摘要： 1. A radio pulse signalling system comprising, oscillator means generating first timing wave which is comprised of a controlled number of cycles, means transmitting a pulse signal at the start of said timing wave, means transmitting a selectable number of pulse signals in response to only certain of said cycles in said timing wave so as to thereby convey the intelligence of transmission, means transmitting a pulse signal in response to a random number of the remaining cycles in said timing wave so as to thereby dissemble the intelligence of transmission, means receiving said pulse signals at a remote point, pulse generator means producing in response to the first received pulse signal a controlled number of regularly recurrent pulses the periodicity of which is harmonically related to said timing wave, vacuum tube means responsive to the first of said recurrent pulses holding said receiving means operative only prior to the production of said first recurrent pulse, counter means responsive to said regularly recurrent pulses generating a second time wave harmonically related to said first timing wave and comprised of a controlled number of cycles, said counter means adapted to render said receiving means operative only in response to those of said cycles of said second timing wave defined by the arrival of said pulse signals which convey the intelligence of transmission and inoperative in response to the remaining cycles of said second timing wave, vacuum tube means counting the number of pulse signals conveying the intelligence of transmission, and means recording the count of last said vacuum tube means whereby the intelligence of transmission is reproduced.
