  • Patent number: 5611882
    Abstract: A cellulose mixture including a protein based adhesive binder and colorant. The mixture can be compression molded or extruded and upon curing in the presence of microwave or radio frequency energy or in thermally controlled appliance, produces board or shape formed stock. The produced stock exhibits colorations and a grain pattern comparable to natural stone. Unlike stone, the material exhibits a light weight, low density, structural rigidity and ready machinability. A preferred method includes admixing separate, colorized batches of feedstock, each feedstock includes shredded waste newsprint, soybean flour, water and a colorant; reducing the moisture content of each feedstock or a proportioned admixture of several feedstocks, such as by air drying or compressing or performing the admixture in the presence of heat; compacting the admixture to final shape; and curing the shaped material. Final forming and finishing apparatus complete the process.

  • Patent number: 5593625
    Abstract: Fiber-reinforced protein-based biocomposite particulate material containing a legume-based thermosetting resin and cellulosic material, and rigid biocomposite pressure-formed materials produced therefrom, are provided. The particulate material and resultant pressure-formed materials contain the legume-based resin and fibrous cellulosic material in amounts such that the ratio of cellulose solids to resin solids is about 0.8:1.0 to about 1.5:1.0. Particularly preferred pressure-formed materials also include a secondary thermosetting binder, such as an isocyanate.

  • Patent number: 5587300
    Abstract: The present invention provides a method to increase the production of a regulatory molecule, i.e., a molecule that regulates cell behavior, such as a cytokine or a protooncogene, in a population of transfected cells, whether normal (resting or activated) or tumor cells. The method involves mutating a native or "wild type" cDNA sequence that encodes an mRNA sequence for a regulatory molecule to form a mutant cDNA sequence capable of producing a more stable mRNA sequence.

  • Patent number: 5582705
    Abstract: The invention provides a side-entry optical excitation geometry for use in a multiplexed capillary electrophoresis system. A charge-injection device is optically coupled to capillaries in the array such that the interior of a capillary is imaged onto only one pixel. In Sanger-type 4-label DNA sequencing reactions, nucleotide identification ("base calling") is improved by using two long-pass filters to split fluorescence emission into two emission channels. A binary poly(ethyleneoxide) matrix is used in the electrophoretic separations.

  • Patent number: 5570781
    Abstract: A disc support structure formed from a sheet material having at least one pair of opposing side walls separated a fixed distance by a back wall. At least one pair of laterally aligned, opposing slots are located on the opposing side walls for receiving and retaining edges of a media disc. The pair of opposing slots may be angled relative to the back wall so that a surface of the media disc is visible through a display plane. The disc support structure may be inserted into an outer housing for packaging purposes.

  • Patent number: 5571864
    Abstract: The invention relates to melt-miscible polyolefin blends, and a process for preparing the melt-miscible blends, of two or more polyolefins. Matching, within defined limits, the segment length of a modifying polyolefin with the segment length of a primary polyolefin, such as polypropylene or an ethylene/alpha-olefin copolymer, provides blends of the "matched" components which blends were heretofore unknown to be melt-miscible. A broad range of polyolefin blend compositions, and of polyolefin blends containing other polymers made compatible or dispersible with the polyolefin blend compositions, are defined, all of the blend compositions having at least one melt-miscible polyolefin phase.
