Abstract: A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided on the aircraft, but is not activated and mixed with tank water until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and doses it with gel emulsion. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including mixing paddles or sparging with gas. In one embodiment, a hollow tower of telescoping form has a float to keep an upper end near a surface in the tank and a sparging gas entry is a controlled distance below the surface, such that gas of limited pressure, such as from a ram air inlet can sparge and mix the water and activated polymer gel emulsion effectively.

Abstract: An aromatherapy device may define a plurality of wells arranged in an array to be filled with fluid as scented pairs such that two adjacent wells may be positioned beneath nostrils of a user while resting a portion of the device against the upper lip. The wells may be formed in respective cylinders positioned between the portion of the device that is designed to rest against the lip. There may be a plurality of wells that face a first direction and that face an opposite second direction. The wells may be similar shaped and sized so as to receive similarly viscous fluids therein having different scents associate therewith. The viscosity of the fluids should be high enough to resist the pull of gravity and preclude the fluid from flowing out of the well when the device is positioned upside down and some of the wells are, at least temporarily, downwardly facing.
