Abstract: This self-pressurizing seal invention embodies resilient, non-corrosive and fire resistant construction with an internal pressure responsive chamber whereby fluids entering such chamber through a unidirectional fluid orifice are trapped in the internal chamber and whereby the resulting pressure differential causes outward expansion from the internal chamber to external sealing surface of multiple, pliable and conjoined ridges to form a series of redundant circumferential seals against the axial pipe surface with corresponding force to prevent the outward flow of fluids from the pipe juncture in a pipe coupling or valve.

Abstract: A projectile is provided which may evenly disperse an inhibiting substance upon impacting a target. The projectile may comprise a shell having a plurality of grooves formed on the shell's exterior surface about an axis of symmetry. The grooves may be equidistantly spaced apart from adjacent grooves. The shell defines an interior cavity that may be filled with a mixture comprising an inhibiting substance and filler with the inhibiting substance being operative to inhibit the motor function of a person and the filler being an inert material which does not react with the inhibiting substance. Preferably, the inhibiting substance will comprise substantially less than 50% of the shell's interior cavity, and preferably about 2% to 1% of the shell's interior cavity. The projectile may be shot at the target such that the projectile breaks open at the grooves to form a cloud of the inhibiting substance such that the target inhales the inhibiting substance and is passivated.

Abstract: A flashlight for dispensing a substance from an aerosol canister, the flashlight including an elongated housing having a front end, a rear end, and a central longitudinal axis, the aerosol canister being slidably received within the housing. At least one light emitting diode disposed approximate the front end of the housing and an elongated spray tube having a proximal end and a distal end, the proximal end being connected to the aerosol canister and the spray tube extending parallel to the central longitudinal axis such that the distal end extends beyond the front end of the housing.
