and preferably has air outlet holes oriented perpendicular to a longitudinal axis of the mixing chamber. Water enters near the tip through at least one water outlet hole oriented perpendicular to the longitudinal axis and placed such that the water jet exiting the water outlet hole flows past the air outlet holes. The air flow or air pressure and the water flow or water pressure do not influence each other.

Abstract: A system for fragrancing air includes an adjustable fan that is used to generate an air flow to push atomized fragrance oil from an output orifice of the system. The fragrance in the air is generated from atomized fragrance oil, where liquid fragrance oil can be stored in a cartridge bottle assembly and then atomized with compressed air in a collector assembly in the system. When the system is mounted on a wall or ceiling, the adjustable fan can be used to direct the fragrance downward at any number of angles from the system. The system can be programmed to adjust a fan speed and various settings of the fragrance delivery.

Abstract: The invention relates to an apparatus and process for solid-state deposition and consolidation of powder particles entrained in a subsonic or sonic gas jet onto the surface of an object. Under high velocity impact and thermal plastic deformation, the powder particles adhesively bond to the substrate and cohesively bond together to form consolidated materials with metallurgical bonds. The powder particles and optionally the surface of the object are heated to a temperature that reduces yield strength and permits plastic deformation at low flow stress levels during high velocity impact, but which is not so high as to melt the powder particles.

The device comprises a tank containing the single dose having an inlet orifice for compressed gas, and an outlet orifice. The device further comprises a manually actuated gas pump having a gas supply communicating with the inlet orifice of the tank via an intermediate channel. The intermediate channel has a length of narrowed section that is closed in a sealed manner by a plug which is held in the narrowed section so that when the pressure of the gas supplied by the pump reaches a predetermined threshold, the plug is expelled towards the tank to open the intermediate channel. The device includes an abutment element to limit the displacement of the plug towards the outlet orifice of the tank of substance. The abutment element is constructed to guarantee that the compressed air can continue to floe through the outlet orifice when the plug is in its abutment position.

Abstract: A device is used for spraying and atomizing a liquid which is held in a container which can be emptied by air pressure. If in a device of this kind a liquid nozzle projects into a mixture nozzle disposed coaxially in front of it, so that an annular space provided for air around the liquid nozzle is open at the front towards the mixture nozzle, the feed paths for liquid and for air must not be transposed. Such transposition occurs if the container is held upside-down during spraying. In order to avoid this disadvantage two annular spaces are provided, from which passages lead to a mixture nozzle. The two annular spaces communicate with one another via throttle slots. Because of the two annular spaces the liquid can also be sprayed when the container is upsidedown.

A vapor tap hole 26 is provided in the dip tube 18 above the liquid entrance hole 24 and below the initial liquid level 14. The vapor tap hole 26 allows compressed gas 16 to enter the tube 18 and mix with the liquid 20 therein when the liquid level 28 has fallen below the vapor tap hole.

Abstract: The present valve for a spray container has a mixing chamber for mixing a gas propellant with the active ingredient for producing a finely atomized spray. The gas propellant enters into the valve housing by means of sufficient clearance between the walls of the valve body and the valve housing. The active ingredient and the gas propellant both enter into a mixing chamber through simultaneously openable and closable passage openings. The valve stem of the present valve has two channels. One channel in the valve stem provides a flow path for the gas propellant and for the active ingredient mixture, the other channel in the stem providing a flow path substantially for the gas propellant alone. These channels combine in a second mixing chamber resulting in still further atomization of the spray and a more efficient utilization of substantially the entire container content.

Abstract: Foam is produced when a reservoir is deformed by squeezing. When pressure is applied to the reservoir, a vent passage is sealed by a flexible washer, while liquid is forced up a tube and through a passage in a cylindrical member to a region at the top of that member. Air is forced through another passage and swirls into the same region to mix with the liquid. As the pressure of the mixture increases, a ball valve located above the region, is caused to open which allows discharge of the mixture. When the pressure is released, the valve is sealed and suction pulls the washer away from the vent to allow air back into the reservoir.

Abstract: Foam is produced when a reservoir is deformed by squeezing. When pressure is applied to the reservoir, a flexible washer seals a vent passage while liquid is forced up through a tube, a ball valve and outwardly through a radially slotted member, while air passes through orifices in the washer and along the outside of the slotted member to mix with the liquid. The mixture is then discharged when pressure is released, the valve is sealed and suction pulls the washer away from the vent to allow air back into the reservoir.
