摘要： The time detecting apparatus receives repetitive binary coded sets of data including time data in a predetermined format. The components of a single set of the received data representative of time are detected and stored. After a preselected time interval the detecting means are again actuated to determine the time components from a successive binary coded set of the received data and the previously stored time components are updated by the preselected time interval. The updated stored time components are then compared with the time components of the latter detected successive set of data to generate signals indicating whether or not the respective sets of time components are identical to determine that the detected time components are accurate. If the compared sets of data are identical then the updated data is read out from the storage means to provide accurate time signals for timing and setting local clocks and other control functions.

摘要： In a receiver an automatic signal identification and synchronization circuit is utilized to identify the transmitting station and to synchronize internally generated commutating gates with the received signal. The received RF signal format is compared with a selected series of commutating gates by utilizing an up/down counter and a series of synchronizing control gates to either advance or retard the series of internally generated gate pulses. By solely retarding or advancing the commutating gates synchronization with the incoming RF signal format is achieved. A filter and envelope detector is utilized in the identification and synchronization circuit which passes no signal in a high noise environment thereby eliminating false synchronization.

摘要： An air traffic system in which participating aircraft occupy uniquely assigned time slots and have first time clock means which are assumed to be already finely synchronized to a groundbased master time clock by signal exchanges with ground stations and have second time keeping means in each aircraft which are synchronized first to the master time clock and are thereafter further and more finely synchronized to other aircraft nearby, to provide a desirable degree of redundancy while also remaining within the limits of the ground station imposed synchronization. Each aircraft in the illustrative embodiment selects by time-slot designation another nearby aircraft as its synchronizor, and in addition also responds to requests for synchronization by other synchronizee aircraft identified by other time-slot selection. This redundant fine synchronization among nearby synchronizor and synchronizee aircraft is especially useful in situations where large numbers of aircraft are flown close together in formations, or in groupings of commuter aircraft, for instance, in which STOL aircraft fly between cities close together, perhaps one behind the other.

摘要： A radio signal controlled oscillator is provided as a local frequency standard by synchronizing the oscillator using a phaselock servosystem comprising a long term integrating device as a voltage variable capacitor in the resonant circuit of the oscillator. The device consists of two columns of mercury separated by a substantial gap of electrolyte in a chamber made of dielectric material. Upon comparison of the oscillator signal with the radio signal, any error signal developed is applied across the electrolyte gap to the mercury column to transfer mercury from one to the other by the process of electrolysis. Conductive material wrapped around the chamber serves as a second plate of a capacitor for each of the columns one of which is used as part of the voltage variable capacitor. Means is provided for detecting the loss of the radio signal to interrupt any further change in the variable capacitor until the radio signal is restored.
