Abstract: A mobile firefighting system includes a water cannon enabled for spraying slush on or near a fire. The slush includes solid material (e.g., ice, solid fire retardant) that is projected farther than a liquid could be projected using high pressure. The slush has enhanced fire suppression and fire protection characteristics compared to a liquid. Multiple tanks add enhanced slush chilling capability (e.g., through sequenced chilling) and provide redundant backup systems. A mobile cannon includes multiple reducing nozzles that can be aimed by a rotating base and hydraulic cylinder (for raising and lowering). Continuous tracks and winches contribute to all-terrain capabilities.

In a subsequent embodiment of the disclosure, the automatic fire extinguisher releases both the fire retardant and water into the atmosphere. The automatic fire extinguisher is formed with one moving part and no mechanical linkages. The subsequent embodiment is formed with two moving parts and no mechanical linkages. The automatic fire extinguisher comprises a compressed retardant gas, a high-pressure gas tank, a release valve, a nozzle, a whistle and a housing. The subsequent embodiment comprises the components of the prior embodiment and further comprises a chamber, a plug, water, and a check valve.

Abstract: An unheated, essential oil diffuser relies on a pressurized air stream to educt oil from a reservoir, followed by separators including separation chambers and an annular channel. The latter is a long channel having an aspect ratio (L/d) of from about 10 to about 120, for length L and thickness d. Thickness d is effective diameter, also known as hydraulic diameter (4 times c.s. area, divided by “wetted” or exposed perimeter), and may be from about 25 to about 100 thousandths of an inch (0.6 to 2.5 mm) across the thin passage, with a target range of from about 55 to 75 mils (0.7 to 1 mm). This geometry provides laminar flow at Reynolds number values less than a few hundred for virtually its complete distance of from under one inch (25 mm) to over three inches (76 mm).
