Title: Electronic ignition system

Filed: 1974-10-21
Abstract: 1465994 Electronic ignition system BL POLO 21 Oct 1974 [17 April 1974] 45482/74 Heading F1B An electronic ignition system comprises a transducer in the form of a first generator 10 generating pulses of predetermined fixed amplitude and duration at a frequency dependent on engine speed, a second pulse generator 16 producing pulses of variable duration, the trailing edge of the pulse initiating the switching-off of a semi-conductor switch 30 controlling an ignition coil 82, and providing a feedback signal to an electronic spark advance means, 26 effective to determine the duration at the pulses from generator 16 and hence to determine the timing of the ignition. The trailing edge at the pulses from generator 16 are detected by a monostable multi-vibrator 64 which produces an output applied simultaneously to the semiconductor switch 30 and to the electronic spark advance means. The advance means includes an electronic "characteristic" function generator 102. A vacuum advance bias switch 106 responsive to inlet manifold depression is effective to shift the function generated by generator 102 to advance the spark appropriately when the engine is not under load. The output signal is fed to a variable controlled monostable multi-vibrator 60 forming part of the second pulse generator 16. As shown, the first pulse generator includes a notched disc rotating with the crank-shaft and an electromagnetic pick-up 52. Again, the notches in the disc may be replaced by lobes, or a non-ferrous disc may carry magnetic inserts. Examples of specific electronic circuits for the circuit components one shown.

Title: Improvements in or relating to echo sounding apparatus
Inventor: HOPKIN PETER ROY
IPC: G01S7/534
Filed: 1963-11-19
Abstract: 1,033,988. Echo-sounding. SMITHS INDUSTRIES Ltd. Nov. 6, 1964 [Nov. 19, 1963], No. 45590/63. Heading H4D. In a marine echo-sounder for producing a chart record covering the region adjacent to the sea-bed, in which the echoes are locked to the sea-bed echo and the sea-bed echo appears as a straight line on the chart, echo signals arising from the transmission of an acoustic pulse are received and stored in a cathoderay storage tube and are read out into a chart recorder in the interval before the arrival of the next set of echo signals. The chart recorder is of the electrochemical type having a stylus 8 carried by a rotating arm 6 on a shaft 7. 'A transducer 21 is pulsed by a transmitter/receiver unit 20 triggered by a cam-operated switch on shaft 7. Echo signals detected by the transducer 21 are passed through the transmitter/receiver 20 to an amplitude gate 25 (as in Specification 785,001), a slope/amplitude gate 30 (as in Specification 878,111), and to a grid of the storage tube, 23, for intensity-modulating the electron-beam. Gate 30 generates a sharp output pulse on receipt of the main sea-bed echo pulse, while gate 25 blocks the transmission pulse and secondary sea-bed echo pulses and passes only the main sea-bed echo pulse to trigger a monostable circuit 26 into its unstable state, the circuit 26 remaining in its unstable state until about 25 mS before the arrival of the next main sea-bed echo pulse. Control potentials for selectively operating the storage tube 23 in a " write " mode and a " read " mode are provided by a circuit 24. A signal generator 27 provides an electron beam deflection waveform (g) and a tube blanking waveform (h) (Fig. 2, not shown) and is triggered from the monostable circuit 26, the gate 30, and a cam-operated switch 31, 32 on shaft 7. The arrangement is such that the electron beam scans in one direction for storing echo signals during the 25 mS interval, and scans in the opposite direction while echo signals are read out to the chart recorder during the period for which the monostable circuit 26 is in its unstable state. The " read " scan is initiated by the switch 31, 32 as the stylus 8 engages the chart 3 of the recorder, so that the echoes are recorded in the reverse order from that in which they were stored, with the sea-bed echo appearing as a straight line 34. The depth range recorded may be varied by adjusting the position of the camoperated switch which triggers the transmitter/ receiver 20, and the time-scale of the recording may be expanded by slowing the " read " scan rate relative to the " write " scan rate. In a modification, the electron beam may make a rapid fly-back after the " write " scan so that the " read " and " write " scans are both made in the same direction and the recorded echoes appear in the same order as the stored echoes. In other modifications, separate " reading " and "writing" electron beams, deflectionmodulation instead of intensity-modulation, and electromagnetic deflection, may be used.

Title: Time-division multiplex telecommunications systems

Filed: 1970-09-29
Abstract: 1318981 Multiplex pulse signalling SIEMENS AG 29 Sept 1970 [30 Sept 1969] 46146/70 Heading H4L In a time division multiplex system (a) comprising pulse frames PR in which each channel time slot includes eight bits, one bit of which is used for supervisory signalling, the supervisory time slot-element (b) of the first channel of each frame is also used to carry a frame synchronizing signal (e) in which binary 1 is transmitted every four frames and is combined with the binary supervisory signal (c). Without the sync. signal the signal (b) will be transmitted as pulses (d) over a plurality of frames. In a known arrangement, the effect of the sync. pulses is to invert the supervisory signal pulse each time a sync. pulse occurs (f), but this can lead to loss of synchronism at the receiver since some of the sync. pulses are lost. In the present invention, if the synchronizing signal repeats itself after a period consisting of x frames, at the first change in binary state of the supervisory signal the synchronizing signal is shifted by x/2 frames if x is an even number and by x + 1/2 frames if x is an odd number. After a second change in binary state of the supervisory signal, the synchronizing signal is shifted again by x/2 frames if x is even and by x-1/2 frames if x is odd and so on. This is shown at (g) for x=4, the first change in the supervisory signal occurring at sync. signal element 3 which becomes element 1 and the second change occurring at element 2 which becomes element 4. When the sync. signal treated in this manner is combined with the supervisory signal pulses the resultant signal (g) always contain a sync. pulse (binary 1) in the required time position. At the receiver, the sync. signals are extracted in conventional manner. To extract the supervisory signals, each signal element (g) is compared with the two signal elements preceding it and if it coincides with at least one of them it is assumed that it has the correct binary state of the supervisory signal, whereas if it does not coincide with either of the two elements the correct binary state is taken to be that of the two elements. By this means the pulse train (h) is obtained which is euivalent to pulse train (d) phase shifted and from this the supervisory signal (i) is derived.
