Robert D. Waldron 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: 5016980
    Abstract: Systems for deviating and (optionally) converging radiation include two optical devices preferably in parallel planes with one device producing convergence, and the other divergence. Alternatively, the deviating effect can be produced by an array of pairs of dove prisms with the tips of the prisms in each pair either joined to one another or separated by dielectric of lower refractive index, and with the adjacent contiguous pairs joined periodically at the base of each prism along the contiguous surfaces or separated from one another by dielectric.
    Type: Grant

    Date of Patent: May 21, 1991
    Inventor: Robert D. Waldron
  • Patent number: 4867514
    Abstract: Such system can include, in the first plane, a first optical device for producing converging radiation from incident, substantially parallel radiation passing through the first optical device and, in a second plane, substantially parallel to the first plane, a second optical device for receiving, as incident radiation, converging radiation from the first optical device and for recollimating or reducing the degree of convergence of this incident, converging radiation as it passes through the second optical device.

    Inventor: Robert D. Waldron
  • Patent number: 4310334
    Abstract: The present invention relates to a method for producing gaseous or liquid fuels or hydrocarbons from solid mineral sources and, more particularly, to a process for producing solid compounds, hereinafter designated fuel precursors, capable of releasing or generating flammable gases or liquids by chemical and/or physical conversion phenomena and to the process and methods to accomplish said fuel generation. The fuel precursors consist primarily of carbides formed from two or more metallic elements combined with carbon. The precursors additionally may contain minor amounts of free metal, unreacted carbon or other impurities.

    Inventor: Robert D. Waldron
  • Patent number: 4014706
    Abstract: New compositions of matter each consisting essentially of a solid solution of compounds and a halide binder aid. The novel compositions have melting points above 1800.degree. C, high mechanical integrity, low thermal conductivity, and are essentially non-reactive with molten reactive and refractory metals. The novel compositions sinter at 1000.degree. to 1300.degree. C.
