  • Publication number: 20090239436
    Abstract: Spray-formed, anti-burst, leak-self-sealing coating structure applicable to the outside surface of a fuel container, and an associated application methodology. In an operative condition relative to such a surface, the coating structure includes (a) a solid, continuous-phase body of fuel-reactive, high-elastomeric material in the form of an expanse having an inner side applied to such a surface, and a spaced, outer side, (b) a field of distributed, fuel-reactive, fuel-imbiber beads embedded in and throughout the expanse of said body, generally spaced from, and centrally between, the body's inner and outer sides, but exposed to neither such side, and (c) an anti-burst fabric web having meshes formed by elongate, stretch-resistant fibers extending generally centrally within and throughout bead field. Meshes in the fabric web, and beads in the bead field, are relatively sized appropriately to permit the ready mesh-through-passage of beads during spray-formation of the coating structure.

  • Publication number: 20090208724
    Abstract: An embedded-object composite product including a solid-state mass of PET, an object embedded in the PET material mass, and a zone possessing a continuous material-density gradient in the PET material mass, with more-dense PET material residing closely adjacent the embedded object, and less-dense PET material residing more distant from that object. This product is produced effectively by non-destructively heating the PET mass from its solid state to allow it to flow as a liquid, by then pressing the object into the heated PET mass to perform object embedment and to create a declining PET-material density in the region adjacent, and progressing from adjacent, the embedded object, and by thereafter cooling the mass to re-solidify it.

  • Publication number: 20090169757
    Abstract: A method for spray-creating a composite-material layer on the outside surface of a liquid container to defeat liquid leakage following a projectile penetration of the container. The method includes (a) defining a by-weight percentage blend of two penetration-reaction materials, where the contribution of one such material, an initially liquid and wet-sprayable, but subsequently curable-to-dry, high-elastomeric body-forming material, is larger than that of the other material, which takes the form of a population of dry, liquid-imbibing bead elements, (b) creating weight-percentage-differentiated, simultaneous sprays of these two materials for contact-blending, during spraying, into a composite spray en route in the air toward the region of a target liquid container, and (c) as a part of such creating, controlling the amount of en route, inter-material, contact blend time between the two materials.

  • Publication number: 20090169733
    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.

  • Publication number: 20090050629
    Abstract: A method, and a self-sealing, layer-effect, stealth-reaction liner, for sealing against fuel leakage from the wound-punctured wall of an FT synthetic liquid fuel container. The liner includes (a) an elastomeric body defined by spaced, opposite faces, formed of a material which is non-reactive to FT fuel, and (b) nominally shrouded in a region within the liner body, inwardly of the faces, a distribution of liquid-imbiber beads which react to contact with FT fuel to initiate liquid-imbibing and material-swelling actions. The method includes (a) preparing, for installation in such a container, a liner with a non-fuel-reactive, substantially continuous-material elastomeric body having opposite faces, and (b) within that body, a non-facially exposed, normally body-shrouded, central distribution of fuel-reactive liquid-imbiber beads.

  • Patent number: 7437987
    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.

  • Publication number: 20080220259
    Abstract: A bulk, generally elastomeric and pliable, layered mat formed to permit selective trimming into size-chosen mat trims/tiles, each of which is structured to perform as a self-puncture(wound)-sealing, defined-liquid-reactive, anti-puncture-leakage coating element applicable bondedly to the outside surface of a selected wall in a container holding the defined-liquid. The mat is made by preparing it as a generally elastomeric, pliable, layered arrangement of coatings formed of self-puncture-healing, defined-liquid-reactive, anti-puncture-leakage material, or materials; and is applied for use in relation to a selected container wall by (1) trimming, from the prepared mat, one or more trims/tiles shaped for specific use on the outside surface of that wall; and (2) applying and surface-bonding the one or more trims/tiles to the outside surface of the selected wall.
