Abstract: A time-division-multiplex subscriber circuit provides the synchronous transfer of dial signals and teleprinter character signals into a time-division-multiplex system by means of a buffer and a pair of flip-flop devices in response to differences in the changes of polarity of the signals and at least one counter in cooperation with a divider for dividing the clock rate of the multiplex system down to the character signal repetition rate when one of the flip-flop devices is energized. The character signal repetition rate also controls the clock input of the buffer storage device so that the pair of flip-flop devices, the counter and divider become reset when the counter has reached a predetermined counting value.

Abstract: A first tachometer generator or other alternator having at least two phases and at least two poles, wherein the output of the first tachometer generator is full wave rectified. A second tachometer generator is also provided having one phase and at least four poles. The output of the second tachometer generator is full wave rectified to provide a periodic wave to match to the fundamental ripple frequency at the output of the first tachometer generator rectifiers and/or to eliminate the fundamental. An outstanding feature of the disclosure is that ripple elimination is achieved independent of generator speed. This is especially desirable in a vast number of controls including, but not limited to, speed controls for electric or other motors. The reason that this is desirable is that the ripple fundamental can be a very low frequency at low speeds and cannot be easily or inexpensively removed by filters. If not removed, the ripple can have a serious adverse effect upon the dynamic response and accuracy of the system in which a tachometer generator is used.

Abstract: A pass-band comb filter utilizes a series of strips and varactors in combination to form parallel resonant circuits at a particular frequency. The pass-band midfrequency can be varied in response to the bias voltage applied to the varactors. Additional capacitors and input and output strips are used to compensate for the insertion attenuation and for matching source and load impedance.

Abstract: A combined microwave and standard ILS system. Course information for at least one of the localizer and glide-slope functions is transmitted in the microwave frequency region, down-converted in the air and mixed into the clearance channels where it overrides standard clearance signals in substantially the same way as with standard ILS course signals on a landing approach. The system is compatible with existing airborne ILS equipment.

Abstract: An electronic switching module is provided for a switching system handling signals which have been subjected to Pulse Code Modulation. The module provides a path through two space switching stages to interconnect an incoming channel and an outgoing channel. A first one of the switching stages responds to an address information signal fed through a receiver register and a buffer register to connect a selected input to a second switching stage. The second switching stage responds to an enable signal to complete a connection through to the selected output line.

Abstract: A character block or logic circuitry is disposed between the line unit receiving telegraph characters on several lines and a central processing unit of a telegraph switching center. The character block reads out the characters stored in the line unit and, during transfer to buffer stores, analyzes the characters and send corresponding signals to the central processing unit. This arrangement reduces the work load on the central processing unit.
