Patents by Inventor D. Erich Weerth

D. Erich Weerth has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8037803
    Abstract: This invention is a novel system for blast protection. It consists of lightweight, sectional or continuous barriers made of a novel blast resistant fiber reinforced polymer resin matrix composite, which may be fabricated on site. The barriers are lightweight and thin enough that they may be used in many spaces where barriers made from conventional construction materials are impossible, impractical, or undesirable. The novel barriers of this invention have the additional advantage of allowing for aesthetically appealing and architecturally harmonious designs. In order to minimize weight, the barriers may be designed such that the cross section varies with height, providing adequate resistance in areas of high blast loading, but allowing for thinner cross sections in regions of lowering load.
    Type: Grant

  • Publication number: 20090092443
    Abstract: This invention is a novel system for resisting barrier breach resulting from kinetic energy (i.e. ramming impacts). It consists of lightweight, sectional or continuous barriers made of a breach resistant fiber reinforced polymer resin matrix composite, which may be fabricated on site. The barriers are lightweight and thin enough that they may be used in many spaces where barriers made from conventional construction materials are impossible, impractical, or undesirable.

  • Patent number: 7461453
    Abstract: The invention is an explosive resistant liner, located inside an enclosed space, and made from a blast resistant material. The liner is preferably constructed inside the enclosed space, consisting of lay-up, curing and assembly steps utilizing a collapsible tool. The invention is particularly applicable to blast protection for aircraft cargo holds.

  • Publication number: 20060065656
    Abstract: This invention is a novel lightweight blast resistant container. It consists of containers made of a blast resistant fiber reinforced polymer resin matrix composite. The invention employs a novel construction configuration whereby the container is created by the appropriate nesting of composite parts to create a cube, box or multi-faceted geometry. As a result of the nesting, the box like geometry exhibits characteristics that cause the geometry to behave more like a sphere than a box when subjected to internal blast pressures. Such an approach provides an optimized minimum weight solution by fully utilizing the entire material volume, whereby ultimate tensile strength can be simultaneously developed everywhere in the container.
