Abstract: An aerosol generating device generates an aerosol having a desired particle size by passing a liquid through a flow passage heated to convert the liquid into a vapor. The flow passage includes an outlet section that controls the exit velocity of the vapor and produces an aerosol with a desired particle size. The aerosol generator can be incorporated in a hand held inhaler, and the liquid can include a medicament, which is delivered to a targeted portion of the lung using the inhaler.

Abstract: There is provided a diffuser for volatile material such as a volatile aromatic or chemical agent.

A liquid-absorbent member is adapted to hold the volatile liquid.

Abstract: A nozzle for mixing and delivering two or more components and method of use thereof. One variation provides a nozzle that injects a first component, such as fuel, into a flow plume for a second component, such as nitrous oxide, for use with combustion engines. The nozzle receives two or more separate flows of components (e.g., gases and/or liquids), one of which is pressurized so as to be outputtable from the nozzle as a plume. The plume is directed so as to encompass an output extension for the other component near the plume edge, thereby enhancing mixture of the components. In addition, the plume produces a low pressure draw of the second component from the output extension, the low pressure draw varying with plume velocity, in turn varying with delivery pressure of the first component. The plume flow of the second component also atomizes the first component, further enhancing mixing.

Abstract: A suck back valve includes an ON/OFF valve mechanism which opens/closes a fluid passage by displacing a valve member together with a first piston under an action of a pressure fluid supplied into a first cylinder chamber, and a suck back mechanism which has a suction member formed deformably in a flow chamber to suck a pressure fluid contained in the fluid passage by displacing the suction member together with a second piston under an action of the pressure fluid supplied to a second cylinder chamber. The ON/OFF valve mechanism and the suck back mechanism are assembled coaxially and integrally.

Abstract: A line marker carries a spray nozzle assembly for marking or painting a line on a horizontal surface. The line marker has a hydraulic circuit which includes a reservoir for holding marking liquid therein and a tank for holding water therein. A pump can pump marking liquid through the spray nozzle during a marking mode of operation or water through the spray nozzle during a flush mode of operation. In the marking mode, at least some marking liquid is recirculated back through the reservoir to help keep the marking liquid in the reservoir agitated and mixed. In the flush mode, water is blocked from entering the reservoir and is recirculated back into the water flow from the tank. In the clean out mode, the hydraulic circuit is operated as if in the marking mode, except that the reservoir is rinsed with an external source of water with the rinse water circulating through the hydraulic circuit and back to the reservoir.

Abstract: The invention provides an emitter tube for an irrigation system, the tube being of resiliently flexible material having a base inlet end adapted to be mounted and a free outlet end adapted to be unmounted, the arrangement being such that, with liquid flowing at a sufficient rate through the emitter tube, hydraulic forces exerted by the flowing liquid on the tube cause the outlet end continuously to move about, further having a base section and an end section downstream from the base section when the end section is of greater flexibility than the base section.

Abstract: A deflector at the downstream end of a fuel tube deflects incoming fuel into an annular fuel channel in a fuel swirler of an injector. The deflector prevents direct impact of the cooler fuel on the exposed walls of the swirler body. The deflector can be formed by a tab or other integral portion of the heatshield, or as a separate piece fixed to the heatshield or swirler body. The deflector minimizes disruption of flow through any flow slots that are covered by the deflector, and may have i) a relatively small circumferential extent, such that the deflector covers only a few flow slots, ii) flow openings or slots that allow a portion of the fuel to flow inwardly of the deflector into the otherwise covered flow slot(s), or iii) a space or gap between the side(s) of the deflector and the inner walls of the annular channel.

Abstract: An assembly for distributing particulate material comprising a blower assembly preferably removably mounted on a mobile platform and structured to generate a forced flow of air along a flow path and through a manifold assembly connected to a supply of material being distributed. The manifold assembly includes a receiving segment incorporating a Venturi section facilitating the introduction of the particulate material into the forced air flow passing through a discharge conduit. The discharge conduit preferably has an extended length to facilitate distribution of the material to a plurality of locations in a variety of different environments. An applicator is selectively attached to the discharge conduit so as to facilitate distribution of the particulate material to a substantially confined space, such as a potted plant.

Abstract: A chemical injector for injecting fluid chemical into a pipeline having an axis wherein the pipeline has fluid flow moving from an upstream to a downstream direction. The chemical injector includes an injector tube having an axis substantially perpendicular to the axis of the pipeline. An injector tube tip extends from the injector tube having an angled end, wherein the angled end forms a line extending from the injector tube axis toward the downstream direction at an acute angle. A circular aperture through the tube tip angled end of the injector tube assists in dispersing the fluid chemical in the pipeline.

Abstract: An articulated fire truck (T) has an extendible and retractable boom (11) mounted on the truck and extendible to a height above the ground where a fire is burning within a building (B). A drill assembly (1) is affixed to the end of the boom for drilling through a sidewall of the building into the building's interior. The drill assembly is maneuverable to drill straight through the sidewall as well as up and down and sideways so to provide an opening into the interior of the building sufficiently large that a nozzle attached to the drill assembly can readily spray water or a fire retardant material into the interior to extinguish the fire. The drill assembly has drill bits (100) located completely about the circumference of the drill assembly to facilitate up-and-down and side-to-side cutting to more quickly penetrate into the building's interior.

Abstract: A fuel injector includes an auxiliary valve member that can assist in raising a mean injection pressure, increase a nozzle valve opening pressure, and hasten the closure rate of a nozzle valve member over an equivalent fuel injector without the auxiliary valve. The auxiliary valve member is fluidly positioned between a needle control chamber and a high pressure space, which includes a fuel pressurization chamber within the fuel injector. The auxiliary valve member includes a closing hydraulic surface exposed to fluid pressure in the high pressure space. The plumbing and the auxiliary valve member allow high pressure fuel to act upon a closing hydraulic surface of the nozzle valve member to increase valve opening pressure and mean injection pressure. The needle control chamber may be vented or may be a closed volume when the auxiliary valve member is in its closed position.

Abstract: A sprayer is disclosed that may be attached to a garden hose for cleaning exterior surfaces such as windows. By turning a flow selector in a single direction tap water from the hose first flows through the sprayer to rinse the surface to be cleaned. The flow selector can then be set to spray a mixture of cleaner (e.g., one or more surfactants) and surface modifier (e.g., one or more polymers) and water on the surface. The flow selector can then be set to an off position to allow for scrubbing of the surface with a scrubbing tool. The flow selector can then be set to rinse the surface with untreated water, and the flow selector can be turned further to rinse the surface with filtered tap water produced by a filter in the sprayer. Also disclosed are unitary cartridges providing a combined replacement of the cleaning surfactant and a filtering system for deionizing the water.
