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.

A device for retaining a snowboard boot includes a base on which the sole of the boot is adapted to rest, a turned-up heel support portion extending upwardly from the base at the rear of the device, and a dorsal support element. The dorsal support element extends upwardly from the heel support portion and is journalled on the heel support portion along an axis substantially contained in the median vertical longitudinal plane of the base. The device includes an elastic return device that elastically opposes inclination of the dorsal support element on at least one of the lateral sides of the device by rotating about the axis during rocking of the boot. The device provides binding support during lateral bending while preserving freedom of movement.

A skate having a skate boot with a non-lasted boot shell, the shell having a first non-lasted three-dimensional sub-shell and a second non-lasted three-dimensional sub-shell, the second sub-shell being interior to and adjoining the first sub-shell, the first sub-shell comprising a first material having a first density and the second sub-shell comprising a second material having a second density, the second density being less than the first density, the shell being shaped so as to have a heel portion, an ankle portion, a lateral portion, a medial portion, and a sole portion; and a ground-engaging assembly disposed on an underside of the skate. Additional sub-shells are possible. Methods of manufacturing the skate boot shell, including molding and build-up, are also disclosed.

A ski boot (1) includes an inner boot (1.1) that is designed to accommodate the skier's foot and a leading shell (1.2) that surrounds the inner boot (1.1), making it possible to hold the skier's ankle in place. This boot (1) also includes a calf support (3) attached to the shell (1.2) that is designed to accommodate the skier's calf, and a thigh support (5) that forms an angle (α) with the calf support (3) that is designed to accommodate the skier's thigh when the latter is in the bent position. Preferably, the boot includes a damping element (8, 23, 27) that is installed between the calf support (3) and the thigh support (5), as well as elements (25, 26) for adjusting the angle (α) between the calf support (3) and the thigh support (5).

The skate boot construction includes a unitary plastic heel/ankle counter insert which may be secured externally or internally to a soft boot mounted on a skate truck. The insert includes two spaced side portions joined by a U-shaped heel section which extend along the sides of a skater's foot. Above the side portions and the heel section are two forwardly projecting side flaps joined by an arcuate back section which are connected to the spaced side portions by two outwardly bowed hinge sections positioned over a skater's ankle bones. An arcuate slit extends through the heel/ankle counter between the heel section and arcuate back section and runs for a distance along either side of the heel/ankle counter. End slits extend transversely above and below each end of the arcuate slit. Cutaway portions below the side flaps extend inwardly toward the end slits and with the end slits define the edges of the bowed hinge sections.
