Radiation sensing system for automatically guiding

Claim 1

AN AUTOMATIC STEERING SYSTEM FOR GUIDING AIRCRAFT HAVING WHEEL LANDING GEAR ALONG A PREDETERMINED PATH ON A METALLIC LANDING SURFACE INTO A DESIRED POSITION FOR LAUNCHING SAID AIRCRAFT, COMPRISING AN ELONGATED, OPEN TOP, STAINLESS STEEL CONTAINER HAVING A WALL THICKNESS OF APPROXIMATELY ONE INCH AND SECURED TO SAID SURFACE ALONG SAID PREDETERMINED PATH, A STAINLESS STEEL CAPILLARY TUBE DISPOSED IN SAID CONTAINER HAVING A WALL THICKNESS OF APPROXIMATELY ONE HUNDREDTH OF AN INCH, A GAMMA RAY SOURCE WITHIN SAID TUBE HAVING AN EMISSION RATE OF ONE MR. PER HOUR AT A DISTANCE OF ABOUT EIGHTEEN INCHES, SAID LANDING GEAR INCLUDING AN OUTER TUBE WITH A WHEEL SUPPORTING INNER PISTON TUBE FOR SWIVELABLE MOVEMENT THEREBETWEEN, A RING GEAR ROTATABLY MOUNTED ON SAID OUTER TUBE, LINK MEANS CONNECTING SAID RING GEAR AND INNER PISTON FOR TRANSMITTING ROTATIVE MOTION THEREBETWEEN WHILE PERMITTING TELESCOPIC ACTION BETWEEN SAID TUBE AND SAID PISTON, A REVERSIBLE MOTOR SUPPORTED ON SAID OUTER TUBE HAVING A PINION MESHED WITH SAID RING GEAR FOR ROTATION THEREOF, A PAIR OF GAMMA RAY DETECTORS SUPPORTED FROM SAID OUTER TUBE ABOVE SAID CONTAINER FOR DETECTING UNEQUAL AMOUNTS OF GAMMA EMISSIONS WITH LATERAL MOVEMENT OF SAID LANDING GEAR RELATIVE SAID PATH AND PRODUCING ELECTRICAL SIGNALS, AND CIRCUIT MEANS COUPLING SAID DETECTORS TO SAID MOTORS FOR ACTUATION THEREOF UPON PRODUCTION OF SAID UNEQUAL SIGNALS.
