Claim 1
Independent Claim
103 words
A DEVICE FOR ADJUSTING THE INDUCTIVE COUPLING OF A HIGH-FREQUENCY ELECTROMAGNETIC FIELD TO A STATIONARY CONDUCTOR, COMPRISING FIRST COUPLING MEANS RIGIDLY MOUNTED ADJACENT TO SAID CONDUCTOR AND HAVING A FIRST ELECTROMAGNETIC FIELD IN CONTACT WITH SAID CONDUCTOR, ROTATIVELY MOUNTED SECOND COUPLING MEANS HAVING A SECOND ELECTROMAGNETIC FIELD ALSO IN CONTACT WITH SAID CONDUCTOR, AND MEANS FOR ROTATING SAID SECOND COUPLING MEANS ON AN AXIS PERPENDICULAR TO SAID CONDUCTOR SO THAT SAID SECOND ELECTROMAGNETIC FIELD WILL SUBSTANTIALLY CANCEL SAID FIRST ELECTROMAGNETIC FIELD AT ONE POSITION OF ROTATION SO THAT THE RESULTANT ELECTRIC FIELD COUPLING SAID CONDUCTOR IS SUBSTANTIALLY REDUCED TO ZERO AT SAID POSITION.
