Stabilized ammunition container

Ammunition boxes may be equipped with a cohesive and adhesive shell restraining overlay adapted to restrain ammunition shells in a stabilized position. The shell restraining overlay provides sufficient adhesiveness to restrain a housed ammunition shell at a desired shell position, but allows for relatively effortless shell release without creating excessive movement or noise. The stabilizing overlay also stabilizes the shells from inadvertent spillage from the ammunition box.

Immobilizing Flexible Stowage Containers

A unique flexible container combination comprises a viscoelastomeric thermoset overlay disposed upon a flexible supportive base. Desirably, the viscoelastomeric thermoset overlay possesses exceptional adhesive, cohesive and releasability properties. In some embodiments, the flexible container combination can also exhibit antipathogenic, cleansability and/or reusability properties. The flexible container combination can maintain an adhered stowable item in an immobilized position until intentionally removed therefrom by a user. In some embodiments, the flexible container combination can be folded or rolled into a rolled-up configuration.

MODIFIED RESINS AND USES THEREOF

Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.
