Patents by Inventor Joan V. Burlew

Joan V. Burlew 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: 6635099
    Abstract: This invention provides a process for forming sintered, molded articles having improved dimensional stability. More particularly, this invention pertains to process for forming heat sinks. This process includes forming a substantially uniform copper composition comprising a polysaccharide binder, water, and copper particles; molding the copper composition under conditions sufficient to form a solid molded intermediate; and sintering the solid molded intermediate at a sufficient temperature and for a sufficient time to form a heat sink.
    Type: Grant
    Filed: January 24, 2001
    Date of Patent: October 21, 2003
    Assignee: Rutgers, The State University of New Jersey
    Inventors: Jerry C. LaSalle, Mohammad Behi, George A. Glandz, Joan V. Burlew

  • Patent number: 5746957
    Abstract: Parts from ceramic and/or metal powder(s) are shaped by a process that comprises the steps of (1) forming a mixture comprising ceramic and/or metal powder(s), a gel-forming material chosen from the class of polysaccharides known as "agaroids", a gel-forming solvent, and a gel strength enhancing agent, and said mixture being formed in a blender that provides a shearing action and being heated to raise the temperature of the mixture to about 70.degree. C. to 100.degree. C.; and (2) molding the mixture at a temperature sufficient to produce a self-supporting structure comprising the powder and gel. The parts exhibit excellent green strength and are rapidly fired without cracking, distortion or shrinkage problems.

  • Patent number: 5250251
    Abstract: A process for shaping parts from ceramic powder that comprises the steps of (1) forming a concentrated mixture in excess of 40% ceramic solids by volume, the mixture comprising ceramic powder, a gel forming material chosen from the class of polysaccharides known as "agaroids", and a gel forming material solvent and being formed in a blender that provides a shearing action and is heated to raise the temperature of the mixture to about 70.degree. C. to 100.degree. C.; and (2) molding the mixture at a temperature sufficient to produce a self-supporting structure comprising the powder and gel. The parts exhibit excellent green strength and are rapidly fired without cracking, distortion or shrinkage problems.

  • Patent number: 5087595
    Abstract: A ceramic element of a zirconia oxygen sensor is shaped from a powder mixture. The mixture, comprising a ceramic powder having an average particle size less than or equal to 1 micrometer, a gel-forming material and a gel forming material solvent, is molded at a temperature and pressure sufficient to produce the ceramic element having a density of at least 5.5 g/cm.sup.3.
