Patents by Inventor David Charles Nemir

David Charles Nemir 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: 9573324
    Abstract: Systems and methods for producing a dense, well bonded solid material from a powder may include consolidating the powder utilizing any suitable consolidation method, such as explosive shockwave consolidation. The systems and methods may also include a post-processing thermal treatment that exploits a mismatch between the coefficients of thermal expansion between the consolidated material and the container. Due to the mismatch in the coefficients, internal pressure on the consolidated material during the heat treatment may be increased.
    Type: Grant
    Filed: June 3, 2015
    Date of Patent: February 21, 2017
    Assignee: TXL GROUP, INC.

  • Publication number: 20140305479
    Abstract: A tubular thermoelectric device wherein conductive substrates and completion elements serve a multiple role of structural support, thermal conductance and electrical conductance. Improved system thermoelectric performance accrues from the minimization of the number of interfaces between dissimilar materials, leading to a reduction in system thermal parasitics and system electrical parasitics. By engineering the shape and orientation of substrates and completion elements, improvements in heat transfer to heat reservoirs is accomplished and improved electrical conductivity is accomplished.
