Abstract: An oil atomizer apparatus for essential and fragrant oils includes at least one atomizer that engages with a container of essential and fragrant oils, and a body with a generally hollow interior and having a mixer housing associated with one surface of the body. An oil feeder tube extends from the mixer housing and through a surface of the body to the container of essential and fragrant oils. The mixer housing includes a compressed air inlet of a first diameter which is larger than a second diameter of the inlet, which passes to a diffusion chamber in the mixer housing having a passage to the body of the container. The application of compressed air to the inlet of the mixer housing causes the essential and fragrant oils to be dispersed to air in a fine droplet form through at least one aperture in the body.

Abstract: An improved atomization jet assembly for aromatherapy essential oil diffuser wells. It does not loose the cap during handling. It uses the capillary of liquids principal to draw essential oils between the exterior of the jet FIG. 12 and the inner cap profile FIG. 7. The flow of liquid is stopped by a capillary break 40. The Ventura principal is then used to create a low pressure area between the top of the jet ball 44 and the inside radius of the cap 65. An air/oil mixture blows out of the cap orifice 66 with the aid of an air pump. The net result is increased availability of air molecules attaching to oil molecules and making them airborne and breathable.

Abstract: A nozzle spray assembly for insecticide that can be readily connected to an outlet pipe of an air blower to conveniently spray an area free of insects. The assembly is fully portable and made of two halves that define nozzle openings that may or may not be adjustable. The high pressure air flowing past the nozzle openings draws insecticide from a container through the spray assembly and nozzle openings. The fluid sucked out of the nozzle openings is sheared across the upper surfaces of the nozzle openings and turned into micro-droplets and dispersed into the air from the blower, creating a mist flow that can be directed to the area of treatment. The assembly is provided with adjustable means for connecting it to various sizes of pipe. The assembly is portable or compact, highly effective and can be used with readily available equipment.

Receiving portion 52 includes pressure regulating valve 77 for regulating the pressure of gas from the pressurized gas source at a given gas flow rate and a pressure indicator 78 for indicating pressure of gas flowing through receiving portion 50.

Abstract: An installation for fighting fire, having a hydraulic accumulator which has at least one pressure container with a space for extinguishing liquid and a space for propellant gas, a rising tube arranged in the pressure container and provided with a side opening and, at the lower part of the pressure container, a feed opening for feeding extinguishing liquid into the rising tube and further to at least one nozzle. In order to obtain an extremely small drop size of the extinguishing liquid at the final stage of the emptying of the pressure container and in order to manage with a very small amount of extinguishing liquid, the rising tube has a throttle in an area below the uppermost side opening.

Abstract: A manually actuated liquid pump sprayer, capable of being operated in both an upright position and in an inverted position, includes an adapter attached to its pump body to effect the upright and inverted spray, the adapter having first and second fluid passages extending from an adapter chamber in opposite directions for respectively inletting liquid from the container to the chamber in one of the upright and inverted positions, and being exposed to air in the container in the other such positions, the passages terminating within the chamber in opposing upright and inverted valve seats which are valved controlled by a single gravity shifting ball check valve.

Abstract: An aerosol dispenser having a swinging downtube. Further, the aerosol dispenser is preferably provided with a concave bottom when viewing the bottom from inside the container.

Abstract: A levee gate and the process for the production thereof. The levee gate of the invention includes a rectangular sheet of thermoplastic material with a rectangular sleeve located on one edge of the thermoplastic material, the rectangular sleeve being a portion of the rectangular sheet fused to the rectangular sheet. The process for the production of the levee gate includes extruding a cylindrical tube of thermoplastic material, inflating the cylindrical tube as it is extruded to provide an inflated length of tube, flattening the inflated length of tube without fusing the opposed walls of the tube to each other, and continuously fusing a portion of the opposed walls together to form a seam.

Abstract: A device for aspirating liquids which is operable from any position or orientation includes a hollow housing which communicates with a source of carrier gas and a source of gas under pressure. A nozzle is disposed within the hollow housing through which the pressurized gas is directed to produce a high speed stream of gas. An entrainment member defining an aspiration chamber for the liquid is disposed in the housing with the aspiration chamber immediately adjacent to the nozzle outlet in the housing. A multi-directional liquid flow path communicating between the housing interior and the aspiration chamber is defined by the entrainment member and the edges thereof to provide fluid communication between the aspiration chamber and any point in the housing regardless of the orientation of the device.

Abstract: The present invention is concerned with an atomizer usable in both normal and inverted orientations, in which only the liquid to be atomized is sucked up into a pressurizing chamber 7 of a pump mechanism, while completely avoiding the flow of air into the pressurizing chamber, in both the normal and inverted orientations. The sucking of only the liquid is achieved by use of a suction passage 15 for operation in the inverted orientation provided in an ordinary pump mechanism 2, the suction passage 15 being opened at its one end to the pressurizing chamber and at its other end to a space outside and above the pump mechanism, and a stop valve 13A disposed in the suction passage 15 and adapted to open when the vacuum in the pressurizing chamber has been increased beyond a predetermined level, in the operation in inverted orientation.

Abstract: A miniature type, invertible atomizing spray mechanism includes a receptacle for liquid to be atomized, and further includes at least one pressure chamber, which depends within the receptacle and is arranged to have received therein a piston with which a reciprocable spray head is arranged to cooperate. Beneath the pressure chamber is disposed a valve member which is adapted to control the suction of the liquid into the pressure chamber. The valve member opens an inlet of the pressure chamber by the reciprocal movement of the spray head. The inlet of the pressure chamber is in fluid communication with a passage leading to a three-way valve. The three-way valve includes upper and lower valving assembly which communicate with a passage extending to the cylinder of the atomizer, each of the valving assembly being in communication with the bottom of the receptacle as well as an area adjacent to the neck portion of the atomizer through elongated tubular elements.
