  • Method and apparatus for circular knitting with elastomeric yarn that compensate for yarn package relaxation
    Patent number: 7540174
    Abstract: When elastomeric yarns are unwound and fed to the needles of a circular knitting apparatus, a yarn package relaxation profile is set, or determined, with corresponding adjustments made to the unwinding speed based on such package relaxation profile. Variably compensating for a varying package relaxation while knitting results in more uniform properties in a circular knit fabric and improved elastomeric yarn yield.
    Type: Grant
    Filed: April 19, 2005
    Date of Patent: June 2, 2009
    Assignee: INVISTA North America S.ar.l.

  • Synthesis of metal phthalocyanines
    Patent number: 4077973
    Abstract: Metal phthalocyanines having a narrow particle size distribution are synthesized via the phthalodinitrile or phthalic anhydride-urea route using hexachlorobutadiene as the diluent. Higher yields and shorter reaction times are also realized by carrying out the syntheses in this manner.
