Patents by Inventor Lori J. Groven

Lori J. Groven 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: 11125545
    Abstract: The present invention is a pyrotechnic time delay system that is improved over prior-art designs. Specifically, the system described herein comprises at least one delay element. The delay element or delay dements each have an input charge, a delay composition, and an output charge. Both the input charge and the output charge are igniter compositions and are comprised of the same components despite having different functional goals. The input charge and output charge compositions preferably contain titanium, manganese dioxide, and polytetrafluoroethylene. The delay composition may be modified from current formulations to include manganese and manganese dioxide, or tungsten and manganese dioxide. The system disclosed herein may be comprised of one delay element, or it may be modular wherein multiple delay elements are connected in series.
    Type: Grant

  • Patent number: 9193638
    Abstract: An environmentally safe, nontoxic energetic time delay composition useful in small diameter aluminum tubes (i.e., typical military delay housings), which provides desired delay propagation rates of from less than about 2 to about 38 mm/s through such delay housings—the compositions being compressed stoichiometric mixes of Ti and C powders; Ni and Al powders; a combination of Ti/C and 3Ni/Al powders; and a combination of Ti/C and Ni/Al powders, diluted with inert alumina.
