  • Systems and methods for heterogeneous storage systems
    Patent number: 11928336
    Abstract: Systems and methods for managing a storage system are disclosed. The storage system includes a first storage device and a second storage device different from the first storage device. A first storage operation is received for a first portion of a file, and a data structure associated with the file is identified. Based on the data structure, the first storage device is identified for the first portion of the file. The first storage operation is transmitted to the first storage device. In response to the first storage operation, the first storage device updates or accesses the first portion of the file.
    Type: Grant

  • Manufacture of polycarbonates
    Patent number: 7495064
    Abstract: A method of producing a polycarbonate is provided. In an embodiment of the present invention the method includes the steps of: (i) introducing to a melt polymerization reactor system a reaction mixture having a first dihydroxy compound and an acid stabilizer, a carbonate source, and a polymerization catalyst system containing K2HPO4; and (ii) allowing the reaction mixture to polymerize thereby forming polycarbonate.

  • Method for preparing a polycarbonate oligomer mixture at low temperature for manufacturing polycarbonate
    Patent number: 7041775
    Abstract: The present invention provides a method of making polycarbonate oligomers, polycarbonate, molded articles formed from polycarbonate, and an apparatus for making polycarbonate. An oligomer mixture is first prepared by the steps of providing an equilibration system comprising a vessel, a reaction mixture contained within the vessel, and means for mixing the reaction mixture contained within the vessel wherein the reaction mixture comprises a melted activated diaryl carbonate composition, and a catalyst present in sufficient amount to initiate an oligomerization reaction between a dihydroxy composition and the activated diaryl carbonate to form polycarbonate oligomers.
