Abstract: A fire-suppression system includes an aviation vehicle and a fluid transport and delivery system. The fluid transport and delivery system is coupled to a vehicle frame of the aviation vehicle and is located within a cabin of the vehicle frame. The fluid transport and delivery system includes a tank having an exit aperture formed in a bottom wall of the tank, a plug aligned with the exit aperture of the tank, and a plug actuator configured to move the plug along an axis from an open position, in which the fluid stored in the tank passes around the plug and through the exit aperture, to a closed position, in which fluid is blocked from exiting through the exit aperture.

Abstract: A component spatula tool system including an elongate grip handle structure, and a generally planar blade which is releasably grippable by the handle structure. The handle structure has a pair of opposed, selectively openable and closeable, matchingly grip-patterned clamping pads that define a nip region, the blade has opposite sides possessing matchingly grip-patterned clamping sites whose grip patterns are complementary to those of the clamping pads, and the clamping pads and clamping sites accommodate, via operative interengagements of their respective grip-patterned characteristics, positive-lock, universally invertible, plural-position clamp locking of the blade within the nip region.
