Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
87 words
IN A RADIATION SURVEY TRAINING APPARATUS: MEANS FOR TRANSMITTING RADIO SIGNALS SIMULATING THE EMISSION FROM A NUCLEAR BLAST FALLOUT, COMPRISING AN ANTENNA INCLUDING A VERTICAL RADIATOR, A PLURALITY OF ANGULARLY SPACED HORIZONTAL RADIALS DISPOSED IN A PLANE AT RIGHT ANGLES TO SAID RADIATOR; AND A PLURALITY OF RADIALS DISPOSED IN A SECTOR DIAMETRICALLY OPPOSITE SAID HORIZONTAL RADIALS AND INCLINED DOWNWARDLY SO AS TO SUBTEND AN OBTUSE ANGLE WITH SAID RADIATOR, WHEREBY TO RADIATE SAID SIGNALS OVER AN AREA HAVING AN OVAL CONFIGURATION SIMULATING A NUCLEAR FALLOUT PATTERN.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
130 words
RADIATION SURVEY TRAINING APPARATUS COMPRISING: A RADIO TRANSMITTER INCLUDING MEANS TO GENERATE A CONTINUOUS SUCCESSION OF RADIO FREQUENCY OSCILLATIONS FOR DEVELOPMENT INTO TRANSMITTED RADIO SIGNALS; MEANS FOR AMPLIFYING SAID OSCILLATIONS; A RISE AND DECAY CONTROL UNIT OPERABLE TO VARY THE SIGNAL STRENGTH OF SAID OSCILLATIONS IN RESPECTIVE STAGES OF RISING AND DECAYING SIGNAL STRENGTH SIMULATING THE RISE AND DECAY OF NUCLEAR FALLOUT EMISSION; SELECTOR FOR SELECTIVELY OPERATING SAID RISE AND DECAY UNIT SO AS TO CONFINE THE OPERATION OF THE APPARATUS TO EITHER A RISE STAGE OR A DECAY STAGE OF OPERATION; SAID APPARATUS FURTHER INCLUDING, IN SAID SELECTOR, MEANS FOR EFFECTIONG SUCCESSIVELY STAGES OF RISE AND DECAY OPERATION; AND MEANS IN SAID RISE AND DECAY CONTROL UNIT TO EFFECT AUTOMATIC TRANSITION FROM THE RISE STAGE TO THE DECAY STAGE.
