  • Patent number: 10588369
    Abstract: This disclosure addresses a problem in relation to the environmental destruction that excessive apparel production can produce. In various embodiments, existing textile products are deconstructed into pieces of fabric and then reassembled into apparel in a manner that creates minimal or zero waste. In some embodiments, the fabric pieces will be positioned inside of one or more pattern pieces so as to completely cover each one without overlapping its border. The positioned pieces will be treated with an adhesive and then have a paper layer adhered to it to hold the positioned fabric pieces in place while they are stitched together. Then, the resulting sandwich will be soaked to remove the paper and dissolve the adhesive. The resulting unified fabric component will then be available to be stitched together with other similarly formed fabric components to form a garment.

  • Patent number: 10494491
    Abstract: The present invention includes the efficient dispersion and high loading of fillers in a thermoplastic polymer matrix. In a first general embodiment, the present invention includes a method wherein fillers are first synthesized and dispersed in a liquid monomer. The liquid monomer is then polymerized to a solid. The nanofillers may be silver nanoparticle/nanowire fillers. Ethylene glycol may serve as a solvent, reducing agent as well as precursor monomer for polymerization. In a second general embodiment, the present invention includes a method wherein fillers may be separately synthesized (or obtained commercially) and then added and dispersed in a liquid monomer. The liquid monomer is then polymerized to a solid. In a third general embodiment, a composite is synthesized using interfacial polycondensation. This is accomplished by aggressive mixing of two solvents during the reaction. The aggressive mixing forms microdroplets (i.e.

  • Patent number: 10472008
    Abstract: An embodiment is developed for a cylindrically shaped, elliptical rolling robot that has the ability to morph its outer surface as it rolls. The morphing actuation alters lengths of the major and minor axes, resulting in a torque imbalance that rolls the robot along faster or brakes its motion. A control scheme is implemented, whereby angular position and horizontal velocity are used as feedback to trigger and define morphing actuation. A goal of the control scheme is to cause the robot to follow a given velocity profile comprised of steps and ramps. Equations of motion for the rolling robot are formulated, which include rolling resistance torque caused by deformation of the outer surface tread. A computer program solves the equations of motion, and resulting plots show that by automatically morphing its shape in a periodic fashion, the rolling robot is able to commence from an initial position, achieve constant average velocity and slow itself.

  • Publication number: 20190337829
    Abstract: There is provided herein a roof for a reactor vessel that utilizes a weighted floating cover. The cover is free to move up and down within the vessel as the fluid level changes during the operational cycle. In some embodiment, the cover itself is not directly connected to the reactor vessel or its sidewall, but instead is held in place and supported from above by truss-like support members that permit movement of the cover in concert with the changing fluid level in the vessel. In an embodiment, the support members are anchored proximate to the top of the reactor vessel.

  • Publication number: 20190316999
    Abstract: This disclosure relates generally to enabling a user to (1) determine the radial stiffness of the outer surface of a winding or wound roll, and (2) when coupled with a winding/contact model results in a virtual instrument allowing the user to explore the residual stresses due to winding in roll-to-roll manufacturing process machines, and (3) allows the user to predict winding defects and hence roll quality based upon the known residual stresses. Wound roll models require the input of a radial modulus of elasticity which is state dependent on interlayer pressure. The hardware of the disclosure can be used to determine this radial modulus and serves to enable the user to (1) use winding/contact models and (2) with measurements made during or after winding enable the user to estimate the winding residual stresses.

  • Patent number: 10422902
    Abstract: A method is herein presented to statistically combine multiple seismic attributes for generating a map of the spatial density of fractures. According to an embodiment a first step involves interpreting the formation of interest in 3D seismic volume first to create its time structure map. The second step is creating depth structure of the formation of interest from its time structure map. In this application geostatistical methods have been used for depth conversional, although other methods could be used instead. The third step is extraction of a number of attributes, such as phase, frequency and amplitudes, from the time structure map. The next step is to project the fracture density onto the top of the target formation. The final step is to combine these attributes using a statistical method known as Multi-variant non-linear regression to predict fracture density.

  • Publication number: 20190262488
    Abstract: According to an embodiment, there is provided herein a method of using electrolyzed oxidizing water ice (EO ice) as a Cleaning-In-Place (CIP) method that reduces antimicrobial contamination. One embodiment is utilized in connection with beef grinders. In one embodiment, EO ice was prepared by freezing 200 mg/L free chlorine-containing EO water at 20° C. overnight. The EO ice and, optionally, EO ice/water mixture was then ground within an operating meat grinder. The EO ice treatment in combination with EO water has the potential to reduce cross-contamination and could serve as an easy to apply antimicrobial intervention to improve overall safety of ground beef.

  • Publication number: 20190184601
    Abstract: This system includes a concrete identification technology that is used in taking, testing, monitoring, and labeling concrete samples or members using custom labels called a tag. This tag comprises a series of corresponding labels, one for the outside of the form, and on for the inside of the form that becomes part of the concrete sample. These tags are physically bonded to the concrete specimen with only minimal impact on its shape and properties. In some embodiments the tags will contain a hook-and-loop or fiber type surface texture (protrusions) which is placed in the form with the protrusions facing the fresh concrete. The tag can also contain electronic circuitry to gather and track information about the concrete and the surrounding environment. This will eliminate the need to relabel the samples after demolding while also measuring a number of other parameters about the concrete and its performance.

  • Patent number: 10316014
    Abstract: This disclosure relates generally to the facile and selective mono-perfluoro and -polyfluoroarylation of Meldrum's acid to generate a versatile synthon for highly fluorinated alpha-phenyl acetic acid derivatives which provide straightforward access to fluorinated building blocks. The reaction takes place quickly and all products were isolated without the need for chromatography. An embodiment provides an alternative strategy to access alpha-arylated Meldrum's acids which avoids the need for aryl-Pb(IV) salts or diaryliodonium salts and provides access to the tertiary product which was not previously synthetically accessible. The synthetic versatility and utility of the Meldrum's acid products is demonstrated by subjecting the products to several derivatizations of the Meldrum's acid products as well as photocatalytic hydrodefluorination which provide access to difficult but valuable synthetic targets such as multifluorinated aromatics.

  • Patent number: 10155851
    Abstract: According to an embodiment, natural polymers will be used to enhance the biodegradability of nanocomposites, increase potential use of sustainable polymer matrices, improve the interlaminar fracture toughness of graphite/epoxy composites and attain complete nanoparticle dispersion through covalent bonding of nanoparticles and natural polymers. The starch derivatives containing POSS (polyhedral silsesquioxane) were synthesized by reacting natural polymer with different POSS molecules in a solvent in presence of a catalyst. Interlaminar fracture toughness testing results from the epoxy based nanocomposites containing 3, 5, 7, and 10 wt % POSS modified natural polymer in the interlaminar area are presented. The biodegradability of the composites is expected to improve through the incorporation of the natural polymer derivatives.
