  • Patent number: 10767018
    Abstract: This invention relates to a process for producing an isotactic polypropylene based composite, comprising: reactive blending of isotactic polypropylene homo-polymer; polypropylene grafted with a carboxylic anhydride or a furan type moiety such as maleic anhydride grafted polypropylene; and an amino silane such as (3-aminopropyl)triethoxysilane to produce an isotactic polypropylene based composite such that the crystallization temperature of the isotactic polypropylene based composite is in a range of about 120° C. to about 126° C. The reactive blending can further take place in the presence of an organically modified nanoclay.

  • Publication number: 20140216920
    Abstract: A method is provided of producing nanoparticles in the size range 1 nm to 1000 nm through the synthesis of one or more precursor fluids. The method includes providing a fluid medium comprising at least one precursor fluid and generating an electrical spark within said fluid medium to cause pyrolysis of said at least one precursor fluid in a relatively hot plasma zone to produce at least one radical species. Nanoparticles are formed by nucleation in the fluid medium in a cooler reaction zone about the plasma zone, where the radical species acts as a reactant or catalytic agent in the synthesis of material composing the nanoparticles. The spark is created by an electrical discharge having a frequency between 0.01 Hz and 1 kHz, and a total energy between 0.01 J and 10 J. The nanoparticles may comprise silicon, or compounds or alloys of silicon, and are typically useful in electronic and electrical applications.

  • Patent number: 7159675
    Abstract: A method of drilling a borehole in an earth formation wherein a plurality of selected solid magnetisable particles is inserted into the borehole, the particles being susceptible of forming a filter cake layer at the borehole wall and being made of a material susceptible of being exposed to magnetic forces when subjected to a magnetic field. A section of the borehole is drilled, and at least part of the filter-cake layer is removed from the wall of the drilled borehole section by inducing a selected magnetic field in the borehole. The magnetic field exerts magnetic forces to the particles, thereby withdrawing the particles from the wall.

  • Patent number: 4285744
    Abstract: The invention concerns a process for the reproduction of oil paintings or similarly surface-textured images by use of a relief form transferred from an original and a smooth thermoplastic color photo film that is imprinted corresponding to the original, with the film, together with a reenforcing back ply, being laid onto the relief form in fitting alignment and with the film and reenforcing ply being deformed by heating to correspond to the surface texture of the original.

  • Patent number: 4076406
    Abstract: A method of and apparatus for toning an exposed electrophotographic member in a camera or other electrostatic imaging device which uses liquid toner comprising toner particles suspended in a dispersant.The method contemplates running the liquid toner into a chamber containing the photoconductive surface of the electrophotographic member and a metal plate parallel with one another and spaced apart as two boundaries of the chamber. During the toning operation, a low d.c. bias is applied across the chamber between the photoconductive surface and the plate of a polarity opposite to that characterizing the latent image such as to repel toner particles from the photoconductive surface, but the voltage of the bias is low enough not to affect increments of the surface which have substantial charge on them. The result is that said increments with very little charge are left with practically no adhering particles.
