Aircraft landing system

Claim 1

AN AIRCRAFT LANDING SYSTEM, INCLUDING MEANS FOR TRANSMITTING A DIRECTIVE BEAM, MEANS FOR MOVING SAID BEAM THROUGHOUT AN ANGULAR SWEEP WITH RESPECT TO A REFERENCE LINE OF DIRECTION, SAID ANGULAR SWEEP BEING SUBSTANTIALLY GREATER IN EXTENT THAN THE EFFECTIVE ANGULAR WIDTH OF THE BEAM IN THE DIRECTION OF ITS MOTION, WHEREBY AN AIRCRAFT IN THE SPACE SWEPT BY THE BEAM WILL RECEIVE SAID BEAM ONLY WITHIN A RELATIVELY SMALL PART OF THE COMPLETE SWEEP OF THE BEAM, MEANS FOR MODULATING SAID BEAM BY A CONTINUOUS SUCCESSION OF REPETITIVE PLUSES, AND MEANS FOSR VARYING THE REPETITION INTERVAL BETWEEN SAID PLUSES WITH THE MOTION OF SAID BEAM TO REPRESENT THE ANGLE OF THE BEAM WITH RESPECT TO SAID REFERENCE LINE AS A SUBSTANTIALLY LINEAR DIRECT FUNCTION OF SAID ANGLE, SAID INTERVAL VARYING FROM A MINIMUM VALUE WHEN SAID ANGLE IS ZERO TO A MAXIMUM VALUE WHEN SAID ANGLE IS AT ITS MAXIMUM, AND THUS REPRESENTING THE VALUE OF SAID ANGLE MORE FREQUENTLY WHEN SAID ANGLE IS SMALL AND LESS FREQUENTLY WHEN SAID ANGLE IS LARGE, WHEREBY THE RATE AT WHICH AN AIRCRAFT IN SAID SPACE RECEIVES INFORMATION AS TO ITS ANGULAR POSITION IS GREATEST ON SAID REFERENCE LINE AND LESS IN REGIONS AWAY FROM SAID REFERENCE LINE.
