A system for minimizing the effect of null zones in an interrogation zone of a marker detection system. The system includes a reference antenna system configured to produce a first reference electromagnetic field during a first time period. The antenna system also includes a phase canceling antenna system configured to produce a second electromagnetic field substantially in phase with the reference electromagnetic field during the first time period and a third electromagnetic field substantially out of phase with the reference electromagnetic field during the first time period. The phasing of the first field or the second and third fields may be continuously switched while the phase of the other is held constant. A method of spatially shifting null zones in an interrogation zone of a marker detection system is also provided.

Antenna system including simultaneous phase aiding and phase canceling elements

A factory scale process for producing crystalline atorvastatin calcium includes the step of drying the isolated product in a vacuum pan dryer. The vacuum pan dryer has an agitator which is continuously rotated at a speed of approximately 1 rpm. High quality material is routinely and consistently produced with reduced cycle time.
