  • Patent number: 5028362
    Abstract: A method for molding ceramic powders comprises forming a slurry mixture including ceramic powder, a dispersant, and a monomer solution. The monomer solution includes at least one monofunctional monomer and at least one difunctional monomer, a free-radical initiator, and a aqueous solvent. The slurry mixture is transferred to a mold, and the mold containing the slurry mixture is heated to polymerize and crosslink the monomer and form a firm polymer-solvent gel matrix. The solid product any be removed from the mold and heated to first remove the solvent and subsequently remove the polymer, whereafter the product may be sintered.
    Type: Grant
    Filed: November 13, 1989
    Date of Patent: July 2, 1991

  • Patent number: 5010560
    Abstract: In data logging applications an apparatus for real-time stamping data includes a reference time base, a short stopwatch circuit operative for generating a short-time stamp, and a long stopwatch circuit operative for generating at intervals a long-time stamp. Data to be logged with the short-time stamp is combined therewith and stored. A controller circuit controls the storage of the data and of the long-time and the short-time stamps. The controller circuit stores the long-time stamp at predetermined intervals.

  • Patent number: 4894194
    Abstract: A method for molding ceramic powders comprises forming a slurry mixture including ceramic powder, a dispersant for the metal-containing powder, and a monomer solution. The monomer solution includes at least one multifunctional monomer, a free-radical initiator, and an organic solvent. The slurry mixture is transferred to a mold, and the mold containing the slurry mixture is heated to polymerize and crosslink the monomer and form a firm polymer-solvent gel matrix. The solid product may be removed from the mold and heated to first remove the solvent and subsequently remove the polymer, whereafter the product may be sintered.
