Title: Synchronized demodulation system
IPC: H04N5/04
Filed: 1973-12-27
Abstract: 1451337 Synchronous detectors NIPPON ELECTRIC CO Ltd 27 Dec 1973 [29 Dec 1972] 59780/73 Heading H3Q In a receiver a received modulated carrier wave which includes synchronising pulses is sampled in order to develop a synchronised carrier wave for demodulation, the synchronised carrier wave being fed to a demodulator to regenerate a transmitted signal from which regenerated signal synchronising pulses are fed back to the means for developing the carrier wave for demodulation, whereby the sampling can be performed more stably. A carrier modulated with video wave which includes both line and frame synchronising signals is fed to synchronous demodulator 5, and an output obtained via low-pass filter 6; the carrier wave is also applied to a sampling circuit 1 which feeds carrier waves to the demodulator 5 via band-pass filter 4. The video output from filter 6 is fed to a sync. pulse separator 3 comprising amplifier 303, peak damper 302 and slicer 301 which synchronises pulse generator 202 via OR gate 201; pulses from pulse generator 202 open the sampler 1 during the sync. pulse periods of the carrier wave and it is the carrier wave during these periods which is applied to demodulator 5. The incoming signal is also applied to a circuit 7 for separating frame sync. signals and which applies a second input to OR circuit 201 to synchronise pulse generator 202 before the steady state of the retroactive loop 3 has been established. Circuit 7 comprises an emphasis circuit 701 which rejects carrier frequency and the adjacent sidebands corresponding to low modulation frequencies, an amplifier 702 and a slicer 703, which drives monostable multivibrator 704. Monostable multivibrator 704 produces a rectangular pulse during the period in the frame blanking that line sync. pulses are absent, and this is applied to drive a stable multivibrator 705; this drives sampling pulse generator 2 to generate pulses which cause sampler 1 to be operative during this period. The arrangement is intended for use with signals e.g. of the vestigial sideband type, in which peak modulation is over 100% and consequently the phase of the carrier is reversed during these periods. The Specification also describes known arrangements in which the carrier wave is developed by means of a sampling circuit driven from a pulse generator synchronised from a sync. separator coupled to the input line (Fig. 1, not shown), or in which the sampling circuit is synchronised from a sync. separator coupled to the output of the sampler (Fig. 2, not shown).

Title: Method and apparatus for automatically testing multiple-conductor cables
IPC: G01R31/02
Filed: 1971-12-23
Abstract: 1370109 Testing cables SOC FRANCAISE D'EQUIPEMENTS POUR LA NAVIGATION AERIENNE 23 Dec 1971 [28 Dec 1970] 60043/71 Heading G1U In a method of testing a cable harness, its responses to a succession of stimuli are compared with those from a reference harness or simulated harness (e.g. by a printed circuit board) known to be faultless. As described corresponding pairs of terminals, one from the cable CC, Fig.2, under test and one from the reference cable SR, are connected firstly to comparators A1, A2, ..., A6, secondly via resistors R1, R'1, ..., R6, R'6, to a positive supply terminal, and thirdly to ganged contacts K1, ..., K6. In operation, the ganged contacts K1, ..., K6 are closed singly, automatically in succession (Fig. 2 shows contacts K1 closed) until one, or more than one, comparator detects different responses. This is arranged to stop the switching sequence with the last contact that closed remaining in its closed position. Fig.2 shows an example of possible connections within a cable harness. Fig.5 shows at #, a possible fault caused by a blob of solder resulting in a connection that should not be present. With the fault shown in Fig.5, when the first contact pair K1 closes different responses are detected by comparators A2, A3 and A5. This causes the switching sequence to be stopped so that an engineer can note (a) the contact K which produced the different responses, and (b) the comparators at which the different responses were detected. The engineer can then cause the switching sequence to resume, and when it is complete it is hoped that an analysis of the results will yield information about the faults in the cable under test. A system is outlined for controlling the sequence by a counter which is stepped by clockpulses, detection of an incorrect response stepping the counter and causing the count reached to be indicated, until an engineer depresses a "continue" key.

Filed: 1978-10-05
Abstract: Certain conduits, such as gas pipes (3), have to be supported a certain distance from any wall (2) over which they run, and must not be left exposed. The first requirement is met by a cradle (1) screwed or nailed to the wall and which locates the conduit in a longitudinal recess (9). The conduit is secured by one or more retaining members (10) which clip onto the cradle, straddling the conduit. Concealment is achieved by a U-section canopy (15) which clips onto the retaining member(s). At one end the canopy terminates in a sloping roof (17) and at the other end it has a different cross-section to allow overlap with a portion of a similar canopy. The clips (12, 14) are integral with the retaining member and engage in apertures (13, 16) in the cradle and the canopy. <IMAGE>
