  • Publication number: 20110021664
    Abstract: A method of producing an elastomer composite. The method includes A) combining a first fluid comprising elastomer latex with a second fluid comprising particulate filler; B) causing the elastomer latex to coagulate, thereby forming masterbatch crumb; C) bringing the masterbatch crumb to a water content of about 1 weight percent to about 20 weight percent, thereby forming a dewatered coagulum; D) removing water from the dewatered coagulum by subjecting the dewatered coagulum to mechanical energy, thereby causing the dewatered coagulum to heat as a result of friction, while allowing the dewatered coagulum to achieve a temperature of about 130° C. to about 190° C., wherein water content is reduced to about 0.5% to about 3% and wherein substantially all of the decrease in water content is accomplished by evaporation, thereby producing a masticated masterbatch; and E) subjecting the masticated masterbatch to at least an additional 0.3 MJ/kg of mechanical energy while further reducing the water content.

  • Patent number: 7825199
    Abstract: Further improvements have been made in processes for controlled polymerization of free radically (co)polymerizable monomers mediated by a transition metal complex participating in a redox reaction which involves transfer of a radically transferable atom or group to and from an initiator or dormant polymer and the growing active polymer chain ends. Two improvements involve the choice of counterion in the transition metal complex. In one improvement the transition metal is held in close conjunction with a solid support through interaction with a counterion directly attached to the support. This cognition also allows for improvements in catalyst utilization including catalyst recovery and recycle. In another improvement, particularly suitable for controlled polymerization of certain monomers with an expanded range of transition metals, the function of counterion and ligand in the development of the transition metal based catalyst is superseded by use of salt containing a soluble organic counterion.

  • Publication number: 20100235859
    Abstract: Improved channel mapping is provided wherein both virtual channel information associated with the currently-tuned channel, as well as physical channel information associated with this same channel is added to a television system's channel map. User inconvenience associated with errors in the virtual channel information may be mitigated since the television system's channel map will contain, not only the standard virtual channel information provided by broadcast stations in their broadcast signals, but also the corresponding physical channel information for the broadcast station in question. In other embodiments, multiple channel maps may be maintained and be user-selectable.

  • Publication number: 20100229193
    Abstract: Alternative-channel user selectivity is provided when a user tunes to a broadcast channel for which the desired broadcast station corresponding to such broadcast channel has been reassigned. In one embodiment, after tuning to broadcast channel in response to a user input, it may first be determined if in fact the desired broadcast station corresponding to the tuned broadcast channel has been reassigned. If so, one or more alternative broadcast channels corresponding to the desired broadcast station may be identified, and an alternative channel availability indicator may then be displayed to the user to provide alternative-channel user selectivity.
