  • Publication number: 20230115147
    Abstract: The present disclosure provides to a novel continuous processing method to prepare sheets comprising cellulose nanofibril (CNF) and carboxymethyl cellulose (CMC). Single screw extrusion was utilized to continuously process mechanically fibrillated cellulose nanofibrils (CNF) into sheets. Water-retention ability and stability of CNF suspensions containing different processing aids was assessed through centrifugation and zeta potential analysis. Subsequently, highly loaded pastes (up to ˜25 wt. % total solids content) containing the best performing processing aids (carboxymethyl cellulose (CMC), xanthan gum (XG), and anionic polyacrylamide (aPAM)) and CNF were prepared using a Brabender with Banbury mixer-head at a dry weight ratio of either 0.1 to 1 or 0.15 to 1, respectively. Validation of the mixing procedure proved that highly loaded CNF pastes can be processed in under 40 minutes, saving up to 40 days in preparation and drying time.

  • Patent number: 10898599
    Abstract: A method for treating wood packaging materials using Radio Frequency heating includes the steps of heating wood packaging materials using RF heating and applying a pressure before the heating or incrementally applying a pressure during the heating until a temperature of the wood packaging materials reaches at least 60° C. and that temperature is maintained for at least 1 minute.

  • Patent number: 9580657
    Abstract: A carbonaceous feed pyrolysis apparatus is provided including two or more hot particle fluidized beds, and one or more positive displacement apparatus for the transfer of hot particles between two or more of the beds, wherein one or more of the fluidized beds contains a combustion zone. A bio-oil production process is also provided, including pyrolysis of a carbonaceous bio-mass using two or more fluidized beds, including a first combustion zone carried out in one or more combustion fluidized beds in which a particulate material is fluidized and heated, and a second pyrolysis zone carried out in one or more pyrolysis fluidized beds in which the hot particles heated in the combustion zone are used for pyrolysis of the bio-mass.

  • Publication number: 20140150138
    Abstract: A novel Beta vulgaris serine proteinase inhibitor gene (BvSTI) and its protein are identified in response to insect feeding on B. vulgaris seedlings. BvSTI is cloned into an expression vector with constitutive promoter and transformed into Nicotiana benthamiana plants to assess BvSTI's ability to impart resistance to lepidopteran insect pests. A reporter gene GUS is also cloned into an expression vector under control of the BvSTI gene promoter and transformed into N. benthamiana plants to determine if the promoter induces expression of the gene upon wounding and insect feeding. BvSTI DNA and amino acid sequences and the promoter sequences from various strains of B. vulgaris are obtained. Transformation of BvSTI cDNA under control of constitutive promoter or an inducible promoter into economically valuable plants is useful for effective control of insect pests that feed on the economically valuable plants and utilize serine proteases for digestion.

  • Publication number: 20100159505
    Abstract: A fluorescent spectroscopic method and apparatus for real time direct detection of transmissible spongiform encephalopathies in central nervous system tissue by monitoring the fluorescence of intrinsic markers in the tissue by illuminating the tissue with UV or visible light having an appropriate wavelength, and the resulting emission spectra is detected and examined in the region from 350 to 650 nm. A higher intensity in this region is indicative of infected tissue. The apparatus and method would not interfere with existing slaughterhouse line speeds or procedures, and could be used on live animals.

  • Publication number: 20080283757
    Abstract: A system and method for determining a level of effective residual ink concentration (ERIC) in a piece of recycled paper. The piece of paper is illuminated with a beam of radiation and an amount of the beam of radiation reflected and transmitted by the piece of paper is measured. The level of ERIC is determined as a function of the reflected and transmitted radiation.

  • Publication number: 20080126008
    Abstract: A method and apparatus are provided for the determination of a surface area of a fastener, such as a threaded fastener. Specifically, an image of the fastener is acquired, and the image is separated into at least two regions, for instance three regions, and the surface area of each region is determined. The surface areas determined for each region are summed to determine the surface area of the fastener.

  • Patent number: 5228621
    Abstract: The present invention is drawn to an apparatus and process for applying material, such that it is dispersed in a pulsed manner, in micronized form, to agricultural commodities, while preventing drift of the micronized material to nontargeted areas. The instant invention employs a canopy which is passed over the agricultural commodity wherein a micronizing means is used to apply material, such as a pesticide, to an agricultural commodity within the canopy. The micronized material is preferably electrostatically charged when applied to the commodity.
