Abstract: A method utilizing a spray instrumentality for spray-applying to a target surface in a target zone a defined, composite-material layer which is to play a role in defeating a liquid leak from a puncture wound created in the wall of a container holding liquid of a particular character. The method includes the steps of (a) initiating a flow toward the spray instrumentality of liquid elastomeric body-forming material, (b) at a selectable point downstream from where such initiating takes place, introducing a flow of plural, liquid-imbiber bead elements which are relevant to the mentioned particular-character liquid, (c) in a user-chooseable manner in relation to the introducing step, merging the two flows, and (d) following such merging, applying the merged flows to a target surface, thus to create the desired, defined composite-material layer which takes the form of a body of elastomeric material containing a distribution of liquid-imbiber elements.

Abstract: A deployable marker banner structure and system including (a) an elongate, rollable/unrollable fabric body having opposite ends, a long axis, and opposite faces, (b) shape-forming biasing structure operatively connected to the body, applying shape-forming biasing forces thereto at plural, spaced locations distributed along the body's long axis in a manner whereby, with the body unrolled, the biasing structure produces complex, alternating, longitudinally distributed convex and concave topography portions in the body's faces, with at least one each of such convex and concave topography portions disposed in each face of the body, and with each convex topography portion in one face of the body corresponding, and being complementary, to a companion concave topography portion located directly in the opposite face of the body, and (c) facial visibility-enhancing structure operatively present at least on the convex topography portions in the body's faces, urged by the mentioned topography portions into complex conve

Abstract: A blast shockwave shield including an upright, monolithic body having a lateral center, and front and back sides, and a blast-facing, curved strike face formed on the upright, front side of the body, including a pair of companion, laterally spaced, laterally symmetric, non-coextensive, curved, strike-face portions, each of which defines a blast shockwave-deflection vector that is aimed upwardly, and laterally outwardly away from the shield's lateral center. This structure implements a method for blast shockwave deflection which includes the steps of engaging and intercepting such a shockwave with an upright, monolithic, solid-resistance instrumentality having a pair of laterally spaced, curved, non-coextensive strike-face portions, and, by those acts of engaging and intercepting, reversely deflecting an impinging shockwave.

Abstract: Structure, and a related method, for sealing, from the outside, a leaking puncture wound in the wall of a liquid container. This structure includes a patch body having a perimetered cavity selectively securable via a self-torque-limiting bolt to the outside of such a container in a manner whereby the cavity overlies and faces the wound, with the cavity's perimeter surrounding the wound, and a patch pellet contained and confined in the cavity and formed, at least in part, of a reaction substance which, with the patch body secured to the container, reacts to contact with liquid leaking from the container at least by imbibing such liquid and swelling to apply wound-sealing pressure, and more preferably by additionally reacting with leakage liquid to form a sticky coagulant mass for aiding in applying sealing pressure to the wound.
