Patents by Inventor Charles Schenck Wiley

Charles Schenck Wiley 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).

  • Publication number: 20180170814
    Abstract: Disclosed is a method for fabricating a solid article from a boron carbide powder comprising boron carbide particles that are coated with a titanium compound. Further disclosed herein are the unique advantages of the combined use of titanium and graphite additives in the form of water soluble species to improve intimacy of mixing in the green state. The carbon facilitates sintering, whose concentration is then attenuated in the process of forming very hard, finely dispersed TiB2 phases. The further recognition of the merits of a narrow particle size distribution B4C powder and the use of sintering soak temperatures at the threshold of close porosity which achieve post-HIPed microstructures with average grain sizes approaching the original median particle size. The combination of interdependent factors has led to B4C-based articles of higher hardness than previously reported.

  • Patent number: 9321187
    Abstract: A process for the fabrication of a SiC-based article that includes preparing an aqueous suspension with SiC powder, a titanium source, a carbon source and boron carbide powder, spray drying the mixture to obtain a powder, preparing a green body from the powder, applying heat treatment to the green body in a pyrolysis/thermolysis step, pressureless sintering the green body, optimally followed by HIPing for further densification.

  • Patent number: 8434396
    Abstract: A ballistic tile for use in an imbricated pattern of like ballistic tiles to achieve coverage of a protected area by the imbricated pattern, while having rounded corners to limit the potential for spalling on ballistic impact. The ballistic tile may include a strike face that is generally undulating to laterally deflect at least a portion of the impact force, and to induce turning of the ballistic projectile on impact to further distribute the impact force. The ballistic tile may also include one or more features on an obverse and reverse side thereof that, when arranged in an imbricated pattern, limit lateral motion of the tiles on ballistic impact, and/or laterally transmit the energy of the projectile for deflection and absorption thereof.
