Patent number: 10093036Abstract: A process for separating a mixture of materials using a segregation media within a vessel having a central baffle structure which shuggles the mixture by oscillating the baffle structure at a frequency and amplitude. The mixture of materials may have overlapping densities with the segregation media having a density within the overlapping region. Polymers PE and PP may be separated in flake form. For a mixture of materials of differing densities, water may be the segregation media. Shuggling is combined with controlling the flow of water through the vessel at a set velocity. Embodiments are described for separating plastics and mineral ore.Type: GrantFiled: July 27, 2015Date of Patent: October 9, 2018Assignee: IMPACT LABORATORIES LTD.Inventors: Surya Vesavkar, Steven Andrew Burns, Ian Vallance

Patent number: 10039847Abstract: The present invention provides a fluorescent silica-based nanoparticle that allows for precise detection, characterization, monitoring and treatment of a disease such as cancer. The nanoparticle has a range of diameters including between about 0.1 nm and about 100 nm, between about 0.5 nm and about 50 nm, between about 1 nm and about 25 nm, between about 1 nm and about 15 nm, or between about 1 nm and about 8 nm. The nanoparticle has a fluorescent compound positioned within the nanoparticle, and has greater brightness and fluorescent quantum yield than the free fluorescent compound. The nanoparticle also exhibits high biostability and biocompatibility. To facilitate efficient urinary excretion of the nanoparticle, it may be coated with an organic polymer, such as poly(ethylene glycol) (PEG). The small size of the nanoparticle, the silica base and the organic polymer coating minimizes the toxicity of the nanoparticle when administered in vivo.Type: GrantFiled: September 25, 2017Date of Patent: August 7, 2018Inventors: Michelle S. Bradbury, Ulrich Wiesner, Oula Penate Medina, Andrew Burns, Jason S. Lewis, Steven M. Larson, Thomas P. Quinn

Patent number: 8450028Abstract: A method of recording a volume holographic image is described in which a holographic recording medium containing a photoreactive dye is exposed to a plurality of coherent light sources emitting at a wavelength to which the dye is sensitive, thereby forming an interference fringe pattern therein. The photoreaction occurring in the areas of constructive interference generates a periodic array of photoreacted areas of the dye and unreacted areas of the dye. This generated interference fringe pattern may contain, but does not have to contain any image or other encoded information. Selected areas of the interference fringe pattern are then exposed to actinic radiation in such a manner to partially or fully bleach, remove, or deactivate the photoreactive dye fringe pattern, thereby producing a holographic pattern, shape, or image formed by areas of the interference fringe pattern that were not bleached, removed, or deactivated.Type: GrantFiled: March 29, 2011Date of Patent: May 28, 2013Assignee: Sabic Innovative Plastics IP B.V.Inventors: Michael T.
