Device for the use in frequency of a short duration electrical signal

Claim 1

A device for storing a short duration signal comprising a read-in-station having an input means for receiving the signal, a read-out-station having an output means for transmitting the signal, a first signal delay means, a second signal delay means, said stations and said delay means being serially connected to form a closed signal-recirculation loop with said second signal delay means being located to receive the signals from said first signal delay means, phase comparator means connected to said read-in-station and to a point of said loop between said first and second delay means, means for adjustably phase shifting a signal circulating between said read-out-station and said second delay means, and phase shift control means coupling said phase comparator means and said means for adjustably phase shifting the circulating signal, whereby the transit time around the loop of the circulating signal is so controlled as to provide at the read-out-station a signal in phase with the signal introduced at the read-in-station.

Claim 2

A device for storing a short duration signal comprising a read-in-station having an input means for receiving the signal, a read-out-station having an output means for transmitting the signal, a first signal delay means, a second signal delay means, said stations and said delay means being serially connected to form a closed signal-recirculation loop with said second signal delay means being located to receive the signals from said first signal delay means, phase comparator means connected to said read-in-station and to a point of said loop between said first and second delay means, means for adjustably phase shifting a signal circulating between said read-out-station and said second delay means, and phase shift control means coupling said phase comparator means and said means for adjustably phase shifting the circulating signal, whereby the transit time around the loop of the circulating signal is so controlled as to provide at the read-out-station a signal in phase with the signal introduced at the read-in-station.

Claim 8

A device for frequency processing a short duration signal comprising: a. a first recirCulating signal loop having a read-in-station with an input means for receiving the signal and a read-out-station with an output means for transmitting the signal, distinctly located first and second delay means in said loop, said second delay means being downwstream of said first means in the sense of circulation of the signal along said loop, phase comparator means connected to said read-in-station and to a point of said loop between said first and said second delay means, means for adjustably phase shifting said circulating signal between said read-out-station and said second delay means and phase shift control means coupling said phase comparator means and said means for adjustably phase shifting the circulating signal; b. a voltage controlled oscillator; c. means for adjusting said voltage controlled oscillator to the frequency of the signal received at said read-out-station; d. a second recirculating signal loop selectively coupled to said read-out-station and to said voltage controlled oscillator, said second loop including third delay means and another phase comparator means connected to said read-out-station and to said third delay means, third means for adjustably phase shifting the signal circulating in said second loop, phase shift control means coupling said phase comparator means and said third means for adjustably phase shifting the circulating signal; and e. means for adjusting said voltage controlled oscillator to a predetermined frequency, close to that of the signal which is to be frequency processed when transmitted from said read-out-station.
