  • Crystallization method for purification of calcipotriene
    Publication number: 20080161587
    Abstract: Provided is a crystallization method for reducing the level of impurities in calcipotriene in which a solution of a starting calcipotriene in a first process solvent, for example THF, is combined with second process solvent, for example methyl formate, and, after cooling, calcipotriene is isolated. The method can include a slurry step for reducing the level of residual first process solvent.
    Type: Application

  • Signal duration representation by conformational clock cycles in different time domains
    Patent number: 6603336
    Abstract: Circuitry and methodology for transferring a representation of a data signal between clock domains. In particular, the disclosure teaches a method for creating representations of signals input from a slow clock domain into a fast clock domain and vice versa. The methods and apparatus use a RAM-free architecture which may be easily incorporated into integrated circuits to enhance efficiency.
