Polarisers for very high frequency electro-magnetic waves

Claim 1

AN ADJUSTBLE POLARIZER FOR PROVIDING EITHER ELLIPTICALLY OR LINERALY POLARIZED ELECTROMAGNETIC WAVES FROM INPUT LINEARLY POLARIZED WAVES COMPRISING FIRST AND SECONE COLINEAR, COAXIAL, CIRCULARLY SECTIONED LENGTHS OF WAVEGUIDE, SAID SECOND LENGTH OF WAVEGUIDE BEING THE ABLE RELATIVE TO SAID FIRST LENGTH OF WAVEGUIDE ABOUT THE COMMON AXIS THEREOF, MEANS FOR APPLYING LINEARLY POLARIZED WAVES TO SAID FIRST LENGTH OF WAVEGUIDE, A PAIR OF SPACED CONDUCTOR UNITS EXTENDING DIAMETRICALLY WITHIN SAID FIRST LENGTH OF WAVEGUIDE AT AN ANGLE OF SUBSTANTIALLY 221/2 DEGREES TO EACH OTHER, A THIRD CONDUCTOR UNIT EXTENDING DIAMETRICALLY WITHIN SAID SECOND LENGTH OF WAVEGUIDE AND ROTATABLE THEREWITH BETWEEN AN ANGULAR RANGE OF PLUS OR MUNUS 221/2 DEGREES WITH RESPECT TO THE NEAREST OF SAID PAIR OF SPACED CONDUCTOR UNITS, AND MEANS FOR RELATIVELY PHASE DELAYING TO AN EXTENT TO PROVIDE THE REQUIRED DEGREE OF ELLIPTICITY OF POLARIZATION, COMPONENTS OF THE OUTPUT WAVES FROM SAID SECOND LENGTH OF WAVEGUIDE WHICH ARE RESPECTIVELY PARALLEL AND PERPENDICULAR TO THE CONDUCTOR UNIT WHICH IS NEAREST TO THE INPUT END OF SAID FIRST LENGTH OF WAVEGUIDE.
