Abstract: 1345028 Monitoring line repeaters DE STAAT DER NEDERLANDEN TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJEN TELEGRAFIE EN TELEFONIE 19 April 1971 [13 March 1970] 22810/71 Heading H4R A video signal is transferred from a source C to a receiver M over a line including repeaters L. Monitoring devices F are provided in each of the line sections to respond to the absence of line synchronizing pulses to inject into the line a characteristic signal which can be monitored at the receiver to determine the section nearest the transmitter from which a signal can reach the receiver. As described the monitoring device, Fig. 2, comprises a line synchronizing pulse detector 1 which during reception of the correct line pulses maintains relay A operated. If line synchronizing pulses fail relay A releases, causing opening of the through path of the line from 9 to 10, energization of the characteristic signal generator 3 via the relay B, termination of the incoming line section with resistor R2, and connection of the output of generator 3 to the outgoing line section from 10. The characteristic signal generator comprises a shift register 12, Fig. 4, which is shifted by a clock pulse generator 11 and in which the output of all the seven stages are fed back through a "NAND" gate 13 to the input stage of the register, the arrangement providing a signal at 20 comprising ,20, Fig. 5, seven "1"s followed by a "0". The stages of the register are connected through switches 15 to 19 to respective stages of a second "NAND" gate 14 whose inputs are biased to the "1" state by resistor R7 to R11 so that the output, 21, Fig. 5, is zero except when the "0" state of a stage of register 12 is connected by a respective switch to one of the "NAND" gate inputs. The output from the "NAND" gate 14 is mixed with the attenuated output of "NAND" gate 20, providing a synchronizing signal, giving an output signal as shown at 8, Fig. 5.

Abstract: 283,985. Smith, W. S., McLachlan, N. W., and Jacob, W. G. R. Sept. 21, 1926. Perforated strip transmitters; distributor systems. - Energy radiated from a source 6 reaches one or other of two detectors 7, which control the emission of cable code signals, through a perforated tape 3 carried by a drum 1, according as a perforation occurs on one or the other side of the tape. The surface of the drum is formed with slots 4 narrower than the perforations 5, and the energy pencil passes through an aperture between shutters 8, 9 the latter of which is adjustable. The beginning and the duration of a signal is accurately determined by the adjustment of the shutter 9 and the width of the slots 4; thus the device can be used to ensure an accurate division of the line time between the channels of a multiplex telegraph of the distributor type. The type of energy employed may be (a) visible, ultraviolet or infra-red radiation detected by means of a photo-electric cell or thermo-couple; (b) short wireless waves, detected by a coil or straight wire with an inductance at its centre, tuned to the fundamental or to a harmonic of the transmitter; (c) sound or supersonic waves derived from a valve-maintained reed or diaphragm or a piezo-electric oscillator, and detected either with a tuned reed or diaphragm which induces electromagnetically into a circuit, or with a condenser whose capacity is varied by the incident waves or by a piezo-electric crystal whose resulting e.m.f. is amplified thermionically.
