Patent number: 8389063Abstract: 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.Type: GrantFiled: February 25, 2009Date of Patent: March 5, 2013Assignee: High Impact Technology, Inc.Inventors: Thomas S.

Patent number: 8236220Abstract: 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.Type: GrantFiled: August 15, 2007Date of Patent: August 7, 2012Assignee: High Impact Technology, LLCInventors: Russell A. Monk, Thomas S. Ohnstad, Lance A. Hicks

Associated methodology involves applying directly onto such a surface, by one only of the processes including casting and spraying, an inner layer formed of the mentioned high-elastomeric material, and thereafter forming, outwardly of the applied inner layer, and also of the same high-elastomeric material, another layer by the other one only of the two, mentioned processes.Type: ApplicationFiled: August 25, 2011Publication date: March 8, 2012Applicant: High Impact Technology, L.L.C.Inventors: Russell A.
