Abstract: The disclosure provides a method for the bonding of polytetrafluoroethylene sheets of various thicknesses to various surfaces. A method may include removing contaminants from a substrate for the application of the polytetrafluoroethylene sheet; applying adhesive to an etched side of the polytetrafluoroethylene sheet; and installing the polytetrafluoroethylene sheet to the substrate.

Abstract: Barrier structure placeable as an anti-fuel-leak coating on the outside surface of a liquid container. This coating includes a first-type layer structure formed of a high-elongation-capable elastomer which also is capable of imbibing container leakage liquid, and of swelling in the process, and a second-type layer structure disposed adjacent one side of the first-type layer structure, composite in nature, and possessing bead-like components entrained in the same elastomer employed in first-type layer structure, with these entrained components structured also to be imbibers of leakage container liquid, and to expand on imbibing such liquid. Also disclosed is methodology which involves applying to the outside surface of such a container a coating possessing cooperative, penetration-sealing characteristics including (a) elastic elongatability before breakage within a range of about 300-400%, and (b) leakage-liquid-contact swelling, accompanied by leakage-liquid/coating contact-triggered coagulation.

Abstract: Structure, and a related method, for sealing, from the outside, a liquid-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 liquid-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.

Abstract: An armor panel for defeating a projectile strike including (a) a substantially planar core structure having spaced, generally parallel-planar strike and opposite faces, and elongate, circumsurrounding edge structure extending generally normally between these faces to define a perimeter for the core structure, (b) stranded core-wrap structure substantially fully enveloping the core structure, and possessing elongate, tension-load-bearing (TLB) strands which extend at angles relative to one another across the mentioned faces, and substantially parallel to one another in a distribution along the perimeter defined by the edge structure, and (c) a high-elastomeric coating which is distributed over at least those portions of the core-wrap structure which are disposed adjacent the strike face and the edge structure.
